Abstract
The invention provides a distance measuring method, a distance measuring device and electronic equipment. The method is applied to an access controller (AC), and comprises the following steps of: acquiring a basic service set identifier (BSSID) of a neighbor access point (AP) which is reported by an access point (AP) jurisdicted by the AC and has a fine time measurement (FTM) capability; a directed topological graph is constructed based on the obtained BSSID, the vertex of the directed topological graph is an AP, and an arc is used for representing that an arc head AP reports an arc tail AP as a neighbor AP; at least one arc set is determined based on the directed topological graph, the at least one arc set comprises an arc between any two adjacent vertexes in the directed topological graph, there are no repeated arcs and two opposite arcs of an arc head AP and an arc tail AP, and the arcs in each arc set accord with a concurrent ranging condition; and at least one round of concurrent distance measurement is controlled to measure the distance between the arc head AP and the arc tail AP of each arc in the at least one arc set, and each round of distance measurement corresponds to one arc set. Therefore, the ranging efficiency is improved, and resource waste caused by repeated ranging is also avoided.
