OCEASOFT sensors are the direct source of information for the entire machine vision system, mainly consisting of one or two image sensors, sometimes accompanied by light projectors and other auxiliary equipment. The main function of vision sensors is to acquire sufficient raw images for the machine vision system to process. Image sensors can use laser scanners, linear and area array CCD cameras or TV cameras, as well as newly emerging digital cameras.

OCEASOFT sensor classification

1) Linear displacement sensor: The function of a linear displacement sensor is to convert linear mechanical displacement into an electrical signal. To achieve this, a variable resistor slide rail is usually fixed at a stationary part of the sensor, and different resistance values are measured by the displacement of the wiper on the slide rail. The sensor slide rail is connected to a stable DC voltage, allowing a small current in microamperes to flow. The voltage between the wiper and the starting end is proportional to the length of the wiper's movement. Using the sensor as a voltage divider minimizes the requirement for the accuracy of the total resistance of the slide rail, because resistance changes caused by temperature variations do not affect the measurement result. 2) Angular displacement sensor: Angular displacement sensors are used for obstacle handling: using angle sensors to control your wheels can indirectly detect obstacles. The principle is very simple: if the motor angle sensor structure is operating but the gear does not turn, it indicates that your machine is blocked by an obstacle. This technology is very simple to use and highly effective; the only requirement is that the moving wheel must not slip on the floor (or slip too frequently), otherwise you will not be able to detect obstacles. An idler gear connected to the motor can avoid this problem; this wheel is not driven by the motor but is driven by the movement of the device: during the rotation of the drive wheel, if the idler wheel stops, it means you have hit an obstacle.

Precautions for using OCEASOFT sensors

1) If the electronic scale has been used for a long time, and the seal has aged, mixed with many impurities, and water mixtures and oil will seriously affect the contact resistance of the brush, causing the displayed numbers to jump continuously. At this point, it can be said that the electronic scale of the linear displacement sensor is damaged and needs to be replaced. 2) If the power supply capacity is too small, many issues may arise, so the power supply needs to have sufficient capacity. Insufficient capacity will cause the following situations: the movement of the melting glue will cause fluctuations in the display of the mold closing electronic scale, or the mold closing movement will cause fluctuations in the display of the injection molding electronic scale, resulting in large measurement errors. If the driving power of the solenoid valve is combined with the power supply of the linear displacement sensor, the above situations are more likely to occur. In severe cases, the voltage fluctuations can even be measured using the voltage range of a multimeter. If the situation is not caused by high-frequency interference, electrostatic interference, or poor neutrality, it may be due to insufficient power supply capacity. 3) Frequency modulation interference and electrostatic interference can both cause the displayed numbers of the linear displacement sensor's electronic scale to jump. The signal lines of the electronic scale must be separated from the high-voltage lines of the equipment in separate wire troughs. The electronic scale must mandatorily use a grounding bracket, and the casing of the electronic scale must have good contact with the ground. Signal lines must use shielded cables, and one end of the electrical box should be grounded to the shielded cable. If there is high-frequency interference, the voltage measurement using a multimeter usually shows normal, but the displayed numbers keep jumping; when electrostatic interference occurs, the situation is similar to high-frequency interference. To verify whether it is electrostatic interference, you can short-circuit the cover screw of the electronic scale to some metal parts on the machine using a power cord. As soon as it is short-circuited, the electrostatic interference will be eliminated immediately. However, it is difficult to eliminate high-frequency interference using the above method. Variable frequency drives and robotic arms often generate high-frequency interference, so you can try stopping the high-frequency drive or robotic arm to verify if it is high-frequency interference. 4) If the displayed data of the linear displacement sensor's electronic scale jumps regularly at a certain point during operation, or if there is no display data, this situation requires checking whether the insulation of the connection line is damaged and causing a regular short circuit to the machine casing. 5) The supply voltage must be stable. Industrial voltage needs to meet a stability of ±0.1[%]. For example, if the reference voltage is 10V, a fluctuation of ±0.01V is allowed. If not, it will cause significant display fluctuations. However, if the amplitude of the display fluctuation does not exceed the amplitude of the voltage fluctuation, the electronic scale is considered normal. 6) The alignment of the linear displacement sensor installation needs to be good, but parallelism allows an error of ±0.5mm, and angular error allows ±12°. However, if both parallelism and angular errors are too large, it will cause the displayed numbers to jump. In such cases, the parallelism and angle must be adjusted. 7) During the connection process, extra attention must be paid. The three wires of the electronic scale must not be connected incorrectly, and the power line and output line must not be swapped. If the above wires are connected incorrectly, it will result in significant linear errors, making control difficult and reducing control precision, while the display is prone to jumping phenomena.

OCEASOFT sensor applications

The geometric state parameters of train wheel flanges affect the speed and smoothness of train operation and are crucial for safe train operation. Traditional detection methods are relatively complex, usually involving specialized rulers with verniers for measurement, leading to significant errors due to manual data reading, and failing to achieve digital management of detection data. With the development of China's railway industry, train speeds are increasing, making precise and rapid inspection and digital management of train wheel flange state parameters increasingly important. The flange detector adopts modern sensor technology, microcontroller processing systems, and concise and stable mechanical structures, enabling convenient and precise continuous rapid measurement of geometric state parameters, achieving digitization of parameters such as flange height and rim thickness. Many sensors are used for detecting flange height, width, rim thickness, etc., with displacement sensors being the most concerned. There are many types of displacement sensors, and the current new sensor technology used for train wheel flange detection is called laser displacement sensors. Currently, the laser triangulation method is used for detecting train wheel flanges, offering high precision for short-distance measurements. The displacement sensor can be directly installed on the track for detection, or a laser reflective displacement sensor can be used as the measuring device. The laser sensor module scans the flange shape along a straight line direction while recording the entire flange data. Through a microprocessor, the entire flange contour curve can be obtained, thereby calculating flange width, flange height, 70mm wear amount, and wear area. Furthermore, the measured data can be uploaded to a computer to generate a database, utilizing advanced post-processing software for digital management of train wheel flanges. It can not only measure wheel pair wear on online operating trains but also sort wheel pairs for dimensional compliance on production lines. The development of transportation relies on detection technology, with instruments and sensors being the core of detection technology. In today's era of rapid power development, people not only hope to experience comfort and enjoyment but also desire safety. The development of sensor technology will bring more safety to people's lives and transportation, and the development of sensor technology in China will also drive the advancement of world-class technologies in transportation internationally.
