三路红外线探头控制ISD2560语音播放。主要原理是正常情况下三对红外线接收管接收到各自配套对应的红外发射管的红外线，属于正常检测状态，一旦有一路红外管信号被隔断，侧启动语音芯片程序，播报警示提醒语音或报警。三对红外管可以根据使用需要，设置搭配报警程序。可用于各种排队系统。-three-way infrared probe control ISD2560 voice broadcast. The main principle is that under normal circumstances receive three pairs of infrared receiver to control their own matching the corresponding infrared emission of infra-red and is a normal state of detection, if there is way infrared control signals are cut off, side launched procedures voice chip, broadcast a warning to remind voice or alarm. Three pairs of infrared tube can be used, the police procedures set match. For various queuing system.
