This paper introduces a radioactive source tracer anti-theft system, which mainly consists of three parts-Detection probe, Tracker and PC. It is based on RFID, GSM and GPS. The system can realize non-contact information acquisition processing for the stolen radioactive source. If there is unauthorized or illegal movement of radioactive sources, GPS/GSM system which is installed in the radioactive...
Cultivation method of greenhouse is that the growth of crops doesn't depend on the nature environment and keep the best of optimization of environment by artificially controlling the environment. An Embedded systems approach to monitor green house have become quite important now a days, especially for monitoring and control of green house systems. Small green houses are typical examples. First, they...
To meet the requirements of some intelligent vehicle monitoring system, the software integrates Global Position System (GPS), Geographic Information System (GIS) and Global System for Mobile communications (GSM) in the whole. The structure, network topology, functions, main technical features and their implementation principles of the system are introduced. Then hardware design of the vehicle terminal...
Based on the background that vehicle monitoring system had urgent necessity recently, the paper put forward a overall scheme of vehicle monitoring system combining with global positioning system (GPS), global system for mobile communication (GSM) and geographical information system (GIS), introduced the key technologies of this monitoring center software, designed the function software of monitoring...
In this paper the structure and work flowchart of monitoring remote pharos system is firstly overviewed. A RTU based on dual-MCU for remotely monitoring pharos has been developed. There are three types of working mode, Polling mode, alarm mode and Calling mode. Two independent systems based on dual MCU work depending on work modes. Especially when polling mode, one system whose power consumption lower...
