Problems solved by technology

[0005] Traditional gas pipeline network management methods are difficult to achieve real-time data collection and transmission of remote nodes in the pipeline network. The ideal data transmission method is based on wireless communication transmission. In addition, the distribution of the pipeline network is wide and the layout is intricate. Therefore, it is necessary to The automatic monitoring system of the Internet is based on the spatial geographic model

Embodiment Construction

[0036] The hardware device of the present invention is mainly composed of two parts: a measuring point station and a monitoring center server. The measuring point station includes a data acquisition module and a GPRS module. The data acquisition module is responsible for the collection of pipeline gas flow, pressure and temperature signals; the GPRS module transmits the measurement information of each measuring point station in time through the mobile GPRS wireless data transmission network; the monitoring center server receives in real time The data from the GPRS network is authenticated and sent to the server host of the monitoring center, and the data is restored and displayed through the system software, and the data is processed.

[0037] The functional modules of the system can be divided into four parts:

[0038] (1) Data acquisition module: the acquisition function of pipeline gas flow, pressure and temperature signals is completed by the measuring point station;

Abstract

This invention relates to an automatic monitor method and a system of city gas ductworks, which sets up test stations at the nodes of the ductwork to collect gas flow signals in pipes of the nodes, sets a monitor center server transmitting data information collected by the test stations to the test stations via radio communication network and storing space geographical data of the parts of the ductwork and installing and operating data process and leakage monitor software based on the GIS technology to pre-warn leakage of ductwork and transmitting the leakage information to maintenance stations.

Description

technical field [0001] The invention belongs to the field of pipeline network operation monitoring and wireless data transmission, and in particular relates to an automatic monitoring system of an urban gas pipeline network and a monitoring method adopted by the monitoring system. Background technique [0002] At present, the monitoring technology of most gas supply units in my country is still very backward, especially for the management of the transmission and distribution pipeline network, it is basically still to use special personnel for regular fixed-point inspection and transcription, which not only has a large workload and low efficiency, but also has a high error rate and Human error is high, and it is difficult to realize real-time data collection of monitoring points. Adopting the traditional transmission and distribution pipeline network management method, firstly, the operation cost is high, and secondly, it is difficult to adapt to the requirements of modern man...
