Based on the high level swimming teams of Tongji University This essay introduces a specific training information system used in swimming which was built by the skill of electrommunication, network communication and database technology. In this system, using the ZigBee transmission technology, a wireless real-time timer technique was adopted and communication master station was used. As a result,...
This paper introduces a data collection system that uses wireless communication components PIC16F877 and GPRS to transfer and capture the data remotely. The key data collection terminal is insisted by a micro controller named PIC16F877 which is responsible for controlling several parts such as LED screen, MC39i working in GPRS as well as various data operating modules. MC39i is responsible for sending...
At present, water quality monitoring is the essential part to our country's aquaculture. In this paper, we developed a real-time water quality environment monitoring system based on wireless sensor network to acquire data of environmental factors of water quality. Also, the system can provide expert knowledge to deal with data for making control decision. Such a system is attractive because it ensures...
Since its introduction in 1992, the Teledyne RDI Instruments (TRDI) Workhorse ADCP has become ubiquitous, with literally thousands of systems deployed in nearly every body of water on earth. While the measurement itself remains relatively unchanged, in the intervening years the use of the measurements has changed to an extraordinary extent. Originally a novel way to measure currents sorely in need...
During under-crossing shield, the monitoring of the existing tunnel has been done by the improved Georobot automatic deformation monitoring system. Results show the iron rails of existing tunnel have some regular settlement, difference settlement and lateral deformation. The vertical and lateral compressive and tensile deformation also exist in the structure of the tunnel section. The automatic deformation...
Ferroelectrets are charged polymer foams with piezoelectric effects, developed around two decades ago. Compared with ceramic piezoelectric materials, ferroelectrets have many advantages, such as flexible, light weight, low acoustic impendence, and so on, indicating a lot of potential applications. Through developing corresponding circuits, this paper provides some interesting and innovative devices,...
To achieve better monitoring for small-scaled mobile robot, a real-time status monitoring platform is developed in this paper.

In this paper we present MIRTES, a project for a data, event, and code-centric middleware with realtime characteristics targeted to wireless sensor networks. The MIRTES architecture and implementation focusing on data-centric services is here proposed together with its experimental validation. At the state of the art for data-centric middleware, packages succeed in providing a database like abstraction...
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...
Radio-frequency identification (RFID) as an emerging technology has generated enormous amount of interest in the supply chain arena to reduce product loss or shrinkage. RFID technology has been used to provide a more efficient way to identify and track items at the various stages throughout the supply chain in large retail industry. This paper describes the proof of concept of real time traceability...
This work elaborates on the topic of decision making for driverless city vehicles, particularly focusing on the aspects on how to develop a reliable approach which meets the requirements of safe city traffic. Decision making in this context refers to the problem of identifying the most appropriate driving maneuver to be performed in a given traffic situation. The overall decision making problem is...
In this paper, we propose enhanced power management techniques for low-power UWB communications. The proposed power management scheme is performed by using a real-time beacon parsing method and a time slot assignment technique based on the WiMedia MAC standard. It includes normal hibernation mode features and also includes a dynamic power management scheme using the hardware-controlled sleep mode...
In recent years, much research has been done on wireless sensor networks and sensor data fusion, however there has been limited work regarding implementation of real systems that are capable of providing a highly connected sensor network for data logging and data fusion applications. This paper describes the design and implementation of a wireless, portable, and reconfigurable sensor network framework...
