Introduction At present, China's water supply system large systems throughout a wide range, number of dispersion. Bring to the management and monitoring greatly inconvenience. Jinan Tenda developed based on this case, GPRS pipe network wireless pressure monitoring system. Pressure Monitoring System wired pipe network in the past, compared to the advantage of the entire monitoring network without wiring, reduce system construction costs and shorten the time of system construction. Take advantage of the computer RMON pipe network pressure and the flow can sit in an office administrator, improve management efficiency, to ensure the safety of the entire pipe network to work properly. System the composition pipe network pressure monitoring system by the pressure and flow data collection terminal, GPRS data transmission terminals, monitoring software, computer, GPRS network. Each monitoring point in the course of their work, to install a pressure data collection terminal, pressure pipe network acquisition. Each data collection terminal through the RS232 serial port connected to the GPRS data transmission terminal. Data collection terminal to the transmission terminal, GPRS wireless network, the data is uploaded to the monitoring computer. The the administrator operation monitoring software can query historical data, real-time data. System function RS232 industry standard data interfaces: the GPRS digital transmission terminal for the industrial-grade standard design is capable of receiving 0 ~ 5V, 4 ~ 20mA signal. Users can configure their own various sensors, pressure acquisition collecting water level, level collection. Pressure, level, flow and real-time monitoring and surveillance. Data transfer SMS and GPRS real-time transmission of two ways. Has switching and analog input interface. Support the switch, analog wireless transmission. Built-in timing circuit, the remote setting data upload time, timer switch function. Wireless remote control field devices of computers, cell phones are two ways to start and stop. GPRS data transmission terminal built-in relay wireless remote control electrical switches, limit alarm: preset the monitoring limit to GPRS data transmission terminal through software, when the water level value, voltage value, the current value of the overrun, GPRS digital transmission terminal will alarm information is uploaded to the host computer monitoring software. The administrator can also set the phone to receive alarm short interest. Can use the phone queries each point pressure value. Summary Jinan the Tengda electronic pipe network pressure monitoring system uses GPRS technology, so users can keep abreast of the pipe network pressure information; GPRS Internet traffic accounting, is one of the most economical means of transmission; entire data transfer dependent on mobile network remote transmission can be realized in the country, between the detection point and the office without wiring, greatly reduce the cost of the RMON engineering construction.
