如下：
轿厢控制器主程序流程图如图4—2所示。初始化开中断后，控制器接收机房回传的信息，判断控制字，确定数据内容，分别调用相应的子程序实现显示。当轿厢控制器接收到内选信号，由INT0口产生中断并调用中断服务程序，将8255端口数据读入P8XC592，由PCA82C250在总线空闲时发送，中断服务程序流程图如图4—3所示。
5结束语
采用多主结构控制方式经对一台24层站电梯进行改造，改造前原系统电梯呼梯信号采用点对点传输连接方式，除了端站只需一进一出两根信号线外，其余每个层站都需要二进二出4根信号线，即N1＝(N－2)×4＋2×2，其中N1为外呼信号数，N为层站数，对应24层站电梯N1为92。相应的轿厢内选信号为N2＝N×2＝?48，而楼层显示需两位七段码加上两个方向指示则?需16根线，加起来总共需要156根。采用CAN总线技术改造后，由P8XC592和PCA82C250芯片构成了总线智能节点控制器，仅用4根连接线实现电梯机房、外呼和轿厢之间信号的串行通信，系统结构和连线简化，运行可靠性提高。经实际使用，故障率明显降低，运行效果良好。

Car controller main program flow chart shown in Figure 4-2. Initialize a disruption, the controller of the reception room to return the information to determine control of the word, the data content, respectively, call the appropriate routines to achieve display. When Cabin controller to receive signals in the election, by INT0 I have interrupted and call interrupted service procedures, 8255 will be read into the data port P8XC592, from PCA82C250 sent in the bus is idle, interrupt service program flow chart in Figure 4-3 Shown.
5 Conclusion
A multi-control mode as the main structure of a 24-point lift to be transformed and transform the original system before the elevator call staircase signal transmission using peer-to-peer connection, in addition to a single-station into a two signal lines, each of the remaining Of the stations are required, into two four signal lines, that is, N1 = (N-2) × 4 +2 × 2, which calls for foreign N1 signal number, N is the number of stations,
