Embodiment Construction

[0025] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0026] The embodiment of the present invention provides a method for monitoring precious metals in a bank vault. In order to achieve precise positioning of precious metals, at least three positioning base stations are set in the bank vault, and each positioning base station is located at a different location. Set with UWB positioning label.

[0027] like figure 1 As shown, the method includes the following steps 101 to 104:

[0028] Step 101: Obtain the receiving time of the positioning data frame of the target precious metal detected by the positi...

Abstract

The invention discloses a bank vault precious metal monitoring method and device, and relates to the technical field of Internet of Things, at least three positioning base stations are arranged in a bank vault, the positions of the positioning base stations are different, and a UWB positioning tag is arranged on each precious metal in the vault. The method comprises the following steps: acquiring the receiving time of a positioning data frame of a target precious metal detected by a positioning base station, wherein the positioning data frame is sent by a UWB positioning tag arranged on the precious metal; calculating target position information of the UWB positioning tag according to the receiving time obtained from any three positioning base stations in all the positioning base stations; comparing the target position information with stored preset position information; and if yes, determining that the position of the noble metal is not changed. Precise positioning of precious metal can be achieved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method and device for monitoring precious metals in bank vaults. Background technique [0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Precious metal trading is an important part of commercial bank transactions. Precious metals used for trading are usually kept in the bank's vault. Bank managers are worried that precious metals will be artificially replaced or stolen during the process of safekeeping, which has certain risks. To reduce the risk of precious metal theft, it is necessary to locate precious metals. [0004] The traditional positioning technology determines the position of the object according to the strength of the positioning signal, but the strength of the signal is easily a...
