The invention provides a resource scheduling method and a resource scheduling system for uplink services in a power wireless private network. The method comprises the following steps: receiving uplink wireless communication requests of services in a power wireless private network; dividing the services into different priority service libraries; acquiring the optimal services in the different priority service libraries and the uplink schedulable channel resources of the optimal services; and allocating the uplink schedulable channel resources to the services. The system comprises a request receiving module, a service prioritization module, a channel resource acquisition module, and a resource sending module. Quick and accurate data transmission of services in a smart grid is realized, low cost and high reliability are achieved, and the efficiency, intelligence and timeliness of data transmission in a smart grid based on a power wireless private network are improved.
