Description

Technical Field

[0001] This invention relates to a multi-functional control system for excavation, loading, and driving, belonging to the field of intelligent control technology for construction machinery. Background Technology

[0002] Backhoe loaders are a major member of the construction machinery family, playing a vital role in earthwork excavation, loading, and transportation. With the development of intelligent manufacturing, the requirements for electrical control technology in backhoe loaders are becoming increasingly stringent. They need to integrate more functions within a limited space, such as adding more switch input signals to the button panel, displaying more overall machine operating statuses on the instrument panel, enabling more precise control of engine status and more accurate excavation and loading operations, and adding sensors to provide drivers with a more intelligent experience and enhance human-machine interaction. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-functional control system for excavation, loading, and driving, in order to overcome the deficiencies of the prior art.

[0004] A multi-functional control system for excavating, loading, and driving includes a controller one, a controller two, a CAN1 network, and a CAN2 network. The CAN1 network integrates actuators. The controller one is communicatively connected to the CAN1 network. The CAN1 network is used to send message data to the controller one. The controller one controls the actuators through the message data.

[0005] The CAN2 network integrates a left electric control handle, a right electric control handle, and a working condition sensor. The left and right electric control handles are connected to controller two via the CAN2 network. The CAN2 network is used to send digging actions in the form of message data to controller two. Controller two controls the solenoid valves corresponding to the left and right electric control handles to realize digging and loading actions.

[0006] The operating condition sensor is used to detect the seat orientation and automatically switch the excavator loader functions via controller 2 and the CAN2 bus.

[0007] Furthermore, the actuators include a front button panel, a right button panel, a front instrument panel, a right instrument panel, an engine ECM, a transmission, a condition sensor, a light sensor, a vibration sensor, and a gyroscope. The front button panel includes status control functions for the front work lights, headlights, hazard warning lights, front wipers, and front wiper spray. The right button panel includes status control functions for the rear work lights, headlights, rear wipers, and rear wiper spray. The front instrument panel displays the status of the work lights, headlights, parking lights, hazard warning lights, side marker lights, outriggers, driving mode, steering mode, and vehicle speed. The right instrument panel displays the engine status, transmission operating status, engine speed information, fuel level information, coolant temperature information, system voltage information, and hydraulic oil status.

[0008] Furthermore, pressing the front button panel and the right button panel sends message data to controller one via the CAN1 network. After receiving the message data, controller one determines the current state and issues an instruction to control the corresponding actuator.

[0009] Furthermore, the vibration sensor and gyroscope are used to detect the degree of road bumps and vehicle tilt during driving. The detected information is sent to controller one in the form of CAN messages through the CAN1 network. Controller one processes and judges the received information. If the degree of road bumps or vehicle tilt exceeds the safety threshold set by the system, controller one sends CAN message information to the engine ECM through the CAN1 network, causing the engine ECM to reduce the engine's maximum speed to the maximum speed set by the system.

[0010] Furthermore, the light sensor is used to detect the light intensity of the surrounding environment. The detected light intensity information is sent to controller one in the form of CAN messages through the CAN1 network. Controller one processes and judges the received information. If the light intensity of the surrounding environment is lower than the light intensity required for the system to operate, controller one controls the lighting to be turned on through the CAN1 network.

[0011] Furthermore, the transmission operating status is transmitted to the first controller via the CAN1 network, and the first controller sends the information to the right instrument panel in the form of CAN messages for display.

[0012] Furthermore, the outrigger status and vehicle speed information are read from the corresponding sensor data by the controller and sent to the front instrument panel for display in the form of CAN messages.

[0013] Furthermore, the engine speed information, fuel indicator information, water temperature information, system voltage information, and hydraulic oil status are read from the corresponding sensor data by the controller and sent to the right instrument panel display in the form of CAN messages.

[0014] Furthermore, the controller reads the engine ECM information through the CAN1 network and sends the engine ECM information to the right instrument panel for display in the form of CAN messages.

[0015] Furthermore, the controller is used to send the transmission's operating status, engine speed information, fuel indicator information, water temperature information, system voltage information, hydraulic oil status, light status, driving mode, and steering mode to the front instrument panel via the CAN1 network, and display them on the front instrument panel.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention connects the various parts of the control system through the CAN bus, which can reduce the wiring harness of the whole vehicle, save assembly space, improve assembly efficiency, and realize digging and loading actions quickly and accurately, and is more intelligent.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-2As shown, a multi-functional control system for excavation, loading, and driving is disclosed, including: controller one, controller two, CAN1 network and CAN2 network. The CAN1 network integrates actuators. The controller one is communicatively connected to the CAN1 network. The CAN1 network is used to send message data to the controller one. The controller one controls the actuators through the message data.

[0028] The CAN2 network integrates a left electric control handle, a right electric control handle, and a working condition sensor. The left and right electric control handles are connected to controller two via the CAN2 network. The CAN2 network is used to send digging actions in the form of message data to controller two. Controller two controls the solenoid valves corresponding to the left and right electric control handles to realize digging and loading actions.

[0029] The operating condition sensor is used to detect the seat orientation and realizes automatic switching of the excavator loader function through controller two and CAN2 bus;

[0030] In this embodiment, the specific actuators include a front button panel, a right button panel, a front instrument panel, a right instrument panel, an engine ECM, a transmission, a condition sensor, a light sensor, a vibration sensor, and a gyroscope. The front button panel includes status control functions for the front work lights, headlights, hazard warning lights, front wipers, and front wiper spray. The right button panel includes status control functions for the rear work lights, headlights, rear wipers, and rear wiper spray. The front instrument panel displays the status of the work lights, headlights, parking lights, hazard warning lights, side marker lights, outriggers, driving mode, steering mode, and vehicle speed. The right instrument panel displays the engine status, transmission operating status, engine speed information, fuel level information, coolant temperature information, system voltage information, and hydraulic oil status.

[0031] like Figures 1-2 As shown:

[0032] Specifically, the transmission's operating status is transmitted to the first controller via the CAN1 network, and the first controller then sends the information to the right instrument panel in the form of CAN messages for display.

[0033] Specifically, the outrigger status and vehicle speed information are read from the corresponding sensor data by the controller and sent to the front instrument panel for display in the form of CAN messages;

[0034] The engine speed information, fuel indicator information, water temperature information, system voltage information, and hydraulic oil status are read from the corresponding sensor data by the controller and sent to the right instrument panel for display in the form of CAN messages;

[0035] Specifically, the controller reads the engine ECM information through the CAN1 network and sends the engine ECM information to the right instrument panel for display in the form of CAN messages;

[0036] Specifically, controller 1 is used to send the transmission's operating status, engine speed information, fuel level information, coolant temperature information, system voltage information, hydraulic oil status, light status, driving mode, and steering mode to the front instrument panel via the CAN1 network, and then display them on the front instrument panel.

[0037] like Figures 3-7 As shown, pressing the front and right button panels sends message data to controller one via the CAN1 network. Controller one receives the message data, determines the current state, and then issues commands to control the corresponding actuators. The specific operation methods for each actuator include:

[0038] A light sensor detects the ambient light intensity. The detected light intensity information is sent to Controller 1 via the CAN1 network in the form of CAN messages. Controller 1 processes and judges the received information. When the ambient light intensity is lower than the light intensity required for system operation, Controller 1 controls the lights to turn on via the CAN1 network. Figure 6 As shown.

[0039] Vibration sensors and gyroscopes are used to detect the degree of road bumps and vehicle tilt during driving. The detected information is sent to Controller 1 via the CAN1 network in the form of CAN messages. Controller 1 processes and judges the received information. When the degree of road bumps or vehicle tilt exceeds the system's specified safety threshold, Controller 1 sends a CAN message to the engine ECM via the CAN1 network, instructing the engine ECM to reduce the engine's maximum speed to the system's specified maximum speed. Figure 7 As shown.

[0040] The electric control handle is used to control the digging and loading actions. The electric control handle is connected to the controller two via the CAN2 network. Input actions are sent to the controller two in the form of CAN messages to control the corresponding solenoid valves and realize the digging and loading actions.

[0041] During loading operations, when the right electric control handle is moved forward, controller 2 outputs a signal to the boom lowering proportional valve, causing the loading boom to lower; when the right electric control handle is moved backward, controller 2 outputs a signal to the boom raising proportional valve, causing the loading boom to rise; when the right electric control handle is moved to the left, controller 2 outputs a signal to the bucket retraction proportional valve, causing the bucket to retract; when the right electric control handle is moved to the right, controller 2 outputs a signal to the bucket outward proportional valve, causing the bucket to outward.

[0042] During excavation operations, the system defaults to SAE mode, such as... Figure 8As shown. Moving the right electric control handle forward sends a signal from controller 2 to the outward swing proportional valve, causing the stick to swing outward; moving the right electric control handle backward sends a signal from controller 2 to the inward retraction proportional valve, causing the stick to retract; moving the left electric control handle forward sends a signal from controller 2 to the boom raise proportional valve, causing the boom to rise; moving the left electric control handle backward sends a signal from controller 2 to the boom lower proportional valve, causing the boom to lower. When controller 1 receives an ISO / SAE switching command, it sends it to controller 2 via the CAN2 network, and the system executes ISO mode. Moving the left electric control handle forward sends a signal from controller 2 to the outward swing proportional valve, causing the stick to swing outward; moving the left electric control handle backward sends a signal from controller 2 to the inward retraction proportional valve, causing the stick to retract; moving the right electric control handle forward sends a signal from controller 2 to the boom raise proportional valve, causing the boom to rise; moving the right electric control handle backward sends a signal from controller 2 to the boom lower proportional valve, causing the boom to lower.

[0043] The work status sensor automatically switches the operator's current backhoe loader function. By default, the driver's seat facing forward of the cab activates the loading function, while the seat facing backward activates the digging function. When the work status sensor detects the driver's seat facing forward, it automatically enables loading-related buttons and functions and disables digging-related buttons and functions. Conversely, when the sensor detects the driver's seat facing backward, it automatically enables digging-related buttons and functions and disables loading-related buttons and functions. Figure 9 As shown.

[0044] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
