| Abstract: | Introduces the wireless machine of grabbing for replying and displaying theresult, which has the function of judgment with 8 channels of grabbing for replying. It does need to distribute the electrical wire, so it is moved expediently. Chooses the familiar coding-decoding chip PT2262/2272 that forms the data coding-decoding circuit. The wireless emitter is composed of the FM modulate circuit, and the wireless receiver is composed of the FM demodulation chip MC3362. Chooses the AT89C52 SCM as main controlling chip, which can control by real time and display the result currently. Reserves RS-232 to communicate with PC to enhance its function. |
