Wheelchairs play an increasingly important role in the lives of people with disabilities and the elderly. Therefore, the choice of wheelchair sensor should also be given the appropriate attention.
There are many ranging sensors, a wave range sensor ultrasonic sensor is cheap, can be used to detect objects farther away. Ultrasound detection technology is widely used, and it has been successfully used in ranging, sounding, flaw detection, medical detection, etc., and its typical application is ultrasonic ranging technology, and it is not an optical device, is not affected by color changes .
Photoelectric switch diffuse and infrared sensors is a set of transmitter and receiver in one sensor, but the detection distance is usually 1 meter below the detection distance is short; CCD uses passive ranging, the detection of the light around the target can To get the location information of the target, the cost is not too high, but when in the light of night and other low-light environment, we must adopt the active distance measurement, then need extra light.When using the general light source, the power consumption is very large When the laser is used, the laser sensor can detect a large distance, but the cost is increased because more sensors need to be installed on the wheelchair to meet the testing requirements.
The characteristics of the use of wheelchairs group determines the range of activities of electric wheelchairs are not too large, the speed is not too high, the body sway, bumpy is not very intense.
