Abstract: A neonatal nursing information system based on Internet of things is proposed, according to the situation of neonatal nursing in the hospital. The system is a complex application making use of RFID, sensors, Zigbee, Wi-Fi and other technologies, which includes three sections: environmental monitoring of neonatal wards, neonatal information management, and traceability of neonatal information. The application of the system can reduce medical errors, avoid medical risks, and realize scientific management. It improves the level of management in the hospital.

Abstract: Employment management information system based on new technology provides good support for college employment management. On the basis of analysis of C / S or B / S architectures, the design of employment management information system with WebService is proposed. Analyze needs from the two aspects of system performance and functions. Build three-tier structure including data layer, business logic layer and presentation layer. Optimize system safety performance and data transfer performance by means of double-encrypted methods and compressing data with serialization. Optimized design of employment management information system can effectively improve the efficiency of university employment management work and provide a reference for the design of other management information systems.

Abstract: The network communication between MATLAB and configuration software is established using DDE(Dynamic Data Exchange) technology, which is easily to give full play to generate interactive interface in configuration software and simulation of control object model in MATLAB software. The calculation function of weakness in configuration software is repaired and the control object model and controller is to be isolated. The effective simulation platform for theory research and design of control system is established.

Abstract: Hardware connection and software implementation of communication are designed between the S7-200 PLC and Ethernet. Hardware composition is introduced and low-power microprocessor S3C2440 is selected as the control chip, DM9000 as Ethernet control chip, serial port RS-232 as testing interface. Monitoring page is designed to show the status of PLC. PPI protocol is known by analysing the communication process of S7-200 with PC. Embedded web server Boa is transplanted and CGI program is developed in Linux embedded operating system. It can realize the function of reading and writing I/O value and simulation value. The experiment shows that the system can realize reliable serial communication. It brings a great convenience to work.

Abstract: For the phenomenon of the college laboratory equipment mismanagement recent years, the RFID/ZigBee-based laboratory equipment remote management solution has been proposed. The hardware uses a ZigBee wireless network chip, an MSP430 low-power data processing chip and a WiFi data transmission module as the core, combined with various sensor and RFID technologies to perform information collection and transmission. The software is a web server developed in C# platform, using a three-tier structure to perform data storage, data access, and data processing. The experiments showed that it can perform communication between a monitoring terminal and a laboratory device timely and accurately, and achieve client integrate, and improve the efficiency of managing the laboratory equipment.

Abstract: Based on human and computer understanding, the paper proposes two web information resources sharing modes. The first mode consists of explicit and implicit information resources sharing, and the second mode is an intelligent style established on semantic web. Thematic database resources building and large authoritative websites building are two kinds of the explicit information sharing. Blog and professional forum, the typical representatives of the Web 2.0, has a good effect on the sharing of implicit information.

Abstract: For high bit-rate optical communications system, the changes in temperature or power fluctuations are due to the dispersion of the dispersion tolerance than the system. Therefore, the dispersion compensation unit must have the functionality to adapt to the dynamic generation of tunable optical communication network development. This article describes several dynamic tunable compensation techniques and the basic principles of the performance characteristics of the situation at home and abroad, including the chirped fiber grating method, the virtual image phased array method, GT interferometer method, the array method and the planar waveguide grating method, and a brief discussion of tunable dispersion compensation technology in the future direction of development.

Abstract: Motor in a variety of electrical transmission and position servo system occupies an extremely important position. After the DSP technology being applied to the motor control, the unification of the hardware and the flexibility of the software can be combined. Take the brushless DC motor for example, obtained the design scheme of the DSP-based asynchronous motor control system. With its 32 bit fixed point DSPTMS320F2812 as the core design of the hardware system, we wrote the system software, debug the motor control system and the results show that the system achieves the expected effect. The results of the research can be applied to brushless DC motor and other motor control, it will have a wide application prospects.

Abstract: As a focus for the current research in the informatization field, Interactive Electronic Technical Manuals (IETMs) involve all kinds of activities relating to equipment support and diversified extensible interactive interfaces. By studying the interaction of IETMs for aviation equipments with other information systems, IETMs functions can be expanded in terms of maintenance aiding, training aiding and technical data management aiding. By creating an integrated data environment framework of IETMs for aviation equipments with Extensible Markup Language (XML) technology, an intermediate mode, the information exchange and sharing can be achieved between different data sources, and the supportability and supporting capability of aviation equipments can be improved.

Abstract: The system uses the latest computer and RFSN induction smart card technology, with the principles of scientific, advanced, reliable and economy, and it is developed on the basis of many factors. Installing a set of import and export management facilities on the Entrances and exits of the parking lot, parking spaces will form a relatively closed space. When the vehicle is entering or exiting, the system captures images and recognizes vehicle license automatically etc,to make video surveillance of vehicles, real-time recording Vehicle access images, accounting, and so forth. It will be an effective work to control, monitor, and manage parking lot, reducing the operating costs of the parking lot, and to prevent steal vehicle behavior, which protects the interests of management and owners.
