Abstract
The utility model relates to a switching circuit, particularly a circuit which uses human body's static electricity to swith on and switch off a switch through an electric conducting printing ink electrode. The utility model comprises an electric conducting printing ink electrode plate, a resistor and a transistor switch array. The utility model is characterized in that the electric conducting printing ink electrode plate is connected with the transistor switch array through the resistor, and the electric conducting printing ink electrode plate can also be connected with an input port of a monolithic computer through the resistor. The utility model has the advantages of high sensitivity, large quantity of metal saving, switch device protection, etc.
Description
The utility model has related to a kind of switching circuit, is specially adapted to electrically conductive ink electrode static electricity on human body switch.
The metal electrode soft-touch control and the dry-reed relay of prior art belong to forceful electric power and high-voltage applications.It has advantages such as easy to operate, long service life, but it is under some working condition, and sensitivity is not too high, production efficiency is lower, cost is higher relatively.
The purpose of this utility model is to provide a kind of highly sensitive, is used for the effect that the static electricity on human body can reach switch.
The utility model is realized by the following technical solutions: the utility model comprises electrically conductive ink battery lead plate, resistance and triode switch array, it is characterized in that the electrically conductive ink battery lead plate is connected with the triode switch array by resistance.
The utility model can also be connected with the monolithic computer input port by resistance by the electrically conductive ink battery lead plate.
That the utility model compared with prior art has is highly sensitive, save advantages such as a large amount of metals and device for switching.
Description of drawings of the present utility model is as follows:
Fig. 1 is a circuit connection diagram of the present utility model.
Fig. 2 is array circuit figure of the present utility model.
Below in conjunction with description of drawings the utility model is described in further detail: as shown in Figure 1, the utility model comprises electrically conductive ink battery lead plate, resistance and triode switch array, and the electrically conductive ink battery lead plate is connected with the triode switch array by resistance.Perhaps the electrically conductive ink battery lead plate is connected with the monolithic computer input port by resistance.The electrically conductive ink electrode can be imprinted on the carbon slurry of conduction, silver-colored slurry or copper slurry etc. on the single-side coated copper plate and with the carbon slurry via hole new technology circuit that each electrode is corresponding with copper-clad surface with the method for silk screen printing and connect.Electronic component comprises 10M---30M resistance, 9014 triodes, single-chip microcomputer.64 little square electrically conductive ink battery lead plates on instrument surface are connected with 64 9014 transistor bases respectively by the lead of printed wiring board, each base stage is all by a 10M grounding through resistance, and the collector and emitter of each triode is connected respectively to monolithic computer input port A (8) and input port B (8).When human body contact printing ink electrode, the static electricity on human body conducts to transistor base by the printing ink electrode, makes the triode conducting, and collector electrode becomes electronegative potential by high potential, is equivalent to push-button switch and connects.As shown in Figure 2,64 triodes that 64 printing ink electrodes on the instrument face plate connect respectively with it, be to be connected on two input ports of 8 * 8 monolithic computer with matrix form, and retrieve each incoming line state by the software program of monolithic computer, have or not key to be touched or which key is touched by point with differentiation by point.Computer is just found out corresponding several electrodes by the position of the utmost point that gets an electric shock and is conducted to transistor base from memory, make word information, convert analog signal to by D/A, after a series of amplifications, run out required voice again by loud speaker, improved circuit has saved triode, parameter has adjustment slightly, but the course of work is the same.
When using electrically conductive ink electrode static electricity on human body switch, as long as any position of human body (being generally finger) contact electrically conductive ink electrode, the electronic switch action that links with it, even in the human body airborne, or copy paper also can regular event on human body contact site and the electrically conductive ink electrode gap.Teacher's classroom instruction for convenience, Chinese phonetic alphabet RP Teaching instrument and International Phonetic Symbols RP Teaching instrument press for a kind of electrode, its effective area is big, and the on-off mode highly sensitive, that production efficiency is high is to replace existing dry-reed relay contact-making switch mode.Because the characteristics of these two kinds of instruments are that required switch and is arranged with preface all more than 70 on the same panel.The method that adopts the electrically conductive ink electrode to print electrode can significantly reduce production and processing man-hour of switch.The operating procedure of pronunciation Teaching instrument is as follows: instrument is inserted 220V AC mains supply, press mains switch, power supply indicator is bright, and instrument enters operating state.This moment, the teacher touched any position in the electrically conductive ink electrode zone that the dashboard face is printed on letter with teacher's pointer or finger point, and instrument promptly sends corresponding sound.The high-grade variety of this instrument possesses and combines into syllables and Presentation Function, but searching principle and operating procedure are same, just the size differences of information software capacity.
