Man-machine interface 13 comprises LED dot matrix screen 131, voice module 132 and clock display module 133, and the parking information of car owner all shows in man-machine interface 13, comprises the car information, consumption information, down time etc. of car owner, can also pass through voice reminder.
Micro controller MCU1 is parking lot slave computer master control borad acp chip, and the RS485 circuit 4 of access band lightning protection effect between micro controller MCU1 and host computer, prevents from being struck by lightning in PC control signal transmits, affect the operational management of whole control system.Micro controller MCU1 adopts serial ports and LED dot matrix screen 131, language module, clock display module 133 and card machine 12.Micro controller MCU1 and LED dot matrix screen 131, voice module 132, clock display module 133 and card machine 12 are unidirectional data transmission, namely can only send signal control LED dot matrix screen 131, voice module 132, clock display module 133 and card machine 12 by micro controller MCU1 and work; Be bi-directional transfer of data between micro controller MCU1 and host computer, often exchange different information.Micro controller MCU1 and be unidirectional data transmission between LED dot matrix screen 131, voice module 132, clock display module 133 and card machine 12, between them, Serial Port Transmission data are completely can time-sharing multiplex, host-host protocol needs specification good, adopt consolidation form, ensure after micro controller MCU1 sends information, LED dot matrix screen 131, voice module 132, clock display module 133 and card machine 12 all can receive orders timely and accurately and correctly be resolved, and give respective response.
Micro controller MCU1 adopts P0 parallel port and function dial-up to arrange 5, plane No. dial-up arranges 6, peripheral state detects 7, storer 8, duty indicate 9, gate drives 10 and card reading module 11 etc. to be connected.Function dial-up arranges 5, plane No. dial-up arranges 6, peripheral state detects 7, duty instruction 9 and gate drive 10 for unidirectional information transmission; And storer 8 and card reading module 11 are two-way exchange data.Function dial-up arranges 5, plane No. dial-up arranges 6, peripheral state detects 7 unidirectional breaths of delivering a letter to micro controller MCU1, and the unidirectional photos and sending messages of micro controller MCU1 drives 10 to duty instruction 9 and gate; Micro controller MCU1 arranges 5 by code translator timesharing gating function dial-up, plane No. dial-up arranges 6, peripheral state detects 7, storer 8, duty instruction 9, gate drive 10 and card reading module 11.Peripheral state detects 7 for detecting card taking key-press status, vehicle detection state, card machine state and banister state; Native system adopts flash memory as storer 8, and benefit is that system can not the loss of data because of power-off, and data are continuously effective all the year round.
In this preferred embodiment, micro controller MCU1 adopts 8051 serial IC, and it is strong that it has anti-electromagnetic interference capability, cost performance high feature.These micro controller MCU1 are 8051 single-chip microcomputer latest fashions, and inside has abundant RAM resource, built-in dog, Double Data pointer and a large amount of appearance and stores ROM.Concrete model can select 89C58RD+ or 90C58RD+, but preferably selects 11 series, and as 11F32XE.11 series is operation clock, and master routine travelling speed is faster, and all kinds of external unit of system responses more promptly and accurately.
In this preferred embodiment, adopt flash memory as storer 8, the benefit of flash memory is that system can not the loss of data because of power-off, and data are continuously effective all the year round.In addition the storage space of flash memory, can preserve a large amount of data messages.Consider the characteristic of flash memory, the any data of single byte or whole sector can be read, but can only be whole sector operation stored in data, the data taking the preservation of large quantity space are needed to be applicable to very much being stored in herein in system, as user profile, vehicle discrepancy recorded information, period management and control information, time all kinds of, rent the expenses standard etc. of card.In addition, consider the same space of flash memory repeatedly erasable number of times only have 100,000 times, in the system of parking lot, information often changes, storage information still needs to adopt certain algorithm, extend flash memory tenure of use (in general, at least 10 years systematic economy life-spans), storing record in a flash memory needs to adopt Double Data pointer, roll mode is preserved, and avoids being kept at same place always.In addition frequent information of rewriting is needed to those, some small parameters of system need to preserve in addition, as record number, number of users etc., can be saved in the EEPROM of micro controller MCU1, certainly also there is a small amount of ram space in the clock chip had, also can be used for preserving this type of data.
Parking lot controller is all mounted in open air mostly, and there is minefield in the many places of China, and be easily struck by lightning at the consumer of minefield work, the setting for the lightning protection circuit playing step-down lightning protection effect is absolutely necessary.Therefore the lightning protection circuit accessed in the controls had accessed the first pressure limiting components and parts of pressure limiting effect before this between two connections, and the first pressure limiting components and parts carry out first time line-to-line correlation lightning protection process; Secondly, two connections have respectively accessed the second pressure limiting components and parts of pressure limiting effect, and the second pressure limiting components and parts carry out second time step-down lightning protection process over the ground; On two connections, respectively accessed the current limliting components and parts of metering function again, current limliting components and parts carry out third time current limliting lightning protection process; When signal passes to herein, each access clamper components and parts on two connections again, clamper components and parts carry out the 4th step-down lightning protection process; Signal passes to micro controller MCU1 through RS485 chip thus, and whole lightning protection circuit accesses the first pressure limiting components and parts, the second pressure limiting components and parts, current limliting components and parts and clamper components and parts successively.
As shown in Figure 3, in this preferred embodiment, lightning protection circuit adopts differential mode transmission data, and namely carry out by the voltage difference between two communication lines the number of delivering a letter, host computer sends down the number of delivering a letter to each controller, need to walk the pipeline under concrete floor, induced lightening is easily gone here and there on these signal wires.Be provided with lightning protection circuit in described RS485 circuit (4), this lightning protection circuit comprises signal first input end, signal second input end, the first lightning protection discharge tube, the second lightning protection discharge tube, the 3rd lightning protection discharge tube, the first resistance, the second resistance, the first Transient Suppression Diode, the second Transient Suppression Diode and RS485 chip.
