The invention provides an array localization device which comprises a host and multiple operation modules. The host at least has a processor and a first communication unit. The operation module at least has a neighbor detection unit and a second communication unit. The neighbor detection unit includes multiple sensors distributed at the edge of the operation module. Each sensor contains a single generator and a signal inductor which are arranged in parallel along the edge of the operation module. During clockwise/anticlockwise observation of the signal generator and the signal inductor in each sensor, the signal generator is always positioned in front of/behind the signal inductor. The invention also provides an array localization method based on data analysis. The method is used for array localization of the multiple operation modules in the above array localization device. The array localization method based on data analysis with the combination of the above array localization device is used in the field of interactive intelligent toys, and has a good application effect.
