With the continuous acceleration of life rhythm and the continuous improvement of economic level, the demands of home users for a sense of security are gradually increasing. In many large and medium-sized cities, while people choose high-end apartments and villas, their awareness of home security continues to increase. In addition to the security projects designed and constructed by real estate companies and construction companies, and based on the existing "community security, security and air defense" mode, people's independent choices and purchases have gradually been integrated. As an indispensable part of the smart home, the home security system will also become a family expenditure that must be considered after choosing a house and buying a house, just like family house decoration.

The IoT smart home system, which came into being, not only can realize the control of smart home appliances, smart lighting, smart curtains, etc., which facilitates life and improves quality, but also can realize all-weather three-dimensional security monitoring, build a three-dimensional security system for residents, and guarantee The safety of family life and property.

Second, the working principle and structure distribution of the IoT smart home security system

A complete set of smart home security alarm system can ensure the safety of every user's life and property. The IoT smart home security system provides a basic home security system for smart home residents. It is divided into front-end detectors, smart home controllers, network signal transmission systems, and control center control systems.

In particular, the front-end IoT sensor of smart home can be divided into wireless door sensor, wireless window sensor, wireless gas detector, wireless smoke detector, wireless infrared probe, wireless emergency button, etc. If someone illegally invades, the corresponding detector will be triggered. The home alarm host will immediately send the alarm signal to the community management center or the phone designated by the user, so that the security personnel can quickly alert the police, and the alarm host of the community management center will record these. Information, ready for review.

In addition, the smart home security system has strong adaptability and compatibility, and has different functions such as indoor intelligent alarm, perimeter automatic alarm, video monitoring, induction card access control and internal communication. Various functions use the intelligent system network transmission part and The front-end home intelligent controller of the system can complete its own control based on setting its own controller and management software. At the same time, the system also provides users with a variety of control methods for electrical appliances in the home, no matter where the host is. , Can timely understand the use of electrical appliances in the home and control them. For example, when the host is on a business trip, he can open the air conditioner and electric curtains in the house to keep the indoor air fresh by telephone or Internet; or when the host is at home, the remote control can be used to switch the scene of the indoor lights.

3. Specific performance characteristics:

From a security point of view, the smart home security system can realize the level of security of home security alarm points, and use logical judgment to avoid false alarms of the system; the remote control or keyboard can be used to arm and disarm the system. Once an alarm occurs, the system automatically Confirm the alarm information, status and location, and can automatically force the line when an alarm occurs. The following categories introduce the functional features and applications of the IOT smart home security system in the home:

Major equipment:

1. Wireless router

2. Smart host (wifi single or 4-way host)

3. Mobile terminal, wall-mounted machine, control terminal

4. Smartphone or computer

5. Wireless infrared detector, door sensor, smoke sensor, gas, intelligent switch, socket, etc.

6. (The above settings can be increased or decreased according to the actual situation)

The main function

1. Alarm and linkage function. By installing door magnets and window magnets to prevent illegal intrusion, the host and community guards can get signals from the community management center through the alarm controller installed in the resident's room to quickly pick up the police. At the same time, the alarm linkage control can automatically turn on the indoor lighting and start the alarm when the system sends out an alarm message when an alarm occurs indoors.

2. Emergency help function, the alarm controller installed in the room has an emergency call function, and the community management center can respond and rescue the residents' emergency help signal.

3. Alarm management display function. When residents leave their homes, they are armed with anti-theft alarm status. In order to effectively prevent illegal intrusion, the management system of the community property center can receive alarm signals in real time, automatically display the alarm household number and alarm type, and automatically archive system information.

4. Set / disarm linkage control: When the host starts the safety protection system before going out, the system can also cut off the power supply of certain household appliances, for example: turn off all lights, cut off the electric appliances such as electric irons, electric kettles, televisions, etc. Socket power supply, etc .; when the owner returns home, it can be adjusted to normal, enter the home disarming mode, some lights are automatically turned on, the door magnet and window magnet are offline, and the indoor smoke detector and kitchen combustible gas detector are still in the alarm mode.

5. Preset alarm function. The intelligent security system can preset alarm phones, such as 110, 120, 119, etc., to carry out different alarms and realize networking with the community. In addition, an alarm can be sent to the resident's mobile phone or a designated phone by preset.

Of course, the home intelligent security system is an important part of the intelligent residential community. Through the real-time monitoring and layered defense of the community and key areas of the home through the community and the home security system, the residents of the community can live in the invisible anti-theft network. The advanced Humanized prevention has also provided a three-dimensional, all-round security guarantee for intelligent residential quarters.

4. Application Examples

Nanjing Wulian Sensing Technology Co., Ltd. () is a well-known enterprise engaged in the research of Internet of Things earlier in China. After years of dedicated research and development, it has successively launched products and projects such as Internet of Things sensors, Internet of Things modules, smart homes, etc. attention. In recent years, the company has joined forces with several well-known real estate development companies in China, complemented resources, and launched application examples such as "smart communities" and "smart homes", which have been welcomed by the majority of owners.

In the west of Hangzhou, more than 120 families in a high-end community installed the IoT smart home system, which not only improved the quality of life, but also protected life and property. At 2 pm on December 15 last year, Mr. Chen Guangming, who lives on the 5th floor of the community, was working. The mobile phone on the table suddenly vibrated and rang. He turned on the phone and looked at the picture. Prying the door, intending to break in illegally, and at the same time, the mobile phone message prompts: Someone broke in illegally, please pay attention.

Mr. Chen immediately contacted the community property and asked the other party to send a security guard to check the situation. Three minutes later, two security guards rushed to Mr. Chen ’s house and saw a man with a panicked look at the door. He was prying the door with iron tongs. He immediately took his uniform and twisted it to the police station.

Later, Mr. Chen learned the whole process of the matter and said excitedly: "After the IoT smart home, although people become lazy, the safety factor has been greatly improved." According to the property of the community, since the owner installed the IoT smart home system, the entire community has built a three-dimensional prevention and control system, and the number of burglary cases has been greatly reduced. Even if the case occurs, it is also an attempt to commit the crime, which really makes the owner ’s life and property safe Guarantee.
