Abstract
The utility model discloses a Chinese character magnetic card controller which is arranged between a microcomputer keyboard and the interface of the microcomputer keyboard in a connecting manner. The utility model is characterized in that the utility model comprises a single chip microprocessor, an analog switch, and a gate circuit; the signals and the address output of the single chip microprocessor are connected with a magnetic card reader-writer; one path of the signal port (A) of the microcomputer keyboard is serially connected with the gate circuit through the output of the analog switch and is also connected with the signal input terminal of the single chip microprocessor, and the other path of the signal port (A) of the microcomputer keyboard is connected with a microcomputer keyboard port (B); other signal output ports of the single chip microprocessor are also connected with the output terminal of the analog switch through the gate circuit. The utility model has the advantages that function of information display is enhanced for magnetic cards, and structure is simple.
Description
The utility model relates to the making of magnetic card control.
What existing magnetic card control only was used for numeral and letter writes and reads (demonstration), can not show and write Chinese character information, along with the expansion of magnetic card purposes, the demonstration of Chinese character information is necessary, and the utility model purpose is to make a kind of Chinese character magnetic card control under microcomputer and keyboard support.
Technical solution of the present utility model is: the Chinese character magnetic card control that inserts between microcomputer keyboard and microcomputer keyboard interface, comprise chip microprocessor, analog switch and gate circuit are formed, the signal of chip microprocessor and address output connect the magnetic card read write line, microcomputer keyboard signal port (A) is leaded up to analog switch output serial connection gate circuit and is connected the signal input part of chip microprocessor, another road connects microcomputer keyboard mouth (B), and the other signal output port of chip microprocessor also connects the output terminal of analog switch by gate circuit.
Under computer operating system, under the management of chip microprocessor, realized the input method of simulation microcomputer keyboard with the utility model.The control of magnetic card keyboard controller receives the scan code of keyboard input character (comprising Chinese character), decompose the keypad character scan code that to write the keypad character scan code of card or need not write card through chip microprocessor identification, finish receiving after operator's information of stamping the card can write automatically.Microprocessor is put card reading status earlier, earlier identification REL and identification keyboard, the RCL signal reads card information earlier and send RAM in this way, verification to the time, then send a string information to microcomputer.As non-RCL, then judge whether the key symbol or the Chinese character information sign indicating number of keyboard input, required input magnetic card keypad character or Chinese character information sign indicating number provide 1 by microcomputer keyboard to be determined to several home keys, runs through to change over to after the signal code to write card programmed control magnetic card read write line and write card.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model line assumption diagram, 1 and 2 human hair combing wastes of keyboard delivery outlet (A) send keyboard signal (scan code), this scan code is sent into microprocessor IC1(respectively through analog switch IC2 chip (available 4066) can be with 8051) 1 and 2 pin and send into 1 and 2 pin of microcomputer keyboard interface (B), microcomputer is received the back display process, IC1 differentiates whether write card information to the scan code of receiving, write card information in this way, just send into internal memory, at this moment be still scan code (keyboard input sign indicating number) what internal memory was deposited, after writing card information input and finishing, Chinese character magnetic card keyboard controller changes the card program of writing over to, write on the card is a string key symbol scan code of being sent into by keyboard, and the front and back order is constant, scan code can be a kanji code, can export the scan code of multiple form because of microcomputer keyboard, so controller can be delivered to various key symbol scan codes magnetic card read write line M and deposit magnetic card in, the readout of magnetic card such as following: after a magnetic card that has write Chinese character scan code or other key symbol scan code read in the Chinese character magnetic card control, this device simulating keyboard sending method with a string information through IC1 and 10,11 pin, the OC gate circuit is sent into 1 of microcomputer keyboard interface (B), 2 pin, IC2 closes 1 of IC1 simultaneously, 2 pin close to be read.
The utility model utilizes microcomputer keyboard interface and Chinese on computer input technology to support magnetic card, thereby allows the card information Presentation Function strengthen, and is simple in structure, just with applying.
Claims (1)
1, a kind of Chinese character magnetic card control that between microcomputer keyboard and microcomputer keyboard interface, inserts, it is characterized in that: comprise chip microprocessor, analog switch and gate circuit composition, the signal of chip microprocessor and address output connect the magnetic card read write line, microcomputer keyboard signal port (A) is leaded up to analog switch output serial connection gate circuit, the signal input part that connects chip microprocessor, another road connects microcomputer keyboard mouth (B), and the other output signal port of chip microprocessor also connects the output terminal of analog switch by gate circuit.
