1. Implementation background
When the owner is out, use the mobile phone to switch to the “away” state, and issue orders to turn on and arm all the security equipment in the home; when the owner is at home, the smart gateway automatically turns off the infrared sensor detector, door sensor, window sensor alarm and anti-theft probe, and at the same time Turn on the smoke, fire, gas and other probes; you can also set various types of probes to open and close to achieve arming according to needs. Once someone triggers these probes, the system can send an alarm signal to the owner or the community property while automatically alarming.
Such a safe and reliable home security monitoring is not only realized in a dream, but now it can be easily done with a mobile phone. This is the magical convenience and sense of security brought by the smart home security system.
With the continuous acceleration of the pace of life and the continuous improvement of the economic level, home users’ needs for a sense of security are gradually increasing. In many large and medium-sized cities, people’s awareness of home security continues to increase while choosing high-end apartments and villas. In addition to the security projects designed and constructed by real estate developers and construction engineers and the existing “community security, security and civil defense” model, it has gradually integrated people’s independent choice and purchase. As an indispensable part of the smart home, the home security system will also become a household expense that must be considered after choosing a house and buying a house, just like the decoration of a family house.
The IoT smart home system that emerged at the historic moment can not only realize the control of smart home appliances, smart lighting, smart curtains, etc., but also facilitate life and improve quality. It can also realize all-weather three-dimensional security monitoring, and build a three-dimensional security system for residents to ensure To ensure the safety of family life and property.
2. Working principle and structure distribution of 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 basic home security systems for smart home residents, including front-end detectors, smart home controllers, network signal transmission systems, and control center control systems.
In particular, the front-end IoT sensors of smart homes can be divided into wireless door sensors, wireless window sensors, wireless gas detectors, wireless smoke detectors, wireless infrared probes, wireless emergency buttons, etc. If someone illegally invades, the corresponding detector will be triggered. The home alarm panel will immediately transmit the alarm signal to the community management center or the phone designated by the user, so that the security personnel can deal with the alarm quickly. At the same time, the alarm host of the community management center will record these Information is available for inspection.
In addition, the smart home security system has strong adaptability and compatibility. It has different functions such as indoor smart alarm, perimeter automatic alarm, video monitoring, proximity card access control and internal communication. Various functions use the intelligent system network transmission part and The front-end home smart controller of the system can complete their own control based on setting their own controller and management software. At the same time, the system also provides users with multiple control methods for the electrical equipment at home, no matter where the owner lives. , Are able to understand the use of electrical appliances in the home and control them in time. For example, the host can open the air-conditioning and electric curtains in the home through the phone or the Internet to keep the indoor air fresh; or when the host meets guests at home, he can use the remote control to switch the indoor lighting scene.
3. Specific performance characteristics
From the perspective of security, the smart home security system can realize the level of home security alarm points, and use logical judgment to avoid false alarms; 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 to be busy when the alarm is issued. The following categories introduce the features of the IoT smart home security system in the home as long as the equipment and application functions:
Major equipment:
1. Wireless gateway
2. Smart host (wifi single-channel or 4-channel host)
3. Smartphone or computer
4. Wireless infrared detectors, door sensors, smoke detectors, gas, smart switches, sockets, etc.
The main function
1. Alarm and linkage function. By installing door magnets and window magnets to prevent illegal intrusion, the owner and community guards can obtain signals from the community management center through the alarm controller installed in the residence room to quickly receive the alarm. At the same time, the alarm linkage control can automatically turn on the indoor lighting and activate the alarm when an alarm occurs in the room.
2. Emergency help function, the indoor alarm controller has an emergency call function, and the community management center can respond to and help residents’ emergency help signals.
3. Alarm management and display function. When a resident leaves home, the defense enters the mode of leaving home, that is, the anti-theft alarm state. 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 owner activates the security system before going out, the system can cut off the power of some household appliances, for example: turn off all lights, cut off electric irons, electric kettles, televisions and other household appliances Socket power supply, etc.; when the owner goes home, it can be adjusted to normal, enter the home disarming mode, some lights will automatically turn on, door and window magnets will be offline, while indoor smoke detectors and combustible gas detectors in the kitchen are still in alarm mode.
5. Preset alarm function. The intelligent security system can preset alarm telephones, such as 110, 120, 119, etc. for different alarms, and realize networking with the community. In addition, alarms can be sent to the residents’ mobile phones or designated phones by preset.
Of course, the home intelligent security system is an important part of the intelligent residential community. The real-time monitoring and layered defense of the community and the key areas of the home through the community and home security system can allow the residents of the community to live in the invisible anti-theft network. Humanized precautions also provide a three-dimensional and all-round security guarantee for smart residential communities.
Four, application examples
Nanjing Wulian Sensing Technology Co., Ltd. (www.wulian.cc) is a well-known enterprise engaged in IoT research earlier in China. After years of painstaking research and development, it has successively launched IoT sensors, IoT modules, smart homes and other products and projects. The attention of the majority of colleagues and users. In recent years, the company has joined forces with several well-known domestic real estate development companies, complemented resources, and launched application examples such as “smart community” and “smart home”, which have been welcomed by the majority of owners.
In the west of Hangzhou, more than 120 households in a high-end community have installed the IoT smart home system, which not only improves the quality of life, but also protects 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 ringed. He turned on the mobile phone and looked at the picture. A middle-aged man in his 30s. The door is being pried, with the intention of breaking in illegally, and the mobile phone text 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 panicked man at the door, holding iron tongs, prying the door, immediately uniformed him, and twisted him to the police station.
Later, Mr. Chen learned the whole process of the matter and said excitedly: “With the IoT smart home, although people become lazy, the safety factor is greatly improved.” According to the introduction of the community property, 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. Assure.
