| The traditional military vehicular indicating meters, which just indicate the status of the vehicle's engine and assistant devices, can not afford too much information. Along with the military vehicles'development and the mode of war's evolvement, these traditional meters can not fulfill the modern information war's requirement any more. A kind of high-powered digital instrument, which has many functions and can afford a lot of information, should be developed as soon as possible.The Camion Integrated Indicating System (CIIS) is such a high-performance and multifunctional digital instrument. Through its clear and colorful display on wide flat screen, camion drivers can get much information easily. They can not only know various parameters, but also be warned whenever there is a parameter exceeding its threshold. The digital map and position information are also afforded by CIIS to help drivers understand the battle environment. The CIIS has black-box function too.The CIIS is actually an embedded computing system. It uses micro processor MPC8260 as central processing unit. The peripheral circuit is composed of memorys, display controller, transceiver components, etc. The driving parameters and digital map are displayed on the wide flat screen separately, switched by keys. The display controller, based on Programmable Logic Device, is designed by author. Utilizing a First In First Out memory settled in the PLD, the display controller could make the display refreshing smoothly. The operating system used in CIIS is VxWorks, based on which the device drivers and applications are designed. The CIIS developing process is full of reliability design concepts, that makes the final product reliable, anti-atrocious environment, anti-shaking, and electro magnetic compatible.The CIIS has been developed successfully, satisfying both of the function and performance requirements. This success provides a reference for modern military indicating instrument design. |
