An article lets you know about embedded sensors

The embedded controller, formerly known as the spectral confocal controller, is a smart sensor that can be used for measurement without having to match a PC. Can save resources to a great extent, save time and cost.

 

 

one Five components and introduction of embedded controller


The intelligent embedded controller of Liyi Technology is composed of arm embedded core, FPGA high-speed processing unit, optical fiber probe, sensor and PC software.


Arm-side embedded kernel: the heart and center of the product, it is responsible for all data processing and scheduling. It is responsible for collecting high-speed data from FPGA, processing it by algorithm, and transmitting the measurement data to host computer through network. A device that converts measurement data into analog output to which it is connected.


FPGA high-speed processing unit: a real-time high-speed acquisition and processing module, responsible for high-speed acquisition and control of sensor output image data, and through various algorithms to calculate the peak value. The spectral data and the calculated crest data are sent to the arm end. Control and collect encoder data at the same time, and send the data to the arm end.


The parameters of the acquisition chip are set by receiving the FPGA control signal. According to the set parameters of the acquisition probe reflected back spectral data, the image data is transmitted to the FPGA end.


Optical fiber probe: mainly receives the white light emitted by the luminizer, and reflects it back by focusing on the measured object through the principle of optical fiber, prism and spectral confocal. The light is decomposed by the spectrometer and is emitted on the sensor according to the wavelength to form spectral picture data.


PC side software: mainly responsible for setting ARM-related parameters through the network, remotely upgrading the arm side program, user rights management, soft data, real-time display and data collection.


Second, product features:


2.1 The same controller can be adapted to multiple probes, and the controller can be enlarged to adapt to various measurement scenarios.


2.2 Fast sensor measurement speed and high accuracy. Using advanced arm core and high-speed FPGA acquisition and processing unit, it can meet various application scenarios in speed and accuracy. The acquisition and output speed can reach more than 10K, and the accuracy can also reach 0.1um.


2.3 Small size, beautiful appearance, low power consumption.


2.4 Multiple input and output interfaces. Support network, serial port, USB, analog, GPIO signal input and output and other connectors.


2.5 Convenient calculation function, not only can calculate the maximum, minimum and average value, but also can carry out a scan of the multi-point average height and object outline. The user only needs to power on the controller and connect the optical fiber probe to select the measurement scheme for testing through the display screen.


After listening to the introduction of the small edition of the vertical instrument, I believe that you must have a general understanding of our spectral confocal intelligent embedded sensor. Shenzhen Liyi Technology Co., Ltd. has been focusing on spectral confocal displacement sensors and their application supporting products since its establishment in 2014, and has solved the problems of high-precision measurement for hundreds of enterprises since its establishment.
