Wind/solar/electricity complementary power supply system for urban road monitoring device

Abstract

The invention discloses a wind / solar / electricity complementary power supply system for an urban road monitoring device. In a condition of mains power supply, a photovoltaic module, a wind power generator and a battery are additionally arranged, and an electrical control part formed by a high-frequency switching power supply, a wind / solar complementary controller, an off-grid inverter, an AC distribution unit and a DC distribution unit is configured between the power supplies and an AC load and a DC load in the monitoring device. The multiple power supplies in the system are different in power generation forms and strong in complementarity, and normal operation of the urban monitoring device in the area can be realized in extreme harsh weather or during a period of power failure of a certain power device. During the system operation period, the photovoltaic energy and the wind energy are used in preference, and the mains supply serves as emergency backup energy for the above two kinds of new energy. The prepared battery serves as temporary substitute energy when other power devices fail to operate. Multiple power supply operation modes are adopted, economic profits and environmental protection can be achieved, the operation reliability is high, and the system is particularly matched for use in main urban roads or important places.

Description

technical field [0001] The present invention relates to a power supply system. Specifically, the present invention relates to a power supply system for an urban road monitoring device, in particular to a wind and electricity complementary power supply system for an urban road monitoring device. Background technique [0002] Roads are one of the infrastructures of cities. The criss-crossing roads facilitate the orderly flow of people and the orderly driving of vehicles. In today's era, in order to strengthen the traffic order management and public security management of urban roads, monitoring devices are arranged at major roads and important nodes in the city. The dense and connected monitoring devices constitute the urban road monitoring system. The network monitoring system is conducive to the centralized management and control of urban traffic order by functional departments, and is also conducive to public security monitoring. The existing digital monitoring system can...

Problems solved by technology

However, the urban road monitoring system has a large application area and many distribution points, and it is placed in the open air. It is difficult to ensure uninterrupted power supply when it is equipped with a single mains power supply. Once a traffic accident or public security case occurs during the period, there is no relevant on-site video information

This situation does not meet the requirements of the city monitoring system for all-weather, uninterrupted operation
