| 摘 要： | 在MODBUS的基础上提出了一种多主站技术,该技术将网络上的多个主站分成一个责任主站和若干个监听主站。系统上电时,若干个主站采用竞争的方式产生一个责任主站;系统正常运行时,责任主站负责数据的收集,其他监听主站监听网络上的信息且存储,以保证收集数据的完整性;当责任主站发生故障时,其他监听主站采用竞争的方式产生一个新的责任主站而继续工作。该技术允许在多主多从的配置下,可以实现基于MODBUS的更加可靠的通信。

| Abstract: | Introduces a multi-master technology based on MODBUS,which divides all the masters in one network into one master-in-charge and several master-in-listening.While the system is powering on,the master-in-charge is generated through the competition among several masters;while the system is running,the master-in-charge is in charge of date collection,and the master-in-listening is listening and storing the data in order to keep the data complete.If the master-in-charge is out of order,the master-in-listening will compete for a new master-in-charge and then continue on the tasks.This technology makes the communication based on MODBUS securer in a multi-master and multi-slave system. |
