Smart card read-write device with temperature sensing function of the present utility model is specially adapted to access control system, this moment, described upper opertaing device was gate inhibition's opertaing device, specifically the temperature sensing module can be installed in the appropriate location, doorway, when the card user swipes the card, also detect the body temperature at its forehead or other position, have only when by Card Reader being legal and card user's body temperature in predetermined temperature range the time, just send the control signal of opening the door.As seen, in the scheme of the present utility model smart card read-write capability and temperature detecting function are combined, can by its communication interface and different upper opertaing device connections, thereby realize different control function according to different needs.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram that has the smart card read-write device of temperature sensing function in the utility model;
Fig. 2 is the circuit diagram of a preferred embodiment of the utility model.
Embodiment
Principle of the present utility model as shown in Figure 1, its element microprocessor 1, to the module for reading and writing 2 that outside intelligent card 21 is read and write, be used for microprocessor 1 is connected to the serial communication interface 4 of upper opertaing device 22, this communication interface can be RS232 interface or RS485 interface.The module for reading and writing 2 here is the contact type intelligent card module for reading and writing, so also comprise the antenna 3 that is used to launch carrier wave and emission modulation signal and receives the outside intelligent card feedback signal.The intelligent card chip that is provided with inductive coil in the corresponding intelligent card and is attached thereto.Certainly, module for reading and writing wherein can also be the contact module for reading and writing.As can be seen from Figure 1, wherein also comprise the temperature sensing module 5 that is connected with microprocessor 1; The temperature data that intelligent card data that microprocessor 1 in this device can be imported according to module for reading and writing 2 and temperature sensing module 5 are imported, upload the required data of corresponding control by communication interface 4 to upper opertaing device 22, for example the sequence number of smart card, measured temperature data etc.This smart card read-write device combines smart card read-write capability and temperature detecting function, thereby can be according to different needs, by its communication interface and different upper opertaing device connections, to realize different control function.
As can be seen from Figure 1, also can set up the status indicator lamp 6 that is connected with microprocessor 1, LED light for example, thus can indicate current working state by wigwag; Or set up hummer 7, thereby can indicate current working state by voice signal.In addition, also can set up the display 8 that microprocessor 1 connects, this display can be used for the smart card information that the measured temperature of displays temperature sensing module 5 and/or module for reading and writing 2 are read.
Be illustrated in figure 2 as the circuit diagram of a preferred embodiment of the utility model.
Wherein, microprocessor adopts the SST89E564RD single-chip microcomputer, and it mainly is responsible for receiving the data that sended over by temperature sensing module and RC500 module, the communication relation between processing and the upper opertaing device, and the duty of state of a control indicating circuit.
Module for reading and writing adopts the RC500 module, it is used to carry out the order of the ISO14443TYPEA that is sent by microprocessor, again by antenna emission carrier and modulating signal, thus the read-write operation that MAIFARE card (a kind of special intelligent card that PHILIPS company produces) is correlated with.Because the output terminal impedance of RC500 module is 50 ohm,, thereby can launch maximum energy so antenna also is designed to 50 ohm.
The temperature sensor U3 in the upper left corner be responsible for to measure human body forehead temperature, and it is converted to corresponding data sends to microprocessor.This temperature sensor comprises the single-chip microcomputer (not drawing in the drawings) of an infrared contactless probe and treatment temperature data.When infrared non-contact probe detects different human body temperature, can export different voltage, it is very faint that the voltage of this output simultaneously changes when different temperature, so need it be amplified by discharge circuit, carry out himself single-chip microcomputer of input after the analog to digital conversion again, judge the temperature of tested human body by its single-chip microcomputer according to different input values again, and these data are sent to microprocessor SST89E564RD.
