Temperature signal is one of the key parameters in industrial processes. Accurate and effective temperature monitoring may provide necessary device information to the operator and prevent unexpected catastrophic equipment faults due to device overheat. Compared with wired monitoring system, wireless sensor networks (WSNs) monitoring system has many advantages, such as low cost and convenient installation. This paper proposes and implements a multichannel temperature monitoring system based on WSNs module, Jennic JN5139. The hardware circuit design of the sensor node and the software design for WSNs nodes and the centralized computer using C language and LabVIEW respectively are given in detailed. An optimization subsection algorithm based on least square for thermocouple nonlinear calibration is also explored to increase the measurement accuracy. The prototype system is evaluated with an electric furnace temperature monitoring system. The experimental results show the feasibility and effectiveness of the proposed system.

New Ideas

This research proposes a novel wireless RFID-based thermal convection inclinometer. Five new ideas are presented. The first one is to make it on a flexible substrate to save more energy than the traditional silicon. The second one is to integrate both an inclinometer and a wireless RFID antenna on the same substrate, such that it becomes a wireless sensor and very convenient for usage. The third idea is to apply the hemi-cylindrical chamber instead of the previous rectangular one, so the gas distribution is more streamlined to increase the sensitivity. The fourth idea is to use a non-floating structure instead of the floating one, thus it is more simple and low cost without making a cavity in the substrate. The fifth idea is to apply stacking material for the temperature sensors, so that the sensitivities are not only larger, but the curves are more linear. Three kinds of stacking height were studied, such as 1, 1.5 and 2mm. Moreover, three types of material with different thermal conductivity are also tested, such as alumina nitride (AlN), copper and silicon. If the chamber is filled with the traditional carbon dioxide, one can see the combination of AlN/2mm is better, and the maximal linear operating range and sensitivity are 75° and 0.107°C/Degree, respectively.

Low Rate

Wireless sensor network (WSN) requires a wireless communication technology which is low in cost, low in power and easy to be implemented. IEEE802.15.4 standard is the standard specially designed for low-rate wireless personal area network (LR-WPAN) and aimed at introducing an unified standard for the low-rate interconnection between different devices used by a person or in a home, focusing on low power consumption, low-rate transmission and low cost. Since LR-WPAN which is defined on the basis of standard IEEE802.15.4 is of great similarity with WSN, it could be used as communication platform for wireless sensor. This paper, based on the analysis of LR-WPAN, puts forward the WSN networking scheme based on IEEE802.15.4.

Investigation of the stability of the building is a needed measurement process for all buildings in the cities. Periodic monitoring of the structure for such damage is therefore a key step in rationally planning the maintenance needed to guarantee an adequate level of safety and serviceability. However, in order for the installation of a permanently installed sensing system in buildings to be economically viable, the sensor modules must be wireless to reduce installation costs, must operate with a low power consumption to reduce servicing costs of replacing batteries, and use low cost sensors that can be mass produced such as MEMS sensors.

The Stability

Zigbee technology which targets low data rate, low power consumption and low cost application is suitable for Wireless Sensor Network (WSN) as its wireless communication technology. In the construction of WSN using Zigbee, the factors which could affect the stability of communication links should be considered. In this work, we discuss the construction environment of WSN. Then, in order to access the performance of Cluster-Tree network, we develop an NS2 simulator for Cluster-Tree WSN, and analysis the influence to stability of communication links caused by sending packet ratio and communication range. The simulation results show that it is not useful to improve the stability of communication links by increasing sending packet ratio and communication range simply. Both of them should be in a relatively balanced state.
