As shown in Figure 1, identify that card comprises tank circuit II, rectifying and voltage-stabilizing device, charge management circuit, rechargeable battery, CPU, identify card ID projector, also comprise the CPU potentiostat for CPU offer stabilized voltage. Wherein, tank circuit II is formed by an air core coil L2 is in parallel with an electric capacity C2, and L2 and C2 is set as responding to the specific frequency electromagnetic signal from wireless charger. Rectifying and voltage-stabilizing device provides stable constant direct current charging voltage for rechargeable battery, and charge management circuit is connected between rectifying and voltage-stabilizing device and rechargeable battery in order to control the break-make of charging circuit. CPU by the working order of conventional sense circuit monitoring rectifying and voltage-stabilizing device and charge management circuit, and and can be shown to user by corresponding pilot lamp. Identifying in card and also comprise tank circuit I and limiting circuit, tank circuit I can be responded to low-frequency excitation signal and produce alternating current, and the electric current that tank circuit I produces is delivered to CPU by limiting circuit, and such CPU can monitor the working order of tank circuit I. Tank circuit I is formed by an air core coil L1 is in parallel with an electric capacity C1, L1 and C1 is set as sensing the low frequency signal f2 launched from well head card reader, the current limit that tank circuit I is produced by limiting circuit is in a certain fixing scope, to prevent infringement when tank circuit 2 outward current is excessive, CPU produced. CPU also can be connected with corresponding LED pilot lamp, and to indicate the using state identifying card, as, in charging, charging is full, electricity is not enough, in normal operation, launches ID code etc.
For making card volume little, there is stopping property, and battery long service life, battery need not be changed again, rechargeable battery should preferably adopt Large Copacity portable cell, such as poly-lithium battery.
At ordinary times, CPU controls ID projector with a certain specific frequency f 1, by certain transmitting cycle, constantly sends this card ID code, and operating distance is distance transmission, and the light on and off that also can control relay indicating light when launching are to indicate the working order identifying card.
CPU can monitor low frequency signal F according to certain sense cycle, when the tank circuit I identified in card senses specific low frequency signal F, CPU monitors after tank circuit I produces alternating current, namely control identifies that card ID projector sends ID code with radio frequency f2, and the light on and off that also can control relay indicating light when launching are to indicate the working order identifying card. When identifying that card sends f1 code and f2 code, the light on and off state of relay indicating light preferably has obvious difference so that the instruction of LED is more meticulous.
This project have employed unique wireless charging scheme. As long as identification card being placed on 2��3 hours, charger surface, battery charging can be completed. Card has charging and is full of instruction, and automatically transfers trickle charge state after filling to. Card charging once can work more than three months. More than poly-lithium battery in theory chargeable 300 circulations, (capability retention more than 80%) thus substantially prolongs the work-ing life identifying card. When identifying that card is placed on wireless charger, tank circuit II senses the electromagnetism signal from wireless charger and produces alternating current, and this electric current is transported to rectifying and voltage-stabilizing device and carries out rectification and voltage stabilizing, generates constant DC voltage. In this example, the voltage that rectifying and voltage-stabilizing device exports is 5V. Battery is carried out constant-current constant-voltage charging by charge management circuit by this voltage, during charging, charge management circuit is conducting state, the voltage of rechargeable battery is monitored by charge management circuit, when cell voltage rises to battery specified completely electricity voltage, charge management circuit automatic cut-out, stops battery being carried out normal charge, transfers trickle charge state to. In this example, the specified full electricity voltage of battery is 4.2V.
Whether whether CPU according to the charging state of battery in the cycle periodic monitoring card set in advance, such as, enter charging state, be full of, and monitor cell voltage at any time. If finding to identify that card enters charging state, when namely CPU monitors rectifying and voltage-stabilizing device generation stabilized voltage, CPU control identifies that card ID projector stops sending the ID code of this card immediately, and controls the light on and off of corresponding LED pilot lamp. When battery is full of, CPU, by the light on and off of the corresponding LED pilot lamp of control, represents that charging stops. When identifying that card leaves charger, CPU monitors rectifying and voltage-stabilizing device and no longer produces charging voltage, identifies card and auto-returned normal operation state, and CPU controls ID projector and restarts to launch ID code, and the bright corresponding relay indicating light in reference mark.
Below for identifying the working control flow process of card: setting sense cycle and transmitting cycle in CPU in advance, in this example, sense cycle is 100ms, and the transmitting cycle is 2s. Identify and card is also provided with three status indicator lamps, be respectively red light, green light and amber light. Wherein, during the normal bright expression of red light is charged; Green light normal bright time represent that battery is full; Amber light flicker represents that identification battery card electricity is not enough, it is necessary to charging; Green light flicker represents that ID code launched by identification card, and wherein flicker represents that identification card is launched to well head card reader after receiving low-frequency excitation continuously, and single flicker expression identifies that the locking phase sends ID code to downhole transmitter. The integrated control method identifying card as shown in Figure 2, comprises the following steps:
(1) when 100ms timing then, CPU detect charging voltage, otherwise execution step (6);
(2) when CPU detects charging voltage, perform step (3), otherwise perform step (4);
(3) when battery underfill, CPU controls red light Chang Liang; When battery is full of, CPU controls green light Chang Liang;
(4) when CPU detects actuation signal F, perform step (5), otherwise perform step (6);
(5) CPU control ID projector frequency f 2 sends ID code, and control green light dodges 3 times;
(6) when 2s timing then, CPU detect charging voltage, otherwise execution step (1);
(7) when CPU detects charging voltage, perform step (8), otherwise perform step (9);
(8) when battery underfill, CPU controls red light Chang Liang; When battery is full of, CPU controls green light Chang Liang;
(9) CPU control ID projector frequency f 1 sends ID code, and controls green light and dodge 1 time;
(10) CPU detect cell voltage lower than normal operation voltage such as 3.5V time, the control every 10s of amber light dodges once, identifies that to point out user card needs charging.
In above-mentioned control method, namely the every 100ms of CPU detects low-frequency excitation signal F, and every 2s frequency f 2 sends ID code, all carries out charging voltage detection every time, and carry out battery electric power detection after every 2s sends ID code before detection signal and transmission ID code.
