[0048] As shown in Figures 1 to 5 , the present application provides an electromechanical control system.

[0049] The electromechanical control system is applied to a new energy tractor, and comprises a low-voltage power supply module 1, a vehicle control module 2, a starting module 3, a high-voltage power supply module 4 and an electronic control module 5.

[0050] The low-voltage power supply module 1 is used to provide low-voltage power to the vehicle control module 2 and the equipment at the tractor cab end; the vehicle control module is used to control the tractor as a whole.

[0052] The high-voltage power supply module 4 is used to provide high-voltage power to the electronic control module 5; the electronic control module 5 is used to control the tractor for work and travel when the tractor is running.

[0053] It should be noted that, since the tractor is slow when performing work, using the fuel system as the power output of the tractor will cause waste of energy and pollution to the environment. The new energy tractor of the present application uses electric energy as the power output of the tractor, which does not produce exhaust emission, reduces the pollution to the environment, and since the control logic is relatively simple, the cost required for daily maintenance and maintenance is less

After all the motors inside the tractor start to run, the starting motor will stop working. It should be noted that the new energy tractor of the utility model adopts a motor, so that the energy conversion efficiency is higher, the cost is reduced, and the noise is reduced.

[0059] In an embodiment, as shown in Figure 2 As shown, the low-voltage power supply module 1 is also used for providing low-voltage electricity to the low-voltage control system. It should be understood that in the working process of the tractor, the low-voltage control system controls the working state of the pump, valve and other components in the hydraulic system by receiving instructions from the operating handle, pedal and other components. After processing these instructions, the system can realize accurate control of the hydraulic system pressure, flow and direction. By adjusting the opening degree and direction of the control valve, the system can realize accurate control of various functions of the tractor, such as gear shifting, steering, braking, etc.

[0062] The PTO control subunit 511 comprises: a PTO motor controller 511A and a PTO motor 511B connected with the PTO motor controller 511A; the PTO motor 511B is connected with a PTO shaft; the PTO motor controller 511A controls the PTO motor 511B to rotate forward or reversely, the PTO shaft rotates under the driving of the PTO motor 511B, thereby controlling the work equipment on the tractor to steer; the steering control comprises but is not limited to left steering control, right steering control, etc.; the PTO control subunit 511 is also provided with various control gears in advance, and the moving degree of the work equipment is different under different gears.

[0064] It should be understood that the above-mentioned control of the work equipment to move through the gear adjustment is an intelligent control. The PTO (Power Take-Off) shaft is an important part of the transmission system of the tractor, and is located at the end of the transmission system. The main function is to transmit the power provided by the PTO motor to the driving equipment. This transmission process can enable the tractor to drive the work equipment to perform various types of work. The hydraulic module is the hydraulic system on the tractor, which is used to convert the power provided by the hydraulic motor into hydraulic energy to control the work equipment to move up or down.

[0071] It should be understood that the main function of the gearbox controller is to receive various sensor signals from the tractor, such as the speed sensor, the walking motor speed sensor, the accelerator pedal position sensor, etc., and then calculate the best shifting time and shifting mode according to these signals and the preset shifting strategy, and finally realize the shifting operation by controlling the actuators inside the gearbox (such as the shifting solenoid valve, the clutch solenoid valve, etc.). The gearbox changes the transmission ratio by different gear combinations, and then adjusts the tractive force and the speed of the tractor to meet the different needs of the tractor for driving wheel tractive force and speed under different driving conditions such as starting, accelerating, driving and overcoming road obstacles. For example, at low gear, the transmission ratio is large, and the tractor can obtain a larger tractive force; at high gear, the transmission ratio is small, and the tractor can obtain a higher driving speed. The steering motor controller controls the speed, direction and torque of the steering motor by adjusting the size of the direct current output by the steering motor. The steering motor is an important part of the tractor steering system, and its main function is to convert the force or torque applied by the driver through the steering wheel into steering action of the wheels. The walking motor, as a kind of traction motor, is an electric motor that drives the tractor to walk. It can convert electrical energy into mechanical energy to push the vehicle forward or backward.

[0078] It should be noted that in this embodiment, only the process of the power distribution unit 6 distributing power to the main control structure in the electric control module 5 is described. For other control structures in the electric control module, the power distribution unit will also distribute power according to the required power.

[0079] It should be further noted that when the horsepower segment of the tractor changes, the power required by each unit in the electric control module 5 will change, and the power output by the high-voltage power supply module 4 will also change accordingly.
