With the development of modern agriculture, greenhouse environmental control technology has made great progress. But there are many shortcomings of the greenhouse environment monitoring system such as low level of automation, system design complexity, and low level of modern management. Currently, most of the greenhouse control system focused on the theme of the micro-computer field,

Along with the development of automotive electronic technology, automotive electronic control units are more and more. The communications between them are increasingly complex day by day; the traditional single point-to-point mode cannot meet the requirements of current electronic control units. Controller Area Network applied in vehicle has solved the communication problem between each control unit

In the field of industrial measurement and control,test objects are complex,test parameters are various, and it requires high standard for test speed and test precision. The traditional single-parameter and handworked tests were not suited to the development of productive forces. What’s more, some industrial field is difficult to intervene.So,it’s necessary to carry out the automatic

Wigner-Ville distribution(WVD) is widely used in the filed of signal processingduing to all kinds of excellent mathematical characteristics. However, the cross-terms ofthe WVD often bring us lots of problems, because the WVD is not additive in thecalculation. Aiming at this problem, cross-terms erasing method based on dual EnsembleEmpirical Mode Decomposition(EEMD) is put forward in this
