本文首先对过欠压保护器硬件进行了设计,包括电源电路、采集电路和磁保持单线圈继电器驱动电路。随后用IAR visualSTATE状态机软件对整个系统软件进行了设计,编写了输入输出相关事件和动作的API接口函数代码。IAR visualSTATE可以自行产生代码,ROM、RAM消耗量小,非常适宜嵌入式应用,开发完成后可以生成相关文档,便于日后软件维护和升级,大大缩小产品上市时间。 相似文献

Aiming at the problem of not enough influencing factors were considered in traditional methods,a much more realistic stochastic model was built.In which error corrections were introduced into the geometry-based function model,an improved least squares variance component estimation (LS-VCE) algorithm with space-for-time was used to solve the model,two sets of real GPS data were collected to evaluate the performance of the model,and with which the carrier phase integer ambiguity was solved.The experimental results show that the proposed methods are superior to the traditional methods in terms of model accuracy,model solution complexity and integer ambiguity resolution. 相似文献
