摘　　要：为了便于编码芯片PT2262在门禁控制系统领域中的应用,从PT2262与韦根信号的编码原理和波形特征入手,通过软硬件结合的方法实现了将PT2262编码发射器的无线信号接收并转换为韦根26信号输出,并给出了相应的系统框图、电路原理图以及单片机程序。测试表明,此方案应用方便,可靠性好,成本较低,具有较高的实用价值。To facilitate the application of encoding chip PT2262 in the field of entrance guard control system,proceeding from the coding principle and waveform characteristic of PT2262 and Wiegand signal,the reception of the wireless signal from PT2262 encoding transmitter and conversion of the signal into Wiegand signal output were implemented with the method of combining the software and hardware. The corresponding system block diagram,circuit principle diagram and single-chip microcomputer program are given in this paper. The testing results show that the scheme has convenient application,good reliability,low cost and high practical value.
