Introduction of the application case of EVOC IPC in the intelligent system of reservoir information: China's water conservancy industry has a long history, and the management and development of the water conservancy industry is the most difficult problem in information management, such as flood and drought information, water quantity and quality information , water situation information and water engineering information, etc. are the data reports that the water conservancy department shall provide to the state and related industries on schedule every year. In this article, Qingdao Henryda Computer Co., Ltd., as a well-known supplier of embedded computers in China, will introduce the application of EVOC IPC in this regard for friends:
System composition
The information system of the reservoir is mainly composed of the dam safety automatic monitoring system, the water condition telemetry system, the office automation system, the reservoir optimization and adjustment system, the gate monitoring system, the image monitoring system, etc., and the various subsystems are integrated through the computer web system , to achieve data sharing and collaboration between systems to provide a field of information visit. Complete the sharing of system resources based on LAN (such as printers, hard disk resources, document sharing, etc.). Using the database management technology intensive processing information to link the Web technology application, develop a Web summary information publishing system based on the B\S method, which can easily and intuitively allow users to obtain the information of each system. By connecting to the Internet by means of Fibre Channel, wireless access, DDN dedicated line, etc., you can inquire about professional information such as image information and satellite cloud images in real time, and use the Web method to provide information inquiries to the supervisory department. At the same time, you can also complete mobile office.
1. Automatic monitoring system for dam safety
This system is a distributed web page layout. It is mainly composed of a front-end computer (using EVOC IPC), a central controller (CCU), an on-site measurement control unit (MCU), sensors and communication pages. The MCU is arranged in the observation room, combined with the sensor, and the EVOC industrial computer, as the middle node of the web, is combined with each MCU by the RS485 bus to complete the operation control of the sub-system and the integration with the upper-level web system.
The measurement and control unit in the system can automatically collect data from the sensor according to the pre-built time period, and send the collected data to the EVOC IPC and store it in the MCU's memory; it can also implement the data sent by the EVOC IPC. Random collection of commands, data collection for any sensor. The system operator can check the current or historical data at the adjustment center station, and use tools such as graphics, reports or analysis software to further analyze the behavior of the dam.
2. Water condition telemetry system:
The system construction includes front-end computer (EVOC industrial computer), telemetry intermediate terminal, transceiver station, communication power supply, omnidirectional antenna and coaxial arrester, etc. The intermediate station absorbs various water parameters collected in real time from each telemetry station. The front-end computer of the intermediate station will identify and correct the data lines extracted, classify and rectify them, causing the data files to be stored in the memory of the front-end computer. The resulting data files can be stored in the server database via the local area network. The communication method can use communication cables, radio stations, satellites, wireless short messages and other methods for communication to ensure channel circulation.
3. Gate monitoring system
The main content of the system is to automatically collect and transmit the water level of the sluice gate, the working conditions of the sluice gate, and the image information through the computer monitoring system, so that the gate opening and closing and automatic gate control can be remotely controlled during the monitoring; operating conditions and surrounding conditions. The system equipment is mainly divided into two parts: the control building monitoring center and the gate on-site monitoring device. The monitoring center is composed of the system front-end computer and the computer web field and application software. The installation of the component PLC and the equipment of the information transmission channel. The on-site PLC is used to control the gate opening and closing structure, the gate opening degree is used to determine the gate opening in real time, and the hydrology and water conservancy calculation is carried out. Based on the measured hydrological data, the gate opening is automatically set to improve the automatic control level and reduce manual deviation. Through the establishment of guard equipment, real-time measures can be taken for unforeseen situations that occur during the implementation process. Connect the remote image monitoring system to realize automatic control of unattended gates.
4. Reservoir optimization and adjustment system
The main content of optimizing the adjustment is to make a flood adjustment decision based on the flood discharge capacity of the downstream rivers to provide optimal storage capacity for irrigation water under the premise of ensuring the safety of flood control of the reservoir when the flood falls. The hydrological materials supplied by the computer hydrological telemetry system and the dam body's seepage pressure active monitoring system are used as the decision-making basis for the flood control of the dam body.
5. Image monitoring system
The CCTV surveillance system is an adopted electronic technology method, which carries out sensor imaging, signal transmission, intensive surveillance, image recording and linkage control of the remote scene. The computer digital monitoring system is a new product in the monitoring and alarming industry. It adopts the mode of digital video recording and recording, adopts the high-performance EVOC industrial computer, increases the number of video recorder image input channels, and improves the performance speed of multi-screen images. The functions such as the control of the PTZ and the lens, together with the excellent human-computer interaction interface, constitute a digital supervision and alarm system focusing on the computer.
6. Office automation system
According to the functions of each office of the reservoir, assign their respective authority, and conduct the question of sharing data in the reservoir informatization information system. And through the LAN page to share system peripheral resources, such as printers, scanners, digitizers, etc., to complete file sharing services, FTP file transfer services, Email e-mail services, web page information announcement, LAN communication services, etc., you can click The process of informatization equipment has completed step by step financial computerization, personnel and labor management, material management, public document circulation, financial computerization, etc.
