Abstract: In order to solve the problem of the hand module’s online temperature measurement in Nitrile glove production line process, we have developed a set of moving objects or device used for online temperature measurement. The device is mounted infrared temperature sensor, by using PLC-controlled synchronous tracking technology it can track the hand module in the production line, so it can ensure the infrared temperature sensor and hand module synchronously measure its temperature correctly. By using configuration software kingview, we have developed mold temperature monitoring online measurement interface, real-time monitoring of the mold temperature opponents. After analysis of experimental results we concluded that the device work stable, acquisition of temperature reliably, so it has a promotional value.

Abstract: Due to the existence of different grades of mineral in the mining area, the technology of slurry pipeline grade transmission is developing. However, the process of grade transmission will appear the phenomenon that the slurry of different grades are mixed. Therefore, before cutting into different grade slurry, we added special medium in pipeline to separate different grades of slurry. We worked out slurry pipeline transport model by mathematical modeling and building slurry pipeline transport real-time location tracking system. The system was able to distinguish different grades of slurry by adding special medium and tracking the actual location of the head and tail of slurry, realizing real-time position monitoring of different grade slurry.

Abstract: J2EE is set for the distributed computing realization of API, services and protocols developed by SUN. The design objective of J2EE computer development tool is to provide a simple, easy operation development platform for developers, which can reduce the cost of development, shorten the development cycle, and improve the comprehensive performance of computer system. In this paper, we use JSP calculation vessel function module of J2EE to improve the computer economic detection system, and establish data connection between system and the HTML Webpage, which realizes the real-time and continuous detection of the economy. Finally, based on the external demand and exports of industrial products in an area, we detect trade transactions in the region, and do mathematical statistics using the J2EE system, and finally get the trade scale. It provides a new computer method for the research of export trade and economic detection.

Abstract: In order to realize the real-time monitoring of crop growth environment, this paper applied the Java JDK 6 + Eclipse 3.5, developed agricultural remote data collection system based on zigbee, greenhouse planting of crops growth environment parameters, such as air temperature, humidity and so on, with all kinds of sensor dynamic collection, and transmitted to the user through the network client terminal. This makes agricultural personnel through the terminal computer real time control of the growth environment of crops, can take timely control measures, has realized the remote, multiobjective agricultural information, the parameters of the real-time acquisition, display, storage, query, statistics, and other functions, provides a effective way for the agricultural informatization construction.

Abstract: This paper presents a case study for the design and implementation of real-time harmonic monitoring at the main 3-phase 4-wire distribution system in a shopping center. The implemented monitoring system automatically acquires real-time data from a power-quality measuring instrument over Ethernet connection. The acquired data are subsequently stored in a database and can be retrieved for further processing and analysis. As a result, harmonic currents of all three phases and a neutral can be monitor up to 31^st order.

Abstract: Risk prevention of historical buildings through sensor network monitoring represents a challenging and together promising task towards an optimized buildings’ protection plan. Due to the significant character that historical buildings have within the history and identity of local and consequently national communities, the monitoring approach above is nowadays considered a fundamental component of cultural preservation. Modern trends on sensor networks nowadays allow the installation of wireless monitoring equipment, able to collect a large volume and variety of data that can be further processed in order to support prevention modelling techniques and strategies. Despite the valuable post-processing outcome of the above modelling techniques, in several real-time monitoring cases, an aspect that may significant impact the data analysis accuracy from the monitoring engineer is to create an audiovisual representation of the gathered data that are easily perceived and directly associated to well-known environmental conditions. Towards this aim, in this work an audio-based representation of the collected data is introduced that achieves high monitoring performance in terms of the perceived nature of the building vibrations themselves. The proposed audio-based representation technique is based on a number of advanced sonification methods, combined with specific human-hearing simulation mechanisms that allow an effective increase of the represented information volume in real-time. A number of subjective tests that were performed demonstrate a significant improvement on the way that the monitoring personnel can efficiently perceive the origin and / or nature of the acquired vibrations, rendering the proposed technique a strong supplement towards efficient historical building risk prevention.

Abstract: The traditional temperature and humidity monitoring system of grain depot used to realize in wired network which needs to deploy a large number of cables. The maintainability and scalability is poor. We present a solution of monitoring temperature and humidity of grain depot based on wireless sensor network (WSN). The temperature and humidity data acquisition and control node is composed of digital temperature and humidity sensor and RF wireless chip and the main control chip. Based on the Zigbee technology, these nodes construct a WSN in Ad Hoc in order to collect, monitor and control the temperature and humidity in the monitoring area. The convergence node in the WSN will packed acquisition data from other nodes and then transmit them to a remote monitoring host through the GPRS wireless mobile network. By means of the statistical analysis of the real-time data collected, the monitoring host can alarm and feedback control the temperature and humidity of grain depot. The experimental results show that the system has strong scalability, low power consumption and high efficiency.

Abstract: This research described in the paper proposed a device combining wireless sensor technique, GPS and wireless charge technique. This device can be installed nearby the vehicle tailpipe and transmit measurement data of exhaust gas to the backend system in real-time. It facilitates knowledge of exhaust gas the vehicle generated on the route it passed. With this information, a reference system is developed to estimate gas pollution that will be generated by the vehicle on each route. An artificial intelligent method, case-based reasoning is applied in the system design. Meanwhile, a new mathematical model can be built with additional consideration for gas pollution in route planning and optimization of vehicles. Some optimization approaches, including genetic algorithm, and some other combination algorithm can be applied to get solution of this model with new additional constraints.
