Unattended power supply system of sensor

Abstract

The invention relates to an unattended power supply system of a sensor, and belongs to the power field of an independent power supply. The system comprises a solar photovoltaic power generation assembly and a fuel cell stack. A water storage settling pond is arranged in the system, and a water purifying device is arranged behind the water storage settling pond. Purified water enters a purified water tank, and water for electrolytic hydrogen making by an electrolytic cell is from the purified water tank. A hydrogen storage tank for operation of the fuel cell stack is arranged behind the electrolytic cell, and an outlet water recovery pipe is arranged on the fuel cell stack and connected to the purified water tank. The system is provided with a controller for centralized control of the solar photovoltaic power generation assembly, the fuel cell stack, the water purifying device and the electrolytic cell. The system provided with corresponding detecting and automatic controller devices can completely realize automation, the power generation efficiency of the system is high, and the system can be integrally arranged in remote independent power supply monitoring areas.

Description

technical field [0001] The invention relates to an unattended system, in particular to an unattended sensor power supply system, which belongs to the field of independent electric power supply. Background technique [0002] With the development of power automation and informatization, remote monitoring of power systems has become more and more important. Because power transmission has large areas, wide distribution, large network spans, and many places with steep terrain, it even has to go through many unmanned In modern technology, the monitoring of these systems often relies on sensors to transmit information remotely. A stable power supply system is the prerequisite for reliable operation of sensors. Power transmission is often high-voltage power, which cannot be directly used to provide working power for sensors. In the past, people The various power storage devices developed such as batteries can only provide power to the system within a certain period of time. The comb...

[0002] With the development of power automation and informatization, remote monitoring of power systems has become more and more important. Because power transmission has large areas, wide distribution, large network spans, and many places with steep terrain, it even has to go through many unmanned In modern technology, the monitoring of these systems often relies on sensors to transmit information remotely. A stable power supply system is the prerequisite for reliable operation of sensors. Power transmission is often high-voltage power, which cannot be directly used to provide working power for sensors. In the past, people The various power storage devices developed such as batteries can only provide power to the system within a certain period of time. The combined system of photovoltaic power generation modules and batteries can realize self-supply of electricity, but on the one hand, the price of batteries is too high, on the other hand, due to the geographical location of the power system A large part of the environment is relatively harsh, which not only increases the aging speed of the battery, but also causes great uncertainty to the system. The combination of photovoltaics and fuel cells provides another option, but this system often requires human resources. Regular observation and artificial water addition increase the workload and tediousness
