车用加热器控制器的设计

The Design of Controller of Automobile Heater

介绍了车用加热器控制器的工作原理,提出了以可编程片上系统PSoC为核心的控制器设计,在充分利用片内资源的情况下,以简单的方式完成大量的数字及模拟量的输入与输出。根据PSoC的结构特点,提出了利用硬件中断和软件查询来实现多任务的运行,完成数据的采集、处理和故障的诊断、处理以及整个控制器的运行控制,PSoC的硬件和软件设计特点及大的简化了控制器的复杂性,提高了稳定性和可靠性。

This article is about the controller of automobile heater and the application of PSoC. And article introduces the working principles, component, hardware design, software design of the controller, including inner resource, main function and design process of PSoC. The application of PSoC predigests the design of circuit, improves the stability of controller.
