The invention discloses a work order processing method and a work order processing device. The method comprises the following steps: detecting whether there is a to-be-done work order finished; when detecting that there is a to-be-done work order finished, updating a to-be-done work order pool, wherein the to-be-done work order pool is used for storing to-be-done work orders; acquiring all to-be-done work orders from the to-be-done work order pool, wherein each to-be-done work order corresponds to one to-be-done event; determining the time limit information corresponding to each to-be-done event, wherein the time limit information is used for describing the degree of priority of the corresponding to-be-done event; and sorting all the to-be-done work orders according to the determined time limit information to get a sorting result. The technical problem in the related technology that the work order processing procedure and the work efficiency are affected as the working staff does not handle to-be-done tasks in time is solved.
