An AMR(Automatic Meter Reading) system is used to automatically collect data from meters. In this paper we design and implement a Wireless Automatic Meter Reading System to solve the problem in existing AMR system. The system consists of wireless modules, measure meters and management center. A general wireless module, is developed to transfer the data(More)
As a unified modeling simulation language for complex multi-domain physical system, now Modelica is getting more and more attention, and its compiler and solver method emerges in endlessly. However, up to now little solver method consider the efficiency of repeatedly simulation after modifying variable parameters. Here, a method focuses on improving the(More)
—UP to now, it has become a big problem for most Institutions of higher learning in the experimental teaching of Industrial Engineering specialty for many apparent reasons, such as too expensive to buy logistics devices, update speed of devices getting faster and faster, too large bulk of devices to find an indoor place to settle them and so on. Therefore,(More)
