Number, and issue 433MHz radio-frequency information；And cylinder side can send infrared signal and receive 433MHz information, to verify key side
Information whether match.Key side and cylinder side specific works are as follows:
1, key side: on the key, design has arbitrary single-chip microcontroller (such as MSP430G2001 single-chip microcontroller), designs simultaneously
There are infrared receiving module circuit and the bluetooth transmitting line of 433MHZ, is equipped on software protocol and receives infrared excitation code, bluetooth
Send the mode of synchronous head, ID (identity code) data and transmission end code etc., the bluetooth that ID is reliably passed through into 433MHz
Technology is sent in cylinder side.
2, cylinder side: on lock core, design has arbitrary single-chip microcontroller, inside has Flash ROM or EEPROM that can save journey
The a plurality of key id information of sequence and setting, under program control, MCU send infrared excitation code to infrared receiver on the key
Pipe, the 433MHz transmit circuit of single-chip microcontroller initiation key sends ID data on the key after matching, and lock core receives the 433MHz of key
The ID data of radio-frequency transmissions judge to control motor if identical with the presence or absence of ID identical with key in lock core storage inside
Lock tongue buckle is opened, achievees the purpose that opening lock master, if the mechanical tartar of key not pair or ID is not right, does not fail to open lock
Core.
For the power supply for reducing cylinder side, the configuration switch in lock core, while power supply holding circuit is realized in circuit.Reach
Only be inserted into mechanical key, power circuit works, and does not consume electric energy usually, extend battery life, meanwhile, key side it is infrared
Reception pipe is also to control it by single-chip microcontroller to start and stop, and usually power consumption is very low.
Specific workflow is as follows:
Single-chip microcontroller on the key carries out short pulse power supply to infrared receiving module while reading whether infrared receiving module has
Signal input, key only has single-chip microcontroller and infrared receiving tube U5 to work when usually inputting without correct infrared signal, and power consumption
It is very low.When key is inserted into lock core, the switch (P4 in such as Fig. 9) in lock core can be pressed, GND and PGND conducting, single-chip microcontroller U2
Work is started power up, the GND-CON in Fig. 6 is connected to the I/O port of U2 (STM8S105 single-chip microcontroller), and single-chip microcontroller can control GND-
The level realization of CON controls the power supply of lock core single-chip microcontroller, and PGND is connected to the cathode of battery, and VCC is connected to battery
Anode, and the power supply end of lock core single-chip microcontroller is attached to VCC and GND respectively, when P4 key does not press namely key
It is not inserted into and when system cut-off state, then this pin for being connected to single-chip I/O mouth of GND-CON is floating state, the collection of N1
Electrode and emitter are not turned on, so that P1 collector and emitter disconnects, so that N3 collector and emitter disconnects, therefore battery
Line PGND and the GND ground wire of single-chip microcontroller power supply are not turned on, therefore do not become galvanic circle, system power dissipation very little, when key is inserted into
Lock core, then the P4 key in Fig. 9 is pressed, and GND and PGND directly connect together, and SCM system powers on, and passes through program
Control single chip computer GND-CON pin is high level, then N1 collector and emitter is connected, thus P1 and N3 collector and emitter
Conducting, that is, GND and PGND realize conducting by single-chip microcontroller control GND-CON pin, SCM system can keep be
System is powered, meanwhile, when key is extracted, it is low level that lock core single-chip microcontroller, which controls GND-CON pin, then GND and PGND pin is disconnected
It opens, realizing only insertion key, then lock core single-chip microcontroller U2 is started power up and worked, and single-chip microcontroller has the function of control system power on/off
Energy.Key is inserted into lock core, and one key switch holding circuit GND-CON of single-chip microcontroller U2 (using STM8S105 single-chip microcontroller) control system draws
Foot is that high level realizes system electrification, powers on rear 3 lock core end infrared transmitting circuit of control figure transmitting infrared excitation code, wherein
F38KHZ is connected to 11 pins of single-chip microcontroller U2 and provides carrier wave, TX-HW to infrared transmitting tube LED1 (such as: TSAL6200 model)
12 mouthfuls for being connected to single-chip microcontroller U2 send data to LED1.Infrared receiving circuit on the key is as shown in Figure 10, U3 monolithic machine examination
Measured infrared excitation code then begin through control U4 realize Figure 13 this 433MHz radio frequency transmitter circuitry module (such as: H34B-
433) send key ID to Fig. 4 on U1 less radio-frequency receiving module circuit (such as: H3V4F), the U2 of Fig. 2 is connect by the U1 of Fig. 4
Receive after ID compared with the ID in U2 storage inside, illustrate if consistent key be it is matched, U2 controls driving circuit Fig. 5
(this is classical H bridge motor-drive circuit, and bridge end is connected to motor positive and negative anodes, and P-M+ and P-M- are connected to the I/O port of U2,
IMotor is connected to the AD analog-to-digital conversion interface measurement motor rotation blockage electric current of U2, and U2 controls the two pins of P-M+ and P-M- and realizes
Control to motor, R14 are a small resistance, and the partial pressure size of the electric current that it is flowed through above above it shows the work of motor
Whether normal, then electric current is big for stall, and the voltage on R14 is also just big, and the A D interface that IMotor is connected to U2 collects its voltage just
Know motor whether stall, therefore stall judgement can be carried out), can be with if the tartar of mechanical part is also verified at this time
