Abstract

The invention discloses a hazardous gas detection method and a hazardous gas detection device for a cable tunnel, and a helmet. The hazardous gas detection method comprises the steps that: a gas detector arranged on the helmet is used for detecting the environment to obtain gas data, and sends the gas data to terminal equipment, wherein the gas data at least comprise gas concentration of at leastone kind of the detected gas; and the terminal equipment sends an alarm prompt when determining that the environment contains a standard-exceeding dangerous gas according to the gas data. According tothe hazardous gas detection method and the hazardous gas detection device, the technical problem that the detection cost and the operation safety of the existing detection mode are mutually oppositein the prior art is solved.

Description

technical field [0001] The present application relates to the field of dangerous gas detection in cable tunnels, in particular, to a dangerous gas detection method and device for cable tunnels, and a helmet. Background technique [0002] At present, the detection method for dangerous gas in the cable trench is as follows: install detection instruments at multiple positions in the cable trench, and notify the operators of the gas safety situation in the cable trench through broadcasting. [0003] However, the above-mentioned detection method will lead to the following problems: if the installation density of the detection instrument is low, it will cause the operator to move to the dangerous area without knowing it. Large; if the installation density of testing instruments is high, the cost will rise sharply. [0004] Aiming at the technical problem that the detection cost and operation safety of the existing detection methods in the related art are opposed to each other, no...
