Embodiment 1

[0073] When the underground gas concentration exceeds the standard, such as Figure 7 shown, perform the following steps:

[0074] S11. Data collection: the composite gas detection sensor 8 installed on the robot body 3 transmits real-time underground gas concentration data to the data processing module 11;

[0075] S12, data processing: the data processing module 11 compares the real-time state data with the standard data transmitted by the memory module 14, and generates a comparison result and sends it to the main control module 12;

[0076] S13, early warning judgment: the main control module 12 performs early warning processing on the comparison result, when the gas concentration exceeds the early warning threshold, generates early warning information and enters step S14, and when the gas concentration does not exceed the early warning threshold, enters step S17;

[0077] S14, alarm judgment: the main control module 12 performs alarm processing on the comparison result, ...

Embodiment 2

[0082] When the downhole temperature is abnormal, such as Figure 8 shown, perform the following steps:

[0083] S21, data collection: the temperature sensor 7 arranged on the robot car body 3 collects downhole temperature data in real time and transmits the data processing module 11;

[0084] S22, data processing: the data processing module 11 compares the downhole temperature data with the standard temperature transmitted by the memory module 14, and generates a comparison result and sends it to the main control module 12;

[0085] S23, early warning judgment: the main control module 12 performs early warning processing on the comparison result, when the downhole temperature exceeds the early warning threshold, generates early warning information and enters step S24, and when the downhole temperature does not exceed the early warning threshold, enters step S27;

[0086] S24, alarm judgment: the main control module 12 performs alarm processing on the comparison result, when ...

Embodiment 3

[0091] When the downhole side wall stress is abnormal, such as Figure 9 shown, perform the following steps:

[0092] S31, data acquisition: the optical fiber sensor 9 arranged on the robot body 3 collects downhole stress data in real time and transmits the data processing module 11;

[0093] S32, data processing: the data processing module 11 compares the downhole stress data with the standard stress transmitted by the memory module 14, and generates a comparison result and sends it to the main control module 12;

[0094] S33, early warning judgment: the main control module 12 performs early warning processing on the comparison result, when the downhole stress data exceeds the early warning threshold, generates early warning information and enters step S34, and when the downhole stress data does not exceed the early warning threshold, enters step S37;

[0095] S34, alarm judgment: the main control module 12 performs alarm processing on the comparison result, when the downhol...

Abstract

The invention discloses an intelligent inspection system for downholes. The intelligent inspection system comprises a flexible guide rail (2), a robot trolley (3), a light source (5), a camera (6), atemperature sensor (7), a composite gas detection sensor (8), an optical fiber sensor (9), a data processing module (11), a master control module (12), a storage module (14), a central control system(16), a data receiving module (4), a data transmitting module (13) and a power module (15). The flexible guide rail (2) is fixedly arranged on an in-pit side wall (1) and guides the robot trolley (3).The robot trolley (3) is used for carrying a detection module, the data processing module and the control module, and is arranged on the flexible guide rail (2). The light source (5), the camera (6),the temperature sensor (7), the composite gas detection sensor (8) and the optical fiber sensor (9) are used for detecting data. The data processing module (11), the master control module (12), the storage module (14) and the central control system (16) are used for processing the detected data. The data receiving module (4) and the data transmitting module (13) are used for transmitting the data. The power module (15) is used for powering the robot trolley (3). The intelligent inspection system has the advantages that potential downhole safety hazards can be discovered timely, downhole safety can be improved, and detection cost is reduced.

Description

technical field [0001] The invention relates to the field of underground safety detection of coal mines, in particular to an intelligent inspection system for underground mines. Background technique [0002] At present, the country's requirements for safe production are getting higher and higher. The mines of coal production enterprises must install the following devices: personnel positioning system, communication system, image transmission monitoring system and gas monitoring system, but all these existing systems are mostly fixed in The single downhole system has the following problems: 1) It requires personnel to operate downhole, and the uphole cannot know the downhole field data in time; 2) The system has no tracking function, and there are too many dead ends; 3) Every time a system is installed, it needs to be repeated in the downhole Cabling, repeated installation of various hosts or system servers. Contents of the invention [0003] The present invention aims to ...
