Abstract

The utility model relates to a traveling crane identity inquiry display unit which is characterized in that the unit comprises CCD scanning head or laser scanning head, main control circuit and control key and liquid crystal display, wherein the CCD scanning head or the laser scanning head reads the vehicle-mounted bar code information into microprocessor which transmits the compared data and display instruction information to the liquid crystal display. The device can make the management of non-motor vehicles exceed scientification so as to identify vehicles and solve the problem of searching the lost vehicles and at the same time can monitor the tax situation of the vehicles.

Description

A kind of bicycle display for inquiring identity

Technical field

The utility model relates to a kind of portable bicycle display for inquiring identity.

Background technology

As everyone knows, China is bicycle big country in the world, and national bicycle owning amount is near 1,000,000,000, huge owning amount like this, and its management method still adopts the licence of enabling the sixties that travels to add the original management method of the formula system of listing.Employed the listing of this method can not directly record identity information or other management information of closing the car owner.Obviously, the old non power driven vehicle management method development trend of the current China of incompatibility bicycle.At present, China's non power driven vehicle management status is: the vehicle owning amount continues to expand, the aggravation of managerial confusion runaway condition, the serious and tax position and pessimistic of the stolen phenomenon of vehicle.

Technology contents

The utility model utilizes vehicle-mounted bar code and computer-controlled reading device, solves the problem to bicycle ID inquiring and demonstration.

The technical scheme that the utility model addresses the above problem is: it is made up of CCD scanning head or laser scanning head, governor circuit and control button and liquid crystal display three parts; The vehicle-mounted bar code information that described CCD scanning head or laser scanning head will be distinguished reads in the microprocessor CPU by serial port chip, and promptly 11 of serial port chip, 12 pin are connected with 11,10 pin of CPU; The pin 21-39 address wire of described CPU selects chip to be connected with data memory by address buffer chip and sheet, under read-write steering logic chip controls, order format according to CPU, scan-data is stored in the data-storing district, and data are compared processing according to cpu instruction, data after the processing are also store and are got back in the memory, data sink after CPU will handle together is transferred on the LCD with idsplay order information, described governor circuit is by described CPU, address buffer, sheet selects chip, read-write steering logic chip, eight bus transceivers, serial port chip, storaging chip and page turning operating key are formed, and described page turning operating key is located at the P of CPU ₁₀Mouthful.

The utility model is held bar code content in the governor circuit of scanner reads in the scanner by hand, and is presented on the LCD.The law enfrocement official can consult the contained content of bar code by function key, for example according to demonstrating personal identification number, can if personal identification number is not inconsistent, can predicate robber's car to holding car people inquiry, and can lose the car people by relevant department's notice according to identification card number in the bar code and claim.The enforcement of this device, can make vehicle management be tending towards scientific, vehicle lose phenomenon can be controlled.

Description of drawings

Fig. 1 is that the bar code that bicycle described in the utility model or other bicycle use is implemented illustration;

Fig. 2 is the profile synoptic diagram of bicycle display for inquiring identity described in the utility model;

Fig. 3 is the governor circuit schematic diagram of bicycle display for inquiring identity described in the utility model;

Fig. 4 is the bar code installation site figure that bicycle described in the utility model or other bicycle use.

Embodiment

Bicycle bar code among Fig. 1 can comprise contents such as personal identification number, ID (identity number) card No., tax status.Can distinguish the time with different background colors in addition.It can be fixed on below-seat, and is wet by the rain and burnt by the sun to prevent.

Among Fig. 2, the scanner head 1 of scanner is positioned at the place ahead one side.Scanning switch 2 can be arranged on the handle front end of below.Function operating key (page turning key) can be arranged on the handle rear end of below.Governor circuit can be provided with reportedly outlet of a number, and this transmission mouth 4 can be located at the handle rear end below.Liquid crystal display 5 can be arranged on the rear of main frame.

Circuit part is seen Fig. 3, and the read coding mode of the data of CCD scanning head by determining passes through U with data ₇Special-purpose serial port chip is according to microprocessor U ₁Order format, by U ₁Pin 21-39 address wire, through address buffer chip U ₄Select chip U with sheet ₂, and be equipped with read-write steering logic chip U ₈, store data-storing district U ₅, this storage portions is the 8K data memory, U ₄With data buffer U ₆Combination.Microprocessor U ₁To contrast the back data processed result and pass through U ₂Carry out sheet choosing, and through the data buffer with data sink with the idsplay order information transmission on 6256 LCD.T among the figure ₁Offer cpu clock signal, C ₁-C ₁₃Be that clutter on the appearance elimination power supply, R are met in decoupling ₁∽ R ₆Be the logic pull-up resistor.U ₃Be eight bus transceivers.

Claims

1. bicycle display for inquiring identity is characterized in that: it is made up of CCD scanning head or laser scanning head, governor circuit and control button and liquid crystal display three parts; The vehicle-mounted bar code information that described CCD scanning head or laser scanning head will be distinguished reads in the microprocessor CPU by serial port chip, and promptly 11 of serial port chip, 12 pin are connected with 11,10 pin of CPU; The pin 21-39 address wire of described CPU selects chip to be connected with data memory by address buffer chip and sheet, under read-write steering logic chip controls, order format according to CPU, scan-data is stored in the data-storing district, and data are compared processing according to cpu instruction, data after the processing are also store and are got back in the memory, data sink after CPU will handle together is transferred on the LCD with idsplay order information, described governor circuit is by described CPU, address buffer, sheet selects chip, read-write steering logic chip, eight bus transceivers, serial port chip, storaging chip and page turning operating key are formed, and described page turning operating key is located at the P of CPU ₁₀Mouthful.
