Problems solved by technology
[0003] 1. The device is directly connected to the strong power grid, and the electrical safety problem is not easy to fundamentally solve;
[0004] 2. Since this type of device needs to be directly coupled with the strong power grid, it cannot be directly integrated with other communication equipment powered by low-voltage weak current, which greatly limits the application range of power line carrier communication;
[0005] 3. Since the power line carrier signal cannot pass through the commonly used power adapter, even if this type of device is integrated with other low-voltage communication equipment in the same device, it cannot share the same power system, which increases the cost of equipment;
[0006] 4. Since the circuit that converts strong electricity into weak electricity is in the same device as the signal processing system, it is difficult for such devices to be small in size, and it is difficult to become a real portable communication device

Description
technical field [0001] The invention belongs to a power line carrier communication terminal device. Background technique [0002] In the design of power line carrier communication terminal devices, the usual method is to place all electronic circuits, including power processing circuits and signal processing circuits, in the same device, which is directly connected to the 220V or 110V The device connects the Ethernet communication signal of the network equipment to the 220V or 110V strong power grid to achieve the purpose of broadband network communication through the strong power grid. Such devices not only load communication signals from the strong power grid, but also obtain power supply from the strong power grid. Such as figure 1 As shown, the strong current power grid is divided into two routes after the strong current protection circuit, and one route is directly connected to the carrier signal coupling transformer T1, so that the carrier signal on the strong curren...
