Recently, the author learned from the relocation of NB-IoT narrow-band Internet of Things commercial conference was informed that the province's first central city narrow-band Internet of Things applications in the city of commercial use. This means that NB-IoT technology will formally enter the stage of application promotion in our city, and will bring new experiences of “wisdom living†to the majority of Suqian citizens in the wider livelihood area. What is NB-IoT technology? According to mobile workers, NB-IoT (NarrowBandInternetofThings) is a narrow-band, cellular-based Internet of Things. It is mainly used in small-data-rate, low-speed Internet of Things scenarios and is a breakthrough technology that enables the Internet of Everything. NB-IoT has better security, deeper coverage, longer battery cycles, and features such as wide coverage, multiple connections, low speed, low cost, low power consumption, and excellent architecture. The technology has broad application prospects in areas such as smart transportation, smart agriculture, smart logistics, energy conservation and environmental protection, and security monitoring. In the IoT product experience area, the relocation staff also introduced several project applications based on the NB-IoT technology, depicting the future “All Things Connected†picture. Smart agriculture. Based on the Internet of Things technology, real-time collection of light, temperature, humidity and other parameters of the agricultural production site, digital transformation of the collected parameters and information, through the NB-IoT network transmission to the intelligent platform for summary integration, according to the growth of agricultural products The indicators require that the designated agricultural equipment be automatically turned on or off in a timely and accurate manner (such as remote control of water-saving irrigation, energy-saving and oxygen-increasing, rolling shutter switches, etc.) to realize an intelligent and automated agricultural production process. Smart street light. The “Smart Streetlight†project is based on NB-IoT technology, changing the traditional group control mode to single-control mode, with the advantages of adjustable light brightness, shortened single lamp control delay, reduced operating costs, etc., with NB-IoT technology as The basic single-control intelligent street lamp solution avoids the disadvantages of frequent construction of single-control mode, serious power line transmission interference, limited transmission distance, and low data reporting accuracy, and improves the work level of street lamp management informatization. For example, you can automatically adjust the brightness of the light in combination with latitude, longitude, and daylight hours, and only about this one can save about 10%. In addition, it can also meet the management needs of remote management, fault location, and save about 50% of maintenance costs. Smart meter reading. Through the built-in Internet of Things card, real-time transmission of residential water meter data to the water supply information service platform enables remote automatic meter reading, which is convenient and quick. It can also save the cost of manual meter reading for utility companies while improving meter reading efficiency and accuracy. It will facilitate the collection and collection of water, electricity, gas, and heat meter sets, and “combination of four tablesâ€. In the future, home gas meters, water meters, etc. will no longer need to be checked. Using NB-IoT terminals, smart meter reading functions can be realized. Smart parking. The NB-IoT technology can solve parking lot monitoring problems: The car owner's parking space status information data is sent directly to the nearby base station and then transmitted to the intelligent parking server located in the engine room. The user can realize functions such as parking space inquiry, reservation, navigation, and parking lot management on the mobile phone, which solves the problem of the driver's difficulty in finding a parking space, and alleviates the problems such as occupied private parking spaces and traffic jams to a certain extent. With the maturation and application of NB-IoT technology, various smart applications will be deployed in the ubiquitous NB-IoT network, such as intelligent transportation, smart medical care, smart home, and industrial Internet of Things. It is learnt that in the next stage, the company will further increase the development and application of the NB-IoT narrow-band Internet of Things network, and is committed to promoting its application in areas such as smart homes, car networking, smart transportation, and smart medical services. The application will effectively promote the construction and development of a smart city connected to the Internet of Things.
