1. Safety information and warnings

Safety

The system control unit contains hazardous voltages (110V AC or 230V AC mains depending on market). Disconnect or isolate from the mains supply before opening the door of the control unit. Power can be disconnected from the IEC plug on the underside of the control unit. The control unit must be earthed.

The sensor head contains a visible laser diode of up to 35mW. The side of the sensor head has a warning label indicating the wavelength and intensity of the lasers in the sensor head.

The system is a Class 3B device, according to EN60825: 1992. It is dangerous to look directly into the laser beam. Ensure that suitable precautions are taken so that direct viewing of the beam or viewing of reflections from mirror-like surfaces is not possible.

The system is provided with fail-safe indicators on the sensor head and on the operator pendant. A keyswitch is also provided on the control unit to allow the laser to be disabled.

The laser should be disabled before any maintenance is performed on the sensor head or welding torch when it may be possible to view the laser directly.

The sensor head and control unit contain no user serviceable parts. No work should be undertaken on these items except by or under the direct guidance of appropriately trained personnel.

To ensure safe and reliable operation of the system, all operators must be made aware of the correct operation and safety procedures for the system. The safety procedures should be based on the above information, installation specific issues concerning the use of the system and any

local safety requirements.

Warnings

Do not weld with the sensor unless a spatter shield and a protective window have been fitted correctly.

Please ensure that clean, dry, oil free air or gas is supplied to the air connectors on the top of the sensor body. Oil or water in the air supply will obscure the sensor view and stop it working correctly. It may also damage the sensor optics at the front of the sensor head. The welding shield gas or other bottled gas may be used, or alternatively air from a compressor can be used as long as it is clean, dry and oil free. A flow rate of approximately 5-8 litres per minute is normally required. When you place your hand underneath the sensor, you should feel a gentle breeze on the back of your hand. The flow should not be so high as to disturb the shield gas, while being sufficient to keep most of the smoke and spatter off the protective window.

It is important that the sensor is provided with adequate cooling. The air supply above provides some cooling, but where this is not sufficient, additional cooling to the mounting plate for the sensor head can be used. This may be connected to a supply of cool water or to provide additional air cooling.

The sensor head can also be cooled by providing chilled air from a Vortex type cooler unit. This cooled air can be supplied to both the air connector (at a flow rate of 5-8 litres per minute) and also to the ‘water cooled’ mounting plate by feeding the chilled air into either one of the ‘water connectors’ and allowing it to escape out of the other connector. The flow rate to the mounting plate should not exceed 12

litres/minute.

The user of the equipment must ensure that the cooling does not cause condensation to form on the windows or optics at the front of the sensor head, as this can stop the sensor from performing correctly. Although the sensor head is sealed against dust and being splashed by water, condensation must not be allowed to remain on the sensor head or pool around it for extended periods.

You must turn the system off when replacing any parts, including the External GIO or the sensor head. If you do not do this, the system may fail to operate correctly.

2. Introduction

4. How the sensor works

The sensor head contains an advanced camera, and a laser. The laser shines a red stripe onto the surface under the sensor. The camera views this stripe and from the shape of the stripe is able to see the shape (profile) of the seam. In front of the camera is a special filter that allows the light from the lasers to pass, but keeps out nearly all other light, such as the light from the welding arc.

The sensor must be mounted in front of the welding torch in a position such that it can see the seam clearly. The distance from the sensor body to the workpiece should be correct for the type of sensor being used. When the welding torch is correctly positioned over the seam, the seam should be close to the middle of the laser stripe. This is so that the camera can clearly see the laser stripe and the seam within it. When the sensor is mounted correctly, the sensor picture of the seam will show the picture near the middle of the sensor view when the welding torch is at a good welding position.

Sensor Head Laser stripe on the surface Camera view

The sensor head is available with a range of different views depending on the application. The SLS V sensors are the standard range. The SLS H range are specially designed to be able to fit inside small diameter tubes and pipes (down to 6”/150mm ID).

The picture from the camera is then processed by the electronics in the sensor head. It looks in the picture and decides where the stripe is in the picture. The software then uses the settings from the seam type to divide the stripe into lines that form the seam. From the position of the lines that make the seam, the system can then decide where the position of the seam is. This is then converted from a measurement in the picture into a measurement in mm of the seam position under the sensor. This conversion is performed using the ‘calibration data’ that is stored in each sensor head.

When the system is tracking, it uses the welding speed and the distance between the sensor and the welding torch to calculate a delay time. It compensates for this delay time when using the measurements of the seam position to drive the slides to keep the welding torch positioned over the seam.

5. Operation

This section describes the operation of the Laser Probe. For details of how to install and set-up the Laser Probe system, please refer to the Laser Probe Installation and Support manual.

The Laser Probe system is operated from the Operator Pendant, and also by the switches on the Control Unit.

5.1. Control Unit Switches

The control unit has the following switches.

?Power on/off switch

?Laser Enable keyswitch

?Mode keyswitch

5.1.1. On/Off Switch

Turning the power switch on the front of the control unit clockwise turns on the system. When power is on the touch screen display (GIO) will start to turn on. The system performs a range of self tests, and if it doesn't find any problems will turn on the LED in the start button on the operator pendant to show that the system is ready to be started. If the system does detect a problem it will turn on the red status LED. You can then use the display on the GIO or the Smart Laser Tools program to determine the cause of the error. Note that the GIO may take longer than the rest of the system to power on - the rest of the system can be used as soon as the green pendant start button illuminates, even if the GIO is still starting up.

Turn the power switch anti-clockwise to turn off the system. Note that all settings that have been entered are stored in the Smart Laser Probe system, so the power can be turned off and on without the need to set-up the system again. When not in use the equipment can be left turned on or turned off as convenient.

5.1.2. Laser Enable Keyswitch

For safety reasons, it is possible to disable the lasers in the sensor head. This is done by turning the Laser Enable keyswitch to the anticlockwise (OFF) position. The key can only be removed in the OFF position. To operate the system it is necessary to place the key in the switch and turn it to its clockwise (ON) position. It is necessary for the lasers to be enabled before it is possible to make any measurements with the system. If you try to use the system with the lasers disabled, an error message will be displayed on the GIO and the red status LED on the Operator Pendant will illuminate.

When performing maintenance on the sensor head or welding torch, or when untrained personnel are working by the sensor head, the Laser Enable key must be turned to the OFF position. The Laser Enable keyswitch must also be turned to the OFF position if the sensor head is to be moved to a position where it is possible to look directly into the end of the sensor.

Please refer to the safety regulations in force in your area for appropriate safety information.

5.1.3. Mode Switch Keyswitch

The mode switch controls the operating mode for the equipment. It is a two-position keyswitch, and in normal use it should be in its anticlockwise position, RUN. The key can be removed when it is in the RUN position to ensure that the system set-up cannot be modified.

Certain aspects of the set-up that has been made for your system can be adjusted from the menus that are displayed when this keyswitch is turned to the SETUP position. Please only attempt this if you are familiar with the set-up of the Smart Laser Probe system and are authorised to do so. To control access to these modes, it is possible to remove the key when in the RUN position.

5.2. Operator Pendant - Description

The Operator Pendant is used to operate the Smart Laser Probe system.

The Operator Pendant has the following LED lamps and controls.

?Four bicolour illuminated JOG buttons (left, right, up and down)

?Illuminated START button

?Illuminated STOP button

?LASER button and laser warning lamp

?Illuminated bicolour STATUS button

?Illuminated SEAM button

?Illuminated OFFSET button

Some operator functions described below can be turned off when the system is installed if they are not required. This is done during the installation of the system, and it is noted in the description below. Some operations such as starting the sensor searching and tracking, and seam number selection can be performed by a connection to a PLC. These are also described below, but for details of how this is set-up, please refer to the Smart Laser Probe installation manual.

The boxes in the following description show what you will see on the display on the Operator Pendant.

5.3. Operator Pendant - in Standby – Operations

This section describes the operations that you can perform on the Operator Pendant, when the sensor is not searching or tracking a seam. This mode is called Standby.

5.3.1. Jogging the slides

The 4 JOG buttons can be used to jog the slides. When jogging the slides, the slide will move slowly at first, gradually getting faster over a few seconds until the maximum jog speed is reached. This allows fine control of the jog position to be achieved while still being able to jog larger distances at a higher speed. The green LEDs in the joy switches are lit when it is possible to jog the slides. Note that if the system is under automatic control, e.g. searching for or tracking along the seam, the greed LEDs in the jog switches will turn off, to show that you are not able to jog the slides.

The slides will stop when they reach the limit switch, and will not move any more in the direction of that limit switch. Note that when in Standby and jogging, reaching a limit switch does not cause an error to be reported. However, when a limit switch is active the red LED in the jog switches is illuminated, and the end of the slide icon on the GIO turns red to indicate which limit is active.

Selecting the seam number

If necessary, the Smart Laser Probe system can be set up to search for and track several different seams. The different settings that the system needs for the different seams are stored as separate seam numbers.

Different seam numbers can be selected by holding down the SEAM button, and using the JOG up to increase the seam number or JOG down to decrease the seam number. The green led in the jog up or down button will flash briefly if the seam number changed. Seam numbers always start from 1. Only seam numbers where the seam have been created will be selected - any seam number that has not been created will be skipped. It is also possible to select the seam number from the GIO, from the 'seam' tab.

It is possible to disable changing seam number from the pendant. It is also possible to select the seam number from a PLC via digital signals. Whichever way it is selected, the active seam number is shown on the GIO display.

5.3.2. Turning the sensor lasers (measurement) on and off

Pressing the LASER button will turn the lasers on. When the lasers are on, the Smart Laser Probe system will continuously attempt to measure the position of the seam, relative to the middle of the field of view of the sensor. Pressing the LASER button again will turn the lasers off. You can also turn the lasers and measurements on and off from the GIO. When the laser is on, the STATUS LED will turn green when the sensor is able to measure the position of the seam, and turns off if the seam is not visible.

5.3.3. Automatically adjusting the picture brightness

The SLS sensor head will normally automatically adjust the picture brightness depending on the current surface below the sensor. Adjustment of the picture brightness is not normally required.

激光传感器的工作原理及其应用

激光传感器由激光器、激光检测器和测量电路组成。激光传感器是新型测量仪表,它的优点是能实现无接触远距离测量,速度快,精度高,量程大,抗光、电干扰能力强等。激光传感器工作时,先由激光发射二极管对准目标发射激光脉冲。经目标反射后激光向各方向散射。部分散射光返回到传感器接收器,被光学系统接收后成像到雪崩光电二极管上。雪崩光电二极管是一种内部具有放大功能的光学传感器,因此它能检测极其微弱的光信号,并将其转化为相应的电信号。常见的是激光测距传感器,它通过记录并处理从光脉冲发出到返回被接收所经历的时间,即可测定目标距离。激光传感器的应用 利用激光的高方向性、高单色性和高亮度等特点可实现无接触远距离测量。激光传感器常用于长度、距离、振动、速度、方位等物理量的测量,还可用于探伤和大气污染物的监测等。 激光测长 精密测量长度是精密机械制造工业和光学加工工业的关键技术之一。现代长度计量多是利用光波的干涉现象来进行的,其精度主要取决于光的单色性的好坏。激光是最理想的光源,它比以往最好的单色光源(氪-86灯)还纯10万倍。因此激光测长的量程大、精度高。 激光测距 它的原理与无线电雷达相同,将激光对准目标发射出去后,测量它的往返时间,再乘以光速即得到往返距离。由于激光具有高方向性、高单色性和高功率等优点,这些对于测远距离、判定目标方位、提高接收系统的信噪比、保证测量精度等都是很关键的,因此激光测距仪日益受到重视。在激光测距仪基础上发展起来的激光雷达不仅能测距,而且还可以测目标方位、运运速度和加速度等,已成功地用于人造卫星的测距和跟踪。 激光测振 它基于多普勒原理测量物体的振动速度。多普勒原理是指:若波源或接收波的观察者相对于传播波的媒质而运动,那么观察者所测到的频率不仅取决于波源发出的振动频率而且还取决于波源或观察者的运动速度的大小和方向。所测频率与波源的频率之差称为多普勒频

前言 尊敬的客户: 衷心的感谢您选择了深圳市南方测控技术有限公司的激光测距传感器! 为了让您更好的使用本激光测距传感器与防止意外事故的发生,请您在使用本激光测距传感器前仔细的阅读本说明书。 本说明书的版权归属深圳市南方测控技术有限公司所有,如在不影响本激光测距传感器整体性能的前提下所作的修改或更新,恕不另行通知。

激光测距传感器系统说明 术语解释 激光测距:利用激光对目标的距离进行准确测定。激光测距一般采用两种方式来测量距离:脉冲法和相位法。 脉冲激光测距:基于激光脉冲反射时差法原理,测距仪器发射出的激光经被测量目标反射后,激光束被测距仪器接收,测距仪器记录激光往返的时间。光速和往返时间的乘积的一半,就是测距仪器和被测量物体之间的距离。 激光测距传感器:为工业测量之产品,采用工业标准设计、生产和检测,可在线24小时连续实施测量,有的可以多台组网测试。 激光安全等级:国际上对激光有统一的分类,激光器分为四类(Class1、Class2、Class3、Class4)。Class1激光器对人是安全的,Class2激光器对人有较轻的伤害,Class3以上的激光器对人有严重伤害,使用时需特别注意,避免对人眼直射。

随着现代工业生产向高速化、自动化方向的发展,生产过程中长期以来由人眼起主导作用的颜色识别工作将越来越多地被相应的颜色传感器所替代。例如:图书馆使用颜色区分对文献进行分类,能够极大地提高排架管理和统计等工作;在包装行业,产生包装利用不同的颜色和装潢来表示其不同的性质或用途。目前的颜色传感器通常是在独立的光电二极管上覆盖经过修正的红、绿、蓝滤波片,然后对输出信号进行相应的处理,才能将颜色信号识别出来;有的将两者集合起来,但是输出模拟信号,需要一个A/D电路进行采集,对该信号进一步处理,才能进行识别,增加了电路的复杂性,并且存在较大的识别误差,影响了识别的效果。TAOS(Texas Advanced Optoelectronic Solutions)公司最新推出的颜色传感器TCS230,不仅能够实现颜色的识别与检测,与以前的颜色传感器相比,还具有许多优良的新特性。 1 .TCS230芯片的结构框图与特点: TCS230是TAOS公司推出的可编程彩色光到频率的转换器,它把可配置的硅光电二极管与电流频率转换器集成在一个单一的CMOS电路上,同时在单一芯片上集成了红绿蓝(RGB)三种滤光器,是业界第一个有数字兼容接口的RGB彩色传感器,TCS230的输出信号是数字量,可以驱动标准的TTL或CMOS逻辑输入,因此可直接与微处理器或其他逻辑电路相连接,由于输出的是数字量,并且能够实现每个彩色信道10位以上的转换精度,因而不再需要A/D转换电路,使电路变得更简单,图1是TCS230的引脚和功能框图。 图1中,TCS230采用8引脚的SOIC表面贴装式封装,在单一芯片上集成有64个光电二极管,这些二极管分为四种类型,其16个光电二极管带有红色滤波器;16个光电二极管带有绿色滤波器;16个光电二极管带有蓝色滤波器,其余16个不带有任何滤波器,可以透过全部的光信息,这些光电二极管在芯片内是交叉排列的,能够最大限度地减少入射光辐射的不均匀性,从而增加颜色识别的精确度;另一方面,相同颜色的16个光电二极管是并联连接的,均匀分布在二极管阵列中,可以消除颜色的位置误差。工作时,通过两个可编程的引脚来动态选择所需要的滤波器,该传感器的典型输出频率范围从2Hz-500kHz,用户还可以通过两个可编程引脚来选择100%、20%或2%的输出比例因子,或电源关断模式。输出比例因子使传感器的输出能够适应不同的测量范围,提高了它的适应能力。例如,当使用低速的频率计数器时,就可以选择小的定标值,使TCS230的输出频率和计数器相匹配。 从图1可知:当入射光投射到TCS230上时,通过光电二极管控制引脚S2、S3的不同组合,可以选择不同的滤波器;经过电流到频率转换器后输出不同频率的方波(占空比是50%),不同的颜色和光强对应不同频率的方波;还可以通过输出定标控制引脚S0、S1,选择不同的输出比例因子,对输出频率范围进行调整,以适应不同的需求。

A SENSOR FOR LASER ULTRASONIC MEASUREMENT OF ELASTIC PROPERTIES DURING MANUFACTURE P. Ridgway 1, R. Russo 1, E. Lafond 2, T. Jackson 2, X. Zhang 2 Lawrence Berkeley National Laboratory, Berkeley, CA, USA; 2 Institute of Paper Science and Technology at Georgia Tech, Atlanta, GA, USA Abstract: An automated sensor has been developed for use in paper manufacturing and for demonstration on a full scale paper machine during commercial operation. This laser ultrasonic sensor provides non-contact and on-line measurement of the elastic properties of paper and paperboard. It was tested on a pilot web handler at web speeds up to 12.7 m/s. Measurements of flexural rigidity and out-of-plane shear rigidity were made by fitting the frequency dependence of the phase velocity of A o Lamb waves mode to a model equation. Ultrasonic waves were generated in the paper with a pulsed Nd:YAG laser and detected with a Mach-Zehnder interferometer coupled with a scanning mirror/timing system to compensate for paper motion. On-line measurements agreed very well with off-line laboratory measurements. Introduction In Laser Ultrasonics (LU), also known as laser-based ultrasonics, acoustic waves can be generated with a pulsed laser in a material to determine one or more of its physical properties. These acoustic waves are also often monitored with a laser-based detector, usually a form of interferometer, without physical contact to the sample (1). In this work, plate waves (also called Lamb waves) (2) are detected several millimeters from the generation point as they propagate along the sheet. A diagram of this system is shown in Figure 1. Laser ultrasonics has been applied in recent years to measurement of mechanical properties of paper in the laboratory (3,4). Further laboratory demonstrations of LU on moving paper demonstrated the possibility for routine measurement of these properties during manufacture, and for feedback control of the papermaking process based on these measurements (5,6). Further developments in signal processing and the results of a miniaturized and industrialized scanning LU sensor on moving paper are discussed in this paper. Figure 1.
