Detailed description of the invention
The deviation correction control system of a kind of brshless DC motor based on CAN as shown in Figure 1, including the sensor 1 for detecting material shifted signal, after material shifted signal for being received the output of described sensor 1 by CAN module 2 is processed and driven the controller 3 of brshless DC motor 5 by brushless motor driver module 4, described brshless DC motor 5 and the driver 6 for eliminating material deviation connect, described controller 3 enables brushless motor driver module 4 by the state of Hall switch 7, described Hall switch 7 connects with brshless DC motor 5, described Hall switch 7 connects with the input of controller 3, the input of described controller 3 is connected to the limit switch 11 for being triggered and then make brshless DC motor 5 shut down when described driver 6 exceedes range, the input of described controller 3 is connected to for gathering the current signal flowing through described brushless motor driver module 4 current sampling circuit 10 converting voltage signal to, the speed of brshless DC motor 5 is carried out PID adjustment and brshless DC motor 5 is realized overcurrent protection by the sampled voltage signal that described controller 3 is exported by current sampling circuit 10, the outfan of described controller 3 is connected to the sound and light alarm module 8 for sending sound and light alarm signal, described sensor 1 and controller 3 are connected to communication transfer interface module 13 each through described CAN module 2, described communication transfer interface module 13 connects with host computer 14.
As it is shown in figure 1, the outfan of described controller 3 is connected to the display 12 of the side-play amount for showing material. The input of described controller 3 is connected to the key-press module 9 for arranging deviation-rectifying system parameter.
In the present embodiment, described display 12 is liquid crystal display. Described controller 3 adopts dsPIC30F5016 controller.
In the present embodiment, if material side-play amount being passed to controller 3 when sensor 1 detects material shifted signal to controller 3 under automatic deviation correction pattern by CAN, controller 3 drives brshless DC motor 5, brshless DC motor 5 to drive corresponding driver 6 finally to make material not have deviation as much as possible by brushless motor driver module 4 after material shifted signal being processed.

Adjustment support is finely tuned in 1/2 position. The mobile support that regulates makes test point be positioned at sensor 1 graticule position, and locking regulates support. Choose driver 6 direction. Reference sensor 1 adjustment method has debugged sensor 1. By automatic keying, now material detects controlled point by automatically moving to sensor 1, if material reversely mobile deviation sensor 1, illustrates that brshless DC motor 5 set direction is incorrect, can click the positive and negative button of controller 3 and be revised. By left and right press key, artificially making material skew so, viewing system can correct material position automatically to test point. Open host work, according to material and to the requirement correcting precision, regulate sensitivity. Pull the position of some coiled strips, vibrate back and forth if there is driver 6, the sensitivity of controller 3 can be reduced, then can improve sensitivity when control accuracy is poor. By host computer 14, controller 3 and sensor 1, mode of operation can be arbitrarily set, as want to make the words that system is in automatic mode have only to operate on host computer 14 by host computer 14, as want to make driver 6 return to time middle button that center mode has only to click on sensor 1 by sensor 1 at the scene. In addition can pass through host computer 14, controller 3 and sensor 1 and the relevant parameter of deviation-rectifying system is set, the correction precision of all right real-time Simulation display deviation-rectifying system of host computer 14.
The above; it it is only presently preferred embodiments of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation above example made according to the technology of the present invention essence, all still fall within the protection domain of technical solution of the present invention.
