摘要
设计采用两组无线收发模块及AT89S51单片机作为新型报警器的控制与信号传输的核心,并配合编码译码芯片(SC2262\SC2272-M4)对信号进行编码译码。在位移传感器的作用下实现电动车受到微小震动时或有人体接近电动车蓄电池时发出报警声音并同时以两路不同的信号向遥控器发送报警提示,使遥控器的指示灯点亮,震动器和蜂鸣器工作发出报警信号。
This design adopts two sets of wireless transceiver and AT89S51 module as the signal transmission and control core part of a new type alarm, and combines with coding-decoding chips （Mode SC2262 ／ SC2272-M4） for working. With the effect of vibration sensor, it gives the alarm sound when electric vehicle bears the tiny shock or human body approach. And at the same time through two different routes, the signal is sent to the remote control, which makes the remote control light, alarm of vibrator and buzzer in operation.
