The characteristics of absolute encoder_absolute encoder application

The principle of absolute encoder

There are many optical channel engraved lines on the optical code disc of absolute value encoder, and each engraved line is arranged in 2 lines, 4 lines, 8 lines, and 16 lines in sequence. In this way, at each position of the encoder, by reading each engraved line The opening and darkening of the line obtain a set of unique binary codes (Gray codes) from the zero power of 2 to the n-1 power of 2, which is called an n-bit absolute encoder.

The absolute encoder uses a rotating disc with a number of transparent and opaque windows, and collects the intermittent light beam passing through the rotating disc through a light receiver, converts the optical pulse signal into an electrical pulse signal, and then processes it by an electronic output circuit. And send out the electrical pulse signal.

Features of absolute encoder

1. No need to remember, no need to find reference point, with power-off memory function

2. Multiple communication protocols

3. Fast start speed, precise motion control of multiple axes

4. Anti-interference characteristics and corrosion resistance

5. High precision, high stability, high reliability

The shell material of the absolute value encoder has many advantages. The absolute value encoder has a better performance in strength control and corrosion resistance. Excellent material performance is the foundation of the equipment environment adaptability. For users In other words, when purchasing the corresponding absolute encoder, you can first select the appropriate machinery and equipment from the material of the equipment. Of course, there will be more outstanding performance in data processing speed and many other performance indicators. Excellent workmanship and good performance guarantee the performance of the absolute encoder.

Absolute encoder application

1. Application in solar water heater

Utilizing the displacement change of the absolute value encoder enables the solar energy to follow the sun's rays and change step by step during use, ensuring that the solar panel can absorb solar energy in a large area;

2. Application in construction machinery

It is mainly used in cranes, elevators and cranes and other equipment, using the precision of the absolute value encoder to measure the angle, displacement, and change value of the machine during operation;

3. Application in the medical industry

The use in the medical industry is mainly in the use of medical machinery and equipment, such as automatic control of operating tables, measuring the angle change value through the installation of an absolute encoder, and transmitting the measured value to the sensor, thereby automatically controlling the operation The control handle on the bed realizes control;

4. Application in vehicles and other vehicles

The absolute encoder is in the car. The use of the above is also known as the four-wheel positioning encoder. In its use, it is mainly to test each wheel of the car to understand whether the car wheel is in a normal state, whether the correction point is correct, etc., so that it can be sensitive to the car wheel Detailed understanding of parameters such as performance and wide temperature;

5. Application on elevators and other lifting equipment

Absolute encoders are widely used in the startup of lifting equipment. The elevator is one of the typical cases. During the elevator lifting process, rigorous time calculation and control are required. The function of the encoder is to measure the electronic equipment in the elevator. The displacement value and angle value are fed back through these data, so that the staff can understand the working status of the elevator;
