Embodiment Construction

[0010] In order to further understand the structure, features and other purposes of the present invention, the attached preferred embodiments are now described in detail with accompanying drawings as follows. The embodiments described in the accompanying drawings are only used to illustrate the technical solutions of the present invention and are not limiting this invention.

[0011] like figure 1 as shown, figure 1 It is a flow chart of the walkie-talkie indoor positioning method of the present invention; the walkie-talkie indoor positioning method comprises the following steps:

[0012] Step S1): An RFID card reader and an acceleration sensor are connected to the CPU in the walkie-talkie through a peripheral interface, that is, the RFID card reader and the acceleration sensor are built into the walkie-talkie. Among them, the RFID card reader is used to determine the initial static position, and the acceleration sensor is used to measure the instantaneous acceleration and p...

Abstract

The invention provides an interphone indoor positioning method based on an acceleration sensor and an RFID. The method comprises the steps that an RFID card reader and the acceleration sensor are externally connected to a CPU in an interphone; the RFID card is fixed, and the interphone is tightly attached to the RFID card; the RFID card reader in the interphone reads the position information of the RFID card, and the CPU sets the current initial speed of the interphone as 0; when the RFID card reader successfully reads the RFID card, the CPU immediately starts to set the coordinate in the interphone to be the same as the coordinate point in the RFID card, the acceleration values obtained by the acceleration sensor are immediately and continuously collected, the acceleration values are subjected to integration twice on time to obtain the displacement of the interphone, and the real-time position of the interphone is calculated; and the real-time position is transmitted to a monitoring system through the interphone. The interphone indoor positioning method enables the indoor positioning layout to be simpler, just needs one RFID card least , and compared with Bluetooth and UWB positioning, is lower in cost and is simpler to install and set.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to an indoor positioning method for walkie-talkies based on acceleration sensors and RFID. Background technique [0002] With the progress of society and the gradual increase in the awareness of personal safety of staff. For many high-risk occupations, more protection and monitoring measures are required to ensure the safety of personnel. Most of the current indoor positioning is based on Bluetooth or UWB. However, the high cost and complex construction lead to relatively unsatisfactory acceptance of indoor positioning. Contents of the invention [0003] In order to solve the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide an indoor positioning method for walkie-talkies based on acceleration sensors and RFID, so as to overcome the defects in the prior art. [0004] In order to achieve the above object, the present inv...
