Optimization Design of Multi Serial Port Communication Based on Map-Reduce Technology

With the continuous development of computer technology, the demand for online monitoring in modern industrial enterprises is on the rise. In order to effectively meet the actual industrial field requirements of the serial communication capacity and quality, some technical treatment can be taken. On the one hand, multi-serial port software technology is used to realize serial communication concurrent operation; on the other hand, multi-thread technology is adopted to realize the reasonable allocation of serial communication resources. Firstly, the multi-serial port software communication architecture is established; secondly, by the multi-threaded means, to the communication resources of the serial port is optimize; finally, based on Map-Reduce technology, the multi-level mapping association between the communication data and the communication serial ports is established. The simulation results show that the multi-serial communication which based on the Map-Reduce technology not only improves the efficiency of multi-serial communication, but also effectively integrates multi-serial communication redundancy data.
