Description

Technical Field

[0001] The utility model relates to the field of electrical control of snow removal vehicles, and particularly relates to an intelligent electrical control system for a multi-functional snow removal vehicle. Background Art

[0002] At present, the market share of snow removal vehicles is increasing day by day, and mechanized snow removal operations have become the first choice. The control methods of most snow removal vehicles in the same industry are not advanced enough and still remain in the traditional control mode, lacking intelligent components. For example, human-machine interaction, intelligent spreading, intelligent control, etc. are all the current advanced advantages of snow removal vehicle control. Snow removal vehicles in the same industry cannot timely understand the operation status of the equipment in the cab. Most of them are manually operated according to the senses, without adopting an intelligent control method with a controller as the core, and without collecting the chassis vehicle speed signal. The spreading density and spreading width can be adjusted arbitrarily, and the spreading amounts achieved by the above various blind factors are all uneven, failing to achieve the expected effect. All of the above are sufficient to show that users have wasted a large amount of financial and material resources and affected the operation efficiency. Therefore, from the perspective of intelligent high-end, intelligent control is an inevitable trend. Content of the Utility Model

[0003] In view of the above problems existing in the prior art, the utility model provides an intelligent electrical control system for a multi-functional snow removal vehicle, which uses the vehicle specification protocol CANBUS bus for networking, gets rid of the traditional switch control mode, adds intelligent control components to the actions of the machine tools, and improves the operation quality and efficiency, the convenience of operation and the humanized color of human-machine interaction.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: an intelligent electrical control system for a multi-functional snow removal vehicle, including: a human-machine display, a bus panel, a voice alarm device, a water level sensor, an upper-mounted controller, a chassis controller, and an actuator. The human-machine display, the bus panel, the voice alarm device, the upper-mounted controller and the chassis controller perform real-time communication by using a bus. The water level sensor is connected to the input port of the upper-mounted controller, and the output end of the upper-mounted controller is connected to the actuator for controlling the actuator to work.

[0005] Further, the actuator includes: a front snow brush solenoid valve, a middle ice-breaking roller solenoid valve, a rear snow brush solenoid valve, a spreader control mechanism, a spraying device solenoid valve, and an auxiliary device. The front snow brush solenoid valve, the middle ice-breaking roller solenoid valve, the rear snow brush solenoid valve, the spreader control mechanism, the spraying device solenoid valve, and the auxiliary device are all connected to the output end of the upper-mounted controller.

[0006] Further, the spreader control mechanism includes: a spreader solenoid valve for controlling the spreader to work, a spreader lighting device for lighting, an electric push rod for adjusting the spreader to work, and a radiator for spreading machine heat dissipation.

[0007] Further, the auxiliary device includes: a conversion module, a vehicle-mounted lighting device, and a combined fan. The conversion module is connected to the output end of the upper-mounted controller, and the vehicle-mounted lighting device and the combined fan are connected to the output end of the conversion module.

[0008] Further, the bus is a CANBUS bus.

[0009] Further, the bus panel sends a control instruction to the upper-mounted controller. After logical analysis and calculation, the upper-mounted controller outputs an execution command. At the same time, the controller sends it to the human-machine display and the voice alarm device through the bus to display the working state of the device. The voice alarm device gives a voice prompt for abnormal signals. During the intelligent spreading process, the upper-mounted controller will collect the vehicle speed message information of the chassis controller to provide a data operation basis for the next high-precision spreading, so as to ensure that the unit spreading amount does not change with the vehicle speed.

[0010] Further, when the bus panel switches to the manual mode, the execution mechanism is controlled by the upper-mounted controller to work, and corresponding action controls can be performed on the front snow brush, the middle ice-breaking roller, the rear snow brush, the spreading device, and the spraying device. The bus panel realizes multi-functional buttons through program definition. A total of 3 groups of multi-functional buttons are defined, and one key can complete the control, namely the work, floating, and stop of the front snow brush, the work, floating, and stop of the middle ice-breaking roller, and the work, floating, and stop of the rear snow brush, providing excellent convenience in operation.

[0011] Further, when the spreading function mode of the bus panel is switched to the automatic mode, the spreading width and spreading density parameters required for spreading are input into the display. During the vehicle running process, the vehicle speed variable of the chassis is collected. Through the formula "spreading amount = spreading width × spreading density × vehicle speed", the upper-mounted controller calculates and outputs a PWM signal through the program to control the opening of the hydraulic proportional valve and adjust the rotation speed of the hydraulic motor. Through PID instruction correction, the precise control of the spreading amount is realized.

[0012] Further, in terms of reverse self-lifting, during the process of reversing in contact with the ground, the upper-mounted controller will collect the reverse signal of the chassis at this time, and all the execution mechanisms will be automatically lifted, reducing manual operation. More importantly, it reduces the occurrence of different degrees of damage to the machine during the reversing process, adding a touch of humanity.

[0013] Further, in terms of the spraying system, the upper-mounted controller will collect the water level sensor information in real time to protect the spraying system. When the water level is too low, first, the upper-mounted controller will send instructions to the voice alarm device and the display to prompt the voice alarm of low water level and the dynamic alarm of the interface. Then, the waterway work of the spraying device will be cut off until the fault is eliminated, and the waterway system can work normally, which well protects the pump from damage caused by water shortage and improves the service life of the pump.

[0014] The beneficial effects of the present utility model are as follows: Through the intelligent electronic control system of the multifunctional snow removal vehicle, the vehicle can perform integrated operations. All functions such as front snow sweeping, middle ice breaking, rear snow sweeping, intelligent spreading, and intelligent spraying can be completed in the cab, effectively improving the operation efficiency and quality. It gets rid of the traditional switch control method, adds intelligent control elements to the actions of the machines, improves the operation quality and efficiency, the convenience of operation, and the humanized color of human-machine interaction.

The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0018] As Figure 1 shown, an intelligent electronic control system for a multifunctional snow removal vehicle includes: a human-machine display, a bus panel, a voice alarm device, a water level sensor, an upper-mounted controller, a chassis controller, and an actuator. The human-machine display, the bus panel, the voice alarm device, the upper-mounted controller, and the chassis controller perform real-time communication via a bus. The water level sensor is connected to the input port of the upper-mounted controller, and the output end of the upper-mounted controller is connected to the actuator for controlling the operation of the actuator. The bus is a CANBUS bus.

[0019] The upper controller, display, bus panel, voice alarm device, sensors, etc. all adopt well-known brands, featuring high precision, strong anti-interference ability, high protection level, and CAN bus as the expansion interface, which is convenient for communication with other devices and vehicle debugging, with a certain degree of reliability. The core control component is responsible for collecting signals provided by external sensors and data required by the display, and is also responsible for logical operations in software, making judgments and outputs. Therefore, the vehicle-mounted upper controller with a working temperature range of -40~85°C, good anti-electromagnetic interference performance, and a protection level above IP67 should be adopted. The model of the upper controller is KM4658B, which has 3 CAN bus interfaces, supports free protocols, 58 input IO resources, and 46 output IO resources; the model of the display is HC-SUK8070-interface, a 7-inch industrial resistive touch screen, with RS485 / RS232 / CAN interfaces, and the CAN interface complies with the CAN2.0B standard; the model of the voice alarm device is BJ5210, integrating voice warnings, with updatable content, and using CAN bus communication, ensuring high quality.

[0020] The water level sensor provides digital signals for the upper controller to protect the sprinkler system pump in real time; through logical analysis and operation, the upper controller outputs digital signals and PWM signals to drive the front snow brush solenoid valve, rear snow brush solenoid valve, spreader solenoid valve (PWM output is used to drive the electro-hydraulic proportional valve, with a pulse width output of 0~100% and a valve body current value of 0~600MA), sprinkler device solenoid valve, and auxiliary devices, etc.; the upper controller communicates with the chassis controller to collect vehicle speed variable parameters, and through program function calculation and PID correction, the intelligent spreading function of the spreader can be realized.

[0021] The actuators include: front snow brush solenoid valve, middle ice-breaking roller solenoid valve, rear snow brush solenoid valve, spreader control mechanism, sprinkler device solenoid valve, and auxiliary devices. The front snow brush solenoid valve, middle ice-breaking roller solenoid valve, rear snow brush solenoid valve, spreader control mechanism, sprinkler device solenoid valve, and auxiliary devices are all connected to the output terminal of the upper controller.

[0022] The front snow brush solenoid valve is used to control the operation of the front snow brush, the middle ice-breaking roller solenoid valve is used to control the operation of the middle ice-breaking roller, the rear snow brush solenoid valve is used to control the operation of the rear snow brush, the spreader control mechanism is used to control the operation of the spreading device, and the sprinkler device solenoid valve is used to control the operation of the sprinkler device.

[0023] The spreader control mechanism includes: a spreader solenoid valve for controlling the spreader, a spreader lighting device for lighting, an electric push rod for adjusting the spreader operation, and a radiator for spreader heat dissipation.

[0024] The auxiliary device includes: a conversion module, a vehicle-mounted lighting device, and a combined fan. The conversion module is connected to the output end of the upper-mounted controller, and the vehicle-mounted lighting device and the combined fan are connected to the output end of the conversion module.

[0025] A CANBUS communication network is established among the upper-mounted controller, the bus panel, the voice alarm device, the human-machine display, and the chassis controller. With the upper-mounted controller as the core, the bus panel sends control instructions to the upper-mounted controller. The upper-mounted controller outputs execution commands through the IO domain after logical analysis and operation. At the same time, the controller sends them to the human-machine display and the voice alarm device through the bus to display the working state of the device. The voice alarm device gives prompts in the form of voice for abnormal signals. During the intelligent spreading process, the upper-mounted controller will collect the vehicle speed message information of the chassis controller to provide a data operation basis for the next high-precision spreading, so as to ensure that the unit spreading amount does not change with the vehicle speed.

[0026] When the bus panel switches to the manual mode, the actuator is controlled to work through the upper-mounted controller. Through the point-to-point output mode, corresponding action controls can be performed on the front snow brush, the middle ice-breaking roller, the rear snow brush, the spreading device, and the spraying device. The bus panel realizes multifunctional buttons through program definition. A total of 3 groups of multifunctional buttons are defined, and one button can complete the control, namely the work, floating, and stop of the front snow brush, the work, floating, and stop of the middle ice-breaking roller, and the work, floating, and stop of the rear snow brush, which provides excellent convenience in operation.

[0027] When the spreading function mode of the bus panel is switched to the automatic mode, the spreading width and spreading density parameters required for spreading are input into the display. During the vehicle running process, the vehicle speed variable of the chassis is collected. Through the formula "spreading amount = spreading width × spreading density × vehicle speed", the upper-mounted controller calculates and outputs a PWM signal through the program to control the opening of the hydraulic proportional valve and adjust the rotation speed of the hydraulic motor. Through PID instruction correction, the precise control of the spreading amount is realized.

[0028] In terms of reverse self-lifting, during the reverse process in contact with the ground, the upper-mounted controller will collect the reverse signal of the chassis at this time, and all actuators will be automatically lifted, reducing manual operation. More importantly, it reduces the occurrence of different degrees of damage to the machine during the reverse process, adding a more user-friendly feature.

[0029] In terms of the spraying system, the upper-mounted controller will collect the water level sensor information in real time to protect the spraying system. When the water level is too low, first, the upper-mounted controller will send instructions to the voice alarm device and the display to prompt the voice alarm of low water level and the dynamic alarm of the interface. Then, the water circuit of the spraying device will be cut off until the fault is eliminated, and the water circuit system can work normally, which well protects the pump from damage caused by water shortage and improves the service life of the pump.
