Description
technical field:
the utility model relates to a kind of animal parasitic worm's ovum quantitative check counter.
background technology:
at present, parasitic ovum counting is general first takes stopgap measures this to carrying out sampling by inspection animal, and with microscopic examination after making sample, artificial counting, counter on the market generally selected by counter, and complex operation uses inconvenience.
summary of the invention:
the purpose of this utility model is to provide a kind of animal parasitic worm's ovum quantitative check counter.
above-mentioned object is realized by following technical scheme:
1. an animal parasitic worm's ovum quantitative check counter, its composition comprises: counter housing, it is characterized in that: one group of AT89S51 single-chip microcomputer is installed in described counter housing, described AT89S51 single-chip microcomputer respectively with reset circuit, clock circuit, key circuit, digital pipe display circuit is electrically connected, described counter housing is provided with one group of LED display, described LED display is connected with usb circuit, the P3.7 pin of described AT89S51 single-chip microcomputer connects a touch-switch, the P2.0-P2.7 of described AT89S51 single-chip microcomputer connects a common cathode charactron, described AT89S51 single-chip microcomputer P0.0-P0.7 connects a common cathode charactron.
according to above-mentioned animal parasitic worm's ovum quantitative check counter, it is characterized in that: the side in described counter housing is provided with battery case, USB interface, reset key, described housing upper surface has one group of tally function button.
beneficial effect:
the utility model connects a touch-switch at the P3.7 pin of AT89S51 single-chip microcomputer, as the button of manual count, a common cathode charactron is connect with the P2.0-P2.7 of single-chip microcomputer, as the units display of 00-99 counting, a common cathode charactron is connect, as the tens display of 00-99 counting with the P0.0-P0.7 of single-chip microcomputer.Numerical monitor is carried out in the loop using single-chip microcomputer to be formed, and improves the intuitive of counter, and be convenient to technician and observe, counter inside has battery, convenient with carry out parasitic ovum counting under various circumstances.
the utility model inside has LED display, by pre-edit, import by USB flash disk name or the code support technician differential count that computing machine directly inputs counted parasitic ovum, avoid and need handmarking and mark easily to lose or fuzzy shortcoming in the past.
the utility model is provided with a key and resets, and after completing counting, counting provides condition easily again next time.

embodiment:
embodiment 1:
a kind of animal parasitic worm's ovum quantitative check counter, its composition comprises: counter housing 1, one group of AT89S51 single-chip microcomputer 2 is installed in described counter housing, described AT89S51 single-chip microcomputer respectively with reset circuit 10, clock circuit 11, key circuit 12, digital pipe display circuit 13 is electrically connected, described counter housing is provided with one group of LED display 5, described LED display is connected with usb circuit 6, the P3.7 pin of described AT89S51 single-chip microcomputer connects each touch-switch, the P2.0-P2.7 of described AT89S51 single-chip microcomputer connects a common cathode charactron 4, described AT89S51 single-chip microcomputer P0.0-P0.7 connects a common cathode charactron.
embodiment 2:
animal parasitic worm's ovum quantitative check counter according to embodiment 1, the side in described counter housing is provided with battery case 9, USB interface, reset key 7, and described housing upper surface has one group of tally function button 8.
embodiment 3:
clock circuit according to embodiment 1 or 2 is not very high system for time requirement, as long as carry out design by figure just can make the reliable starting of oscillation of system and stable operation.But due to the electric capacity in figure play a part system clock frequency fine setting and stable, therefore, selecting properly parameter (30+/-10PF) must be noted in the practical application of this Clock system, and ensure the symmetry of circuit, select ceramics or the mica capacitor of manufacturer production of an established trade mark, if possible, temperature coefficient is low as far as possible.
described reset circuit generally should have manual or upper reset circuit.The realization of reset circuit has two kinds of modes usually: i.e. special UP supervisory circuit and RC reset circuit.The former circuit realiration is simple, and cost is low, but reset reliability is relatively low; The latter's cost is higher, but reset reliability is high, and especially highly reliable repetition resets.Occasion that is high and that monitor supply voltage is required for reset, mostly adopts in this way.What the utility model adopted is RC reset mode.The essence of RC reset circuit is single order charge-discharge circuit.
described key circuit and digital pipe display circuit simply as shown in FIG., succinctly facilitate, select regular producer original paper during assembling.
