In 2022, the market size of China's floor sweeping robot industry reached 12.4 billion yuan, a year-on-year growth of 3.4%; floor sweeping robot penetration rate in high tier cities has been as high as 20%, but in the low tier cities is still insufficient, in the long run, China's floor sweeping robot market is still growth space, sinking the market will become the key to the development of the industry.
Adaptive sweeping technology era is coming
In 2015, the sweeping robot began to “sweeping and dragging robot” development, until now, the function of the market share has reached 92%. In recent years, various companies have further improved the recognition of the sweeping and dragging function, paying more attention to the development of adaptive sweeping technology, with material recognition module, to realize the development of different sweeping modes according to the different materials on the ground. In the future, this technology will realize the full coverage of “sweeping and mopping robots”, becoming a major point in the competitive landscape.
In the long run, a single functional intelligence to multi-functional integration to realize the 3.0 era of “total intelligence” is the key point of competition in the industry in the future.
Mainstream solutions for floor material identification
The material recognition technology of the sweeping robot is an important direction of intelligent development, and it is also the key to improve the sweeping effect and sweeping ability of the sweeping robot, usually using acoustic and optical two principles of recognition, but the optical principle of the sensor will be affected by the light and darkness of the detection results, on the contrary, the acoustic sensor is not affected by the light, and it is capable of detecting the carpet, flooring, and other different material categories in the darkness of the night, and its application advantages are more The application advantages are more obvious.
Due to the further sinking of the market, industry leaders to promote the overall price band downward, with high-performance ultrasonic material module sweeping robots are also gradually devolved 2000 yuan price. In the R & D "cost reduction" and product "iteration" double force, cost-effective, good recognition accuracy of ultrasonic material recognition module began to become the first choice of many manufacturers.
Principle of operation of ultrasonic material identification sensors
Ultrasonic material recognition technology based on the characteristics of ultrasound is not affected by light, color, the use of different materials on the sound wave absorption ability of different echo differences caused by the echo detection technology to distinguish between different materials, so as to accurately identify the carpet, the floor and other materials, to dominate the sweeping robot to start the correct cleaning mode purpose.
As a leader in the sensor technology industry, AUDIOWELL has launched a 300KHz high-frequency ultrasonic sensor based on piezoelectric ceramic technology, empowering the field of intelligent home appliances to optimize the performance of sweeping robots working on floors made of different materials.
High recognition accuracy
AUDIOWELL 300KHz ultrasonic sensor uses special coupling material to send ultrasonic waves to the air, and can accurately recognize the ground material, material detection distance up to 25-45mm, distance measurement accuracy up to millimeter level.
Strong recognition capability
The discriminatory output of AUDIOWELL 300KHz ultrasonic sensor can distinguish between tiles, wooden floors, carpets, plush mats, etc., basically covering common floor material types, helping the robot to adjust various cleaning programs in time and change the cleaning mode with the floor material.
Function reuse can be realized
The AUDIOWELL 300KHz ultrasonic sensor can realize dual-use of material recognition and cliff detection, preventing the robot from falling down the steps, and at the same time, it can optimize the internal structure of the robot and reduce the weight of the product to provide more room for improvement.
On the whole, ultrasonic 300KHz ultrasonic sensors have the advantages of low cost, high recognition accuracy, no interference and so on. Sweeping robots equipped with ultrasonic 300KHz ultrasonic sensor can support the adaptive sweeping technology of sweeping robots, further broadening the application scenarios.
