CPU-5CE/32-85-2 FORCE软件结束
ATmega48芯片具有4 KB内部Flash和512字节的片内SRAM,软件结束需考虑资源分配问题,特别是SRAM使用状况。因为程序触及串口通讯、DTMF通讯和FSK通讯3种状况,理论上需求拓荒6个缓冲区。如果这样,每一个缓冲区的大小明显不能保证抵达实践通讯数据量的需求。结合FSK通讯特征,DTMF数据传输与FSK数据传输不可能同时发生,因此FSK与DTMF可共用相同缓冲区。相同串口接纳与FSK发送、串口发送与FSK接纳都不会同时发生,这样通讯只需求拓荒两个缓冲区就能够保证模块正常通讯,考虑实践业务途径数据量状况,软件规划中为FSK接纳拓荒255字节缓冲区复用;FSK发送拓荒45字节缓冲区复用。
4.1 CPU-5CE/32-85-2 FORCE主程序结束流程
图2 CPU-5CE/32-85-2 FORCE主程序流程
通讯模块主程序包含:CPU初始化、CMX865初始化、初始化建链、串口通讯和FSK通讯子程序等。主程序流程如图2所示。初始化建链环节是模块正常作业的根底,经过初始化建链操作,信息终端能够依据线路环境以及途径超时机制对通讯模块参数进行设置,保证通讯的稳定性。通讯主流程循环实施3个子功用函数:线路状况处理函数、串口数据解析与处理函数、链路坚持函数。线路状况处理函数规划了3种线路状况,即初始状况、闲暇状况和摘机状况;正常作业时仅在闲暇状况和摘机状况之间切换。其间在闲暇状况检测振铃、依据状况位实施摘机、DTMF拨号等操作;在摘机状况依据状况位实施FSK收发、脱线检测、挂机操控等操作。串口数据解析与处理函数包含串口数据按指令集解析、对解析指令进行应对和状况置位处理部分。这样线路状况处理函数和串口数据解析与处理函数经过状况置位标志紧密连接起来。FSK数据选用连续方法直接接纳,接纳完毕后在摘机状况下直接经过串口发送给信息终端。因为串口发送使用相对单一,为简略处理串口发送选用即时应对处理方法,涣散在通讯主流程各子功用函数中结束,提高了通讯功率。经过链路坚持函数判别串口通讯是否异常,通讯模块周期性地向信息终端发送链路坚持指令,如果3次重发均未收到终端应对指令,通讯模块将主动锁闭线路,重新实施初始化建链操作,结束串口异常的处理。
4.2 CPU-5CE/32-85-2 FORCE对外串口通讯协议
模块选用规范串口通讯,波特率为19 200 bps,10位异步方法。界说串口通讯数据包格局为:0x1E+指令+校验和反码(对指令的校验和反码),其间部分指令以变长方法发送。串口通讯指令有:模块初始化、链路坚持、DTMF接纳/发送、FSK接纳/发送、振铃、挂机等,指令详细格局和描绘此处不加胪陈。模块初始化上电后由通讯模块主动主张,直到正确接纳到终端应对初始化指令后,通讯模块才建链成功。信息终端初始化应对指令供给FSK通讯模块参数配置信息。上电后如果FSK模块未收到终端初始化应对信息,则周期性地(每2 s)发送一次初始化建链指令,直到成功停止;模块FSK通讯过程中周期性地向终端发送链路坚持指令,如果未收到终端应对信息,则断开FSK链接重新开始模块初始化。
4.3 串口通讯结束
AVR单片机串口通讯往往选用SPI通讯方法[78],通讯模块串口通讯选用UART0操控/状况寄存器和数据寄存器结束。串口通讯子程序由串口发送/接纳连续子程序、串口接纳指令解析子程序和串口组包发送子程序3部分组成
