velocity

在机器人自动化技术中，旋转运动速度测量较多，而且直线运动速度也经常通过旋转速度间接测量。例如:测速发电机可以将旋转速度转变成电信号，就是一种速度传感器。测速机要求输出电压与转速间保持线性关系，并要求输出电压陡度大，时间及温度稳定性好。测速机一般可分为直流式和交流式两种。直流式测速机的励磁方式可分为他励式和永磁式两种，电枢结构有带槽的、空心的、盘式印刷电路等形式，其中带槽式zui为常用。

折叠激光测速

随着现今精密制造业的崛起和节省成本的需求，非接触测速传感器会慢慢取代接触式测速传感器。而现在市场上精度较、zui常用的非接触激光测速传感器就是ZLS-Px像差测速传感器。像差测速传感器有两个端口:一个发射端口，发出LED光源;一个是速拍照端口，实现CCD面积速成像对比，通过在极短时间内的两个时间的图像对比，分辨被测物体移动的距离，结合传感器内部的算法，实时输出被测物体的速度。如图所示，①LED光发射口，②摄像接收口，③、④接线端，⑤固定螺孔 。①LED光发射口对着被测物发射出激光，经反射到②摄像接收口，接收到信号后传给信号处理器，通过算法计算出它的速度。

特征

旋转式速度传感器按安装形式分为接触式和非接触式两类。

折叠接触式

接触式旋转式速度传感器与运动物体直接接触。当运动物体与旋转式速度传感器接触时，摩擦力带动传感器的滚轮转动。装在滚轮上的转动脉冲传感器，发送出一连串的脉冲。每个脉冲代表着一定的距离值，从而就能测出线速度。

接触式旋转速度传感器结构简单，使用方便。但是接触滚轮的直径是与运动物体始终接触着，滚轮的外周将磨损，从而影响滚轮的周长。而脉冲数对每个传感器又是固定的。影响传感器的测量精度。要提测量精度必须在二次仪表中增加补偿电路。另外接触式难免产生滑差，滑差的存在也将影响测量的正确性。速度传感器

折叠非接触式

非接触式旋转式速度传感器与运动物体无直接接触，非接触式测量原理很多，以下仅介绍两点，供参考。

[1].光电流速传感器

叶轮的叶片边缘贴有反射膜，流体流动时带动叶轮旋转，叶轮每转动一周光纤传输反光一次，产生一个电脉冲信号。可由检测到的脉冲数，计算出流速。

[2].光电风速传感器

风带动风速计旋转，经齿轮传动后带动凸轮成比例旋转。光纤被凸轮轮盘遮断形成一串光脉冲，经光电管转换成定信号，经计算可检测出风速。

非接触式旋转速度传感器寿命长，无需增加补偿电路。但脉冲当量不是距离整数倍，因此速度运算相对比较速度传感器复杂。

旋转式速度传感器的性能可归纳如下:

(1).传感器的输出信号为脉冲信号，其稳定性比较好，不易受外部噪声干扰，对测量电路无特殊要求。

(2).结构比较简单，成本低，性能稳定可靠。功能齐全的微机芯片，使运算变换系数易于获得，故速度传感器应用极为普遍。

是一种将非电量（如速度、压力）的变化转变为电量变化的原件，根据转换的非电量不同可分为压力传感器、速度传感器、温度传感器等，是进行测量、控制仪器及设备的零件、附件。

XTD - SD - JCK9 speed sensor using circular tube type waterproof structure, has the advantages of waterproof, dustproof, prevent oil pollution can work reliably in harsh environment, is an advand speed sensor, especially suitable for industrial control and military project.
XTD - SD - JCK9 will speed sensor is a kind of non-electricity (such as speed, pressure) into power changes of the original, according to the transformation of non-electricity can be divided into different pressure sensor, speed sensor, temperature sensor, etc., are parts of measurement, control instruments and equipment and acssories. Speed sensor gsc6-sc, warranty year.
The working principle of
When the disk is rotating with the tape, the sensor's magnetic induction signal is input into the control circuit, which is counted by amplification and shaping. Compared with the preset number, it can judge the belt speed of the tape machine, namely: normal speed, skidding or speeding. At the same time, the execution circuit output corresponding switch signal.
When touch wheel rotates with adhesive tape machine running with motivation within the pulse, the pulse when rotating magnetic induction signal caused by the change of the input to the control circuit of speed sensor, after amplification circuit, comparn, plastic to count. Compared with the preset number, the speed of tape is judged and the corresponding switch signal is output. Not only: when the output is lower than the speed of sliding, the circuit output corresponding switch signal, so that the host machine stops. This switch can adjust the speed value.
velocity
In the robot automation technology, the rotation speed is measured more, and the linear motion speed is also measured indirectly through the rotation speed. For example, a speed generator can turn a rotational speed into an electrical signal, which is a speed sensor. The speed measuring machine requires a linear relationship between the output voltage and the speed, and requires the output voltage to be large, and the time and temperature stability is good. The speed measuring machine can be divided into direct flow and ac type. The excitation mode of dc speed measuring machine can be divided into two kinds: he excited type and permanent magnet type, the armature structure has the form of groove, hollow and disc type printing circuit, among which the groove type is the most commonly used.
Folding laser speed measurement.
With the rise of precision manufacturing and the need for cost savings, non-contact speed sensors will gradually repla contact speed sensors. Now, the high precision and most commonly used non-contact laser speed sensor is zls-px aberration speed sensor. The aberration speed sensor has two ports: a transmitting port, emitting LED light sour; Is a high speed photograph port, realize the high speed CCD area image contrast, through the two time in a very short time of image contrast, distinguish the distan of the moving object to be tested, combined with the algorithm of sensor inside, real-time output of the speed of the object to be tested. As shown in the figure, the LED light emitting port, the camera reiving port, the connection end, and the fixed screw hole. The LED light emitting port emits a laser to the measured object, and it is reflected to the camera reiving port. The signal is transmitted to the signal prossor after reiving the signal, and the speed is calculated by the algorithm.
Characteristics of the
The rotary speed sensor is divided into two types: contact and non-contact.
Folded contact.
The contact rotary speed sensor is in direct contact with the moving object. When the moving object is in contact with the rotary speed sensor, the friction fors the roller rotation of the sensor. A rotating pulse sensor mounted on a roller sends a series of pulses. Each pulse represents a rtain distan, so that the linear velocity can be measured.
The contact rotation speed sensor is simple in structure and easy to use. However, the diameter of the contact roller is always in contact with the moving object, and the outer circumferen of the roller will wear out, thus affecting the circumferen of the roller. The pulse number is fixed for each sensor. The measurement accuracy of the sensor is affected. To improve the measurement accuracy, the compensation circuit must be added in the secondary instrument. In addition, it is hard to avoid slip differen, and the existen of slip differen will affect the accuracy of measurement. Speed sensor
Folded contactless.
The non-contact rotary speed sensor has no direct contact with the moving object, and the non-contact measurement principle is very much. The following are only two points for referen.
[1]. Photoelectric velocity sensor.
The blade edge of the impeller is attached to the reflective film, and the impeller is rotated during the flow of the fluid, and the impeller turns a reflection on every week, producing an electrical impulse signal. The flow rate can be calculated by the number of pulses detected.
[2]. Photoelectric wind speed sensor.
The wind drives the anemometer to rotate, and the CAM is rotated in proportion after the gear drive. A series of optical pulses are formed by blocking the optical fiber, which is converted into a fixed signal by the photoelectric tube, and the wind speed can be detected by calculation.
The non-contact rotating speed sensor has long life and no need to increase the compensation circuit. But the pulse equivalent is not an integer multiple, so the speed operation is more complex than the speed sensor.
The performan of rotary speed sensor can be summarized as follows:
(1). The output signal of the sensor is the pulse signal, and its stability is relatively good. It is not easy to be interfered by external noise, and there is no special requirement for the measuring circuit.
(2) simple structure, low cost and reliable performan. Fully functional microcomputer chip makes operation transform coefficient easy to obtain, so speed sensor application is very common.
