Network Time Synchronization Technologies

MIL-STD-1553 communication protocol is popular and extensively used in avionics applications. In 1553 protocol, Bus Controller (BC) schedules data in terms of messages to Remote terminals (RT) on the communication bus (Node). Numbers of Electronic avionics systems are connected on 1553 for the data exchange with Bus Controller. Data messages i.e. traffic on the bus is monitored by Bus Monitor (BM) which display and store data for analysis. This scenario is simple for single node as only one BC is available. In the case of complex scenario where numbers of communication channels i.e. nodes are more than one, data exchange take place simultaneously and monitoring terminals (Bus Monitors) are equals to nodes for communication. Avionics system consists of 'n' independent nodes with n Bus Monitors that are connected separately and that are running independently. There is no sync between these nodes and Bus Monitor to start data capture as well as time reference of events. This problem is resolved by development of single Bus Monitor for all nodes of avionics systems connected. In this paper we are presenting the system development of Bus Monitor which captures the data from n nodes of 1553 communication with time synchronization on single computer. As only one computer and Multi node 1553 card is involved, this technology enhances the data analysis capability and also cost effective for the avionics applications, mainly in the field of Hardware In Loop Simulation (HILS) that is used for validation of avionic system's software in real time using multi node environment
