Abstract
This invention relates to a kind of gas detection warning system; mostly include mainframe and sensing module that can freely connect this mainframe. This sensing module possesses parameter checking module which has parameter of adjusting and setting gas concentration and alert. this sensing module send corresponding signal to mainframe after detecting gas concentration; mainframe compare gas concentration with signal record value, while exceed default will give out corresponding caution, and by this to solve existing technical deletion.
Description
technical field [0001] The invention relates to a detection alarm technology, in particular to an alarm system applied to detection of gas. Background technique [0002] According to the general gas detection and alarm system, it can usually be used to detect gases such as flammable gases, toxic gases, or liquid gases, and issue corresponding alarms, thereby performing leakage monitoring, area monitoring, or personal protection. Related patented technologies such as the United States Patent Publication No. 3,879,717, US Patent Publication No. 4,112,356, US Patent Publication No. 4,175,422, US Patent Publication No. 5,280,273, etc. [0003] US Patent Publication No. 3,879,717 discloses a portable methane detection and alarm system, which is mainly designed to be powered by batteries for easy hand-holding, and uses semiconductor gas sensing components to detect the methane concentration, so as to issue an alarm when the methane concentration reaches a predetermined value.
