subject: The Use Of Industrial Computers For Monitoring Water Distribution Networks [print this page] Monitoring system of water supply systems - systems with a specific structure.Part of the devices in the system are spaced far enough apart, but the control equipment is concentrated in a particular place. In this case, selection of appropriate monitoring system is a nontrivial task that requires the use of semiconductor and wireless technologies. Solving this problem we offer a monitoring system of water supply systems, industrial computer uses a 9201 NPE-GPRS. The system allows for flexible, easily adapts to the needs of the client, monitoring and control system, based on the use of network (Internet) and wireless (Network GSM) technology.
The monitoring system consists of two parts: the monitoring and control stations and remote control stations. The latter are in places where you need to be monitored. This set of sensors form the data reflecting the controlled parameters such as pressure, temperature, flow rate, etc. Can be controlled by any of the parameters depending on the needs and the specific implementation of the telemetry system. This data is transmitted to a computer NPE, which provides processing and analysis. In the event of failure or lack of communication with the sensors, the module can be sent immediately via the Internet (e-mail) or network GSM (SMS) messages specified in the settings for subscribers.
The data coming to the NPE, and the results of the analysis are sent via Ethernet or wireless GSM network to a central computer. Method of transmission of information depends on the presence of conductive channels of communication and the desire of the user of the system. In the event of an accident can be an immediate change in the communication channel, or duplication of data transmission for both of them. The central computer analyzes the data coming from all positions of control. In addition, the system provides remote diagnostics functionality of all devices included in the telemetry system. It is also possible its extension and modification.
An important element of the system is the monitoring and control station, where the controlling computer with installed software such as SCADA. The computer analyzes the data and provides graphical ones. The equipment also includes a modem FASTRACK 20, which is used to exchange data via the GSM. At control posts should also be a GSM modem with the control module. The latter is integrated into the NPE and does not require any additional devices.
The task of industrial computer NPE is to gather information about the parameters of the controlled sensors and recording. In the case of filling the memory built into the module, all information is transmitted via modem to a monitoring station, and management. Upon completion modus rtu of a successful communication session is filled with memories back information about the controlled parameters. This method of communication makes it possible to reduce the cost of data transmission. In an emergency, or the command station monitoring and control, removal of data can be carried out also by the partial filling of the memory.
Any modem, as well as the Internet m-bus is allocated a specific address IP. This allows you to send data between any devices that are part of the system. IP numbers are assigned for a long time, or change in the registration unit in the data network.Each transmitted data packet contains information about the IP of the sending and receiving devices, which scada allows you to organize data and to track the sources of information.
