Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 and figure 2 As shown, an intrinsically safe personnel identification locator based on dual-frequency RFID includes a housing on which an active RFID receiving area using PC material and a card swiping area using Bakelite material are arranged. The card swiping area For receiving passive RFID signals, the rest of the housing is made of lightweight stainless steel. A passive RFID module 1 and an active RFID module 2 are arranged in the housing, the passive RFID module 1 is arranged on the inner side of the card swiping area, and the active RFID module 2 is arranged on the inner side of the active RFID receiving area; The passive RFID module 1 is connected with the first processor 4, and the active RFID module 2 is connected with the first processor 4 through the second processor 5. In the present invention, the first p...

Abstract

The invention discloses an intrinsically safe type personal identification locator based on double-frequency RFID, which comprises a housing. A passive RFID module connected with a first processor and an active RFID module connected with the first processor through a second processor are arranged in the housing. The first processor is connected with a display screen and a storage circuit, and further provided with at least one RS485 bus interface. Both the first processor and the second processor are powered by an intrinsic safe power. The first processor outputs personal identification information after analyzing and comparing signals collected by the passive RFID and the active RFID module. The locator of the invention not only can accurately identify underground personnel, but also cantrack and position personnel in a region, in particular respectively uses independent processor to control the active RFID and the passive RFID without any interference, so the personal identification accuracy of locator is greatly improved.

Description

technical field [0001] The invention relates to a dual-frequency RFID mining intrinsically safe personnel identification system integrating wireless and wired communication, and belongs to the technical field of communication. Background technique [0002] Underground personnel identification in coal mines is an indispensable part of the personnel management system for mines. At present, the personnel identification system used in mines in China usually adopts RFID (Radio Frequency Identification, radio frequency identification), mainly in the following two types: [0003] One is to use active RFID. Since active RFID usually has its own power supply, it can actively transmit stable radio frequency signals without being activated by a reader. Therefore, active RFID has the characteristic of a long read and write distance. However, since the personnel identification system used in coal mines is generally installed at the wellhead, not only can the identification card informati...
