Description

TECHNICAL FIELD

[0001] The present application relates to the field of traffic safety, in particular to a pavement icing detection device and method applied to a road. BACKGROUND

[0002] The existing icing detection devices are mostly based on the principles of capacitive detection, optical fiber reflection signal detection, infrared laser emission signal detection, etc. The capacitive icing sensor can obtain relatively accurate data when measuring relatively pure measured objects, but the pollution elements in the natural environment will seriously affect the measurement data. For example, in the road traffic environment, the electrolyte content of the pavement water and the mud and other substances will seriously affect the measurement results of the dielectric constant. The optical fiber icing sensor is also seriously affected by the pavement pollution. The pollutants such as mud on the pavement will contaminate the emission and receiving end faces of the optical fiber, causing the infrared detection light beam to be unable to pass through the icing layer and be reflected back to the receiving end at different medium interfaces. This method is almost impossible to be practically applied in a highly polluted environment. The acoustic wave icing sensor is affected by the environmental pollution such as mud in the natural environment in practical application. The surface of the object after being detected is bent and the elastic wave will be offset, causing measurement deviation. In the actual pavement environment, the value is significantly affected by the installation point pavement environment, and the actual measurement surface false positive rate is high. The infrared icing sensor has high requirements for the emission and receiving angles of the infrared beam, and also has high requirements for the reflectivity of the detected environment. Only under the premise of meeting the technical requirements, the icing can be effectively detected. The cost is high, and it is not conducive to wide application. SUMMARY

[0003] The purpose of the present application is to provide a pavement icing detection device and method applied to a road. The detection device can detect pavement icing, the installation will not damage the pavement, and the accuracy will not be affected by the pavement pollution. The price is low, and the application prospect is wide.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0022] Embodiment 1

[0024] The housing 1 is in the shape of a box, and a support bracket 11 is arranged inside the housing 1, and the water storage assembly 3 is arranged on the support bracket 11.

[0025] The capillary water sampling assembly 2 is a capillary bundle; one end of the capillary water sampling assembly 2 extends to the bottom of the housing 1, and the other end is tightly connected with the water storage assembly 3; and the water storage assembly 3 is a capillary material.

[0026] The capillary water sampling assembly 2 and the water storage assembly 3 are capillary materials; one end of the capillary water sampling assembly 2 extends to the bottom of the housing 1, and the other end is tightly connected with the water storage assembly 3.

[0027] The detection assembly comprises an oscillation generator 41 arranged at one end of the water storage assembly 3, an oscillation receiver 42 arranged at the other end of the water storage assembly 3, and a temperature detector 43 arranged on the housing 1.

[0028] The pavement icing detection device further comprises a controller, and the controller is used for controlling the operation of the detection assembly.

[0029] A detection method using the pavement icing detection device, which comprises the following steps: collecting water samples on the ground to the water storage assembly through the capillary water sampling assembly composed of a capillary bundle or a capillary material, and then detecting whether the water storage assembly is frozen through the detection assembly arranged on the water storage assembly, so as to realize pavement icing detection.

[0030] The detection component arranged on the water storage assembly detects whether the water storage assembly is frozen, specifically: a temperature detector detects the real-time air temperature, and judges whether the real-time air temperature is higher than the freezing temperature; an oscillation generator and an oscillation receiver judge whether the water storage assembly is frozen; when the real-time air temperature is lower than the freezing temperature and the oscillation generator and the oscillation receiver judge that the water storage assembly is frozen, it is determined that the pavement is frozen.

[0031] The oscillation generator continuously sends vibration signals, and if the frequency of the vibration signals received by the oscillation receiver is not lower than 80% of the frequency of the vibration signals sent by the oscillation generator, it is determined that the water storage assembly is frozen.

[0032] The frequency of the vibration signals continuously sent by the oscillation generator is 5-45 kHz.

[0033] The oscillation generator and the oscillation receiver are piezoelectric ceramic sheets. The piezoelectric ceramic sheet has inverse piezoelectric effect and positive piezoelectric effect. The oscillation generator utilizes the inverse piezoelectric effect of the piezoelectric ceramic sheet, that is, by applying an alternating voltage of a certain frequency, the sensitive element of the piezoelectric ceramic sheet deforms to produce vibration; the oscillation receiver utilizes the positive piezoelectric effect of the piezoelectric ceramic sheet, that is, the sensitive element of the piezoelectric ceramic sheet vibrates at a certain frequency to generate a certain frequency of current.

[0034] When in use, the pavement freezing detection device is placed on the ground, and the pavement freezing detection can be performed without damaging the ground

[0035] In this embodiment, the water collection assembly 2 composed of capillary action material or capillary bundle extracts water from the pavement based on capillary action and conducts it to the water storage assembly 3 composed of capillary action material, and a detection component is arranged on the water storage assembly 3. Capillary action refers to the attraction of the liquid surface to the solid surface.

[0036] In this embodiment, materials with capillary action are suitable (for example, strip-shaped or block-shaped cloth or similar materials, polyester fiber materials, high-branch high-density canvas, etc.); one end of the water collection assembly 2 is in contact with the pavement, and the other end is separated from the pavement and extends to connect to the water storage assembly 3; according to the capillary action, the water collection assembly 2 can collect water from the pavement to the water storage assembly 3. According to the length and material of the water collection assembly 2, the collection time is 1-5 minutes.

[0037] In this embodiment, the pavement icing detection device and the pavement are in a self-equilibrium state in terms of water content. When there is water on the pavement, the pavement icing detection device will adsorb the water on the pavement onto the water storage component 3 based on capillary action. Conversely, when the pavement is dry but there is still water on the water storage component 3, the water on the water storage component 3 will be drawn off by the dry pavement based on capillary action and / or siphon action, so that the water storage component 3 and the actual water storage situation of the pavement are basically similar. When the temperature is lower than the freezing temperature, the pavement and the water storage component 3 will freeze at the same time.

[0038] Since the water in the water storage component 3 and the ice on the pavement basically occur at the same time, the detection component's ice detection of the water storage component 3 is equivalent to the pavement ice detection. Since the ice determination in this embodiment requires two conditions: the real-time air temperature is lower than the ice temperature and the frequency of the vibration signal received by the oscillation receiver is not lower than 80% of the frequency of the vibration signal emitted by the oscillation generator, the detection results of this embodiment will not be affected by pavement contamination in terms of accuracy.

[0039] Example 2

[0040] A pavement icing detection device, such as Figure 1 As shown, it includes a housing 1, a capillary water sampling component 2, a water storage component 3, and a detection component; the water storage component 3 is disposed inside the housing 1, the capillary water sampling component 2 is tightly connected to the water storage component 3, and the detection component is disposed on the water storage component 3.

[0041] The housing 1 is box-shaped, and a support bracket 11 is provided inside the housing 1. The water storage component 3 is installed on the support bracket 11.

[0042] The capillary water sampling component 2 is a capillary bundle; one end of the capillary water sampling component 2 extends to the bottom of the shell 1, and the other end is tightly connected to the water storage component 3; the water storage component 3 is a capillary material.

[0043] The detection component includes an oscillation generator 41 disposed at one end of the water storage component 3, an oscillation receiver 42 disposed at the other end of the water storage component 3, and a temperature detector 43 disposed on the housing 1.

[0044] The pavement icing detection device also includes a controller, which is used to control the operation of the detection components.

[0045] A detection method using the aforementioned pavement icing detection device: A water sample is collected from the ground into a water storage component by setting up a capillary water sampling component made of capillary bundles or capillary materials, and then a detection component set on the water storage component is used to detect whether the water storage component is icy, thereby realizing pavement icing detection.

[0046] The detection component arranged on the water storage assembly detects whether the water storage assembly is frozen, specifically: a temperature detector detects the real-time air temperature, and judges whether the real-time air temperature is higher than the freezing temperature; an oscillation generator and an oscillation receiver judge whether the water storage assembly is frozen; when the real-time air temperature is lower than the freezing temperature and the oscillation generator and the oscillation receiver judge that the water storage assembly is frozen, it is determined that the pavement is frozen.

[0047] The oscillation generator continuously sends vibration signals, and if the frequency of the vibration signals received by the oscillation receiver is not lower than 80% of the frequency of the vibration signals sent by the oscillation generator, it is determined that the water storage assembly is frozen.

[0048] The frequency of the vibration signals continuously sent by the oscillation generator is 5-45 kHz.

[0049] The oscillation generator and the oscillation receiver are piezoelectric ceramic sheets.

[0050] When in use, the pavement freezing detection device is placed on the ground, and the pavement freezing detection can be performed without damaging the ground.

[0051] In this embodiment, the water collection assembly 2 composed of capillary bundles extracts water from the pavement based on capillary action and conducts it to the water storage assembly 3 composed of capillary materials, and a detection component is arranged on the water storage assembly 3. Capillary action refers to the attraction of the liquid surface to the solid surface.

[0052] In this embodiment, the materials with capillary action are suitable (for example, strip-shaped or block-shaped cloth or similar materials, polyester fiber materials, high-branch high-density canvas, etc.); one end of the water collection assembly 2 is in contact with the pavement, and the other end is separated from the pavement and extends to connect to the water storage assembly 3; according to the capillary action, the water collection assembly 2 can collect water from the pavement to the water storage assembly 3. According to the length and material of the water collection assembly 2, the collection time is 1-5 minutes.

[0053] The water content between the pavement freezing detection device and the pavement in this embodiment is in a self-balancing state; when the pavement has water, the pavement freezing detection device will absorb the water from the pavement to the water storage assembly 3 based on capillary action; on the contrary, when the pavement has dried and the water storage assembly 3 still has water, the water on the water storage assembly 3 will be sucked out by the dry pavement based on capillary action and / or siphon action, so that the actual water storage situation of the water storage assembly 3 and the pavement is basically similar, and when the temperature is lower than the freezing temperature, the pavement and the water storage assembly 3 will freeze at the same time.

[0054] Since the water in the water storage component 3 and the ice on the pavement basically occur at the same time, the detection component's ice detection of the water storage component 3 is equivalent to the pavement ice detection. Since the ice determination in this embodiment requires two conditions: the real-time air temperature is lower than the ice temperature and the frequency of the vibration signal received by the oscillation receiver is not lower than 80% of the frequency of the vibration signal emitted by the oscillation generator, the detection results of this embodiment will not be affected by pavement contamination in terms of accuracy.

[0057] The housing 1 is box-shaped, and a support bracket 11 is provided inside the housing 1. The water storage component 3 is installed on the support bracket 11.

[0058] The capillary water sampling component 2 and the water storage component 3 are made of capillary materials; one end of the capillary water sampling component 2 extends to the bottom of the shell 1, and the other end is tightly connected to the water storage component 3.

[0059] The detection component includes an oscillation generator 41 disposed at one end of the water storage component 3, an oscillation receiver 42 disposed at the other end of the water storage component 3, and a temperature detector 43 disposed on the housing 1.

[0060] The pavement icing detection device also includes a controller, which is used to control the operation of the detection components.

[0061] A detection method using the aforementioned pavement icing detection device: A water sample is collected from the ground into a water storage component by setting up a capillary water sampling component made of capillary bundles or capillary materials, and then a detection component set on the water storage component is used to detect whether the water storage component is icy, thereby realizing pavement icing detection.

[0062] The method of detecting whether the water storage component is frozen by means of a detection component installed on the water storage component is as follows: a temperature detector is used to detect the real-time air temperature and determine whether the real-time air temperature is higher than the freezing temperature; an oscillation generator and an oscillation receiver are used to determine whether the water storage component is frozen; when the real-time air temperature is lower than the freezing temperature and the oscillation generator and the oscillation receiver determine that the water storage component is frozen, the pavement is determined to be frozen.

[0063] The method of determining whether the water storage component is frozen by using an oscillation generator and an oscillation receiver is as follows: the oscillation generator continuously emits a vibration signal, and if the frequency of the vibration signal received by the oscillation receiver is not less than 80% of the frequency of the vibration signal emitted by the oscillation generator, it is determined that the water storage component is frozen.

[0064] The frequency of the vibration signal continuously generated by the oscillation generator is 5-45 kHz.

[0065] The oscillation generator and the oscillation receiver are piezoelectric ceramic sheets.

[0066] In use, the pavement icing detection device is placed on the ground, and the pavement icing detection can be performed without damaging the ground.

[0067] In this embodiment, the water collection assembly 2 composed of capillary materials or capillary bundles extracts water from the pavement based on capillary action and conducts it to the water storage assembly 3 composed of capillary materials, and a detection assembly is provided on the water storage assembly 3. Capillary action refers to the attraction of the liquid surface to the solid surface.

[0068] In this embodiment, materials with capillary action are suitable (for example, strip-shaped or block-shaped cloth or similar materials, polyester fiber materials, high-branch high-density canvas, etc.); one end of the water collection assembly 2 is in contact with the pavement, and the other end is separated from the pavement and extends to connect to the water storage assembly 3. According to the capillary action, the water collection assembly 2 can collect water from the pavement to the water storage assembly 3. According to the length and material of the water collection assembly 2, the collection time is 1-5 minutes.

[0069] The water content between the pavement icing detection device and the pavement in this embodiment is in a self-balancing state. When the pavement has water, the pavement icing detection device will adsorb the water from the pavement to the water storage assembly 3 based on capillary action. Conversely, when the pavement has dried and there is still water in the water storage assembly 3, the water in the water storage assembly 3 will be drawn out by the dry pavement based on capillary action and / or siphon action, so that the actual water storage conditions of the water storage assembly 3 and the pavement are basically similar, and the pavement and the water storage assembly 3 will freeze at the same time when the temperature is lower than the freezing temperature.

[0070] Since the water in the water storage assembly 3 and the pavement freezing occur at basically the same time, the freezing detection of the water storage assembly 3 by the detection assembly is equivalent to the freezing detection of the pavement. Since the freezing determination in this embodiment requires two conditions that the real-time air temperature is lower than the freezing temperature and the frequency of the vibration signal received by the oscillation receiver is not lower than 80% of the frequency of the vibration signal generated by the oscillation generator, the detection result of this embodiment will not be affected by the accuracy of the pavement pollution.

[0076] The pavement icing detection device also includes a controller, which is used to control the operation of the detection components.

[0077] A detection method using the aforementioned pavement icing detection device: A water sample is collected from the ground into a water storage component by setting up a capillary water sampling component made of capillary bundles or capillary materials, and then a detection component set on the water storage component is used to detect whether the water storage component is icy, thereby realizing pavement icing detection.

[0078] The method of detecting whether the water storage component is frozen by means of a detection component installed on the water storage component is as follows: a temperature detector is used to detect the real-time air temperature and determine whether the real-time air temperature is higher than the freezing temperature; an oscillation generator and an oscillation receiver are used to determine whether the water storage component is frozen; when the real-time air temperature is lower than the freezing temperature and the oscillation generator and the oscillation receiver determine that the water storage component is frozen, the pavement is determined to be frozen.

[0079] The method of determining whether the water storage component is frozen by using an oscillation generator and an oscillation receiver is as follows: the oscillation generator continuously emits a vibration signal, and if the frequency of the vibration signal received by the oscillation receiver is not less than 80% of the frequency of the vibration signal emitted by the oscillation generator, it is determined that the water storage component is frozen.

[0080] The vibration signal continuously emitted by the oscillator has a frequency of 10k-12kHz.

[0081] The oscillation generator and oscillation receiver are piezoelectric ceramic sheets.

[0082] To use, simply place the pavement icing detection device on the ground to detect pavement icing without damaging the ground.

[0083] In this embodiment, the water sampling assembly 2, composed of capillary bundles, extracts moisture from the pavement based on capillary action and conducts it to the water storage assembly 3, which is composed of a capillary action material.

When the temperature is lower than the freezing temperature, the pavement and the water storage component 3 will freeze at the same time.

[0086] Since the water in the water storage component 3 and the ice on the pavement basically occur at the same time, the detection component's ice detection of the water storage component 3 is equivalent to the pavement ice detection. Since the ice determination in this embodiment requires two conditions: the real-time air temperature is lower than the ice temperature and the frequency of the vibration signal received by the oscillation receiver is not lower than 80% of the frequency of the vibration signal emitted by the oscillation generator, the detection results of this embodiment will not be affected by pavement contamination in terms of accuracy.
