Technical field
It is related to sensor field, and in particular to contactless water speed measurement sensor, automation equipment, city river network are intelligently supervised
Examining system.
Technical background
Existing sensor, with high costs, cost very high to requirement on machining accuracy is very high, complex structure, sensor is,
The important component of the intake environmental information of robot, if sensor it is expensive be the popularization of present robot technology threshold,
The development in intelligent epoch is hindered, the development of great rejuvenation of the Chinese nation cause is hindered, the sensor pair of various low costs is researched and developed
All it is highly desirable in the development of robot technology, intelligent city.
More sensitive sensor is more accurate, the small environmental change of easier sensing, and sensor is more sensitive more is conducive to setting
Standby high speed reaction, the sensor price of existing high sensitive is very expensive.
The content of the invention
The present invention relates to contactless water speed measurement sensor, automation equipment, city river network intelligent monitor system, Neng Gouti
For a kind of Sensor Design new approaches.
1st, contactless water speed measurement sensor, it is characterised in that:Including laser (S1), two photoreceptors, reflective mirrors
(S5), transparent pipeline (S2);Reflective mirror (S5) can reflect more than 80% light;Laser (S1), reflective mirror (S5) set respectively
Put in the both sides of transparent pipeline (S2);Flow velocity for measuring the transparent fluid (S3) for flowing through transparent pipeline (S2);
The laser that laser (S1) sends initially passes through the transparent fluid (S3) of transparent pipeline (S2), then via to reflective mirror
(S5) reflect, be irradiated on photoreceptor after free flow body (S3) is passed through again;The same hot spot of the laser that laser (S1) sends
Fall on two photoreceptors simultaneously;It is relatively fixed between laser (S1), two photoreceptors, transparent pipelines (S2) motionless.
2nd, contactless water speed measurement sensor, it is characterised in that:The type of two photoreceptors is identical.
3rd, contactless water speed measurement sensor, it is characterised in that:The laser that light device (S1) sends and transparent pipeline (S2)
