摘要
对基于89C51的数字化汽车仪表硬件设计进行了介绍,并给出了具体的解决方案,将仪表整体分为主控模块、传感器及信号处理模块、显示模块和电源模块等进行模块化设计。试验数据表明,系统实现了车速和油量3位显示,里程5位显示,具有稳定性好、显示直观,车辆运行安全系数高等特点。
A total solution of the digital automobile instrument was studied,which is based on 89C51. The solution uses the modular design, divides the player into the core module, the sensor and signal deal with module, the display module, the audio module,the power module etc. Test data shows that system achieves 3 bits numeric display of automobile speed and oil capacity, and 5 bits numeric display of mileage. Its characteristic is good stability, display frank, high safety factor, etc.
