Research on Smart Lab Based on Internet plus

       At present, most laboratories still face many problems such as fragmented information management, manual equipment management, non intelligent security management, non low-carbon environmental management, and non shared resource management. Through the integration of various intelligent subsystems and the use of Internet of Things technology, "Internet plus" technology, database and other technologies, people can grasp the situation of the laboratory no matter where they are, and carry out interactive purpose operation control. Thus, it can provide efficient, convenient, and scientific management methods and techniques for laboratory management departments.

Three layer architecture of smart laboratory

       1 Smart laboratory perception layer
       Through sensors, cameras, access locks and other sensing nodes, the laboratory is perceived in real time through the "Internet plus" technology, and real-time data collection is carried out for information such as the activities of personnel in the laboratory, the status of articles in the laboratory, and the status of the laboratory environment. The collection frequency should be scientifically set according to the needs of laboratory management
       2 Smart laboratory transmission layer
       In the smart lab, wired, wireless (including Wifi, Bluetooth, Zigbee, IPv6) and other "Internet plus" technologies are used to realize real-time interconnection of sensing nodes, and transmit audio, video, laboratory experiment course management and other information of the smart lab anytime and anywhere. The transmission layer of the smart laboratory is the network foundation for achieving information transmission
       3 Smart laboratory application layer
       The application layer of the smart laboratory includes various intelligent applications, directly targeting users at all levels. For example, management personnel can dynamically monitor the temperature and humidity of the laboratory, whether there are people, and the use of laboratory items in real time. Energy saving control can also be implemented in the laboratory by utilizing Bluetooth and photosensitive sensors to regulate the lighting intensity. And experimental personnel can download experimental materials, book laboratory equipment online, book open experiments online, and sign in. And the intelligent management function of the application layer also requires data storage, data mining, information security and other related service support

Intelligent subsystems of the smart laboratory

       1.Smart laboratory access control management subsystem. The smart laboratory access control management system seamlessly connects with the digital and laboratory management systems, exchanging information and recording valid data
       2.Smart laboratory item management subsystem. The smart laboratory item management subsystem adopts RFID technology and Zigbee technology. In practical applications, readers write data in a specific format into RFID tags and then attach the tags to the surface of experimental items
       3.Smart laboratory monitoring subsystem. The smart laboratory monitoring subsystem consists of five main components: camera, transmission, control, display, and recording registration, which provide remote video monitoring functions. Including host, front-end camera array unit, server, and central management storage unit for storing image recording, video playback, image monitoring, configuration data, and automatic downloading of video files, as well as WiFi communication module
       4.Smart laboratory comprehensive management subsystem. The comprehensive management subsystem of the smart laboratory includes unified arrangement and management of laboratory comprehensive management (laboratory organization, personnel, environment, safety, evaluation, data), experimental teaching management (experiment reservation, experiment management, experiment monitoring, score attendance), asset and equipment management (equipment and instruments, materials and consumables, large equipment, equipment electrical control), and daily office management (announcement and notification, online resources, communication)
       5.Smart laboratory intelligent network shutdown upper computer server. In the smart laboratory, wireless networks such as Bluetooth, Zigbee, and WiFi are involved, and an intelligent gateway is needed to provide data conversion services between multiple networks. In addition to integrating wireless communication functions, this intelligent gateway also has three important functions: the first function is the collection and data analysis of various sensor signals; The second function is to store applications and data at startup; The third function is to send parsed data to the upper computer server。
       The smart lab system based on "Internet plus" technology is of great significance in open service, scientific management, resource sharing, etc. This technology can be further extended to more application fields such as smart cities, smart homes, smart grids, smart logistics, smart commerce, smart industry, etc。
