The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
This method is used the non-contact measurement means, and the material that falls into surveyed area is detected, and judges whether this position load-transfer device longitudinal tear phenomenon occurs.
Promptly surveyed area is provided with a leakage material detecting device below load-transfer device, whether leak the material detecting device launches wireless signal and detects and have material to fall in surveyed area, when load-transfer device has been torn material and has been leaked down to surveyed area from tearing port, the material that leaks down is caught by leakage material wireless signal that detecting device is launched, and then judges conveyer band discerption.
Wireless signal adopts ultrasonic signal, and its frequency limit is from 20KHz to 100MHz.Ultrasonic signal runs into material and blocks, signal reflex, signal attenuation can take place, utilize this specific character, can detect signal reflection phenomenon at homonymy with sender unit, with the another side with respect to material of sender unit, can detect the signal attenuation phenomenon, utilize this two kinds of phenomenons, can judge material and leak down, and then can judge longitudinal tear has taken place.
Wireless signal adopts optical signal, and its range of wavelength is from 0.2 micron to 1000 microns.Optical signal has covered infrared ray, visible light and ultraviolet ray, blocks when optical signal runs into material, can signal reflex take place, signal is blocked.Utilize this specific character, can detect signal reflection phenomenon at homonymy with sender unit, with the another side with respect to material of sender unit, can detect the signal phenomenon that is blocked, utilize this two kinds of phenomenons, can judge material and leak down, and then can judge longitudinal tear has taken place.
Wireless signal adopts electromagnetic wave signal, and its range of wavelength is from 0.02 micron to 10000 microns.Electromagnetic wave signal runs into material and blocks, and signal reflex, signal attenuation can take place.Utilize this specific character, can detect signal reflection phenomenon at homonymy with sender unit, with the another side with respect to material of sender unit, can detect the signal attenuation phenomenon, utilize this two kinds of phenomenons, can judge material and leak down, and then can judge longitudinal tear has taken place.
Referring to Fig. 1 and Fig. 2
Leak the material detecting device and in surveyed area, be provided with a transmitting terminal 1 and a receiving end 5, transmitting terminal 1 emission wireless signal 4, receiving end 5 receives wireless signal 4, load-transfer device 3 is not torn under the normal circumstances, the wireless signal 4 of transmitting terminal 1 emission is receiving without any launching the blocking of obstacle under and being received end 5, judges that load-transfer device 3 nothings tear this moment.
When having material 2 to fall, wireless signal 4 propagation paths are blocked, and receiving end 5 does not receive wireless signal 4, and then judgement load-transfer device 3 is torn.
