Problems solved by technology

Since each communication bus of the communication module needs to be connected to the CPU, each communication bus needs a separate isolation circuit for isolation. When the communication module contains multiple communication buses, more isolation circuits are required, and the isolation cost is high. complex circuit

The communication power supply system in the embodiments of the present invention includes: a power supply monitor unit and at least one power supply unit, with the power supply monitor unit including a signal processing module, an A / D conversion module, a central processing unit and a communication module and further including an isolation module provided between the A / D conversion module and the central processing unit for isolating the negative electrode bus of the power supply unit from the central processing unit and the communication module, wherein the signal processing module is connected to the A / D conversion module and the central processing unit is connected to the communication module.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication power supply system. Background technique [0002] At present, the communication power supply system with a rated voltage between -36V and 60V is usually referred to as a -48V communication power supply system, that is, the positive pole of the power supply is 0V, and the negative pole is -48V. Generally, the -48V communication power supply system includes a power monitoring unit, a power supply unit, etc. Among them, an important function of the power monitoring unit is to collect various signals of various components in the communication power system, such as voltage, temperature, etc., for power monitoring The unit effectively controls each component. The power supply unit is used to supply power to components and loads of the power monitoring unit. [0003] After the power monitoring unit receives the current signal and voltage signal generated by each component wi...
