Terminal Power Supply Monitoring System Design Base On TTCAN

Shipping in economic development is playing an increasingly important role, in orderto solve pollution of the ship to berth in port arising, ship shore power technology has beenwidely used, but with the electricity increasing the mobility of the ship, arriving ships to useshore power management more complex, in order to effectively solve this problem, and alsothe monitoring system in order to meet the real-time information, the issue TTCANcommunication mechanism is proposed based power monitoring and management ofterminal program.The real-time of terminal power supply control system depends on real-time ofTTCAN network, so you can optimize the TTCAN system matrix (static scheduling table)to improve real-time monitoring system, the traditional way of using the average allocationoptimization algorithm, which has been unable to meet the real-time of the systeminformation; traditional genetic optimization algorithm fitness function can not be wellreflected in the optimization objectives. The subject of TTCAN system matrix by building amathematical model, a detailed analysis of the system matrix of the parameters in the designprocess, and gives the formula for calculating the parameters, in order to better design thesystem matrix, the matrix of the system put forward three constraints conditions, so thatsystem matrix can quantify the design process; and made improvements based onletter-coded genetic optimization algorithm, the network information system matrix into amatrix form letters, combined with mathematical models to real-time rate as the informationgenetic optimization algorithm fitness function, which well reflects the optimization goals.Through simulation experiments and field commissioning, the static scheduling table afterthe letter-coded genetic algorithm to optimize to meet the real-time requirements.For electricity in the characteristics of the ship’s arrival, the subject of design of theterminal sub-station control panel power control hardware and software, remote monitoringand management of terminal software. Taking full account of the scene under the premise ofinterference, CAN bus communication circuit using a digital isolation technology; terminalsub-station power monitor and keyboard with OLED displays, making it easier to operationof electricity users; for each node in the system clock is not uniform pace, through thesoftware design so that all nodes have unified network time unit (NTU), thus ensuring theunity of time each node; terminals for power supply monitoring system in data complexity, design based on SQL Sever2005database, enabling the effective management of systeminformation. Through the application of Sanjiangkou Fujian ports, illustrate the program’sreliability, real-time communication system to reach the desired results.
