In view of low level of greenhouse automatic control system in China at present, this paper introduces a agriculture greenhouse environment monitoring system based on ZigBee technology, then gives the overall design of physical structure of system, network topology and its hardware and software designed of the composed modules. The PC software develop with Visual C++6.0 and SQL Server2000 that provides...
Based on the analysis of the development of agricultural mechanization, the trend of agricultural service system reform, agricultural environment protection and the development of information technology, it is possible to realize the precision agriculture. This paper designs the agricultural environmental monitoring system based on the wireless sensor network (WSN). The system can real-timely monitor...
In view of the importance of water quality in Aquaculture, this paper designs an environmental factors monitoring system. The whole system is comprised of two parts: one is PC, which acts as a host computer; the other one is a slave computer, whose core is AT89S51 microcontroller. Slave computer has data collecting module, data storing module, control module, power module, display module, etc. The...
Nowadays, with rapid development and higher technology in portable computer development. Computer widely used to control machine and other electrical component. With availability of new software and hardware that can easily bought in the market, user will chose the software or hardware with the easiest and interactive way for control and monitoring purpose. This paper present prototype of educational...
ZigBee wireless sensor network usually works in a complex environment, and the energy of sensor node is very limited, so energy consumption is a big problem in ZigBee wireless sensor network,especially in the multi-sensor system. Plant eco-physiological monitoring system is a typical multi-sensor system. There are many kinds of sensors in this system. These sensors, as well as ZigBee module and some...
The embedded elevator monitor system (EEMS) based on wireless communication is introduced in this paper, which includes the overall system architecture, hardware and software structure. The EEMS based on wireless communication adopts and Linux system which is powerful open source operating system. S3C2440 microprocessor is used as the EEMS main controller's CPU. Meanwhile the whole information flow...
In some oil fields, the consumption of electricity and energy was very high because the beam pumping unit worked sustained, expect in the height period of electricity consumption. It increases the burden on the grid and make machines wearied easily when voltage instability. In this paper, we propose a concept of intermittent pumping to beam pumping unit and build a monitoring system of oil wells based...
In the past, the managers of the electric power department know the situation whether electric power network works well, by recording all kinds of monitoring data artificially, or setting some observations for video surveillance with the aid of ISDN. While video surveillance has a lot of advantages, there are still many inadequacies, such as, requiring complex digital terminal, responding slowly,...
An on-line monitoring system of contact temperature inside HV switchgear cabinet based on Zigbee has been studied and developed, which consists of the power monitoring center, the temperature monitoring unit and the temperature display unit. The contact temperature of switchgear is measured by DS18B20 of the temperature monitoring center which is designed based on CC2430, which is timely sent to the...
This paper presents a wireless intelligent incontinence management system being developed for the University Malaya Medical Center (UMMC) that utilizes ldquosmartrdquo diapers to discreetly monitor and estimate wetness events, detect other relevant clinical conditions and alert staff by transmitting information via wireless technology to an intelligent central management system. We describe the hardware...
