[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] The core of the utility model is to provide a safety protection system, which can carry out real-time and effective all-round monitoring and protection, avoid operating errors of personnel, ensure the safe operation of equipment in the factory, and ensure the personal safety of personnel.

[0030] The safety protection system provided by the utility model includes a patrol module, a passage module, a warning module, and a host computer 5. Please refer to Figure 1 .

[0031] The inspection module includes an industrial camera 3, which is used to collect images of the post personnel 1 in all directions to determine their on-the-job behavior. The post personnel 1 is mainly used to supervise the normal and safe operation of the operating equipment 9. If the post personnel 1 has problems such as being off-duty or sleeping on the job, it is easy to cause a safety accident, so it is necessary to maintain a long-term high-level working state.

[0032] The passage module is arranged in the man-machine intersection passage area 10, which can be any position in the factory area, the working position where the on-site personnel 2 pass through, and the on-site personnel 2 here can be any form of staff in the field, who need to move in the field and pass through this man-machine intersection passage area 10. A detection module is arranged in the man-machine intersection passage area 10, and the detection module is used to detect the passing information of the on-site personnel 2.

[0033] Preferably, the detection module is a grating or photoelectric device set at the intersection of pedestrians and vehicles.

[0034] The warning module is used to remind the staff 1 to keep working or remind the staff 2 whether they can pass through the human-machine crossing area 10. There are many ways of warning, such as through sound, photoelectric, image, light, etc., which are not limited here.

[0035] Specifically, the safety protection system provided in the present application is mainly aimed at two situations: intelligent job inspection and intelligent personnel passage. In terms of a specific implementation method, when the industrial camera 3 takes a full-scale real-time image of the job personnel 1 and transmits it to the host computer 5, the host computer 5 can judge the on-the-job status of the personnel based on the image (off-the-job, normally on the job, sleeping on the job, tired, playing). According to the on-the-job status of the personnel, the host computer 5 can control the operation of the warning module through a controller connected to its signal, and remind the job personnel 1 to maintain a working state through the warning module, thereby ensuring the reliable and safe operation of the operating equipment 9.

[0036] Optionally, the industrial camera 3 can also determine the on-the-job status of personnel based on video dynamics combined with images.

[0037] When the transport trolley 6 is transporting and transferring goods within the factory, Figure 1 The left and right sides of the transport trolley 6 are both shelves, and the transport trolley 6 moves to transfer the goods on the shelves. The route information of the transport trolley 6 is transmitted to the host computer 5, and the detection module transmits the passing information of the personnel 2 in the field to the host computer 5. The host computer 5 makes a judgment based on the trolley route information and the passing information of the personnel. If the personnel enters the man-machine cross-passing area 10 and the transport trolley 6 is not operating in this area, the personnel can pass safely at this time; if the transport trolley 6 is already operating in the man-machine cross-passing area 10, the host computer 5 controls the warning module to operate through the controller to warn the personnel 2 in the field. At this time, the personnel cannot pass, ensuring the intelligent and safe passage of the personnel.

[0038] The above-mentioned transport vehicle 6 is preferably an automatic navigation vehicle, which can travel along a specified guidance route.

[0039] Optionally, the upper computer 5 can also judge the number of on-duty personnel based on the image, and judge whether there is any absenteeism, multiple people on duty, or the possibility of idle chatting by judging whether the number of on-duty personnel is abnormal, or judge whether the number of on-duty personnel is abnormal to ensure that the working status of the post personnel 1 is maintained and the reliable and safe operation of the operating equipment 9 is ensured.

[0040] Optionally, the upper computer 5 may pre-store position information outside the man-machine intersection area 10 and communicate with the transport vehicle 6. If the transport vehicle 6 runs to any position point within the position information, the transport vehicle 6 continues to move, and there is a possibility that the route of the on-site personnel 2 who are in the man-machine intersection area 10 may overlap, causing a safety accident. At this time, the transport vehicle 6 needs to be controlled to stop operating.

[0041] The above-mentioned safety protection system can ensure the safety of equipment and personnel regardless of day shift or night shift, leaving no blind spots. As long as personnel are within the operating range of the equipment, it will continue to issue alarms to avoid operating errors that may lead to safety accidents, and automatically monitor personnel and perform safety protection in real time.

[0042] It should be noted that the operation areas of the inspection module and the passage module are only for illustration, and the operation areas can be increased according to the actual needs of the customer, and can be flexibly set. According to actual needs, the operation conditions of the inspection module and the passage module can also be fed back to the host computer 5 in the form of a safety report so that the customer can know.

[0043] The above-mentioned safety protection system includes an inspection module, a passage module, a warning module, and a host computer 5; wherein the inspection module includes an industrial camera 3, which is used to comprehensively collect images of the personnel 1 who supervises the operation of the operating equipment to determine their on-the-job behavior. The industrial camera 3 collects comprehensive images of the personnel 1 and sends them to the host computer 5 for processing. The host computer 5 can analyze and process the collected images to determine whether the personnel are in a normal working state. If there is an abnormality, the warning module is used to remind the personnel to maintain the working state, thereby ensuring reliable supervision of the operating equipment and ensuring the safe and reliable operation of the operating equipment; a detection module is provided in the passage module, and the detection module is used to detect the passing information of the personnel 2 in the field. The passing information of the personnel 2 in the field and the passing information of the transport trolley 6 in the field are uploaded to the host computer 5. The host computer 5 determines whether the personnel 2 in the field can pass according to the passing information of the two, and controls the warning module to operate through the controller to issue a passing warning to ensure the safety of the personnel passing through the factory and the safety of the trolley transportation. Through the above-mentioned safety protection system, real-time and effective all-round monitoring and protection can be carried out to avoid human operating errors, ensure the safe operation of equipment in the factory, and ensure the personal safety of personnel.

[0044] On the basis of the above embodiment, the warning module includes a first sound and light module 4 and a second sound and light module 8. When the on-the-job behavior of the post personnel 1 is abnormal, the first sound and light module 4 can give a voice reminder and a light warning;

[0045] When the person 2 in the venue needs to pass through the human-machine intersection passage area 10, the second sound and light module 8 can give a voice reminder and project a passable mark through the projection module 7 connected thereto to remind the person 2 in the venue whether he or she can pass through the human-machine intersection passage area 10.

[0046] Please refer to Figure 1 The warning module includes a first sound and light module 4 and a second sound and light module 8, both of which include at least sound reminder and light image reminder functions. The sound reminder can be through a speaker, sound, ringtone, etc., and the light image can be through a picture, indicator light, etc.

[0047] Specifically, when the host computer 5 determines that the on-the-job behavior of the post personnel 1 is abnormal based on the image, the first sound and light module 4 can give a voice reminder and a light warning to remind the post personnel 1 to quickly resume work.

[0048] When the host computer 5 determines that a person can pass through according to the route of the trolley and the information of the person 2 in the venue, the controller can control the second sound and light module 8 to broadcast, and project a passable mark through the projection module 7 to remind the person that they can pass smoothly; when the host computer 5 determines that a person cannot pass through according to the route of the trolley and the information of the person 2 in the venue, the controller can control the second sound and light module 8 to broadcast, and project an impassable mark through the projection module 7 to remind the person that they cannot pass at this time.

[0049] The above-mentioned passable and impassable signs can be a combination of a crosswalk and a prohibited crossing picture, a combination of a green passable picture and a red prohibited crossing picture, or other symbolic markings, and no excessive restrictions are imposed here.

[0050] Optionally, there may be one or more projection modules 7 .

[0051] On the basis of any of the above embodiments, the host computer 5 is signal-connected with a notification module, and the notification module can report the abnormal behavior of the post personnel 1 on the job to the management personnel.

[0052] The notification module can be a module that connects the host computer 5 and the human-machine interface. For example, the notification module can send text messages, WeChat, phone calls, emails, phone calls, etc. to the management personnel. If the post personnel 1 still cannot maintain the working state after multiple reminders from the first sound and light module 4, such as being in a sleeping state or playing with a mobile phone or chatting state, the management personnel can be informed in time to understand their dynamics, or it can be convenient for the management personnel to respond in time, such as replacing the post personnel or taking emergency measures to stop the equipment in time, so as to avoid safety accidents caused by problems with the on-the-job personnel.

[0053] Based on any of the above embodiments, an edge intelligent server is provided in the industrial camera 3 for setting a full-range monitoring area. When the post personnel 1 is not in the monitoring area or the post personnel 1 is sleeping on the job, the host computer 5 can control the operating equipment 9 to shut down through the controller.

[0054] The industrial camera 3 is equipped with an edge intelligent server, which can define the monitoring area by itself, conduct AI fusion inspection in the monitoring area, and use the camera's face recognition and behavior recognition technology to analyze the behavior of the post personnel 1: leaving the post + sleeping on the post + playing with mobile phones + abnormal number of people + personnel retention. When any of the above abnormal behaviors occurs, it can be intelligently broadcast through the first sound and light module 4, and a corresponding abnormal record can be formed in the host computer 5; if there is a phenomenon of sleeping on the post, the operating equipment 9 can be automatically controlled to shut down through the controller after the reminder is invalid, and the management personnel will be informed in time through the notification module to ensure the safety of personnel and the safe and reliable operation of equipment.

[0055] On the basis of any of the above embodiments, an analysis module is provided in the host computer 5, and the analysis module can recognize the face of the post personnel 1 to determine whether he is tired or recognize the behavior of the post personnel 1 to determine whether he is in a working state.

[0056] In this embodiment, the analysis module can recognize the face of the staff member 1, specifically, judging the staff member's on-the-job status through the staff member's eye state, facial expression, etc., to see whether the staff member is sleeping on the job or is fatigued.

[0057] The analysis module can also identify the behavior of personnel 1 to determine whether there is an abnormal number of people, playing, etc., so as to realize real-time intelligent monitoring of whether there are people inside the equipment.

[0058] Based on any of the above embodiments, at least one group of projection modules 7 is arranged at the edge of the human-machine intersection area 10. When the personnel 2 in the venue passes through the human-machine intersection area 10, the transport cart 6 stops at the edge of the human-machine intersection area 10 or moves away from the human-machine intersection area 10.

[0059] Please refer to Figure 1 At least one group of projection modules 7 is arranged at the edge of the human-machine cross-traffic area 10. The specific limitation of this edge can be flexibly designed in combination with the actual operation situation and is not limited here.

[0060] When a person 2 in the venue passes through the human-machine intersection area 10, the transport cart 6 stops at the edge of the human-machine intersection area 10 and no longer moves or moves directly away from the human-machine intersection area 10 to ensure that the person will not collide with the cart when passing through and no safety accidents will occur.

[0061] Next, we will introduce the control method of the above safety protection system. Please refer to Figure 2 , Figure 3 , Figure 4 , the control method comprises:
