Automatic bad weather road condition early warning system

The invention discloses an automatic bad weather road condition early warning system which includes: a sensing module which can detect atmospheric visibility, road freezing or high temperature states, deformation level at bridge connection places and bridge surface temperature; an on-site processing center which can, on the basis of the atmospheric visibility, road freezing or high temperature states, deformation level at bridge connection places and bridge surface temperature, check up a corresponding on-site abnormal data level from one on-site abnormal data level query table, and based on the on-site abnormal data level that is checked, check up a corresponding on-site early warning plan from one on-site early warning plan query table; an on-site early warning module which implements a corresponding early warning action based on the on-site early warning plan; a cloud processing center which, based on the checked on-site abnormal data level, checks up a corresponding diagnosis result from one expert database, and based on the checked diagnosis result, acquires a corresponding remote early warning plan; and a remote early warning module which based on the remote early warning plan, implements a corresponding early warning action.
