The figure illustrates a circuit involving dark tomb electric locks, specifically the fti: al: 4046B and XOR gate as the primary control mechanism. It emits pulses and utilizes silicon for successive pulse generation. The circuit operates with a normal button in an NC (Normally Closed) position, where specific components interact to manage the electric current. When the button is pressed, it initiates a sequence that involves a voltage-controlled oscillator (VCO) and an XOR gate. After a brief delay, the VCO begins to function, generating a continuous pulse that influences the operation of a stepping motor. The circuit is designed to control the speed of the motor based on the button's interaction, with specific timing and voltage characteristics dictating its performance. Upon releasing the button, the VCO ceases operation, and the system resets.

The circuit described employs a combination of the 4046B phase-locked loop (PLL) and an XOR gate to create a control mechanism for dark tomb electric locks. The 4046B serves as a voltage-controlled oscillator (VCO), generating a frequency output that can be adjusted based on the voltage applied. The XOR gate functions as a logic control element, determining the output based on the state of the input signals.

In the typical operation mode, when the button is in its normal NC position, it allows current to flow through the circuit. Upon pressing the button, a brief delay of approximately 0.5 seconds occurs before the VCO begins to oscillate. This delay is crucial for establishing a stable output frequency. The output from the VCO is then fed into the XOR gate, which produces a one-shot pulse that can be utilized to trigger further actions in the circuit.

The continuous pulse output from the VCO can be modulated to control the speed of a stepping motor. The frequency of the output pulse can be adjusted by varying the voltage input to the VCO, allowing for precise control over the motor's operation. The circuit is designed to handle a range of operational conditions, ensuring that the stepping motor can be accurately positioned based on the pulse frequency.

If the button is released within 0.5 seconds, the system is designed to stop the VCO and reset the output. This feature allows for precise control of the motor's position, as the pulse width and frequency can be finely tuned to achieve the desired operational speed. The design also incorporates components such as resistors and capacitors to stabilize the circuit and manage the timing of the VCO output.

Overall, this circuit configuration provides a robust solution for controlling electric locks with a focus on precision and reliability in motor operation. The integration of the 4046B and XOR gate facilitates a versatile control system that can be adapted for various applications requiring accurate timing and pulse generation.The figure shows that dark tomb electric locks, fti: al: 4046B and XOR f] as the main control circuit, called S emitted pulses and silicon successive pulses built 4 Shaanxi.
