Description
Technical field
The preparation method of a kind of digital rubble flow sensor of the present invention belongs to the test technique automatic field; Particularly be a kind ofly to be applicable to the rivers and creeks, mountain valley Freshets roar down from the mountains under the situation; In the very first time that rubble flow produces; Can directly detect rubble flow mud position and mud-rock flow movement state automatically, and quote the sensor of rubble flow assessment data and warning message.
Background technology
Few at the technology and the product that can adopt aspect the rubble flow detection early-warning and predicting both at home and abroad at present, detect demonstration pilot project and applicable cases both domestic and external according to national rubble flow, conclude to get up to be following several kinds:
1, video monitor: use round-the-clock picture pick-up device that rubble flow hidden danger district is monitored, though this method can be obtained field data, will lose efficacy night, leans on the supervision on duty of personnel's whole day equally, is difficult to realize the robotization detection alarm.
2, ultrasonic sensor: this series products mainly is suitable for the water-level detecting in broad waters.Instrument is installed in the top away from the water surface, transmits and receives ultrasound wave to the water surface, and measures electromagnetic reflection wavelength, cycle, measures the distance of the water surface apart from instrument, thereby confirms the plane water level.This type of production producer is all arranged at present both at home and abroad.Like Chinese patent " the self-adapting ultrasonic liquid level appearance " patent No. 932031064.It is the level transducer that national rubble flow detects the unique use of demonstration pilot project; The rubble flow in the gully can not form the plane that can supply detect; So he has lost reliability in the rubble flow position is detected, its data can not be as foundation, can only be as a reference.
3, infrasonic sensor: the sound of be mainly used in and monitor wind and rain, thunder and lightning, Freshets roar down from the mountains and rubble flow rolls, these sound noises are very strong, must rely on experienced professional to come analysis and distinguishing, are difficult to realize the robotization detection alarm.
4, wire break alarm: Japan develops for debris flow early-warning; He is lead of lira in the gully; If rubble flow thrusts lead and reports to the police at once, but wild animal, person poultry activity also possibly cause break alarm in the gully, more are difficult to judge the flow and the flow velocity of rubble flow.
Summary of the invention
The preparation method's of a kind of digital rubble flow sensor of the present invention purpose is:
