Description of compass usage

Level 15 B: sixty-four hexagrams are placed on the beginning table.

This layer is the location of the 384 hexagrams of the first hexagram and the upper hexagram. The knife represents the first divination, and the upper divination represents the upper divination. The arrangement of hexagrams begins with the first hexagram, followed by the second and third hexagrams.

The sixteenth floor: sixty-four hexagrams in the sky, 384 degrees.

Seventeenth floor: Sixty-four hexagrams in the sky, six parents' view.

This layer is the six hexagrams in the sixty-four hexagrams. Each hexagram is accompanied by six relatives, which are divided into officials, ghosts, parents, brothers, wives, wealth and descendants. Six relatives are used to divide wealth.

18th floor: Twenty-eight stars

Twenty-eight stars, that is, the twenty-eight stars in the north and south of the ecliptic, and these twenty-eight stars are all attributed to the seven strategies and four wonders, namely, the present day, the moon, gold, wood, water, fire, earth, black dragon, suzaku, white tiger and Xuanwu.

19 floor: 28 stars.

This floor is the intensity of 28 stars, for reference when standing. It depends on the relationship between intensity and 28 stars to calculate the quality of each degree.

Twentieth floor: 360-day dial

The 360-week sky mark is a modern coordinate, which lets everyone know the position of each layer of the compass.

Structure of geological compass

There are many kinds of geological compasses, but their structures are basically the same. We often use a round basin geological compass. It consists of a magnetic needle, a dial, an inclinometer, an aiming plate, a level meter and other components installed in a copper, aluminum or wooden round basin.

magnetic needle

Generally, it is a diamond-shaped steel needle with a wide middle and sharp sides. It is installed on the thimble in the center of the chassis and can rotate freely. When not in use, the brake screw should be tightened, and the magnetic needle should be lifted and pressed on the cover glass to avoid the collision between the magnetic needle cap and the neck needle tip, protect the thimble needle tip and prolong the service life of the compass. When measuring, loosen the fixing screw so that the magnetic needle can swing freely. At last, at rest, the needle points to the meridian direction of the needle. Because the magnetic forces at the two ends of the magnetic needle located in the northern hemisphere are not equal, the magnetic needle is out of balance. In order to keep the balance of the magnetic needle, several turns of copper wire are often wound at the southern end of the magnetic needle, which is also convenient to distinguish the north and south ends of the magnetic needle.

Horizontal scale

The scale of the horizontal dial is marked as follows: starting from zero, it is marked counterclockwise every 10 degree, and it is engraved to 360 degrees. O degree and 180 degree are n and s respectively, and 90 degree and 270 degree are e and w respectively. It can be used to directly measure the magnetic azimuth of a straight line between two points on the ground.

t square

It is specially used to read the inclination angle and slope angle. The position of E or W is 0 degrees, and the position of S or N is 90 degrees. The corresponding numbers are marked every 10 degrees.

Hanging cone

It is an important part of inclinometer, suspended under the shaft of magnetic needle, and the suspension cone can be rotated with a wrench on the chassis. The scale indicated by the tip of the hanging cone center is the degree of inclination or inclination angle.

level vial

There are usually two, which are installed in circular glass tubes respectively. The circular level is fixed on the chassis, and the long level is fixed on the inclinometer.

gunsight

Comprise an object receiving plate and an object receive plate, wherein a thin line is arranged in that middle of the reflector, and a transparent hole is arranged at the lower part of the reflector, so that eye, the thin line and an object can aim on a line.

Geological method

The magnetic declination must be corrected before use.

Because the geomagnetic north and south poles are not completely consistent with the geographical north and south poles, that is, 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 declination.

At a certain point on the earth, the north end of the magnetic needle is called east deviation and the west deviation is called west deviation. The east is (+) and the west is (-).

The magnetic bias of all parts of the earth is calculated according to the timetable and published 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 positive or negative magnetic declination A.. Using this principle, the magnetic declination can be corrected. During calibration, the scale screw of the compass can be turned to make the horizontal dial turn left or right (the magnetic declination is east to right and west to left), so that 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 is equal to the magnetic declination. After correction, the reading during measurement is the true azimuth.

Measurement of target orientation

It 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 between the meridian clockwise and the survey line).

When measuring, loosen the brake screw and make the aiming plate point to the measured object. Even if the north end of the compass points to the target object and the south end leans against itself, aim at it, so that the target object, the small hole of the aiming plate, the filament on the cover glass and the small hole of the aiming plate are connected into a straight line, and at the same time, center the bubble of the chassis level. When the magnetic needle is at rest, the degree pointed by the north needle is the azimuth of the target object to be measured. (If the pointer can't stand still for a while, you can read half of the minimum degree when the magnetic needle swings, and the same is true when reading other elements).

If the paddle 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 tested.

In order to avoid the confusion caused by reading the compass from time to time, the compass should be read continuously when the object board points in the required direction, and the reading obtained at this time is the azimuth of the measured object.

Application of geological compass in wireless communication

In wireless network survey, compass is used to measure the azimuth of base station sector.

Indicates the direction of taking photos in a wireless environment.

Some can also be used to measure the antenna inclination.

Eight different air senses in the compass

Giant gate gas

That is, the same yin-yang divination system, the combination of men and women in the same generation is.

Such as: women, men, women, boys, girls, fathers and mothers.

They are the same generation and attract each other. They are a perfect combination. Those who are willing to accept or suffer indignities have a harmonious family, a happy marriage, filial children, good health, excellent studies, eternal youth, smooth career, and more help from nobles.

Gathering the door spirit is a hexagram of yin and yang, and it is also for men and women of the same generation, that is, superiors and subordinates, bosses and employees will work together and be polite to each other.

For example: direction C, and then open the door from the outer disk or receive air from the outer disk.

Vuquqi

That is the same divination system, the gender combination of different generations.

Such as: old father, female mother, male, male, female, male and female.

They are attracted by yin and yang of different generations in the same divination system, and their families will be harmonious. Husband and wife will understand each other, children will be filial, respect the old and love the virtuous, be healthy, have a good relationship, have a smooth career, and work wholeheartedly, but they will be honored.

Auxiliary gas

That is to say, tongbu is a combination of the same generation and the same sex, that is, with oneself, so it is called auxiliary qi.

Such as: father, father, mother, mother, male, male, female, female.

Long men, long men, young men, young men, young women, young women.

They are friends. With this game, a family can struggle together, work hard together, be honest with each other, have children, and develop their careers steadily. Fu Bi is the spirit of the same divination system, so it is concentric, but not attractive, so it is difficult for families to be rich, brothers, parents, etc. There is nothing to say, it is difficult for a career or company to make progress, and the fortune is not good. If you are in business, your guests don't hate you, but they just don't go in.

Hungry wolf

It is a same-sex combination of different generations of the same hexagram system.

Such as: old father, male mother, female long, male few, male long, female girl.

If the employees employed by the company are so angry, they will stand still, even worse than themselves. The sex maniac is a unisexual combination, which is unattractive and of different generations, and it doesn't help. It is very difficult to do this kind of business and study, and we must struggle by our own efforts. But the development is slow, there will be respect within the family and the company, the younger brother will respect the older brother, and the children will be clever and honest.

Lian Zhenqi

It is a sexual combination of different hexagrams (that is, red and white combination), and there is little difference between generations. Because the combination of the opposite sex is mutual attraction, it means good popularity.

Such as: old father, old daughter, old mother, old man, boy and girl, girl and boy.

Lian Zhen's Qi is a combination of different hexagrams between men and women. Although they will attract each other, because different hexagrams have different hearts and attract each other, that is, in the relationship between husband and wife, they will have a strange strange bedfellows with peach blossoms in full bloom, but on the surface, they will not make noise, love each other will not destroy the family, and each has its own object of worship. However, due to the great attraction of the opposite sex, the representative will make money and the business will be ok. However, it is often because of speculation failure or being deceived by the opposite sex that business people can't use this kind of anger to commit peach blossoms. If you make a peach blossom, you will break the money. If you don't make a peach blossom, you will be OK.

Lian Zhen, who does business with this spirit, will be glib, boastful and make money, but not for long. Such an angry child, on the surface, seems to be good at reading, but in fact he is reading some irrelevant books and thinking wildly.

Vinquzi

It is a combination of men and women with different hexagrams and generations.

Such as: old father, young girl, old mother, young boy, male eldest daughter, female eldest boy.

Although Wen Qu is very attractive to the opposite sex, his popularity is good. However, due to the great difference in seniority, he is easy to fantasize, unrealistic, negative, daydreaming, romantic and disrespectful, and will be shameless to commit peach blossoms. Marriage can easily break up because of an affair. I like old cows to eat young grass. The right hand makes money and the left hand is empty, and the career and studies are not ideal. The rest refers to natural gas in Lian Zhen.

Lu cunqi

Same-sex marriage, there are small generational differences between different hexagrams.

Such as: old father, old mother, old daughter, boy, girl.

Lu Cunqi's reason is that the divination system is different, the mind is different and the same sex repels each other. In this way, families will have their own ideas and will not unite. Disputes between father and son, mother and daughter, brothers, sisters and mother-in-law, the relationship between husband and wife will be bad, marriage will easily break down, ambition will be difficult to stretch, passive and enterprising, career will be difficult to achieve, interpersonal relationship will be bad, health status will be poor (that is, organs will repel each other), and many diseases will haunt you, such as repeated eight evils, stroke, cancer and other serious diseases. If the seats and desks are placed like this, the children will be disobedient and don't want to study.

Pojun qi

Same-sex combinations with great generational differences between different hexagrams.

Such as: father, boy, mother, girl, male, male, female, eldest daughter.

There are great differences among the gas chambers in Pojun. Different divinatory symbols are different, but they are mutually exclusive (same sex). Third, there are great differences between generations. This kind of air chamber is too dangerous. For example, the old father is the largest in the Yang Gua system, and the young man is the smallest in the Yang Gua system. Same-sex repulsion, poor study, poor health, seniority, easy to cause disputes and fights.

Pojun's anger is the fiercest, which can easily lead to family discord, unfilial children, childless families or single sex, easy for couples to turn against each other, and easy for marriage to break down, and he will not live long due to illness. If you commit eight evils again, you will be prone to stroke, cancer, accidents or car accidents. Your popularity will be poor and your career will be ruined. Talking about wealth is a way to make a lot of money.

Ancient books recorded eight phenomena on the compass.

Stay outside

The needle drifted into the needle. To the east: there are bones such as cows, cats and dogs underground; To the south: there are salty springs underground; To the west: there is a grave on the east side of the underground; To the north: there are magnets underground; Middle lining: There are ancient clocks and the like underground.

exchange

Sinking eastward: there are holes for bees, ants, snakes and insects; Sinking to the south: there are stone tools or rocks on the ground to the south; Sinking to the west: there are buried bodies underground in the west; Sink to the north: there are coffins underground; Zhongshen: There are ancient stone lamps buried underground.

contrary/opposite

The pointer flashes from north to south, or skips the pointer. To the east: there are spiritual objects underground; Reverse to the south: there are different mines underground in the northeast; West: there are magnets in the east of the underground; Reverse to the north: there are bones in the southwest of the underground; Neutral: there is gray charcoal and the like underground.

(of the sun) crossing the meridian.

The pointer does not point north, south, east or west. Xiang Changyu: There are stone tools underground; To the south: there are magnets in the southwest underground; Xi Chang: There is an empty place underground; North: there are gold and tin underground; Zhongyu: There are antiques and old treasures underground.

straight

Open the needle slowly and steadily, keeping the three threads in one. Dongzheng: there are peaks and stones in the west; To the south: there is a water hole underground in the northwest; To the west: there are ancient graves in the east; To the north: there are gold and silver treasures underground; Chiang Kai-shek: Baiji makes you feel at ease.

Taboos for using compasses

Compass usage:

When measuring the direction of a fixed object:

Step 1: put the compass flat so that it is close to or parallel to the edge of the measured object.

Step 2: Slide the turntable to make the hairpin head of the magnetic needle match the two points on the red line of the compass base.

Step 3: Locate the reading direction of the layer pressed by the transparent line.

Measure the direction of furnace: level the compass. Near the edge of the stove. If the furnace is made of iron, it will affect the swing of the magnetic needle, so it should retreat two or three feet vertically. The edge of the compass is parallel to the edge of the stove. Slide the turntable so that the hairpin head of the magnetic needle matches the two points on the red line. Reading direction.

Compass orientation measurement: how to use a compass or guide (north) needle to measure the orientation of a house.

Before using a compass or compass, the following points need special attention:

1, you must first remove all ironware, electrical appliances (mobile phones, walkman) or items that will interfere with the magnetic field of the compass.

2. Pay attention to the fact that there are no ironware, mobile phones, telephone poles, electric boxes, electric towers and other items that will interfere with the electromagnetic field near the measurement site.

3. The disk surface of compass or compass (north) needle must be horizontal, and the pointer cannot rise or fall at the same time. At the same time, we should also pay attention to whether the joint between the compass surface and the disk body is tight, and there should be no looseness or damage.

4, check whether the compass or guide (north) needle is normal, if bent, it shall not be used.

Correct compass orientation:

Hold the outer disk with both hands left and right, and separate your feet slightly.

Put the compass between the chest and abdomen, and keep it horizontal, not high on the left and low on the right, nor high on the front and low on the back.

Adjust the compass. The crosshair above the compass should be parallel to the door of the house.
