Sensor (501-1,501-2,501-3,501-4) and the first close close 312 signal of switch of switch 311, second It is input to single-chip microcontroller U4 input port D0-D5, alarm signal, stepper drive pulse signal, step are exported after single-chip microcontroller U4 processing Into positive/negative rotaring signal, CRANK PULSES EN, stepper motor drive module MD1 is allowed to be Two-level ensemble module, inside has been integrated with drive The required circuit that dynamic stepper motor 303 operates；It only needs input power, rotation direction, allow to operate EN and driving pulse Operate stepper motor 303 accordingly according to the signal of input, the operating of pulse rate height is fast, and the low operating of pulse rate is slow.

Single-chip microcontroller U4 control process can be as follows: after conveyer belt starts running, single-chip microcontroller obtain it is electric bring into operation, first by position The fan-in mouth state D7D6D5D4D3D2D1D0 for setting sensor and limit switch is read into memory B0, B0 with a byte High-low-position it is corresponding with input port D, wherein B0.0 respective sensor 501-1, B0.1 respective sensor 501-2, B0.2 Respective sensor 501-3, B0.3 respective sensor 501-4, B0.4 corresponding first connects close to switch 311, B0.5 corresponding second Nearly switch 312.B0.6, B0.7 are spare bits.Program designs for finite state, and 8 bit combinations of B0 share 256 kinds of states, corresponding Decimal number be 0-255.

B0=0(Binary Zero 0000000), B0=16(Binary Zero 0010000), B0=32(Binary Zero 0100000) 3 When kind of state, limit switch most one are in action state, and limit switch is without exception, position sensor without input signal, Conveyer belt does not run side, and execute identical program processing step: stepper motor does not need to operate, alarm that may be present before releasing Enter detection circulation next time afterwards；

B0=2(Binary Zero 0000010), B0=34(Binary Zero 0100010) when, sensor 501-2 movement, explanation Conveyer belt slightly runs side to the side sensor 501-2, and first is not operating close to switch 311, and threaded block 316 should be approached to first and be opened It is mobile to close 311 end low speed, allows to operate EN set, the positive/negative port reset that turns makes step actuator be placed in inverted status, sends out one A low speed pulse, stepper motor turn to move a step, alarm that may be present before releasing, into detection circulation next time；

B0=4(Binary Zero 0000100), B0=20(Binary Zero 0010100) when, sensor 501-3 movement, explanation Conveyer belt slightly runs side to the side sensor 501-3, and second is not operating close to switch 312, and threaded block 316 should be approached to second and be opened It is mobile to close 312 end low speed, allows to operate EN set, it is positive/negative to turn port set step actuator is made to be placed in rotating forward state, send out one A low speed pulse, stepper motor turn to move a step, alarm that may be present before releasing, into detection circulation next time；

B0=3(Binary Zero 0000011), B0=35(Binary Zero 0100011) when, sensor 501-2, sensor 501-1 is acted, and illustrates that conveyer belt is more to sensor 501-2 race side, first is not operating close to switch 311, screw thread Block 316 should be fast moved to first close to 311 end of switch, allow to operate EN set, the positive/negative port reset that turns makes step actuator It is placed in inverted status, sends out a high-speed pulse, stepper motor turns to move a step, alarm that may be present before releasing, under One-time detection circulation；

B0=12(Binary Zero 0001100), B0=28(Binary Zero 0011100) when, sensor 501-3, sensor 501-4 is acted, and illustrates that conveyer belt is more to sensor 501-3 race side, second is not operating close to switch 312, screw thread Block 316 should be fast moved to second close to 312 end of switch, allow operating EN set, positive/negative to turn port set and make step actuator It is placed in rotating forward state, sends out a high-speed pulse, stepper motor turns to move a step, alarm that may be present before releasing, under One-time detection circulation；

When the other states of B0=, it is abnormal to illustrate that sensor and limit switch value occur, it may occur however that sensor degradation passes Sensor malposition, limit switch damage, conveyer belt pine or belt pulley for feeding foil excessively it is not parallel it is more serious cause to run side have exceeded and watch The failures such as the limit of power of compensation are taken, EN is resetted and stepper motor is forbidden to operate, while set alarm message reminding staff examines It looks into.

The generation of stepper drive pulse uses Program time delay, when needing to generate driving pulse, first by the set of pulse port, Then starting the delay of high level section to wait, delay time arrives, by pulse port reset, continue the delay of pulses low section, A drive pulse signal is generated, each input detection cycle can be produced when the value of B0 is 2,34,4,20,3,35,12,28 A raw stepper motor driving pulse, stepper motor 303 turn to move a step to corresponding direction, and the step-length of stepper motor is only set with it In respect of pass, rotating total amount, only width related with driving pulse number and driving pulse is unrelated, pulse low and high level delay time State determining time much larger than B0, delay time is shorter, and pulse width is narrower, and output pulse number is got in the unit time More, the rotation of stepper motor 303 is also faster.

Above-mentioned control process those skilled in the art can be obtained according to the connection relationship of structure and the function of realization, can also It as long as can reach corresponding effect can belong to this field routine techniques, and is not the utility model using other control flows Problem to be solved；The purpose of the present utility model is the powerup issue for solving Servocontrol device.
