Design And Implementation Of The Rural Drainage Station Hydrological Measurement And Control System

Water conservancy is the important infrastructure of national economy, is an important material foundation to realize the sustainable development of social economy。With the continuous development of the information technology and application in the field of the Internet of Things, water conservancy informatization is gradually emerging, become one of the important measures of water conservancy modernization. South in our country, full of a large number of small and medium-sized rural water drainage station, assuming the task of farmland irrigation and drainage, is closely related with the development of agriculture in our country, so the design of a set of suitable for small and medium-sized rural drainage station hydrological measurement and control system is of great significance.This topic is based on a Rural drainage station renovation project,combined with a variety of communications technology to design a set of hydrological measurement and control system. Rural drainage station hydrological measurement and control system design and implementation. Rural drainage station hydrological measurement and control system design and implementation of the consists of two parts, upper machine part and lower machine part. The upper machine part adopts B/S structure of Java Web server, realize the drainage station running information stored query and display, and other functions. The lower machine part mainly to complete the reservoir water level and temperature of waterlogging drainage station information acquisition and transmission function such as voltage and current. The lower machine part is mainly composed of central control module, wireless temperature measurement module, wireless receiving module, water level meter module and multi-functional electric meter module.The central control module of a series of STM32F103microprocessor as the core, periphery expands the GPRS function RS485bus interface and analog acquisition function. The central control module through the RS485bus interface connection433M wireless receiving module and multi-function meter module, read the temperature of the voltage and current information unit. The wireless temperature measurement module adopts the temperature of the contact temperature sensor acquisition unit, temperature in wireless communication way information is sent to the wireless receiving module.The central control module through the analog acquisition interface connection level meter module, water level information In addition, the central control module will read all of the information through the GPRS communication mode to first place machineAfter the actual installation and debugging, at present the system runs stably, can satisfy the design requirements of the project.
