On August 22, the 2022 China International Intelligent Industry Expo opened in Chongqing Yuelai International Conference Center, and Tongliang district made an appearance with intelligent applications. (Luke intelligent security experience center.) "Fingerprint unlocking is not uncommon now, but it is rare to unlock with finger vein." The on-site staff pointed to the smart door in front of them and said, "in this way, there will be no sweating or peeling of hands, which will lead to difficulties in unlocking fingerprints." In the Luke intelligent security experience hall, the staff put their fingers into the door handle, and the door opened, and the lights in the experience hall also lit up. "Our door is equivalent to a 'brain', which can be connected to all kinds of electrical appliances in the house. When people enter the house, they connect the power supply, and when they leave, they close it automatically." The staff said. It is reported that the smart door can realize the integration of the whole house, intervene in the Mijia ecology, connect with the whole house smart home, and customize the smart link mode. Its data is encrypted in the whole process of storage, transmission and reading, which can ensure the safety of users. (booth of new energy storage industry development demonstration zone.) The exhibition hall of Tongliang district also displayed the development achievements of the new energy storage industry through multiple application scenarios. As one of the representatives of the new energy storage industry, Haichen energy storage precision positioning electric energy storage and household energy storage market promotes the rapid development of the industry with professional energy storage batteries. In the application scenario of public institutions, the light storage project of the power supply service center of the high tech Zone uses the roof photovoltaic of the power supply service center of the high tech Zone, configures 10kwh energy storage equipment on the load side, and uses comprehensive energy using modes such as photovoltaic "self use surplus electricity on the grid" and energy storage equipment "Valley charging and peak discharging", to achieve the purpose of reducing emission and power consumption cost, and provides a demonstration scenario for light storage application for public institutions. In the "micro grid" application scenario of the power science museum, "photovoltaic + energy storage" has changed the household energy consumption mode. The Power Science Museum of Jinlong power supply business hall of State Grid Tongliang power supply company integrates the "photovoltaic + energy storage" scenario, forming a new type of "micro grid" with the whole process of "generation, storage, distribution and utilization". It is equipped with 10kW photovoltaic and 20kwh supporting energy storage, showing the new energy and energy storage application to the public, and providing a demonstration scenario of light storage application for residents' living electricity.
