Description

technical field [0001] The invention relates to the technical field of microprocessor power supply voltage monitoring, in particular to a microprocessor power supply voltage monitoring system. Background technique [0002] At present, microprocessors are widely used in transportation, household appliances, industrial equipment, portable equipment, communication equipment, intelligent lighting and urban lighting and many other fields, where they play a core control role and are a veritable "brain" inside. The stable power supply of the microprocessor is the prerequisite and necessary condition for whether it can work stably, and plays a key role in the entire equipment and system. Therefore, in order to ensure the normal and stable operation of the equipment, full attention must be paid to the power supply mode of the microprocessor, real-time monitoring and analysis of the power supply voltage, once a problem is found, timely measures are taken, relevant remedial measures ar...

AI Technical Summary

Problems solved by technology

Once the power supply voltage is abnormal, the microprocessor generally does not work normally or even stops working because it does not detect the power supply voltage in real time, and the microprocessor is completely in a passive working environment.

Although the power supply module is becoming more and more advanced, and the accuracy and reliability are constantly improving, the possibility of system damage or destruction still exists

Of course, some systems have a real-time monitoring system for power supply, such as figure 1 As shown, it is composed of a power supply module, a power supply voltage stabilization module, a power supply voltage monitoring module, a microprocessor, and an output device. The system can dynamically monitor the power supply voltage and issue an alarm once a problem occurs. However, the cost and complexity of the system are relatively high. high
