This paper introduce a new type wireless monitor system which applied in industrial field. In the system, the main hardware includes the S3C2410 microprocessor in ARM920T core, and the software adopts Linux which is an embedded operating system, communicate by GPRS wireless transmission service. We can get real-time video data through USB camera firstly, compress and encode it with MPEG-4, ultimately...
This article introduces a type of embedded single chip network measure and control system based on Ethernet, which adopts high speed single chip with kernel of 8052. Through controlling the special chip for Ethernet, the system realized the function of TCP/IP protocol. Since the system can be used as an independent system, any computer on the net can control the system or transmit order and data to...
One conclusion derived from practice is that the power line carrier communication is not suitable for Chinese AMRS (automatic meter reading system). Considering the rapid spread of Internet, the AMRS based on Internet is presented. The structure of system consists of server, data collectors and Internet. For a short distance transmission, data collector collects data from electricity meter using RS485...
