Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, open type magnetic switch triggering system, this system comprises stepping motor 1, drive circuit module 2, power circuit module 3 and unsettled magnet ring 4 above hopper one side, magnet ring 4 is connected with magnetic-control switch of dry-reed 5, and trigger magnetic-control switch of dry-reed 5 to 6 one signals of signal isolation circuit module by magnet ring 4, transfer the signal to the single chip circuit module 7 by signal isolation circuit module 6, send pulse signal to drive circuit module 2 by single chip circuit module 7, carry out Driving Stepping Motor 1 by drive circuit module 2 and rotate.Single chip circuit module 7 is powered in real time by power circuit module 3.
As shown in Figure 2, the utility model is when magnet ring 4 is during near magnetic-control switch of dry-reed 5, make switch closure, now the optocoupler conducting in signal isolation circuit module 6 is luminous, VO output low level, make single chip circuit module 7 send pulse signal to drive circuit module 2, Driving Stepping Motor 1 rotates, and the number of turns and the burst length of rotation are directly proportional.
As shown in Figure 3, when magnet ring 4 is during away from magnetic-control switch of dry-reed 5, switch opens, the optocoupler in signal isolation circuit module 6 is not luminous, and VO exports high level, makes single chip circuit module 7 output low levels to drive circuit module 2, and now stepping motor 1 does not respond.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
