Description

Technical Field

[0001] The utility model relates to the technical field of geomagnetic detectors, in particular to a geomagnetic field measuring device with strong stability. Background Art

[0002] A geomagnetic detector is an instrument used to measure the strength and direction of the earth's magnetic field. It mainly consists of a magnetic sensor and an electronic signal processing system. The working principle of a geomagnetic detector is based on Faraday's law of electromagnetic induction. When the strength or direction of the geomagnetic field changes, it causes an induced electromotive force in the coil in the magnetic sensor. The magnetic sensor transmits the generated electrical signal to the electronic signal processing system for processing. In the electronic signal processing system, the electrical signal generated by the sensor is first amplified and filtered to improve the reliability and accuracy of the signal. Then, a calibration algorithm is used to convert the electrical signal into the actual magnetic field strength and direction values. Finally, the obtained data is transmitted to other devices through an interface for further analysis and application.

[0003] When using an existing geomagnetic detector, a worker is required to hold the instrument and insert a detection rod into the ground to complete the measurement of the magnetic field strength in the area. The worker is required to keep the instrument stable to avoid inaccurate measurement of the detection rod due to shaking of the instrument. However, since geomagnetic detection takes a long time, the worker is required to hold the instrument body for a long time, which is inconvenient for the worker to use. Utility Model Content
