Device for centralized monitoring and warning of civil gas leak

Abstract

The invention discloses a device for centralized monitoring and warning of civil gas leak, comprising a detection pipeline, a pipeline exhaust device, home user terminals and a main monitoring device. The device is characterized in that: each home user terminal and the main monitoring device are connected through the detection pipeline; signal control and electric power supply are carried out on the each user terminal through multi-core wires laid along the pipeline by utilizing the main monitoring device; a main control signal receiving and processing module, a detecting gas transporting and controlling module and a warning module are arranged at the each home user terminal; and the main monitoring device comprises an air extracting device and a gas detecting sensor and a centralized control module which are arranged at the tail end of the detection pipeline and a wireless signal sending module. The device provided by the invention has the advantages of greatly reducing the one-family prior-period input and maintenance cost of a gas monitoring and warning system for home users; effectively improving the reliability and the accuracy of monitoring the gas leak; benefiting of realizing the specialized maintenance management of the monitoring and warning system; and timely finding and effectively handling problems.

Description

technical field [0001] The invention relates to a gas leakage monitoring and alarm device, in particular to a centralized civil gas leakage monitoring and alarm device. Background technique [0002] With the development of the economy, more and more household users use piped gas, and there are more and more safety accidents caused by gas leakage. Once the gas leakage is not dealt with in a timely and effective manner, it will cause extremely serious consequences. At present, the proportion of home users purchasing and installing gas alarms is relatively small, mainly for the following three reasons: first, the price of gas alarms is high, and it is difficult to popularize; second, many civil gas alarms use some gas sensors, which have poor performance. The sensitivity and selectivity are not high, and there are many missed or false alarms in actual use; the third is that the sensitivity of the gas alarm needs to be checked regularly after installation. Most of the products r...

Problems solved by technology

[0002] With the development of the economy, more and more household users use pipeline gas, and there are more and more safety accidents caused by gas leakage. Once the gas leakage is not dealt with in a timely and effective manner, it will cause extremely serious consequences.

At present, the proportion of home users purchasing and installing gas alarms is relatively small, mainly for the following three reasons: first, the price of gas alarms is high, and it is difficult to popularize; second, many civil gas alarms use some gas sensors, which have poor performance. The sensitivity and selectivity are not high, and there are many missed or false alarms in actual use; the third is that the sensitivity of the gas alarm needs to be checked regularly after installation. Most of the products require a service life of within two years, and a new alarm needs to be purchased when it expires. device, which increases the user's use cost, and requires a monthly verification during the service period to ensure normal work. It is difficult for ordinary home users to carry out the verification as required

The above factors limit the popularization and use of gas safety monitoring alarms in civilian users

[0003] At present, users who have installed civil gas detection alarms usually use one or more gas sensors per household, and connect them to gas shut-off valves or exhaust fans for alarm processing linkage. Due to power consumption, many gas alarms require an external power supply For long-term unmanned users, the detection and alarm cannot be performed after the main switch of the home circuit is closed. Even if the battery is used for power supply, the same problem will exist after the battery runs out. Achieve daily real-time and effective monitoring and protection, especially for some unoccupied for a long time after the gas is turned on, lack of normal safety inspections, and the probability of problems is greater

[0004] At present, there is also a centralized alarm device that uses the bus to transmit the alarm signals of each household in the building to a centralized location for linkage alarm. This method still cannot solve the high cost of a single household and cannot be maintained in time when a failure occurs. At the same time, the reliability of the centralized alarm still depends on the quality of the alarm selected by the residents of the household, and the reliability and accuracy of the alarm are not high due to the cost acceptance of the residents.
