[0026] The present application provides a monitoring system. The monitoring system of the present application is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0027] Figure 1 The structure block diagram of an embodiment of the monitoring system 10 of the present application is shown. The monitoring system 10 is used to monitor the working area. The working area includes working equipment. The working equipment can be operated by personnel. When a person enters the working area illegally, a safety accident may occur.

[0028] like Figure 1 As shown, the monitoring system 10 includes: an image recognition device 11 , a main control device 12 and an alarm device 13 .

[0029] The image recognition device 11 is used to recognize the image of the working area and obtain a recognition result. The image recognition device 11 is used to monitor the image of the working area in real time, recognize the image, and obtain a recognition result. The recognition result can reflect the dynamic changes of the working area. When a person enters the working area, the recognition result can show that a person has entered the working area. The image recognition device 11 includes a camera.

[0030] In some embodiments, the image recognition device 11 includes a low light sensitive element and / or a backlight compensation element. In this way, the image recognition device 11 can adapt to dim light and backlight environments. Even when the working area is poorly illuminated, the image of the working area can be accurately captured.

[0031] In some embodiments, the image recognition device 11 can upload the collected personnel images (such as human face images) to the memory for storage. By recording and analyzing the data stored in the memory, relevant data of personnel intrusion can be obtained, which is convenient for personnel management.

[0032] In some embodiments, the image recognition device 11 is disposed opposite to the working area. In this way, the image recognition device 11 can comprehensively monitor the working area and collect images of the working area. The working area includes the hoist working area.

[0033] Figure 2 Shown is a schematic diagram of an embodiment of the monitoring system 10 of the present application and an applied working area 20 .

[0034] In some embodiments, the operation area 20 includes a pulverizer operation area, the pulverizer operation area includes a conveyor belt 21, and the image recognition device 11 is disposed in front of and / or behind the conveyor belt 21. In this way, during the conveying process of the conveyor belt 21, the image recognition device 11 can realize full process monitoring and collect images of the pulverizer operation at various times.

[0035] In some embodiments, the operation area includes the elevator operation area, and the image recognition device 11 is arranged at the entrance of the elevator operation area and is higher than the top of the elevator in the vertical direction. In the elevator operation area, the operator and the product may be located in the same direction on the roller line, and the product may block the operator's line of sight. The image recognition device 11 is arranged at the entrance of the elevator operation area and is higher than the top of the elevator in the vertical direction, so that the image recognition device 11 can collect images of the entire elevator operation area, and the image collection area of ​​the image recognition device 11 covers the roller line.

[0036] The main control device 12 is electrically connected to the image recognition device 11 and the alarm device 13 . The main control device 12 is used to receive the recognition result sent by the image recognition device 11 , and control the alarm device 13 to work according to the recognition result.

[0037] The alarm device 13 can issue an alarm reminder under the control signal of the main control device 12. The alarm device 13 includes a speaker, a flashing light, etc. The alarm reminder can be an acoustic signal or a light signal. In some embodiments, the alarm device 13 includes a sound bar. The sound bar can emit a high-decibel sound. In the noisy working area, the alarm device 13 can still issue an effective alarm signal to better protect the safety of personnel.

[0038] In some embodiments, the monitoring system 10 includes a power supply. The image recognition device 11 is connected to the power supply through a power line, and is connected to the main control device 12 through a signal line, and the power line and the signal line are independently arranged. The power line can be arranged in a strong current slot, and the signal line can be arranged in a weak current slot. There is a certain distance between the power line and the signal line. The power line and the signal line are arranged separately, which can prevent signal interference between the power line and the signal line, so that the recognition result of the image recognition device 11 can be transmitted to the main control device 12 more stably.

[0039] The main control device 12 is used to determine whether a person has entered the intrusion line of the operation area according to the recognition result, and control the alarm device 13 to alarm when a person has entered the intrusion line of the operation area.

[0040] The intrusion line is pre-set. The intrusion line is stored in the main control device 12. In the working area, the intrusion line is pre-delineated. The intrusion line can be delineated according to the distribution of the working equipment in the working area. For example, the intrusion line is delineated within the safety warning line of the working equipment. In the working area, multiple intrusion lines can be delineated. The intrusion line can be a straight line or a curve to better adapt to the equipment distribution in the working area. When a person enters the intrusion line, the image recognition device 11 recognizes that a human body has entered the intrusion line. The main control device 12 determines that a person has entered the intrusion line based on the recognition result of the image recognition device 11, and sends a control signal to the alarm device 13 to control the alarm device 13 to alarm. In some embodiments, the main control device 12 determines that part of the human body has entered the intrusion line based on the recognition result, that is, controls the alarm device 13 to alarm. In other embodiments, the main control device 12 determines that a complete human body has entered the intrusion line based on the recognition result, that is, controls the alarm device 13 to alarm. By setting the intrusion line, the monitoring system can flexibly monitor the working area.

[0041] In some embodiments, the image of the working area is recognized by the image recognition device 11, and the situation of the working area can be monitored in real time. The main control device 12 determines whether there is a person entering the intrusion line of the working area based on the recognition result, and controls the alarm device 13 to alarm when a person enters the intrusion line. In this way, when a person invades a specific location of the working area, an alarm can be issued in time to protect the safety of the personnel.

[0042] In some embodiments, the main control device 12 is also used to: determine whether there is a person entering the intrusion line of the working area based on the recognition result, and control the alarm device 13 to issue multiple alarms when a person enters the intrusion line of the working area.

[0043] In some embodiments, the main control device 12 is also used to: determine whether there is a person entering the intrusion line of the working area according to the set direction based on the recognition result, and control the alarm device 13 to sound an alarm when a person enters the intrusion line of the working area according to the set direction.

[0044] In addition to demarcating the intrusion line, you can also set the set direction of human intrusion. The set direction can be set to the direction toward the operating equipment. When a person enters the intrusion line in the direction close to the operating equipment, the monitoring system will issue an alarm, and when the person does not follow the intrusion direction, such as away from the operating equipment, the monitoring system will not issue an alarm. In this way, the monitoring system can monitor the operating area more intelligently and reduce false alarms.

[0045] In some embodiments, the main control device 12 is also used to: determine whether a person has entered the working area according to the recognition result, and control the alarm device 13 to alarm when a person enters the working area. In this way, when a person just enters the working area, an alarm can be issued in time to protect the safety of the person.

[0046] Figure 3 Shown is a schematic diagram of another embodiment of a work area 20 to which the monitoring system 10 of the present application is applied.

[0047] In some embodiments, the working area 20 includes an alarm area 22 and a non-alarm area 23, and the main control device 12 is also used to: determine whether a person enters the alarm area 22 based on the recognition result, and control the alarm device 13 to alarm when a person enters the alarm area 22.

[0048] The working area 20 is divided into an alarm area 22 and a non-alarm area 23. The division can be based on safety risk assessment, work process requirements or specific management requirements. The alarm area 22 refers to those areas where an alarm needs to be triggered immediately when a person enters due to potential dangers, sensitive operations or special attention. In contrast, the non-alarm area 23 refers to those relatively safe areas that do not require special monitoring or alarms. For example, the working equipment and its surrounding areas are used as the alarm area 22, while other areas are used as the non-alarm area 23. The main control device 12 can accurately match the recognition results with the map or layout of the working area through the built-in precise geo-positioning algorithm, area division logic or image recognition algorithm, so as to determine whether the person is located in the alarm area 22. In this way, an alarm will only be issued when a person enters the alarm area 22, thereby improving the accuracy of the alarm and reducing false alarms.

[0049] In some embodiments, the operation area also includes a warning area; the main control device 12 is also used to: determine whether a person has entered the warning area according to the recognition result, and control the alarm device 13 to warn when a person enters the warning area. The warning area can be an area with less impact on the safety of personnel. The alarm information and warning information issued by the alarm device 13 are different. When a person enters the warning area, the person can be reminded only by a light signal or a sound signal, without triggering measures such as stopping the operation equipment.

[0050] In some embodiments, the main control device 12 is further used to: determine the proportion of personnel occupying the working area according to the recognition result, and adjust the sensitivity of the image recognition device 11 according to the proportion.

[0051] The sensitivity of the image recognition device 11 is adjustable. When the proportion of intruders in the working area is large, the sensitivity of recognition can be increased to more accurately capture and identify the intruders. When the proportion of intruders in the working area is small, the sensitivity of recognition can be reduced to reduce false alarms and unnecessary resource consumption. According to the recognition results, the sensitivity of the image recognition device 11 can be dynamically adjusted to make it more flexible to adapt to the situation of the working area and better monitor.

[0052] In some embodiments, the operating equipment is electrically connected to the main control device 12; the main control device 12 is used to control the operating equipment to shut down when a person enters the intrusion line of the operating area.

[0053] When a person enters the intrusion line of the operation area, in addition to controlling the alarm device 13 to sound an alarm, the operation equipment is controlled to shut down. The shutdown operation can quickly cut off the power source of the operation equipment or stop its operation, thereby avoiding possible collisions, squeezing or other safety accidents, and preventing the operation equipment from accidentally injuring the intruder, thereby improving the safety of the personnel. In some embodiments, the operation equipment is controlled by a PLC controller, which is electrically connected to the main control device 12, receives a shutdown command sent by the main control device 12, and controls the operation equipment to shut down.

[0054] In some embodiments, the main control device 12 is used to control the reset of the operating equipment when the intrusion line of a person leaving the operating area reaches a set time. When the person leaves the operating area, the main control device 12 will not immediately control the reset of the operating equipment, but will automatically delay the set time and then control the reset of the operating equipment, which can improve safety and prevent the operator from accidentally eliminating the alarm. In some embodiments, the set time is 5S, which not only protects the safety of personnel, but also avoids the impact of long-term shutdown of the operating equipment on production.

[0055] In some embodiments, the monitoring system 10 also includes a display device electrically connected to the main control device 12, and the display device is used to receive human operation and generate an electrical signal indicating alarm confirmation; the main control device 12 is used to: control the reset of the operating equipment according to the electrical signal of the display device.

[0056] The display device may be a touch screen, an LCD display, an LED indicator panel, or other device capable of displaying information and receiving user input. When the monitoring system 10 issues an alarm, the operator may confirm the alarm through a button on the display device, a touch screen, or other input methods, and feed back the confirmation signal to the main control device 12.

[0057] After the operating equipment is controlled to shut down, in order to prevent the equipment reset from causing harm to personnel, personnel are required to operate the display device so that the display device generates an electrical signal indicating that the personnel has confirmed the alarm. After receiving the electrical signal, the main control device 12 controls the operating equipment to reset. The reset operation means restoring the operating equipment from a shutdown state to a previous operating state, or at least a safe and operable standby state. In this way, after safety is confirmed, production or processing operations can continue. Through the interaction between the display device and the main control device 12, not only the flexibility and user-friendliness of the monitoring system 10 are improved, but also it is ensured that the operating equipment can be safely resumed at the appropriate time. In a production environment that requires rapid response and precise control, downtime can be reduced and production efficiency can be improved while maintaining a high degree of safety.

[0058] In addition, the display device allows operators to record, analyze and subsequently process alarm events, thereby continuously improving safety management and work processes. When an alarm is issued, the alarm information is displayed on the display device in the form of text or pictures; when the alarm is eliminated, it is also displayed on the display device in the form of text or pictures. Through the user interface on the display device, operators can view information such as alarm history, operating equipment status, and personnel activity records to better understand and solve potential safety problems.

[0059] The present application also provides a monitoring management system, including a monitoring management page, which is used to receive at least one of the intrusion line, alarm area, and warning area set by the user, and send the information set by the user to the main control device 12. The main control device 12 monitors the operation area according to the information set by the user.

[0060] The present application also provides a monitoring method for monitoring an operation area, the monitoring method comprising:

[0062] According to the recognition result, determining whether a person has entered the intrusion line of the operation area;

[0063] If a person enters the intrusion line of the operation area, the alarm device 13 is controlled to sound an alarm.

[0064] Figure 4 Shown is a structural block diagram of an embodiment of the main control device 12 of the present application.

[0065] like Figure 4 As shown, the main control device 12 includes one or more processors 31 for implementing the monitoring method as described above.
