[0042] like Figure 1 As shown, an embodiment of the present invention discloses a method for secure access of an electric device, the method comprising:

[0043] Step S101: Acquire multiple electrical parameters of a first device to be connected to a circuit to obtain multiple safety parameters.

[0044] The types of the first devices are different, and the corresponding multiple electrical parameters thereof will also be different. Specifically, a safety parameter table is preset, which is used to find the corresponding relationship between the device and the electrical parameters.

[0045] Step S102: Select a corresponding first circuit access point according to the multiple security parameters.

[0046] According to the requirements of multiple safety parameters, the corresponding first circuit access point is selected, specifically, it can be voltage, current, etc.

[0047] Step S103: Connect the first device to the first circuit access point to perform parameter testing.

[0048] The first device is connected to the first circuit access point, and then the test operation is started.

[0049] Step S104: Calculate multiple electrical parameters of the first device at the first circuit access point to obtain multiple usage parameters.

[0050] A plurality of electrical parameters of the first device at the first circuit access point are calculated, and the plurality of electrical parameters correspond to the plurality of previous safety parameters.

[0051] Step S105: Determine whether each of the multiple usage parameters exceeds a corresponding safety parameter in the multiple safety parameters.

[0052] Compare the usage parameters with the safety parameters accordingly to determine whether the usage parameters exceed the safety parameters.

[0053] Step S106: If not, it is determined that the first circuit access point meets the first device security access condition, and the access and use of the first device at the first circuit access point is reserved.

[0054] If not, it is considered that the first circuit access point meets the safety access condition for the first device, and the first device is used in the first circuit access point for a long time.

[0055] A plurality of electrical parameters of the first device are obtained to obtain a plurality of safety parameters. When the first device is running at the first circuit access point, the plurality of electrical parameters of the first device when running are calculated to obtain a plurality of usage parameters. If each usage parameter does not exceed the corresponding safety parameter, then the first circuit access point satisfies the safety access condition of the first device, and the first device continues to be used in the first circuit access point, thereby solving the problem in the prior art that the electrical device is always used after being connected, which poses a safety hazard.

Then, it is necessary to select the next circuit access point for parameter testing. If, in the test of the second circuit access point, the second circuit access point meets the safety access condition of the first device, the first device is accessed and used in the second circuit access point. If the second circuit access point still does not meet the case access condition of the first device, then the corresponding next circuit access point is selected until the current circuit access point meets the safety access condition of the first device.
