Light device) and neodymium glass laser etc., their structure is roughly the same, and feature is that small and firm, power is high.Neodymium glass laser is
The highest device of pulse output power at present has reached tens of megawatts.
The existing device based on infrared laser measurement charging ratio, usually carries out carriage area according to fixed-area
Equal part surveys the charging ratio of carriage body in such a way that infrared sensor is fixedly mounted on roof corresponding region center
Amount.But there are blind areas for the measurement of the device, error is larger, and measuring device does not have flexibility.
There are no the mature equipment for being loaded rate detection using laser sensor, jejune sides on the market at present
Case is measured by the way of ultrasonic wave, is not also commercialized.Ultrasonic measurement has the following deficiencies: that blind area is larger,
Greater than 20cm；Circuit design is complex, needs analog circuit, and needs complicated calibration.In addition, the cloth of ultrasonic measurement
Line is complex, using multi-strand cable, causes detection efficiency low.The shortcomings that infrared sensor ranging, has: precision is low, distance is close,
Directionality is poor.
