and S101, acquiring specific parameters of the wiring terminal.
In practical applications, the wire connecting terminal can be detected by the related sensor to obtain the specific parameter acquired to the wire connecting terminal by the related sensor. For the related sensors, which may include a voltage sensor, a current sensor, etc., detection is performed when the connection terminal is energized.
In practical application, the operation of connecting the wiring terminal with the wire is that the wire is put into the crimping position of the wiring terminal, the wire terminal is crimped manually, and the wire is crimped and fixed in the wiring terminal, so that the problem that the crimping condition cannot be accurately judged by visual inspection, the conditions of uneven crimping surface and poor contact caused by no good crimping can occur, and the wiring terminal has dangerous hidden danger in the use process of electrical equipment.
And the condition that the wire is crimped by the wire connecting terminal can be reflected through specific parameters of the wire connecting terminal.
In one embodiment, the acquiring specific parameters of the connection terminal includes:

And acquiring the current flowing through the wiring terminal.
In the scheme of the embodiment, two parameters of the voltage and the current of the connecting terminal are used as specific parameters, and the condition that the connecting terminal is in press connection with a wire can be reflected through the voltage and the current.

In one embodiment, the analyzing the contact condition of the connection terminal according to the specific parameter includes:
and analyzing the contact condition of the wiring terminal according to the voltage and the current.
In practical application, when the wire is not well crimped in the wiring terminal, the problem of poor contact may occur, the voltage and the current of the wiring terminal are abnormally changed, and the contact condition of the wiring terminal can be analyzed according to the detected actual voltage and current.

For example, if the wire is crimped by the terminal, if the crimping quality is very good, the actual contact impedance of the terminal is smaller according to the detected actual voltage and current, and correspondingly, the heating power of the contact terminal is smaller; and if the crimping quality of the wiring terminal is not good, the phenomenon of poor contact exists between the wiring terminal and the lead, the actual contact impedance of the wiring terminal is larger according to the detected actual voltage and current, correspondingly, the heating power of the contact terminal is also larger, and under the condition of long-time power, the wiring terminal and the wire at the crimping position can be burnt, even safety accidents such as fire disasters are caused.
