1, the hardware platform's processing capabilities are increasing
The early intelligent controller used 8-bit microcontroller as the core processing unit, the function is relatively simple and pure. Often only security, three-table acquisition, simple text information distribution and simple home appliance control functions. In this period, the product operation interface was relatively simple, and advanced functions such as home appliance control were limited to display concepts. In recent years, many manufacturers have adopted more powerful single-chip microcomputers or use multiple single-chip microcomputers to work together in order to make their products more comprehensive and beautiful. The product operation interface during this period has been greatly improved, often using color LCDs, mostly with touch functions, integrated building intercom functions, and home appliance control functions are also relatively abundant. At present, some manufacturers use 32-bit processors, combined with advanced embedded development platform to develop more advanced products. The product processing capability based on this technology has been significantly improved. In the past, multimedia information and value-added services that could not be processed have been realized. Due to the use of a dedicated display engine, the interface is more plentiful and beautiful, and the home appliance control functions tend to be perfect.
2. Subsystems such as security intercom increasingly become an integrated platform
The initial intelligent central controllers are often independent of traditional security and intercom systems. The user's home needs to install several sets of independent subsystems, which increases the complexity of installation and use. The integration of technologies between industries has promoted the smart home platform to become an intelligent home platform that includes security, intercom, information, and home appliances to control home digital audio and video.
3, the gradual transition from analog to digital
Just like the gradual transition of analog TVs to digital TVs, analog handsets and digital handsets, the smart home platform is also undergoing a transformation from analog to digital. Digital technology is increasingly applied to smart home systems, mainly in the following aspects: First, more and more digital integrated circuits are used in circuit design. In today's smart home products, a large number of digital chips are used, and the degree of integration and reliability have been greatly improved over the previous analog circuits. Second, the digital display has greatly improved the display effect. In addition, the transmission mode gradually moves toward multi-network integration. Security, intercom, and access control meter reading gradually lead to a unified Ethernet connection. Multi-network integration will greatly reduce the complexity of construction and maintenance, and increase the transmission reliability.
4, from cable to wireless
Wireless transmission features are flexible. Mobility and scalability are not available with wired transmission methods. But the wireless technology needs to solve many problems. For example, how to make the transmission distance as far as possible, but as far as possible to avoid damage to people 7 how to avoid signal interference? How to increase the transmission bandwidth so that more complex data can be transmitted and so on. Although these problems require technical R&D personnel to constantly delve into innovations, it is believed that the overall trend from wireline to wireless cannot be reversed.
5, in the control technology into the family
In the past, high-end smart central control was mainly used in the field of professional conferences. With the continuous advancement of technology, increase in product categories and reduction of production costs, smart centralized control systems have been applied to the smart home sector and have begun to enter millions of households. . The application of control technology in smart homes is mainly towards more convenient, faster, safer and smarter. The specific control functions and equipment components of the smart home control system mainly include intelligent centralized control of a series of home control systems, including environmental lighting systems, home theater audio and video systems, security monitoring systems, public broadcasting/background music systems, air conditioning systems, electric curtains, etc. .
In the aspect of home appliance integration, the central control technology can learn the infrared codes emitted by the home appliance remote controllers to the central control host, and then write programs and interfaces so that infrared commands can be invoked and transmitted to realize the television through the touch screen. The control of similar household appliances such as machines and other remote controls; in terms of lighting systems, what Zhongguan has to do is to control the relay according to the control protocol of the relay and the dimmer box so as to realize the control of lighting; more professional equipment such as projectors The manufacturer will provide a control serial port and provide a special control protocol so that the central control host can be connected to the control serial port of the device, and the projector can be controlled according to the instruction format provided by the protocol.
