[0025] In view of the above problems, the embodiments of this application provide a remote control excavator control system, and the technical solutions of the embodiments of this application are described in detail below with reference to the drawings.

[0026] As Figure 1A remote control excavator control system as shown includes a vehicle body and its own electronic control system, and further includes: a vehicle terminal 1, a 5G communication module, and a remote control terminal 2. In this application, the original on-site manual control method is modified to a remote control method. Therefore, the original driving control is transformed. Specifically, while adding remote control, the original control is transformed to adapt to remote control. This application specifically includes a vehicle terminal 1, a 5G communication module, and a remote control terminal 2. Among them, in the vehicle terminal 1, the original hydraulic pilot system is transformed, and a video acquisition module, a data acquisition module, and a networking module are added. The 5G communication module is mainly used for wireless communication to connect the vehicle terminal 1 and the remote control terminal 2 to achieve remote communication control. The remote control terminal 2 includes a controller, an industrial computer, a display screen, an integrated handle, a foot pedal, and buttons; among them, the display screen, the integrated handle, the foot pedal, and the buttons are electrically connected to the industrial computer, and the industrial computer is electrically connected to the controller.

[0027] Specifically, each oil circuit of the hydraulic pilot system is set to two paths, and a pilot solenoid valve is arranged on each oil path for convenient control. The pilot solenoid valve is electrically connected to the networking module; a data acquisition module is arranged on the vehicle body. The data acquisition module is connected to the hydraulic pilot system and the electronic control system of the vehicle body itself. A video acquisition module is arranged on the vehicle body, and the data acquisition module, the electronic control system, and the video acquisition module are connected to the networking module.

[0028] In this application, the video acquisition module is composed of a camera. The camera is arranged around the front, back, left, and right of the vehicle body to collect the real-time environment around the vehicle body and feedback it to the display screen to display the real-time working conditions. The data acquisition module is used to collect and feedback the data of the hydraulic pilot system, the pilot solenoid valve, and the electronic control system, and display this data on the display screen for the operator to view. These data and control signals interact with the data and signals of the vehicle terminal 1 through the networking module and the 5G communication module with the remote control terminal 2. The data and signals interact with the remote control terminal 2 so that the controller of the remote control terminal 2 can remotely control the vehicle terminal 1 through the data and signals. The controller is connected to the display screen to display the real-time data of the vehicle terminal 1. In this way, various data conditions of the vehicle terminal 1 and the remote control terminal 2 can be displayed separately at the same time.

[0029] The integrated handle, foot pedal, and buttons of this application are used to simulate the actual situation in the cab of an actual vehicle and are restored in proportion. Therefore, the integrated handle includes all the operating handles in the original vehicle cab, and each handle is integrated according to the original position and function.

[0030] In this way, this application actually constructs a cab remotely, places all the original handles, pedals, and buttons in the cab, and then feeds back these actual control operations into the industrial control computer to form a control current. Then, after being converted into a control signal by the controller, the control signal is sent to the networking module of vehicle terminal 1 through the 5G communication module and is converted back into a control signal or current, and then fed back to the corresponding controller or hydraulic pilot system by the networking module to complete remote control. Thus, the excavator that originally required on-site operation can be remotely controlled after being transformed by the technical solution of this application, thereby avoiding the situation where workers are in this environment for a long time, with high safety risks and unguaranteed occupational health.

[0031] Finally, it should also be noted that in this article, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "including", "comprising", or any other variant are intended to cover non-exclusive inclusion, so that a process, method, article, or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article, or device.

[0032] The unit described as a separate component may or may not be physically separated, and the component shown as a unit may or may not be a physical unit, that is, it may be located in one place, or it may be distributed to multiple network units. Some or all of the units can be selected according to actual needs to achieve the purpose of the solution of this embodiment.

[0033] In one embodiment, this project is an excavator remote control system based on 5G, which is mainly divided into two parts: vehicle terminal 1 and remote control terminal 2.

[0034] The vehicle terminal adds video acquisition, data acquisition, and networking modules on the basis of the original vehicle to achieve the upload of video signals and vehicle working condition data.

[0035] The remote control terminal uses a simple console, which integrates original control modules such as handles, pedals, buttons, and controllers, as well as an industrial control computer, a display screen, etc., to achieve the issuance of control instructions and the display of video and data signals.

[0036] After ensuring the safety of the vehicle, turn on the vehicle's main power supply. Switch from the local switch to the remote control switch.

After entering the screen desktop, click the icon "Remote Control System.exe" on the screen desktop to start the remote control system. After the system starts, the display screen shows the remote control platform interface.

[0037] After successful login, the vehicle video and current working condition information will be displayed on the main interface of the software.

[0038] Observe the vehicle conditions, including the following matters:

[0039] ① Through the video interface of the software, observe the environment around the vehicle to ensure the safety of the surrounding environment.

[0040] ② Observe whether there is a fault code displayed on the software. If there is a fault code, contact the on-site personnel in time to troubleshoot the problem.

[0041] ③ Ensure that the safety handle is shown as "off" in the parameter area of the software.

[0042] ④ After confirming the safety around the vehicle and being able to remotely control, turn the key to the ON state (the second gear from left to right), and power on the operation components such as the switch panel and the controller.

[0043] ⑤ Press the horn (the right button on the left handle) to sound a warning to the people around the vehicle to avoid the vehicle.

[0044] ⑥ After starting, turn on the safety handle, and the display interface will show the "on" state of the safety handle.

[0045] ⑦ At this time, normal remote control operations can be carried out: operate the handle and the walking pedal to perform task actions, which are consistent with the operation instructions of the machine. Pay attention to the following matters at all times during the operation:

[0046] ① Observe the on-site situation on the display screen in real time during the action process, including video and data display. In case of danger, turn off the safety handle in time and stop the action.

[0047] ② When the display interface shows a fault alarm code, immediately turn off the safety handle and stop the action, and go to the vehicle end to check and troubleshoot the fault.

[0048] ③ After the operation is completed, turn off the safety handle, turn the key to the OFF state (the first gear from left to right), and cut off the power supply of the console.

[0049] The above has described the embodiments of the present application. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
