Problems solved by technology
[0003] In the traditional water resource dispatching, it is usually a backward mode of manual control, with clumsy on-site operation, slow information transmission, slow response, time-consuming and labor-intensive, high investment and low effect
In addition, it is necessary to change the control mode of the existing PLC water resources dispatching system in some irrigation areas to solve the bottleneck problem of high cost, strict power supply requirements, and difficulty in adapting to the harsh natural environment in Northwest China.
In view of the current situation in the north, especially in the northwestern region, where there is drought and little rain, large annual evaporation, large crop planting area, concentrated irrigation time, large irrigation canal system (main canal, branch canal, bucket canal, etc.), and scattered and remote monitoring and control stations, it is necessary to solve the large amount of canal system. Difficulties such as wide area, long communication distance and difficulty in maintenance, as well as the high cost of using traditional water resource management methods, low resource utilization efficiency, randomness, and serious waste, etc.

The invention discloses a water-saving agricultural ecological information acquisition system. The equipment can realize acquisition, storage, processing and reporting of ecological information in an irrigated area. The equipment mainly has the functions of acquisition of information on water levels, rainfall, evaporation capacity, temperatures, wind power, geographical coordinates and soil moisture content, intelligent proportion integration differentiation (PID) control on gates and gate level image information acquisition and transmission. The equipment is powered by solar energy, and the comprehensive management is performed on a power supply, so that the electric energy is efficiently utilized. The equipment has three communication modes, namely general packet radio service (GPRS), the 3rd generation (3G) and optical fibers, and can be well compatible with a local communication network.
Description
technical field [0001] The invention relates to collection and control equipment, in particular to water-saving automatic management and control equipment for agricultural irrigation areas. Background technique [0002] my country is a large agricultural country, but also a country that is extremely short of water resources. The per capita water resources are only 1 / 4 of the world average, and the water resources per unit area of cultivated land are only 3 / 4 of the world average. The waste of irrigation water is very serious, and the utilization rate is only about 40%. In particular, the western region is dry and rainless, and water resources have become a bottleneck restricting the development of the western region. In order to develop modern agriculture in such a dry area, limited water resources must be saved and rationally used. The popularization of high-tech water-saving irrigation technology in my country is low, the utilization rate of irrigation water is extreme...
