By adopting the embodiment, in the actual gas monitoring process, the current gas concentration collected by each monitoring point in the tunnel is respectively compared with the preset concentration threshold value, whether the current gas concentration of each monitoring point is greater than or equal to the preset concentration threshold value or not is judged, and if the current gas concentration of the monitoring point is greater than or equal to the preset concentration threshold value, a first alarm signal is sent according to the position information of the monitoring point, so that the site personnel of the monitoring point are reminded in time, and the safety of tunnel construction is improved; if the current gas concentration of the monitoring point is smaller than the preset concentration threshold, the concentration difference value between the current gas concentration of the monitoring point and the preset concentration threshold is calculated, based on a preset mapping table, the concentration difference value section to which the concentration difference value belongs is selected, the corresponding preset sampling frequency is determined, the current sampling frequency corresponding to the monitoring point is updated to be the preset sampling frequency, and the gas concentration of the corresponding monitoring point is resampled according to the preset sampling frequency, so that the sampling requirements of the monitoring points with different gas concentrations are met, the dynamic adjustment of the sampling frequencies of different monitoring points is realized, the situation that part of the concentration information of the monitoring points is not obtained timely or part of the system resources of the monitoring points are wasted is reduced, and the adaptability of the gas monitoring system is improved.
It should be noted that in the actual monitoring process, because the length of the construction section in the tunnel is long, a plurality of monitoring points are arranged in the tunnel, each monitoring point is provided with a gas concentration acquisition module, and the gas concentration of the corresponding monitoring point is acquired by each gas concentration acquisition module, so that the gas concentration distribution condition in the tunnel can be known in real time conveniently; in addition, the distance between each monitoring point can be determined according to actual factors such as the section area in the tunnel, the construction environment and the like.

As an implementation way for acquiring the position information of the monitoring points, each monitoring point is provided with a GPS positioning module, and the position information of each monitoring point can be acquired by positioning each GPS positioning module; by obtaining the position information of each monitoring point, the position of a certain monitoring point can be quickly and accurately determined when the gas concentration of the monitoring point exceeds the standard or the ventilation parameter is abnormal, and a countermeasure can be timely taken.
As an embodiment of calculating a concentration difference value between the current gas concentration of the monitoring point and a preset concentration threshold, the concentration difference value is a difference between the current gas concentration and the preset concentration threshold, and the concentration difference value is always greater than or equal to 0; for example, if the current gas concentration at the monitoring point is 0.3% and the preset concentration threshold is 1%, the corresponding concentration difference is 0.7%.
As an embodiment of determining the corresponding preset sampling frequency based on the preset mapping table and the concentration difference value, the preset mapping table includes a plurality of sets of corresponding relationships between concentration difference value intervals and the preset sampling frequency, each concentration difference value interval has no intersection, and each concentration difference value interval corresponds to one preset sampling frequency; for example, the concentration difference interval is [ D1, D2 ] corresponding to the preset sampling frequency f1, and the concentration difference interval is [ D2, D3] corresponding to the preset sampling frequency f 2; if the calculated concentration difference value D is within [ D1, D2 ], determining that the preset sampling frequency corresponding to the concentration difference value is f 1; if the calculated concentration difference value D is within [ D2, D3], determining that the preset sampling frequency corresponding to the concentration difference value is f 2; wherein D1, D2 and D3 are all greater than or equal to 0, D3> D2> D1, and f1> f 2. Therefore, if the difference value between the current gas concentration and the preset concentration threshold value is judged to be larger, sampling can be carried out by adopting a lower sampling frequency, so that the waste of system resources is reduced; if the difference value between the current gas concentration and the preset concentration threshold value is judged to be small, sampling can be carried out by adopting a high sampling frequency, so that the gas concentration information can be obtained in time, and the monitoring safety is improved.
The preset sampling frequency is the optimal sampling frequency when the concentration difference value is in the concentration difference value interval, and the optimal sampling frequency can be obtained by combining historical monitoring data; in addition, in the actual monitoring process, the opening and closing of the end points of each concentration difference interval, the length of each concentration difference interval and the number of the concentration difference intervals can be set and adjusted according to the actual situation.
As an implementation way of updating the current sampling frequency corresponding to the monitoring point to the preset sampling frequency, the current sampling frequency is adjusted to the preset sampling frequency, and then the gas concentration of the corresponding monitoring point can be resampled according to the preset sampling frequency.
