Embodiment approach 1
[0047] Include the following steps:
[0048] Step 1, initialize the system: the microcontroller sets the time when the circuit enters the lock, and sets the time when the circuit is unlocked;
[0049] Step 2, the single-chip microcomputer detects the signal from the key switch output: the single-chip microcomputer in the locked state receives 5 switching signals from the key switch within 1.5 seconds, and the single-chip microcomputer unlocks. Since both locking and unlocking are to turn on the key switch 5 times within 1.5 seconds, if the user makes the switch turn on once or twice due to misoperation, the microcontroller will not unlock. And because the time is short, there will be no such situation that the key switch is turned on 5 times within 1.5 seconds due to misoperation, so this setting is safer.
[0050] After unlocking, the single-chip microcomputer receives the signal from the key switch again, and the circuit is connected to the single-chip microcomputer to outp...
Embodiment approach 2
[0064] This implementation mode is completely the same as the above implementation mode except that the unlocking circuit lock and the locking circuit are different from the above one implementation mode.
[0065] The single-chip microcomputer detects the signal from the key switch output: the single-chip microcomputer in the locked state receives the first continuous signal from the key switch output in 4 seconds, and the single-chip microcomputer is unlocked. After unlocking, the single-chip microcomputer receives the signal from the key switch again, and the circuit Turn on the microcontroller to output electrical signals to the transistor. The transistor amplifies the signal from the microcontroller and outputs it to the load. If the MCU receives the second continuous signal from the key switch output in 8 seconds, the MCU enters the locked state and has no output signal; that is, press and hold the key switch for 8 seconds to continuously output the signal of the switch c...
