Abstract

The invention provides a power loss control device of a full-aperture power generation data collecting system. The power loss control device comprises an alternating power loss voltage support circuit, an alternating power loss monitoring loop, a power generation data collecting module, a signal processing module and a signal sending module. The alternating power loss voltage support circuit comprises an alternating-current output end, a switch power supply, a direct-current output end, a super-capacitor module and a direct-current controller. The alternating-current output end is connected with the direct-current output end through the switch power supply. The super-capacitor module is connected with the direct-current output end through the direct-current controller. The alternating-current output end outputs the alternating current to supply power. The direct-current output end outputs the voltage stabilizing direct current to supply power. The alternating power loss monitoring loop comprises an intermediate relay internally provided with a coil and a contact. The coil is connected with the alternating-current output end. The contact is connected with the signal processing module. The power generation data collecting module is connected with the signal processing module. The signal processing module is connected with the signal sending module. By the use of the power loss control device, relayed power supply is achieved.

Description

technical field [0001] The invention relates to the technical field of power generation data acquisition, in particular to a power failure control device for a full-caliber power generation data acquisition system. Background technique [0002] The existing STDA2000 full-caliber power generation data acquisition module, using Beidou satellite transmission technology, performs data monitoring and centralized transmission processing on a large number of small power plants in remote areas, providing a stable and reliable solution for small power plant monitoring that meets the safety requirements of the power industry. Low cost overall solution. However, due to the discontinuity of power supply in small stations, power outages often occur, and the system will stop working at any time due to power failure during use, resulting in the signal receiving end not being able to receive data information, and it is impossible to judge whether it is a communication failure, equipment fai...
