In urban wastewater treatment, urban sewage treatment facilities have been referred to the prominent position of urban infrastructure construction, urban sewage treatment facilities construction has entered a new stage of development. But all over the country for water quality monitoring pollution and sewage canals still remain in the manual monitoring phase, difficult to reflect the situation of enterprises and urban sewage discharge continuously changing. In terms of water pollution continue to strengthen governance, but because of weak driven by environmental awareness and interest, and many other factors, free and non-standard sewage waste-water treatment of sewage, causing serious environmental pollution occurs when there is a case, thus providing a monitoring regulation effective, practical and advanced monitoring systems and solutions, build sewage-line monitoring system is extremely urgent to improve the water quality monitoring capacity is imperative.
In monitoring sewage treatment projects, involving sewage treatment monitoring system, a lot of the necessary equipment or unattended monitoring point by topography, climate, and other factors affect the scope of monitoring, not suitable for wired and wireless data radio and other data transmission but they also have poor mobility, high costs, poor scalability, maintenance inconvenient shortcomings, while the mobile 4G network coverage, high-speed data transmission and always-on features, with flexible tariff ways to make 4G communications in sewage processing monitoring system with unmatched cost advantage
The sewage system is a monitoring system for monitoring the effluent discharge point, central station monitoring and management center thereof. The system can realize the enterprise wastewater and urban sewage automatic sampling, on-line monitoring and line monitoring of major pollutants flow; real-time grasp of the total enterprises and urban sewage discharge and pollutant emissions and monitoring data automatic transmission; the monitoring points water quality parameter automatic gathering, processing, storage and telecommunications transmission, computer control center of the central station measured data summary, collation and comprehensive analysis; monitoring information is transmitted to the EPA, the Environmental Protection Agency for supervision and management of enterprises. The system is as follows:
Sewage discharge monitoring points
Sewage treatment monitoring points using a variety of sensors or special instruments, collection and sewage treatment-related physical and chemical parameters. Such as sewage treatment equipment operating conditions, industrial water and sewage flow, sewage PH value, the relative turbidity wastewater. Various data transmitted from the communication port to monitor Caimore 4G DTU, the data from the Caimore 4G DTU labeled TCP / IP packets, sent to Caimore 4G DTU Control Center station set in the data center has a fixed IP address or domain name server port.
Central station monitoring system consists of a computer data communications subsystem, a data processing subsystem and reporting system, the main function of the completion data communications, data processing, reporting, statistical analysis.
Data processing subsystem, reporting system as the main man-machine interface, close monitoring point transmission of information to other sources of information and monitoring; responsible for monitoring information classification, screening and comprehensive analysis; completion of the data statistics, computing, processing, It can automatically generate various reports; with storage, display, record, print, statistics and other functions, but also can send inquiry about the command and control information to the monitoring point.
Caimore 4G DTU on each monitoring point is automatically appropriated 4G network is powered on, and pre-set IP address or domain name to establish a TCP link between such a monitoring center and various monitoring points to achieve a two-way transmission of data
1.Cellular: 4G network for high speed data transmission.
2.Com port: Serial port,RS232 or RS485
3.Protocol: TCP/IP,UDP ect transparent protocol to send data
4.Wireless connection mode:1.APN 2.Public fixed IP 3.DDNS(public dynamic IP+DNS link) which flexible to choose any networking.
5.Real time communication between server and client
6.ARM Chipset and industrial grade components to endure high performance and stability.
The advantage of 4G solution as below:
1.Big market in Machine to Machine(M2M) communications, for SCADA and telemetry
2.Advantage of low cost and an existing backhaul network to get the data to the control centre
3.No control on the coverage, or availability of the service at geographically remote monitor and control points
4.For power utilities, will network continue to operate when there is an widespread power failure?
Caimore Communication devotes herself to IOT and the industrial automation fields , provides wireless products, Xiamen focus on supporting high-tech enterprises; 12 years of industry research and development and industrial applications accumulation test.
