Problems solved by technology
[0007] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a remote wireless control system and method for the rainwater pump room, which is used to solve the problem of If the drainage system is not opened in time during the rainstorm, the rainwater will pour into the pump room, causing water to enter the electrical equipment, causing the pump to trip, affecting the external water supply, and the rainwater pump room needs to be opened urgently. The box is very easy to make rainwater enter the local control cabinet, causing safety hazards

The invention provides a rainwater pump room remote wireless control system comprising a first control unit which outputs a rainwater pump start or stop instruction, a master wireless unit which receives the rainwater pump start or stop instruction, encodes the rainwater pump start or stop instruction into a start or stop carrier signal and modulates the carrier signal into a start or stop frequency-modulated signal, a slave wireless unit which converts the start or stop frequency-modulated signal into a start or stop carrier signal and decodes the start or stop carrier signal into a rainwater pump start or stop signal, and a second control unit which controls start or stop of a rainwater pump according to the rainwater pump start or stop signal output by the slave wireless unit, and transmits a rainwater pump turned-on / off signal to the first control unit from the slave wireless unit and the main wireless unit. By adopting the system, the security hidden danger in outdoor operation of workers under heavy rain or other bad weather conditions is eliminated. Remote liquid level alarm ensures that the ultra-limit state of the liquid level can be displayed in real time. The remote wireless control mode improves the timeliness and necessity of rainwater pump start and stop.
Description
technical field [0001] The invention relates to the technical field of safety of an urban water supply system, to a control system, in particular to a remote wireless control system for a rainwater pump house. Background technique [0002] Water is an indispensable material condition for the formation and development of cities. The earliest human settlements occurred near natural bodies of water. The water demand of modern cities is much greater than that of ancient cities, so the water supply system must have special planning. In 1879, China's first modern water supply project was completed in Lushun. Since then, Shanghai and other cities have successively built water supply engineering facilities. In 1949, there were 73 cities, counties and towns in China with public water supply facilities, and the annual water supply was 430 million cubic meters. In 1983, according to the statistics of 253 cities, the annual water supply of public water supply facilities reached 10.6...
