The locator 10 is arranged in the preset space 11 according to a preset rule, the first excitation signal is a 125KHz low-frequency wake-up signal, the locator 10 periodically emits the first excitation signal outwards according to a preset time interval, and the information such as the identification code of the locating device is modulated by the first excitation signal. In some embodiments, the frequency of the first excitation signal is not limited to 125 KHz.

The layout of the positioner 10 is related to the configuration of the preset space, the transmitting power of the positioner, the positioning accuracy of the system, and the like. Taking a preset space 11 as a room as an example, the locator 10 is fixedly installed on a wall and/or a roof of the room, and an excitation range of the locator 10 is calculated according to the transmission power of the locator 10 with the locator 10 as a center of a circle.

Assuming that the locators 10 of the same specification are arranged in a room, the number of the locators 10 of the specification required to be arranged in the room can be calculated according to the excitation range of the single locator 10 and the area of the room.
