[0033] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0035] The following is a detailed description of the professional terms involved in the embodiments of the present application:

[0036] Infrared sensing device is an electronic device that uses infrared rays to detect the existence of objects. Its main principle is to use the absorption and reflection of infrared rays by objects to determine the existence and distance of objects. Infrared sensors are generally composed of two parts: an infrared transmitter and a receiver. The transmitter will emit infrared signals to the detection area, and the receiver will receive infrared signals reflected by the object. When an object enters the detection area, part of the infrared rays will be absorbed or reflected by the object, causing the intensity of the infrared signal received by the receiver to change. According to the change in the intensity of the infrared signal received by the receiver, through the calculation and processing of the internal circuit, it is possible to determine whether the object exists, the distance, the direction of movement and other information. Infrared sensors are widely used in automatic control, security, automatic lighting control, human body sensing doors and other fields.

[0037] Electronic fence, camera-based electronic fence is a new type of electronic fence technology, which uses high-definition cameras for monitoring and protection. This electronic fence can divide the monitoring range of the camera into multiple areas. When a person or object enters a certain area, the camera will automatically trigger actions such as taking pictures and recording videos, and analyze and process through algorithms combined with artificial intelligence technology to determine whether there is an illegal intrusion. Compared with traditional electronic fences, camera-based electronic fences have the following characteristics: More comprehensive functions: In addition to the protection function of traditional fixed electronic fences, the camera's image can also be transmitted in real time to the monitoring room, mobile phones and other devices for remote real-time monitoring, achieving more comprehensive protection. Wider protection range: Areas of any shape and size can be divided and monitored, while traditional electronic fences need to rely on walls and doors and windows for protection. Higher judgment accuracy: The use of artificial intelligence technology to analyze and process the camera's image can achieve a higher judgment accuracy, greatly reducing the situation of misjudgment and missed judgment. Camera-based electronic fences are suitable for places where large areas need to be monitored and protected, such as factories, warehouses, residential areas, etc. In addition to its protective function, it can also be used for behavior monitoring and management of homes, companies and other places.

[0038] In view of the technical problems that the safety control methods in the related art have high false alarm rates and great impact on workshop production, the embodiments of the present application provide a safety control system, such as Figure 1 As shown, the system includes: a camera, an infrared sensing device, a ground pressure sensing device and a controlled device; the camera, the infrared sensing device and the ground pressure sensing device are communicatively connected with the controlled device.

[0039] Based on Figure 1 The safety control system shown, the embodiment of the present application also provides a safety control method for industrial equipment, which can ensure the personal safety of workshop personnel while reducing the probability of production line shutdown, reducing the impact on workshop generation, and greatly improving the production efficiency of the workshop.

[0040] The following is a detailed description of the safety control method for industrial equipment provided by the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0041] like Figure 2 As shown, an embodiment of the present application provides a safety control method for industrial equipment, which may include the following steps 201 and 202:

[0042] Step 201: determine whether a target object enters a protection area based on the image captured by the camera and the trigger signal of the infrared sensing device.

[0043] Exemplarily, the protection area mentioned above is a protection area of ​​a controlled device.

[0044] It should be noted that the safety control method for industrial equipment provided in the embodiment of the present application is executed by a controller with data processing capability on the controlled device, which can be a programmable logic controller (PLC) of the controlled device or a server connected to the controlled device. The controlled device can be any generating device in the workshop.

[0045] Exemplarily, the electronic fence is divided based on images captured by a camera. In the embodiment of the present application, whether a person is close to the controlled device is determined by the trigger signal sent by the electronic fence and the infrared sensing device.

[0046] Specifically, the above step 201 may include the following steps 201a1 to 201a3:

[0047] Step 201a1: upon receiving a trigger signal sent by the infrared sensing device, obtaining a real-time image captured by the camera, and identifying the real-time image to generate an identification result.

[0048] Step 201a2: Based on the recognition result of the real-time image, determine whether the target object enters the area range of the electronic fence.

[0049] Step 201a3: When the target object enters the area of ​​the electronic fence, determine that the target object enters the protection area.

[0050] It is understandable that the infrared sensing device will generate a trigger signal when an intruder crosses the warning line of the infrared sensing device, but such an alarm device often fails and may generate false alarms. For example, when a trolley or overhead crane is hoisting an object in the workshop, the infrared sensing device is easily triggered. Therefore, in the embodiment of the present application, by combining the infrared sensing device with the electronic fence to determine whether a person is close to the controlled equipment, the detection accuracy is greatly improved. Since false alarms are reduced, the impact on workshop production can also be reduced to a certain extent.

[0051] For example, for the solution of performing image recognition and judging whether the target object has entered the protection area through the PLC of the controlled device, since the computing power of the PLC is generally low, the trigger signal of the infrared sensor device can be used to trigger the PLC to recognize the target in the electronic fence area to reduce the amount of data processing. That is, when the trigger signal of the infrared sensor device is received, it is further judged whether a person has entered the area of ​​the electronic fence, thereby judging whether a person has entered the protection area.

[0052] Step 202: When it is determined that the target object enters the protection area, the controlled device is safely controlled according to the control signal triggered by the ground pressure sensing device.

[0053] Wherein, the controlled equipment is: industrial equipment located in the protection area.

[0054] For example, when it is determined that the target object enters the protection area, it can be determined based on the bottom surface pressure sensor set in the protection area whether the behavior of the target object will pose a threat to the operation of the target object itself and the controlled device.

[0055] Specifically, the above step 202 may include the following steps 202a, 202b and 202c:

[0056] Step 202a: Acquire a first pressure sensing signal collected by the ground pressure sensing device, and generate a first pressure variation law of the target object according to the first pressure sensing signal.

[0057] Step 202b: when the distance between the target object and the controlled device is less than a preset distance threshold, obtain a second pressure sensing signal collected by the ground pressure sensing device.

[0058] Step 202c: judge the behavior of the target object based on the second pressure sensing signal and the first pressure change rule, generate a behavior judgment result, and perform safety control on the controlled device according to the behavior judgment result.

[0059] The first pressure sensing signal is: a pressure sensing signal collected by the ground pressure sensing device before the target object approaches the controlled device, and the collection is stopped when the distance between the target object and the controlled device is less than the preset distance threshold.

[0060] Exemplarily, when the target object enters the protection area and moves around, the ground pressure sensing device can report in real time the pressure value of the target object when walking or standing still, that is, the above-mentioned first pressure sensing signal. Based on the first pressure sensing signal reported by the ground pressure sensing device, the pressure change law of the target object when walking normally or standing still can be determined, that is, the above-mentioned first pressure change law. When the target object is close to the controlled device (based on the target object being able to operate the controlled device or being able to touch the controlled device), the real-time pressure value of the target object can be further collected, that is, the above-mentioned second pressure sensing signal, and the pressure change law of the target object when it is close to the controlled device can be generated based on the pressure sensing signal, that is, the above-mentioned second pressure change law.

[0061] For example, after obtaining the first pressure variation law and the second pressure variation law, based on the comparison results of the two pressure variation laws, it can be determined whether the behavior of the target object will pose a threat to its personal safety or the normal operation of the controlled device.

[0062] It should be noted that if the judgment result indicates that the target object will not threaten the normal operation of the controlled device, and the operation of the controlled device will not threaten the personal safety of the target object, the target object can be reminded to leave the protection area as soon as possible. At the same time, on this basis, if the target object stays in the protection area for longer than the preset warning time, an alarm will be issued and the relevant management personnel will be notified to handle it.

[0063] Optionally, in the embodiment of the present application, the step of judging the behavior of the target object based on the second pressure sensing signal and the first pressure change rule and generating a behavior judgment result in the above step 202c may further include the following steps 202c11 and 202c12:

[0064] Step 202c11: Generate a second pressure variation law of the target object according to the second pressure sensing signal, and compare the first pressure variation law with the second pressure variation law.

[0065] Step 202c12: when the first pressure variation pattern does not match the second pressure variation pattern, determining that the behavior judgment result of the target object is a first operation behavior.

[0066] For example, in the case where the controlled equipment is a production equipment that requires personnel to expend a certain amount of effort to operate, when the target object operates the controlled equipment, the pressure value on the ground will change, and the change is different from the change pattern when the target object walks normally. Based on this, the comparison result of the second pressure change pattern and the first pressure change pattern can be used to determine whether the behavior of the target object is the first operation behavior.

[0067] Further, when it is determined that the behavior of the target object is the first operation behavior, the controlled device may be controlled to take corresponding safety measures.

[0068] Specifically, after the above step 202c12, the above step 202c may further include the following step 202c13:

[0069] Step 202c13: When the behavior judgment result indicates that the target object is the first operation behavior, control the alarm device to issue an alarm message and control the controlled device to shut down.

[0070] Exemplarily, when the behavior judgment result indicates that the target object is the first operation behavior, it is judged that the operation of the controlled device will pose a threat to the personal safety of the target object. At this time, it is necessary not only to control the alarm device to send out an alarm message, but also to control the controlled device to shut down to avoid the controlled device causing damage to the personal safety of the target object.

[0071] It should be noted that the control methods for the alarm device and the controlled device in the embodiments of the present application are all executed based on the control signal generated by the controller after determining the behavior of the target object.

[0072] Optionally, in the embodiment of the present application, the step of judging the behavior of the target object based on the second pressure sensing signal and the first pressure change rule and generating a behavior judgment result in the above step 202c may further include the following steps 202c21 and 202c22:

[0073] Step 202c21: Generate a second pressure variation law of the target object according to the second pressure sensing signal, and compare the first pressure variation law with the second pressure variation law.

[0074] Step 202c22: When the first pressure variation pattern matches the second pressure variation pattern, if an operation signal sent by the operating device of the controlled device is received, determine that the behavior judgment result of the target object is the second operation behavior.

[0075] For example, in the case where the controlled device is a production device that can be controlled by an operating device (e.g., a control panel), when the target object operates the controlled device through the operating device, since the operation is not allowed and authorized, the controlled device may not execute all operating signals issued by the operating device.

[0076] Further, after the above step 202c22, the above step 202c may further include the following step 202c23:

[0077] Step 202c23: When the behavior judgment result indicates that the target object is the second operation behavior, control the alarm device to issue an alarm message, and control the controlled device to enter the first controlled state.

[0078] Wherein, when the controlled device is in the first controlled state, the controlled device does not execute the operation information sent by the operating device.

[0079] Exemplarily, the first controlled state is a state in which the controlled device does not execute any operation signal sent by the operating device. In the first controlled state, all operations of the target object on the operating device will not affect the normal operation of the controlled device. In this way, it is possible to prevent irrelevant personnel from affecting the normal operation of the controlled device.

[0080] In a possible implementation, if the controlled device encounters a sudden failure and requires emergency control (eg, emergency shutdown), the target object can release the above-mentioned operation restriction through a specific gesture.

[0081] Specifically, the above step 202c may further include the following steps 202c31 and 202c32:

[0082] Step 202c31: Acquire the real-time image captured by the camera, and perform gesture recognition on the target object in the real-time image.

[0083] Step 202c32: When it is recognized that the real-time image contains a target gesture, control the controlled device to enter a second controlled state.

[0084] Wherein, when the controlled device is in the second controlled state, the controlled device executes the operation information sent by the operating device.

[0085] For example, when the controlled device encounters an emergency and needs emergency control, the target object can make a specific gesture to the camera to make the controlled device enter the second controlled state. In the second controlled state, the controlled device can respond to all control signals triggered by the target object on the operating device.

[0086] The safety control method for industrial equipment provided in the embodiment of the present application first determines whether the target object has entered the protection area based on the image captured by the camera and the trigger signal of the infrared sensing device; then, if it is determined that the target object has entered the protection area, the controlled device is safely controlled according to the control signal triggered by the ground pressure sensing device; wherein the controlled device is an industrial device located in the target area. In this way, while ensuring the personal safety of workshop personnel, it can also reduce the probability of production line shutdown and reduce the impact on workshop generation.
