In the information age of 2 1 century, the progress of human society and the development of science and technology are very rapid, and mankind has begun to enter a digital and scientific intelligent world. With the progress of human society and the rapid development of science and technology, human beings began to enter wireless city based on digitalization and networking. Wireless city embodies and adapts to the requirements of social informatization and intelligence, which is the development direction of 2 1 century housing. The new wireless city is a perfect combination of architectural art, life concept, information technology, electronic technology and other modern high technologies. Wireless city provides a safer, more comfortable, more convenient, faster and more open intelligent and information-based living space for residents. At the same time, relying on high technology, we can realize the return to the natural environment atmosphere, promote the development of excellent humanistic environment, and rely on advanced science and technology to realize the high efficiency, energy saving and environmental protection of residential property operation. The security system of villa community includes: electric sliding door and fingerprint lock system, perimeter prevention system and security 1 10 access control system, closed-circuit monitoring system, intelligent lighting control and automatic curtain system, intelligent flower spraying system, intelligent remote monitoring system, intelligent high-voltage access control system and villa visual intercom system. This design scheme only designs the villa visual intercom system for the time being. 1.2 design principles this scheme follows the following principles: advanced and practical; Simple and flexible; Reliable and stable. 1.2. 1 advanced and practical-the intelligent system design of ——XXXX villa always implements the principle of "advanced and practical". The so-called advanced means that the products and system equipment used are the application results of the most advanced computer technology in the contemporary era. Reflected in intelligence: the products and system equipment used in the system have advanced intelligent characteristics, such as self-programming, self-memory, anti-prying and anti-prying monitoring, automatic alarm, communication ability and automatic detection of equipment faults. Media: The products and system equipment used in this system adopt computer multimedia technology 2840, which has a good man-machine communication interface, which is convenient for online operators to learn and operate the system and complete various tasks. Network: In today's highly developed and widely used computer network technology, the security system of XXXX Villa will be a collection of technical defense networks. The so-called practicality means that the products and technologies adopted have passed the severe test of the market and met the needs of this system, but not flashy. The specific performance is: successful application: the products and system equipment used in the system design are mature products that have passed the market test for a certain period of time, especially in China, where there are successful application cases: the functions to be realized are reasonably configured at the time of system design, and this configuration can be changed, even after the completion of the project. Good operability: the front-end products and system software of the system have good learning and operability. Through short-term training and a little computer operation, the staff with general education level can master the operation essentials of the system and complete the duty task. 1.2.2 reliability and stability-the second principle that ——XXXX villa intelligent system must abide by is to ensure the "reliable and stable" operation of the system. This principle is embodied in: system reliability: the operation of the system requires absolute reliability. In this scheme, the configuration of front-end equipment, computer and system has been carefully considered, and all equipment has been certified for reliability. Convenient storage and recovery: In actual operation, even if the failure rate of the system is very low, there will be problems due to unexpected reasons, so the convenient storage and rapid recovery of data are fully considered in the system design. 1.2.3 Simple and flexible-even the most advanced system may fall behind with the passage of time. This system design fully considers the upgrade and maintenance of the system when selecting products and system equipment. Reflected in the following aspects: easy to upgrade: the system software can be upgraded, and the selected management software has the manufacturer's free upgrade commitment. The operation of the upgrade is simple, which can be completed only by the system administrator, without complicated operation and professional technical requirements. Modular structure: the system hardware is designed as modularized as possible, and the combination of each system is clear. All components are modular, which is more convenient for system maintenance and upgrade. Online maintenance: %D ... For the special use of this system, the work of the system cannot be stopped, so once the system stops, there will be security gaps. Therefore, the maintenance of the system must be on line 062, that is, the spare parts of the unit must be replaced without stopping the system. > >
