Control Simulation

The Key Problem of Command&Control Simulation is to solve how to communicate between Command&Control information and operation models of simulation system. Aiming at such problem, the BML and BOM technical are used together. Meanwhile, both models are presented in XML. Thus the Command&Control Simulation System Framework is built. At the same time , the basic solution thought for the key problems during the building of the simulation system has been put forward .

In order to simulate the multi-sensor signals of the train integrated positioning system, and make signal fusion and verification, the train integrated positioning signal simulation system is introduced in this paper, which is based on GNSS and multi-sensor integrated positioning thoughts, the mathematical models and failure characteristics of the sensors are analyzed, the pulse speed sensor and gyro error models are established, the data simulation approach and data acquisition modules are adopted to simulate pulse speed sensor and gyroscope signals, the GNSS simulator is used to simulate GNSS signal under different scenes and conditions, signal fusion algorithms are used to conduct fusion and filtering of the integrated positioning signal. The results show the availability of the simulated signals. The train integrated positioning signal simulation system provides test environments with the parameters controllable, and lays a good foundation for the researches of the Beidou based integrated positioning system and the multi-mode satellite positioning technology.
