Development Of Universal Debugging And Verifying Paltform For Missile Test Equipment

Missile test equipment plays an important role in the later period of the debugging and verifying of missiles and it is the key to determine whether missiles are qualified or not. The debugging and verifying platform for missile test equipment mainly depend on missiles. However, missiles are very complex and the development cycle for missiles is rather long, which directly affect the debugging、inspection、delivery of missile test equipment. Moreover, since usually missiles can not provide error data, the test coverage of the test equipment is difficult to assess. And the ability to find error can not be verified. In this paper, the universal debugging and verifying platform for missile test equipment is developed to provide the test and verifying environment for missile test equipment, so one can reduce the dependence on missiles in the process of developing missile test equipment.The debugging and verifying platform of missile test equipment is based on the information system structure TIA which is designed by hardware in the loop simulation. We use hardware platforms, which we already have, to package the hardware board. After that, TIA can support 1553 B bus and RS422 bus communication, and the platform can establish channels for analog signal s and digital signals transmission. The missile interface is modeled by object-oriented design method. The event response component is developed to response the 1553 B bus data, RS422 bus data, analog excitation, digital signal s which have been received according to the missile virtual model. The data source component is developed to produce a variety of analog data, digital data and communication data frame by loading different object models; The noise superimposed component is developed to produce many kinds of fault data which provides fault environment for missile test equipment and supports its full debugging and ve rifying; The clock synchronization component is developed to provide the time control for missile interface simulator. These components are associated by the ordering / publishing mechanism of the information system which realizes the data transmission between the components. The information interaction of distributed resources is achieved by using the middleware of TIA. And the expansion of the types of missiles is achieved by loading object model files. For a certain type of missiles, the simulation of missile test interface is realized under the control of the process control component of the information system by building missile simulation system.Some tests show that the platform is reliable and has good generality. And it can quickly construct a variety of missile test interface simulator.
