Abstract
The utility model discloses a multi-radio frequency card door control reader. The multi-radio frequency card door control reader comprises a master controller, a door lock driving circuit, an alarm device, read-write chips and a time circuit, wherein a plurality of read-write chips are provided, the output ends of the read-write chips are respectively connected with the input end of the master controller, the control output end of the master controller is connected with the control input end of the door lock driving circuit, and the output end of the master controller is connected with the input end of the alarm device. According to the utility model, with the plurality of read-write chips and the time circuit, reading speed of the door control reader is improved, the master controller is protected from endless loop phenomenon caused by instantaneously receiving the read-write requests of the plurality of read-write chips, and the door control reader has good compatibility and simple structure.
Description
Technical field
The utility model relates to a kind of gate inhibition's reader, relates in particular to a kind of gate inhibition's reader of many radio-frequency cards.
Background technology
Gate control system is that the gateway of important area or passage is managed and the system of controlling.Along with social development, it has been not limited to the simple management to door lock or key, but the new-modernization safety management system of collection automatic identification technology and modern management technique and one, become a part very important in security system, the occasions such as middle intelligent building, office, hotel are widely used.
Manufacturer's difference of existing gate inhibition's reader, the RF frequency can read is different, poor compatibility, even if can read, need in primary controller, carry out the conversion of corresponding frequencies with identification user's information, reading efficiency is low, can not adapt to the simultaneous situation of multiple radio-frequency card.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is just to provide in order to address the above problem, gate inhibition's reader of many radio-frequency cards that compatibility is good.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises primary controller, lock drive circuit, warning device, local storage, read-write chip and time circuit, described read-write chip is multiple read-write chip, the output terminal of described read-write chip is connected with the input end of described primary controller respectively, the triggering output terminal of described time circuit is connected with the triggering input end of described microprocessor, the control output end of described primary controller is connected with the control input end of described lock drive circuit, the output terminal of described primary controller is connected with the input end of described warning device, the FPDP of described local storage is connected with the FPDP of described primary controller.
Particularly, be provided with serial interface circuit on described primary controller, described serial interface circuit output end is connected with the input end of PC.
Further, described warning device is acoustic-optic alarm.
Particularly, described read-write chip is RFID read-write chip.
The beneficial effects of the utility model are:
The utility model has improved the reading speed of gate inhibition's reader by multiple read-write chip and time circuit, avoid primary controller moment to receive the read-write requests of multiple read-write chip and the phenomenon of endless loop occurs, compatible good, simple in structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises primary controller, lock drive circuit, warning device, local storage, read-write chip and time circuit, described read-write chip is multiple read-write chip, the output terminal of described read-write chip is connected with the input end of described primary controller respectively, the triggering output terminal of time circuit is connected with the triggering input end of microprocessor, the control output end of described primary controller is connected with the control input end of described lock drive circuit, the output terminal of described primary controller is connected with the input end of described warning device, the FPDP of described local storage is connected with the FPDP of described primary controller.
On described primary controller, be provided with serial interface circuit, described serial interface circuit output end is connected with the input end of PC, and convenient to the gate control system renewal of upgrading, described warning device is acoustic-optic alarm, and read-write chip is RFID read-write chip.
In the present embodiment, radio-frequency card is near the utility model time, the first read-write chip is the read-write chip of 13.56MHZ, the second read-write chip is the read-write chip of 12.26MHZ, when using the radio-frequency card identical with read-write frequency to contact with the second read-write chip with the first read-write chip, time circuit on primary controller reads sequence to the first read-write chip and the second read-write chip successively, avoids primary controller moment to receive the read-write requests of multiple read-write chip and the phenomenon of endless loop occurs.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
