<p>A device and method for detecting a state of a load overcurrent protector are disclosed. The above-mentioned device includes: an input module (22), configured to be connected with two ends of the load overcurrent protector, and generate two output signals respectively at two output ends thereof; a high level signal gating module (24), configured to receive the two output signals generated by the input module (22), and gate and output a high level signal according to the above-mentioned two output signals; a low level signal gating module (26), configured to receive the two output signals generated by the input module (22), and gate and output a low level signal according to the above-mentioned two output signals; and a detecting module (28), configured to detect a voltage difference between the above-mentioned high level signal and the low level signal. Through the technical scheme, the problem that, the state detection of the load overcurrent protector is incompatible with the positive and negative system and requires a software cooperation in the related art, is solved, and then the effectiveness of distinguishing the normal state and abnormal state and realizing compatibility of the positive and negative systems is achieved without the need of participation of the software.</p> |
