Therefore, the accuracy of signal acquisition is improved by adopting a mode of acquiring the average value for multiple times.
Furthermore, because the distribution density of the wireless internet of things devices can be different in different application environments, in some scenes with high density, some filtering needs to be performed on surrounding devices, so that each wireless internet of things device only collects wireless signals with a certain intensity value within a range, please refer to fig. 2, assume that a is a device for collecting signals, a collects wireless signals with signal intensity of-25 dbm-50 dbm, within the wireless signal strength range, the device B-device I exists, then the device a only collects the wireless signals of the device B-device I, and wireless signals of the devices 1-15 outside the signal strength range are not collected, so that data with low reliability (the farther the distance is, the lower the reliability of the distance calculated by the signal strength) can be avoided, and invalid calculated amount is reduced.
