The on-line intelligent precise measurement system solution developed by our team is based on the core technologies such as advanced photoelectric measurement principles and unique program algorithms, and the core series products such as "laser eccentric wall thickness measuring instrument, laser diameter measuring instrument and length meter meter" are developed. It is the specific application of non-contact diameter measuring instruments and equipment in the production line, with fast measurement efficiency and high accuracy. Non contact measurement has no impact on the results, At the same time, the performance of high stability, high-speed transmission, anti shake and anti-interference is particularly outstanding. Compared with similar calipers, our laser calipers have integrated closed design, smaller volume and stronger adaptability to the environment. As the terminal sensor of the production system, it realizes precise docking and deep integration with the factory production equipment, and forms and provides integrated product technology solutions for customers.

1. Uniqueness of laser caliper and eccentric wall thickness measuring instrument

The laser caliper researched by our team has "no moving parts and no optical lens" inside, which is a completely different caliper method, reliable operation and safe use. Four high characteristics: high stability, high durability, high accuracy and high speed.

●High stability

The team adopts CCD array sensor and pulse laser light source, and the single exposure is only 0.2us, which can clearly identify the instantaneous change measurement objects such as the shaking workpiece and eliminate the shaking error. Therefore, even if there is wire jitter, high stability is maintained; The problem of large difference in measurement data caused by long single measurement time and wire jitter of similar instruments using laser scanning method is solved.

●High durability

There are no moving parts and optical lenses of the motor inside the equipment, and there is no measurement error caused by the slight change of the position of the optical parts due to the shaking and vibration. It can be used for a long time and can be used safely; It solves the problems of measuring deviation and regular professional maintenance caused by the aging of multi prism, motor moving parts and weak displacement of optical lens of the same kind of instrument using laser scanning method.

●High-precision

The principle of laser diffraction without motor is adopted, and the powerful signal processing system is used to realize high-precision measurement; To solve the problem that the same kind of instrument using laser scanning method has distortion of laser beam at different scanning positions due to the influence of inner multi prism and optical lens mounting accuracy, which affects the uniformity of scanning speed, affects the measurement accuracy, and the measured object has large measurement error at different spatial positions.

●High speed

With a new working algorithm, the scanning frequency can reach 2500 Hz without losing the measurement quality, and the fixed time of parameters is not less than 100 ns, so as to realize high-speed data acquisition, processing and transmission; It solves the problems of low sampling speed, inaccurate detection and poor measurement quality of similar instruments adopting laser scanning method, which can not meet the real-time interaction needs of smart factories.
