Based On The Cpci-bus Ann Control Testing Card Design And Implementation

With the rapid development of military technology and techniques, a lot of high-tech weapons are developed, including some unmanned aerial vehicle. Because of their huge lethality, it is bound to result in unpredictable and disastrous consequences, if we can not guarantee its safety and reliability. So it is very important that whether the security and control system of aircrafts can work properly. The security control detect card is developed as an special equipment for aircrafts’security control system test. Its main function is testing whether the aircrafts’security control system are working properly.The IPC communicates with the board through CPCI bus interface with the friendly man-machine interface. We can use the man-machine interface to set the send parameters and display the send result. The board completes the modulation and demodulation twice of the instruction code and it can transmit and receive the modulating signal. The demodulated instruction code will be compared with what set in the test software. The device have self-test function and can use after installing the driver and inserting to the IPC with CPCI slots.We use the PCI9054chip as the signal bridge between the IPC and board. The PCI9054works in slave mode. We get the control logic of local bus interface in FPGA with verilog. The DBPSK modulation and demodulation of instruction code are accomplished in FPGA chip EP1C20F324I7which has rich resource and feature of flexible EP1C20F324I7is also used to configure the LO chip in the RF circuit. At last, the result of whole test indicates that all technique data have meet the demand of system. The product has been delivered to user.
