Embodiment Construction

[0019] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0020] Such as figure 1 As shown, it includes the matching target body 2 integrated with the road surface 1, and the target body surface layer 3 of the matching target body 2 is a light-transmitting material, and the selection of the light-transmitting material is consistent with the icing performance of the road surface material. Under the surface layer 3 of the target body, it includes one light-emitting circuit and two receiving circuits; the light-emitting circuit 5 generates near-infrared light, injects it into the emitting optical fiber, and then shoots to the surface layer 3 of the target body; when there is ice, the near-infrared light An optical phenomenon occurs in the ice, and then a part of the light will be reflected back into the receiving optical fiber 8 through the transparent material. When the light conversion circuit detects i...

Abstract

The invention discloses an icing information detection method, which comprises the following steps: forming a 3*1 input layer matrix X0 by collected information; obtaining the weighted sum A0 of input layers and a weight by a weight W1 between the input layers and hidden layers; obtaining hidden layer output X1 by a hidden layer excitation function; obtaining a weighted sum A1 on an output layer by a weight W2 between the hidden layers and the output layer; and obtaining the output y of the output layer by the hidden layer function. Network training is carried out by an experiment sample, ice thickness information is obtained by carrying out the network training and inputting new data, and an ice type is obtained by a curve between result description time and ice thickness.

Description

technical field [0001] The invention relates to the detection of icing process, in particular to a method for detecting icing information. Background technique [0002] Generally, the types of road icing can be divided into frost ice, clear ice and mixed ice. The hazards of different ices to road travel safety and the requirements for road anti-icing and deicing are different. Road icing is mainly caused by the accumulation of water or snow on the road and the low temperature. At this stage, only relying on the driver's observation to judge the ice type can easily lead to traffic accidents. At present, the detection of icing is mainly used on aircraft, and many icing sensors used for icing detection do not have the ability to identify ice types, such as conductivity, differential pressure, radiation and piezoelectric diaphragm junctions. ice sensor. In addition, there are few icing sensors that can identify ice types, such as the international patent "ICE DETECTION APPARAT...
