WRMS water resources monitoring and dispatching management system

wrms water resources monitoring and dispatching management system is based on routine monitoring, through various fast and effective means, to timely and accurately grasp the changes of water quality and quantity, and according to the water demand of irrigation areas, gate opening and closing information, reasonably control the gate, realize the joint dispatching of water resources, and achieve the purpose of rational allocation of water resources and disaster prevention and reduction; At the same time, it will alert the water quality changes and sudden pollution, and provide scientific basis for relevant departments to take emergency measures to prevent pollution

system composition

wrm's ability to deal with trade protectionism is enhanced. S water resources monitoring and dispatching management system is composed of automatic water monitoring subsystem, automatic soil moisture monitoring subsystem, automatic water quality monitoring subsystem, gate monitoring subsystem and video monitoring subsystem. The system framework is shown in Figure 1. Each subsystem can form an independent system, and can be seamlessly embedded into Nari water wds9002 water dispatching platform through a series of plug-ins developed, Realize the unification of interface and data flow. It has strong flexibility and reliability

water regime telemetry system

the water regime telemetry system mainly completes the real-time automatic collection, reception, processing and storage of the amount of cracks and water level data

soil moisture monitoring system

farmland soil moisture is an important basis for the rational scheduling and distribution of irrigation canal water. The soil moisture monitoring system monitors the soil moisture per unit volume (volume) in real time, as shown in Figure 2

automatic water quality monitoring system

the main water quality parameters monitored by the system include five water quality parameters (temperature, pH, dissolved oxygen, conductivity, turbidity), ammonia nitrogen, permanganate index, total phosphorus, total nitrogen, phenol, etc. see Figure 3 for typical water quality system composition

the automatic water quality monitoring system has the following basic functions:

automatic monitoring. Automatically realize the collection and analysis of water samples and the processing, transmission, storage and other functions of data

continuous monitoring

measure and automatically calibrate the standard solution before detecting water samples

regular automatic cleaning, automatic correction, automatic filtration and other functions

the flexible and reliable water intake method meets the requirements of long-term stable operation on site, and you can simply change some states

it has the function of information extraction and scanning, and automatically stores the extracted and collected data into the database in a unified format

automatic data transmission function. Support PSTN and gsm/gprs/cdma, and can expand ultrashort wave and satellite channels

visual display. It can display the operation status, monitoring data and analysis results of the instrument in real time

automatic alarm

it has two control modes: local control and remote control

remote call test function

powerful report function. Carry out rationality inspection and real-time processing on the monitoring data, and store it in the database according to the specified format

equipment operation status management

the automatic water quality monitoring system has good openness and expansibility, and can seamlessly access various types of water quality sensors or analytical instruments according to user requirements

gate monitoring system

the gate monitoring system uses the programmable controller as the control station, takes the fieldbus and industrial status as the communication network, uses the photoelectric encoder to measure the travel, and adopts the soft start and contactless control technology to realize the distributed control system of local control, centralized control and remote control of the radial gate, flat gate and fast gate

the gate monitoring system has the following technical characteristics:

the hardware is equipped with multi-level protection equipment, and the system reliability is high

local control takes priority, remote control assists

automatically collect the gate opening and equipment operation status, and send information to the central control console

perfect user authentication system and detailed operation records during remote control, so as to ensure the safety of the system

have the gate operation stuck fault Stall fault protection function

supports PSTN, GPRS, CDMA, tcp/ip and other channels

has the gate sliding and lifting function, and the sliding point parameters are optional

with motor overcurrent, overload, phase failure, undervoltage, short circuit, locked rotor protection and other functions

with gate limit travel protection function

with fault alarm function, there will be more experimental requirements

provide gate operation and opening report

video monitoring system

the video monitoring system adopts the latest embedded web video monitoring technology, and the video coding format can choose MJPEG, MPEG2, and MPEG4 coding methods according to user needs and network bandwidth. The video software adopts B-S architecture. The client does not need to install software, and can browse images through the browser. This system has the following characteristics:

wide control area

can form a very complex monitoring network

strong system expansion ability

stable and reliable performance

perfect image recording, retrieval and playback functions

perfect hierarchical authority control
