Application development of encoder in the field of industrial automation control

With the continuous development of industrial control, the demand for selecting encoders is getting higher and higher. In industrial control, rotary encoders are generally mainly used in devices such as proximity switches and photoelectric switches. The rotary encoder has the characteristics of high reliability, high environmental adaptability, and excellent control performance.

The development of industrialization, from mechanization to automation, has now developed in intelligence, softening, informationization and safe production. Encoders are essential sensors for this development. From the perspective of the application of the encoder, it can be used as an angle sensor, indirectly as a length sensor, and as a speed sensor. In industrial control, incremental encoders focus on speed control applications, and are widely used in variable frequency motors, servo motors, synchronous elevators, etc., incremental rotary encoders are used as high-speed, high-precision speed control applications.

First, the elevator industry

Encoders are mainly used for the position control of the car and the speed control of the elevator in the elevator industry. According to data recently released by the National Bureau of Statistics, 2018 has increased by about 10% compared with 2017's overall data in China's elevator industry. Now, with the decline in the real estate boom and the increase in the overall combination of the elevator industry, the elevator industry is showing a low-speed development trend. In the next 1 to 2 years, we are looking forward to the encoder or growth trend in the elevator industry.

Second, the encoder is in the servo control area

The servo market experienced a blowout explosive growth during the one-and-a-half year period from 2017 to 2018. After June 2018, there has been a split. Some industries and companies have experienced a cliff-like sharp decline. Of course, some industries have made gains in the servo field. Steady growth. It can be seen from the application of the encoder that in some market segments of the servo industry, the sunrise and sunset are in a process of differentiation.

Third, the encoder is in the machine tool industry

According to statistics released by the China Machine Tool Association in January 2019, the overall revenue and profit of China's machine tools in 2018 were slightly better than in 2017. For machine tool companies, most of the main customer base comes from the automotive industry. In 2018, China's automobile industry showed a downward trend, and the stagnation of the automobile industry is not good news for the development of the machine tool industry. Taking into account the country's investment policy to supplement shortcomings, there are also policies that tilt toward the machine tool part when investing in fixed assets as a whole. It is expected that the machine tool industry in 2019 will be the same as 2018.

Fourth, the encoder is in the field of robotics

From the data of the first three quarters of 2018, the output value of the world's robotics industry reached 20 billion U.S. dollars, of which the Chinese market was 5.5 billion U.S. dollars. In fact, from the point of view of the global robot development speed, it has increased by 13.6%, and from the overall point of view of China's robot development, it has increased by 18%. The growth of China's robotics industry is due to the in-depth exploration of the robot market in the servo field caused by the inclination of national policies. It can be seen that the robotics industry has room for growth in the next 1-2 years.

Fifth, the encoder is in the military industry, subdivided fields

Military supplies and subdivisions also grew steadily in 2018. In large-scale industries, domestic encoders alone had double-digit growth in 2017. Although servos declined in the second half of 2018, they were still growing.

In the process of technological development and industry 4.0, not only equipment but also a large number of sensors and software are required to obtain real data in real time. As the sensor at the end of the entire machine, the encoder is responsible for capturing real data and performing the role of the brain. . The encoder plays a very important role in it.
