Today, the concept of “Internet of Things” is no longer unfamiliar. However, what kind of surprises can the applications based on the Internet of Things bring to people’s lives? At this year’s Optical Expo, through the demonstration by the staff, non-professional audiences can intuitively feel that “smart city” is no longer a concept, and the “smart” life in the digital age is not far from Jiangcheng citizens.
“Smart community” to be piloted
The reporter saw in the high-tech exhibition area in Wuhan that water heaters, air conditioners, and various power switches and circuits were hung on one wall. According to the staff, only a “smart” remote control is needed to perform any operation within a range of 20 meters to 30 meters: for example, remote control the water heater switch in the bathroom in the living room, and turn off the lights in the living room in the bedroom. All of these operations are realized by infrared radio frequency remote control equipment. Just install an infrared receiving device on each electrical appliance to receive the commands sent by the radio frequency remote control.
When citizens are at home, they can use the centralized remote control to “catch all” household appliances; when they go out, they can send text messages with their mobile phones, and receive and transmit instructions through the wireless control gateway, so that the rice cooker at home starts cooking and the water heater starts. Work, the lights in the living room are turned on, the background music is playing… In addition, by connecting to the Internet, you can monitor the real-time situation at home through your mobile phone.
It is understood that three communities in Wuhan are currently working on the design of a “digital home”, and at least one of them will become a “smart community” within the year.
Meat dishes can be traced
For a cup of Lipton Malt Milk Tea, scan the barcode on the outer packaging, and with a “beep” sound, the electronic display will display information such as the raw material planting place, manufacturer, warehouse name, shipping unit and shelf time.
At present, the most convenient food source inquiry system – “Meat and Vegetable Circulation Traceability System”. According to the staff, the latest traceability system is based on the Internet of Things and adopts the most advanced data exchange platform in the industry. It is not only easier to operate, but also can automatically identify one-dimensional codes and two-dimensional codes, and store more information. In addition to the “vegetable basket” The origin, processing enterprises, wholesalers, and even storage locations, shelf times, etc.
Taking vegetables as an example, once it is found that the pesticide exceeds the standard, the shortage of jins and liang, and the price increase in disguised form, consumers can quickly trace whether it is local or foreign, where it is produced and wholesale, and which vegetable market and which stall sells it. Consumer rights.
According to reports, Digital China brought a series of “Smart City” solutions to the Expo for the first time. Since winning the bid for the “Smart Wuhan” top-level design project in March this year, it will pass a series of projects such as the “Citizen’s Home” government affairs network. Accelerate the construction of “smart city” in Jiangcheng.
