【摘要】 利用热释电红外探测模块,数字编译码双功能集成电路及无线电收发模块等器件,设计了远距离无线遥控数显报警系统。由于该系统采用了数字编码技术,因此一台接收主机可以设置数台报警分机,可同时监视多个报警点,报警半径约为3000m左右,适合在库房、商店、矿山等场合使用。更多还原

【Abstract】 A far distance radio control alarm system is designed using pyroelectric infrared detecting module,circuit of double function of code and radio receiving and transmitting module. Because of numeric coding technology is used,one receiving host can configurate several alarm terminal,monitor several alarm set point which alarm radius arrive to about 3000m. It can be used in storeroom,shops and mines.更多还原
