Abstract: This article introduces a negative temperature coefficient by NTC thermistor temperature sensor to the temperature protection device. Thermistor connected in series with potential, according to the RT thermistor of setting up the potential for size. When the temperature is over SCR set the upper limit of temperature, thermal resistance of the pressure will be less than the value of the series and its potential value of pressure, voltage output compared to a low on-optocoupler . Optocoupler the input signal all the way to generate more than 555 chip harmonic oscillation drive alarm warning lights. Another signal comparison circuit after 4511 to enter in the code decoder decoding the digital display driver SCR high temperature of Lu Shu. If the temperature of the first road SCR overheating of the digital display "1" if the temperature of the second road SCR overheating of the digital display "2" if first and second road SCR Road at the same time the temperature of the overheated digital display "3." All the way to signal to enter the triode transistor base-on to drive the relay, the relay will cut off the absorption into a phase of the power and activate the voice chip's power. A voice chip, after a "temperature alarm," the voice prompts to achieve this temperature protection purposes.

In this paper, we designed a building security subsystem. The program according to "multiple preventive system" design, community perimeter of the region the focus of the site, buildings and household interior, respectively, set the appropriate technology to guard against the system.
The system has perimeter guard system, CCTV monitoring system, building a visitor non-visual intercom system, home security alarm system, off-line type patrol management system, composed of community security center room.
Perimeter Protection System at community perimeter wall using active infrared mode for shooting the police; office building entrances, community entrances, garage entrances, building entrances and other key parts of unit color television monitor mode; buildings visitors intercom system interconnection way to achieve the building intercom, electric control lock, two-way calling features such as; home security alarm system is mainly based on all households in an emergency alarm button, the bottom of the residential, two-story windows and doors installed magnetic, passive infrared detectors and other alarm devices, all alarm signals are transmitted using network forms of property management; Patrol Patrol optional offline-based management system.
Because of the content of Security Systems and more miscellaneous, Designed To avoid confusion caused by too long, where only the selected anti-theft perimeter alarm system and building intercom system to do these two parts in detail.
Keywords: building security to guard against multiple subsystems

The sharing of information resource is the focus topic of library science, and information sharing between libraries is the important symbol to measure the level of national library development. Under the circumstance of network, the libraries in our country not only face the conflict between information growth and shortage of funds, but also generally encounter the contradiction between information demand and lacking of information. So the building of the system of information sharing in libraries is the only way to promote the development of libraries. Mainly from the aspects of consciousness change of traditional resource sharing, the resource repetition construction, the lacking of funds, the lacking of authoritative coordination mechanism between libraries and the lacking of planning and coordination in database construction, the paper analyzes the problems existed in sharing of library information resources under the environment of network and puts forward some related measures that should be adopted.。

Network protection to protect network and its equipment, appreciating their importance and technical characteristics of scientific research, design, operation and dispatching departments. Grid structure, network operation mode, the system failure form and abnormal way change multiterminal, for quick, reliable and selective fault and termination of the abnormal state power, long-term since, research and production of various line protection, busbar protection and automatic reclosing and frequency automatic solutions, reducing load device list, meet the demand for electric power grid, the support, play an important role. This study is about 220KV power of relay protection, the master and consolidate the design of power system protection of related professional knowledge, be familiar with the theory of power system protection design steps and design skills, according to the technical standard, the selection and configuration of the relay protection, the correctness of the selection and training in engineering practice application ability, innovation ability and the ability to work independently.
The design is based on guangxi university undergraduate and graduate institute of electrical up the graduation design. The design of the main content is 220KV power relay protection and the setting, because all sorts of relay protection, adapt to the changes in power system operation ability is limited, relay protection setting both their skill and relay protection configuration and selection problem, therefore, to relay protection setting schemes with different will have different protection effect, how to determine the optimal solution, the work will be engaged in the protection of engineering and technical personnel of research.

E-commerce is simple, fast and low cost of electronic communication, both parties not met for various business activities. E-commerce can through a variety of electronic communication mode. By 2010, customer service, marketing, establish public services for the clients through word-of-mouth marketing, or make good service brand, attract many commodities, there is needed in the service, the service is good, should be a strong competition conditions. About B2C, popular is an enterprise to individual business model, and the rise of the Internet at present a lot of use of e-commerce sites such as: sales of consumer electronics appliances products, new egg, is in the jingdong daily life and the consumption of library website, have outstanding. CRM although just "e-commerce", but it is a subset of the customers on the core position, it is "new economy", "customize" the characteristics of the batch. Through the implementation of CRM, the enterprise must fill in the past, "homework" -- it requires more understanding and potential customers requirements, existing enterprise can accurately and timely judge competition behavior, requests the enterprise can reach catch the information technology, especially the changing requirements of enterprise internal management can adapt to these changes. "Detail decides success or failure" is a classic statements on the mall in modern enterprises, if the product, service and management of the details such differences to smile whole market, may make a big difference.。
