Description

Technical Field

[0001] This invention relates to the field of equipment control, and more specifically to an anti-pinch system, control method, control device, and medium for aerial work equipment. Background Technology

[0002] With the rapid development of aerial work platform manufacturing technology, aerial work platforms are widely used in various work scenarios. Aerial work platforms typically include scissor lifts and boom lifts. By controlling the lifting and lowering of the aerial work platform, workers positioned on it can perform tasks at a designated height. When controlling the movement of the aerial work platform, if an obstacle is observed near the platform, the worker must stop the platform to avoid collisions or crushing accidents. Existing technology includes protective devices such as swing-arm anti-crushing devices or flexible cable-operated anti-crushing devices on the control panel of the aerial work platform.

[0003] However, protective devices such as swing-arm anti-pinch devices or flexible cable-type anti-pinch devices only trigger the braking of the aerial work platform when a worker collides and is crushed by an obstacle. This cannot prevent such collisions and crushing, resulting in low safety for the aerial work platform. Furthermore, even when the braking is triggered, the aerial work platform may still travel a certain distance, potentially causing further collision and crushing injuries to the worker. Therefore, the safety of existing aerial work platforms is relatively low. Summary of the Invention

[0006] The detection device is installed on the work platform, and each ultrasonic radar is installed on a wearable device;

[0007] A detection device is used to determine whether the operator is on the work platform;

[0008] Ultrasonic radar is used to determine the real-time distance between a worker and an obstacle when there is an obstacle in the blind spot of a worker wearing wearable devices.

[0009] The control device is configured to:

[0011] Respond to the motion commands of the work platform and control the movement of the work platform;

[0012] If any real-time distance is less than the preset safe distance, control the work platform to brake.

[0013] In conjunction with the first aspect, in the first possible implementation, the control device is further configured to:

[0014] If the detection device determines that the operator is not located on the work platform, it does not respond to the real-time distance between the operator and the obstacle determined by each ultrasonic radar.

[0015] In conjunction with the first aspect, in the second possible implementation, the aerial work platform also includes a control device, which is located on the work platform;

[0016] A control device, configured to receive the real-time distance between the worker and an obstacle determined by each ultrasonic radar when the detection device determines that the worker is located on the work platform, includes: a control device configured to:

[0017] Once the detection device determines that the operator is located on the work platform and receives the upper control mode command, it receives the real-time distance between the operator and the obstacle determined by each ultrasonic radar. The upper control command is used to request the receipt of motion commands sent by the control device.

[0018] In conjunction with the first aspect, in a third possible implementation, the wearable device includes a power supply and a communication device:

[0019] Power supply, used to power each ultrasonic radar;

[0020] A communication device used to transmit real-time distance data to a control device.

[0021] In conjunction with the first aspect, in the fourth possible implementation, the anti-pinch system of the aerial work platform also includes an alarm device;

[0022] An alarm device is used to generate an alarm message when the real-time distance is less than a preset safe distance.

[0023] In conjunction with the first aspect, in the fifth possible implementation, the detection device is an infrared sensor.

[0024] In conjunction with the first aspect, in the sixth possible implementation, the wearable device includes at least one of a safety helmet, a safety belt, and work clothes.

[0025] Secondly, this application provides a control method applied to a control device of an anti-pinch system for aerial work equipment as described in any of the first aspects, the control method comprising:

[0026] Once the detection device determines that the operator is located on the work platform, it receives the real-time distance between the operator and the obstacle determined by each ultrasonic radar.

[0027] Respond to the motion commands of the work platform and control the movement of the work platform;

[0028] If any real-time distance is less than the preset safe distance, control the work platform to brake.

When the detection device determines that the operator is on the work platform, the real-time distance between the operator and the obstacle determined by the ultrasonic radar avoids collisions and pinching caused by the operator not observing obstacles in their blind spot. When the real-time distance is less than the safety distance, the work platform is braked before a collision and pinch occurs, preventing contact between the operator and the obstacle and improving the safety of the aerial work platform.

[0049] Example 1

[0050] Please see Figure 1 , Figure 1 A schematic diagram of a first type of anti-pinch system for aerial work equipment provided in this application embodiment is shown.

[0051] In the embodiments of this application, the aerial work equipment includes a work platform 200. Figure 1 The anti-pinch system 100 for high-altitude work equipment includes a wearable device 110, a control device 120, a detection device 130, and at least one ultrasonic radar 140;

[0052] The detection device 130 is installed on the work platform 200, and each ultrasonic radar 140 is installed on the wearable device 110;

[0053] Detection device 130 is used to determine whether the operator is located on the work platform 200;

[0054] The ultrasonic radar 140 is used to determine the real-time distance between the operator and the obstacle when an obstacle appears in the blind spot of the operator wearing the wearable device 110.

[0055] Control device 120 is configured to:

[0056] When the detection device 130 determines that the operator is located on the work platform 200, it receives the real-time distance between the operator and the obstacle determined by each ultrasonic radar 140.

[0057] Responding to the motion commands of the work platform 200, control the movement of the work platform 200;

[0058] If any real-time distance is less than the preset safe distance, control the work platform 200 to brake.

[0059] The type of aerial work platform is determined based on actual needs; it can be a scissor lift platform 200 or a boom lift platform 200, and is not limited here. The number and type of ultrasonic radar 140 are also determined based on actual needs and are not limited here. Each ultrasonic radar 140 is installed on the wearable device 110 to determine the real-time distance between the worker and obstacles when obstacles appear in the blind spot of the worker wearing the wearable device 110. For ease of understanding, only one ultrasonic radar 140 is shown in the figure.

[0060] Please see Figure 2 , Figure 2 The diagram illustrates an application example of the anti-pinch system for aerial work equipment provided in this application embodiment.

[0061] A detection device 130 is installed on the work platform 200 to determine whether the operator is located on the work platform 200. When the operator is on the work platform 200 controlling the aerial work equipment, the operator's back is usually a blind spot. An ultrasonic radar 140 is installed on the wearable device 110 corresponding to the operator's back to determine the real-time distance between the operator and obstacles in the operator's blind spot.

[0062] The control device 120 is configured to receive the real-time distance between the worker and an obstacle determined by each ultrasonic radar 140 when the detection device 130 determines that the worker is located on the work platform 200. When the position of the worker on the work platform 200 changes as the work platform 200 moves, there is a possibility that the continuous movement of the work platform 200 could cause the worker to collide with or be squeezed by an obstacle in the blind spot. When the detection device 130 determines that the worker is located on the work platform 200, it receives the real-time distance between the worker and the obstacle determined by each ultrasonic radar 140, and then determines whether the movement of the work platform 200 will cause a collision or squeezing between the worker and the obstacle based on the real-time distance between the worker and the obstacle.

[0063] Control device 120 is configured to respond to motion commands from work platform 200 and control the movement of work platform 200. Workers on work platform 200 control its movement using motion commands; specifically, control device 120 responds to received motion commands and controls the movement of work platform 200. During the movement of work platform 200, control device 120 updates the received real-time distance between the worker and obstacles in real time to determine whether the real-time distance between the worker and obstacles is less than a preset safe distance.

[0064] The control device 120 is configured to brake the work platform 200 when any real-time distance is less than a preset safe distance. During the movement of the work platform 200, if it is determined that continued movement of the work platform 200 will cause the worker to collide and be crushed by an obstacle when the real-time distance is less than the safe distance, the control device 120 controls the work platform 200 to brake, so as to switch the work platform 200 from the moving state to the stopped state.

[0065] It is important to understand that due to the different locations where the ultrasonic radars 140 are positioned, the real-time distance detected by each ultrasonic radar 140 between the worker and the obstacle will vary. The control device 120 determines the minimum real-time distance for processing to avoid malfunction. Specifically, if the minimum real-time distance is less than the safe distance, that is, if any real-time distance is less than the safe distance, the work platform 200 will be braked.

[0066] When the detection device 130 determines that the worker is located on the work platform 200, the ultrasonic radar 140 determines the real-time distance between the worker and the obstacle, preventing collisions and crushing caused by the worker not observing obstacles in their blind spot. Simultaneously, since the work platform 200 continues to move a certain distance when braking, if the real-time distance is less than the safe distance, the work platform 200 is braked before a collision and crushing occurs, preventing contact between the worker and the obstacle and improving the safety of the aerial work equipment.

[0067] In embodiments of this application, the control device 120 is further configured to:

[0068] If the detection device 130 determines that the operator is not located on the work platform 200, it does not respond to the real-time distance between the operator and the obstacle determined by each ultrasonic radar 140.

[0069] When the detection device 130 determines that the operator is not located on the work platform 200, the operator's position does not change with the movement of the work platform 200, and the operator will not collide or be squeezed by the obstacle due to the movement of the work platform 200. It does not respond to the real-time distance between the operator and the obstacle determined by each ultrasonic radar 140.

[0070] If the detection device 130 determines that the operator is not located on the work platform 200, the control device 120 will not respond to receive the real-time distance. That is, the control device 120 is configured to no longer judge whether the real-time distance is less than the preset safe distance, so as to avoid the control device 120 mistakenly judging that the operator not located on the work platform 200 is too close to the obstacle, thereby avoiding the control device 120 mistakenly controlling the work platform 200 to brake and affecting the efficiency of high-altitude operations.

[0071] It should be understood that in the embodiments of this application, the control device 120 only determines whether the real-time distance is less than the preset safe distance during the movement of the work platform 200. Specifically, when the operator is performing high-altitude work on the work platform 200, the work platform 200 is usually required to be in a stopped state. The control device 120 does not receive movement commands from the work platform 200, and there is no risk of collision or squeezing between the operator and obstacles. The control device 120 does not respond to the real-time distance between the operator and obstacles determined by each ultrasonic radar 140, thus avoiding the ultrasonic radar 140 from mistakenly identifying the components of the work platform 200 as obstacles due to the operator's special standing position or body posture during high-altitude work, thereby preventing the control device 120 from mistakenly triggering the braking of the work platform 200 and affecting the high-altitude work.

[0072] In the embodiments of this application, the aerial work equipment also includes a control device, which is disposed on the work platform 200;

[0073] When the detection device 130 determines that the worker is located on the work platform 200, it receives the real-time distance between the worker and the obstacle determined by each ultrasonic radar 140, including:

[0074] When the detection device 130 determines that the operator is located on the work platform 200 and receives the upper control mode command, it receives the real-time distance between the operator and the obstacle determined by each ultrasonic radar 140. The upper control command is used to request the use of the control device to send the movement command of the work platform 200.

[0075] Typically, the work platform 200 is equipped with a control device. The type of control device is determined according to actual needs; it can be a control box, a control panel, etc., and is not limited here. When the operator on the work platform 200 needs to control the movement of the work platform 200, they use the control device to send movement commands to the control device 120.

[0076] The control device 120 typically operates in two modes: an upper control mode and a lower control mode. The upper control command requests the receipt of motion commands from the control device, i.e., it requests the control device 120 to switch to upper control mode. The lower control command requests the receipt of motion commands from the remote control device, i.e., it requests the control device 120 to switch to lower control mode. The remote control device is used to remotely control the aerial work platform equipment. The type of remote control device is determined based on actual needs and can be a remote control handle, etc., and is not limited here.

[0077] If the detection device 130 determines that the operator is located on the work platform 200 and receives an upper control mode command, then it determines that the operator needs to use the control device to control the movement of the work platform 200 and receives the real-time distance between the operator and obstacles determined by each ultrasonic radar 140 to avoid collisions. If the detection device 130 determines that the operator is located on the work platform 200 but has not received an upper control mode command, then it determines that the operator does not need to use the control device to control the movement of the work platform 200. When the operation of the work platform 200 is not controlled, the control device 120 does not respond to the real-time distance between the operator and obstacles determined by each ultrasonic radar 140; that is, the control device 120 does not determine whether the real-time distance is less than a preset safe distance.

[0078] In embodiments of this application, the wearable device 110 includes a power supply 111 and a communication device 112:

[0079] Power supply 111 is used to power each ultrasonic radar 140;

[0080] Communication device 112 is used to transmit real-time distance to control device 120.

[0081] Please see Figure 3 , Figure 3 A schematic diagram of the structure of the wearable device provided in an embodiment of this application is shown.

[0082] For ease of understanding, in the embodiments of this application, the wearable device 110 is a seat belt, and the wearable device 110 includes a power supply 111 and a communication device 112 disposed on the seat belt. It should be understood that the type of power supply 111 is selected according to actual needs and is not limited here. The power supply 111 is connected to each ultrasonic radar 140 via power supply 111 lines, and the power supply 111 and power supply 111 lines are not shown in the figures. The power supply 111 is used to supply power to each ultrasonic radar 140 to drive the ultrasonic radar 140 to determine its position.

[0083] Please see Figure 4 , Figure 4 A second structural schematic diagram of the anti-pinch system for aerial work equipment provided in this application embodiment is shown.

[0084] The type of communication device 112 is selected according to actual needs, and can be a wireless output device, etc., without limitation. Communication device 112 is connected to ultrasonic radar 140 via a transmission line, which is not shown in the figure. Communication device 112 is used to transmit the real-time distance determined by ultrasonic radar 140 to control device 120. Furthermore, control device 120 can transmit commands through communication device 112 to control the start or stop of ultrasonic radar 140.

[0085] In the embodiments of this application, the anti-pinch system 100 of the aerial work equipment also includes an alarm device;

[0086] An alarm device is used to generate an alarm message when the real-time distance is less than a preset safe distance.

[0087] The anti-pinch system 100 for aerial work platforms also includes an alarm device. The type of control device 120 is selected according to actual needs and is not limited here. The alarm device is connected to the ultrasonic radar 140. The alarm device is used to obtain the real-time distance determined by the ultrasonic radar 140 and determine whether the real-time distance is less than the preset safe distance. If the real-time distance is less than the preset safe distance, an alarm prompt message is generated.

[0088] The type of alarm notification message is selected according to actual needs, and can be audible or visual information, etc., without limitation here. For ease of understanding, in the embodiments of this application, the alarm device is a buzzer, and the alarm notification message is a buzzing sound.

[0089] In the embodiments of this application, the detection device 130 is an infrared sensor.

[0090] Please see Figure 5 , Figure 5 The diagram shows an application example of the detection device 130 provided in the embodiments of this application.

[0091] An infrared sensor is a device that uses infrared light for measurement. In the embodiments of this application, the detection device 130 is an infrared sensor. As shown in the figure, the detection device 130 is disposed on the work platform 200 to measure the distance between the worker and the work platform 200, and to determine whether the worker is located on the work platform 200 based on the distance between the worker and the work platform 200. When the worker uses the control device to control the work platform 200, the distance between the worker and the work platform 200 measured by the detection device 130 is lower, thus determining that the worker is located on the work platform. When the detection device 130 determines that the worker is located on the work platform 200 and receives the upper control mode command, the control device 120 receives the real-time distance between the worker and the obstacle determined by each ultrasonic radar 140.

[0092] In embodiments of this application, wearable device 110 includes at least one of a safety helmet, a safety belt, and work clothes.

[0093] When working at heights, workers need to wear different types of wearable equipment 110 to improve safety. Wearable equipment 110 includes at least one of a safety helmet, a safety belt, and work clothes; specifically, taking a safety belt as an example. A safety belt typically includes straps, ropes, and metal ties, and is used to prevent workers from falling while working at heights.

[0094] The number of ultrasonic radars 140 can be determined based on their detection range, and each ultrasonic radar 140 can be installed on at least one of a safety helmet, safety belt, and work clothes, ensuring that obstacles within the worker's blind spot and outside the protection range of a guardrail are within the detection range of at least one ultrasonic radar 140. When an ultrasonic radar 140 is installed on work clothes, its detection range is affected by the worker's posture. For ease of understanding, in the embodiments of this application, all ultrasonic radars 140 are installed on safety belts to avoid the detection range of the ultrasonic radars 140 being affected by the worker's posture.

[0095] This application provides an anti-pinch system 100 for aerial work platforms. The aerial work platform includes a work platform 200. The anti-pinch system 100 includes a wearable device 110, a control device 120, a detection device 130, and at least one ultrasonic radar 140. The detection device 130 is disposed on the work platform 200, and each ultrasonic radar 140 is disposed on the wearable device 110. The detection device 130 is used to determine whether the operator is located on the work platform 200. The ultrasonic radar 140 is used to determine the real-time distance between the operator and the obstacle when an obstacle appears in the blind spot of the operator wearing the wearable device 110. The control device 120 is configured to: receive the real-time distance between the operator and the obstacle determined by each ultrasonic radar 140 when the detection device 130 determines that the operator is located on the work platform 200; control the movement of the work platform 200 in response to the movement command of the work platform 200; and control the braking of the work platform 200 when any real-time distance is less than a preset safety distance. When the detection device 130 determines that the worker is located on the work platform 200, the ultrasonic radar 140 determines the real-time distance between the worker and the obstacle, preventing collisions and crushing caused by the worker not observing obstacles in their blind spot. If the real-time distance is less than the safe distance, the work platform 200 is braked before a collision and crushing occurs, preventing contact between the worker and the obstacle and improving the safety of the aerial work equipment.
