Problems solved by technology

However, the long working distance also brings new problems: in densely populated places at the wellhead, a large number of cards are read into the card reader at the wellhead at the same time. It matches the card holder, whether one person carries multiple cards, etc. Therefore, many mines have to use multiple methods such as personnel positioning, clocking in and attendance, or entry and exit signatures at the same time, so that the staff carry two cards at the same time to obtain more accurate information. Personnel location information

Embodiment Construction

[0038] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0039] The active identification card provided by the invention adopts a card-type structure (identity card size, 5mm thick), small in size, light in weight, and easy to carry. At the same time, it is equipped with LED indications such as working status and battery undervoltage, so that the cardholder can know at any time The status of your own card. The card contains a rechargeable battery, which can be charged through wireless charging, without the need to replace or disassemble the battery, and is easy to use.

[0040] Such as figure 1 As shown, the identification card includes a resonant circuit II, a rectifier voltage regulator, a charge management circuit,...

Abstract

The invention provides an active identification card with a card-type structure, which has a dual-frequency emission function and can sense low-frequency excitation signals, and combines the functions of an attendance card and a positioning card on one identification card to realize two cards in one. . The card contains a rechargeable battery that can be charged wirelessly, and has LED indicators such as working status, battery undervoltage, and battery charging, so that the cardholder can know the status of his card at any time. The active identification card includes resonant circuit II, resonant circuit I, limiter circuit, rectifier regulator, charging management circuit, rechargeable battery, CPU, identification card ID transmitter and CPU voltage regulator. The invention also discloses a control method of the active identification card and an attendance locating system using the card.

Description

technical field [0001] The invention relates to the communication field, in particular to an active identification card used for underground personnel positioning and wellhead attendance checking, a control method of the active identification card and an attendance positioning system using the active identification card. Background technique [0002] The downhole operator management system usually includes wellhead attendance system and downhole personnel positioning system. In the wellhead attendance system, the personnel who go down the well manually swipe their cards on the attendance machine (card reader) to obtain the exact time when each person enters and exits the well, and can count the total number of downhole personnel. Due to the short distance between the identification card and the card reader, the identification cards are mostly passive cards. This system is convenient for supervision and avoids the phenomenon of going down the well without a card or one perso...
