Described access control equipment 20 is constantly in low-power consumption mode when not receiving detection signal, under low-power consumption mode, described access control equipment 20 consumes energy minimum, only supports the detection signal that receiving detection device 10 sends, and when receiving detection signal, it is switched to normal mode of operation from low-power consumption mode.Access card 30 is constantly in low-power consumption mode when not receiving low frequency card seeking signal, under low-power consumption mode, access card 30 consumes energy minimum, only support to receive the low frequency card seeking signal that described access control equipment 20 sends, and when receiving low frequency card seeking signal, be switched to normal mode of operation from low-power consumption mode, i.e. access card 30 is activated.
The trigger input circuit of described access control equipment 20 is after receiving the detection signal that detection device 10 sends, described access control equipment 20 is switched to normal mode of operation from low-power consumption mode, and activate low-frequency channel, low-frequency channel described in main controller controls sends and comprises the 125KHz low frequency card seeking signal adding confidential information, to search and to wake up the access card 30 near described access control equipment 20 up.After the low-frequency channel on access card 30 near described access control equipment 20 receives described low frequency card seeking signal, described access card 30 is activated, described low frequency card seeking signal is decrypted by the microcontroller being arranged on described access card 30 according to preset decryption mechanisms, and after successful decryption, verify the data field in described low frequency card seeking signal, after checking successfully, the high-frequency circuit on described access card 30 sends with the frequency of 868-915KHz and comprises the high frequency response signal adding confidential information.When not having access card 30 to respond near described access control equipment 20, described master controller is attempted the low-frequency channel of access control equipment 20 again and is sent low frequency card seeking signal, and at most attempt three times, if the high-frequency circuit of access control equipment 20 does not all receive the response signal that access card 30 sends for three times, described access control equipment 20 reenters low-power consumption mode；If once receiving the high frequency response signal that access card 30 sends during the high-frequency circuit of access control equipment 20, the most described master controller carries out follow-up deciphering according to described high frequency response signal and determines the operation of enabling authority.
When an access control equipment 20 is provided with A encryption mechanism, it is possible to be provided with corresponding A decryption mechanisms on the access card 30 by the management and control of described access control equipment 20；When described access card 30 is provided with B encryption mechanism, described access control equipment 20 is provided with corresponding B decryption mechanisms.Wherein, described A encryption mechanism can be identical with described B encryption mechanism, it is also possible to different.
The gate control system that the utility model proposes, when access control equipment 20 or access card 30 do not receive any signal, it is in low power mode of operation, when receiving signal, it is switched to normal mode of operation from low-power consumption mode, and carry out follow-up operation, reduce access control equipment 20 or access card 30 energy consumption at one's leisure, and when access control equipment 20 sends low frequency card seeking signal to access card 30, first data are encrypted, then launching with low frequency card seeking signal, enhancing the safety and reliability communicated between access control equipment 20 with access card 30.
Further, proposing this utility model gate control system the 3rd embodiment based on above-mentioned second embodiment, in the present embodiment, described high frequency response signal includes card number and the authority information of access card 30；Described access control equipment 20 is additionally operable to:
Receive described high frequency response signal and decipher, to obtain the card number of described access card 30, authority information；
After the high-frequency circuit of described access control equipment 20 receives the high frequency response signal that access card 30 sends, the master controller of described access control equipment 20 obtains described high frequency response signal, and according to preset decryption mechanisms, described high frequency response signal is decrypted, after successful decryption, obtain card number and the authority information of described access card 30.The condition that when authority information of described acquisition includes physical label corresponding to gate inhibition that the access card 30 that described card number is corresponding can be opened and opens each described gate inhibition, needs meet, described condition can be to limit access card 30 just to open in stipulated time section and specify gate inhibition.
According to preset access card information and the card number of described acquisition, authority information, it is judged that whether described access card 30 has the enabling authority opening the gate inhibition associated with described detection device 10；
In the authority information of described acquisition, the authority determined by the physical label of described card number and described gate inhibition, consistent with the authority determined by the physical label of described card number and described gate inhibition in described access card information and when meeting door-opening condition, determine that described access card 30 has the enabling authority opening the gate inhibition associated with described detection device 10.
When judging the enabling authority of described access card 30, described master controller, according to the communication path at described detection signal place, determines the physical label of the gate inhibition associated with described detection device 10.When the card number of the described access card 30 obtained is present in described preset access card information, and the authority determined by described physical label in the authority information of described acquisition, consistent with the authority determined by described card number and described physical label in described access card information and when meeting door-opening condition, determine that described access card 30 has the enabling authority opening the gate inhibition associated with described detection device 10.
When the card number of the described access card 30 obtained is not in preset access card information, described access card 30 lack of competence opens the gate inhibition associated with described detection device 10；When the card number of the described access card 30 obtained is present in preset access card information, but in the authority information of described acquisition and preset access card information, when the authority determined by described card number and described physical label is inconsistent or is unsatisfactory for door-opening condition, described access card 30 also lack of competence opens the gate inhibition associated with described detection device 10.After described access control equipment 20 is opened gate inhibition according to the authority of described access card 30 or sent lack of competence warning signal, described access control equipment 20 reenters low-power consumption mode.
The gate control system that the utility model proposes, use low frequency activation, high-frequency communication, the communication mode of double-encryption, and under the card number and current gate inhibition of access card 30 authority information of described access card 30, consistent with card number authority information under described gate inhibition described in preset access card information and when meeting door-opening condition, determine that described access card 30 has permission and open described gate inhibition, compared with only by the way of card number coupling can open gate inhibition, enhance the safety of access control.
