In the prior art, when detecting the ground coil module, mostly the manual inspection is performed, but because the ground coil modules are more in quantity and the same in appearance, the failed ground coil module cannot be found in time only by the manual inspection. Therefore, a system and a method for monitoring the whole life cycle of the ground coil module are needed to monitor the health condition of the ground coil module and find out the fault in time.
To address the above issues, embodiments herein provide a system for ground coil module fault monitoring. Fig. 1 is a schematic structural diagram of a system for ground coil module fault monitoring provided in an embodiment of the present disclosure.
Referring to fig. 1, a system for ground coil module fault monitoring includes:
the plurality of acquisition devices 100 are used for acquiring the state information of the plurality of ground coil modules in real time;
an analysis apparatus 400 for:
acquiring state information of a plurality of ground coil modules;

and determining the fault condition of the target ground coil module according to the analysis result of the target ground coil module.
After the state information of the target ground coil module is acquired through the analysis device 400, the state information of the target ground coil module and the ground coil module adjacent to the target ground coil module in a specified time period is compared, and/or the state information of the target ground coil module and the specific historical state information of the target ground coil module are compared, so that the analysis result of the target ground coil module can be obtained, and the fault condition of the target ground coil module can be determined according to the obtained analysis result.

the sensing module collects the state information of the ground coil module in real time and transmits the state information of the ground coil module to the control module;
the control module acquires the state information of the ground coil module and transmits the state information of the ground coil module in real time through the wireless transmission module.
Further, the sensing module comprises a temperature sensor, a humidity sensor and a hall sensor, wherein the temperature sensor and the humidity sensor are respectively used for detecting the ambient temperature and the ambient humidity of the ground coil module, and the hall sensor is used for detecting the magnetic field intensity of the ground coil module. Specifically, the fault condition of the ground coil module can be judged through the magnetic field intensity, and therefore the magnetic field intensity of the ground coil module, which is acquired through the Hall sensor, can be used as the state information of the ground coil module. Because ambient temperature and humidity can influence the magnetic field intensity of ground coil module, consequently need temperature sensor and humidity transducer real-time detection ambient temperature and humidity condition, as the environmental basis of ground coil module when carrying out failure diagnosis.
In some embodiments, comparing the state information of the target ground coil module and the ground coil modules adjacent to the target ground coil module within a specified time period to obtain an analysis result of the target ground coil module includes:
determining the average value, the maximum value, the minimum value and the correlation coefficient of the state information of the target ground coil module in the specified time period;

and comparing the average value, the maximum value, the minimum value and the correlation coefficient of the state information of the target ground coil module with the average value, the maximum value, the minimum value and the correlation coefficient of the state information of the adjacent ground coil module to obtain a first comparison result of the target ground coil module.
Specifically, when performing the comparison, the analysis device 400 may acquire the state information once every set time interval for the target ground coil module that needs to be subjected to the fault determination, and may acquire a plurality of state information in a specified time period. For example, the state information may be acquired every 10 minutes, and 6 pieces of state information may be acquired in an hour from 8 to 9 points on a certain day, and for the 6 pieces of state information, the average value, the maximum value, the minimum value, and the correlation coefficient are obtained. For the ground coil module adjacent to the ground coil module, state information is acquired at set time intervals within a specified time period, namely the state information is acquired at 8 to 9 points on the same day at intervals of 10 minutes, and the average value, the maximum value, the minimum value and the correlation coefficient are also calculated for the 6 pieces of state information. Because the ambient temperature and the humidity of two adjacent ground coil modules are close, consequently need select adjacent ground coil module as the contrast when carrying out the contrast to reduce ambient temperature and humidity to magnetic field intensity's influence, ensure the degree of accuracy of contrast result.
Further, the comparing the average value, the maximum value, the minimum value and the correlation coefficient of the state information of the target ground coil module with the average value, the maximum value, the minimum value and the correlation coefficient of the state information of the ground coil module adjacent to the target ground coil module to obtain a first comparison result of the target ground coil module includes:

Specifically, the current state information of the target ground coil module is state information in a selected time period collected in real time, for example, the current state information is obtained every 10 minutes from 8 to 9 points a day, and the obtained 6 pieces of state information are the current state information of the target ground coil module. The specific historical state information is selected historical state information of the target ground coil module in a certain day, and specifically may be state information in a selected time period after the target ground coil module is initially installed, for example, state information is acquired every 10 minutes at 8 to 9 points in the historical day, and the 6 pieces of acquired state information are the specific historical state information of the target ground coil module. Because the ground coil module just put into use relatively at this moment, the performance of each side is better, and the parameter is more accurate, and the fault degree is low. The selection of the history in one day can be based on the following method: the temperature and the humidity which are similar to the temperature and the humidity of the target ground coil module in the current day and the temperature and the humidity which are similar to the temperature and the humidity in the history after the target ground coil module is initially installed in the current day can be selected, the temperature difference value between the temperature in the history certain day and the temperature in the current day is within the range of 0-5 ℃, and the humidity difference value between the humidity in the history certain day and the humidity in the current day is within 50% RH, so that the accuracy of the comparison result is ensured.
Specifically, in the comparison, in the current environment, for the target ground coil module, the analysis device 400 may obtain an average value, a maximum value, a minimum value, and a correlation coefficient for 6 pieces of state information obtained in the current day within the hour from 8 points to 9 points. The average value, the maximum value, the minimum value and the correlation coefficient are also calculated for 6 state information within the hour from 8 to 9 acquired on a certain day in history.
