3. Thoughts and Framework of System Implementation
Wireless communication transceiver module is the core part of smart home management system in the
basis of wireless control module, which has wireless and wired control function, wireless
communication and network communication function, sensor signal acquisition function. Among them,
this system uses wireless communication module to communicate with the external network server
and the local smart phone terminal in real time, and uploads the collected data in real time. It accepts
the control commands of the server or mobile terminal to control the local machine and the
extension-controlled equipment; 433MHz wireless communication with the extension is used to
transmit the commands of the server and the mobile terminal to the extension, and reads the sensor
information of the extension.
As shown in Figure 1 below, the intelligent home management system based on wireless control
module consists of four modules: ARM main control unit, information acquisition of extension room,
equipment control of extension room and information receiving and receiving module.

Intelligent Home Management System Architecture Based on Wireless Control Module: The data
collected by the main control board module of ARM is used to control the equipment in the extension
room. At the same time, the relative data and control information will be transmitted to the
communication transceiver module of the host in real time, and the real-time control of the mobile
phone will be realized. Among them, the module of the extension room does not have the network
interface, 315MHz and 433MHz wireless transmitting module than the host module. The
communication between the module of the extension room and the host module adopts the
master-slave mode, and the host actively accesses the extension.
4. Key Technologies of System Implementation
4.1. Infrared technology
Infrared technology studies the generation, transmission, transformation, measurement and application
of infrared radiation. Usually, it is divided into three parts: near, medium and far infrared. Near
infrared refers to the wavelength of 0.75-3.0 micron; mid-infrared refers to the wavelength of 3.0-20
micron, and far infrared refers to the wavelength of 20-1000 micron. In spectroscopy, the methods of
band division are not uniform. Some people use 0.75-3.0 micron, 3.0-40 micron and 40-1000 micron
as near infrared, mid-infrared and far-infrared bands. In addition, due to the absorption of infrared
radiation by the atmosphere, only three important "window" areas are left, i.e. 1-3 micron, 3-5 micron
and 8-13 micron, which allow infrared radiation to pass through. Therefore, in military applications,
these three bands are called near infrared, mid-infrared and far-infrared respectively.
The infrared radiation characteristic of infrared technology is applied in intelligent home
management system based on wireless control module. The equipment control module is divided into
two categories: infrared emission module and relay output module. Among them, the infrared
transmitter module uses infrared technology to capture and transmit signals. Then data is submitted to
the device control module in real time.
4.2. Sensor technology
Sensor is a kind of detection device, which can sense the measured information and transform this
information into electrical signals or other required forms of information output according to certain
rules to meet the requirements of information transmission, processing, storage, display, recording and
control.

module is also a key module, which includes temperature sensor, humidity sensor, illumination sensor,
air sensor and infrared sensor. A variety of sensors can transmit real-time information such as
temperature, humidity, illumination, air and infrared ray to ARM main control board for processing.
There are many types of sensor modules, thus the characteristics and practicability of various sensors
should be taken into account in the selection. The selected sensors in the system are: dust sensor
(SYHITECH dust sensor DSM501A in Korea), human infrared sensor (HC-SR501 human infrared
induction module (pyroelectric sensor), illumination sensor (PO188), noise sensor (environmental
noise detection module), temperature sensor (NTC thermal resistance 10K), etc.
4.3. Wireless control technology
The smart home management system based on wireless control module uses the mobile phone to
control the wireless communication module to achieve the goal of controlling the information terminal.
The smart home management system is also composed of three main functional modules: ARM main
control board, sensor data acquisition module and equipment control module. The smart home
management system is then interconnected by wireless local area network to achieve many control
functions of transmitting data and controlling information. The structure diagram of the wireless
transmission control unit of the system is shown in Figure 2.

The host address settings include host IP, host MAC, host sub-net mask, gateway, remote server IP
and remote server TCP port. The name of the host is provided by the ID address of the host, and the
control of mobile phone access is accomplished by the remote server in the external network and by
wireless communication in the internal network.
5. System Solution
The specific solution of the smart home management system based on wireless control module is to
take the control of wireless control module as the core, and interconnect the communication between
host and mobile terminal, host and server, host and slave, host and equipment to realize the functions
of information collection, data processing and command transmission.
5.1. Host and mobile terminal
Host and mobile terminal initiate TCP connection to host directly through WLAN under a wireless
router and in the same LAN. After successful connection, mobile terminal communicates with host
through WLAN. When there is no external server, the mobile phone can automatically find the host in
the LAN.

5.2. Host and server
The host forwardly initiates TCP connection to the server. After successful connection, the server
sends registration confirmation to the host and then the host sends back its own setup data. By
comparing the corresponding setup data with the information in the database, the server can send out
control information. Specific connectivity conditions are as follows:
 Host sends Ping package to server regularly to let server know the IP address of host. After
the server knows the IP address of host, it accesses the host through browser.
 In addition to informing the IP address to the server regularly, the host is slave to the server
and is always in the mode of reply, as opposed to the way of communication between the server and
the mobile terminal.
 The control commands issued by the server include room number, device number, command
coding information and others.
5.3. Master and slaves
The master and slaves use 433MHz wireless communication. The communication mode is the
master-slave mode that the host polls the slave to obtain sensor data. When the mobile terminal or
server sends the slave device control commands, the host transmits the command to the slave and
controls the equipment in the slave room to run.
5.4. Host and equipment
After receiving commands from servers and mobile terminals, the host controls the operation of
related devices through 315MHZ transmitter module, 433MHZ transmitter module and infrared
transmitter unit.
6. Conclusion
In this paper, a smart home management system based on wireless control module is proposed to solve
the difficulty of control of household appliances. With the application of infrared technology and
sensor technology, the real-time control of household appliances is realized. In addition, users can also
use the data acquisition information provided by the system to determine the use of household
appliances and use safety, reduce waste of electricity, effectively remove the potential safety hazards
caused by electricity, thereby enhancing social energy conservation and emission reduction, stability
and harmony. What’s more, each module of the system can achieve more control functions through
expansion, which plays a certain role in promoting the follow-up development of smart home
technology.
