Problems solved by technology

The disadvantages of this type of supply voltage monitoring control device are:
[0003] 1. There are too few channels, only one or two signals can be monitored
[0004] 2. It can only roughly judge the abnormality of the power supply, but cannot monitor the power supply change accurately and in real time
[0005] 3. Only limited control functions are provided, generally reset signals, no drive capability and few channels
[0008] 2. It does not have the communication function with the upper computer, and the display mode cannot be changed after installation
[0009] 3. Few channels, only one or two channels

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 ...
