Programming of a new key is completed in three phases. The first is called when the serial number is read, in the programming phase and the second is called when the programming button is pressed. This procedure is shown on figure 4.įor the programming mode there exists two subprograms: PROGT and PROGS, whose block diagrams show in figure 6. Basically, it's like registering the master key on the memory slot you would like to erase. To remove an already registered key, you follow an almost same procedure, using only the master key. Generally in any programming step, you can wait 5 second to exit programming mode. If you wait 5 seconds, programming mode will exit and nothing is going to register in memory. When you press the button the slot number increases by one and memory hasn't changed yet. If after step 7, you find out that you selected wrong slot number and you don't want to loose that key, press programming button or just wait 5 seconds. These steps can be revised as many times as you like. If you want to register more keys, then from step 9 you can go directly to step 5. The programming procedure to register a new key is displayed schematically on figure 3. After 5 seconds, the program exits from programming mode. If successfully registered the display stops blinking.ġ0.

Touch again the new key to confirm registration to memory.ĩ. The number on led display blinks, indicating ready to program.Ĩ. Push the programming button to select a different programming slot for your new key.ħ. That's the current selected slot in memory.ĥ. Led displays letter «P» that indicated you entered programming mode.Ĥ. To add a new key, the following steps should followed:Ģ. A connection diagram is show on figure 2. Led VD3 can be placed on the face of enclosure, to indicate proper powering of board. Part numbers HG1, SB1 and XS1 are used only in programming mode so can be placed inside the plastic enclosure. External components are connected on board with 2 or 3 pin connectors. In the place of AA batteries we could use a 12V sealed Lead - Acid battery. The most components are placed on the board, including the transformer. Overall board dimensions are 150х100х60mm. That can be done as the excess energy is consumed in heat, that can not harm batteries as its low. That's put the battery on a steady charge to compensate losses among time and no charge completion detection is needed. This current is equal to 0.025C (where C is the batteries capacity) and that's a very small current depending on total capacity. When the circuit is connected on main voltage the battery pack is charged via R10 with a current of 20mA. As power backup an array of 10 AA batteries is used (BT1-BT10). This electronic lock has it's own power supply on board, consisting of transformer T1, bridge rectifier VD9-VD12 and voltage regulator U4. If for a reason mcu freeze then U2 send it a reset pulse and work is resumed. On pin P3.1 mcu produces pulses when it works right. This chip have a counter and voltage test circuits inside it. For that reason we added ADM1232 (U2) that does the mcu reset pin control. But we need to ensure that the circuit will always work without supervision. This led is connected to the board using the same pin array XP2. This additional transistor is useful as it translates the mcu logic levels to 0V and 12V, capable to drive the solenoid.Ī led is used to indicate the state of the electronic lock, which is controlled from the same pin as the solenoid, using transistor TV1. Transistor VT3 is controlled from VT2, which reverses the logic state that's appears on P3.0, so on VT3 we have output 0V and 12V. Diode VD7 is added to protect MOSFET from voltage strikes due to solenoid inductance. Solenoid is controlled from a power MOSFET IRF540 (VT3). The solenoid that does the lock is connected on XT1 connector. The door OPEN button is connected on P3.2 through XP1 connector, using the same protection components as above.
This one is used for programming the keys. An additional iButton socket is connected parallel with the predefined at pins XS1. One pull-up resistor R4 is used as required from 1-wire protocol. The rest of components VD4, R3, VD5 andVD6 are used for protection of mcu ports. The external iButton socked is connected on port P3.3 via XP2 pin array. It is connected on P3.4 (SDA) and P3.5 (SCL) of U1.

Storage of iButtons serial numbers is done on a 24C02 EEPROM (U3). For the same reason a push-button labelled SB1 is connected on P.3.7. This led display will be used on the programming of additional keys. The port 1 (P1) of mcu is used to connect a 7-segment common anode led display. The circuit is build around an Atmel AT89C2051(U1) microcontroller.
