Description of drawings
Fig. 1 is the composition block diagram of the utility model specific embodiment.
The specific embodiment
A kind of triroller gate as shown in Figure 1, comprises CPU1, feedback sense circuit 2, motor-drive circuit 3, motor 4 and the restrictor bar of being controlled by motor-driven.
The output of CPU1 is connected with the input of motor-drive circuit 3, and motor-drive circuit 3 receives the control signal of CPU with drive motors 4 runnings, rotates thereby drive restrictor bar.CUP1 adopts the ARM chip LPC2364 of NXP company, and motor-drive circuit 3 adopts the special chip IR2111 driving power pipe IRF540 that is provided with separately.
Restrictor bar position probing and restrictor bar speed detect by restrictor bar position detecting module and restrictor bar speed detection module and realize.The shared encoder of restrictor bar position detecting module and restrictor bar speed detection module, when the driven by motor restrictor bar rotated, the encoder output pulse signal was given CPU1, and the position and the speed that reach restrictor bar detect.
Restrictor bar Position Control process is: during device power, CPU1 rotates by drive circuit 3 drive motors 4, and after the drive restrictor bar rotates, thereby the encoder feedback P-pulse finds for CPU1 and the mechanical zero of definite restrictor bar.In the running, CPU1 detects the P-pulse number of encoder feedback, thereby judges the residing position of restrictor bar.When external world input command request restrictor bar rotates, during the P-pulse no show target location pulse that makes that encoder fed back, CPU1 outputs signal to drive circuit 3, and drive motors 4 rotates, and makes restrictor bar forward assigned address to.
The restrictor bar rate control process is: during motor rotation, before the output of CPU1 detection encoder, the time difference of latter two pulse, thereby calculate the actual speed of restrictor bar running, and the real-world operation velocity amplitude and the setting speed value of restrictor bar compared, if values for actual speed is faster than setting value, then output signal to drive circuit 3 control motors 4 and reduce the speed running, otherwise then control the motor running that builds up speed, make restrictor bar maintain the running of setting speed value by the rotating speed that changes motor 4, realize the closed-loop control of restrictor bar rotating speed, thereby solve the inharmonic problem of restrictor bar rotating speed that causes owing to the rotating disk degree of tightness of different gates is inconsistent.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
