Embodiment Construction

[0021] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following detailed description will be given in conjunction with the accompanying drawings and specific embodiments.

[0022] The embodiments of the present invention provide a portable toxic gas alarm in view of the problems in the prior art that the alarm device cannot give timely alarms to operators or the alarms have time delays in a toxic environment. like figure 1 As shown, it is a schematic structural diagram of a poisonous gas alarm provided by an embodiment of the present invention. The toxic gas alarm includes: a sensor 101, a microprocessor 103, a timing module 102, a visual alarm module 104 and an audible alarm module 105. The sensor has a toxic gas sensor for sensing the toxic gas content in the environment, and the obtained No. A data is sent to the microprocessor 103 for processing. The microprocessor 103 incl...

Abstract

The invention provides a poisonous gas alarm. The alarm includes a sensor sensing content of poisonous gas, a timing module for timing, a microprocessor having least square method predication function, and a vision alarm module and an auditory alarm module sending alarm to operators according to indexes such as poisonous gas content change values, out-of-limit time points and the like. The invention solves a problem of time lag of a prior alarm. The alarm response speed and risk vigilance of people can be improved substantially. Human health damage is also reduced greatly by the early alarm function. Besides, due to the application of the least square method, error alarm possibility is reduced since the alarm has the predication function, so that the predication accuracy of the alarm is improved greatly.

Description

technical field [0001] The invention relates to the technical field of danger alarm, in particular to a portable toxic gas alarm and an alarm method with a least square method prediction alarm function in a toxic gas environment. Background technique [0002] In industrial production, the leakage and release of toxic gases such as carbon monoxide often occur, and operators face the risk of being directly exposed to toxic gases during work, and there is a danger of poisoning. The current solution is to equip the operator with a portable toxic gas alarm device. The operator enters the dangerous environment with the alarm device. If the concentration of toxic gas exceeds a certain limit, an audible and visual alarm will be issued to prompt the operator to stay away from the dangerous area. [0003] However, because the toxic gas detector in the alarm device has a certain response time, when a sudden toxic gas leak occurs or the operator quickly enters the high-concentration tox...
