The invention discloses an alarm system for the indoor gas leakage, and comprises a gas detection terminal, a signal processing unit, a gas evacuation unit, and a monitoring unit. The gas detection terminal is in communication connection with the signal processing unit; and the signal processing unit is in communication connection with the gas evacuation unit and the monitoring unit. The inventionfurther discloses an alarm and a positioning method of the leakage point based on the alarm system for the indoor gas leakage. The positioning method comprises the following steps of: S1, collectingsignals of the gas concentration; S2, obtaining the concentration change data, and transmitting the date to a controller timing; S3, establishing an indoor two-dimensional coordinate diagram, to display the concentration change data; S4, sending an alarm and the alarm information while an abnormal node exists, thereby realizing the positioning of the leakage point; S5, opening a ventilation fan and a fire sprinkler, thereby achieving the gas evacuation. According to the alarm system for the indoor gas leakage and the alarm thereof, and the positioning method of the leakage point, the problemsin the prior art that the adaptability is poor; that the practicability, the timeliness, and the maintenance efficiency is low; that the workload is large; and that the personal safety of the threat maintenance personnel is high are solved.
Description
technical field [0001] The invention belongs to the technical field of gas safety, and in particular relates to an indoor gas leakage alarm system and an alarm and leakage point locating method. Background technique [0002] Gas is the general term for gas fuel. It can burn and release heat for use by urban residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas and biogas. In recent years, it has become a clean, efficient and cheap With the rapid development of energy and natural gas consumption, gas is used more and more widely in residents' daily life. In addition to traditional cooking, there are also heating, bathing and so on. For various reasons, during the use of gas, there are often accidents, such as the leakage of gas that causes the concentration of gas in the room to be too high, resulting in an explosion, etc., which brings great harm or hidden dangers to people's daily life. [0003] At pr...
