Abstract
The automatic timing fee collector for computer is composed of photoelectric converter, CPU, latch, program memory and display circuit. The utility model discloses simple structure, the dependable performance, the cost is low, convenient operation, and degree of automation is high, is suitable for as the use of various charging places of charging according to time.
Description
The utility model relates to a kind of computer self-clocking rater.
Continuous progress along with society, people's living standard is more and more higher, the enthusiasm that business hours is participated in various physical trainings grows to even greater heights, thereby, the various physical culture places that open to the public are also more and more, as the tennis court, the football field, blue court, court or the like, the general employing of its charge of these physical culture places is metered, at present, the self-clocking Fare Collection System that adopt in above-mentioned place is because of complex structure, cost is high and be very limited in actual applications, thereby, design a kind of simple in structure, dependable performance, cost is low, and easy to operate self-clocking rater does not have the vast market prospect that congealed.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple and reasonable, and is easy to operate, stable performance be suitable for the metered computer self-clocking rater in various physical culture place.
The utility model is to adopt following proposal to realize: it is by photoelectric switching circuit, central processing unit, latch, program storage, display circuit is formed, central processing unit calls corresponding program by latch and program storage and carries out computing, processing according to the information of photoelectric switching circuit input, to realize self-clocking charge and the purpose that shows.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the utility model electricity functional-block diagram.
Accompanying drawing 2 is the utility model electrical schematic diagram.
See accompanying drawing 1,2, the utility model is by photoelectric switching circuit 1, central processing unit 2, latch 3, program storage 4, display circuit 5, reference circuit 6, knob 7 is formed described photoelectric switching circuit 1, program storage 4, reference circuit 6, the output of knob 7 connects the input of central processing unit 2 respectively, and the output of central processing unit 2 connects display circuit 5 respectively, latch 3, the output of latch 3 connects the input of program storage 4, and photoelectric switching circuit 1 contains device D1-D3 by the photoelectricity coupling, and resistance R 2-R7 forms, and central processing unit 2 is made up of ic chip 1, latch 3 is made up of ic chip 2, program storage 4 is made up of ic chip 3, and display 5 is made up of the LED charactron, and reference circuit 6 is by crystal oscillator N, capacitor C 1, C2 forms, and knob 8 is made up of K switch.
Principle of work of the present utility model is sketched in following: when the utility model is used in various charges place, the personnel that enter this place are issued a card, this card is provided with two exhausting holes or blind hole, and through hole and blind hole are arranged according to certain rules, the holder only needs to be stuck in the groove of swiping the card on the utility model and brushes, the numbering that photoelectric switching circuit is about to this card converts electric signal to and inputs to central processing unit, central processing unit obtain exporting immediately behind this signal a signal through latch to program storage, calling one moves with this card corresponding programs control central processing unit, thereby, control the time that display shows this card numbering and stores this card input by central processing unit; When the holder leaves this physical culture place, only need card is brushed in the groove of swiping the card again, central processing unit will be controlled display at once and show the usefulness of should paying dues, simultaneously, available buttons 8 stirs the displaying contents of display successively, knowing holder's entry time, post-set time, consumption price and should hand over data such as total charge.
The utility model is owing to adopt the opto-electronic conversion mode to come the readable ard sheet, thereby simplified this machine structure greatly, and dependable performance, cost is low, easy to operate, therefore, the intensity of workers that alleviates various places by time charge there is significant effect, and can carries out network management with system microcomputer easily.
In sum, the utility model is simple in structure, dependable performance, and cost is low, and is easy to operate, and the automaticity height is suitable for using as various charge places charged according to time.
