Embodiment
Below in conjunction with accompanying drawing, preferred implementation of the present utility model is described further:
With reference to shown in Figure 1, a kind of electronic control system of multi-leaf optical grating is disclosed.This control system is made up of with grating 4 PC 1, control device 2, motor 3.Wherein, PC 1 is a terminal device of realizing human-computer interaction interface and short range/Long-distance Control; Control device 2 one ends and 1 interactive connection of PC, the communication between realization and the PC 1, response is from the instruction or the control strategy of PC, and the other end then links to each other with a plurality of motors, realizes the driving simulating signal output to motor; Motor 3 is the direct parts that the position of grating 4 detected and regulated grating 4 Position And Velocities.
And for example shown in Figure 1, control device 2 has a main control unit 21, two or more from control module 22.Each is controlled 21 output pins with main control unit respectively from control module 22 and is connected to realize utilizing the communication between main control unit 21 realizations and the PC 1.As shown in Figure 2, in present embodiment, main control unit 21 and adopt ATmega162 chip, DSPIC30F2010 chip as its main control chip respectively from control module 22.Shown in Fig. 2 and 3, the ATmega162 chip has two serial ports (being pin 3 and 4,10 and 11), and wherein serial ports 1 (being pin 3 and 4) is connected with PC 1 by the level conversion of MAX3468 respectively, realizes carrying out communication with PC 1 with the RS485 communication modes; Serial ports 2 (being pin 10 and 11) then is connected with the RXD pin with TXD from the DSPIC30F2010 chip of control module 22 by a MAX3468, realizes main control unit 22 and a plurality of communications based on the RS485 agreement from control module.During work, main control unit receives from replying confirmation after the order of PC, on the one hand the order of receiving is discerned, the command frame that needs are transmitted adds each and sends in order from the control unit behind the address of control unit, on the other hand by itself regularly query strategy each status information from the control unit is monitored.Between PC 1 and the control device 2, main control unit 21 and from adopting the RS485 agreement to carry out communication between the control module 22 respectively, it is advantageous that, the interface signal level is low, do not allow the chip of rapid wear interface circuit, the data maximum transmission rate is 10Mbps, help improving the speed of response each other, noise immunity, communication distance is long etc.In order to satisfy main control unit 21 and the condition of work of control chip from control module 22,18 and 19 pins of ATmega162 chip connect one and have 11.0592 crystal oscillator with the needed frequency of the work of obtaining, 6 pins of DSPIC30F2010 chip adopt the clock frequency of 7.372MH as its clock frequency input, and other condition of power supply can be implemented with reference to the operation instruction of this chip.
With reference to figure 1, what be connected with the main control unit 21 of control device 2 has a plurality of (being 56 here) from control module 22.During concrete enforcement, can decide according to grating quantity and actual needs from the actual quantity of control module 22.Because main control unit 21 and the communications protocol that adopts RS485 from control module 22 can make from control element number maximum to reach 400 by changing the type of 485 chips.With reference to shown in Figure 3, the circuit of all control modules 22 is basic identical, because each has distributed address unique the system from control unit 22,22 process MAX3468 receive the order from main control unit 21 from the control unit, respectively to inquiring about the position of motor, state, and real time reaction is made in the order that requires motor movement etc., so the DSPIC30F2010 from control module 22 is controlled by adopting RS485 agreement and ATmega162 chip, can realize on the one hand in a large number from controlling the access of unit 22, save simultaneously the cost of main control unit again, guarantee communication efficiency each other.
With reference to figure 1 and Fig. 4, control device 2 also has electric-motor drive unit 23, and electric-motor drive unit 23 is realized being converted into the simulation control output that is fit to servomotor 3 from the digital control output of control module 23 between control module 23 and the motor 3.As shown in Figure 4, it is main chip for driving that electric-motor drive unit 23 adopts A3953SLB, from the microcontroller chip dsPIC30F2010 of control module 22 connect A3953SLB /BREAK, PHASE ,/three pins of ENABLE, to realize comprising the function of brake control, direction control, PWM control.Control constantly from 22 pairs of motors 3 of control module, microcontroller put dsPIC30F2010 give A3953SLB /BREAK and PHASE put high level respectively (just to be changeed, be low level during counter-rotating), pass through to regulate the speed control of the dutycycle realization of pwm pulse ripple simultaneously to servomotor.The coding that the scrambler of servomotor 3 inside returns is counted by the QEI interface; realize position feedback, and with analog feedback signal input to from the ADC analog-to-digital conversion module of the microcontroller chip dsPIC30F2010 of control module 22 with the monitoring that realizes stop position with the driven by servomotor overcurrent is protected.
Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
