Abstract
The invention relates to an explosion suppression type access control card reader for a mine. The explosion suppression type access control card reader for the mine is characterized in that the access control card reader is designed into an explosion suppression type and meets standards of I-type and II-type explosion-proof electric apparatuses according to national regulations; when being used under the mine, the access control card reader for the mine is taken as an identity recognition apparatus of the an access control system, and forms the access control system together with devices including a mine controller, an electromagnetic lock and the like; the access control card reader for the mine mainly comprises an access control card reader circuit board, an explosion suppression cavity, an explosion-proof binding post and a sealing rubber ring; and a card reading region at the front face of the explosion suppression cavity is made of toughened glass material, other parts of the explosion suppression cavity are made of stainless steel materials, and the access control card reader circuit board is mounted in the explosion suppression cavity.
Description
Technical field
The flame-proof mine access-control card reader mainly is applicable to have damp (methane mixture, coal dust) place with other under the coal mine, is the main input equipment of access control system, is mainly used in reading the contactless card data and is sent to access controller.
Background technology
Because mine electrical appliance equipment is to explosion-proof having relatively high expectations, below the present mine, aspect access control, also rest on the stage that comparatively falls behind, a lot of inconvenience of bringing for the information system management in mine, also caused the phenomenon of a large amount of stolen properties, development mining intelligent access control system brings large increase can for information system management and the downhole anti-theft of existing bargh.This flame-proof mine access-control card reader must cooperate mine anti-explosion gate inhibition controller to use together as the identity recognition device of the mining access control system of our company's invention.
Summary of the invention
The present invention has mainly solved to be possessed the normal procedure intelligent access-control card reader and can guarantee that card reader can read the information of contactless card, has reached again I class and the II class standard of explosion-proof electric apparatus national regulation, can have the mine down-hole of requirement of explosion proof to use various.The present invention has adopted following technical scheme: access-control card reader adopts the flame-proof type structural design, mainly comprise the access-control card reader circuit board, the flame proof cavity, the explosion-proof wiring post, O-ring seal forms, the access-control card reader circuit board is installed in the flame proof cavity, the explosion-proof wiring post is installed between flame proof cavity and the connection jaws, the interface of access-control card reader circuit board is connected on the explosion-proof wiring post by electric wire, the Card Reader zone in flame proof cavity explosion-proof chamber body front adopts the tempered glass material to make, other parts adopt stainless steel, the access-control card reader circuit board also comprises data storage circuitry take single-chip microcomputer as central processor unit, the RF circuit, communication interface circuit and led state show.
Description of drawings:
Accompanying drawing 1: flame-proof mine access-control card reader electrical structure diagram;
Accompanying drawing 2: flame-proof mine access-control card reader outside drawing.
Embodiment:
The access-control card reader circuit board is installed in the flame proof cavity, and the explosion-proof wiring post is installed between flame proof cavity and the connection jaws, and each connection terminal of access-control card reader circuit board interface is connected by electrical wiring to respectively on interior each terminal of explosion-proof wiring post of flame proof cavity.Under mine or other explosion-proof places when using, the explosion-proof wiring post of explosion-proof card reader connection jaws is connected on the explosion-proof access controller control connection jaws by anti-explosion cable;
The central processor unit of access-control card reader circuit board is by SPI data bus connection data memory circuit, RF circuit and communication interface circuit, and the outlet of the function number of central processor unit is connected to the led state display circuit.Mine anti-explosion gate inhibition card reader is connected to explosion-proof access-control card reader by explosion-proof wiring post and anti-explosion cable, behind the plugged, the LED lamp of led state display circuit is in and extinguishes state under the normal condition, and the RF circuit carries out the transmission of detection signal and the reception of contactless card data by antenna.When having contactless card to be in the effective Card Reader distance of mine anti-explosion gate inhibition card reader, the RF circuit by antenna reception to contactless card information be sent to central processor unit through the SPI data bus, central processor unit arrives explosion-proof access controller by communication interface circuit with the contactless card information conveyance, explosion-proof access controller is judged through the information to contactless card, if effective contactless card, explosion-proof access controller can send the signal of normally swiping the card to explosion-proof access-control card reader, central processor unit is after receiving the signal of normally swiping the card, export corresponding function and be indicated to the led state display circuit, this moment, the LED green indicating lamp was lighted, and extinguished after the second; If invalid contactless card, explosion-proof access controller can send the improper signal of swiping the card to explosion-proof access-control card reader, and central processor unit is exported corresponding function and is indicated to the led state display circuit after receiving the improper signal of swiping the card, this moment, the LED red led was lighted, and extinguished after the second.
