The invention relates to a distribution first-aid repair team cooperation information support system based on a wearable device. The system comprises a master station system and a mobile end system, wherein the mobile end system comprises a hardware device layer, a communication middleware layer, a personal work state analysis engine and an application layer. The hardware device layer is composed of an intelligent hand-held device and the wearable device. The personal work state analysis engine performs perception determining on the state of work personnel on the basis of a sensor on an intelligent device and communication content analysis. The application layer comprises such application programs as a team work mode control program and the like. According to the invention, information processing work of first-aid-repair command is enabled to cover the whole team, through introducing the wearable device, based on a distribution first-aid repair team work organization mode and the work state of team members, an information interaction mode suitable for a personal current work state and an information interaction mode between first-aid-repair team members and between a first-aid-repair team and the master station system are dynamically controlled, and the bidirectional information interaction difficulty between a present first-aid-repair command center and onsite first-aid-repair personnel is effectively solved.
