In general, a-48V communication power supply system includes a power supply monitoring unit, a power supply unit, and the like, wherein an important function of the power supply monitoring unit is to collect various signals, such as voltage, temperature, and the like, of components in the communication power supply system, so that the power supply monitoring unit can effectively control the components. The power supply unit is used for supplying power to all components and loads of the power supply monitoring unit.
After the power supply monitoring unit receives the current signal and the voltage signal which are generated by each component and take-48V as reference ground, the signal processing module and the analog/digital conversion module of the power supply monitoring unit are required to further process the signals, such as amplifying, converting an analog signal into a digital signal and the like. The signal processing module and the analog/digital conversion module are generally referred to as a signal acquisition module.
The power supply monitoring unit further comprises a communication module for realizing communication with the docking device. The communication bus of the communication module is RS485, RS232, CAN or I2C; the docking device is typically a main control board, a user device communication port, etc., which is referenced to ground (0V). In order to ensure the compatibility of the communication module with the docking device, the reference ground of the communication module also needs to select 0V.
Since a 48V voltage difference exists between the reference ground of the communication module and the-48V bus, the reference grounds of the communication module and the-48V bus need to be isolated when the circuit is deployed so as to ensure the normal operation of the communication module and the-48V bus. Because each communication bus of the communication module needs to be connected with the CPU, each communication bus needs to be isolated by a separate isolation circuit, and when the communication module comprises a plurality of communication buses, the needed isolation circuits are more, the isolation cost is high, the circuit is complex, and the radiation is high.
