Description

Pen type bar code recognizer

The utility model relates to a kind of pen type bar code recognizer, belongs to the Application of Microcomputer field.

Along with improving constantly of China's scientific and technological level, Modern Traffic Control System also obtains swift and violent development.For example, for vehicle driver's management, progressively broken away from the pen of loaded down with trivial details backwardness of past and the ladder of management of paper, and entered advanced microcomputer management system.When the driver is violating the regulations, can be in the bar code recognizer with driver's license and violating the regulations type, time or the like various data-storings, and then various data are sent in the microcomputer management system by the data readback device, still, existing bar code recognizer remains in following defective:

1, photoelectric scanner separates with code translator;

Though the bar code recognizer that 2, has is bound up photoelectric scanner and code translator, this photoelectric scanner is made the slot type structure;

3, these bar code recognizers must be equipped with equipment such as keyboard, display, miniprinter and could use.

And, above-mentioned various bar code recognizers all exist volume greatly, not portable, weak point such as memory capacity is little.

The purpose of this utility model provides a kind of structure pen type bar code recognizer light and handy, easy to use that light pen scanner and primary controller are joined together.

Technical solution of the present utility model is: a kind of pen type bar code recognizer, it mainly is made up of light pen scanner, signal transformation circuit, primary controller, memory under program, data memory, network communication interface, auxiliary circuit and shell etc.It is characterized in that, said light pen scanner is arranged on the top of this recognizer, and light pen scanner and primary controller make one, and said primary controller writes down the pulse signal of light pen scanning and stores, after bar code is read in by correct scanning, hummer will send sound; Secondly its data-storing structure is: at first store driver's bar code data, storage management bar code data reads scanning at last and reads in the time, and with the FEH byte as the terminating symbol that once writes down.

According to above-mentioned pen type bar code recognizer, it is further characterized in that the operating voltage of said recognizer is 6V; The operating ambient temperature of recognizer is+40 ℃ to-20 ℃.And, the appearance similar of said recognizer is in a thicker pen, the shell of pen is made of the upper and lower two large divisions, the previous section of shell is narrower, the aft section broad, and its middle and upper part comprises battery case and communications connector etc., the bottom is provided with switch hole and hangs and do not wait, the light pen cap is arranged on the top of recognizer, and rain-proof cover is arranged on the end of recognizer, to be used to preventing that rainwater from entering in the communications connector.

The utility model has following advantage compared with the prior art:

1, the utility model pen type bar code recognizer is made one with light pen scanner and primary controller, and its structure is light and handy, volume is little, easy to use.Therefore, when the traffic policeman is on duty, can be contained in it in the breast pocket or hang on the waistband; And operating temperature range is wide, can be high temperature resistant, winter protection is frozen, shockproof and rainproof, be suitable for open-air the use.

2, in this bar code recognizer, be provided with bigger memory size, be convenient to storage, and have power-down protection.Like this, the traffic policeman can both store easily to all process informations violating the regulations of traffic violation person in the whole process of executing the task.

3, the communication interface of this bar code recognizer and microcomputer link, to guarantee the reliability and the dirigibility of communication.After the traffic policeman is laid off, adopt signal procedure just can easily the various information of bar code recognizer be repaid in the microcomputer.

Be elaborated below in conjunction with the instantiation of accompanying drawing to the utility model pen type bar code recognizer.
