A Visible Light Communication Link Protection Mechanism for Smart Factory

In recent years, wireless networks and applications have achieved marvelous successes in government, enterprise, home, and personal communication systems. The desired features of wireless communications draw lots of attention to the industrial communication and expected to bring benefits such as reduce deployment and maintenance after employed. However, the industrial communication system required real-time communication, which means the control systems in the factory are required accurate control and rapid communication, such as the industrial motion control system. In this type of application, the communication system performance and efficiency will be evaluated to ensure it applicable to the industrial network. However, there are a few original issues in the wireless communication, such as fading, multipath propagation and interference problems, which will affect the reliability and performance of industrial communication system operation. Therefore, we proposed a connection protection mechanism that cooperates with wireless network and visible light communication to achieve reliability and performance in industrial communication network. We will consider implementing this mechanism by using industrial wireless Ethernet in the near future.
