The Implementation of Embedded DTU Access Management Server
Abstract:DTU access management server (DAS) is a server that manages registration, online message, receiveing and single sending or group sending data of DTU. DAS is a reliable bridge between DTU and upper application software which can quicken the development of application system and to accelerate the accomplishment of serial devices wireless, mobile access. This paper introduces a method based on GPRS DTU and DAS, and gives the design and realization of hardware and software.
