Description

technical field

[0001] The invention belongs to the technical field of electronic detection, and relates to a power monitoring device, in particular to a programmable multi-channel power monitoring module based on an MSP430 single-chip microcomputer. technical background

[0002] At present, there are many monitoring and control devices for power supply voltage on the market, which can generate a reset signal when the power supply is cut off or the voltage drops instantaneously; The disadvantages of this type of supply voltage monitoring control device are:

[0003] 1. There are too few channels, and only one or two signals can be monitored.

[0004] 2. It can only roughly judge the abnormality of the power supply, but cannot accurately and real-time monitor the change of the power supply.

[0005] 3. It only provides limited control functions, usually a reset signal, does not have drive capability and has few channels.

[0006] In addition, there are display modules for ...
