Wgs-l030 Laser speed and length measuring device

Overview: Laser Doppler Velocity WGS-L030, developed by Wuhan CenterRise M&C Engineering Co., Ltd., is a measuring instrument for measuring the speed and length of online, high-temperature and high-speed moving objects using high-precision laser Doppler velocity sensor. sensor. It is used to measure the speed and length of hot strips in rolling mills. The WGS-L030 laser Doppler velocity measurement system is mainly composed of two parts: a hardware system and a software system. The hardware system includes a set of laser Doppler speed sensors to measure the relative speed of hot rolled strips and sensors. The sensor arithmetic unit calculates the length of the steel plate passing through the sensor according to the measurement data of the laser Doppler velocity sensors and transmits it to the main system. The software in the main system calculates the speed and length of the hot-rolled strip according to the data of the arithmetic device, and displays the corresponding data and change curves. The alarm will be triggered according to the deviation threshold set by the software system or manually, the hardware equipment is installed on the loop frame or L-frame above the measurement strip on site. The software system is mainly used to analyze and process the strip measurement data collected by the hardware system, and displays the hot-rolled strip speed and length data analyzed by the software on the display panel, and also sends control and alarm instructions to the hardware system. Measuring principle of the system: The working principle of Laser Doppler velocimetry is shown in the figure below. A velocity sensor is an instrument that uses the laser Doppler effect to measure the speed of a fluid or solid. It usually consists of five parts: laser, incident optical unit, receiving optical unit, Doppler signal and data processor. The main advantages of laser Doppler velocity measurement are non-contact measurement, linear characteristics, high spatial resolution and fast dynamic response. The Laser Doppler Velocity Sensor uses the LDV system of advanced optoelectronics and microprocessor technology, which makes it easier to measure liquid or solid in 2D and 3D. The laser probe's tracer particle uses the Doppler frequency shift of light scattered by moving particles to obtain velocity information. Since this is a laser measurement, Doppler frequency has a linear relationship with speed and has nothing to do with temperature and pressure. This is a device with the highest speed measurement accuracy in the world. Composite system layout: Fixed length cutting diagram of laser speed and length measuring instrument uses the system structure shown in the figure to realize a set of laser Doppler speed and length measuring system. The hardware system's sensors are a group of laser Doppler velocity sensors mounted on one side or above the slab being measured to test for vertical diffuse reflection. The hardware system remotely transmits the collected data to the host system. The measured velocity data is combined with the measured time to calculate the measured slab length and calibrate the shear. This method produces highly accurate and stable measurement data. Parameters: Slab width: ≥100mm Slab length: >2000mm Slab thickness: 1～300mm. Plate speed:
