Field of the Invention The present invention relates to a compass, and more particularly to an electronic sundial compass that utilizes the shadow of the sun projection 5 to accurately measure and display the direction or position and a method of measuring using the compass. [Prior Art 1 Background of the Invention In many fields, such as construction, decoration, navigation, military, etc., it is necessary to accurately determine the direction. In general, magnetic fields are used in the above fields to determine the direction, such as a magnetic compass. The magnetic compass utilizes the nature of the Earth's own magnetic south and magnetic north poles, indicating the direction through a rotatable device with an indicator. In practical applications, the Earth's magnetic field near the magnetic compass may be disturbed by other magnetic fields or nearby iron-containing metals, so effective magnetic field compensation is necessary to obtain accurate orientation. The KMZ52 semiconductor device manufactured by PHILIPS is a two-dimensional magnetic field sensor specifically used for electronic magnetic compasses. It uses magnetoresistive (MR) technology and uses flipping technology to eliminate signal offset. In the prior art, there is an electronic compass using such a sensor 5, for example, the circuit of A in the fourth phase of the "Electronics World" is used to compensate the accuracy of the earth magnetic field and the characteristic of the sensor KMZ52 itself. Accurate electronic compass. Another device for measuring the direction is a gyrocompass, which measures the component of the angular velocity of the earth in different directions based on the principle of the speed gyro. The method of calculating the angular velocity of the earth is used to determine the orientation of the meridian, or the gyroscopic moment generated by the rotation of the ball at 200909776. Under the gyro rotor, the axial meridian is approached, and swings around the meridian to determine the north direction. SUMMARY OF THE INVENTION Summary Whether using magnetic yoke or using an electronic compass to measure direction, the accuracy of the measurement is affected by the nature of the earth's magnetic field itself and indeed the presence of other magnetic fields and iron-containing metals. At the same time, there is a certain angular deviation between the earth's magnetic pole and the real square. Even if the circuit is compensated, the accuracy is still not satisfactory, and a new influence on the accuracy factor may be introduced due to the electrical characteristics of the measuring device itself 10. The device using the gyro compass has a complicated structure, high cost, and speed deviation. There is therefore a need for an apparatus and method that is capable of accurately determining the direction of geomagnetism. The invention provides a compass device, comprising a casing, a positioning pin, a boring pin, a sensor and a circuit device, wherein the corona needle is a straight needle fixed to the rotation axis of the positioning pin, perpendicular to the plane of rotation of the positioning pin The sensor is fixed on the outer casing, and when the positioning pin rotates to coincide with the sundial needle shadow, the measured angle value of the measured object is sensed, and the circuit device disposed inside the compass device performs the above measured value and the inherent sunshade angle. Compare and output the difference information through the display device to display the azimuth of the measured object. In another aspect of the invention, the compass device further includes a rotating disk, wherein a center of the positioning pin is coaxial with a center of the rotating disk, and a positional relationship between the positioning pin and the rotating disk is kept fixed, the sensor It includes two parts, a light source and a photosensitive element. The present invention also provides a compass device, comprising: a housing, a positioning pin, a 6 200909776 boring needle, a reference disk and an inherent shadow angle calculating device, wherein the boring needle is a straight needle, fixed to the rotation axis of the positioning pin, Vertically perpendicular to the plane in which the positioning pin rotates, the reference disk has an angle information of 1-360 degrees, which can be rotated coaxially with the positioning pin, and senses the measuring angle of the object to be measured when the positioning pin rotates to coincide with the sundial needle shadow. The value is compared with the inherent shadow angle to calculate the azimuth of the measured object. The present invention also provides a method of measuring a position using a compass device, comprising the steps of: placing a 10 compass device including a housing, a positioning pin, a sundial needle, a sensor, and a circuit device under sunlight, and placing a straight needle The violent needle is fixed to the rotation axis of the positioning pin, perpendicular to the plane in which the positioning pin rotates, and rotates the positioning pin to turn the object to be measured, and rotates the positioning pin again to coincide with the day shadow of the needle, and The angle information of the difference between the measured object and the inherent shadow angle is output by the sensor, and the azimuth angle of the measured object 15 is displayed by using the circuit device. The northern part of the Earth's axis is called Zhenbei, and the true north is different from the magnetic north of geomagnetism. Since the measured orientation of the present invention is the orientation and angle brought by the north-south direction of the earth's axis, and is not the azimuth and angle brought by the geomagnetism, the direction of the invention is the true north direction, which is the earth's body. The true 20 orientation inside. The invention can utilize the shadow of the sun to determine the azimuth angle of the measured object, and the determined azimuth accuracy is high, and the interference of the geomagnetism is eliminated, and the electronic method can make the calculation faster and the reading orientation information is more convenient. The electronic corona compass device provided by the invention has a simple structure and a relatively low cost. 7 200909776 BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be further described in detail in conjunction with the following drawings: Figure 1 is a perspective view of an embodiment of an electronic day I compass of the present invention; and Figure 2 is a compass device in accordance with an embodiment of the present invention.

Change, the time, latitude and longitude are local information. There are a number of methods in the prior art for calculating the angle. For example, using the Clear Sky Institute, the method published on the website h.ttp://www.clearskyiristitute.com/xephem/jL, or the British Sundial Society on their website 20 http://www.simdialsoc. The method of org.uk/household public. Here, the contents disclosed in the above-mentioned website before the filing date of the present application are incorporated into the present application as prior art. For example, as shown in Fig. 3, the electronic corona device 1 further includes means for processing and displaying the data output from the sensor 304. Including, the calculation circuit 11 200909776 401, the memory 402, the input (date and time latitude and longitude) device 4〇3, the display screen 404 and the subtractor 405 are four parts. The calculation circuit 4〇1 may be a single chip microcomputer, such as a microprocessor controller (MCU) or a dedicated integrated circuit (ASIC), for storing an equation for calculating an inherent day angle Θ. The inherent daylight angle θ is finally obtained. The date, time, and latitude and longitude information of the measurement point are calculated by the input device 403 into the equation; the memory 4〇2 can be electrically erasable and programmable. Selling memory (EEPROM), or fixed memory (n〇nv〇latile memory), used to store the information of the time, time and latitude and longitude of the time zone; the wheel device 403 can be input for the button; the display can be The liquid crystal display curtain; as shown in FIG. 4, the input device thoroughly inputs the date, time, and latitude and longitude information into the memory 402, and the memory 4〇2 inputs the above information into the calculation circuit 4〇1 to obtain the inherent day angle θ ' The angle difference φ between the measurement point and the shadow read by the sensor and the sensor is input to the subtracter 4〇5, and the true azimuth angle α′ is outputted on the display screen 4G4, and the screen side is displayed by selecting alone. It is also possible to display the #information and the intrinsic day angle 0 stored in the memory 402. The device is powered by low voltage direct current, preferably 9-12 VDC, and the entire circuit arrangement is controlled by a switch. Alternatively, the present invention can also obtain local information by using a general GPS positioning system injury, and then obtain the local latitude and longitude by the look-up table method, and have a diurnal angle by giving the time of the 疋. The advantage of using the Gps line is that when using the electronic day-of-the-day compass device, the user can automatically obtain the latitude and longitude information without having to wheel in by himself. In order to make the test effect more accurate, the electronic turbulence compass device 1 provided by the present invention can also selectively increase the calibration device: including, the level 12 200909776 113 'placed on the surface of the electronic corona device 1' is preferably a bubble level By observing the position of the bubble, determining whether the compass device 1 is placed horizontally; the turntable fine-tuning control wheel 114 is placed at any position on the surface of the compass device except the bottom surface, and is connected with the main rotating shaft 204, as described above due to the synchronous rotation 5 The turntable 203 and the positioning pin 1〇1 rotate with less the main rotating shaft 204. Therefore, the fine adjustment control wheel 114 can rotate the same rotating disk 2〇3 and the positioning pin 101 by a small angle by controlling the main rotating shaft 204. Any of the levels and fine-tuning control wheels of the prior art can be used to achieve the above functions; less than two electronic distance measurement (not metered out), such as ultrasonic ranging 10 instrument, infrared range finder, placed in electronics The surface of the cymbal disk device 1 is used to measure the distance of the compass device 1 to the surface of the object when measuring the position of the object at a relatively close distance, thereby ensuring that the reference edge II6' is as shown in Fig. 6, and the object to be measured ( For example a work frame) parallel. Fig. 5, Fig. 6 shows the operation of the electronic cymbal device 1 15 of the present invention for use in sufficient sunlight. In step 5〇1, a certain position on the surface of the compass 1 is marked as a measuring point 115. For an object measuring a far distance, such as a building, the user faces the measuring point 115 of the compass device 1 to be measured. The object 601, for measuring objects closer to the distance, the user can use the information of the electronic range finder to keep the reference side 116 of the compass device and the object to be measured, such as a decoration, parallel; less than 502, using the level 113 The position of the compass device 1 is corrected to be horizontal, and the positioning pin 1〇1 is turned to the measuring point 115. The purpose of this step is to determine the position of the measured object, so that the sensor 304 senses an initial value; and in step 503, the rotating positioning pin 1 〇1, the sharp end 103 is directed to the sun shadow projected by the sundial needle 102 in the sun; step 504' adjusts the fine adjustment 13 200909776 control wheel 114 so that the sharp end 103 of the positioning pin 101 and the colored straight line 107 and the sundial needle 102 are in the sun The next projected day shadows coincide, and the purpose of steps 503 and 504 is to cause sensor 304 to sense an end value that is compared to the initial value of step 502 to enable sensor 304 to obtain the measured value. The angle difference φ between the body and the day shadow is 5; in step 505, the sensor 304 reads the angle difference φ between the day shadow and the measuring point 115. As described above, the angle φ is the sunshade natural angle 0 and the measurement The angle α of the point itself, that is, the difference between the measured azimuth angles, that is, φ=θ-α, requires the next step to obtain the measured azimuth angle α; Step 506, the calculation circuit 401 is started, and the memory is The date, time, and the time zone latitude and longitude data of the time zone of 402 are input into the calculation circuit 401 or the latitude and longitude information is determined by the GPS positioning system, and the local inherent shadow angle 0 is calculated, and finally the above equation is calculated by shifting the item to obtain the measured The azimuth angle α = θ_φ.
