Second, the design goals
2.1 The overall goal of intelligent construction
Through the use of modern information transmission technology, network technology and information integration technology, precision design, optimized integration, and meticulous construction, gradually establish a multimedia integrated information interaction system that communicates with residential and households, household and community integrated service centers, households and external society. Provide residents with a safe, comfortable, convenient, energy-saving and efficient living environment. Combining the development characteristics of the information industry, aiming at the requirements of broadband multimedia information interaction in the 21st century, fully consider the scalability, highlight the forward-looking nature of the solution, and ensure that the intelligent system has certain manageability, scalability and Maintenance.
2.2 The guiding ideology of intelligent construction
Adopting advanced concepts, technologies and methods, paying attention to the relative maturity of structures, equipment and tools, not only reflecting today's advanced level, but also ensuring that it will dominate in the next few years, while adhering to application-oriented, practical, and adhering to practical and economic principles. Focus on the collaborative operation of selected technologies and equipment, protect the long-term effects of system investment, and the ever-expanding needs of system functions to ensure the openness and standardization of the system. In order to adapt to the requirements of system changes, we should fully consider the simplest method and the lowest investment to realize the expansion and maintenance of the system, thus effectively protecting the initial investment of the owner and highlighting the economics of the program.
Adhere to a high starting point, make full use of today's advanced and mature intelligent technology to ensure the advanced nature of the system in a certain period of time; adhere to "practical, reliable, advanced, and economic" to ensure system integration, overall optimization, safety and reliability, and steady advancement .
Third, system design principles
Intelligent community system engineering should follow the following design principles in the design process of this case:
1. Feasibility and adaptability
The system must guarantee technical feasibility and economic possibilities. Today's technology is developing rapidly, and the technologies and products that can be applied to residential communities are endless. The systems and products designed and selected should enable users or Party A to benefit tangibly and meet the needs of recent use and long-term development. Among the various ways to achieve information, choose the most economical and feasible technology and methods. Designed with existing mature technologies and products, taking into account the current situation and development trend of the surrounding information and communication environment, and taking into account the requirements of the management department, the system design scheme is feasible.
2. Advanced and mature
The system design must consider the advanced nature of the system, but also pay attention to the stability and reliability of the system. The design of the system should have high reliability, ensure the accuracy, integrity and consistency of the data after the system failure causes the system, and have the function of rapid recovery. Especially in important systems, high redundancy should be ensured to ensure that the system can operate normally.
3. Openness and standardness
In order to meet the coordinated operation of the technology and equipment selected by the system, as well as the long-term effects of system investment and the expansion of system functions, the system design must adhere to the openness and standardization of the system. The openness of the system has become a direction of today's system development. The more open the system, the more the system integrator can meet the user's design requirements for the system, and it can reflect the principles of science, convenience, economy and practicality. Standardization is an inevitable trend in the development of science and technology. Under the possible conditions, the products used in the system are standardized and generalized as much as possible, and the internationally accepted standards or protocols are implemented, so that the products selected by them are highly interchangeable. .
4. Reliability and stability
The system design must consider the advanced nature of the system, but also pay attention to the stability and reliability of the system. The system should be designed with high reliability to ensure the accuracy, completeness and consistency of the data after system failure or system failure, and to have a quick recovery function. Especially in important systems, high redundancy should be ensured to ensure that the system can operate normally.
Fourth, the system introduction
4.1 System Introduction
Although the first generation of intelligent gateway system of Bochuang realized a unified platform for smart home and intercom, security and access control systems, since the intercom system still uses analog technology, it is still necessary to lay two sets of wires in the wiring construction. Moreover, due to the complexity of the networked devices in the analog intercom, it is impossible to solve the problems of device preemption and long-distance signal attenuation. Therefore, after more than two years of research and development, the technicians of Bochuang Company have developed a new generation of smart home gateway based on all-digital transmission.
The new generation of smart home gateways truly achieves a single line access, which not only solves the problems that the previous generation gateway can't solve, but also greatly enriches the functions of smart homes:
4.2 Outstanding advantages of the system
4.2.1. Simple and flexible networking
The cell network is a service network superimposed on the existing cell broadband data transmission network, and the transmission request is proposed to the broadband data transmission network, and the bearer network is not separately constructed.
4.2.2, suitable for networking in large communities and complex environments
For large-scale communities or large-scale villas with complex environments, traditional bus intercom systems are prone to signal transmission quality problems when networked, especially for video networking. Bus intercom systems need to add video relay equipment, which is easy to cause signal attenuation and affect video. Quality, at the same time, causes great difficulties in construction and maintenance; using Bochuang's all-digital gateway, various signals are transmitted digitally through the TCP/IP protocol, without the need to add repeaters and other equipment, and the signal quality is stable and reliable.
4.2.3, overcome the busy problem
Overcoming the busy problem of the bus intercom system, the Bochuang all-digital gateway system adopts a star network structure, and realizes point-to-point calls through TCP/IP network transmission, and calls between users are not busy.
4.2.4, using standard interfaces
The system equipment only needs the door machine, the indoor extension and the management center, and does not need the interlayer equipment such as the isolator and the network switcher. The equipment is simple and clear, and the installation is simple, which greatly reduces the construction difficulty and the equipment failure rate. With network cabling, it is also possible to share the network with the computer without separate wiring, which reduces the engineering cost and reduces the construction cost to almost zero. All equipment uses an international standard interface for easy maintenance, maintenance and expansion.
4.3 main functions of the system
