Description of the drawings
Fig. 1 is apparatus of the present invention composition figure；
Wherein：10, Magnetic Sensor, 20, divide CPU, 30, host CPU, 40, display unit, 50, power supply unit, 60, send it is single
Member.
Specific implementation mode
Below by way of specific implementation mode, the invention will be further described.
Referring to Fig.1, a kind of magnetic azimuth detection device, including Magnetic Sensor battle array, display unit 40, power supply unit 50, hair
Send unit 60 and host CPU 30 etc..The Magnetic Sensor battle array includes several Magnetic Sensors 10 and several points of CPU20, several magnetic sensing
Device 10 is uniformly equally spaced on pcb board, i.e. array distribution.Each Magnetic Sensor 10 individually detects sensing data, Magnetic Sensor
10 positions are different, then the data detected in the earth's magnetic field environment being disturbed are different, which is magnetic field intensity.If should
It is dry to divide CPU20 and the 10 one-to-one connection of several Magnetic Sensors, the sensing data detected for identification and sensing data is carried out
Preliminary treatment, it is ensured that data it is accurate.
The host CPU 30 is connected with several points of CPU20, the sensing data for receiving each point of CPU20 transmission such as periodical, into
Row calculates analysis, according to the position of each Magnetic Sensor 10 and data variation rule, extrapolates actual azimuth, eliminates environment pair
The interference of single Magnetic Sensor.
The display unit 40 is connected with host CPU 30, for showing measurement result, including azimuth and is disturbed situation
Deng.The power supply unit 50 is connected with Magnetic Sensor battle array, display unit 40 and host CPU 30, for for each unit provide power supply and
Management.The transmission unit 60 is connected with host CPU 30, and transmission unit 60 receives the information that host CPU 30 is sent, and wirelessly
Launch, is sent remotely to management platform, the information of transmission includes number, site name and the position of measurement result and device
The information such as set.The transmission unit 60 can be WIFI module or mobile communication module.
In practical applications, Magnetic Sensor battle array includes at least three Magnetic Sensors 10 and at least three points of CPU20, such as
