Embodiment
Below in conjunction with accompanying drawing, just above-mentioned being described further with other technical characteristic and advantage of the present invention.
Referring to Fig. 2, is the structural representation of card reader management system one specific embodiment of the present invention.Different from the design of routine, card reader management system of the present invention adds and the interface of computing machine and the Energy control to safety control module.Generally, the power supply of safety control module is in closed condition.The card seeking order that computing machine sends directly arrives microcontroller, microcontroller sends card seeking order again to radio-frequency module, when radio-frequency module has return data (when having I.D. in antenna effective area), the power supply of safety control module opened again by microcontroller, carries out normal Card Reader operation.After Card Reader, closed safe control module power supply.In whole process, safety control module is in "on" position in a flash only at Card Reader, is in off-position At All Other Times.Therefore, the power consumption that can reduce whole card reading module nearly 50%.
Meanwhile, in conjunction with the control of computing machine to whole card reading module power supply, the power consumption of system can greatly be reduced.In addition, when computing machine can not cut out card reader power supply (time as abnormal in the appearance of Card Reader software), judge whether that not receiving instruction carrys out closed safe control module for a long time by microcontroller, and make radio-frequency module and microcontroller enter low power consumpting state, minimum to make card reading module electric current drop to.
Continuing to consult Fig. 3, is the structural representation of another specific embodiment of card reader management system of the present invention.Whether the present embodiment adds photoelectric sensor switch on the basis of Fig. 2, have certificate card (I.D.) to be positioned in Antenna Operation region for induction.
When not having I.D. in territory, antenna card-reading zone, the power supply of microcontroller closed safe control module and radio-frequency module, whole module is in holding state.When photoelectric sensor switch detect in Card Reader region have I.D. time, send a signal to microcontroller, the power supply of safety control module and radio-frequency module opened by microcontroller, start Card Reader.Card reading module is only in running order in Card Reader moment, and be all in holding state (standby current is 10% or lower of working current) At All Other Times, therefore, this design significantly can reduce the average operating current of whole module.Photoelectric sensor switch can adopt reflection-type optoelectronic switch, regulates the distance of reaction of optoelectronic switch consistent with the Card Reader distance of antenna.
Fig. 4 is the process flow diagram of card reader management method one specific embodiment of the present invention.As shown in Figure 4, card reader management method of the present invention specifically comprises the following steps:
The Card Reader software be arranged in computing machine sends Card Reader order;
After microcontroller receives Card Reader order, whether optoelectronic induction module has sensed that certificate exists;
If have certificate to exist near optoelectronic induction module senses, radio-frequency module and safety control module are set to "on" position from off-position by microcontroller, start to read certificate data; If optoelectronic induction module has certificate near not sensing, radio-frequency module and safety control module are set to off-position by microcontroller, stop reading certificate data;
When Card Reader software does not send Card Reader order in the given time, described radio-frequency module and described safety control module can be set to off-position by microcontroller automatically, thus avoid electric energy loss.
More than illustrate just illustrative for the purpose of the present invention, and nonrestrictive, and those of ordinary skill in the art understand; when not departing from the spirit and scope that following claims limit, many amendments can be made, change; or equivalence, but all will fall within the scope of protection of the present invention.
