Laser Threat Warning To Install The Design And Implementation Of The Usb Communication Interface

In present weapon platform, a laser warning device is act as a danger sensor in the self-protective system of the weapon platform. The laser warning device shares the screen with central controller of the self-protective system and works under the control of the central controller. Before the laser warning device is delivered to take system debug, it needs a personal computer to replace the central controller. This computer is used to control the laser warning device to implement its debugging and testing. Because different weapon platform needs different communication interface between the laser warning device and the central controller, in order to implementing the device's debugging and testing conveniently, we use Universal Serial Bus technology to achieve this communication interface. The laser warning device attaches to the USB through the USB port on the personal computer. When the operator wants to debug and test the laser warning device in the laboratory, he or she presses a button of the GUI to send a control order. The laser warning device receives this control order, and then enters into the corresponding work status. Finally, the data of this debugging and testing will registered on the GUI.Firstly, this thesis describes the communication pattern of the laser warning device. According to the needs to debug and test the device in laboratory, I bring up a scheme for adding a USB communication interface module in the laser warning device. Then I describe how to design and implement this module. The module uses the EZ-USB FX series chipset made by CYPRESS as the central component. I give the technique details of the module hardware design, firmware design and software design in the host side. I also describe how to debug and test this module.This scheme will not only simplify work during debugging and testing the laser warning device in laboratory, and improve work efficiency, but also have nothing to do with the communication interface defined by the self-protective system of the weapon platform.
