The invention discloses a slab manufacture quality monitoring pre-warning system package device, and relates to the technical field of quality monitoring pre-warning. The device comprises a database unit, as well as a data collection unit and a pre-warning report unit which are connected with the database unit, wherein the data collection unit is used for collecting each quality monitoring parameter in a slab producing process, and transmitting the quality monitoring parameter to the database unit; and the database unit is used for determining whether the quality monitoring parameter exceeds the threshold of a standard design parameter, and transmitting the quality monitoring parameter to the pre-warning report unit if the quality monitoring parameter exceeds the threshold of the standard design parameter. By utilizing the device, real-time dynamic monitoring of the slab manufacture process and timely quality pre-warning are realized for the first time in the slab precise manufacture industry, critical data can be reviewed, regenerated and re-derived by adopting an Internet of things technology, and powerful assurance is provided to slab construction and operation maintenance, thus the device has significant meanings in assuring high-speed rail quality, constructing digital railways and improving the railway operation intelligent level.
