Compare in traditional manual driving, unmanned electric locomotive can satisfy the mining demand of mining environment complicated day by day, has stopped because of the accident that electric locomotive misoperation leads to, has improved production safety. Along with the unmanned scene of electric locomotive in the pit is more and more, the scene that people and car appear in a tunnel jointly can appear, needs the electric locomotive to have good obstacle avoidance function and early warning function this moment, but is limited by the environment in the pit, is difficult to dispose more positioning device and identification equipment, leads to the early warning performance of electric locomotive among the prior art still to be improved.
In order to solve the problems, the invention provides a safety early warning system for an electric locomotive and an early warning method thereof.
In order to facilitate understanding of the embodiment, first, a detailed description is given to a safety precaution system for an electric locomotive disclosed in the embodiment of the present invention, a schematic structural diagram of the system is shown in fig. 1, and the system includes:
an obstacle detection device 100 and a positioning device 200 deployed in an electric locomotive; the obstacle detection device 100 is used for detecting the distance between a roadway and an electric locomotive; the positioning device 200 is used for acquiring positioning data of the electric locomotive and determining a position coordinate of the electric locomotive according to the positioning data. Generally, the obstacle detection device 100 incorporates relevant radar devices, and implements distance measurement and detection of surrounding obstacles by receiving reflected waves emitted by the radar, and these radar devices are deployed around an electric locomotive, thereby enabling omnidirectional obstacle detection of the electric locomotive.
The positioning device 200 is deployed in an area with less shielding, such as the top end of an electric locomotive, because the electric locomotive works underground and the positioning signal is relatively weak, the positioning device needs to be deployed in the area with less shielding to better receive the positioning signal. The positioning protocol used by the positioning device 200 is different from the conventional GPS and other protocols, and the positioning device 200 needs to be combined with the corresponding positioning base station to realize positioning, so the safety precaution system further includes: the positioning base station 300 and the intelligent camera 400 are deployed in a preset area of a roadway; the positioning base station 300 is used for providing a positioning signal to the positioning device 200 of the electric locomotive; the intelligent camera 400 is used for detecting the distance between the personnel and the electric locomotive in real time through pattern recognition.
In some embodiments, the positioning base station 300 and the smart camera 400 are deployed in preset areas, which include: a personnel activity area, a curve area and a self-defining area. The positioning base stations 300 are deployed at corresponding positions of the roadway, that is, one positioning base station 300 is deployed at intervals in the roadway, and after deployment is completed, it can be ensured that all positions in the roadway can be covered by signals of the positioning base stations. The arrangement of the intelligent camera 400 can be determined according to actual requirements, and generally, the intelligent camera 400 is arranged at a higher position in a roadway so as to ensure the visual field; meanwhile, the intelligent camera 400 is deployed in an area with a high occurrence frequency of people and an area where an electric locomotive running path changes, such as a turning position of a roadway, a vein-crossing position, a joint with a large roadway and the like, as much as possible. The intelligent camera 400 performs pattern recognition on the personnel in the region with higher occurrence frequency of the personnel, performs pattern recognition on the electric locomotive, and can perform real-time detection on the distance between the personnel and the electric locomotive by utilizing the personnel coordinate and the electric locomotive coordinate obtained by recognition.
The detection result of the obstacle detection device 100, the positioning coordinate of the positioning device 200, and the detection result obtained by the intelligent camera 400 need to be judged in a relevant manner, so as to determine the risk of collision between the electric locomotive and the personnel and the roadway. Therefore, the safety precaution system further includes: a center console 500 and an alarm device 600; the center console 500 is used for determining the collision probability of the electric locomotive according to the detection result of the obstacle detection device 100 and the positioning coordinates of the positioning device 200; the central console is further used for determining the collision probability of the electric locomotive according to the real-time detection result of the intelligent camera 400.
Specifically, by using the detection result of the obstacle detection device 100 and the positioning coordinates of the positioning device 200, the surrounding roadway can be detected in real time in the driving process of the electric locomotive, so that the collision probability of the electric locomotive and the roadway is obtained; meanwhile, the collision probability between the electric locomotive and the personnel can be obtained by utilizing the real-time detection result of the intelligent camera 400. When the electric locomotive runs, the distance between the electric locomotive and the surrounding roadway is smaller, the probability of collision between the electric locomotive and the surrounding roadway is higher, and the risk of collision is higher; in a similar way, the smaller the distance between the electric locomotive and the personnel is, the greater the probability of collision between the electric locomotive and the personnel is, and the higher the risk of collision is. Generally, the risk of collision between the electric locomotive and the personnel is greater than the risk of collision between the electric locomotive and the roadway at the same distance, because the personnel also move, and once the moving direction is the direction of the electric locomotive, the collision is easier to occur.
The collision probability represents the driving safety of the electric locomotive, so that corresponding alarm equipment is needed to remind the electric locomotive or personnel when the safety is threatened, and the process is realized through the alarm device 600. The alarm device 600 is deployed in a roadway and connected with the central console 500; when the collision probability of the electric locomotive is greater than a preset collision threshold value, an alarm device in the roadway provides sound and light alarm signals.
In some embodiments, the obstacle detection device 100 includes: one or more of laser radar, millimeter wave radar and UWB radar; the positioning device 200 adopts one or more positioning protocols of TDOA, RFID, WIFI and ZIGBEE; the intelligent camera 400 is one or more of an infrared camera, a night vision camera and a binocular camera.
In some embodiments, the security precaution system further includes a location tag 700; the locator tag 700 is disposed in the person; the positioning tag 700 determines the positioning coordinates of the person through the positioning base station 300 and transmits the positioning coordinates to the center console 500 through the positioning base station 300. By deploying the positioning tag 700 in the person, the coordinates of the person can be determined by using the positioning base station 300, and the distance between the person and the electric locomotive can be determined from the positioning layer by combining the vehicle-mounted positioning device 200.
In some embodiments, the warning device 600 is also deployed in an electric locomotive; the alarm device 600 is connected with the center console 500 through a wireless protocol; when the collision probability of the electric locomotive is greater than the preset collision threshold value, the alarm device 600 in the electric locomotive provides an audible and visual alarm signal.
Can know through the safety precaution system who is used for the electric locomotive mentioned in the above-mentioned embodiment, the usable positioner of this system and location basic station acquire the position relation of personnel and electric locomotive from the angle of location, utilize intelligent camera to acquire the position relation of personnel and electric locomotive in real time from the angle of pattern recognition simultaneously, still utilize barrier detection device to acquire the position relation of personnel and electric locomotive from the angle of range finding, realized utilizing positioner simultaneously, many-sided safety precaution is carried out to electric locomotive to intelligent camera and barrier detection device, be favorable to promoting the early warning effect.
The embodiment also provides a safety early warning method for an electric locomotive, which is applied to the safety early warning system for an electric locomotive mentioned in the above embodiment, as shown in fig. 2, and the method includes:
step S201, a positioning device and a positioning base station in the safety early warning system are utilized to obtain the position coordinates of the electric locomotive.
The positioning device is installed in the electric locomotive, high-precision positioning of the electric locomotive is achieved through the positioning device and the positioning base station, and accurate coordinates of the electric locomotive can be achieved by combining position information of a roadway.
Step S202, acquiring the distance between the electric locomotive and a roadway in real time according to an obstacle detection device in the safety early warning system; and the distance between the electric locomotive and the personnel is obtained in real time according to the intelligent camera in the safety early warning system.
The driving direction track of the electric locomotive is detected in real time by using the related radar in the obstacle detection device, the distance between the electric locomotive and the roadway is obtained, and the distance between the roadway or the obstacle and the electric locomotive can be obtained by the obstacle detection device when the roadway changes or the obstacle appears.
The intelligent camera not only identifies the personnel, but also identifies the electric locomotive; and identifying the coordinate forms of the obtained personnel and the electric locomotive for representation, and finally determining the distance between the electric locomotive and the personnel according to the coordinate distance between the personnel and the electric locomotive.
And S203, sending the position coordinates of the electric locomotive, the roadway distance between the electric locomotive and the roadway and the personnel distance between the electric locomotive and the personnel to a central console of the safety early warning system.
The position coordinate of the electric locomotive is the position relation between the personnel and the electric locomotive obtained from the positioning angle; the roadway distance between the electric locomotive and the roadway is the position relation between the personnel and the electric locomotive obtained from the distance measurement angle; the person-to-person distance between the electric locomotive and the person is the position relationship between the person and the electric locomotive obtained from the viewpoint of pattern recognition. And sending the three types of data to a central console, and judging the early warning time of the electric locomotive by the central console.
Step S204, the central control console calculates the collision probability of the electric locomotive, the roadway and the personnel in real time according to the position coordinates of the electric locomotive, the roadway distance and the personnel distance; and when the collision probability is greater than the preset collision threshold value, the central console controls an alarm device in the safety early warning system to give an alarm.
The specific scene is as follows, when the electric locomotive goes to the region, the bend and the set region with the personnel, the electric locomotive is controlled to whistle at first, surrounding personnel are reminded to avoid in time, the running speed of the locomotive is limited at the same time, the safety factor of the personnel is improved, and meanwhile the central control console controls the alarm device to give an alarm.
In some embodiments, as shown in fig. 3, the method further comprises:
and S205, when the collision probability is greater than a preset collision threshold value, the central control console controls the electric locomotive to take braking measures and controls the electric locomotive to take whistle measures.
If the alarm is not released by the personnel within the set time, the running electric locomotive is automatically stopped. When the roadway distance is utilized to determine that the rail has obstacles or the electric locomotive is about to collide with the roadway, the central console controls the electric locomotive to take parking measures to avoid collision accidents.
Utilize personnel distance to judge the collision risk of personnel and electric locomotive, when personnel were close to the electric locomotive region of traveling, the electric locomotive took different counter measures such as deceleration, slow parking, stop immediately according to personnel distance.
In the processing process of an actual scene at a turning position and a junction of a drift and a main roadway, the positioning device and the positioning base station can acquire the position of the electric locomotive, and when the electric locomotive is close to a turning area, the electric locomotive is controlled to automatically perform whistling and deceleration processing; the positioning device and the positioning base station can also monitor the real-time distance between the personnel and the vehicle at the same time, and if the distance reaches a certain set value, the central console generates an alarm signal and provides the alarm signal for the alarm device. Utilize intelligent camera to obtain personnel's information in turn, juncture, in case detect that there is personnel's activity in the relevant region, then central console carries out real-time judgement with personnel and electric locomotive's distance. Therefore, the safety early warning method collects data from three aspects, realizes multi-aspect safety early warning on the electric locomotive by utilizing the positioning device, the intelligent camera and the obstacle detection device, and improves the early warning effect.
In some embodiments, the process of acquiring the distance between the electric locomotive and the person in real time by using the intelligent camera in the safety precaution system is implemented by using a relevant recognition model, as shown in fig. 4, including:
and S401, inputting the digital image acquired by the intelligent camera into the trained recognition model, and outputting the electric locomotive and the personnel contained in the digital image by using the recognition model.
The recognition model at least comprises two modules, namely: the system comprises an electric locomotive identification module and a personnel identification module; the electric locomotive identification module is used for identifying an electric locomotive in the digital image; the person identification module is used for identifying persons in the digital image. The two modules can be respectively two different recognition models, and the two recognition models are obtained by utilizing related artificial intelligence models to respectively train electric locomotives and personnel.
And S402, acquiring the external rectangle of the electric locomotive and the external rectangle of the personnel in the digital image in real time, and determining the distance between the external rectangle of the electric locomotive and the external rectangle of the personnel as the distance between the electric locomotive and the personnel.
The distance between the electric locomotive and the personnel in the digital image needs to be determined after the electric locomotive and the personnel are obtained, and because the shapes of the personnel and the electric locomotive are irregular, the external rectangles of the personnel and the electric locomotive are used as judgment bases for convenience in description. The circumscribed rectangle can be obtained by calculation through a related digital image processing algorithm, and is not repeated again.
After the external rectangle of the electric locomotive and the external rectangle of the personnel are obtained, the distance between the external rectangle and the personnel can be determined according to the coordinates of the central point of the external rectangle, and the distance between the external rectangle and the personnel can also be determined according to the shortest distance between the two external rectangles.
