Network (WIreless-FIdelity, WiFi) module.
Further, communication module 100 is connect with processor 120, and drive module 110 is connect with processor 120.
As shown in fig.2, in the embodiment of the present application, it is as follows to the detailed process of radio frequency interference detection:
Step 200: communication module 100 monitors the network signal of own circumference, and determines the signal quality of network signal
When lower than preset first threshold value, the first notification message is sent to processor 120.
Specifically, when executing step 200, when the signal quality of network signal is lower than preset first threshold value, explanation
The signal quality of network signal is poor, and communication module 100 may receive the interference of radio frequency, in this way, communication module 100
By sending the first notification information to processor 120, processor 120 is notified in time.
Step 210: drive module 110 monitors internal current signal, and determines that the degree of fluctuation of current signal is greater than
When preset second threshold value, second notification message is sent to processor 120.

Current signal inside 110 real-time monitoring of drive module, and according to the fluctuation of calculating of preset period current preset
The average value of current signal in duration, and determine the average value that the average value currently obtained and last calculating obtain
When difference is higher than preset second threshold value, second notification message is sent to processor 120.
For example, it is assumed that the preset period is 30s, when preset fluctuation a length of 2s, preset second threshold value is 10mA, when
The average value of current signal in preceding fluctuation duration (2s) is 50mA, and the current signal in the fluctuation duration (2s) before 30s
