The invention relates to a dispatching vehicle route optimizing method for an electric energy metering device. According to the method provided by the invention, the reality of a provincial metrology center is combined to convert the dispatching vehicle route optimization problem of the electric energy metering device into the combination optimization of a traveling bag (TSP) with a central library; with the goal of the shortest dispatching path and the economic optimality, an electric energy metering device dispatching vehicle route planning model based on a discrete particle swarm algorithm is constructed, and a self-escaping method is used to realize global optimization; the best single-line dispatching vehicle route is acquired; intelligent electric energy metering device dispatching is realized; the shortcomings of a traditional man-made dispatching route are effectively avoided; and the method effectively supports the power business expanding service business of a company.
