[0029] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

In the accompanying drawings and the following description, known structures and techniques are not shown to avoid causing unnecessary ambiguity to the present invention.

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In the description of this application, unless otherwise specified, “at least one” means one or more than one. For example, at least one USB device means one USB device or more than one USB device.

[0033] Furthermore, the terms "including," "having," and any variations thereof, mentioned in the description of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0034] Currently, achieving both efficient rescue operations and the safety of rescuers is a critical requirement. However, existing excavators are generally controlled using the CAN bus, and their cabs cannot be detached. When a disaster strikes, the driver is often required to drive the excavator to the rescue site, which makes it difficult to guarantee the safety of rescuers.

[0035] Based on this, an excavating mechanism and system provided by an embodiment of the present invention can solve the technical problem of low safety assurance level of current excavators in the prior art.

[0036] To facilitate understanding of this embodiment, an excavation mechanism and system disclosed in an embodiment of the present invention are first introduced in detail.

[0037] Example 1:

[0038] An embodiment of the present invention provides an excavation mechanism, such as Figure 1 As shown, the excavation mechanism 100 includes: an excavator main body equipment 101, an operation control device 102, a movement device 103 and a transmission device 104.

[0039] The excavator main body is used to perform excavation operations. The operation control device is used to control the operation of the excavator main body in response to control operations on the excavator main body. Furthermore, the operation control device is provided on the motion device, and the motion device is used to control the movement of the operation control device.

[0040] Furthermore, the moving device is movably connected to the main excavator device. The transmission device is provided on the main excavator device. The moving device is moved from the ground to the main excavator device via the transmission device, or from the main excavator device to the ground via the transmission device.

[0041] The excavation mechanism provided in the embodiment of the present application can be used as an operationally detachable excavator. By providing a motion device capable of controlling the movement of the operation control device and a transmission device capable of moving the motion device between the ground and the excavator main equipment, the separation function of the operation control device and the excavator main equipment is realized, so that the operation control device can be separated from the excavator main equipment, so that the operator of the excavator main equipment can control the excavator main equipment at a location far away from the excavation operation site.

[0042] In some embodiments, the operation control device is arranged in the operation room, and the operation room (ie, the driving room) is arranged on the motion device.

[0043] For example, as shown in Figures 2(a), 2(b), 2(c), and 2(d), when moving away from a disaster site, the cab can be combined with other parts of the excavator to reach the vicinity of the disaster site. The cab can then be separated from the main body of the excavator and parked at an appropriate distance from the disaster site.

[0044] The operating cab realizes the detachable cab structure of the excavator, which is convenient for the operator to control the main body of the excavator.

[0045] In some embodiments, when the moving device is on the ground, the operation control device is connected to the main equipment of the excavator via wireless communication.

[0046] Through the wireless communication connection between the operation control device and the main equipment of the excavator, a wireless control method of the excavator is realized, which is convenient for the operator to remotely control the main equipment of the excavator.

[0047] In some embodiments, when the motion device is located on the main equipment of the excavator, the operation control device is connected to the main equipment of the excavator via wired and / or wireless communication.

[0048] The operation control device is connected to the main excavator equipment through wired and / or wireless communication, which does not affect the accurate and reliable control function of the operation control device on the main excavator equipment when the operation control device and the main excavator equipment are combined.

[0049] In some embodiments, the excavation mechanism further includes: a distance sensor and a communication control device. The distance sensor and the communication control device are connected.

[0050] The distance sensor is used to detect the actual distance between the operating control device and the main equipment of the excavator.

[0051] The communication control device is used to control the operation control device to be connected to the excavator main equipment through a first wireless communication device when the actual distance is less than a preset distance, and to control the operation control device to be connected to the excavator main equipment through a second wireless communication device when the actual distance is greater than or equal to the preset distance.

[0052] By switching between the two wireless control modes according to different distances, the control of the excavator can be more targeted and more suitable for the actual distance conditions on site, making the control function of the operating control device on the excavator more reliable.

[0053] In some embodiments, the first wireless communication device is configured to perform wireless communication via UWB and / or IEEE 802.11a.

[0054] For example, when the actual distance between the operating control device and the main equipment of the excavator is relatively close, the excavator can be controlled by combining UWB and IEEE802.11a transmission technology. Figure 3 As shown, after the control signal is converted into a control signal by the data conversion module, it is wirelessly transmitted using a signal transmitter and a signal receiver combined with UWB and IEEE802.11a, and then converted by the data conversion module to obtain a control signal to control the actuator, thereby realizing the transmission of the control signal through a more suitable wireless device in a closer distance situation.

[0055] In some embodiments, the second wireless communication device is configured to perform wireless communication via 5G.

[0056] For example, when the actual distance between the operation control device and the excavator main body device is far, such as in the case of a large disaster site area, wireless control based on 5G communication technology is used between the two. Figure 4 As shown in the figure, after the control signal is converted by the data conversion module, it is wirelessly transmitted by using the NG-RAN and 5GC of 5G, and then converted by the data conversion module to obtain the control signal to control the actuator, so as to realize the transmission of the control signal by a more suitable wireless device in a long distance condition.

[0057] Therefore, the application provides a cab detachable excavator based on wireless communication, which uses a combination of reliable UWB and IEEE802.11a transmission technology to control the excavator in a short distance, and uses wireless control based on 5G communication technology to control the excavator in a long distance, so as to ensure reliable wireless communication process in both long distance and short distance conditions.

[0058] In some embodiments, the operation control device is further configured to control the movement direction and movement speed of the movement device in response to a control operation on the movement device.

[0059] By the operation control device capable of controlling the movement device, the operator can control the movement direction and movement speed of the movement device and the cab in the cab, facilitating the operator to flexibly grasp the position of himself.

[0060] Embodiment two:

[0061] The excavating system provided by the application comprises a terminal device and the excavating mechanism provided in the first embodiment.

[0062] The terminal device is wirelessly connected with the movement device in the excavating mechanism.

[0063] The terminal device is configured to control the movement direction and movement speed of the movement device.

[0064] By the terminal device capable of controlling the movement direction and movement speed of the movement device, the operator can control the specific movement of the cab when he is far away from the construction site, without the need for the operator to be in the cab, facilitating the operator to remotely control the specific position of the cab.

[0065] In some embodiments, the terminal device is further configured to control the movement device to move from the ground to the excavator main body device by the conveying device, or control the movement device to move from the excavator main body device to the ground by the conveying device in response to a control operation on the movement device.

[0066] By using a terminal device that can control the movement direction and speed of the motion device, the operator can control the cab to move to the excavator main equipment or from the excavator main equipment to the ground at a place far away from the construction site. The operator does not need to be inside the cab, which makes it convenient for the operator to remotely control the cab to move to the excavator main equipment or from the excavator main equipment to the ground.
