How to use feng shui compass

How to use the compass How to use the geological compass

The magnetic declination must be corrected before using the geological compass. Because the geomagnetic north and south poles are not completely consistent with the geographical north and south poles, that is, the magnetic meridian does not coincide with the geographical meridian, and the magnetic north direction of any point on the earth is not consistent with the true north direction of that point. The included angle between these two directions is called magnetic declination. The east side of the northern end of the magnetic needle on the earth deviates from the true north direction, which is called the east deviation. Deviation to the west is called deviation to the west. The east deviation is (+) and the west deviation is (-). The magnetic declination of all parts of the earth is calculated and published as planned for future reference. If the magnetic declination of a point is known, the relationship between the magnetic azimuth A and the true north azimuth A of the survey line is that A is equal to the magnetic declination A. By applying this principle, the magnetic declination can be corrected. When correcting, you can turn the scale screw of the compass to make the horizontal dial turn left or right. Make the included angle between the north and south scale lines of the compass chassis and the 0- 180 degree connecting line of the horizontal dial equal to the magnetic declination. After correction, the reading is true orientation. (2) The measurement of target azimuth is to determine the relative position relationship between the target and the tester, that is, to determine the azimuth of the target (azimuth refers to the angle from the meridian clockwise to the measuring line). When measuring, loosen the brake screw to make the target plate point to the measured object. Even if the north end of the compass is facing the target and the south end is leaning against itself, aiming makes the target, the small hole of the target plate, the filament on the cover glass and the small hole of the target plate connect into a straight line, and at the same time centers the bubble of the chassis level. When the magnetic needle is at rest, the degree pointed by the compass is the azimuth of the measured object. (If the pointer can't stop temporarily, read half of the minimum degree when the magnetic needle swings. The same is true when measuring the readings of other components). If the board of the measured object is aimed at the tester (at this time, the southern end of the compass is facing the object), the reading of the compass indicates the direction of the tester. At this time, the reading displayed on the compass is the direction of the object. Compared with the former, this is because the north and south ends of the compass are just opposite when aiming at the object twice, which affects the relative position between the tester and the tester. In order to avoid reading fingers from time to time, sometimes reading the compass will cause confusion, so you should always read the compass with the target board pointing in the required direction, and the reading at this time is the azimuth of the object to be measured. (3) The spatial position of the measurement of the occurrence factors of rock stratum depends on its occurrence factors, including the strike, dip and dip angle of rock stratum. Measuring the occurrence of rock strata is one of the most basic working methods in field geological work. You must be familiar with it. 1。 The determination of strata strike is the direction of intersection between strata and horizontal plane, that is, the extension direction of horizontal line at any height of strata. When measuring, put the long side of the compass close to the stratum level, and then turn the compass to center the bubble in the chassis level, and the scale pointed by the reading pointer is the stratum trend. Because the trend represents the direction of a straight line, it can extend to both sides. The reading of compass or compass is just the extension direction of both ends of a straight line, such as NE30 degrees and SW2 10 degrees, which can represent the trend of rock strata. 2. Determination of strata strike-refers to the projection of the downward maximum dip line of strata on the horizontal plane, which is always perpendicular to the strata strike. When measuring, point the northern end of the compass or the receiving plate in an inclined direction, and the southern end of the compass is close to the floor, and rotate the compass to make the chassis level. Reading the scale pointed by the compass is the inclination of the rock stratum. If it is difficult to measure at the top of the rock stratum, you can still point to the inclined direction of the rock stratum at the bottom of the rock stratum, and the northern end of the compass is close to the bottom, so you can read the compass. If reading the compass is hindered when measuring the bottom surface, you can also read the compass when the southern end of the compass is close to the bottom surface of the rock. 3. It is correct to determine the dip angle of rock stratum as the maximum angle between rock stratum and imaginary horizontal plane. Measured along the true dip of rock stratum, the dip angle measured in other directions is apparent dip angle. Apparent dip angle is always smaller than true dip angle, that is to say, the angle between true dip angle on rock stratum and horizontal plane is true dip angle, and the angle between apparent dip angle on rock stratum and horizontal plane is apparent dip angle. It is very important to distinguish the true tendency of the field strata, which is always perpendicular to the strike. In addition, pebbles can be rolled or dripped on the stratum to make it flow on the stratum. This rolling or flowing direction is the true inclination direction of the stratum. When measuring, erect the compass with its long side close to the true dip line of the stratum, move the compass left and right along the stratum, move the adjustable wrench at the bottom of the compass with the middle finger to center the bubble of the inclinometer level, and read the maximum reading indicated by the middle tip of the hanging cone, which is the true dip of the stratum. The recording method of stratum occurrence is usually as follows: azimuth recording. If the strike of a certain stratum is 3 100, the dip angle is 2200 and the dip angle is 350, it is recorded as NW3 100/SW∠350 or 3 100/SW∠350 or 250. It is necessary to measure the occurrence of rock strata in the field.

What's the use of compass in real life?

How to use the compass The compass is an important tool for geomantic operation, and its basic function is orientation. When we know the knowledge of feng shui and gas management, we must first learn the basic method of using compass to orient. The scientific name of compass is compass, which was produced in the era of Xuanyuan Huangdi. It was made by predecessors according to the Book of Changes and the Heluo principle, and with the participation of the five-star seven strategies of the sun, the moon and the stars, by investigating the ups and downs of mountains, rivers and plains on the earth, and modifying and perfecting them. When it is used to determine the direction and survey the terrain, most geologists and sailors call it "compass" or "Luo Geng", but it is rarely used. Speaking of the use of the compass, I believe it will take up a lot of space if we discuss it in detail. Because it contains too many things, this article only talks about simple usage. There are many kinds of compasses. Commonly used are ternary disk, triple disk, ternary dual-purpose disk, easy disk, mysterious empty disk and unique disks of users of various genres. However, no matter which school's compass must have a layer of twenty-four mountains in the middle. From the north, they are Ren Zi Gui Chou Geng Yin Jia Mao Yi Si Ding Shen Geng You Xin Yao. You can find the relative degrees of compass and pointer as follows: azimuth divination position, twenty-four mountain angles, due north, Zigui, Ren Kan, 337.5-352.5-7.5, 7.5-22.5, ugly northeast, 22.5-37.5-52. 5，52。 5-67。 5, Zhengdong, Jia Zhen Mao Yi 67. 5-82。 5 8。 2.5-97.5 97.5-112.5 Xunsi Mountain in the southeast of Chen Xun112.5-127.5142. 5 65438。 202.5-217.5217.5-232.5, Wei Kun, southwest of Shen Kun. 5 262.5-277.5 277.5-292.5 Northwest China 292.5-307.5 307.5-322. 5 322。 5-337。 After knowing the direction of the twenty-four mountains, now let's look at the shape of the compass. As can be seen from the shape of the compass, in the center of the compass is a circular Tianchi (the compass is used for orientation). Outside is a movable turntable with gold lettering and copper face on the black background, which is called the inner disk or disk. The circle on the disk is full of words and is customarily called a layer. One layer has 24 directions, and the outermost layer is a square disk, which is called an outer disk or a square disk. The tray body is made of rosewood, but its weight is heavier than that of ordinary wooden tray. The outer disk has four small holes. There are two fishing lines or glue lines passing through the holes in the middle of the four sides, which are used to determine the sitting direction. Compasses are mainly used for central magnetic needles. The inner disk outside Tianchi Lake is made of steel, and the background color of Tianchi Lake is generally white. There is a red straight line at the bottom and two red dots at one end on the left and right sides of the red line. The red line is located in the north and south. On one side with the red dot is Zifang (due north), and on the other side is Noon Square (due south). There is a small hole at one end of the magnetic needle. When using the compass, hold the outer disk with your hands left and right, and separate your feet slightly. Place the compass between the chest and abdomen, and keep the compass level. Don't just sit back and wait. At this time, the crosshairs on the compass should be around the house. The measured sitting posture will be biased. After the position of the crosshairs is fixed, move the inner disk with both thumbs. When the inner disk rotates, Tianchi will also rotate with it. Rotate the inner disk until the magnetic needle stops and overlaps with the red line in Tianchi. It is important that the end of the magnetic needle with hole must coincide with the two little red dot on the red line. Positions cannot be lost to each other. At this time, the fishing line (horizontal line) showing the sitting direction intersects all layers of the inner disk. All kinds of data and materials we are looking for are displayed in the area where this fishing line passes through and covers. However, there are ten or twenty floors on the compass. Which floor is the direction of sitting? This is the bottom of the twenty-four mountains. It's near Tianchi. We use it to represent the "mountain" on the fishing line and the direction of the "mountain" on the fishing line. We use it to represent sitting. For example, children are sitting on the mountain, and those sitting on the mountain are at noon, so we call it sitting at noon. Knowing that you are sitting backwards in your house, you can put the compass in the center of the whole house.

How to use the compass correctly?

Compass is an important tool of geomantic omen, and its basic function is orientation.

When we know the knowledge of feng shui and regulating qi, we must first learn the basic method of compass orientation. Compass is called compass, which was produced in the era of Xuanyuan Huangdi, and later passed down by the sages of past dynasties. It is modified and improved by observing the ups and downs of mountains, rivers and plains on the earth according to the principles of Yijing and Heluo. It is used to determine the direction and survey the terrain. Most geologists and sailors call it "compass" or "Luo Geng", but it is rarely called "compass".

Speaking of the use of the compass, I believe it will take up a lot of space if we discuss it in detail. Because it includes too many things, this article only talks about simple usage.

There are many kinds of compasses, such as ternary disk, triad disk, ternary triad dual-purpose disk, easy disk, mysterious disk and unique disks of various school users. However, no matter what kind of compass it is, there must be a layer in the middle that is in the direction of the twenty-four mountains. From the north, they are Ren Zi Gui Chou Gen Yin, Jia Mao Yi Wei, Si, Bing Wu Ding, Shen, Geng Youxin, Xu Ganhai and so on.

There are 24 directions. If you have a compass, you can find that the relative degrees of the compass and the pointer are as follows: azimuth hexagon, twenty-four mountain angles, due north 337.5-352.5, Kanzi, 352.5-7.5, 7.5-22. 5 ugly, northeast 22. 5-37。 5，37。 5-52。 5 yin, 52. 5-67。 5 A, due east 67 5-82。 5, Mao 82. . 5-97。 5 B 97。 5- 1 12。 5 Chen 1 12. 5- 127。 5 southeast Xun 127. 5。 38+072.5 Zhengnan Congwu 172.5- 187.5 d 187.5-202.5 Fei 202.5-2 17.5 Southwest Kunkun 2 17.5-232. 5 Shen 232. 5-247。 5 Geng. Xin 277.5-292.5, 2000 292.5-307.5 Northwest trunk 307.5-322.5 Hai 322.5-337.5 Knowing the direction of the Twenty-four Mountains, we should now look at the shape of the compass.

As can be seen from the shape of the compass, the center of the compass is a circular Tianchi (that is, the compass used for orientation). Outside is a movable turntable with a copper surface and gold fonts on a black background, which is called an inner disk or an optical disk.

The circle on the disk is full of words, and it is customary to call a circle a layer. The first layer has 24 directions, and the outermost layer is a square disk, which is called the outer disk or square disk.

The tray body is made of rosewood, which is the most durable, but its weight is heavier than that of ordinary wooden trays. There are four holes in the outer disk, and the holes in the middle of the four sides pass through two fishing lines or glue lines respectively to determine the sitting posture.

Compasses are mainly used for central magnetic needles. The inner disk outside Tianchi Lake is made of steel. The background color of Tianchi Lake is generally white, and there is a red straight line at the bottom. There are two red dots on the left and right of the red line at one end. The red line is located in the north and south. One side with a red dot is Zifang (due north), and the other end is noon (due south), with a very sensitive magnetic needle on it. There is a small hole at one end of the magnetic needle. When using the compass, hold the outer disk with your hands left and right, and separate your feet slightly. Place the compass between the chest and abdomen and keep it horizontal, not left high and right low or front high and back low.

Then stand upright with your back as the seat and your face as the direction. At this time, the crosshair silk on the compass should coincide with the front, back, left and right positions of the house. If the crosshair direction is incorrect, the measured sitting posture will deviate.

After fixing the position of the crosshairs, move the inner disk with both thumbs. When the inner disk rotates, Tianchi will also rotate with it. Turn the inner disk until the magnetic needle stops and overlaps with the red line in Tianchi.

It is very important that the end of the magnetic needle with a small hole must coincide with the two little red dot on the red line, and the positions cannot be lost. At this time, it shows that the fishing line (horizontal one) sitting in the square intersects with each layer of the inner plate.

All kinds of data and information we are looking for are displayed in the area where this fishing line passes through and covers. However, there are ten or twenty layers on the compass. Which floor is the direction of sitting? That's the floor of the 24th mountain.

It's near Tianchi. We use the "mountain" in the direction of the fishing line to indicate the direction, and the "mountain" on the side of the fishing line to indicate sitting.

For example, a child facing the mountain is sitting on the mountain at noon, so we call it sitting in the afternoon. Knowing that you are sitting backwards in your house, put the compass in the center of the whole house, and you can find out the orientation of the whole house (or palace) from the sitting direction.

Second, the application of the compass "three disks and three needles" 1, the venue-used in the vertical direction-put a "compass or compass" on the Taiji point to measure all directions, and the Taiji point of Yangzhai is in the house; The crypt is in the center of the tomb top. 2. People's plates-used to remove sand-look at peaks, buildings, trees, walls, piles, towers, chimneys, etc.

3, the sky plate-used to receive water-look at the direction of water or roads coming and going. Such as water sources, rivers, ponds, wells, toilets (turbid water), fish farms (running water), doors and windows (running water), roads or flat land (empty or fake water), etc.

Three, the eight diagrams attribute water intake method: 1, the trunk branch Kunxun belongs to wood. 2. Ethyl-octyl-butyl-decyl soil.

3. Meridian belongs to fire. Chen Yu's ugliness is not gold.

5. Shen Yinyu Sea belongs to water. Four, gossip attribute: 1, Muketu Zhengcai.

2. Aquatic wood is expensive. 3, wood sees wood is prosperous.

4, wood fire for drainage. 5. Jin Kemu wants to kill.

Usage: For example, Kunshan is neither ugly nor ugly. Ding Chou didn't get any money, so he was promoted to four hexagrams and became a hexagram "Lei Fengheng hexagram". Sit on the mountain, rise to four hexagrams, and become "Lei Fengheng hexagrams" to check and judge.

Ray, Maki Yagi and Aunt Xun. This divination is broken: the east kitchen has land, two trees make a forest, and fame and fortune are both gained.

The land is prosperous, the eldest son and daughter live in harmony, the son is expensive in Sun Xian, the brothers and fathers respect him, he is rich and prosperous, and the family continues. Note: For this divination, please refer to Page 4 14 "Jumen Eight Bureaux Changing Images".

How to use the compass?

The compass is the operating tool of the Richie Sect, which is mainly composed of a magnetic needle located in the center of the disc and a series of concentric circles, each circle represents the ancient people in China's understanding of a certain level of information in the big cosmic system.

The ancients in China believed that man's gas field was controlled by the gas field of the universe, the harmony between man and the universe was auspicious, and the disharmony between man and the universe was fierce. Therefore, through experience, they put all levels of information in the universe, such as the stars in the sky, everything represented by the five behaviors on the earth, heavenly stems and earthly branches and so on. , all on the compass. On the other hand, Feng Shui seeks the most suitable position or time for a specific person or thing through the rotation of a magnetic needle.

Although the concept of "magnetic field" is not mentioned in geomantic omen, the coordination of direction, orientation and interval between layers on the compass implies the law of "magnetic field".

The invention and application of the compass is the result of human beings' continuous exploration of the mysteries of the universe, society and life. More and more circles and more complex pointer systems on the compass represent the accumulated practical experience of human beings. Of course, whether these experiences are comprehensive and correct needs further study, but the information marked on the compass contains a lot of ancient China wisdom.

Preservation and maintenance of compass

Compass is the basic tool of feng shui master, and should be kept in a clean and cool place when not in use. When going out, prevent the thimble from being damaged due to excessive bumps in the journey.

When using the compass, you should pay attention to prevent the sun from exposure and rain, especially the copper compass, which is easy to accelerate the disk falling off. Wipe with a soft cloth after use.

When the compass is not used, it should be placed in a flat place, and it is best to make the compass face down. Please stay away from power, metal and damp places.

As a measuring tool, compass should pay special attention to its maintenance. If mistakes are made due to improper maintenance, it may bring unimaginable consequences to people themselves and their families.

How to use compass in geology? Inclined strike line

1. The determination of stratum strike is the direction where stratum intersects with horizontal plane, that is, the extension direction of horizontal plane at any height of stratum. When measuring, the long side of the compass is close to the stratum, then rotate the compass to center the bubble of the chassis level, and the scale pointed by the reading pointer is the stratum trend. Because the direction represents the direction of a straight line, it can extend to both sides, and the compass or compass reading is the extension direction of both ends of the straight line. For example, NE30 degrees and SW2 10 degrees can both indicate the trend of rock strata. 2. Determination of strata dip-refers to the projection of the downward maximum dip line of strata on the horizontal plane, which is always perpendicular to the strike of strata. When measuring, point the northern end of the compass or receiving plate in an oblique direction, and the southern end of the compass is close to the plane. Rotate the compass to center the bubble of the chassis level. Reading the scale pointed by the compass is the inclination of the rock stratum. If it is difficult to measure at the top of the rock stratum, you can still point to the inclined direction of the rock stratum at the bottom of the rock stratum, and the northern end of the compass is close to the bottom, so you can read the compass. If reading the compass is hindered when measuring the bottom surface, you can also read the compass when the southern end of the compass is close to the bottom surface of the rock. 3. It is correct to determine the dip angle of rock stratum as the maximum angle between rock stratum and imaginary horizontal plane. Measured along the true dip of rock stratum, the dip angle measured in other directions is apparent dip angle. Apparent dip angle is always smaller than true dip angle, that is to say, the angle between true dip angle on rock stratum and horizontal plane is true dip angle, and the angle between apparent dip angle on rock stratum and horizontal plane is apparent dip angle. It is very important to distinguish the true tendency of the field strata, which is always perpendicular to the strike. In addition, pebbles can be rolled or dripped on the stratum to make it flow on the stratum. This rolling or flowing direction is the true inclination direction of the stratum. When measuring, erect the compass with its long side close to the true dip line of the stratum, move the compass left and right along the stratum, move the adjustable wrench at the bottom of the compass with the middle finger to center the bubble of the inclinometer level, and read the maximum reading indicated by the middle tip of the hanging cone, which is the true dip of the stratum. The recording method of stratum occurrence is usually as follows: azimuth recording. If the strike of a certain stratum is 3 100, the dip angle is 2200 and the dip angle is 350, it is recorded as NW3 100/SW∠350 or 3 100/SW∠350 or 250. It is necessary to measure the occurrence of rock strata in the field.

How to determine geographical position with compass

In order to determine the direction, in addition to the compass, there must be an azimuth dial. At first, there may be no fixed azimuth disk. With the need of azimuth measurement, a compass with magnetic needle and azimuth disk appeared. Compasses include Feng Shui Compass, Water Compass and Drought Compass. The azimuth disk is still 24-directional, but the disk has evolved from a square to a circle. In this way, we only need to look at the position of the magnetic needle on the azimuth plate to determine the azimuth. In the Southern Song Dynasty, Zeng Sanyi recorded the relevant literature in the Record of Yin Hua: "The snail either has meridian needles or sews them between needles." This is the earliest document record about the compass. The "snail" mentioned in the literature is the compass. The knowledge of magnetic declination has been applied to compass in literature. This compass not only has a meridian pointer (used to determine the direction of the north and south poles of the geomagnetic field) but also the angle between the meridian pointer and the meridian pointer (the direction of the geographical north and south poles is determined by the shadow of the sun), which is declination. There are 24 directions carved around the disk, which contain water. Now people know that the two magnetic poles of the earth are only close to the geographical North Pole and South Pole, but they do not overlap. The magnetic needle points to the magnetic pole of the earth rather than the geographical north and south poles, so the magnetic needle does not mean due south or due south. This angle is called magnetic declination. Because the earth is nearly spherical, the magnetic needle will tilt downward when pointing to the magnetic pole, and there is an angle with the horizontal direction. This included angle is called magnetic declination. Magnetic declination and magnetic declination are different in different places. When talking about making a compass by geomagnetic method, Shen Kuo noticed the use of magnetic declination. In Meng Qian Bi Tan, he talked about the incomplete guide of the compass, which often moves slightly eastward. He pointed out that
