[0044] Figure 1 The diagram illustrates a flow chart of a control method for a control system of aerial work machinery according to an embodiment of the present invention. Figure 1 As shown in the embodiment of the present invention, a control method for a control system of aerial work machinery is provided. The control system includes a wearable device for communication via wireless communication and a work platform controller. Taking the execution of the control method on the wearable device as an example, the control method may include the following steps:

[0045] Step S102: Receive a first signal triggered by a user located on the work platform, wherein the first signal includes a work platform action command.

[0046] Step S104: Convert the first signal into a wireless signal.

[0047] Step S106: Send the wireless signal to the work platform controller.

[0048] Step S108: Receive a second signal sent by the work platform controller, wherein the second signal is obtained by the work platform controller after receiving the wireless signal, and the second signal includes work platform action instructions.

[0049] Step S110: When the first signal and the second signal are consistent, control the work platform controller to execute the work platform action command corresponding to the second signal.

[0050] Wearable devices are devices that can be worn on various parts of the human body. They may include processors and wireless communication devices, and specific forms may include seat belts or watches. The work platform controller is a controller that controls the movement of the work platform; it can also be called a vehicle controller. It can be integrated with the overall controller of the aerial work platform machinery or operate independently. The work platform controller can communicate wirelessly with the wearable devices. Users can wear wearable devices and stand on the work platform of the aerial work platform to perform aerial work. For example, users can stand on the work platform to observe obstacles or work targets from the optimal vantage point to perform operations, avoiding blind spots. The first signal is a signal triggered by the user operating the wearable device, carrying instructions for the work platform's movement. The first signal may be, for example, a photoelectric signal. The work platform movement instructions are instructions related to the work platform's movements, such as the direction and / or speed of the movement. The wireless signal is a signal that can be transmitted wirelessly, and its output form may include, but is not limited to, Bluetooth, GPS, NFC, and other technologies. The second signal is a signal obtained by the work platform controller after receiving the wireless signal sent by the wearable device. For example, it can be a photoelectric signal. Understandably, the second signal may include work platform action commands. The work platform action commands corresponding to the first signal and the work platform action commands corresponding to the second signal may be the same or different.

[0051] Specifically, the wearable device can receive a first signal triggered by a user on the work platform, which includes a work platform action command. The wearable device can convert the first signal into a wireless signal, for example, according to a wireless communication protocol, and then send the wireless signal to the work platform controller. The wearable device can then receive a second signal sent by the work platform controller. The second signal is obtained by the work platform controller after receiving the wireless signal. The second signal includes a work platform action command. The wearable device can compare the first signal and the second signal. If the first signal and the second signal are consistent, that is, if the work platform action command corresponding to the first signal is the same as the work platform action command corresponding to the second signal, the wearable device can control the work platform controller to execute the work platform action command corresponding to the second signal.

[0052] The control method described above for the control system of aerial work platforms does not require the installation of sensors to detect obstacles. After observing an obstacle, the user wearing a human-machine interface can interact with the interface. The human-machine interface can wirelessly communicate with the work platform controller to coordinate operation and realize the motion control of the work platform of the aerial work platform. This solves the problem of low working efficiency of aerial work platforms due to false alarms of sensors in the prior art. It can achieve accurate control of the work platform without relying on sensors, improving the working efficiency of both users and aerial work platforms. It also reduces the risk of operators being squeezed or collided with obstacles due to blind spots of sensors. By comparing the first and second signals, it can avoid the misoperation of the operation caused by data distortion during wireless transmission, reduce the data security risks of wireless transmission, and improve the accuracy of aerial work.

[0053] In one embodiment, the control method for the control system of the aerial work machinery may further include: issuing an alarm signal when the first signal and the second signal are inconsistent.

[0054] Specifically, if the first signal and the second signal are inconsistent, that is, the operation command of the work platform corresponding to the first signal is different from the operation command of the work platform corresponding to the second signal, it indicates that there is a data security risk in the wireless data transmission process. The wearable device can issue an alarm signal, such as an audible and visual alarm, to prompt the user to stop the operation.

[0055] In one embodiment, the control method for the control system of the aerial work machinery may further include: acquiring the transmission timestamp corresponding to the wireless signal and the reception timestamp corresponding to the second signal; and issuing an alarm signal if the interval between the reception timestamp and the transmission timestamp is longer than a first preset interval.

[0056] It can be understood that the transmission timestamp corresponding to the wireless signal is the time when the wearable device sends the wireless signal to the work platform controller, and the reception timestamp corresponding to the second signal is the time when the wearable device receives the second signal sent by the work platform controller. The first preset interval is a theoretical interval between the transmission timestamp corresponding to the wireless signal and the reception timestamp corresponding to the second signal, such as 3 seconds or 5 seconds.

[0057] Specifically, the wearable device can obtain the transmission timestamp corresponding to the wireless signal and the reception timestamp corresponding to the second signal, and compare the reception timestamp with the transmission timestamp. When the interval between the reception timestamp and the transmission timestamp is longer than a first preset interval, the wearable device can issue an alarm signal to remind the user that there is a data delay during wireless transmission.

[0058] In one embodiment, the control method for the control system of the aerial work machinery may further include: issuing an alarm signal if no second signal is received within a second preset interval.

[0059] It can be understood that the second preset interval duration is the longest interval duration between the transmission timestamp of the wireless signal and the reception timestamp of the second signal, which is predetermined or set in advance, such as 10 seconds.

[0060] Specifically, if the wearable device does not receive the second signal within a second preset interval after the transmission timestamp corresponding to the wireless signal, the wearable device can issue an alarm signal to indicate to the user that there is a problem with the wireless transmission process and that the user needs to perform maintenance.

[0061] Figure 2 The diagram schematically illustrates a control method for a control system of aerial work machinery according to another embodiment of the present invention. Figure 2 As shown in the embodiment of the present invention, a control method for a control system of aerial work machinery is provided. The control system includes a wearable device for communication via wireless communication and a work platform controller. Taking the execution of the control method on the work platform controller as an example, the control method may include:

[0062] Step S202: Receive wireless signals sent by the wearable device, wherein the wireless signals are converted by the wearable device after receiving a first signal triggered by a user located on the work platform, which includes an action command for the work platform.

[0063] Step S204: Convert the wireless signal into a second signal, wherein the second signal includes operation commands for the work platform.

[0064] Step S206: Send the second signal to the wearable device.

[0065] Step S208: Receive and execute the control command sent by the wearable device to execute the work platform action command corresponding to the second signal, wherein the control command is issued by the wearable device when it determines that the first signal and the second signal are consistent.

[0066] Specifically, the work platform controller can receive wireless signals sent by the wearable device. The wireless signal is obtained by the wearable device after receiving a first signal triggered by a user on the work platform, which includes a work platform action command. The work platform controller can then convert the wireless signal into a second signal, which includes the work platform action command, and send the second signal to the wearable device. Thus, the work platform controller can receive and execute the control command sent by the wearable device to execute the work platform action command corresponding to the second signal. The control command is issued by the wearable device when it determines that the first signal and the second signal are consistent.

[0067] The control method described above for the control system of aerial work platforms does not require the installation of sensors to detect obstacles. After observing an obstacle, the user wearing a human-machine interface can interact with the interface. The human-machine interface can wirelessly communicate with the work platform controller to coordinate operation and realize the motion control of the work platform of the aerial work platform. This solves the problem of low working efficiency of aerial work platforms due to false alarms of sensors in the prior art. It can achieve accurate control of the work platform without relying on sensors, improving the working efficiency of both users and aerial work platforms. It also reduces the risk of operators being squeezed or collided with obstacles due to blind spots of sensors. By comparing the first and second signals, it can avoid the misoperation of the operation caused by data distortion during wireless transmission, reduce the data security risks of wireless transmission, and improve the accuracy of aerial work.

[0068] In one embodiment, a control method for a control system of aerial work platform machinery is provided. Taking the application of this method to the control system of the aerial work platform machinery as an example, the control system includes a wearable human body device that communicates wirelessly and a work platform controller. Specifically, the control method may include:

[0069] Step 1: The wearable device receives a first signal triggered by a user on the work platform, wherein the first signal includes an action command for the work platform.

[0070] Step 2: The wearable device converts the first signal into a wireless signal.

[0071] Step 3: The wearable device sends a wireless signal to the work platform controller.

[0072] Step 4: The work platform controller receives the wireless signal sent by the wearable device.

[0073] Step 5: The work platform controller converts the wireless signal into a second signal, wherein the second signal includes work platform action commands.

[0074] Step 6: The work platform controller sends the second signal to the wearable device.

[0075] Step 7: The wearable device receives the second signal sent by the work platform controller.

[0076] Step 8: The wearable device can compare the first signal with the second signal. If the first signal and the second signal are consistent, the wearable device controls the work platform controller to execute the work platform action command corresponding to the second signal. Specifically, the wearable device can send the work platform action command corresponding to the second signal to the work platform controller. Conversely, if the first signal and the second signal are inconsistent, the wearable device can proceed to step 10. Furthermore, the wearable device can also obtain the transmission timestamp corresponding to the wireless signal and the reception timestamp corresponding to the second signal. If the interval between the reception timestamp and the transmission timestamp is longer than a first preset interval, the wearable device can proceed to step 10. Even further, if the wearable device does not receive the second signal within the second preset interval, it can also proceed to step 10.

[0077] Step 9: The work platform controller receives and executes the control command sent by the wearable device to execute the work platform action command corresponding to the second signal.

[0078] Step 10: The wearable device emits an alarm signal. Understandably, alarm signals for different scenarios can be differentiated according to their severity. For example, in a scenario where the interval between the received timestamp and the sent timestamp is longer than a first preset interval, the alarm signal can be a light alarm signal; in a scenario where no second signal is received within a second preset interval, the alarm signal can be an audible alarm signal.

[0079] Understandably, existing technologies are prone to false alarms. When a worker extends their hand or tools out of the work bucket, sensors in current solutions (such as ultrasonic or millimeter-wave radar) often misdetect them as obstacles, triggering alarms or restricting movement and disrupting normal operations. Current sensors lack the ability to identify workers and tools, thus failing to effectively filter out non-obstacle information, resulting in false alarms. Furthermore, sensors often struggle to identify small, pointed objects; for example, they typically cannot effectively identify pointed protrusions with a cross-sectional area less than 50×50mm, posing a safety hazard. Moreover, sensors often have blind spots, also presenting safety risks.

[0080] To address the aforementioned problems, one embodiment of the present invention provides a control method for a control system of aerial work machinery. This control method allows for remote control operation of the aerial work platform via a safety belt (i.e., a wearable device). The safety belt-wearing operator can effectively avoid the safety risks of collisions and crushing during aerial work platform operations. The specific technical solution is as follows:

[0081] A safety belt based on remote control operation includes a vehicle power module 1, an action handle module 2, a handle signal wireless conversion module 3, a data wireless transmission module 4, a vehicle response feedback module 5, and a vehicle controller with a built-in data wireless receiving module 6, a controller action feedback module 7, and an operation control unit 8. The vehicle action handle module 2 outputs the vehicle action signal to the handle signal wireless conversion module 3. The wireless transmission module 4 sends the wireless signal transmitted by module 3 to the built-in data wireless receiving module 6 in the vehicle controller, and simultaneously sends it to the vehicle response feedback module 5 for storage. The data wireless receiving module 6 sends the wireless signal to the controller action feedback module 7 to execute the vehicle operation action. The controller action feedback module 7 sends a decompiled signal and sends it back to the vehicle response feedback module 5 for verification with the stored data.

[0082] The action handle module 2 contains all the on-board action control signals. Each action control signal is output as a unique electrical signal according to the wireless transmission module communication protocol. After being converted into a wireless operation command by the conversion module 3, it is transmitted to the on-board controller data wireless receiving module 6. The data is input into the on-board controller and shared with the operating system - wireless operation control unit 7 to realize the control of the on-board operation actions.

[0083] The function of the wireless signal conversion module 3 is to convert the electrical signals of the operation commands of the action controller module 2 into wireless transmission signals according to the wireless communication protocol. The output form can be Bluetooth, GPS, NFC and other technologies.

[0084] The controller's built-in wireless data receiver module 6 receives wireless signals transmitted by the wireless data transmission module 4, converts them into operating command electrical signals, and outputs them to the controller's action feedback module 7.

[0085] The onboard response feedback module 5 is used to store the data transmitted by the wireless transmission module 4, record the data storage time, and compare and verify it with the data returned by the controller action feedback module 7 to ensure the high reliability of wireless transmission. At the same time, it compares the data storage time of the transmission module 4 and the data feedback time of the controller action feedback module 7 to ensure the real-time performance and low latency of wireless data transmission.

[0086] The working principle of the safety belt for remotely operated aerial work platforms can be summarized as follows:

[0087] Step 1: The operator wears a safety belt with remote control operation function. The remote control operation function module contains the following functional sub-modules: vehicle power module 1, action handle module 2, handle signal wireless conversion module 3, data wireless transmission module 4, and vehicle response feedback module 5.

[0088] Step 2: Install a controller with remote control response function on the vehicle control panel. The remote control response function module contains the following functional sub-modules: wireless data receiving module 6, controller action feedback module 7, and operation control unit 8.

[0089] Step 3: The safety belt remote control function and the controller remote control response function are connected wirelessly to control the working actions of the aerial work platform. The control logic can be as follows: Figure 3 As shown.

[0090] Specifically, the safety belt in this embodiment of the invention includes the following functional units: an action handle module 2, a handle signal wireless conversion module 3, a data wireless transmission module 4, a vehicle response feedback module 5, a data wireless receiving module 6, a controller action feedback module 7, and an operation control unit 8. After the operator is equipped with the safety belt of this invention, they can operate the aerial work platform from the optimal viewing position on the platform. The remote control wireless transmission scheme provided in this embodiment of the invention combines multiple wireless transmission methods such as Bluetooth, NFC, mobile network, and infrared to avoid data transmission delays or loss caused by environmental factors such as building shielding, magnetic field interference, light reflection, and dust. In addition, for the remote control wireless transmission scheme, a response feedback module 5 and a controller action feedback module 7 are added to the wireless transmission path to ensure high reliability and low latency of wireless transmission.

[0091] Optionally, the remote control module can be made into a separate accessory device that moves with the operator and can be worn on the hand, waist, or other convenient body parts. Optionally, the wireless transmission method can be diversified, employing a combination of Bluetooth, NFC, mobile network, infrared, and other wireless transmission methods to ensure highly reliable and latency-free wireless data transmission.

[0092] In summary, this invention transfers the aerial work platform's onboard operation function to the safety belt, which then remotely controls the platform's actions. Because the operator can operate from the optimal vantage point near obstacles or the target, it avoids the safety risks of collisions and crushing caused by blind spots, limited detection range, and deficiencies in recognizing sharp, protruding obstacles. It also avoids the inconvenience of alarms or movement restrictions caused by the ultrasonic anti-collision control system's lack of ability to identify personnel and tools. To ensure reliable real-time transmission of operating commands to the controller and prevent data delays and distortions during wireless transmission that could lead to erroneous operations, a verification unit consisting of the controller action feedback module 7 and the onboard response feedback module 5 effectively avoids the aforementioned safety hazards associated with wireless data transmission. This invention requires no high-precision sensors, control units, or other technical algorithm models, resulting in low cost, high reliability, and strong market applicability.

[0093] This invention also provides a processor configured to execute a control method for a control system of aerial work machinery according to any of the above embodiments.

[0094] like Figure 4 As shown, this embodiment of the invention also provides a wearable human body device 400, comprising:

[0095] The first signal receiving module 410 is used to receive a first signal triggered by a user located on the work platform, wherein the first signal includes an action command of the work platform.

[0096] The first signal conversion module 420 is used to convert the first signal into a wireless signal.

[0097] The wireless signal transmission module 430 is used to send wireless signals to the work platform controller.

[0098] The second signal receiving module 440 is used to receive a second signal sent by the work platform controller. The second signal is obtained by the work platform controller after receiving the wireless signal and includes work platform action instructions.

[0099] The motion control module 450 is used to control the work platform controller to execute the work platform motion command corresponding to the second signal when the first signal and the second signal are consistent.

[0100] The aforementioned wearable device 400 can wirelessly communicate with the work platform controller to coordinate operation, thereby realizing motion control of the work platform of the aerial work machinery. This solves the problem of low working efficiency of aerial work machinery due to sensor false alarms in the prior art. It can achieve accurate control of the work platform without relying on sensors, improving the working efficiency of users and aerial work machinery. It also reduces the risk of operators being squeezed or collided with obstacles due to blind spots in the field of vision of sensors. By comparing the first signal and the second signal, it can avoid the misoperation of work actions caused by data distortion during wireless transmission, reduce the data security risks of wireless transmission, and improve the accuracy of aerial work.

[0101] In one embodiment, the wearable device 400 further includes an alarm module for issuing an alarm signal when the first signal and the second signal are inconsistent.

[0102] In one embodiment, the wearable device 400 further includes an alarm module for acquiring the transmission timestamp corresponding to the wireless signal and the reception timestamp corresponding to the second signal; and issuing an alarm signal when the interval between the reception timestamp and the transmission timestamp is longer than a first preset interval.

[0103] In one embodiment, the wearable device 400 further includes an alarm module for issuing an alarm signal if no second signal is received within a second preset interval.

[0104] like Figure 5 As shown, this embodiment of the invention also provides a work platform controller 500, including:

[0105] The wireless signal receiving module 510 is used to receive wireless signals sent by the wearable device, wherein the wireless signal is converted by the wearable device after receiving a first signal triggered by a user located on the work platform, which includes an action command of the work platform.

[0106] The wireless signal conversion module 520 is used to convert the wireless signal into a second signal, wherein the second signal includes the operation command of the work platform.

[0107] The second signal transmitting module 530 is used to transmit the second signal to the wearable device.

[0108] The action execution module 540 is used to receive and execute control commands sent by the wearable device to execute the work platform action command corresponding to the second signal. The control commands are issued by the wearable device when it determines that the first signal and the second signal are consistent.

[0109] The aforementioned work platform controller 500 can wirelessly communicate with wearable devices to coordinate operation, enabling motion control of the work platform of aerial work machinery. This solves the problem of low work efficiency of aerial work machinery due to sensor false alarms in the prior art. It can achieve accurate control of the work platform without relying on sensors, improving the work efficiency of users and aerial work machinery. It also reduces the risk of operators being squeezed or collided with obstacles due to blind spots in the sensor's field of vision. By comparing the first and second signals, it can avoid data distortion during wireless transmission that could cause erroneous operation, reducing data security risks in wireless transmission and improving the accuracy of aerial work.
