In one embodiment, the reminding instruction containing the traffic state of the underground roadway can be sent to a mobile terminal (such as a mobile phone), or sent to a server, and then sent to the mobile terminal through the server, so as to realize the reminding of the target object holding the mobile terminal.
Therefore, the traffic control system of the coal mine underground roadway can intelligently manage and control pedestrians and vehicles close to the coal mine underground roadway by combining the wireless communication technology and the infrared image sensing technology, avoid major traffic accidents, and guarantee the safety of the running vehicles and the pedestrians.
It is understood that before the acquisition of the proximity information of the target object, the acquisition of the whole image information of the target area where the target object is located needs to be performed, and the image information is identified, so that the target object in the image information is judged to be a pedestrian or a vehicle for subsequent processing, and the acquisition efficiency is improved by determining the acquired target object in advance.
In some embodiments, the information acquisition component 10011, as shown in fig. 2, further comprises: an image acquisition unit 100112; an image acquisition unit 100112 for: before the positioning unit 100111 acquires the proximity information of the target object, image information in the target area is acquired, and the information processing component 10012 determines that the target object is included in the image information.

The person in the art can understand that different from common cameras, infrared cameras such as infrared thermal imagers and the like, the infrared camera can illuminate the shot object by emitting infrared light which cannot be seen by human eyes, so that the object under a night scene can be clearly shot, and the detection of pedestrians and vehicles approaching a coal mine underground roadway at night is met.
Especially, take infrared thermal imaging as an example, because human body surface has the heat to give off, and the in-process of vehicle operation, parts such as engine all can generate heat, from this, this application is based on the thermal imaging principle, can gather and discern the heat that vehicle and/or pedestrian sent that is close underworkings to avoided underworkings light line spare relatively poor image information acquisition lower technical problem of accuracy that leads to, laid a good foundation for accurately acquireing the approximate information of target object.
Optionally, a video analysis device may be additionally provided to be combined with the infrared camera, and the image information may be more accurately acquired by analyzing the video captured by the infrared camera.
Therefore, the traffic control system of the underground coal mine roadway can avoid the interference of non-target objects which are not in the roadway but in the acquisition range, shortens the working time and improves the working efficiency.
Further, after the image acquisition unit 100112 acquires the image information in the target area, the information processing component 10012 determines the acquired image information, that is, determines whether the image information contains the target object.
It should be noted that after it is determined that the image information contains the target object, the target object may be further identified, for example, the type of the target object is determined, that is, the target object is determined to be a pedestrian or a vehicle, and information that the target object approaches the underground roadway of the coal mine is acquired, so that a corresponding reminder is selected according to the approach information.
In some embodiments, the information processing component 10012 is further configured to: acquiring the type of a target object; acquiring a target proximity information threshold corresponding to a target object according to the type; and judging whether the proximity information of the target object is smaller than the corresponding target proximity information threshold value or not, and generating a matched reminding instruction according to the judgment result.
It should be noted that the type of the target object may specifically include at least one of the following: the information processing component 10012 may determine the type of the target object included in the image information by identifying the type of the target object from the collected image information, and generate a corresponding reminding instruction according to the proximity information of the target object to remind the target object.
In the present application, the specific manner of acquiring the type of the target object is not limited, and may be set according to actual situations.
In one embodiment, the positioning unit 100111 can be combined with an identification card, and different target objects wear different identification cards, in which case, by identifying the identification card of the target object, the type of the target object can be determined.
In one embodiment, different types of target objects may be configured to wear different UWB tags, and in this case, the type of the target object may be identified according to the UWB tag of the target object.
In one embodiment, the material of the target object or the material of the equipment to be worn may be different, and thus the reflectivity of the electromagnetic wave may be different.
Further, the information processing component 10012 may obtain the corresponding target proximity information threshold according to the type of the target object, for example, when the target object type is a pedestrian, the corresponding target proximity information threshold is a pedestrian proximity information threshold, and when the target object type is a vehicle, the corresponding target proximity information threshold is a vehicle proximity information threshold.
The present application is not limited to a specific manner of obtaining the corresponding target proximity information threshold according to the type of the target object, and may be set according to actual situations.
In an embodiment, a mapping relationship table of the type of the target object and the target proximity information threshold may be established in advance, and the target proximity information threshold corresponding to the type of the target object is searched and obtained in the mapping relationship table according to the known type of the target object.
It should be noted that the type of the target object corresponds to the target proximity information threshold one to one, and the target proximity information threshold may be set according to an actual situation, which is not limited in this application.
And further, comparing the proximity information of the target object with a target proximity information threshold value, and generating a corresponding reminding instruction according to a comparison result. For example, when the target object is a pedestrian and the approach information of the pedestrian is smaller than the threshold value of the approach information of the pedestrian, the corresponding reminding instruction is that the pedestrian passes through the roadway and please wait, otherwise, the corresponding reminding instruction is normal traffic; when the target object is a vehicle and the approach information of the vehicle is smaller than the vehicle approach information threshold value, the corresponding reminding instruction is 'the vehicle passes through the roadway and please wait', otherwise, the corresponding reminding instruction is 'normal pass'.
In some embodiments, when the system includes a traffic control device, the information processing component 10012 is further configured to: when the approach information is determined to be larger than or equal to the target approach information threshold value, generating a first reminding instruction for indicating that no target object passes in the underground roadway and sending the first reminding instruction to the indicator lamp, so that the indicator lamp emits green light according to the first reminding instruction; and when the proximity information is determined to be smaller than the target proximity information threshold value, generating a second reminding instruction for indicating that a target object passes in the underground roadway and sending the second reminding instruction to the indicating lamp, so that the indicating lamp emits red light according to the second reminding instruction.
It should be noted that, the reminding instruction corresponds to the color of the indicator light, and different reminding instructions correspond to different colors of the indicator light. Optionally, the color display of the indicator light can be controlled by the control device and the driving device according to the reminding instruction. When the approach information is larger than or equal to the target approach information threshold value, namely no target object passes in the underground roadway, the indicator light is green light, and conversely, the indicator light is red light.
It should be noted that, this is taken as an example in the present application, but the corresponding relationship between the color of the indicator light and the reminding instruction is not limited too much, and the two can freely correspond to each other according to the actual situation.
The traffic control system of colliery underworkings that this application provided can be applicable to all districts in underworkings, especially, often has more apparent effect to special district.
The special section may include, but is not limited to, any of the following sections: narrow roadways, sharp-turn roads, crossroads and other sections.
For example, the scene of narrow roadway and sharp turn road near the underground roadway of coal mine as shown in fig. 3 and fig. 4 comprises a control device a and a control device B, and the adjacent control devices are connected through optical fibers or network cables.
Taking the control device a as an example for explanation, when the type of the target object is a pedestrian, if the pedestrian approach information acquired by the control device a is smaller than the approach information threshold value and the infrared camera detects the infrared information source of the pedestrian, the control device a sends control information to the control device B, and the control device B controls the reminding component to carry out corresponding reminding.
Similarly, when the type of the target object is a vehicle, if the vehicle approach information acquired by the control device A is smaller than the approach information threshold value and the infrared camera detects the infrared information source of the vehicle, the control device A sends control information to the control device B, and the control device B controls the reminding assembly to correspondingly remind.
In some embodiments, the information processing component 10012 is further configured to: when the proximity information is determined to be smaller than the target proximity information threshold value, whether the information acquisition assembly acquires the proximity information of other objects is judged; after the information acquisition assembly is determined to acquire the approaching information of other objects, a third reminding instruction for reminding the other objects to slowly move is generated and sent to the indicating lamp, so that the indicating lamp emits yellow light according to the third reminding instruction.
It is understood that after a target object enters from one of the entrances of the roadway, there may be a possibility that other target objects continue to enter from the same entrance, and then a reminder needs to be given to the target object entering later, for example, to slow down, to keep a distance from the leading vehicle, and so on.
It should be noted that there may be a plurality of target objects, and the traffic control system 1000 of the coal mine underground roadway may have a plurality of traffic control devices, so that in the present application, it may be determined whether there is proximity information of other corresponding objects collected by the information collecting component of any other traffic control device, so as to remind the target object through the traffic control device corresponding to the target object according to the determination result.
It should be further noted that when the information acquisition component acquires the approach information of other objects, the control indicator lamp displays a yellow lamp to remind the other objects to slow down and pass slowly.
In some embodiments, when the system includes at least two traffic control devices disposed at different entrances to the downhole roadway, the information processing component 10012 is further configured to: and responding to the fact that the reminding component corresponding to any other traffic control equipment sends out reminding, directly generating a second reminding instruction and sending the second reminding instruction to the indicating lamp, so that the indicating lamp sends out red light according to the second reminding instruction.
It should be noted that when any other object triggers the reminding of the traffic control device, the current object needs to stop passing, that is, the indicator light is directly controlled to display red color to remind the current object to stop passing.
For example, the scene close to the intersection of the underground roadways of the coal mines shown in fig. 5 includes a control device a, a control device B, a control device C and a control device D, and the adjacent control devices are connected through optical fibers or network cables.
Taking the control device a as an example for explanation, when the type of the target object is a pedestrian, if the pedestrian approach information acquired by the control device a is smaller than the approach information threshold value and the infrared camera detects the infrared information source of the pedestrian, the control device a sends control information to the control device C and the control device D, and the control device C and the control device D control the reminding assembly to carry out corresponding reminding.
Similarly, when the type of the target object is a vehicle, if the vehicle approach information acquired by the control device A is smaller than the approach information threshold value and the infrared camera detects an infrared information source of the vehicle, the control device A sends control information to the control device C and the control device D, and the control device C and the control device D control the reminding component to carry out corresponding reminding.

Those skilled in the art can understand that, because the information collection assembly 10011 has the characteristic of wide collection range, in this case, in order to improve the accuracy of collection, and prevent the interference of the explosion-proof assembly 10014 to the collection process, the information collection assembly 10011 can be set outside the coverage of the explosion-proof assembly 10014, and the information processing assembly 10012 and the reminding assembly 10013 are set inside the coverage of the explosion-proof assembly 10014, so as to ensure the normal operation of the assembly and the accuracy of the collection result on the basis of protecting the device.
It should be noted that the specific structure of the flameproof component can be set according to actual conditions, and the application does not limit the specific structure.
As a possible implementation manner, the explosion-proof assembly may be an assembly having only one layer of explosion-proof housing.
As another possible implementation manner, the explosion-proof assembly may be divided into a plurality of parts. For example, the explosion-proof assembly can be divided into two parts, wherein the top part is an explosion-proof cover, and the rest part is an explosion-proof shell.
Further, the light transmittance of the shell of the explosion-proof component can be further limited.
For example, the flameproof housing can be divided into a light-transmitting area and a light-proof area; wherein, the light transmission area is composed of a light transmission surface, and the light non-transmission area is a non-light transmission metal explosion-proof surface.
Therefore, the traffic control system of the coal mine underground roadway can intelligently control pedestrians and vehicles close to the coal mine underground roadway, avoid major traffic accidents, and guarantee safety of driving vehicles and pedestrians.
