Indoor article management equipment based on UWB positioning

Abstract

The invention relates to the technical field of article management equipment, in particular to indoor article management equipment based on UWB positioning. The indoor article management equipment comprises a cabinet body, a cavity, a drawer, a handle and a controller. a storage box is placed on the drawer; a first groove is formed in the cabinet body; an electromagnet, a reset spring and a stop block are arranged in the first groove; the electromagnet and the reset spring are fixedly connected with the first groove, the electromagnet is sleeved with the reset spring, and the other end of the reset spring is fixedly connected with the stop block; and the stop block can extend out of the first groove. The storage box is supported through the stop block, then the stop block is attracted by the electromagnet, the storage box falls onto the drawer, and workers take out documents, so that the purpose of hiding the documents after the documents are stored is achieved, irrelevant personnel are prevented from being in contact with the documents,and the documents are stored more safely; and meanwhile, the workers can find the documents conveniently, so that the practicability of the indoor article management equipment is enhanced.

Description

technical field [0001] The invention relates to the technical field of article management equipment, in particular to an indoor article management equipment based on UWB positioning. Background technique [0002] UWB positioning is based on ultra-wideband technology and is a wireless carrier communication positioning technology. UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception ability, and high positioning accuracy. Therefore, prisons, police Bureaus, detention centers and other places use UWB positioning to manage items and keep important evidence and items; however, the existing item management equipment cannot hide the stored items when storing items, so the protection of important evidence is insufficient. This makes it possible for irrelevant personnel to have access to the evidence, and at the same time cannot locate the evidence, making it inconvenient for s...

[0002] UWB positioning is based on ultra-wideband technology and is a wireless carrier communication positioning technology. UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception ability, and high positioning accuracy. Therefore, prisons, police Bureaus and detention centers use UWB positioning to manage items and keep important evidence and items; however, the existing item management equipment cannot hide the stored items when storing items, so the protection of important evidence is insufficient. This makes it possible for irrelevant personnel to have access to the evidence, and at the same time cannot locate the evidence, making it inconvenient for the staff to find the evidence

[0003] For example, a Chinese patent with the application number CN201922186339.6 discloses a management cabinet based on RFID technology to accurately locate items, including a main body bracket, a reader is installed on the main body bracket, and a cavity is opened in the rear side wall of the main body bracket body, a motor is installed on the rear inner side wall of the cavity, the output end of the motor is fixedly connected to a transmission shaft, the other end of the transmission shaft is fixedly sleeved with a cylindrical cam, and the protruding end of the transmission shaft is fixedly connected to On the side wall off-center of the triangular runner, the triangular runner is connected in contact with the limit frame, the outer wall of the limit frame is fixedly connected with a connecting column, and the other end of the connecting column is fixedly connected with a sliding The sleeve is slidingly sleeved with a push rod in the sliding sleeve, one end of the push rod is fixedly connected to a connecting rod, and the other end of the connecting rod is rotatably connected to a sliding rod; the bottom plate of this technical solution moves intermittently back and forth, In this way, the bottom plate can move forward, backward, up and down to achieve the purpose of convenient pick-up; however, this technical solution cannot hide the stored items, and irrelevant personnel can touch the items, which in turn causes the limitations of the solution.
