Embodiment Construction

[0026] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The invention provides a method for monitoring tunnel gas, the method comprising the following steps:

[0028] Detecting the gas concentration in the tunnel to obtain the gas concentration in the tunnel;

[0029] Comparing the concentration of the gas with a predetermined concentration, when the concentration is greater than the predetermined concentration, a wattage blocking signal is issued;

[0030] Receive the wattage lock signal, automatically cut off the power from the...

Abstract

The invention relates to the field of tunnel monitor and particularly relates to a monitoring method of tunnel gas. The monitoring method can be used for shortening the processing time. The monitoring method of the tunnel gas comprises the following steps of: detecting the concentration of the gas in a tunnel to obtain a concentration value of the gas in the tunnel; comparing the concentration of the gas with a preset concentration with a preset concentration, and sending out a gas-electricity locking signal when the concentration of the gas is greater than the preset concentration; receiving the gas-electricity locking signal, automatically cutting off electricity at a total control switch, and sending an alarm; and after the total control switch is cut off, and when the concentration of the gas is less than the preset concentration, controlling the total control switch to be switched to a be power-on state.

Description

technical field [0001] The invention relates to the field of tunnel monitoring, in particular to a method for monitoring tunnel gas. Background technique [0002] When mining a tunnel, in order to ensure construction safety, the gas content in the tunnel will be monitored. [0003] At present, the methane detector is used to monitor the gas content in the tunnel. The gas content in the tunnel is detected by the methane detector, and the detected gas content higher than the set value is uploaded, and an alarm is issued, and the control personnel cut off the power supply. [0004] However, after detecting that the gas content is too high, the information is uploaded, and then the control personnel cut off the power supply, which takes a long time to process, and other safety accidents caused by electricity are likely to occur during this period. Contents of the invention [0005] The invention provides a tunnel gas monitoring method, which can shorten the processing time. ...
