【 Weak current College 】 smart home structure introduction

Smart home do for some time, but haven't really going to write something, now some of our main products of the company's smart home, as well as the installation instructions described below:

First, the overall chart

Of course, in General before you introduce the intelligent House layout map:



Now let me introduce the network map

From network chart we can see that our system shows nine subsystem (home control including: appliance control, lighting control, curtain control if there are community; the community information service system), each subsystem is relatively independent and interconnected systems. Individual subsystems through data hosts (comparable to a PC), handled through data host or relay communication with other systems after. In the middle of the system is a major terminal controller: intelligence in the controller (the equivalent of PC Touch Panel), he issued instructions will be provided by data host processing.


Security alarm system with alarm host data via RS485 lines to host the data;


Monitoring system using video servers integrate video data attached to a LAN to upload the data to the host.


Video intercom system audio through wireless intercom switch to data host their videos through the video, in line with infrared switching matrix, video server connected to the LAN to upload it to the data, audio and video synchronization data host; in another video cable access intelligence in the controller.


Home control system via radio frequency transmitter via RS485 lines connected with data host; all home appliance controllers are receiving wireless RF's touch switch, the command signals are data host; you can also use universal direct control and not after sending data host directive.


Background music system and data communication is accomplished through a host of RF transmitter emits radio frequency signal, infrared transceiver receive RF signals and signal conversion to infrared, infrared signal sent to the music of the LCD control panel allowing the host to control music host.


Home communication system via network cable and the data is connected to the host; the main controller is PDA (handheld), smart phones.


In this way the system is connected through a host of data into a global network that enables communication between the various subsystems. Now use a table to describe the functionality of the various subsystems:



Second, the control theory


Here you should have a general understanding that our system is: through a terminal controller (smart in controller, PDA, smart phone, universal remote control) to issue control directive, through different signal data (network, 485-signal, RF signal) is transmitted to a host of data processed, then have a different signal control different devices in the home. You can figure that out:



Each appliance (controlled object) has a unique address encoding, while each action (such as on, off, play, skip, stop, etc.) also has a unique code.

Controller register appliances address coding, build controller with electrical appliances. Through the study of electrical appliances each action (such as on, off, play, skip, stop, etc.) of the code, and set up each action with electrical appliances. So when the user uses the controller on an electrical issue a control signal, corresponding to that one electric appliance can identify this controller signals, perform the appropriate action. For example: using the universal registered a band television, and through universal learning function of the TV remote features learning, this class will be able to freely control the various features of the TV set.
