Irrigation district big data collection management system and method based on water affair Internet of Things

Abstract

The invention discloses an irrigation district big data collection management system and method based on water affair Internet of Things. The system comprises a server side, a switch, a first wirelesssignal transmission module, a second wireless signal transmission module, an LORA concentrator, an RTU collection module and a detection module, the first wireless signal transmission module, the second wireless signal transmission module and the LORA concentrator are connected with the switch, and the switch is connected with the server side; the LORA concentrator is interactively connected withthe first LORA transmission module, and the LORA concentrator is interactively connected with the second LORA transmission module; the method is applied to places covered by operator networks. Any one of GPRS, 3G, 4G and 5G functions is used for network transmission; for a place without operator network coverage, transmission is carried out through an LORA concentrator and a GPRS / 3G / 4G transmission mode, and the problems that GPRS / 3G / 4G signals of a remote irrigation area are not covered, and the water level, flow and rainfall cannot be transmitted are solved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy informatization, and in particular relates to a system and method for collecting and managing large data in irrigation districts based on the Internet of Things for water affairs. Background technique [0002] At present, the information management of irrigation areas in my country is still at a relatively low level. Usually, PLC is used to control the sluice / valve / pumping station, and RTU is used to collect data such as water level and flow, and the data is transmitted through GPRS / 3G / 4G, self-built optical cable, and leased optical fiber line, and is configured in the dispatching center. Two sets of systems, a control system based on C / S architecture to control the opening and closing of gate valves, and a management system based on B / S architecture to manage water measurement, water fee collection, water volume scheduling and other services in the irrigation area.

AI Technical Summary

Problems solved by technology

[0004] 1. For information transmission, in some remote irrigation areas, where the operator's network is not covered, the construction cost of self-built optical cables is high, and at the same time, there is a lack of professional operation and maintenance personnel, making maintenance difficult

[0005] 2. Two sets of systems are used for control and management, which is inconvenient to use

[0006] 3. Informatization of traditional irrigation areas, using PLC to control the gate valves, and RTU to collect flow, image and other information, the construction cost is high

[0007] 4. In traditional irrigation areas, models are usually used for water demand prediction and water allocation. Due to the many parameters involved, parameter adjustment is troublesome and the error is large
