The core of the present invention is to provide a method for testing an ac power switch, wherein a flow diagram of a specific embodiment is shown in fig. 1, which is referred to as a first specific embodiment and includes:
s101: and acquiring power supply current information.
The power supply current information can be obtained through a monitoring component arranged in the electrical appliance to be tested, can also be obtained through a power supply for supplying power to the electrical appliance to be tested, and of course, other obtaining methods can also be selected according to actual conditions, wherein the power supply current information is information reflecting the current magnitude.
S102: and when the time length of the power supply current information exceeding the action current threshold value in the first time length does not exceed the error time length threshold value, disconnecting the power supply of the electrical appliance to be tested.
And an instantaneous current value can be obtained at intervals of a certain time by a point obtaining measurement method, and after the continuous value reaches the first time, if the number of points exceeding the action current threshold does not exceed the error time threshold, the electric appliance to be tested is judged to be in a power-on and power-off state at the moment, and power can be cut off. Of course, other methods for determining whether the time length during which the supply current information exceeds the action current threshold in the first time length exceeds the error time length threshold may be selected according to actual conditions.
The existence of the error duration threshold value enables the alternating current power switch testing method provided by the invention to have a certain fault tolerance rate for judging whether the electrical appliance to be tested is in the power-on and power-off state, namely due to the influence of the circuit environment, after the electrical appliance to be tested is powered off, interference signals still exist to enable the power supply current information to exceed the action current threshold value.
In addition, the error duration threshold may be zero, that is, the supply current information does not always exceed the action current threshold in the first duration, and of course, other error duration thresholds may also be set according to actual needs.
S103: and when the time length for disconnecting the power supply of the electrical appliance to be tested reaches a second time length, switching on the power supply of the electrical appliance to be tested.
This step follows step S102, and starts timing after power off, and when the preset second duration is reached, the power supply of the electrical appliance to be tested can be turned on again, and the electrical appliance to be tested can be turned on again.
S104: and acquiring the starting information of the electric appliance to be tested after the power supply is switched on.

On the basis of the second specific embodiment, in order to solve the problem that the processing of the test result by the relevant person may not be timely, the determination condition for disconnecting the power supply of the electrical appliance to be tested is further defined, and a third specific embodiment is obtained, where a flow diagram is shown in fig. 3, and includes:

the starting information acquisition module is used for acquiring the starting information of the electric appliance to be tested after the power supply is switched on;
and the result determining module is used for obtaining the testing information of the alternating current power switch according to the starting information.
5. The ac power switch testing apparatus of claim 4, wherein said current monitoring module further comprises:
and the accurate judgment unit is used for disconnecting the power supply of the electrical appliance to be tested when the power supply current information does not exceed the action current threshold value in the first time period.
6. The ac power switch testing apparatus of claim 4, wherein said result determining module further comprises:
the error reporting judgment unit is used for judging whether the test information of the alternating current power supply switch comprises error reporting information or not;
and the alarm unit is used for sending an alarm signal when the error information is included.
7. An alternating current power switch test apparatus, comprising:
a memory for storing a computer program;
a processor for implementing the steps of the ac power switch testing method of any one of claims 1 to 3 when executing said computer program.
8. A computer-readable storage medium, having stored thereon a computer program which, when executed by a processor, carries out the steps of the ac power switch testing method of any one of claims 1 to 3.
9. An AC power switch is characterized by comprising a current relay and a time relay;
the current relay is used for monitoring the power supply current information of the alternating current power supply switch to the electric appliance to be tested; when the time length of the power supply current information exceeding the action current threshold value in the first time length does not exceed the error time length threshold value, disconnecting the power supply of the electric appliance to be tested;
and the time relay is used for switching on the power supply of the electric appliance to be tested when the time length for switching off the electric appliance to be tested reaches a second time length, so that the electric appliance to be tested generates power-on information, and the test information of the alternating current power supply switch corresponding to the electric appliance to be tested is obtained through the power-on information.
10. The ac power switch of claim 9, further comprising an alarm processor;
the alarm processor is used for judging whether the test information of the alternating current power supply switch comprises an error signal;
when the error information is included, an alarm signal is transmitted.
