Abstract: Things of RFID-based asset management applications in the metering equipment, researching applicable to the marketing of RFID tags metering equipment, automatic identification metering equipment. Based on sensor network technology, a wireless sensor network are established in the metering equipment warehouse, working libraries and other areas so that each region and the metering device automatically perception, monitoring and recording the operation of process measuring device , strengthen out of storage management, metering equipment for the entire process of tracking. Innovative metering equipment on-site mode of operation, through handheld devices, allows the operator to automatically locate existing metering operation of equipment, a comprehensive record of on-site business information to improve business efficiency. System of things technology integration metering equipment monitoring information, will achieve metering equipment identity, authentication, monitoring, positioning and tracking, real-time monitoring metering device status, with warning alarm, query statistics functions.

Abstract: Node virtual network platform is designed and realized in allusion to node administration application scenarios in cloud computing, and distributed database and virtual network model with dynamic network features are put forward; nodes build node network through self-discovery packet and provide ability of addressing capability through built-in database engine. In the environment of super-large scale, node degree influences the whole virtual network platform. Through test, this platform can meet the needs of dynamic condition of application node brought by the explosive application request.

Abstract: The paper design intelligent monitoring system of aquaculture based on CC2530 wireless sensor networks, combined with the actual situation, takes the tilapia as an example to analyze detailed of the process in intelligent high density culture. At the same time, the paper introduced each function module of aquaculture for the intelligent monitoring system and formulate control standard according to the aquatic products in different growth stages of demand, through the real-time monitoring of aquaculture environment, measured the standard parameter setting of parameters and the system automatically adjusts the aquaculture environment comparison. The test results show that the temperature error is in the range of 0.5°C, dissolved oxygen amount of error is in the range of 0.3mg/L, the error of pH value is within 0.3, system data transmission correct rate is more than 98%.

Abstract: The monitoring system of tire pressure is regarded as a security product of a new generation of vehicles equipped with high-technology. At present the tire pressure monitoring system can not detect tire pressure all the whole time and tire malfunction can not alarm in time too, this paper proposes an intelligent tire pressure monitoring and alarming system. This paper introduces the overall structure of system and describes the implementation method of system design from two aspects of hardware and software. The system can monitor the tire condition in time and alarm for abnormal situation. It has some advantages in low power consumption, reliability and security.

Abstract: In this article apply AOP technology to multithreaded monitoring, using a database to store thread information multi-threaded monitoring platform implementation scheme, thread monitoring module is completely independent of the original system.

Abstract: Exhaust gas temperature (EGT) is an important parameter for aeroengine. By monitoring the change in trend, can effectively predict the engine take-off performance. The characteristics of takeoff EGT were introdeced firstly. Two methods of estimating takeoff performance were analyzed subsequently. According to the statistical data, EGT can be used for takeoff performance prediction.

Abstract: This system based on embedded technology, MMS wireless communication, etc. Various kinds of modern technology, design a kind of based on GPRS MMS remote monitoring alarm system, this system chooses LPC2132 chip as embedded processor, serial ports, camera, GPRS and infrared pyroelectric sensor module and other hardware. Main funtions as follows: when someone illegally broken into specific space abnormal happens, infrared pyroelectric sensor embedded processor immediately trigger caused disruption, the camera automatically shooting scene image, and transferred to the embedded processor module, embedded processor calls AT instructions through GPRS networks will the collected pictures sent to specify users mobile phone. Users can call or send messages to the system for pictures, but also through the mobile terminal control the system protection and removal. System software embedded in part using development platform ADS development, the key technology was embedded processor interrupt trigger, user instruction processing, control the acquisition and sending MMS etc. This paper analyses the working principle, AT GPRS directive system structure of use, embedded in space, thus realize user of real-time monitoring and alarm.

Abstract: Short circuit protection of high-voltage power lines in coal mine cannot realize selectivity with existing protection systems. To solve this problem, a scheme of protection and monitor underground based on PROFINET was proposed. The system is mainly composed of PROFINET network, monitor, controller, and integrated protector with PROFINET IO interface circuit. The system achieves protection and power monitoring network integration, completes the selectivity of short circuit protection, and can determine fault position quickly. Thus the troubleshooting time is cut and reliability of power supply network is improved. The simulation results show that the POROFINET real-time meets the requirement of protection and the system can realize short-circuit protection and power monitor function.

Abstract: The automatic monitoring and control method for aerosol cultivation of lettuce was proposed by real-time monitoring and automatic control of the cultivation environment, on-line detection and automatic control of nutrient solution, and the combination of field control and remote control, which has realized the intelligent management of aerosol cultivation of lettuce based on plant factory. The monitoring and control system of aerosol cultivation, the control model for the spray frequency of nutrient solution and the fuzzy control method for the pH value control of nutrient solution were introduced. The control system has been applied in the agricultural science and technology park, and the results show that the aerosol cultivation of lettuce has advantages over the traditional method.

Abstract: In order to strengthen the accuracy and stability of the measurement information, and to enhance the safe and stable operation of the new generation intelligent substation and smart grid, it studied the metering abnormal diagnosis technology, put forward the design scheme of the metering abnormal and online diagnosis system of the new generation intelligent substation, realized real-time processing of the metering abnormal and online diagnosis analysis of the abnormal reason. The analysis model for experiment was set up. The results and tests show that the metering abnormal and online diagnosis system of the new generation intelligent substation can make the real-time analysis and review, and real-time monitor the working condition of the metering system for the whole substation. The design and implementation of the system provides a good platform for realizing the reliability, stability, versatility and interconnection of the metering system of the intelligent substation. It is suitable to the construction of the new generation intelligent substation.
