基于CAN总线技术,以AT89C51为核心,采用Intel82526及PCA82C250构成的电梯监控系统,通过主控制器与轿厢、门厅控制器间的通信,完成了对电梯的控制,并可进行远程监控。对通讯中出现的冲突采用非破坏性仲裁的方法解决。
Based on CAN bus technology and AT89C51 as the core, an elevator monitoring system composed of Intel82526 and PCA82C250 is adopted. Through the communication between the main controller and the car and hall controller, the elevator control is completed and remote monitoring can be carried out. Conflicts in communications are resolved using non-destructive arbitration.
