All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The excavator control method, device and excavator of the present invention are described below with reference to fig. 1 to 5.
Fig. 1 is a flowchart illustrating an excavator control method according to an embodiment of the present invention. As shown in fig. 1, the present embodiment provides an excavator control method, which is applied to an excavator with multiple control modes, and the method can be executed by the excavator or software and/or hardware therein, and the method at least includes:
step 101, obtaining the value of a first zone bit of each control mode; the value of the first flag bit is used for representing whether each control mode is available or not; and determining the available control mode with the highest priority in each control mode according to the value of the first flag bit of each control mode and the priority of each control mode.
The plurality of control modes may include a manual control mode and a remote control mode, among others.
The manual control mode is a mode in which the excavator is directly and manually operated.
The remote control mode is a mode for remotely controlling the excavator. Illustratively, the remote control modes may include, but are not limited to, a first remote control mode, a second remote control mode, and a third remote control mode.
The first remote control mode is a mode in which operation information transmitted by the remote control device is received based on the wireless local area network. The operation information is used to control the excavator to perform work. The wireless local area network may be, but is not limited to, a Wi-Fi network or an Ultra Wide Band (UWB) network, etc. The excavator can be provided with a communication device, and the communication device comprises a wireless network transceiver module which is used for providing a wireless local area network and receiving signals from the wireless local area network. The remote control device can be a remote control handle, and can also be a mobile terminal such as a mobile phone. An Application (APP) is installed in the mobile terminal. The remote control equipment can be directly connected with the excavator through the wireless local area network, the remote control equipment sends the operation information to the wireless network transceiver module of the communication equipment in the excavator through the wireless local area network, and then the wireless network transceiver module sends the operation information to the controller of the excavator, so that remote control is realized. Generally, the wireless lan covers a limited distance, and thus the first remote control mode is suitable for a scenario in which remote control is performed within a certain distance range on the site where the excavator is located.
The second remote control mode is a mode in which operation information transmitted by the remote control device is received based on the mobile network. The Mobile network may be a cellular network, and may be, but not limited to, a fourth Generation Mobile Communication Technology (4G), a fifth Generation Mobile Communication Technology (5G), a Global Positioning System (GPS), or the like. The communication equipment in the excavator further comprises a mobile network transceiver module, and the mobile network transceiver module can be connected with a mobile network base station. The remote control device can also be connected with a mobile network base station, and can be a remote control handle or a mobile terminal such as a mobile phone. An Application (APP) is installed in the mobile terminal. The remote control equipment can be connected with the excavator through a mobile network, the remote control equipment sends the operation information to a mobile network transceiver module of communication equipment in the excavator through the mobile network, and then the mobile network transceiver module sends the operation information to a controller of the excavator, so that remote control is realized. In the area covered by the mobile network signal, remote control can be carried out through the second remote control mode.
The third remote control mode is a mode in which collected work environment information is transmitted to the remote control device based on the mobile network and operation information transmitted by the remote control device is received. Likewise, the communication device in the excavator may include a mobile network transceiver module capable of connecting to a mobile network base station. The remote control device can comprise a communication device, wherein the communication device comprises a mobile network transceiver module which can be connected with a mobile network base station. The remote control device can be connected with the excavator through a mobile network. In implementation, the excavator may be provided with an audiovisual information acquisition module, and the audiovisual information acquisition module is used for acquiring the operation environment information of the excavator. The remote control device may also have a remote cab and an audio-visual display. The audio-visual information acquisition module in the excavator acquires the operation environment information through the camera and the radio and sends the operation environment information to the audio-visual display device of the remote control equipment through the mobile network for playing so that a driver can see the operation environment of the site where the excavator is located and carry out remote control operation. The third remote control mode is suitable for a scene where it is inconvenient to see the work environment on the site where the excavator is located.
In practical application, the excavator can comprise a plurality of remote control modes in a plurality of control modes, the remote control modes can be flexibly used, and the applicability is high.
Wherein the first flag bit of the control mode is used for storing a value for indicating whether the control mode is available or not. A corresponding first flag bit may be set in advance for each control mode, for example, the first flag bit of the manual control mode may be set to a, where a is 1, and the flag bit indicates that the manual control mode is available, and a is 0, and indicates that the manual control mode is not available; a first flag bit of the first remote control mode may be set to b, where b is 2, to indicate that the first remote control mode is available, and b is 0, to indicate that the first remote control mode is not available; a first flag bit of the second remote control mode may be set to c, where c is 3, which indicates that the second remote control mode is available, and c is 0, which indicates that the second remote control mode is not available; the first flag bit of the third remote control mode may be set to d, where d is 4, which indicates that the third remote control mode is available, and d is 0, which indicates that the third remote control mode is not available.
In an implementation, the value of the first flag bit of each control mode may be updated according to the switch state of each control mode.
When the switch of the manual control mode is turned on, the manual control mode is determined to be available, and when the switch of the manual control mode is turned off, the manual control mode is determined to be unavailable, and based on the determination, the value of the first flag bit of the manual control mode can be updated. For example, when the manual control mode fails, the switch of the manual control mode is turned off, and the manual control mode is not available, at this time, the value of the first flag bit of the manual control mode may be updated.
When the excavator is connected with the remote control equipment based on the network corresponding to the remote control mode, the excavator can communicate with the corresponding remote control equipment in the remote control mode, and the remote control mode is provided with a basis of remote control. For example, if the adopted remote control mode has a fault, for example, the mobile network signal is unstable, the remote control device can be accessed through other remote control modes, and in these cases, the value of the first flag bit of the remote control mode can be updated.
In the implementation, the value of the first flag bit of each control mode can be obtained in real time, and then the available control mode with the highest priority in each control mode is determined in real time according to the value of the first flag bit of each control mode and the priority of each control mode, so that the dynamic switching of the control modes is realized quickly.
And 102, determining the available control mode with the highest priority as the current control mode of the excavator.
According to the excavator control method provided by the embodiment, the value of the first flag bit of each control mode can be obtained in real time, and the value of each first flag bit can represent whether each control mode is available, so that the available control mode with the highest priority in each control mode can be determined according to the value of the first flag bit of each control mode obtained in real time and the priority of each control mode.
It is understood that, in the case where the current control mode of the excavator is determined, the excavator may be controlled to perform work based on the current control mode of the excavator.
Based on the above embodiment, the excavator further has a second flag bit; correspondingly, the determining the available control mode with the highest priority as the current control mode of the excavator may include: and if the available control mode with the highest priority is determined in the control modes, assigning the second zone bit to the value of the first zone bit of the available control mode with the highest priority, and determining the current control mode of the excavator to be the available control mode with the highest priority.
The second flag bit is used to store a determination result for determining the available control mode with the highest priority among the control modes. In an implementation, the second Flag may be preset, for example, the second Flag is Flag.
And if the available control mode with the highest priority is determined, assigning the second zone bit as the value of the first zone bit of the available control mode with the highest priority, wherein the value of the first zone bit of the available control mode with the highest priority is the value for representing the availability of the control mode. For example, if the available control mode with the highest priority is determined to be the manual control mode, the Flag is 1, if the available control mode with the highest priority is determined to be the first remote control mode, the Flag is 2, if the available control mode with the highest priority is determined to be the second remote control mode, the Flag is 3, and if the available control mode with the highest priority is determined to be the third remote control mode, the Flag is 4.
Therefore, the available control mode with the highest priority can be quickly obtained according to the value of the second zone bit.
Based on this, the excavator control method of the present embodiment may further include: and if the available control mode with the highest priority is not determined in the control modes, assigning the second zone bit to a preset value, and determining that the excavator does not execute any control mode currently.
The preset value may be set according to actual conditions, for example, the preset value may be set to 0, that is, when Flag is equal to 0, it is characterized that there is no available control mode at present, which is also referred to as an idle control mode.
In the case of the idle control mode, if any control mode is not executed, the control of the excavator for work may be stopped. Therefore, when the excavator fails and cannot work, the operation mode can be automatically switched to the idle control mode, so that the excavator is stopped to be controlled to work, and the safety of equipment and personnel is ensured.
Based on the above embodiment, the determining, according to the value of the first flag bit of each control mode and the priority of each control mode, an available control mode with the highest priority in each control mode may include:
selecting one control mode from the control modes as a control mode of the current processing according to the order of the priority of the control modes from high to low, and executing the following processing operations on the control mode of the current processing:
if the value characterization of the first flag bit of the currently processed control mode is determined to be available, taking the currently processed control mode as the available control mode with the highest priority, and stopping selecting the control mode from the control modes;
and if the value of the first flag bit of the currently processed control mode is determined to indicate that the characterization is unavailable and the control mode in each control mode is not selected completely, continuing to select the control mode from each control mode.
In addition, if the value of the first flag bit of the control mode currently processed is determined to indicate that the control mode is unavailable and the control mode in each control mode is selected, determining that the excavator does not have any available control mode currently.
In this embodiment, the control modes are processed according to the order of priority, and once an available control mode is determined, a subsequent selection process of the control mode is not required, so that the available control mode can be determined quickly and accurately.
Of course, the available control mode with the highest priority among the control modes may be determined in other manners, for example, first determining whether each control mode is available, and then selecting the available control mode with the highest priority from the available control modes.
Based on the above embodiment, the priority of the manual control mode is higher than the priority of the remote control mode. In consideration of safety, the manual control mode has the highest priority, namely the priority of the manual control mode is higher than that of the remote control mode, when a switch of the manual control mode is turned on, the manual control mode is preferentially adopted to control the excavator, a driver reasonably controls the excavator according to actual conditions to ensure operation safety, and when the switch of the manual control mode is not turned on, the remote control mode is adopted again, so that the operation safety is improved.
Based on the above embodiments, it is exemplary that the priorities of the first remote control mode, the second remote control mode, and the third remote control mode are sequentially lowered.
Considering that the first remote control mode is suitable for a scene of performing remote control within a certain distance range on the site of the excavator, and an actual situation that no mobile network signal or a network signal is poor may exist in an operation environment of the excavator, the audio-visual information acquisition module or the remote cab may also have a fault, at this time, if the excavator can be directly connected with the remote control equipment through the wireless local area network, stable remote control operation can still be realized, and therefore, the first remote control mode is preferentially adopted, the remote control effect is better, namely, the priority of the first remote control mode is set to be higher than the priorities of the second remote control mode and the third remote control mode.
When the distance between the excavator and the remote control equipment is long, the distance exceeds the coverage range of the wireless local area network, and if the excavator can be connected with a mobile network, the excavator can be connected with the remote control equipment through the mobile network, so that remote control operation is performed.
When the remote control device is not convenient to see the site of the excavator, a third remote control mode can be adopted.
The excavator control method provided by the embodiment of the invention is described in more detail below by taking a specific application scenario as an example.
In this embodiment, the excavator has four control modes, including a manual control mode, a first remote control mode, a second remote control mode, and a third remote control mode, with priorities from high to low.

Based on this, the first remote control mode is also called mobile terminal Wi-Fi remote control mode.
In the second remote control mode, the remote control equipment is a mobile terminal, the mobile terminal can be connected with a mobile network base station and is connected with the excavator through a 4G or 5G network, the remote control equipment sends the operation information to a mobile network transceiver module of the communication equipment in the excavator through the 4G or 5G network, and then the mobile network transceiver module sends the operation information to a controller of the excavator, so that remote control is achieved.

In this case, the remote control device is also referred to as a central control terminal, and based on this, the third remote control mode is also referred to as a central control terminal network remote control mode.
Based on this, the control method of the excavator is executed by the controller of the excavator, as shown in fig. 3, specifically as follows:
