Problems solved by technology
[0004] If the city gas pipeline cannot be cut off and emptied in time in the event of an earthquake, fire and other disasters, as well as pipeline leakage, the traditional on-site manual closing by rescuers will far fail to meet the requirements of emergency rescue, and the consequences of the disaster will be expanded.

The invention discloses an automatic cutting-off and emptying system and method for a building gas vertical pipe based on wireless transmission. The system comprises a plurality of wireless gas sensor modules which have an information transceiving function and are used as wireless communication network nodes, a plurality of wireless emptying valve modules which have an information transceiving function and are used as wireless communication network nodes, a plurality of wireless pipeline cutting-off valve modules which have an information transceiving function and are used as wireless communication network nodes, a plurality of wireless switch modules which have an information transceiving function and are used as wireless communication network nodes, wireless routers and a wireless building central controller. The system and method disclosed by the invention can test gas concentration in real time, and under a disastrous condition, one-off control over a gas valve switch is remotely and quickly performed, so that disaster consequences are prevented from being expanded.
Description
technical field [0001] An automatic cut-off and venting control system for urban building gas pipelines based on wireless sensing is most suitable for rapid control of building gas pipeline valves and pipeline venting in the event of disasters such as fires and earthquakes and pipeline leakage. Background technique [0002] With the development of computer technology, control technology and communication technology, the building automation industry has achieved great development in the past ten years, and the building control products following the standardized communication protocols of BACnet, LonTalk and EIB occupy a dominant position in the industry. The communication transmission medium (such as twisted pair, coaxial cable and fiber optic cable) adopted by the building automation network using these communication protocols is usually wired. Compared with building control products using wired network communication technology, the most attractive aspects of wireless solut...
