Embodiment
The embodiment of the utility model provides a kind of gate inhibition's recognition system of the REID based on Internet of Things; As shown in Figure 1; Comprise remote server 1, radio frequency receiving front-end circuit 2, check code reads and sending module 3 and gate inhibition's card 4; The radiofrequency signal output terminal of radio frequency receiving front-end circuit 2 reads with check code and the RF signal input end of sending module 3 is connected; Check code reads and the check code data output end of sending module 3 is connected with the check code data input pin of remote server 1, is provided with in gate inhibition's card 4 and remote server 1 corresponding check sign indicating number generation module, and radio frequency receiving front-end circuit 2 and gate inhibition's card 4 are all based on the Zigbee agreement.
Concrete; Zigbee is an a kind of low-power consumption territory fidonetFido based on the IEEE802.15.4 standard; Technology according to this agreement regulation is the wireless communication technology of a kind of short distance, low-power consumption, is characterized in closely, low complex degree, self-organization, low-power consumption, low data rate, low cost.Mainly be suitable for control and remote control field automatically, can embed various device.The frequency of operation of Zigbee protocol module: 2.4GHz-2.5GHz ISM microwave section; Decipherment distance: effectively decipherment distance can reach 15-150m; Recognition speed: the highest recognition speed can reach 200 kilometers/hour; Recognition capability: discern 200 labels simultaneously.Radio frequency receiving front-end circuit 2 all is based on the Zigbee agreement with gate inhibition's card 4, therefore in radio frequency receiving front-end circuit 2 and gate inhibition's card 4, all is provided with the Zigbee protocol module, and its circuit diagram is as shown in Figure 2.The circuit diagram of radio frequency receiving front-end circuit 2 is as shown in Figure 3.
When the user uses the gate inhibition's card have the Zigbee protocol module during near card reader; After being arranged on radio frequency receiving front-end circuit in the card reader and sensing gate inhibition's card; Produce electric current and electric current is provided for Zigbee protocol module and check code generation module in gate inhibition's card; After the check code generation module produces random number; Send to radio frequency receiving front-end circuit through the Zigbee protocol module, the Zigbee protocol module in the radio frequency receiving front-end circuit 2 sends to the random number that receives that check code reads and sending module 3, is read and sending module 3 sends to remote server 1 with random number by check code.In remote server 1, be provided with the check code generation module in the random number create-rule shared; After remote server 1 receives the random number that check code reads and sending module 3 sends; Can verify that if meeting rule then verifies success, remote server 1 notice check code reads and sending module 3 is opened gate inhibition's lock through the random number create-rule; If do not meet then authentication failed of rule, the gate inhibition can not open.
Store the random number create-rule of sharing with far-end server in the said check code generation module, and when each radio frequency receiving front-end circuit received RF signal, generate random number.
The technical scheme that adopts this embodiment to provide is communicated by letter with remote server through check code, has higher security, and can realize that the gate inhibition discerns, and is user-friendly in larger distance based on gate inhibition's card of Zigbee agreement.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claims.
