The invention relates to the technical field of plant condition monitoring, and discloses a plant condition monitoring method, device, system, and apparatus, and a storage medium. The method comprisesthe steps of: obtaining the status of the factory change item, and setting a score value of the status of the factory change item to obtain the status score value of the factory change item, whereinthe factory change item at least comprises a change in output, a change in inventory and a change in a production-sales balance; and the status of the factory change item at least comprises four states of normal, attention, abnormality and early warning; The plant state score is calculated according to the plant change item state score, and the plant state is judged according to the plant state score. The invention monitors the status of each factory change item in the production process in real time, and digitally processes the status of each factory change item to monitor whether the statusof the factory is normal or not, so as to achieve the purpose of real-time monitoring the production situation, timely discovering the production error, and making the plant operation more efficient.
