Power-off reset system applied to electronic equipment

Abstract

The invention discloses a power-off reset system applied to electronic equipment, which comprises a current detection module, a relay module and a processor module, wherein the current detection module is connected with a power supply and used for detecting the power supply current of the power supply to the electronic equipment; the input end of the relay module is connected with the current detection module, the output end is connected with the electronic equipment, and the relay module is used for controlling the turn-on or turn-off of the power supply to the electronic equipment; and the processor module is connected with the current detection module and the relay module, the processor module acquires a current value detected by the current detection module, judges whether the operation of the electronic equipment is abnormal or not according to the current value, and sends a power-off reset signal to the relay module if the operation is abnormal so as to enable the electronic equipment to be subjected to power-off reset. The system can performs power-off reset on the electronic equipment in a forcible manner when the electronic equipment breaks down so as to enable the electronic equipment to be in a normal working state again.

Description

technical field [0001] The invention relates to the field of electronic equipment detection. More specifically, the present invention relates to a power-off reset system applied to electronic equipment. Background technique [0002] In engineering applications, a large number of electronic devices that need to run for a long time are often subject to some interference from the outside world, or there are some inherent defects in the device itself, etc. These situations often cause the processor program in the electronic device to run away and enter an endless loop At this time, relying on the original device's own instruction technology and software trap technology cannot make the out-of-control program get rid of the dilemma of an infinite loop, the processor will fall into a stagnation state and will not automatically return to a controllable working state, and the system will be completely paralyzed. At this time, if the operator is present, he can press the manual reset...

[0002] In engineering applications, a large number of electronic devices that need to run for a long time are often subject to some interference from the outside world, or there are some inherent defects in the device itself, etc. These situations often cause the processor program in the electronic device to run away and enter an endless loop At this time, relying on the original device's own instruction technology and software trap technology cannot make the out-of-control program get rid of the dilemma of an infinite loop, the processor will fall into a stagnation state and will not automatically return to a controllable working state, and the system will be completely paralyzed

At this time, if the operator is present, he can press the manual reset button or power on the device again to force the system to resume normal operation through reset. However, in actual engineering applications, the operator cannot monitor the system operation at any time. Manual reduction after adverse outcome
