Abstract:
Distributed control system focuses on the data acquisition， centralized management and centralized control of the circuit through independent multi-subsystem. Receiver and transmitter of power line share the same communication channel when message is transferred by terminals， which will give rise to data disorder. An anti-collision PLC technology based on CSMA/CA mechanism was proposed to solve the shortcoming， by which the stability and reliability of the communication could be improved. After analyzing the principle of data collision， the calculation model of the time which was used to transmit message between terminals simultaneously was established. Monte Carlo method was presented to compute the expectation of delay time. The feasibility of this technique was verified in engineering experiments. Sensitivity analysis was made to verify the factors that affect the delay time. The results provide a theoretical and practical basis of the design of intelligent lighting system.
