The following describes a remote control method for a working machine according to the present invention with reference to fig. 1 and fig. 2, where an execution main body of the method may be a controller on a device side, or a cloud side, or an edge server.

The working machine may be a mini excavator, a medium excavator, a large excavator, a tower crane, a truck crane, a pile driver, a concrete machine, a road roller, a mixer truck, a boring machine, a pump truck, or the like.

As shown in fig. 2, the remote control receiver of the working machine includes a first communication module and a second communication module, both the first communication module and the second communication module can receive the remote control signal sent by the remote controller, and the working machine analyzes the remote control information to obtain a corresponding control instruction.

As shown in fig. 1, the method for remotely controlling a work machine according to an embodiment of the present invention includes steps 110 to 130.

And step 110, controlling the second communication module to be opened or closed based on the first remote control signal received by the first communication module.

The first communication module is in a standby state, the first communication module can receive a remote control signal from the remote control signal sending end, and the remote control signal sending end is in communication connection with the operation machine through the first communication module.

In this step, the low-power remote control standby state of the working machine is realized by keeping the first communication module on, so that the remote control standby time of the working machine can be prolonged, and the power supply of the working machine cannot be lack of power.

The first communication module receives a first remote control signal sent by the remote control signal sending end, analyzes the first remote control signal and controls the second communication module to be opened or closed.

In the step, after the remote control signal sending end is in communication connection with the working machine through the first communication module, the working machine starts the second communication module with high power consumption and high transmission rate.

The second communication module is used for receiving and transmitting signals after being started, and the remote control signal sending end realizes operation remote control on the operation machine through the second communication module.

After the remote control signal sending end is in communication connection with the operation machine through the first communication module, the second communication module can be controlled to be closed based on the first remote control signal.

The second communication module is in a closed state, so that the power consumption of the remote control receiver of the operation machine can be reduced, the standby time of the remote control receiver is prolonged, and the interference of the second communication module on the communication of the first communication module can be effectively avoided.

And 120, outputting a control instruction for controlling the action of the executing mechanism to the executing mechanism of the working machine based on the second remote control signal received by the second communication module.

In this step, the second communication module is in an open state, and can receive the second remote control signal sent by the remote control signal sending end, and analyze the second remote control signal to obtain a control instruction for controlling the action of the execution mechanism.

In actual execution, the control instruction is output to the corresponding execution mechanism, the operation of the working machine is controlled, and corresponding operation is executed.

A specific embodiment is described below.

Taking an excavator as an example, the actuating mechanism of the excavator comprises a power device, a working device, a slewing mechanism, a control mechanism, a transmission mechanism, a travelling mechanism, auxiliary facilities and the like.

And the WIFI module receives a second remote control signal of the remote control rotation mechanism rotation operation sent by the remote control signal sending end.

And the excavator analyzes the second remote control signal to obtain a corresponding control instruction, and sends the control instruction to the swing mechanism to control the swing mechanism to swing.

It can be understood that after the remote control signal sending end establishes communication connection with the second communication module, the second communication module has high transmission rate and long remote control range distance, which is beneficial to improving the operation efficiency of remote control operation of the operation machine and widening the remote control operation range.

And step 130, controlling the first communication module to be in an open state and closing the second communication module based on the third remote control signal received by the first communication module or the second communication module.

In this embodiment, the second communication module receives a third remote control signal sent by the remote control signal sending end, and the work machine analyzes the third remote control signal, so as to control the first communication module to be turned on and control the second communication module to be turned off.

It can be understood that after the remote control operation is finished, the operation machine can greatly prolong the standby time of the operation machine in the remote control state by keeping the first communication module with low power in standby state, and can also start the second communication module with high transmission rate in time through the first communication module, thereby improving the operation efficiency and widening the remote control operation range.

According to the remote control method of the working machine, the first communication module controls the second communication module to be opened or closed in time, the second communication module is used for realizing remote control operation of the working machine, and the second communication module is closed after the operation is finished, so that the standby time of the remote control state of the working machine can be greatly prolonged, the operation efficiency and the operation range of the remote control operation are improved, and the accident rate is effectively reduced.

In some embodiments, the power consumption of the first communication module is less than the power consumption of the second communication module.

The first communication module may be a remote control module with low power consumption and short remote control distance, for example, the first communication module may be a bluetooth module, a ZigBee module, or an NFC module.

The second communication module may be a remote control module with a high transmission rate, high power consumption and a short remote control distance, for example, the second communication module may be a WIFI module, a 4G module or a 5G module.

In some embodiments, prior to step 110, a first communication module of a remote control receiver of the work machine is in an on state and a second communication module is in an off state.

After the working machine is powered on, the first communication module is in a standby state, the power consumption of the first communication module is low, and the first communication module can keep a long standby time.

In actual execution, the operating machine and the remote control signal sending end communicate through the first communication module or the second communication module, wherein after the operating machine is powered on, the first communication module is in a normally open standby state, the remote control signal sending end is in communication connection with the first communication module, and after the remote control signal sending end is opened and connected with the second communication module for communication, the operating machine automatically closes the first communication module.

In some embodiments, after the work machine starts the second communication module, the second communication module is connected to the remote control signal sending end, and the second communication module receives a remote control signal for controlling the first communication module to be closed.

In actual execution, the second communication module is opened and connected with the remote control signal sending end, and then the corresponding remote control signal can be received, and the first communication module is opened or closed.

For example, after the work of the work machine is finished, the remote control signal sending end sends a corresponding remote control signal to the second communication module, the first communication module is turned on, the second communication module is turned off, the first communication module with low power is kept in a standby state, and the standby time of the remote control function of the work machine is prolonged.

In some embodiments, the communication distance of the first communication module is less than the communication distance of the second communication module in the work machine.

The first communication module can realize the connection with the remote control signal transmitting end and partial remote control operation of the working machine in a short communication distance range, is beneficial to prolonging the remote control operation time of the working machine and storing electric energy for the subsequent long-distance remote control operation.

The second communication module can receive the remote control signal sent by the remote control signal transmitting terminal within a longer communication distance range, and the second communication module is large in power consumption, high in transmission rate and capable of guaranteeing the safety of long-distance remote control operation.

For example, the excavator utilizes the bluetooth low energy module to perform remote control operation within a range of 10 meters, and can realize remote control connection under the conditions of muddy field, wading and uncertain danger of operation environment, and open the WIFI module with high transmission rate, thereby realizing remote control operation within a remote control range of more than 100 meters.

In some embodiments, after step 110, the method for remotely controlling a work machine further comprises: and closing the second communication module based on the fourth remote control signal received by the first communication module.

In this embodiment, the second communication module and the first communication module of the working machine are in an open state, and the first communication module is in communication connection with the remote control signal transmitting terminal to receive the fourth remote control signal, so as to control the second communication module to be closed.

In actual execution, the first communication module is opened and connected with the remote control signal sending end, and then the corresponding remote control signal can be received, and the second communication module is opened or closed.

For example, the remote control signal sending end sends a corresponding remote control signal to the first communication module, the second communication module is closed, and the second communication module is in a closed state, so that electric energy of the working machine can be saved, and communication interference between the first communication module and the second communication module can be effectively avoided.
