N语音通信系统的Petri网建模与仿真
Petri Net Modeling and Simulation of CAN voice communication system
因为CAN总线的直接通信距离只有10km左右，而且由于收发器驱动能力的限制，总线上最多只能挂110个节点，这给基于CAN总线的语音通信系统的组网带来了一定的困难。CAN中继器就是为了解决这个问题而设计的，CAN中继器可以实现对CAN数据信号的增强和转发，不仅扩大了通信距离，还增加了总线上节点的最大数目。通过在语音系统中增加CAN中继器可以实现对整个矿井的覆盖。本文利用Petri网对增加了CAN中继器的语音通信系统进行了建模仿真，并对仿真结果进行了深入的分析，得到了系统的收包率和数据时延的定量关系。
Because of the direct communication distance of CAN bus is only 10km, and restrictions on transceiver driving ability, the node can only be linked up to 110 on the bus. This makes some difficulties on the voice communication network based on CAN-bus. CAN Repeater is designed to solve this problem. The data signal can be strength and forward by CAN repeaters, it not only expands the communication distance, but also increases the maximum number of nodes. By addition of CAN repeater the voice system can cover the entire mine. In the paper, the voice communication system is modeling and simulating by Petri Net, and makes a in-depth analysis of the simulation results, and get the quantitative relationship between system received data packet rate and time delay.
