本系统利用凌阳SPCE061A单片机原理,设计了一种双向超声测距系统,与一般的超声测距系统相比,除具备一般测距系统具有的功能外,该系统还具有低功耗、高精度、工作可靠、人机交互界面友好等优点。由于超声传播速度与环境温度相关而采用声速温度自动补偿技术,根据测量不同距离和不同的反射材料,回波信号强度从几毫伏到几百毫伏变动,因而采用两片AD603组成AGC自动增益控制电路与低噪放大器 NE5532 级联使用的方式组成超声检测信号放大电路,提高超声检测系统的检测范围和系统的适应性,使的系统获的较好的整机性能。由于超声波的传播距离与它的振幅成正比,为了使测距范围足够远,可对单片机输出方波信号进行功率放大后再加在超声波换能器上,因而先由三极管8050进行功率放大,再通过由六非门CD4049接成推挽方式的驱动电路将振荡信号的幅度放大一倍,再接到超声波换能器,从而增加了超声波的传播距离,扩大了测距范围。-err

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.
