基于无线通信的优势，设计了一种新型无线遥控语音提示器。硬件设计部分以STC89C52单片机为控制核心；无线通信模块采用了nRF24L01，运用反射式红外传感器结合一套合理的计数方式，即可有效地区分出人员的进出。该语音提示器由感应端和接收端构成。感应端通过感应探头来判断是否有人员进出，若探头检测到有人员进入，会将感应信号通过无线发送给接收端。而接收端会通过语音芯片发出相应的语音提示，让用户知道有人到来。此外，该系统还具有红外遥控等特定功能。%A new type of wireless remote control prompter was designed based on the advantage of wireless communication. The prompter was designed based on STC89C52 single chip microcomputer as the control center; take the nRF24L01 as the wireless communication module, combined with a reasonable way of counting using a reflective infrared sensor, can distinguish the personnel pass effectively. The voice prompter was made up of a sensing end and receiving end. Personnel access was detected by the inductive probe in the sensing end and the access signal can be transmit to the receiving end by Wireless transmission Then the receiving end will prompt the corresponding voice issued by the voice chip, lets the user know someone come. In addition, the system also has infrared remote control function etc.
