Problems solved by technology
[0003] The power supply of the carrier module is provided by the smart meter, which continuously provides 5V and 12V power for the carrier module through the connecting pins. Due to the limitation of the power supply, when the carrier module sends low-frequency carrier signals, it is often caused by insufficient power provided by the smart meter. The carrier signal cannot be completely sent to the power line, resulting in communication failure, or the problem of smart meter reset due to insufficient power supply

Embodiments of the present application provide a power carrier amplifier circuit and a power system, which relate to the technical field of power carrier waves, and include a carrier amplifier, an energy storage, a current monitor, a signal control switch, and a controller. The output end of the electric energy storage is electrically connected with the input end of the signal control switch, the output end of the signal control switch is electrically connected with the input end of the carrier amplifier, and the control end of the signal control switch is electrically connected with the controller. One end of the current monitor is electrically connected to the output end of the carrier amplifier, and the other end is electrically connected to the controller. The current value of the carrier amplifier is collected by the current monitor. When the controller determines that the current value is less than the preset threshold value, it sends a control signal to the signal control switch, so that the energy storage device can charge the carrier amplifier. Insufficient, the carrier signal of the carrier amplifier cannot be completely sent to the power line, thus causing the problem of communication failure.
Description
technical field [0001] The present application relates to the field of power carrier technology, and in particular, to a power carrier amplifier circuit and a power system. Background technique [0002] The smart meter carrier module is a key component of the power carrier communication system, and is the end node and communication relay node of the power carrier communication system. Due to the huge number of carrier modules, its communication quality determines the communication quality of the entire communication system. Therefore, the carrier module design appears to be crucial. [0003] The power supply of the carrier module is provided by the smart meter. The smart meter continuously provides 5V and 12V power to the carrier module through the connecting pins. Due to the limitation of the power supply, when the carrier module sends a low-frequency carrier signal, it is often caused by insufficient power provided by the smart meter. The carrier signal cannot be complete...
