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 will describe in detail with reference to the drawings and specific embodiments.

[0022] The embodiment of the present invention provides a portable poisonous gas alarm to solve the problem in the prior art that the alarm device cannot give timely alarms to operators or the alarms may be time-delayed in toxic environments. Such as figure 1 As shown, it is a schematic structural diagram of the toxic gas alarm provided by the 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 auditory alarm module 105. Wherein, the sensor has a toxic gas sensor for sensing the toxic gas content in the environment, and the obtained first A data is sent to the microprocessor 103 for processing. The microprocessor 103 includes: an ...

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 alarms, in particular to a portable poisonous gas alarm and an alarm method with the function of predicting and alarming by the least square method in a toxic gas environment. Background technique [0002] Leakage and release of toxic gases such as carbon monoxide often occur in industrial production. Operators face the risk of being directly exposed to toxic gas environments during work, and there is a risk of poisoning. The current solution is to equip operators with portable poisonous gas alarm devices. Operators carry alarm devices into dangerous environments. If the concentration of toxic gases exceeds a certain limit value, an audible and visual alarm will be issued to remind operators to stay away from the dangerous area. [0003] However, due to the certain response time of the toxic gas detector in the alarm device, when a sudden toxic gas leak occurs or the operator quickly enters the are...
