5 SCADA pumping station based on Saiyuan safety communication system
5.1 Saiyuan Remote Security Communication System
Saiyuan Industrial Remote Security Communication is a completely independent communication system. It is different from the low-speed connection system such as MODEM dialing and GPRS on the market. It is different from the way that the computer needs remote desktop in the field. The following salient features:
(1) Engineer's real-time minute-level response, real-time operational guarantee.
(2) Global internet coverage support, supporting ADSL, VDSL, 3G and other methods.
(3) Support various industrial Ethernet protocols such as Profinet, Ethercat, Ethernet/IP, MODBUSTCP.
(4) Live video is transmitted along with industrial data.
(5) PLC program level control, data OPC acquisition.
(6) Data real-time bidirectional transmission.
(7) Erection and configuration are simple and efficient.
(8) The latest Saiyuan patent security communication technology, data security and stability.
(9) Both ends do not need fixed IP, and the data is directly connected to the point-to-point without going through a third-party server.
(10) One-time investment, no follow-up product service fees.
(11) Support data dual channel hardware and software redundancy.
(12) Data security encryption up to 1536-bit S-Link encryption.
(13) Communication security authentication mode: support fingerprint authentication, SMS authentication, USBKEY authentication, U-KEY authentication; CA authentication, national secret authentication system, dynamic token authentication, X.509 digital certificate authentication.
(14) Password protection measures: use password strength detection, periodic password change request, anti-brute force cracking strategy, account lock unlock function, administrator password permission setting, soft keyboard, graphic verification code and other input verification methods.
Supports remote viewing and modification of devices such as Pad, smartphone, notebook, netbook, etc.
5.2 Race far operation support center function
(1) Data monitoring function: Each pumping station can start and stop state, protection status, current, voltage, etc., and all information that can be concentrated in the programmable controller can be monitored.
(2) Remote control function: control the start and stop work of each drainage pump and grille in each pumping station, remotely switch the control mode of each drainage pump of each pumping station, etc., all the equipment connected to the peripheral of the programmable controller Remote start and stop control.
(3) Alarm function: In the server, regularly store various monitoring data, event alarm information, real-time monitoring data and other data communication back to the operation center, then you can establish various parameters early warning guarantee mechanism, such as warning the sewage tank liquid level Water level alarm, harmful gas exceeding the standard alarm, etc. At the same time, it supports various types of information query, and can generate reports on monitoring data and alarm data, and the data can be exported to support print output.
(4) Video surveillance: The video is transmitted to the information center through the on-site industrial Ethernet to realize real-time monitoring, video data storage and playback. The camera field can be remotely controlled and more humanized.
Monitoring interface: Real-time monitoring data and video are displayed on the same interface. It can monitor multiple pump station videos and data on the same screen, and can also switch to video and data display of a single pump station.
(5) Rights management: Different usage rights are granted to different operation users.
(6) Open: The number of pump stations monitored can be increased or decreased arbitrarily. Reserve communication interfaces with other systems.
6 Conclusion
Based on PLC, host computer, frequency converter and other equipment, the drainage pump station control and transmission industrial network system satisfies the overall monitoring and intelligent needs of the drainage pump station. Saiyuan's industrial remote system with the latest patented industrial safety communication technology realizes the remote collection and centralized monitoring function of the drainage pumping station, which greatly reduces the cost of regulation, maintenance and early warning, and establishes the whole life of the drainage pumping station through the system. The cycle management system, in the 21st century, has transformed from an isolated island of drainage pumping stations into information networking and centralized control. It is a huge transformation brought about by informationization, intelligence, network and cloud computing. The matching of urban drainage pumping stations has achieved good results at home and abroad.
