Preferably, said controller is a singlechip chip.
Preferably, said controller also links to each other with ISP circuit, keyboard.
Preferably, said display device is six positive high-power charactrons altogether.
Preferably, said display device driving circuit comprises position choosing mouthful driving circuit and section choosing mouthful driving circuit two parts.
Preferably, institute's rheme choosing mouthful driving circuit mainly is made up of a NPN type triode and a positive-negative-positive triode, and a said section choosing mouthful driving circuit is made up of reverse drive chip and current-limiting resistance.
Technique scheme has following beneficial effect: this scheme detects parking stall parking situation through photoelectric sensor when system works, through parallel-to-serial converter information transmission is arrived controller; Controller shows Parking Fee through the work of driving circuit control display device when having vehicle to leave on the parking stall, otherwise the demonstration time; Keyboard is used to be provided with systematic parameter, and the ISP interface circuit is used for the online updating program.This system has simplicity of design, easy to use, cost performance advantages of higher.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of instructions, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.

Fig. 3 is the utility model embodiment charactron driving circuit figure.
Fig. 4 is the utility model embodiment parking space information processing flow chart.
Embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
As shown in Figure 1, a kind of parking stall of the utility model time counting toll collection system comprises: 1 controller, 2 photoelectric sensors, 3 parallel-to-serial converters, 4 display devices, 5 driving circuits, 6ISP circuit, 7 keyboards.Said photoelectric sensor links to each other with controller through parallel-to-serial converter; Said controller links to each other with display device through driving circuit, and said controller also links to each other with ISP circuit, keyboard.Detect parking stall parking situation through photoelectric sensor during system works, information transmission is arrived controller through parallel-to-serial converter; Controller shows Parking Fee through the work of driving circuit control display device when having vehicle to leave on the parking stall, otherwise the demonstration time; Keyboard is used to be provided with systematic parameter, and the ISP circuit is used for the online updating program.
As shown in Figure 2, parking stall time counting toll collection system parallel-to-serial converter is realized through cascade system by the multi-disc and the conversion chip 74HC165 that goes here and there.The single-chip processor i/o resource is very limited, and the parking stall parking information that is detected by photoelectric sensor needs serial input single-chip microcomputer; Because it is bigger that parking space information quantity will be gathered by system, single and string conversion chip can't meet the demands, so a plurality of and string conversion chip need connect through the mode of cascade.Concrete grammar is the SI signal end that the SO signal end of every 74HC165 chip is linked into next piece 74HC165 chip, and first 74HC165 chip SI signal end is idle, and last piece 74HC165 chip SO signal end connects the MCU_QH signal end of single-chip microcomputer.All chip I NH signal end ground connection, the CLK signal end connects single-chip microcomputer MCU_CLK signal end, and the SH/LD signal end connects single-chip microcomputer MCU_SHL signal end.
As shown in Figure 3, the display device of parking stall time counting toll collection system is six high-power positive charactrons altogether, its driving circuit section of being divided into choosing mouthful driving circuit and position choosing mouthful driving circuit two parts.The driving circuit of each mainly is made up of a NPN type triode Q1 and a positive-negative-positive triode Q2 in the position choosing mouthful driving circuit; The base stage of Q1 links to each other with the general purpose I/O of single-chip microcomputer; Collector connects direct supply through resistance R 2 again through the base stage that resistance R 1 meets Q2, the Q1 grounded emitter.The emitter of Q2 connects direct supply, and collector connects the position choosing end of charactron.A section choosing mouthful driving circuit mainly is made up of reverse drive chip ULN2803 and current-limiting resistance; The section route selection of single-chip microcomputer meets the input end 1B～8B of reverse drive chip, and chip for driving output terminal 1C～8C connects the section choosing mouth of charactron through current limliting exclusion RP1.The mode that shows control employing scan round is carried out, and promptly lights one digit number sign indicating number pipe one by one, and switches at a high speed, because the vision of human eye stops characteristic, it is looked seem a plurality of charactrons steady display simultaneously.
The parking stall time counting toll collection system realizes that major function has automatic detection parking stall parking information, judges the parking stall state, calculates the parking stall Parking Fee, leaves the parking stall as vehicle and shows corresponding Parking Fee, shows the current time when idle.System program is mainly divided two ones of master routine and interrupt routines.Master routine comprises system initialization, detects the parking stall parking information, judges the parking stall state, update displayed formation, subroutines such as button processing; Interrupt routine is respectively timer T0 interrupt service routine and timer T1 interrupt service routine; Wherein the T0 interrupt service routine is responsible for system time control; The T1 interrupt service routine; Confirm displaying contents according to current parking stall state,, otherwise show the current time if having vehicle to leave the parking stall then show parking stall number and Parking Fee.
The parking stall state is divided into four kinds of situation i.e. " parking stall does not have parking always ", " parking stall parks cars always ", " vehicle leaves the parking stall ", " vehicle entering parking stall ".Parking stall state determining program function is to confirm that a certain parking stall is in any in four kinds of states, and carries out handled, and Fig. 4 is a parking stall state decision flow chart.Can be known that by figure determination methods is for read each parking stall parking information successively, when there is parking on a certain parking stall, if previous moment has had vehicle parking, then this moment, the parking stall should be " parking stall parks cars always " state, and this need not anyly be handled; Otherwise this moment, the parking stall was in " vehicle entering parking stall ", then should carry out handled, mainly was that the initial moment of stopping is carried out record.When a certain parking stall does not have vehicle parking, if previous moment has vehicle parking, then this moment, the parking stall should be " vehicle leaves the parking stall " state, should accomplish record car item this moment, the store car departure time, calculated Parking Fee, operations such as mark parking stall state; Otherwise this moment, the parking stall was in " parking stall does not have parkings always ", and then this need not any processing, so back and forth states judgements and disposing up to all parking stalls.
More than a kind of parking stall time counting toll collection system that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
