Abstract
Description
Technical Field
[0001] This invention relates to the field of remote control technology for container stacking equipment, and specifically to a remote control method and system for a stacker. Background Technology
[0002] Container stackers, characterized by their mobility, fast loading and unloading speeds, and ease of operation, have become essential loading and unloading equipment for container logistics companies. However, container stackers require highly qualified operators with a strong emphasis on safety awareness, making recruitment of operators difficult and insufficient to meet the demand for stacker operators in port operations. 5G communication technology offers advantages such as high speed, low latency, and massive connectivity, with latency as low as less than 1 millisecond. Thanks to the ultra-low latency of 5G technology, remote control technology has developed rapidly in recent years, making remote control of container stackers possible.
[0003] Currently, the methods for remotely controlling container stackers typically involve installing various sensors in the stacker, such as posture sensors and monitoring cameras. When the posture sensor detects that the stacker is tilting to the right, a control command is remotely sent to the stacker to adjust the center of gravity of the lifted container to maintain the stacker's balance. Alternatively, the working status of the stacker can be remotely controlled through the real-time monitoring images transmitted back by the monitoring camera, such as remotely controlling the stacker to perform actions like moving forward, backward, turning, and lifting containers.
[0004] Safety control for remote operation of forklifts can be divided into two types: pre-operation control and in-operation control. The existing remote control methods for forklifts mentioned above do not focus on pre-operation safety control, but only on in-operation control during the remote control process. In in-operation safety control, remote operators need to use on-site monitoring equipment to determine whether the forklift is operating in a safe working environment. This is essentially the same as the driver's on-site attention to operational safety. Furthermore, monitoring on-site remotely makes it more difficult to avoid blind spots compared to the driver being on-site. Therefore, it is difficult to ensure safe remote operation of forklifts through technical means. Thus, those skilled in the art have focused on pre-operation safety control for remote forklift operation. However, how to achieve pre-operation safety control for remote forklift operation has become a pressing technical problem to be solved in this field. Summary of the Invention
[0005] This invention aims to improve the safety of remotely controlled container stackers by enabling pre-emptive safety control. It provides a method and system for remotely controlling stackers.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A method for remotely controlling a forklift is provided, comprising the following steps:
[0008] S1, the remote server verifies the wireless connection permission of the control chip of each forklift, and after the verification is successful, establishes a wireless communication connection with each control chip through the wireless communication module.
[0009] S2, each of the control chips wirelessly transmits the operating data of the corresponding forklift to the remote server, and the remote server generates a remote control command based on the received data and sends it to the corresponding control chip;
[0010] S3, each of the control chips controls the corresponding forklift machine to perform corresponding remote control actions according to the received remote control command.
[0011] Preferably, step S1, the method for establishing a wireless communication connection between each control chip and the remote server via the wireless communication module, includes the following steps:
[0012] A1, each of the control chips generates a wireless connection request and sends it to the wireless communication module when the forklift is switched to the remote control working mode. The wireless connection request carries the unique device number of the forklift, the cockpit monitoring data, and the monitoring data and illuminance sensing data of the monitoring and illuminance sensing devices installed on the forklift at night for the designated area.
[0013] A2, the wireless communication module initiates a communication connection request to the remote server, the communication connection request carrying the unique module number of the wireless communication module itself and the wireless connection request sent by each of the control chips;
[0014] A3, the remote server parses the received communication connection request;
[0015] A4. The remote server matches the unique module number of the wireless communication module parsed in step A3 with the module numbers stored in the module number database.
[0016] If the match is successful, a wireless communication connection is established with the wireless communication module, and then proceed to step A5;
[0017] If the match fails, the communication connection request of the wireless communication module is rejected;
[0018] A5, the remote server matches the unique device number corresponding to each forklift machine parsed in step A3 with the device numbers stored in the device number database.
[0019] If the match is successful, proceed to step A6;
[0020] If the matching fails, the wireless communication module is notified to disconnect the communication connection with the corresponding control chip.
[0021] A6, the remote server determines whether the cockpit monitoring data parsed in step A3 includes facial data.
[0022] If so, the wireless communication module is notified to disconnect from the corresponding control chip and an alarm is triggered indicating that the remote control conditions have not been met.
[0023] If not, the wireless communication module is notified to maintain the communication connection with the corresponding control chip or not to respond.
[0024] Preferably, when remotely controlling the forklift at night, the wireless connection request also carries monitoring data and illuminance sensing data of the designated area from the monitoring and illuminance sensing devices installed on the forklift. At night, the method for establishing a wireless communication connection between each control chip and the remote server via the wireless communication module, based on steps A1-A6, further includes the following step:
[0025] A7, the remote server randomly selects a frame of monitoring image from the monitoring data collected by the monitoring and illuminance sensing device in step A3 and calculates the brightness to obtain the brightness value of the monitoring image.
[0026] A8, calculate the difference between the brightness value of the monitoring image calculated in step A7 and the illuminance value of the illuminance sensor data obtained in step A3;
[0027] A9, determine whether the difference between the luminance value and the illuminance value is less than a preset difference threshold.
[0028] If so, the wireless communication module is notified to maintain the communication connection with the corresponding control chip;
[0029] If not, the wireless communication module is notified to disconnect from the corresponding control chip and an alarm is triggered indicating insufficient ambient light during remote operation.
[0030] Preferably, the wireless communication module is a 5G communication module.
[0031] The present invention also provides a remote control system for a forklift, which can realize the aforementioned remote control method for a forklift. The remote control system for the forklift includes:
[0032] The remote server is used to verify the wireless connection permissions of the control chips of each forklift, and after successful verification, establishes a wireless communication connection with each control chip through the wireless communication module; the wireless communication module is used as an "intermediate bridge" to realize the wireless communication connection between the remote server and each control chip.
[0033] Each of the control chips is configured to establish a wireless communication connection with the remote server via the wireless communication module, and then wirelessly transmit the operating data of the corresponding stacker to the remote server. The remote server generates a remote control command based on the received data and sends it to the corresponding control chip. Each of the control chips controls the corresponding stacker to perform a corresponding remote control action based on the received remote control command.
[0034] Preferably, the wireless communication module includes:
[0035] The communication connection request initiation module is used to generate a communication connection request by combining the wireless connection requests sent by each of the control chips with its own unique module code and send it to the remote server. The wireless connection request carries the unique device number of the forklift, the cockpit monitoring data, and the monitoring data and illuminance sensing data of the monitoring and illuminance sensing devices installed on the forklift at night for a designated area.
[0036] The communication connection disconnection module is used to disconnect the wireless communication connection with the corresponding control chip according to the communication connection disconnection notification instruction sent by the remote server;
[0037] The remote server includes:
[0038] The data parsing module is used to parse the received communication connection request.
[0039] The first matching module, connected to the data parsing module, is used to match the unique module number of the parsed wireless communication module with the module numbers stored in the module number database.
[0040] If a match is successful, a wireless communication connection is established with the wireless communication module, and a second matching signal is generated;
[0041] If the match fails, the communication connection request of the wireless communication module is rejected;
[0042] The second matching module, connected to the data parsing module and the first matching module, is used to match, upon receiving the second matching signal, the unique device number corresponding to each forklift machine obtained from the parsing with the device numbers stored in the device number database.
[0043] If a match is successful, a third matching signal is generated;
[0044] If the matching fails, the wireless communication module is notified to disconnect the communication connection with the corresponding control chip.
[0045] The first judgment module, connected to the data parsing module and the second matching module, is used to determine, after receiving the third matching signal, whether the parsed cockpit monitoring data includes facial data.
[0046] If so, the wireless communication module is notified to disconnect from the corresponding control chip, and a first alarm signal is generated to indicate that the conditions for remote control of the corresponding forklift have not been met.
[0047] If not, the wireless communication module is notified to maintain the communication connection with the corresponding control chip or not to respond.
[0048] A brightness value calculation module, connected to the data parsing module, is used to calculate the brightness of any frame of monitoring image taken from the monitoring data collected by the monitoring and illuminance sensing devices, and obtain the brightness value of the monitoring image.
[0049] The difference calculation module is connected to the brightness value calculation module and the data parsing module, and is used to calculate the difference between the calculated brightness value and the illuminance value of the parsed illuminance sensing data.
[0050] The second judgment module, connected to the difference calculation module, is used to determine whether the difference between the luminance value and the illuminance value is less than a preset difference threshold.
[0051] If so, the wireless communication module is notified to maintain the communication connection with the corresponding control chip;
[0052] If not, the wireless communication module is notified to disconnect from the corresponding control chip and generate a second alarm signal to indicate insufficient ambient light in the remote operation environment.
[0053] This invention achieves pre-emptive safety control of remote forklift control by verifying the wireless connection permissions of the control chips of each forklift via a remote server. In verifying the wireless connection permissions of the forklifts, the invention sequentially verifies the unique module number of the wireless communication module, the existence of the unique device number corresponding to each forklift, the presence of facial data in the cab, and whether the illumination in the designated area meets the operational requirements in a nighttime working environment. This significantly reduces the safety risks of remotely operating forklifts. Attached Figure Description

[0057] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0058] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0060] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0061] The remote control method for forklifts provided in this embodiment of the invention, such as... Figure 1 As shown, it includes the following steps:
[0062] S1, the remote server verifies the wireless connection permission of the control chip of each forklift, and after the verification is successful, establishes a wireless communication connection with each control chip through the wireless communication module.
[0063] S2, each control chip wirelessly transmits the operating data of its corresponding forklift to the remote server. The remote server generates remote control commands based on the received data and sends them to the corresponding control chip.
[0064] S3, each control chip controls the corresponding forklift to perform corresponding remote control actions according to the received remote control commands.
[0065] Step S1, the method for establishing a wireless communication connection between each control chip and the remote server via the wireless communication module, specifically includes the following steps:
[0066] A1. Each control chip generates a wireless connection request and sends it to the wireless communication module when the forklift is switched to remote control mode (the forklift is equipped with a mode switch that can switch between remote control mode and on-site manual control mode). The wireless connection request carries the forklift's unique device number, the cab monitoring data, and the monitoring and illuminance sensing data of the monitoring and illuminance sensing devices installed on the forklift for the designated area at night (if it is daytime, the monitoring and illuminance sensing devices are not working, so when remotely controlling the forklift during the day, the wireless connection request does not carry the monitoring and illuminance sensing data of the monitoring and illuminance sensing devices for the designated area at night. The designated area here refers to the best field of vision area for the forklift to lift the container, such as a rectangular area of 10 square meters 5 meters in front of the forklift).
[0067] A2, the wireless communication module (preferably a 5G communication module; there are many existing 5G communication modules that can be applied to this application, so the specific brand and model of the 5G communication module used will not be specified here) initiates a communication connection request to the remote server. The communication connection request carries the unique module number of the wireless communication module itself and the wireless connection request sent by each control chip.
[0068] A3, The remote server parses the data of the received communication connection request;
[0069] A4. The remote server matches the unique module number of the wireless communication module parsed in step A3 with the module numbers stored in the module number database.
[0070] If the match is successful, a wireless communication connection is established with the wireless communication module, and then proceed to step A5;
[0071] If a match fails, the communication connection request from the wireless communication module is rejected.
[0072] A5. The remote server matches the unique device number corresponding to each forklift machine parsed in step A3 with the device numbers stored in the device number database.
[0073] If the match is successful, proceed to step A6;
[0074] If the matching fails, the wireless communication module is notified to disconnect the communication connection with the corresponding control chip.
[0075] A6. The remote server determines whether the cockpit monitoring data parsed in step A3 includes facial data (including facial data indicates that there is someone in the forklift cockpit at the current time; if the forklift is remotely controlled at this time, remote control and on-site human control may occur simultaneously, which will bring great safety hazards to the forklift operation).
[0076] If so, the wireless communication module is notified to disconnect from the corresponding control chip and an alarm is triggered indicating that the remote control conditions have not been met.
[0077] If not, the wireless communication module is notified to maintain the communication connection with the corresponding control chip or not to respond (the wireless communication module has already established a wireless communication connection with the control chip when it receives the wireless connection request sent by the control chip).
[0078] When remotely controlling a forklift at night, the wireless connection request also carries monitoring data and illuminance sensing data of the designated area from the monitoring and illuminance sensing devices installed on the forklift. In addition to steps A1-A6, the method for establishing a wireless communication connection between each control chip and the remote server via the wireless communication module at night also includes the following steps:
[0079] A7. The remote server randomly selects a frame of monitoring image from the monitoring data collected by the monitoring and illuminance sensing devices in step A3 and calculates the brightness to obtain the brightness value of the monitoring image. The brightness value calculation of the monitoring image is a conventional image brightness calculation method, so the specific calculation process is not explained.
[0080] A8. Calculate the difference between the brightness value of the monitoring image calculated in step A7 and the illuminance value of the illuminance sensor data obtained in step A3. The illuminance value is directly detected by the monitoring and illuminance sensing equipment. For example, an illuminance sensor is installed on the boom of a forklift. The illuminance sensor is aimed at the designated area to be detected. The light signal reflected from the designated area enters the illuminance sensor and is converted into an electrical signal. The illuminance sensor analyzes and calculates the illuminance value of the designated area based on the converted electrical signal. Many illuminance sensors on the market can be directly used in this application; therefore, the specific brand and model of the illuminance sensor used in this application are not specified.
[0081] A9, determine whether the difference between the luminance value and the illuminance value is less than a preset difference threshold.
[0082] If so, then instruct the wireless communication module to maintain the communication connection with the corresponding control chip;
[0083] If not, the wireless communication module is notified to disconnect from the corresponding control chip and an alarm is triggered indicating insufficient ambient light during remote operation.
[0084] This invention also provides a remote control system for a forklift, which can realize the above-mentioned remote control method for a forklift, such as... Figure 2 As shown, the system includes:
[0085] The remote server is used to verify the wireless connection permissions of the control chips of each forklift, and after successful verification, it establishes a wireless communication connection with each control chip through the wireless communication module; the wireless communication module is used as an "intermediate bridge" to realize the wireless communication connection between the remote server and each control chip.
[0086] Each control chip is used to establish a wireless communication connection with the remote server through the wireless communication module, and then wirelessly transmit the corresponding stacker's operating data to the remote server. The remote server generates remote control commands based on the received data and sends them to the corresponding control chip. Each control chip controls the corresponding stacker to perform the corresponding remote control actions based on the received remote control commands.
[0087] Specifically, the wireless communication module includes:
[0088] The communication connection request initiation module is used to generate a communication connection request from the wireless connection requests sent by each control chip and its own unique module code and send it to the remote server. The wireless connection request carries the unique device number of the forklift, the cockpit monitoring data, and the monitoring and illuminance sensing data of the monitoring and illuminance sensing devices installed on the forklift at night for the designated area.
[0089] The communication connection disconnection module is used to disconnect the wireless communication connection with the corresponding control chip according to the communication connection disconnection notification command sent by the remote server.
[0090] The remote server includes:
[0091] The data parsing module is used to parse the received communication connection requests.
[0092] The first matching module, connected to the data parsing module, is used to match the unique module number of the parsed wireless communication module with the module numbers stored in the module number database.
[0093] If a match is successful, a wireless communication connection is established with the wireless communication module, and a second matching signal is generated;
[0094] If a match fails, the communication connection request from the wireless communication module is rejected.
[0095] The second matching module, connecting the data parsing module and the first matching module, is used to match the unique device number corresponding to each forklift machine obtained after receiving the second matching signal with the device numbers stored in the device number database.
[0096] If a match is successful, a third matching signal is generated;
[0097] If the matching fails, the wireless communication module is notified to disconnect the communication connection with the corresponding control chip.
[0098] The first judgment module, connected to the data parsing module and the second matching module, is used to determine whether the parsed cockpit monitoring data includes facial data after receiving the third matching signal.
[0099] If so, the wireless communication module is notified to disconnect from the corresponding control chip, and a first alarm signal is generated to indicate that the conditions for remote control of the corresponding forklift have not been met.
[0100] If not, the wireless communication module is instructed to maintain the communication connection with the corresponding control chip or not to respond.
[0101] The brightness value calculation module is connected to the data parsing module. It is used to calculate the brightness of any frame of the monitoring image in the monitoring data collected by the monitoring and illuminance sensing equipment and obtain the brightness value of the monitoring image.
[0102] The difference calculation module connects the brightness value calculation module and the data parsing module, and is used to calculate the difference between the calculated brightness value and the illuminance value obtained from the illuminance sensor data.
[0103] The second judgment module, connected to the difference calculation module, is used to determine whether the difference between the luminance value and the illuminance value is less than a preset difference threshold.
[0104] If so, then instruct the wireless communication module to maintain the communication connection with the corresponding control chip;
[0105] If not, the wireless communication module is notified to disconnect from the corresponding control chip and generate a second alarm signal to indicate insufficient ambient light during remote operation.
[0106] It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention.
