Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the prior art, cameras are usually installed and then monitored by staff observing camera images. When a person breaks in, the processing equipment is stopped. However, the staff's work is complicated and real-time supervision cannot be guaranteed. At the same time, visibility is poor during nighttime production, and staff cannot make accurate judgments, resulting in an increase in the accident rate. There is also a method of automatically identifying people approaching the processing equipment through cameras and sending alarms. However, the on-site environment is complex and the camera is prone to misjudgment. Frequent alarms not only cause frequent shutdowns of processing equipment and reduce production efficiency, but also make the staff feel numb and unable to carry out real-time supervision, resulting in an increase in the accident rate.
[0031] In order to solve the above problems, the utility model proposes an alarm device 100 for processing equipment. Figure 1 , Figure 2 and Figure 3 The alarm device 100 of the processing equipment includes a control station 1, a camera assembly 2 and an alarm host 3. The control station 1 is electrically connected to the processing equipment 5 and is used to control the start and stop of the processing equipment 5; the camera assembly 2 includes a main camera 20 and a plurality of sub-cameras 22 arranged around the main camera 20. The area photographed by the main camera 20 is the main camera area, and the area photographed by each sub-camera 22 is the sub-camera area. The main camera area covers the processing equipment 5 and the area close to the periphery of the processing equipment 5. Each sub-camera area is arranged around the main camera area, and there is an overlapping area 24 with the main camera area 21; the camera assembly 2 and the control station 1 are both electrically connected to the alarm host 3. The alarm host 3 is used to send a stop signal to the control station 1 when the target image appears in any sub-camera area 23 and the main camera area 21 in sequence, and control the processing equipment 5 to stop through the control station 1.
[0032] It can be understood that the secondary camera 22 can be set around the main camera 20 to achieve all-round coverage, but in general, it is usually necessary to reserve one side for unloading, etc. Therefore, the secondary camera 22 can be set in three directions of the main camera 20. The secondary camera 22 can also be set on both sides of the main camera 20 by closing one side of the processing equipment 5 through walls, etc., thereby reducing the movable range of personnel.
[0033] The technical solution of the utility model is to cover the processing equipment 5 and the area around the processing equipment 5 in the main camera area 21 of the main camera 20, and then set a plurality of sub-cameras 22 in the circumferential direction of the main camera 20. When a target image appears in the image of the sub-camera area 23, such as an image of a person entering the sub-camera area, the sub-camera 22 sends a sub-alarm signal to the alarm host 3. Subsequently, when the person close to the processing equipment continues to break into the main camera area 21, the main camera 20 captures the target image, such as the person entering the main camera area, and sends a main alarm signal to the alarm host 3. When the alarm host 3 receives the sub-alarm signal and the main alarm signal in sequence, it sends a shutdown signal to the control station 1, and the control station 1 controls the processing equipment 5 to shut down. The alarm device for processing equipment of the utility model can send a shutdown signal to the alarm host 3 only when both the main camera area 21 and the auxiliary camera area 23 have captured the target image, thereby performing double judgment and controlling the shutdown of the processing equipment 5 through the cooperation of the main camera 20 and the auxiliary camera 22, with high accuracy, avoiding frequent alarms and frequent shutdowns that lead to insufficient production efficiency, thereby improving production efficiency. At the same time, the production equipment is shut down through the cooperation of the alarm host 3 and the controller, without the need for manual control by the staff, thus ensuring real-time supervision, improving the shutdown speed, and reducing the occurrence rate of safety accidents. In addition, there is an overlapping area 24 between the main camera area 21 and the auxiliary camera area 23, which provides early warning and provides sufficient reaction time to shut down the processing equipment 5, further reducing the occurrence rate of accidents.
[0034] In one embodiment, the alarm device 100 also includes a fence 4 arranged on one side of the processing equipment 5, the fence 4 completely blocks one side of the processing equipment 5, and a plurality of sub-cameras 22 are arranged at intervals along the extension direction of the fence 4, and the shooting end of each sub-camera 22 faces the processing equipment 5.
[0035] By shielding one side of the processing equipment 5 with the fence 4, personnel cannot break in from the shielded side, thereby reducing the activity space of personnel and improving safety. At the same time, the number of secondary cameras 22 can be reduced, saving costs and reducing the difficulty of monitoring.
[0036] Furthermore, there are two auxiliary cameras 22, which are respectively arranged on both sides of the main camera 20. The main camera 20 is arranged directly above the processing equipment 5, and the shooting end of each auxiliary camera 22 is arranged downward. The side of the processing device away from the fence 4 is used as the side for the staff to move and unload materials. Therefore, it is only necessary to arrange auxiliary cameras 22 on both sides of the main camera 20 along the extension direction of the fence 4. The main camera 20 is located directly above the processing equipment 5, thereby covering the processing equipment 5, and making the camera range on both sides of the processing equipment 5 the same, so that the personnel close to the processing equipment on both sides can be found in a safe range sufficient for the processing equipment 5 to stop, thereby improving safety.
[0037] In one embodiment, the processing equipment 5 is located in the middle of the fence 4, and the alarm host 3 and the control station 1 are both arranged on one side of the fence 4 and spaced apart from the fence 4. The processing equipment 5 is located in the middle of the fence 4, and the alarm host 3 and the control station 1 are arranged on one side of the fence 4, so that there is a certain distance between the processing equipment 5 and the alarm host 3 and the control station 1, reducing the construction difficulty of the wiring, and ensuring that the staff and the processing equipment 5 maintain a safe distance.
[0038] In one embodiment, a plurality of alarm modules 41 are arranged at intervals on the fence 4 along its extension direction, and the alarm modules 41 are electrically connected to the alarm host 3. The alarm host 3 is used to control the alarm module 41 to alarm when the target image appears in sequence in any of the secondary camera areas 23 and the main camera area 21. When the target image appears in sequence in any of the secondary camera areas 23 and the main camera area 21, an alarm is sounded, and a warning is issued to personnel and staff near the processing equipment, so that the personnel near the processing equipment can find danger in time, and the staff can deal with the personnel near the processing equipment in time, thereby improving safety.
[0039] Specifically, the alarm module 41 includes a speaker and a flashing light. The speaker and the flashing light realize visual and auditory alarms at the same time, which increases the probability that the staff and the people near the processing equipment will find the alarm, and at the same time has a stronger sense of urgency, which increases the possibility of stopping the people near the processing equipment from going further.
[0040] Specifically, the height of the secondary camera 22 is 2.5m to 3m, the height of the main camera 20 is 3m to 3.5m, the fence 4 extends along the first direction, and the width along the first direction is 7m to 8m, the width of the secondary camera area 23 along the first direction is 7m to 8m, and the width of the overlapping area 24 of the main camera area 21 and the secondary camera area 23 along the first direction is 1.5m to 2m. The main camera 20 and the secondary camera 22 with the above height and camera range can ensure that a sufficient safety range is covered, leaving reaction time for shutdowns and time for staff to block people approaching the processing equipment, ensuring safety while reducing the number of shutdowns and improving production efficiency.
[0041] In one embodiment, a communication module is also provided on the alarm host 3, and the alarm host 3 is used to control the communication module to send an alarm message to the client when the target image appears in any of the secondary camera area 23 and the main camera area 21. The client can be any device with real-time communication function such as a computer, a mobile phone, a tablet, etc. After finding that the personnel close to the processing equipment pass through the secondary camera area 23 and the main camera area 21 in sequence, the alarm host 3 sends an alarm message to the client while sending a stop signal, so that the staff or the staff can rush to the site for processing in time, which improves safety and production efficiency.
[0042] The utility model also provides a processing system, including a processing device 5 and an alarm device 100 for the processing device as described above. The specific structure of the alarm device 100 for the processing device is referred to the above embodiment. Since the processing system adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0043] Furthermore, the processing equipment 5 is a crushing station, and the side of the processing equipment 5 facing away from the fence 4 is a discharge side for unloading by a discharge truck. The crushing station is an important equipment for continuous production in open-pit coal mines, and is used to crush raw coal into the required particle size. Therefore, it is necessary to discharge the material to the crushing station by a discharge truck. One side of the processing equipment 5 is shielded by the fence 4, and the other side is set as the discharge side. There are discharge trucks and staff at all times, so that people close to the processing equipment can only break in from both sides of the processing equipment 5 along the extension direction of the fence 4, which not only reduces the possibility of people breaking in, but also reduces the difficulty of monitoring and blocking, thereby improving safety.
[0044] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
