Description: 单工无线呼叫系统分发射和接收两大部分。发射部分采用锁相环式频率合成器技术， MC145152和MC12022芯片组成锁相环，将载波频率精确锁定在35MHz，输出载波的稳定度达到4×10-5，准确度达到3×10-5，由变容二极管V149和集成压控振荡器芯片MC1648实现对载波的调频调制；末级功放选用三极管2SC1970，使其工作在丙类放大状态，提高了放大器的效率，输出功率达到设计要求。接收部分以超大规模AM/FM立体声收音集成芯片CXA1238S为主体，灵敏度、镜像抑制、信噪比等各项性能指标均达到设计要求；音频功率放大器采用集成芯片LM386，电压放大倍数最大为200。采用PT2262/2272编码/解码电路实现了数据传输业务以及对台号的选择等功能；音频输入和数据输入可自动转换；AT89S52作为整个系统的控制部分，程序设计采用C语言在KEIL51的编译器上编程实现；显示采用128×64点阵型液晶显示。经测试，整机功能齐全，各项性能指标符合系统要求，接收波形稳定，无明显失真。-The simplex wireless-calling system consists of two parts: transmit part and receive part.The transmit part adopts the phase-locked loop pattern of frequency synthesizing technology and uses the MC145152 and MC12022 chips to compose the phase-locked loop.It locks the frequency of the carrier-wave at 35MHz.The stabilization of the carrier-wave can be 4×10-5,the accuracy can be 3×10-5.The frequency modulation and the confection of the carrier-wave are realized by the capacity-changing diode V149 and the integration voltage-control oscillator MC1648 chip.The end power amplifier uses the audion 2SC1970 to make it work in the third magnifying state,it improves the efficiency of the magnifier and the power of the output reaches the design demand.The receive part uses the super cosmically AM/FM dimensional sound stereo radio reception integration chip CXA1238S as the main part.The sensitivity、the mirror-control restrain、the SNR and every capability index all reach the design demand.The audio

Description: 用AT89S51单片机软件解码PT2262，编码芯片PT2262发出的编码由：地址码、数据码、同步码组成。地址码和数据码都用宽度不同的脉冲来表示，两个窄脉冲表示“0”；两个宽脉冲表示“1”； F” 一个窄脉冲和一个宽脉冲表示“,也就是地址码的“悬空”；同步码为时间较长的低电平间隔-AT89S51 MCU with software decoding PT2262, encoding chips PT2262 code issued by: address code, data code, synchronization code form. Address code and data codes are used to represent the pulse width of a different, two narrow pulses, said, " 0" two wide pulses, said " 1" F " a narrow pulse and a pulse width, said," that is, address code " Suspended " synchronization code is a longer time interval of the low

Description: 接收到的信号为发送信号的反码因为每检测到按键有效一次PT2262 都发送四次编码我们可以
利用这一特点来解码先检测有没有接收到信息当有的时候我们就去掉第一次编码的信号检测5ms 的
高电平来检测编码的开始信号接收到5ms 的高电平后才开始解码我们可以发现每个码的长度都是1.2ms
左右每一个编码都是由低电平开始然后到高电平又到低电平又回到高电平我们从第一个高电平
的宽度可以把1 码区分出来剩下的悬空码和0 码可以从第二个高电平的宽度区分出来
具体的单片机译码方法如下
由高电平开始检测到下降沿时就延时300us 读取接收的状态记为A0 然后再检测下一个下降沿
降沿后又延时300us 读取接收的状态记为A1 这样就把一个编码给译出来了

1 0 悬空
1 1 0 码
