Title

(EN) INFRARED TOUCH FRAME CIRCUIT BOARD, INFRARED TOUCH FRAME, AND INFRARED TOUCH SCREEN

(FR) CARTE DE CIRCUIT IMPRIMÉ DE CADRE TACTILE INFRAROUGE, CADRE TACTILE INFRAROUGE ET ÉCRAN TACTILE INFRAROUGE

Abstract

(EN) An infrared touch frame circuit board, an infrared touch frame, and an infrared touch screen. The infrared touch frame circuit board comprises a host board and a plurality of slave boards; the host board comprises a signal conditioning circuit; the signal conditioning circuit comprises a plurality of sampling resistors; each slave board comprises an infrared receiving circuit; the infrared receiving circuit comprises a plurality of optical signal receiving diodes and a plurality of amplifying transistors; a first end of each optical signal receiving diode is used for receiving an optical signal receiving diode enable signal; a second end of each optical signal receiving diode is connected to a signal input end of one amplifying transistor; a first connection end of each amplifying transistor is grounded; a second connection end of each amplifying transistor is connected to one sampling resistor by means of an analog signal bus; the sampling resistors are connected to a power supply end. Since all the amplifying transistors are connected to the power supply end of the host board, there is no need to provide on the slave boards a power supply for each amplifying transistor, thereby reducing the difficulty of wiring.

(FR) L'invention concerne une carte de circuit imprimé de cadre tactile infrarouge, un cadre tactile infrarouge et un écran tactile infrarouge. La carte de circuit imprimé de cadre tactile infrarouge comprend une carte hôte et une pluralité de cartes esclaves ; la carte hôte comprend un circuit de conditionnement du signal ; le circuit de conditionnement du signal comprend une pluralité de résistances d'échantillonnage ; chaque carte esclave comprend un circuit de réception infrarouge ; le circuit de réception infrarouge comprend une pluralité de diodes de réception de signal optique et une pluralité de transistors d'amplification ; une première extrémité de chaque diode de réception de signal optique est utilisée pour recevoir un signal d'activation de diode de réception de signal optique ; une seconde extrémité de chaque diode de réception de signal optique est connectée à une extrémité d'entrée de signal d'un transistor d'amplification ; une première extrémité de connexion de chaque transistor d'amplification est mise à la terre ; une seconde extrémité de connexion de chaque transistor d'amplification est connectée à une résistance d'échantillonnage au moyen d'un bus de signal analogique ; les résistances d'échantillonnage sont reliées à une extrémité d'alimentation électrique. Étant donné que tous les transistors d'amplification sont connectés à l'extrémité d'alimentation électrique de la carte hôte, il n'est pas nécessaire de fournir sur les cartes esclaves une alimentation électrique pour chaque transistor d'amplification, réduisant ainsi la difficulté de câblage.

(ZH) 一种红外触摸框电路板、红外触摸框以及红外触摸屏，红外触摸框电路板，包括：一个主机板和多个从机板；主机板包括信号调理电路；信号调理电路包括若干个采样电阻；从机板包括红外接收电路；红外接收电路包括若干个光信号接收管以及若干个放大管；每一光信号接收管的第一端用于接收光信号接收管使能信号；每一光信号接收管的第二端与一个放大管的信号输入端连接；放大管的第一连接端接地；放大管的第二连接端经由模拟信号总线与一个采样电阻连接；采样电阻连接供电端。放大管统一连接主机板的供电端，无需在从机板上为每个放大管布设电源，降低布线难度。
