Remote monitoring device for water flow

Abstract

The invention relates to a remote monitoring device for water flow, which is mainly controlled by a main control computer. The remote monitoring device is provided with a plurality of terminal cases for sub-control; a GPRS wireless communication transmitter transmits water flow information to realize multi-terminal and long-distance monitoring for the water flow; a dual-shielding control circuit,an ultrasonic flow meter, a water flow sensor, a counting card socket, a sound control alarm, a liquid crystal display, an operating keyboard, an AC / DC transformer and the like are arranged on the terminal case; and the main control computer is controlled by a computer program to calculate and process. The device has the advantages of advanced and reasonable design, compact structure, safety, stability, reliability and accurate and detailed data, realizes remote monitoring and control on the flow of scattered water resources, fills the blank of the technology, is a quite ideal remote monitoring device for the water flow, and also can be used for remote monitoring and control on sites of petroleum, chemical industry, heating, food and the like.

Description

technical field [0001] The invention relates to a remote monitoring device for water flow, which belongs to the technical field of water resource monitoring and management. Background technique [0002] Water is the most important resource for human beings to survive. China is a country short of water. The per capita water resources in China are only a quarter of the world's average level. How to plan, develop, utilize, and Management and protection are very important research topics. [0003] There are many rivers, lakes, reservoirs, and reservoirs on land in our country. The water in these areas provides industrial water, domestic water, agricultural irrigation water, and ecological water. Many water supply projects, water resource monitoring stations, and reservoir diversions have been established in various areas. Pumping stations and irrigation pumping stations, because these stations are distributed in a wide area, management is difficult, and some of the sub-stations...

AI Technical Summary

Problems solved by technology

[0003] There are many rivers, lakes, reservoirs, and reservoirs on land in our country. The water in these areas provides industrial water, domestic water, agricultural irrigation water, and ecological water. Many water supply projects, water resource monitoring stations, and reservoir diversions have been established in various areas. Pumping stations and irrigation pumping stations, because these stations are distributed in a wide area, management is difficult, and some of the sub-stations are far apart. It takes time and effort to manage, with low accuracy and low degree of automation. , Mastering the amount of water resources and monitoring water flow have brought great difficulties

[0004] For the detection of water resources, the traditional flow measurement methods are mainly manual methods such as current meter method, buoy method, gradient method, etc., but these technologies cannot realize online real-time measurement and transmission.
