Hydro Turbine Pumping Station In Jiangxi-Wireless Transmission Radar Level Sensor
Hebei Huachuang M&C Technology Co.,Ltd is located in the Economic Development Zone of Fengnan District, Tangshan City. It is a high-tech enterprise specializing in the research and development and production of microwave material level measurement and control equipment. The company was established in 2014 and relies on domestic universities and colleges. The cooperation platform is dedicated to the research and development of radar level measurement and control technology, and develops a centralized control and detection system based on customer needs. Our company strictly controls the quality of components and raw materials, and produces each product with the spirit of artisans. Continuously provide customers with satisfactory high-precision, high-quality, safe and reliable measurement and control equipment.
2. Project background
Turbine pump station in Jiangxi Province is located in the Xinjiang River Basin, one of the five major rivers in the Poyang Lake system. Mainly provide main business: pump water irrigation, power generation concurrently.
In order to give full play to the role of river basins and reservoirs in flood control and drought relief and water resources scheduling, and to ensure the safety of the operationof river basins and reservoir dams, according to the characteristics of a water turbine pump station in Jiangxi Province, according to the characteristics of farmland irrigation, flood disasters and flood control status To learn from years of experience and study relevant requirements. After research and discussion, the marketing and technical team of Hebei Huachuang Measurement and Control Technology Co., Ltd. put forward the application of modern technologies such as computer, communication, and telemetry, and successfully solved the real-time detection and wireless transmission of the upstream and downstream water levels of a turbine pump station in Jiangxi Province.
3. Construction content
The water level detection system of a turbine pump station in Jiangxi Province is divided into hardware platform and software platform.
The main construction contents of the hardware platform are: network system, information receiving and sending equipment DTU, HCIOT-71 radar monitoring device and power supply system.
The software platform is mainly the Internet of things system platform and background server software basic platform of Hebei Huachuang Measurement Control Technology Co., Ltd.
1. Design principles
1.1. Persist in putting people first and ensure the safety of the people's lives as the primary goal.
1.2. Adhere to the principles of reliability and standardization. Reliability refers to the design that emphasizes the selection of equipment and technologies with stable and reliable performance, anti-interference and anti-harsh environment capabilities to ensure that the system can work stably and reliably for a long time. This is the prerequisite for the system to be effectively applied.
1.3. Adhere to the principle of combining advancedness and practicality. Not only should we use advanced technology as much as possible to achieve the goals of high efficiency, speed, and reliability, but also choose equipment and technologies that are easy to install, operate, and maintain, and have high effective usability according to the actual situation, to achieve a combination of advanced and practical aims.
1.4. Adhere to the principles of scalability and openness. Information technology is a very fast update and upgrade technology in contemporary high-tech, and information application is often a process of continuous construction and improvement. Therefore, the principle of scalability and openness needs to be taken into account to provide once again for the built system. The need to upgrade and increase applications.
2. Functional requirements
The technological requirement of this system is to use DTU terminal equipment to collect data, supporting low-power radar water level Sensor, and transmit the collected data to an independent cloud platform server developed by our company through GPRS or 4G signals. Users can use web clients and mobile phones. View the real-time data and historical data on the public account, and realize remote setting and control. High-performance server, advanced IOT system, powerful database software and precise radar water level sensor can provide customers with stable and reliable services.
2.1 System login
This function completes the user login, and different identities will have inability to function. The login process verifies the user name and password. This project has set up five login users, including the pump station director, office director, maintenance director, statistician, and backup user. In addition, the system has hierarchically set the functions of station master and director with password modification and user logout.
2.2 Web client display
Users can view real-time data, historical data and curves through the web client, our company's Internet of Things platform, and can export historical data in the format of Office2003 version. The display page is shown below:
2.3 Mobile display
By following the WeChat public account of Hebei Huachuang Measurement Control Technology Co., Ltd., you can enter the mobile phone to view real-time data and historical data and curves through the same username and password as the WEB client. As shown below WEB client. As shown below:
3. System practicability and reliability
The system meets the characteristics of flood control management and business requirements. The interface is friendly and concise, the operation is simple and convenient, and the information display is intuitive, which makes the system very practical. The system function module has stability, and it will not crash in any situation, and it will not crash. It ensures that each system can withstand long-term operationtests, and ensures the correctness and integrity of information collection, transmission, storage and query .
4. Installation of radar and hardware
The process requirements to be met by the project are to monitor the water level of the Xinjiang River channel, to monitor it through on-site power supply (not powered by solar energy), and transmit the liquid level signal to a wireless transmission system such as DTU via RS485, and collect it through GPRS or 4G The data is transferred to an ind pendent cloud platform server on the computer.
The HCIOT-71 non-contact wireless transmission radar level meter selected for thisproject adopts thread or flange installation. During installation, pay attention to whether there are obstacles or stirring devices on the site. Do not have large vibration motors or variable frequency and soft Start the equipment such as Qi, and install itas vertically as possible during installation; pay attention to the wiring order to prevent burning out DTU, radar and other instrumentation equipment.
Through the vigorous cooperation of the personnel of the pumping station, the project was successfully completed. The pictures on the scene are as follows:
