Washing automatic washing machine tech analytical techniques

Whether it is car owners or car-free family, certainly for automatic washing machines have heard, automatic washing machines in the field of car wash equipment, the occupying unshakable position, it is an efficient, environmental protection and other advantages by the majority car wash operator's favor, then the automobile market in the face of all kinds of vehicles, automatic washing machine is to identify how to do it?

Vehicle recognition technology is one of a variety of automatic car wash equipment key technology is fully automatic washing machine "eyes", without it, the world's washing machine will be in the dark, it will be difficult to guarantee the safety car wash. Car wash equipment to achieve safe, efficient washing, models must be equipped with advanced recognition technology, can accurately identify the various models. Otherwise, even the most advanced washing machine can only be impractical "vase."

Automatic washing machine into China has been 20 years of history, which also experienced a number of technical innovations, for every technological innovation are the previous generation of the inheritance and development. From the initial proximity sensor detects now not yet completely universal CCD (ie, the image sensor) technology, washing machine models recognition technology has undergone six updates.

The first generation of Ⅰ proximity sensor technology, which has been used in the early sixties and the seventies of the last century in Japan. It uses the proximity sensor to control brush top running track, only a rough outline of the vehicle identification, do not yet fully automatic identification models. This technology is "late" type of technology, that the sensor can only come into contact with the brush and began to run in the top of the body only after induction to models before adjustment brush running track, but can not judge in advance of the vehicle. Since the models rely mainly on information induction top brush, so if the bristles wear more serious, can cause inaccurate sensor models. Due to backward technology and there are many security problems, this technology in Japan will soon be eliminated. At present, some of the technology is still relatively weak small manufacturers adopt the technology.

The first Ⅱ generation of current sensor technology, the first generation of washing machines can already Ⅱ automatic car wash in the true sense, but there are many defects, such as: because it is relying on the current size to control the movement of the brush, so the voltage became unstable a major threat sensing precision. Chapter Ⅱ Generation washing machine has been used for a small number of sensors, these sensors can only judge the vehicle parked position, the total length of the vehicle, do not have the car appearance recognition. Now in the domestic market are mostly seen washing machine belonging Ⅱ generation of washing machines, though no longer need to fully manual operation, but the staff still have to be monitored at the side, to avoid accidents.

Generation Ⅲ ultrasonic sensor sensing technology, different from the previous two generations, the first Ⅲ generation automatic washing machine in car model identification technically inventive, by reflection of ultrasonic sensors to identify the vehicle. This technology enables the top of the brush before beginning work ahead geopositioning models and provides a good brush top running track, to recognize the foresight models aim to make up for the previous two generations of technology hindsight defects. On recognition accuracy, the first Ⅲ generation technology is much higher than the previous two generations. But it should be noted that the ultrasonic identification technology is still insufficient. An acoustic wave transceiver vulnerable to the external environment such as the interference of water vapor, dust, and other sources of electromagnetic ultrasonic easily penetrate the windshield cause can not be received, etc. caused by errors of judgment.

The first generation of Ⅳ, Ⅴ first generation model recognition technology, the first-generation model Ⅳ recognition technology uses optical sensors to identify techniques, using instead of the PLC CPU information processing, computing faster, more accurate identification. It can determine different parts of the body before photoelectric sensors in contact with the brush body height and location of various items of equipment, and has been calculated in advance predetermined trajectory good brush, truly safe, fast car wash. Chapter Ⅴ Ⅳ generation of the first generation technology is basically the same principle, it is grating photoelectric sensors or sensor technology, different from the two main points: first Ⅴ generation technology increases the number of sensors, more accurate positioning of the vehicle; the first generation of Ⅴ technology integrated use of a variety of means of identification, such as ultrasonic technology and integrated optoelectronic sensor technology applications. Chapter Ⅳ generation, Ⅴ-generation technology is currently part of the mainstream technology in Japan, most Japanese manufacturers of automatic washing machines are currently using the first-generation or second Ⅴ Ⅳ generation model recognition technology. Qingdao Sen MK cooperation with Japanese companies, for the Chinese market using the first-generation Ⅳ, Ⅴ first generation model recognition technology automatic washing machine, fill the gaps.

Chapter Ⅵ generation of CCD scanning detection technology, which made Japan's largest washing machine manufacturing enterprises MK Seiko Co., Ltd. successfully developed, not yet large-scale application.

Summary: China's automobile market cars more models varied, very complex. This requires automatic washing machine must be able to accurately identify a variety of complex models. Otherwise, the washing machine work will be a security risk. Thus, the majority of car wash operators in the selection and purchase of the washing machine, be sure to select the advanced technology to accurately identify the various models of automatic washing machines.
