- 收音机的原理是把从天线接受到的高频信号,经检波还原成音频信号,送到扬声器变成音波把接收到的电台高频信号,用一个变频级电路将它转化为频率固定的中频信号,然后再对这个中频信号进行多级放大,再检波,低放。由于不同频率的无线电波用途较广、接受的-The principle is the radio frequency signal received from the antenna, the reduction by the detector into an audio signal to the

- 吊瓶和药液被传感器所测重。随着药水的减少。重力传感器获得的数据用 zigbee传递给该程序后,对数据进行处理形成百分比转化为液面信息和药水滴完所剩余的时间,并将数据存入指定文件中,通过局域网链接,使得上手机端上能都看到液面和所剩时间,并液面快将为0时在电台平提示护士换药或者停药。-The bottle and the liquid is measured by the sensor weight. With the drops of medicine. Gravity sensor to obt
