Embodiment Construction

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] like figure 1 As shown, it includes a 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. Below the surface layer 3 of the target body, there are one light-emitting circuit and two receiving circuits; the light-emitting circuit 5 generates near-infrared light, injects it into the transmitting fiber, and then shoots toward the surface layer 3 of the target body; when there is ice, the near-infrared light is An optical phenomenon occurs in the ice, and then a part of the light is reflected back into the receiving fiber 8 through the transparent material. When detected by the light conversion circuit, the l...

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. Road icing is mainly caused by water or snow on the road and low temperature. At this stage, only relying on the driver's observation to determine the ice type can easily lead to the occurrence of traffic accidents. At present, the detection of icing is mainly used in aircraft, and many icing sensors used for icing detection do not have the ability to identify ice types, such as conductivity type, differential pressure type, radiation type and piezoelectric diaphragm type. ice sensor. In addition, there are very few icing sensors that can identify ice types, such as the international patent "ICE DETECTION APPARATUS AND METHOD" with the patent number of WO 2004 / 110865 A1, although it has the ability to identify three t...
