An electric tool system, including an electric tool and a charger. The electric tool system includes: a voice obtaining component, obtaining voice information from a user; and a control module, obtaining instruction information generated based on the voice information, and controlling the electric tool system based on the instruction information to perform a corresponding action, where the electric tool system includes: a voice processing component, at least configured to generate information that corresponds to the voice information and satisfies a transmission format of a communications component; and the communications component, sending the information processed by the voice processing component to a server, receiving response information from the server, and providing the response information to the control module, where the instruction information includes the response information. The beneficial effects of the present invention are as follows: A user may directly send a request by using voice information, thereby conveniently obtaining various required information or implementing various controls, so that an electric tool system becomes a “personal worksite assistant” of the user, thereby extending the functions of the electric tool system.

An Internet of Things sanitization system and method of operation through a blockchain network provides one or more independently operating sanitizing assemblies comprise a reservoir containing sanitizing medium and a sanitizing mechanism work to sanitize/clean a surface. The sanitizing assemblies connect through a blockchain network, so as to generate, collect, process, and communicate data pertinent to the cleaning. The data is transmitted across a peer-to-peer network, such as a blockchain network for the purposes of: identifying a user; determining which of the sanitizing assemblies and components thereof are operable, and determining usage metrics of the sanitization assemblies. Data is collected directly from the sanitizing assemblies through various user input interfaces. An Internet of Things motherboard operational in the sanitizing assemblies to enable communication between sanitizing assemblies, network nodes, and a centralized server. A network controller and a network interface enhance operation and communications for the sanitizing assemblies.
