The invention discloses a network communication system used for power load control and a routing algorithm of the network communication system. The system comprises a master station computer, a front-end processor, base stations and a plurality of intelligent terminals, wherein the intelligent terminals are connected with the base stations in a wireless ad hoc network mode; the base stations and the master station computer are connected through wire links; the front-end processor serves as interface equipment of the master station computer and classifies, collects and distributes data between the master station computer and the base stations; forty discrete frequency points are divided into be seven frequency point collections through the system, every two adjacent base stations use different frequency point collections, and all the base stations carry out pilot frequency cellular networking according to the cellular networking structure of seven cells. According to the network communication system used for the power load control and the routing algorithm of the network communication system, power load information is obtained through the wireless intelligent terminals and is connected into the base stations in a single-hopping or multi-hopping mode, network access and routing maintenance can be achieved automatically, unified management on the intelligent terminals is achieved, the coverage rate of signals and the system capacity are enlarged, the real-time performance of communications is enhanced, and safety of the data is ensured.
