I. Overview

With the rapid development of Internet technology and information communication technology, the wave of informatization and intelligence is sweeping every corner of the world . The rise of intelligent and digital homes has adapted to social informatization and economic internationalization. Intelligent building communities have become the leading direction of real estate investment and development. Due to the continuous improvement of people's living standards , more and more attention is paid to the quality, safety and information acquisition and management of residential quarters, which has greatly promoted the development of intelligent digital homes .

The irreplaceable role played by intelligent communities in community property management and the application of smart homes in construction, decoration and life have become an unstoppable historical trend! This trend gave birth to the rapid development of the digital community system.

At present, most of the domestic smart communities are mainly based on simulation technology. Although many smart subsystems are also configured, due to the limitations of simulation technology, there is no good integration between the subsystems, and the application of the subsystem itself is also There are big shortcomings, and the intelligent system inside the home is limited to very basic functions . Digital cell system is in digital technology, broadband network as the core, highly integrated community intelligence platform as a carrier, the family unit , subject to the overall community to achieve a modern residential area a variety of digital applications . " Digital technology community " in the existing " intelligence community " based on the full import of digital technology and information technology to dramatically improve the intelligence level of the cell, the real digital life of the family. Digital technologycomprise cell security, Internet applications and property management automation applications . In the digital cell system, when performing functional design, technical route selection, and equipment configuration, the functional requirements must be determined by market positioning, and follow the principle of"technology and function matching, equipment and technology matching, equipment and equipment matching", from economy and reliability Comprehensive evaluation of products in terms of nature, openness, scalability and sustainability, abandoning concepts and hype, focusing on practicality, allowing owners to truly experience the “digital and networked” lifestyle of the times, and also for property management The department feels a very real "integrated and automated " management method.

2. The development history of the building intercom system

China building intercom industry to the present, from the time roughly experienced the following three stages:

1. The first stage of the development of building intercom: (4+N type)

Early building intercom system products have a single function. The system only uses code-sending and decoding circuits or RS-458 to communicate in a single building in a small area, which cannot achieve large-area networking in the entire community. This kind of decentralized control system is incompatible with each other and is independent of each other. It mainly implements simple single-user and unit-type building intercom products, which is not conducive to the unified management of the community.

2, building intercom development of two phases: bus

With the development of technology and the improvement of the living standards of the Chinese people, the demand for them is gradually increasing. The original non-networking and non-visual requirements can no longer meet the needs of people, so it enters the networking stage. After 1998, networking has become the most basic requirement for intelligent buildings. The control network technology of the community widely adopts the field bus technology of single-chip microcomputer technology. Such as CAN, BACNET, LONWORKS and domestic AJB-BUS, WE-BUS and some buses realized by RS-485 technology. The use of fieldbus technology can interconnect, network, manage, and coordinate the various scattered systems in the community, thereby forming a relatively large regional system. The application of fieldbus technology in the community has made the intercom system a big step forward. Building intercom products have entered the second stage of rapid development, and large-scale community networking and comprehensive intelligent building intercom equipment have begun to emerge. However, from the perspective of the demand market, the product has entered the demand platform area. After a large number of applications, the traditional bus video intercom system also shows certain limitations:

(1) Single function, most products are limited to functions such as calling and unlocking, and the equipment utilization rate is low;

(2) The anti-interference ability is poor, and the sound or image is often disturbed and unclear;

(3) The transmission distance is limited, and a video amplifier needs to be added when the distance is long. It is difficult to connect to the network when the community is large, and the cost is high;

(4) Due to technical limitations, product upgrades or expansion of functions are difficult.

To 2000, the introduction of network video intercom systems, digital control signal using cable transmission, coaxial cable transmission of audio and video intercom systems, requiring two wire gauge. This system breaks the traditional bus structure and provides a feasibility testimony for the transition of the building intercom system to the digital stage. Therefore, it belongs to the 2.5 generation product.

3, building intercom development of three phases: TCP / IP networking type

With the popularization of Internet applications and the narrative development of computer technology, people's work and life have undergone great changes. The concept of digital and intelligent communities has been accepted by more and more people, and building intercom products have entered the third In the stage of rapid development, multi-functional intercom equipment began to emerge. Local area network technology development products based on ARM or DSP technology are gradually launched, and digital intercom technology has a breakthrough development! Using the network to transmit data obscures the concept of distance and breaks through the traditional concept. Integrate the security system into the equipment to improve the practicability of the equipment.

(1) Suitable for complex, large-scale and ultra-large-scale community networking requirements;

(2) The digital indoor unit realizes the transmission of digital, voice, and image through a network cable, which eliminates the need for data bus, audio cable and video cable. Just connect the digital indoor phone to the indoor information point;

(3) It can realize multi-channel intercommunication at the same time, without the phenomenon of busy;

(4) It has a great impact on the mid-to-high-end market of the industry and can develop across industries;

(5) The cost of setting up a network is low, which is easy to upgrade and expand;

(6) Easy maintenance and product upgrades.
