The invention relates to a physicochemical detection control and information management system. A lab is taken as a center, and the business flow, environment, personnel, project management and client management of the lab are integrated for monitoring. The system consists of a task management subsystem, an experiment management subsystem, a report management subsystem, a checking subsystem, a system management subsystem, a resource management subsystem, and a statistics and analysis subsystem, wherein each subsystem is contained in a corresponding packaged. A real-time message transmission mode and a periodic scanning double-channel mechanism based on the Ethernet are employed for the data transmission among the subsystems. The layered logic configuration of each subsystem sequentially comprises a data collection layer, a data layer, a data processing layer, a business layer and a presentation layer from the bottom layer. The system standardizes a physicochemical detection flow, controls the randomness of a detection link, is high in system response speed, is low in fault rate, is simple and standard in operation, is high in traceability and safety, achieves vivid statistics and analysis of a historical detection task, improves the work efficiency and quality truly and effectively, and irons out a gap of informationized management of physicochemical detection.
