The present invention relates to a hall-call board positioning method and system. The hall-call board positioning method comprises the following steps: acquiring a Bluetooth signal corresponding to each hall-call board and received by a Bluetooth communication module installed at an interior-call board so as to obtain a plurality of Bluetooth signals of the hall-call boards, wherein the Bluetooth communication modules are installed at the hall-call boards; broadcasting the Bluetooth signals by the hall-call boards through the corresponding Bluetooth communication modules; sequencing the Bluetooth signals of the hall-call boards according to the intensities of the signals to obtain the first Bluetooth signal having the highest intensity; finding out the first hall-call board corresponding to the first Bluetooth signal from the hall-call boards; acquiring the floor on which an elevator car is positioned; and positioning the first hall-call board according to the floor, wherein physical floor position information is not required to be set for each hall-call board of an elevator system, so that the workload in a hall-call board positioning process is reduced, and further the positioning efficiency of the elevator car is increased.
