Gate inhibition management system by brushing card in running
Technical field
The present invention relates to the wireless micro-power communication technology, particularly a kind of relevant with entrance guard management, remote-wireless identification and administrative skill.
Background technology
Up to the present, existing vehicle access control system except the same simple pulse signal controller of similar door remote control device has been used in indivedual places, generally all is after adopting parking, the current way to manage of closely swiping the card.The former is owing to security, and reliability is assurance not, thereby can't be used for the higher sub-district entrance guard management of management expectancy, said nothing of the management in charge garage, and the latter's shortcoming is:
1. because the general employed card of card-punching system all is passive, what adopt between card and the card reader all is the passive type communication mode, thereby the distance of swiping the card is very near, generally have only several centimetres to tens centimetres, thereby no matter burning sun rains, or hardships snow freezes, the car owner is before entering, must earlier car be rested in and leave on the comparatively accurate distance and position of machine for punching the card, turn down glass for vehicle window, swipe the card.Distance, you get " risking one's life " and extend your hand and go to swipe the card; Sometimes, you also must not open car door, get off and swipe the card.From near, then the car scratch might be hung very much and hinder.If the sub-district gate inhibition, such mode of swiping the card can make the sub-district feel to have a greatly reduced quality for people's warmth undoubtedly.
2. in addition, swipe the card, need many times, thereby, cause the vehicle jam toward the contact meeting in the rush hour of vehicle turnover owing to stop.
3. because existing gate inhibition's card-reading apparatus is all more expensive, existing gate inhibition's card generally all can only be specifically designed to the some specific gate inhibitions of turnover, and not only versatility is restricted, and does not have other more function.
Summary of the invention
The present invention is directed to existing access control system and not only manage trouble, waste time, efficient is low, and function singleness, with efficient garage management expectancy easily, and the gate inhibition's human-based management of existing sub-district requires incompatible, can not satisfy current " all-purpose card ", with the present situation of the multi-functional requirement of one card for multiple uses, provide a kind of fast efficient, multi-functional gate inhibition management system by brushing card in running.
The present invention adopts a kind of brand-new, two-way active wireless micropower communication system, replace closely card-punching system of existing passive type, use remote-wireless ID (identity number) card read write line to replace existing closely machine for punching the card, use the active radio ID (identity number) card to replace passive IC-card or magnetic card, by using button to send the mode of information, solved the problem in active battery card life-span, thereby it is simple, economical and realized the wireless identity card reader reliably, and the remote bi-directional digital communication between the wireless identity card has solved the problem that existing access control system must stop and swipe the card;
Because new read-write system is simple in structure, volume is little, and cost is low, can be installed in different places easily, and the numbering of card can accomplish that the world is unique, thereby can be easy to realize the function of " all-purpose card ";
In addition, because wireless identity card itself, no matter from information storage, encrypt and be provided with, the size of emissive power all can be carried out bigger adjustment according to actual needs, thereby expanded the usage space of card greatly, same card not only can be used as the wireless identity identification card, can also have the function of reporting to the police and locating;
The technical solution used in the present invention is:
Use the world today up-to-date, highly integrated micropower wireless receiving and dispatching machine chip, set up writing to each other between wireless identity card and the wireless identity card reader, not only separating component is few to make total system, compact conformation is simple, the reliability height, and greatly reduce the volume and the cost of read write line;
By adopting advanced direct sequence spectrum spread communication technology, the antijamming capability of system and the reliability of system works have been improved greatly, stability and security, the problem that is subjected to the big and poor work stability of disturbing effect of having avoided that general narrow band width wireless communication systems is difficult to avoid;
By adopting the mode of button work, make the only moment work when the turnover gate inhibition of system, all the other times all are in the state of outage, thereby system's power consumption is very low, battery life is very long, thereby has avoided the ubiquitous issue for battery life of general battery powered system;
By using SM card magnanimity internal memory to store all information of vehicle turnover, simultaneously, by adopting the mode of two SM cards (main card adds standby card), make system both can with computer interconnection work, also but off line is used separately, and when off line is used, can manage gate control system by far-end computer well;
When distinguishing the turnover gate inhibition the closely gate inhibition signal of button emission and enter the gate inhibition after, periodically regularly launch remote positioning signal, and the mode of long-time button emission alerting signal, can make same wireless identity jig that multiple function is arranged.
Concrete way is:
1. use identical wireless micro-power transceiver chip, make wireless identity card and wireless identity card reader respectively, can carry out radio communication between them;
2. the wireless identity card is carried by the car owner, it has a button, when pressing the button, the wireless identity card will use minimum emissive power, send self the identity code signal that is used to pass in and out the gate inhibition to read write line, after read write line is received the identity code signal that the wireless identity card sends, to beam back a receipt of receiving signal to the wireless identity card, comprising the time of receiving signal, simultaneously, the card number of wireless identity card can be shown on the display board of porch.After the wireless identity card is received the receipt signal, with starting the hummer of wireless identity card, make it send sound, or make LED flash, notify the holder, read write line has been received the identity code signal.
3. read write line can be equipped with the single-chip microcomputer of different processing functions and the internal memory of different capabilities according to the needs of practical application, is handled receiving from the signal of wireless identity card by wireless mode; Read write line generally is directly installed in the bearing of electric railing, and by RS232 or other interface mode, links with the electric railing controller; Turnover gate inhibition's read write line generally has different functions, and the read write line that enters the gate inhibition is mainly carried out identity verification and the function of the registration of crossing the threshold, and the gate inhibition's that goes out read write line is mainly carried out computational costs, stores functions such as the related data and the registration of going out; Read write line can be directly and the computer interconnection operation, but also off line independent operating; When read write line off line independent operating, single-chip microcomputer substituting for computer in the read write line is carried out function corresponding, simultaneously by the magnanimity internal memory SM card in the read write line, realize and management centre computer between information interchange.
4. after the read write line that enters the gate inhibition is received the ABC of request signal that the wireless identity card sends, will compare with stored identity code number in the read write line, and handle accordingly.For example, start railing, or tell car owner's relevant information etc.After vehicle enters the garage, presses the ground induction coil in railing the place ahead, the wireless identity card reader will think that vehicle has entered garage or sub-district, and wireless identity is sticked into the formal registration of row.
5. come the outlet gate inhibition when vehicle, when preparing to exit garage or sub-district, the car owner is the operation that repeats to enter, and different is, the read write line in exit, and the not information of reading of car owner's identity code just also comprises the temporal information that enters garage or sub-district; If the charge garage, read write line will utilize these information, and originally be stored in the relevant information in the read write line database, calculate the car owner should pay dues with and this card remaining sum of usefulness of having paid dues, and can on the digital display board in exit, show.
6. in the time need upgrading the information in the magnanimity SM card of read write line, or read write line need carry out data when exchanging with management centre computer, needs to use the specially-enabled card that is provided with to carry out, to guarantee fund security, guarantee user's rights and interests.
The invention has the beneficial effects as follows: compare the present invention with existing system
1. system architecture of the present invention is simple, and volume is little, and read write line can be directly installed in the existing electric railing bearing, and the wireless identity card has only general remote controller for vehicle size, can make bijou ornament, directly hangs on car owner's key-ring;
2. easy to use, need not stop and just can finish turnover gate inhibition inspection, registration, all working that charges and charge has been removed the trouble of stopping and swiping the card from, and has been improved the efficient of entrance guard management greatly.
3. safe and reliable, be the communication of direct sequence spread spectrum because the present invention adopts, and specific authorisation is provided with the data refresh mode of card, thereby, improved system's anti-jamming capacity, the reliability of work and the security of system;
4. system cost is low, the price of the card reader of existing card-punching system is generally all more than ten thousand yuan, if add the price of access control system, and the expense of ground construction, often will surpass 20,000 yuan, and the present invention has not only removed the trouble that existing gate control system must be stopped and be swiped the card from, has saved the time greatly, improved efficient, reduced the entrance guard management cost, and, can realize that also all-purpose card is used and a card is multi-functional; In addition, because system of the present invention only needs to install a very little read write line additional in mounted electric railing and just can work, thereby, it also can with existing other card-punching system compatibility of having installed, like this, the car owner both can use original row startup railing of closely swiping the card that sticks into, also can use new wireless identity card, no matter do not start railing at a distance, be to the sub-district gate inhibition with not stopping, the management in the garage of still charging, all bring great convenience, also bring more selection to the car owner.

Embodiment
Below with the example that is embodied as of automatic charge garage management system, to the present invention's further instruction in addition.
Automatic garage gate inhibition management system
1, brief introduction
Automatic garage gate inhibition management system is to be made of wireless identity card, wireless identity card reader, supervisory computer three parts.Read write line is installed in the gateway in garage, is used to receive the id information from the wireless identity card, and according to wireless identity card user type, it is registered and accounting processing; All vehicles are come in and gone out for future reference in the mass storage that situation (access time, remaining sum etc.) information all are stored in read write line and are disposed.
2, system constitutes
The part relevant with native system is the wireless identity card reader.This part system architecture such as accompanying drawing.
Wherein the RF module can adopt general Zigbee or other direct sequence spread spectrum micropower transceiver, is used for carrying out between read write line and the wireless identity card the mutual of data.Mass memory adopts jumbo SM storage card, and storage card adopts a main mode that is equipped with to dispose, and wherein main memory is as working storage.Standby as the exchanges data storer.The input/output signal of ground induction coil, topworks is switching value.LED shows the charactron mode that adopts.
3, principle of work
Be installed in the read write line at place, gateway, garage, behind the id information that receives from user's ID card, read write line is examined this identity, is then let pass if the user is eligible.The read write line that wherein enters the mouth is only carried out authentication, and the outlet read write line charges according to different user types, certain set Freight Basis when carrying out authentication and shows in real time.All vehicles are come in and gone out for future reference in the mass storage that situation (access time, remaining sum etc.) information all are stored in read write line and are disposed, and can above-mentioned information be dumped to supervisory computer by using slack storage card mode simultaneously.
4, systematic parameter is set and is adjusted
System has certain programmability to be fit to the needs of various different application occasions.Two kinds of the project that is provided with system clock that system is mainly concerned with and expenses standards.Be stability, the reliability of enhanced system work, system is provided with and adopts dedicated management that card is set, or multi-functional encryption is provided with the card mode and carries out.
4.1, clock setting and adjustment
For the consideration of chargeing, read write line should possess real-time clock (RTC) function and go out the detail time of warehouse-in to make things convenient for registration of vehicle.
In view of may not having direct communication link between the read write line of gateway, and adopt artificial key mode to be provided with and can bring on the one hand to be difficult for realizing that the mechanical part of having introduced synchronously, on the other hand between a plurality of read write lines is unfavorable for that equipment uses for a long time, the read write line clock employing management that therefore relates in this project is provided with the form of card and carries out.
For keeping the unanimity of clock, management is provided with card and also should has real-time clock.After managerial personnel start the clock setting function, card is set will downloads present clock to read write line by the RF channel, read write line is receiving the adjustment that begins to carry out self system clock after order is set, and the indication of available charactron is provided with and finishes.
4.2, expenses standard is set and adjust
Freight Basis has two kinds: a kind of is to charge according to the different periods; Another kind is to charge by year, month, day.Above-mentioned two kinds of charge methods are present in the read write line simultaneously, as for concrete which kind of charge method of carrying out decide according to the sign among the subscriber card ID.That considers this product can be universal, should be provided with period in the standard and unit interval rate.
5, Data Update, exchange and backup
System data exchange and backup can adopt dual mode to carry out.A kind of mode is carried out for adopting serial communication, and another kind of mode for employing SmartMedia (SM) card is carried out.
Under normal operation, the data in the read write line all are stored in the primary memory, can be undertaken by following step when needing more new data:
1, inserts the standby SM card that is used for exchanges data;
2, adopt management that card is set and order and password are set to the read write line transmission;
Read write line receive order is set after, at first detect the SM card and whether normally insert, if do not insert or mistake appears in card, then carry out miscue; If card inserts correct, then read the code data that carries in the SM card, and with this password with the data that ID (identity number) card sends over be set compare.If the two is identical, then allow to carry out Data Update.
Above-mentioned information is indicated by charactron, if correctly then charactron demonstration 1; If mistake is then all lighted charactron; Charactron flicker during data read and the backup; Charactron showed 0 after Data Update and backup were finished.
5.1, the order handled of Data Update
Illustrate:
* data recording is that unique index is distinguished with the ID users.
* Data Update is meant the data in the standby SM card is write primary memory.If contained this ID number in the primary memory, then the process of Data Update is to go to change data in the main memory with the data in the standby SM card; If there be not corresponding ID number in the primary memory, then the process of Data Update is that these data are write direct in the main memory.
At first carry out during exchanges data and upgrade operation, carry out backup then.The data that promptly read earlier in the shelf storage are upgraded the data in the primary memory, after finishing with data sync to standby SM card, for the maintainer with this data back supervisory computer.
5.2, order and password be set
For the rights and interests that ensure the user, guarantee fund security, this read write line adopts multiple safety practice when carrying out Data Update and backup.
At first, read write line can be carried out data renewal and backup operation after reception and authentication password.The reception of password and checking are avoided the duplicity password respectively simultaneously from two approach.Secondly, password can be preestablished by the managerial personnel that are authorized to, and can change.If adopt multi-functional encryption that card is set, then password is generation, once effective at random.The safety that is provided with for guaranteeing, password by supervisory computer generate at random, once effective.Code data is kept at the special purpose system card simultaneously and is used for the SM card of exchanges data, and concrete generating mode and memory location are determined by supervisory computer software, and be irrelevant with read write line.When three, using multi-functional encryption that card is set, the download of password and be read as machine automatically perform, also opaque to managerial personnel.Managerial personnel only need carry that special purpose system is provided with card and data storage card just can be finished data exchange operation, password read and checking is machine and automatically performs, alleviated the difficulty of management.
