Specifically, after the user terminal 100 establishes a connection with the electroscope 200, the visual operation interface displays a self-checking button, and the user terminal 100 receives an operation of the self-checking button by a user and sends a self-checking command to the electroscope 200.
In step S180, after receiving the self-checking command, the electroscope 200 detects its own running state and sends the detected self-checking data to the user terminal 100.
Specifically, the detecting the self-running state of the electricity testing device 200 may include, but is not limited to, battery power, startup times, working conditions of various components of the device, and the like. The electricity test device 200 transmits the self-test data to the user terminal 100.
In step S190, the user terminal 100 receives and stores the self-checking data, and determines whether the self-checking data is normal or not.
If the self-checking data does not meet the requirement, such as too low battery power or abnormal operation of a certain component, the user terminal 100 displays an identification prompting self-checking failure on the visual interface. And the ranging button is deactivated, e.g., set to gray (i.e., not selectable).
If the self-checking data meets the requirement, the user terminal 100 displays an identifier for prompting the self-checking to pass on the visual interface, and enables the ranging button to be effective.
In this embodiment, the method may further include the following steps.
The user terminal 100 displays device information corresponding to the electroscope 200 according to a user operation.
Specifically, the visual interface further displays a device information button, and the user terminal 100 displays the device information of the electroscope 200 currently connected to the user terminal 100 according to the user's operation of the device information button. The device information comprises factory time, latest verification time and next verification time. Thus, the user can intuitively understand the device information corresponding to the electroscope 200, and the periodic maintenance and calibration of the electroscope 200 are facilitated.
In this embodiment, the method may further include the following steps.
The user terminal 100 displays the electricity test record corresponding to the electricity test device 200 according to the user operation, wherein the electricity test record includes the history of electricity tests.
Specifically, the visual interface further displays a history button, and the user terminal 100 displays the stored electricity test history according to the operation of the user on the history button.
In summary, according to the method and the device for testing electricity in the far field region provided by the application, through the data connection between the electricity testing device 200 and the user terminal 100, the user can conveniently issue the electricity testing instruction to the electricity testing device 200 from the user terminal 100, and can intuitively obtain the electricity testing result through the user terminal 100.
