Abstract:Making use of rich inner resource of FPGA(Field
Programmable Gate Arrays),摘要：充分利用内部资源FPGA（现场可编程门阵列)
a wireless alarm sending system is designed.被设计成一种无线警报输出系统.
It includes encoder,FSK(Frequency Shift Keying)
modulation and every channel!它包含编码器,FSK（频移控件）
ˉs control circuits 控制电路,which can
decrease volume and increase reliability of the alarm system.这种控制电路可以
减少音量 和 增加 报警系统的 可靠性.
The demodulation of receive system is realized by an
application specific integrated circuits MC3372.接收解调系统的实现是通过一个
特定应用集成电路MC3372.
With the help of a single-chip microcomputer 89C51,在单芯片电脑 89C51的帮助下.
the address decoder is also designed in the receiver.地址解码器地址也被设计在接收器下.
Adding to other anti-interference,加上其他的反干扰,
the alarming system has effectively decreased the error-alarm
rate.报警系统 更好的减少了报警错误的概率.
The system can install up to 128 channel sending devices.
系统能够 安装 128个 输出通道.
It can send an alarm to the host when there are some cases in
stand-off areas,当有情况在 疏离 的区域,它能发送警报到主机.
and the system will display on rotation multiple 系统将会多次循环上演案件.
cases!ˉ area codes .区域代码 The transmission distance is greater than
4Km in open zones.传输距离大于开放区域4KM.
User can install more than one type sensors
simultaneously,用户能够安装超过一种模式的感应器.
for example,smog sensor,combustible gas
sensor or burglar sensor.例如,烟雾感应器,气体感应器,防盗传感器
Experiments show that the wireless alarm system has the strengths of high reliability,
实验表明 无线报警器有更好的可靠性.
high
anti-disturbance ability 更高的仿干扰能力and low error-alarm rate.和更低的错误报警率
It can entirely meet the needs of alarm fireproofing and guard against
theft,etc.这个能够完全迎合防火报警器和防范小偷的需要
