Abstract: The use of intelligent robots and mobile operation terminals accelerates the speed of the realization of unattended substation. These wireless terminals need to be managed and monitored in a unified way. In particular, the illegal access terminal must be detected and screened. For the reason that the possibility of forging MAC address information of illegal terminal cannot be excluded. Location information is used as the terminal identity, so it can be detected and illegal terminals can be discriminated. At present, the distance calculation localization method and the database matching localization method have been proposed. In this paper, combining with the triangle distance calculation method and database matching method, a new entropy weight fusion localization algorithm is provided. The algorithm determines the entropy weight according to the concept of information entropy in the information theory. It improves the intelligent robot positioning accuracy and the ability to detect illegal terminal.
