Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, the present invention is a wireless sensor network node device for natural gas pipeline network safety monitoring. The node device is mainly composed of four parts: a power supply module 1, a sensor module 5, a processor module 11 and a wireless communication module 18. The inventive node device is installed on the outer wall of the pipeline to be monitored, and the sensor module 5 collects environmental information parameters around the pipeline, and transmits all parameters to the processor module 11 for processing and storage, and finally sends them to the wireless communication module 18, and the wireless communication module 18 Then the parameter information is sent wirelessly to the adjacent sink nodes according to the fixed communication format. The power module 1 is used to provide power for the entire node device. ...

Abstract

The invention relates to a sensor network node device of security monitoring of a natural gas pipe network, mainly comprising a power module, a sensor module, a processor module and a wireless communication module. The node acquires parameters related to the security of pipelines and ambient by an acceleration sensor, a gas sensor and a temperature sensor in the sensor module under the control of the processor module; the nodes carry out data interaction by the wireless communication module, construct self-organization and multi-hop wireless sensor network, and finally transmit the information related to the safety at the nodes to a monitoring center. The wireless sensor network technology is adopted to carry out on-line real-time monitoring to the natural gas pipe networks of cities, and can find insecure factors of damage, leakage and the like of the construction in time, improve the security of operation of the natural gas pipe networks and reduce manual maintenance cost.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless sensor network node device for safety monitoring of a natural gas pipeline network. Background technique [0002] The natural gas supply system is one of the "lifelines" of the city, and its main transmission and distribution method is pipeline transmission. As the pipeline network becomes more and more complex and the pipelines become longer and longer, major safety hazards become more prominent, and pipeline leakage and resulting explosion accidents occur from time to time. Therefore, timely identification of safety hazards such as pipe network leakage is of great significance to ensure urban safety. [0003] At present, for the safety of the natural gas pipeline network, the manual inspection method is mainly adopted, that is, the maintenance personnel of the pipeline network arrive at the site and use various testing instruments and combined with experience t...
