Fig. 1 is the process flow diagram of the capacitive sensing method of a kind of Non-contact Media Reader provided by the present invention;
Fig. 2 is the module map of a kind of Non-contact Media Reader provided by the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The embodiment of the invention provides a kind of capacitive sensing method of Non-contact Media Reader, to reduce the energy resource consumption of Non-contact Media Reader.Because there is multiple mode in the specific implementation of the capacitive sensing method of above-mentioned Non-contact Media Reader, is elaborated below by specific embodiment:
See also shown in Figure 1ly, shown in Figure 1 is a kind of capacitive sensing method of Non-contact Media Reader, comprising:
Step S11, power up when starting when described Non-contact Media Reader, the duty of the processor of described Non-contact Media Reader is converted to dormant state;
Wherein, when Non-contact Media Reader powers up startup, be in running order under the processor normal condition of Non-contact Media Reader, but do not having non-contact IC card near under the situation of Non-contact Media Reader, the power consumption of processor is just nonsensical fully.So when Non-contact Media Reader powered up startup, just the duty with processor was converted to dormant state, with saves energy.
Step S12, judge in the preset range of described Non-contact Media Reader whether have non-contact IC card, if then enter step S13; Otherwise, enter step S14;
Wherein, this step can judge in the preset range of Non-contact Media Reader whether have non-contact IC card by sensor, because the power consumption of sensor is not an order of magnitude fully for the power consumption of processor, so judge by sensor and can save electric energy greatly.In addition, type of sensor preferably adopts the capacitive sensing device, certainly, is not limited to capacitive transducer for type of sensor, also can adopt optical sensor, infrared sensor etc.
Step S13, the dormant state of described processor is converted to duty, and by the non-contact IC card process chip that described processor is controlled described Non-contact Media Reader the data in the described non-contact IC card is read;
Wherein, when in sensor is judged the preset range of Non-contact Media Reader, having non-contact IC card, then need processor to enter duty, so the dormant state of processor is converted to duty.And, also need processor to control the non-contact IC card process chip of Non-contact Media Reader, so that the non-contact IC card process chip reads the data in the non-contact IC card.
Step S14, duty is converted to dormant state.
Wherein, when non-contact IC card leaves the preset range of Non-contact Media Reader, need so the duty of processor is converted to dormant state.
In the embodiment shown in fig. 1, as long as when in the preset range of Non-contact Media Reader, not having non-contact IC card, the processor of Non-contact Media Reader just is in dormant state so, when only in the preset range of Non-contact Media Reader, having non-contact IC card, the processor of Non-contact Media Reader is just in running order, reduced the working time of processor so greatly, processor always is not in dormant state when having non-contact IC card, so reduce the Non-contact Media Reader electric quantity consumption, energy savings.Therefore, scheme provided by the invention has and cuts down the consumption of energy and advantage such as energy savings.
See also shown in Figure 2ly, shown in Figure 2 is a kind of Non-contact Media Reader 1, comprises processor 12, the sensor 11 and the non-contact IC card process chip 13 that are connected with described processor 12 respectively; Wherein, described sensor 11 is for whether having non-contact IC card 2 in the preset range of judging described Non-contact Media Reader 1; Described processor 12, be used for when described Non-contact Media Reader 1 powers up startup the duty of described processor 12 is converted to dormant state, and judge when having non-contact IC card 2 in the preset range at described sensor 11, then dormant state is converted to duty, the data of controlling in 13 pairs of described non-contact IC cards 2 of described non-contact IC card process chip read; Judge when not having non-contact IC card 2 in the preset range at described sensor 11, then duty is converted to dormant state.
At Fig. 1 and the described embodiment of Fig. 2, come the solution of the present invention is described below by concrete application scenarios: suppose that Non-contact Media Reader provided by the invention is applied on the gate control system, need swipe the card at Non-contact Media Reader when wherein, the employee of company goes to work or comes off duty.After the keeper powered up startup with Non-contact Media Reader, the duty of the processor of Non-contact Media Reader will be converted to dormant state automatically so, and remains dormant state.When employee's working of company is checked card, the sensor of Non-contact Media Reader will detect and have non-contact IC card so, at this moment, sensor will send the signal that dormant state is converted to duty to processor, the processor state of then resuming work again then, the non-contact IC card process chip that processor can be controlled described Non-contact Media Reader reads the data in the described non-contact IC card, reads and finishes, and illustrates that this employee checks card successfully.When the employee left the preset range of Non-contact Media Reader with non-contact IC card, processor returned to dormant state automatically from duty again.As everyone knows, processor is being in dormant state following time, its power consumption is very low, so processor is only just in running order in needs, and from the daylong time, the time of checking card all concentrates on the working in morning and come off duty evening, so except two periods of checking card, processor all is in dormant state, and therefore scheme provided by the invention has significantly reduced the energy consumption of processor, thereby has saved electric power energy.
Need to prove that Fig. 1 is the preferred embodiment that the present invention introduces to embodiment shown in Figure 2, those skilled in the art can design more embodiment on this basis fully, therefore do not give unnecessary details herein.
Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments herein.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
