[0061] The application scenarios of the present application are mainly based on wireless communication equipment, and can also be applied to other scenarios according to its functions. Its application scenarios are not restricted or limited by the specific embodiments recorded in this application.

[0062] Second, existing network communication equipment, outdoor cameras and other equipment often face problems with limited power supply and signal transmission when used outdoors. Existing solutions usually rely on dedicated network transformers and power converters. Although these devices solve the problems of power supply and signal transmission to a certain extent, they often have limitations such as high cost, poor flexibility, and difficult maintenance. Especially in scenarios where multiple voltage outputs and wide-range voltage inputs need to be supported, traditional equipment often cannot meet the requirements, resulting in limited equipment use and low overall system efficiency.

[0063] Based on the above problems, the present invention particularly provides a technical solution to solve the above problems. The technical solution, working principle and technical effects of the present invention are described in detail below in conjunction with specific embodiments.

[0064] Reference Figure 1 The multi-mode output voltage and network signal separation transmission device of the present invention includes a signal and power conversion module, a network signal transmission module, and an output control module. The modules are electrically connected to each other for circuit connection or communication.

[0074] When working, the MCU unit detects the output current through the built-in ADC (analog-to-digital converter) and determines the current load condition according to the preset algorithm. Then the MCU unit outputs the control signal to the multi-way selection logic switch through the GPIO. The logic switch controls the multi-way selection logic switch through the GPIO output according to the output current detected by the MCU, and outputs 36V, 48V, and 56V DC voltages.
