Smart meters can control the speed. This mainly relies on its built-in PWM (Pulse Width Modulation) technology and PID (Proportional Integral Derivative) control.
PWM technology is an analog control technique that achieves motor control by continuously modulating pulse signals with the same period but different duty cycles. Smart meters use PWM technology to output specific PWM waveforms to motors, thereby controlling the output power and speed of the motors.
PID control, on the other hand, is a more complex control strategy that calculates an error value by comparing and calculating the actual output value, expected functional value, and compensation signal through the controller. Then, through the control process of proportionality, integration, and differentiation, the error is minimized to achieve stable operation of the controlled object. In the application of smart meter speed control, when the set speed is reached, the smart meter will calculate the error based on the feedback signal and fine tune the motor through PWM technology to maintain a stable speed.
In addition to PWM technology and PID control, some smart meters also adopt more advanced speed regulation mechanisms. For example, a speed control smart meter uses a set control mechanism and components such as sliding blocks, stress springs, tension springs, etc., imitating the principle of variable resistors, to change the current through the control wire, thereby achieving precise adjustment and feedback control of motor speed.
Overall, smart meters can achieve precise control of motor speed through the use of PWM technology, PID control, and advanced speed regulation mechanisms. This not only helps to improve the service life and efficiency of the motor, but also greatly reduces the consumption of electrical energy, achieving the goal of energy conservation and emission reduction.
