The Design Of Police Satellite Communication Command Vehicle System Based On OTM

The design and implementation of the police satellite communication command vehicle system of "Communication in Moving" are given in this dissertation. The system is mainly used for the fast and reliable communication between the police satellite communication command vehicle and police command center, by the "Communication in Moving" technology. Base on Global Position System, inertial navigation equipment and SINS/GPS Integrated Navigation Algorithm is adopted in the communication command vehicle.Inthis paper,author emphasizesthe specific requirements of the vehicle moving satellite communications command vehicle.And the satellite communications command vehicle function are analyzed in detail, the function of each part.Develop the satellite communication commanding vehicle design principles, on the basis of the analysis of the city’s communications command vehicle specific needs and command vehicle the function relationship based, given the satellite communication commanding vehicle with design specifications.Then introduces the communication command vehicle compartment design modifications, including car body design of doors and windows, work station and rack design, car fixed equipment design, load structure design of each functional zone of the balance and weight design, communication and command vehicle structure design, electromagnetic compatibility design, accessory equipment etc...In the "three defenses" design, the maximum considering long and cold winter of characteristics, this point in the command vehicle power supply design are also reflected.Based on the analysis of the characteristics of the strapdown inertial navigation system of SINS / GPS are commonly used in various coupling modes, according to the satellite communication commanding vehicle demand and combined with local characteristics is the system in the loosely coupled combination process.With the satellite communications command vehicle system design of the servo system of the functional components, and specific design.At the same time of satellite communication commanding vehicle tracking system are described, and gives the specific design in the application of technology, makes the analysis on the key components of the satellite communication commanding vehicle technology, made brief description of specific selection.The analysis of satellite communication commanding vehicle information processing based on the composition and structure of system, according to the software structure of information processing framework design of the system software.Using VC++6.0 as the main programming tools written information processing system software interface, including the main interface design, interface design of antenna motion, initial alignment and finding star set interface design, data display dialog box design, and gives the code examples and the interception of the part of the application program interface.Finally, the system testing is completed, the specific contents include: two part of single module test and normal test.The test results show that the modified the design of satellite communications command vehicle can work normally.The design of the system is verified by the experiment, the effect is good, can provide the service for the police command handling emergencies effectively.
