Claim 0:
1. A power switch circuit, wherein the power switch circuit comprises a solar photovoltaic panel, a detection circuit, and a switch circuit:
wherein the detection circuit comprises a first switch module and a power detection module, a first terminal of the first switch module is connected with the solar photovoltaic panel and the switch circuit respectively, a second terminal of the first switch module is connected with a third terminal of the power detection module, and a third terminal of the first switch module is used for grounding;
wherein the first terminal of the first switch module is a control terminal; a first terminal of the power detection module is connected with the solar photovoltaic panel, a second terminal of the power detection module is connected with the switch circuit and the solar photovoltaic panel is connected with a load through the switch circuit;
wherein the solar photovoltaic panel is configured to output an electrical signal to control the first switch module to be turned on;
when the first switch module is turned on, the power detection module enters a working state to detect the power in the electrical signal;
when the power in the electrical signal detected by the power detection module is greater than the preset threshold, the power detection module outputs a first control signal to the switch circuit to turn on the switch circuit; when the switch circuit is turned on, the solar photovoltaic panel supplying power to the load through the switch circuit and the switch circuit feeds back the second control signal to the first terminal of the first switch module to turn off the first switch module; when the firs switch module is turned off, the detection circuit stops working.
