Description

Gate inhibition's monitoring arrangement of coming in and going out

The utility model relate to the monitoring arrangement that a kind of gate inhibition comes in and goes out and the back instant playback of marching into the arena go in the device of the legal stop of personnel, be particularly related to and utilize a kind of storage card (IC-card) to come gate inhibition's discrepancy is monitored, writes down and the instant position of the monitoring arrangement that last input gate inhibition comes in and goes out and the temporal information at that time of showing on the reader device display that personnel wore, or the display requirement response message, be a kind of electronic monitoring and security device.

In the various occasions of current commodity society, often need do strict monitoring, the turnover personnel are carried out status differentiation, confirm and supervision the control area.

Rely on manual type traditionally and finish monitor task, be equipped with key separately for example for the people of certain identity, perhaps according to the visual method of Security Services to the forbidden zone.Though adopt camera technique in addition, security devices commonly used such as infrared ray investigation device make up the above-mentioned task of finishing, but in some application, except distinguishing identity, also to authorize the control of stratum, know to declare whether the user has the right to use this equipment, and the extent of competence of control user when this equipment of use.But in some occasion, also need guarantee the people that whether really authorized by or enter this district, in a personnel activity's observation system, because of sometimes when the door of guarded region is opened, if when having the people of mistake to enter at that time more, be difficult to monitor the people who enters subsequently and whether authorized and enter and when enter this district.

The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of and can control better or supervisory work, implement to check whether to have authorized to rest in this zone to reach to personnel movable in monitored space, to utilize the display device of being worn really.

The control device that gate inhibition of the present utility model comes in and goes out comprises microprocessor, program storage, data-carrier store, input/output interface circuit, clock circuit, keyboard, display; Described microprocessor connects a storage card reader by input/output interface circuit, has a draw-in groove of allowing that storage card inserts on the storage card reader, and the draw-in groove of allowing the storage card insertion of a split.Microprocessor has functions such as input, output, record, calculating, judgement, control, the data that can read in according to storage card reader, the condition that contrast is set, the switching of control door lock, and the Position Number of this device and time at that time write in the storage card, also the out of Memory after the networking can be write in the storage card.

The control device that gate inhibition of the present utility model goes out/goes into monitors the gate inhibition by data in the storage card (or claiming to distinguish card or IC-card) is distinguished to control, so its control device disposes storage card reader, data in the readable card taking, also can write card to data gets on, and storage card can store relevant identification personnel's data (for example personal identification number), and other is about data such as these personnel, these personnel's discrepancy situation for example, authorize stratum, go out the indegree record, when the microprocessor in the control device reads the data of specific function on this storage card, can determine whether start specific working routine.

Above-mentioned storage card reader has two storage card read-write slots, one is used when entering, one is used when leaving, and can read and/or write the data in a plurality of storage cards simultaneously, and this scheme is particularly useful for the place of gate inhibition's control and stratum's authorization control; Data of storing in the above-mentioned storage card or data preferably include the personal identification number data, can set one except inserting card, also need the scheme that could be confirmed by key feeding cipher.

The utility model also provides a kind of simple memory card reader and device shown is arranged, and it can be worn at staff's front or sack, can show simultaneously the control device numbering that the gate inhibition of last typing goes out/goes into and the time of typing at that time.Above-mentioned memory card reader has single storage card Card Reader slot, can once hold unique storage card data that reads, and the control device numbering that the gate inhibition of the last typing of demonstration goes out/goes on display screen simultaneously and the time of typing at that time; Also can show other information of typing, for example calling information etc.

First kind of control device that the gate inhibition goes out/goes into of the present utility model, simple and reasonable for structure, can be effectively to the turnover personnel carry out identity validation, cryptographic core to, authorize stratum to confirm, write down each personnel or each gate inhibition's turnover data.And second kind of portable Card Reader of the present utility model and display device structure are simple, rationally more can show gate inhibition's numbering of its typing effectively, time at that time and the situation that goes out/go into.
