[0005] In the process of realizing the present invention, the applicant found that the prior art has the following technical defects: the data between the multiple sensors of the sensing control subsystem has correlation, so the data reported to the information integration layer has a large amount of data redundancy. In addition, it often causes urgent data to be unable to be transmitted to the upper computer of the information integration layer in time

example 1
[0088] Example 1: The gas concentration in a certain place exceeds the limit, the CO is normal, the ventilation is normal, and the smoke is normal. Get the Model 1 = 22, to describe and monitor hazards;
[0089] Measure the normal water level, normal flow, normal flow velocity, Modle 1 abnormal. Get the Model 2 = 16, to describe and monitor hazards;
[0090] It is measured that the roof pressure and rockburst pressure are normal, located in the air return lane, Modle 2 abnormal. Get the Model 3 = 8, indicating that this place is normal;
[0091] Modle 4 、Model 5 normal. It means that this place is normal, and it may be located in a position with high gas such as the return air lane.
example 2
[0092] Example 2: The gas concentration in a certain place exceeds the limit, the CO is normal, the ventilation is normal, and the smoke is normal. Get the Model 1 = 22, to describe and monitor hazards;
[0093] Measure the normal water level, normal flow, normal flow velocity, Modle 1 abnormal. Get the Model 2 = 26, to describe and monitor hazards;
[0094] Measure the overrun of the roof pressure and the overrun of the rockburst, located in the fully mechanized mining face, Modle 2 abnormal. Get the Model 3 = 28, indicating that the place is moderately dangerous, the gas concentration is high, and gas outburst accidents may occur;
[0095] It is measured that the temperature is high, the humidity is low, the population density is high, and the Modle 3 abnormal. Get the Model 3 =39, indicating that the place is seriously dangerous;
[0096] It is dangerous to measure the historical results of this place, to predict the danger, the artificial control is poor, and Mo...

Abstract
The invention provides a danger source monitoring system for mines. The system comprises sensor acquisition equipment, data fusion equipment and sensor network routing equipment, wherein the sensor acquisition equipment comprises one or more sensors and is used for acquiring data of the sensors; the data fusion equipment is used for performing stepwise assessment on risk assessment models (with different levels) subjected to sensor data application pre-storage from a high-danger level to a low-danger level, and when one assessment result is equal to or higher than a preset danger level, the assessment result is uploaded corresponding to the sensor data related to the danger level; and the sensor network routing equipment is used for receiving the sensor data uploaded by a plurality of data fusion equipment and routing the sensor data to an upper computer according to a sequence from a high danger level to a low danger level. According to the system, results are rapidly calculated during major danger source monitoring by using a plurality of key factor data, so that urgent data can be timely transmitted to the upper computer.
Description
technical field [0001] The invention relates to the technical field of mine safety production, in particular to a mine hazard source monitoring system. Background technique [0002] It has become the consensus of those skilled in the art that single sensor monitoring reliability is poor in coal mine hazard source monitoring and early warning. The multi-sensor fuzzy data fusion technology is applied to the coal mine hazard source monitoring and early warning system, and multiple sensors are selected to comprehensively monitor the abnormal information underground, which can make up for the shortcomings of using a single type and single sensor, and expand the monitoring range in time and space . According to the real-time data and historical data monitored by the sensors of the monitoring system, each subsystem analyzes and judges according to different models, respectively gives early warning levels and adopts engineering technology or organizational management measures to re...
