[0002] Traditional fuel tractor PTO is powered by a diesel engine, and its output speed cannot be adjusted arbitrarily, it can only be fixed at two to three rated speeds, and the matching agricultural implements need to be equipped with a suitable reduction mechanism to be able to use normally
In an electric tractor, the PTO output can be completed by a separate motor, and its speed regulation becomes possible. If it is arranged like a traditional tractor, that is, the driving motor is connected to the PTO through a mechanical transmission, the motor power demand is large, and the overall system mechanical structure is more complicated. , did not take advantage of the electric drive

Embodiment
[0024] Dual-motor electric tractor PTO control system, including input devices, non-driven wheel speed sensors (used to detect the speed of non-driven wheels), master controller, D / A conversion circuit and PTO motor controller;
[0025] Input device: In the working condition of the tractor, there are often cases where the PTO motor is required to provide rated speed output and to control the sowing distance (the speed of the PTO motor needs to be controlled according to the speed of the tractor). Therefore, in this embodiment The control information input to the general controller through the input device includes controlling the follow-up and rated rotation of the PTO motor; among them, the input device adopts digital key input; because there are many keys required, the matrix must be used to occupy as few controller ports as possible However, if you connect in a one-to-one way, you still need more port resources; this solution adopts a matrix connection button circuit with dy...

The invention relates to a dual-motor electric tractor PTO control system. The dual-motor electric tractor PTO control system mainly comprises an input device, a non-driving wheel rotating speed sensor, a total controller, a D / A switching circuit and a PTO motor controller. The control system has two main functions of being used for achieving the aims that the rotating speed of the dual-motor electric tractor PTO synchronously follows the driving speed of a tractor, and a reasonable and reliable accurate interval control method and control system is provided for sowing operation, pesticide spreading operation and the like of the electric tractor and being used for achieving the aim that the dual-motor electric tractor PTO outputs and matches different agricultural implements at any certainrotating speed in the adjustable range.
Description
technical field [0001] The invention relates to the field of tractor control, in particular to a dual-motor electric tractor PTO control system. Background technique [0002] Traditional fuel tractor PTO is powered by a diesel engine, and its output speed cannot be adjusted at will. It can only be fixed at two to three rated speeds. The matching agricultural implements need to be equipped with a suitable reduction mechanism to be able to use normally. In an electric tractor, the PTO output can be completed by a separate motor, and its speed regulation becomes possible. If it is arranged like a traditional tractor, that is, the driving motor is connected to the PTO through a mechanical transmission, the motor power demand is large, and the overall system mechanical structure is more complicated. , did not take advantage of the electric drive. Therefore, electric tractors are suitable to use a separate PTO motor, and it is very meaningful to develop a corresponding control sy...
