CN102855676A - Mining explosion-proof access control system - Google Patents

A mining explosion-proof access control system mainly comprises an explosion-proof door, a mining flameproof and intrinsically safe access controller, a mining explosion-proof access control card reader, a mining explosion-proof camera, a mining explosion-proof exit button, a mining intrinsically safe network switch, a mining encapsulated door lock, a mining intrinsically safe door magnetic sensor, door control system software, a remote computer host and attendance checking software, wherein the door control system software and the remote computer host are mounted in the access controller, and the attendance checking software is installed in the remote computer host. A whole access control system hardware structure adopts an explosion-proof design and meets the I-type and II-type explosion-proof electrical appliance standards in national regulation. When the mining explosion-proof access control system is used under a mine, the mining access control system can be used independently and can also be connected with the Ethernet to realize remote control and state monitoring on the mine.

The mine anti-explosion gate control system

Technical field

The mine anti-explosion gate control system is mainly used in access control, the attendance checking function in the necessary places such as mine down-hole transformer station, water plant.

Background technology

In the crucial place that most of mine down-holes have transformer station, water plant etc. to have the large number quipments property to need protection, the Main Means in existing mine is exactly the mode that explosion door is installed common door lock, as long as anyone has key to enter.Because the key of common door lock copies simply, after entering, personnel also without any record, caused losing in a large number of public property, brought very large economic loss to bargh.Gate control system can be authorized the related personnel, and the various information of accurate recording personnel turnover, can also realize the remote status monitoring, and the gate control system that development is fit to the mine down-hole use can solve the problems of present existence.

Summary of the invention

The present invention has mainly solved the Explosion-proof Design of each equipment of gate control system, and sets up the access control system that is fit to the mine down-hole use, has realized can implementing smoothly at various mine down-holes the control system of various gate functions commonly used.The present invention has adopted following technical scheme: access controller adopts the Flameproof and intrinsically safe design, and access-control card reader, explosion-proof video camera and the button of going out all adopt the flame-proof type design, and electromagnetic lock adopts the pouring type design, and the door magnetic inductor adopts the intrinsic safety type design; Be electrically connected by anti-explosion cable between each equipment.Access controller is adopted inside and stabilized voltage supply is housed is adopted the down-hole to exchange the 127V power supply to power, and the power supply of mine anti-explosion camera is controlled by the fuction output interface of access controller.Network interface on the access controller mainboard adopts the buffer circuit with network isolation transformer, has realized both can connecting flame-proof network switch, also can the intrinsic safety type network switch.

Description of drawings:

Accompanying drawing 1: mine anti-explosion gate control system structural drawing.

Embodiment:

The flame-proof type access controller is installed to the transformer station of mine down-hole or the assigned address of water plant, access-control card reader, explosion-proof video camera, the button of going out, electromagnetic lock and door magnetic inductor are respectively installed to the relevant position, use anti-explosion cable to connect each equipment to the corresponding explosion-proof wiring post of access controller;

Access controller is connected with mine anti-explosion camera by being connected with Ethernet switch under the mine by the explosion-proof wiring post with the network interface of network transformer, be arranged on the remote computer main frame of mine outside after the work attendance house arrest is installed, can carry out Long-distance Control and condition monitoring to access controller by this software, and can transfer at any time historical events information;

When enter card reader or the card reader of going out are read contactless card information, the gate control system software of controller is at first judged the data of contactless card, if the data of reading are the actual induction card information, access controller can be exported enabling signal to electromagnetic lock, box bolt is unclamped and kept for 30 seconds, the gate control signal that goes out of access controller resets after 30 seconds, and electromagnetic lock is again with door locking; No person, if the data that card reader is read are invalid contactless card information, access controller does not have enabling signal output, electromagnetic lock maintains the lock status.When access controller is received when going out button signal, access controller can be exported enabling signal to electromagnetic lock, box bolt is unclamped and kept for 30 seconds, and the gate control signal that goes out of access controller resets after 30 seconds, and electromagnetic lock is again with door locking;

When having the people to operate, gate control system opens the door, perhaps have when the people is improper to open the door, access controller can be connected the power supply of explosion-proof video camera and make a video recording, and sends information to the remote computer main frame, and the while vision signal also is transferred to the remote computer main frame by Ethernet and preserves;

This mine anti-explosion gate control system can be brought very large help to the safeguarding of assets in existing mine, simultaneously IT application in management, the modernization in mine is also had greatly improved.
