Description

Technical Field

[0001] The present invention relates to the field of remote control of construction machinery, and in particular to a remote power-on system for an excavator and a control method thereof. Background Art

[0002] In the development process of remote-controlled excavators, in order to realize the remote power-on function, it is usually necessary to provide continuous power to the on-board remote control electrical components (cameras, controllers, etc.). However, this will cause the on-board electrical components to remain powered even when the excavator is not working, resulting in unnecessary power consumption. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a remote power-on system and control method for an excavator, which can solve the problem of constant power consumption of on-board electrical components caused by the remote power-on function in the development process of remote-controlled excavators, and aims to achieve remote power-on while effectively reducing the constant power consumption of on-board electrical components.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a remote power-on system for an excavator, including: a vehicle-mounted terminal and a remote terminal, wireless communication between the vehicle-mounted terminal and the remote terminal, the remote terminal can remotely control the vehicle-mounted terminal and display the information sent by the vehicle-mounted terminal, the vehicle-mounted terminal can receive instructions from the remote terminal controller, and control the power on and off of the vehicle-mounted components of the excavator according to the instructions.

[0005] Furthermore, the vehicle-mounted end includes: an intelligent remote control switch, an image system, an on-board execution system, a POE switch, and a communication system. The intelligent remote control switch is connected to a power supply, and is connected to the on-board execution system, a POE switch, a communication system, and an image system. The power supply of the on-board execution system and the POE switch is controlled by the intelligent remote control switch. The POE switch is connected to the communication system and the image system. The intelligent remote control switch controls the power supply of the image system and the communication system through the POE switch. The on-board execution system is used to control whether the on-board components of the excavator are powered.

[0006] Furthermore, the vehicle-mounted terminal also includes: a power management module, in which a battery is provided for storing energy, the intelligent remote control switch is connected to the power supply through the power management module, and the power management module is also connected to the image system.

[0007] Furthermore, the power management module charges and stores the power when there is input power, and discharges the power when there is no input power. At the same time, it can collect the power status of the intelligent remote control power-on system and the voltage status of the vehicle circuit in real time, and feed back to the remote end.

[0008] Furthermore, the remote end includes: a remote control switch remote controller, a display system, and a data instruction system.

[0009] A control method for a remote power-on system of an excavator, comprising the following steps: S01. Control the intelligent remote control switch to work through the remote control switch remote controller, and power on the image system, vehicle-mounted execution system, POE switch, and communication system; S02. The image system sends data to the remote display system through the communication system, and waits until all the images in the remote display system are correctly displayed; S03. The vehicle-mounted execution system is only allowed to receive the instruction to power on the vehicle-mounted execution system issued by the remote data instruction system, which serves as the basis for remote operation instructions.

[0010] Further, in the steps S01 - S03, the power management module real-time collects the power state V1 of the intelligent remote control power-on system and the vehicle-mounted circuit voltage V2. The power management module feeds back the information to the image system, and the image system feeds it back to the remote end through the communication system for display.

[0011] Further, it is also necessary to judge and perform power-on and power-off operations according to the vehicle-mounted voltage situation: 1) When V2 > V2p2, any instruction can be issued; 2) When V2p1 < V2 < V2p2, it satisfies basically power-on but the voltage is insufficient. The operator can be prompted at the remote control end to charge the vehicle in time, or the start instruction can be automatically executed for vehicle-mounted charging; 3) When V2 < V2p1 and V1 < V1p, the remote controller directly executes the control of prohibiting power-on and starting. At the same time, the remote display system prompts the operator to go to the vehicle to charge until the situation of 1) is reached and then an instruction can be issued.

[0012] Further, in the step S03, it is also necessary to ensure that when V2 reaches the stable value V2s, the vehicle-mounted execution system is only allowed to receive the instruction to power on the vehicle-mounted execution system issued by the remote data instruction system.

[0013] Further, when the image system or other networks are unstable and need to stop, a power-off instruction is issued through the remote control switch remote controller at the remote end to stop the power supply of all devices.

[0014] The beneficial effect of the present invention is that while realizing remote power-on, it effectively reduces the power consumption of vehicle-mounted electrical components when constantly powered on, and increases the service time of the storage battery. Brief Description of the Drawings
