Conventional feeder automation terminal FTU device power is taken from a PT device installed on a high voltage line. The PT device belongs to primary equipment and is used for changing 10 KV high-voltage power supply into 220V low-voltage power supply to supply power to FTU. The equipment has heavy weight and is inconvenient to transport and install, and particularly, accidents such as damage and explosion of the PT device are caused by frequent occurrence of resonance and the like, so that new fault hidden danger is caused to a power grid. The conventional FTU can only be powered in this way because the conventional FTU consumes a large amount of power. The power consumption of the feeder line terminal mainly comprises a communication part, an acquisition part, a switch and indicator light part and the self power consumption of a chip. The main station and the FTU are communicated with each other mainly through the total calling of the main station, the substation detects that the telemetering information is abnormal or the telemetering deflection event is actively reported, and the communication module is in standby state in the rest time, so that energy is wasted. The overall power consumption of a general FTU terminal is about dozens of watts, and the loss is unacceptable from the aspects of energy source and economy. And the power consumption of the equipment is reduced to 2W from dozens of watts through an ultra-low power consumption technology, so that the consumption and the energy are greatly reduced. The operation load of the current voltage transformer PT/CT can be reduced, the service life of related equipment is prolonged, the upgrading and updating of primary equipment such as a traditional power distribution switch and the PT/CT can be promoted, and the maintenance cost is reduced.

The DLT 634.5-101-based low power consumption wireless communication system as claimed in claim 3, wherein the host system active wake-up wireless communication unit mechanism is that when the host system collects the telemetry signal deflection, the event record with time scale and the telemetry value exceeding the dead zone range through the data collection layer, it will actively send the data frame to the master station, and the host system will wake-up the wireless communication unit to send the data frame to the master station for reporting; when the communication link is abnormal, in order to reduce power consumption, if the terminal is abnormal, the terminal does not respond to the heartbeat packet sent by the master station; if the master station is abnormal, the wireless module sends a link request to the master station at regular time, informs the event processing layer through the wireless communication layer, does not actively send data to the wireless communication module until the link communication is recovered to be normal, and informs the hardware processing layer to close the corresponding serial port peripheral to enter a hardware low power consumption mode.
7. The DLT 634.5-101-based low power consumption wireless communication system as claimed in claim 1, wherein the hardware circuit of the host system layer is designed with low power consumption, the core MCU chip is STM32L series, and the LDO chip is high-efficiency IC chip and meets the power output requirement.
8. The DLT 634.5-101-standard-based low-power-consumption wireless communication system as claimed in claim 1, wherein the data acquisition layer can acquire telemetric data or remote signaling data, the telemetric data is voltage and current data, and the remote signaling is the input amount of telecontrol communication data and the change of various binary signals.
9. The DLT 634.5-101-based low power consumption wireless communication system as claimed in claim 2, wherein the power supply system unit is provided with a power supply chip, and the power supply detection unit is provided with a voltage monitoring chip to ensure efficient and stable operation of the system power supply part.
