Abstract

The invention discloses a remote monitoring terminal for urban pipe network pressure. The remote monitoring terminal comprises a pressure transmitter, an AD (analog / digital) converter, a central processing unit, a GSM module and a GSM antenna. The central processing unit is provided with an RS232 interface. The pressure transmitter is connected with the input end of the AD converter. The output end of the AD converter is connected to the RS232 interface. The input end of the GSM module is connected with the central processing unit. The GSM antenna is connected with the output end of the GSM module. The remote monitoring terminal for urban pipe network pressure has the advantages that pipe network pressure signals output by the pressure transmitter can be wirelessly propagated by the GSM network and layout of large urban pipe network pressure monitoring terminals can be simplified.

Description

technical field [0001] The invention relates to the field of urban pipe network pressure monitoring, in particular to a remote monitoring terminal for urban pipe network pressure. Background technique [0002] The urban water supply and gas supply dispatching monitoring system can monitor and control the operating equipment on the remote site, so as to realize the transmission of pipeline pressure data and facilitate the automatic control of the valve switch, which can reduce the failure rate of the urban water supply and gas supply pipeline network and improve the reliability of the system. Response time to network faults. The data acquisition terminal of each water source monitoring point uses a pressure sensor, and after the sensor signal is processed by the pressure transmitter, the pressure information is transmitted to the dispatching monitoring center by a dedicated line. [0003] Automatically collect real-time data of pipe network pressure, and the monitoring cente...
