Problems solved by technology

The relatively advanced pipeline gas leakage alarm can automatically alarm and automatically close the pipeline gas valve, but it cannot know the concentration range of carbon monoxide in the gas leakage area
In this way, it is possible to mishandle the leaked gas incident after discovering the pipeline gas leak, resulting in follow-up processing accidents.

Embodiment

[0014] The pipeline gas intelligent automatic manager of the present invention is composed of a gas leakage alarm, an electromagnetic valve cut-off device on a gas delivery pipe, a CPU single-chip microcomputer control circuit, a power management chip, an alarm signal input interface circuit and a power supply circuit. The implementation of the pipeline gas intelligent automatic manager of the present invention is mainly to assemble the gas leakage alarm and the electromagnetic valve disconnector together, and the low power consumption single-chip microcomputer in the manager is matched with software to work to control the system. At the same time, the sensitivity of the carbon monoxide concentration sensor in the siren is set to low, medium and high levels, which correspond to the warning chirps or voice prompts of the siren, indicating the slight, medium and serious leakage degrees of the carbon monoxide concentration range in the gas leakage area. The power management chip i...

Abstract

The invention discloses an intelligent and automatic piped gas manager which is mainly assembled by a gas leakage alarm and an electromagnetic valve amputator, and the manger system operates in a way that a microprocessor control circuit is equipped with software. The sensitivity of a concentration sensor for carbon monoxide in the alarm is set into three grades, namely, low grade, medium grade and high grade, which are matched with chime or voice prompt of the alarm and indicate mild, medium or serious degrees and the like. When the concentration of leaking carbon monoxide exceeds the set value of the alarm, the alarm gives off one of different chimes or voice prompts matched with three types of carbon monoxide concentrations. Thus, the range of the leaking gas concentration as well as leaking seriousness can be known and correct measures can be taken timely to follow the post scientific treatment. If left unattended, the automatic manger automatically turns off the alarm and the electromagnetic valve so as to realize high-performance intelligent reliable management of the leaking alarm and automatic disconnection of piped gas.

Description

technical field [0001] The invention relates to an intelligent automatic manager for pipeline gas that can measure the concentration of carbon monoxide in leaked gas, set the concentration to the third range and sound an alarm, and automatically close the switch of the pipeline gas electromagnetic valve at regular intervals. Background technique [0002] Piped gas has been widely used in modern families. However, the resulting pipeline gas carbon monoxide leakage poisoning incidents occur frequently. Tracing it to its cause is mainly because people lack safety consciousness, operate improperly, or after gas is used, forget to close pipeline gas valve. For public safety and loss of life and property, it is necessary to install pipeline gas leakage alarm and cut-off device to prevent problems before they happen. But, in fact, many families that use pipeline gas often do not install gas leakage alarm, or only simple gas leakage alarm is installed. In this way, after the gas ...
