General Requirements of Industrial Automation Systems to Sensors


With the automatic driving, industrial 4.0, wisdom of the wave of medical, automotive, industrial, medical three emerging market sensor applications to grow rapidly. Especially in automatic control applications and industrial equipment, it is the eyes and ears.Such as temperature and humidity sensors that can monitor and adjust the operation of air conditioning, infrared sensors that can detect hot spots, CMOS sensors that detect images, and so on. In addition, due to the different attributes and needs of each manufacturing industry, the use of sensors, customization will be an inevitable trend.


Compared to the stability of the sensor needs in consumer electronics, automotive, industrial, medical three emerging market emerging sensing market, involving a wide range of cross-domain knowledge, in recent years become components and applications, equipment manufacturers, Important goals. Unlike consumer electronics, which focuses on inertial components, the three emerging markets have a wide range of sensing areas, and the need for cross-sectoral cooperation is quite high, leading to the development of solutions more differentiated, with irreplaceable.

And the automotive market is a single application, the industrial market applications more broken and fragmented, different manufacturing industry attributes, different solutions.

Although in different industrial properties, but most of the plant contains the machine processing, assembly, testing, logistics, four processes, and each process, there are different sensing technology needs.

For example, in the machining process, the most popular topic is device diagnostics. Among them, the acceleration sensor can help determine whether there is abnormal vibration; and temperature sensor can be used to determine whether the abnormal temperature, or the machine becomes overheated condition.


In the assembly process, the more obvious application of the sensor system is the robot arm. In the past, the robot arm is only used to move things, in order to be able to assemble, you must have the acceleration sensor to do the crawl, and gyroscope to do the rotation function, even if you want to lock the robot screws, but also torque sensors.


In the detection process, optical sensors are now widely used in semiconductors, panels, circuit board industry, can help find the human eye can not find the packaging product defects. The newer case is wearing glasses into the factory, the device combines the three sensors, microphones, acceleration sensors, 3D vision, will be able to detect the machine through the process of thermal variation, to determine whether parts of the symptoms of failure .

Not only that, there are manufacturers are discussing intelligent in future inspection process. Previously, the inspection staff must go to the room for meter reading, and then the relevant check. Now if you can do through the glasses to do the actual situation integration, labor costs can be reduced by many, including image sensing technology is very important. In the logistics section, such as AGV trucks, infrared or magnetometers can be used to automatically detect the direction.
