It is predicted that by 2020, the global IoT connection will reach 8.6 billion, 45% of terminals will use low-power wide area network (LPWAN) for wireless communication, of which LoRa accounts for 40%, LoRa has become the fact of the Internet of Things standard. LoRa's name is Long Range Radio, which has wide coverage, low power consumption, low cost and multiple applications. It is farther away from 2G wireless communication. The distance in open environment can reach 15Km. LoRa terminal power consumption Very low, a battery can be used for 3-5 years. Under the same conditions, the number of gateways required is small, no wiring is required, construction cost is low, and a variety of application access is also supported. It has been widely used all over the world. Urban, industrial and agricultural sectors.
As of the beginning of 2018, 95% of the sub-provincial cities and 83% of the prefecture-level cities in the country, more than 500 cities are planning or building smart cities, of which smart communities are one of the typical forms of expression. Shanghai Jing'an District, Pudong New Area and Putuo District have launched large-scale smart city construction in 2018, covering residential areas and industrial areas of the city. Beijing Haidian District claims to build 40 smart communities in 2019, and the Wuhan Municipal Government issued red-headed documents requiring 2019. Before August of this year, 500 smart and safe communities were built in the city, and the smart community has formed a prairie in the country.
A smart community with a rapidly growing number of countries across the country requires the use of next-generation information technologies such as the Internet of Things, cloud computing, and the Internet to integrate intelligent, safe, healthy, and efficient applications, based on the construction of communication networks, and to standardize and intelligently Consolidate the needs of property and owners, reduce construction and operation and maintenance costs, and improve community service levels. The needs of the owners need to be solved, and the property management needs to be profitable. Then the innovative application of the Internet of Things based on LoRa technology can meet the needs of the smart community and provide a safe, comfortable and convenient intelligent living environment for the community residents.
Every system in the smart community is wirelessly connected. How smart is the smart community of “Internet of Everything”?
Xiaobian takes you from the perspective of God and explores the “wisdom” of the smart community:
"Welcome to go home," a voice prompt came from a distance, and looked at it. It turned out that the owner came home. The parking system of the community has a complete set of functions, vehicle identification, positioning, vehicle owner information verification, parking space monitoring and so on. The radar sensor installed at the entrance of the community vehicle is used for vehicle arrival triggering, convenient installation, no wiring, and high triggering precision. The geomagnetic and ground locks of the fire exits and parking spaces in the community can continuously transmit the channel and parking space information to the network platform, and the background can monitor the traffic conditions and the vacant parking spaces in real time.
If you walk home, the community also has a very secure access control system, wireless access control, door locks, no wiring, support a variety of door opening methods. Residents can enter and leave the community through face recognition. The fingerprint unlocks the door to open the door. It can also send the access control and smart door lock temporary password through the mobile phone remote intercom to open the door for the visitor. At the same time, the door magnetic alarm system can upload the door and window switch information of the home in real time through wireless transmission to ensure the indoor environment safety.
The door magnetic alarm system is the first line of defense to ensure indoor safety. When entering the room, various security and fire alarm devices are also the most important. Wireless flooding alarm, wireless smoke alarm, wireless combustible gas detector, the installation of each line of defense is simple but the function is not simple. When the alarm detects abnormal information, it also uses local sound and light alarm, voice, SMS, WeChat, App push alarm information to remind users.
The outdoor intelligent fire water monitoring system adds another safety insurance to the residents. The equipment itself can remotely transmit the collected fire water tank liquid level and fire hydrant water pressure to the cloud platform through the LoRa wireless network, and the cloud platform saves and processes the uploaded data. When there is alarm information or fault information, notify the relevant management personnel through the monitoring center platform, WeChat, SMS, and APP to find and process them in time. It is true that the hidden dangers of fire protection can be checked, managed, and controlled.
The new community management model not only establishes a solid security protection system for the community, but also brings more convenience to residents' living.
The smart community has a high safety factor, the community environment is first-class, and the happiness of residents' lives is bursting. Take a closer look, the environmental monitoring system is a big hero. The temperature and humidity, PM2.5, water quality and even the data of the trash can can be collected and transmitted to the managers in real time through the Internet of Things technology to realize the environmental supervision of the community in all directions and without blind spots. Ensure the stable ecological environment of the community.
Unconsciously, it was dark, and the people in the community came to the car, and the street lights automatically lit up. The intelligent street lamp has the functions of automatically adjusting brightness according to people and traffic flow, remote lighting control, active fault alarm, remote meter reading, etc., which can greatly save power resources, improve public lighting management level, and save maintenance costs.
The smart community brings convenience and comfort to the owners, and the property can enjoy more comfort. Whether day or night, wind or sun, the smart meter reading system has functions such as metering, calculation, storage, diagnosis, wireless remote transmission, etc. The meter reading staff can copy the water meter of the whole community only by operating the background software in the office. Electric meters, gas meter data and remote control valves have the advantages of cost saving, simple operation and convenient maintenance.
What is Peggy? A variety of intelligent scenes, smart communities are all available to you! At the end of the day, the smart community is still the original formula, familiar taste, serene and quiet.
Do you know? A variety of intelligent equipment collections rather than the “everything connection” of big data sharing, the smart community does not have true “wisdom”. For example, the access control system and parking system of many communities are two information islands, and various devices cannot be used. Unified management. Therefore, a ubiquitous network that covers the indoor and outdoor unified wireless technology standards of the entire community is an urgent need of the current smart community. LoRa technology has the characteristics of low power consumption, wide coverage, high density, long distance, anti-interference, high sensitivity and low cost. It provides signal coverage for various IoT application scenarios and provides “Internet of Everything” in the community. may.
