Beneficial effect
This utility model card reader, on traditional card reader basis, increases and the power supply of card reading module is controlled so that it is the high card reading module of power consumption is without not powered operation when blocking, thus being substantially reduced power consumption.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the battery supply intelligent card reader of this utility model economize on electricity.
Detailed description of the invention
Develop simultaneously embodiment below in conjunction with accompanying drawing, this utility model is described in detail.
As it is shown in figure 1, this utility model provides the battery supply intelligent card reader of a kind of economize on electricity, including battery feed circuit, control and card testing circuit, card reading module, on and off switch, card reading antennas, infrared card detection head and alarm and indicating circuit; Wherein, the output of battery feed circuit is divided into two-way, on and off switch of leading up to is connected with card reading module, another road connects control and card testing circuit, card reading module connects card reading antennas, alarm and indicating circuit respectively and controls and card testing circuit, controls to be connected on and off switch and infrared card detection head respectively with card testing circuit;
Control and card testing circuit, sending according to the frequency set drives signal to detect head to infrared card, when receiving the electric impulse signal that infrared card detection head transmits, drives on and off switch to connect, when not receiving described electric impulse signal, control to enter low-power consumption mode with card testing circuit; When receiving the operation that card reading module transmits and completing signal, on and off switch is driven to disconnect; In the process that on and off switch is connected, if the output voltage of battery feed circuit being detected lower than, when setting threshold value, generating battery low-voltage signal and be transferred to card reading module;
Owing to controlling also there is power consumption with card testing circuit, the power consumption blocking detection in method conventional at present is about about 1/10th of card reader power consumption, it is typically in 15 to 20mA, this power consumption is still higher for battery powered equipment, the battery powered reader device of uncomfortable desired economize on electricity. The low power dissipation design that card Detection & Controling part is optimized by this utility model, by reducing the duty ratio of time of card detection working time, reduces total power consumption. Its concrete grammar is: using the simple processor of low-power consumption to operate under low-power consumption mode, regularly (about 1 second, i.e. setpoint frequency) is with whether the time detecting of 1ms has calorie requirement to read. When thus having reached without card, power supply power consumption only has 10uA level, significantly reduces the power consumption of power supply, to must power or need the smart card reader of low-power consumption to be provided with general significance of application by battery.
Infrared card detection head, launches infrared ray under driving signal function, and when there being card, the infrared ray reflected through card is received by infrared card detection head, produces electric impulse signal and is transferred to control and card testing circuit;
Battery feed circuit, when on and off switch is connected, powers for card reading module;
Card reading module, starts after the power-up, carries out Card Reader operation on the one hand, after Card Reader terminates, send operation and complete signal to controlling and card testing circuit, on the other hand, when Card Reader success, when institute's Card Reader unauthorized and when receiving battery low-voltage signal, drive alarm and indicating circuit;
Alarm and indicating circuit, provide corresponding prompting for cell voltage is low, the situation for unauthorized card of swiping the card successfully and swiped the card or warn.
Embodiment 1: the battery supply intelligent card reader of a kind of economize on electricity, including: battery feed circuit, control and card testing circuit, card reading module, on and off switch, card reading antennas, infrared card detection head and alarm and indicating circuit six are most.
Controlling and card testing circuit, be the circuit of a direct power supply in card reader, it is mainly made up of the CPU of low-power consumption and corresponding functional circuit. CPU works in low-power consumption mode, and the intervalometer regularly (about 1S, the frequency namely set) by working under low-power consumption drives infrared card detection hair to penetrate infrared ray. When having card, the infrared ray reflected through card is detected head reception generation electric pulse by infrared card, and this electric pulse wakes CPU, CPU up and drives on and off switch to connect the power supply of card reading module again; Card reading module starts rapidly after powering on, carry out Card Reader and associative operation, sending one by holding wire after having operated and complete signal to controlling and the CPU in card testing circuit, now CPU signals to the power supply of on and off switch disconnection card reading module immediately, subsequently into low-power consumption mode. After infrared card detection hair goes out infrared ray, during without card, CPU is still in low-power consumption mode.
Owing to this card reader is battery supply set, when the battery user that runs low is ignorant, based on such demand, this utility model design has battery low-voltage to detect, when there being people to swipe the card, when CPU detects low-voltage, inform that card reading module reminds user's voltage very low by cell voltage low signal line, it is necessary to change battery.
Alarm and indicating circuit mainly complete the man-machine interaction of close friend, such as the prompting of battery low-voltage, swipe the card successfully prompting, the warning etc. of unauthorized card.
This utility model is particularly suitable for the such project of electronic lock as brush smart card, its low-power consumption implementation is when less increase cost (about 10 yuan), and the smart card reader energy resource consumption of its realization is about 100,000/left and right of common card reader. For today of green energy resource revolution, beyond doubt there is great realistic meaning.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model. All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
