基于PIC18F65K90的低功耗数字压力表设计

The design of low power digital pressure gauge based on PIC18F65K90

基于保证数字压力表工作状态稳定性的同时要提高精度的目的,另外基于进一步降低功耗的目的,在设计压力表时,除了有常规的工作模式,还采用了PIC18F65K90单片机的休眠模式增加一种低功耗模式方法,这是大部分数字压力表不具备的。主要是从硬件电路检测和软件语言调试两个方面进行,详细介绍了各个选取到的硬件器件的优点,并且通过对软件算法的描述介绍了数字压力表各个功能的实现。通过与标准压力表对比获取数据的实验,测试最终的精度以及功耗,最终结果能够达到设计目标。

To improve accuracy of the Digital pressure gauge while ensuring its stability and reducing further power consumption. In addition to the normal operating mode, it uses Low-power mode of PIC18F65K90 single chip processor with its sleep mode when designing digital pressure gauge. It is not available in general. Mainly from two aspects of hardware circuit testing and debugging software language, it introduces merits of the selected hardware devices in detail and functions of digital pressure gauge by describing the software algorithm. It is proved that these methods can achieve the expected accuracy and power through comparing with the standard gauge experiments.
