Description

Technical Field

[0001] The present invention relates to the field of traffic disaster prevention and reduction, and in particular to an intelligent road ice and snow melting disaster prevention and reduction system using green electricity energy. Background Art

[0002] In my country's current transportation industry, due to the objective conditions of high latitude and high altitude, or extreme climate, some areas often experience large-scale traffic interruptions due to snow and ice on the road or runway, and even worse, traffic accidents, threatening people's lives. In response to this, the industry has adopted a variety of measures to remove ice and snow, such as traditional methods such as snowplows, snowblowers, and salting, but these measures generally have the disadvantages of difficult deicing, low efficiency, and high cost. In particular, they cannot change the objective fact that traffic has been affected. They are ex post measures and cannot prevent them in advance. Some measures also try to add heating components to the structural layer of the road to heat the road surface by heat conduction, heat radiation, etc., but because the added heating components are easy to destroy the bonding between the original structural layers of the road, after repeated rolling by vehicles, the surface layer of the road creeps and the structural layers separate, which greatly reduces the life of the road. At the same time, the damage to the road surface causes the damage to the heating components and then fails, and the practical value is low. Therefore, there is an urgent need for a snow and ice removal solution that has no negative impact on the road structure. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, that is, when a heating component is buried in the road surface to melt ice and snow, the buried heating component will destroy the road structure and the bonding between layers, and quickly cause damage to the road surface after being rolled over by vehicles. The present invention provides a road intelligent ice and snow melting disaster prevention and mitigation system using green electricity energy, which will not have a negative impact on the road surface but is beneficial to it, and maximizes the use of clean energy and realizes automatic operation and intelligent control.

[0004] The present invention provides a road intelligent snow and ice melting disaster prevention and reduction system using green electricity energy, comprising:

[0005] The alternating magnetic field snow and ice melting subsystem comprises a road surface structure and a plurality of alternating magnetic field generators. The road surface structure is mixed with metal conductors, which are beneficial to the quality index of the road surface structure.

[0006] The alternating magnetic field generator includes an excitation coil. A plurality of the alternating magnetic field generators are evenly arranged on the side of the road. The excitation coil generates a continuous alternating magnetic field. The alternating magnetic field causes the metal conductor to generate eddy current effect and generate heat, thereby melting ice and snow on the road surface.

[0007] The present invention provides a road intelligent snow and ice melting disaster prevention and mitigation system using green electricity energy. The excitation coil in the alternating magnetic field generator can generate and release an alternating magnetic field to the surrounding environment. When the alternating magnetic field acts on the metal conductor in the road, an eddy current effect will be induced inside the metal conductor, causing the metal conductor to continue to heat up. After the metal conductor is heated, it can transfer heat energy to the road surface structure. When the surface of the road surface structure is covered with snow or ice, the heat of the road surface structure will be further transferred to the ice and snow, and finally the purpose of automatically melting the road surface ice and snow is achieved. The alternating magnetic field generator is arranged on the side of the road, rather than in the structure of the road, and will not have a negative impact on the road structure and the bonding between layers. At the same time, the metal conductor has good tensile and compressive properties. It is added to the cement concrete and asphalt concrete of the road surface structure according to the mix ratio design, and can also enhance the bonding and overall strength between the layers of the road surface structure. Therefore, while solving the snow melting effect of the road surface, the present invention will not have a negative impact on the road surface, but will be beneficial to it, avoiding the problem of shortening the service life of the road surface.

[0008] The metal conductor is one or more of steel fiber, iron block, iron wire, copper wire or iron filings, the steel fiber can be straight steel fiber, pressed ridge steel fiber, corrugated steel fiber or hooked steel fiber, the iron wire and the copper wire can be wavy or annular, the iron block is a regular or irregular block with a particle size of 2mm to 15mm. The amount of the metal conductor added to the road surface structure can be uniformly distributed or can vary laterally along the road, for example, the farther away from the roadside alternating magnetic field generator, the higher the amount of the metal conductor added.

[0009] The alternating magnetic field generators may be installed on only one side of the road, or may be installed on both sides of the road at the same time. When the alternating magnetic field generators are installed on only one side of the road, the alternating magnetic field generators are evenly arranged along the length of the road; when the alternating magnetic field generators are installed on both sides of the road at the same time, the alternating magnetic field generators on both sides are evenly arranged along the length of the road, and the alternating magnetic field generators on both sides may be symmetrically arranged along the center line of the road, or may be arranged in a staggered manner along both sides of the road. The alternating magnetic field generators may be arranged on the ground on both sides of the road, or may be attached to the road facilities on both sides of the road.

[0010] The excitation coil in the alternating magnetic field generator is formed by tightly and orderly winding a metal wire around the central axis of the excitation coil; the central axis is not fixed, it can be a straight line segment or a curved U-shaped structure; the excitation coil can be a single form, or a combination of multiple forms and multiple numbers, all for the purpose of enhancing and evenly distributing the magnetic field strength at a certain distance outside the coil. When the excitation coil is energized, magnetic lines of force will be generated in the space around it. The magnetic lines of force start from one end of the excitation coil, pass through the space along a specific direction, and finally return to the other end of the excitation coil, forming a complete magnetic line of force loop.

[0011] Preferably, a plurality of the alternating magnetic field generators are arranged in a staggered manner along both sides of the road, and this solution enables the alternating magnetic field to more effectively cover the area of ​​the road. The excitation coil includes a U-shaped or a combined type, wherein the U-shaped coil has a U-shaped central axis, and the opening of the U-shaped coil faces the center line of the road; the combined type includes a plurality of independent coils, and each of the independent coils is provided with an iron core. In this solution, after the excitation coil is energized, the magnetic lines of force generated in the space around it can point more toward the direction of the U-shaped opening, so that the magnetic lines of force can act more fully on the road, thereby improving the utilization efficiency of the alternating magnetic field generated by the excitation coil. The iron core can further enhance the intensity of the alternating magnetic field generated by the excitation coil, improve the efficiency of heating the metal conductor, and thus accelerate the melting of ice and snow on the road.

[0012] Preferably, the content of the metal conductor in the road surface structure will gradually increase as the position gradually moves away from the alternating magnetic field generator. This is because the farther the area is from the alternating magnetic field generator, the weaker the magnetic field strength. In order to reduce the difference in heat generation in the lateral direction of the road, a higher content of the metal conductor is added in the area far away from the alternating magnetic field generator, while less is added in the area close to the alternating magnetic field generator. This scheme accurately controls the amount of the metal conductor added in different areas of the road according to the distribution law of the magnetic field, thereby more effectively utilizing the metal conductor, ensuring uniform heating of the road and avoiding unnecessary waste of the metal conductor. In the road, the content of the metal conductor can be continuously changed or in steps. The material type of the metal conductor is steel fiber, iron ball, iron block or iron filings.

[0013] Preferably, the installation forms of the alternating magnetic field generator include attached type and integrated type; the attached type is that the alternating magnetic field generator is attached and installed on road facilities, and the road facilities include anti-collision guardrails, anti-glare panels, and sound barriers. The attached type is suitable for retrofitting existing road facilities; the integrated type is that the alternating magnetic field generator is directly integrated with the road facilities during production to form an integral product. The integrated type is suitable for newly built road facilities.

[0014] Preferably, the alternating magnetic field snow and ice melting subsystem is equipped with a wind-solar green electricity supply subsystem, which includes a self-powered module and a power storage module. The self-powered module is used to power the alternating magnetic field generator, and the self-powered module is connected to an external power grid to realize power supply; the self-powered module includes a wind power generation component and a solar power generation component, which can realize continuous self-power supply; the power storage module is used to store energy as a supplementary power supply when self-generation is insufficient. The wind power generation component includes a complete set of necessary equipment such as wind blades, motors, and rectifiers, and the solar power generation component includes a complete set of necessary equipment such as photovoltaic panels, inverters, and concentrators. The wind blades of the wind power generation component adopt vertical axis blades or horizontal axis blades, and the photovoltaic panels of the solar power generation component adopt thin-film solar cells or crystalline silicon solar cells.

[0015] The self-powered module is powered by its own wind power generation components and solar power generation components, making full use of light energy, solar energy, strong convective snow and wind power generation in weather and vehicle driving, and can provide uninterrupted green power supply in a variety of scenarios.

[0016] Preferably, the installation forms of the wind blades of the wind power generation component and the photovoltaic panels of the solar power generation component include attachment type and integration type; the attachment type is to attach the wind blades and the photovoltaic panels to the road facilities, and the road facilities include anti-collision guardrails, anti-glare panels, and sound barriers. The attachment type is suitable for the installation of existing road facilities; the integration type is to directly integrate the wind blades and the photovoltaic panels with the road facilities during production to form an integral product, or directly use crystalline silicon or thin-film solar photovoltaic materials to make anti-glare panels and sound barriers as the solar power generation components, or directly use solar photovoltaic materials to make the wind blades. The integration type is suitable for newly built road facilities.

[0017] The wind blades are preferably arranged at higher positions with strong airflow, such as the top of the anti-collision guardrail and the position between the sound barriers, so as to better absorb wind energy. They can also be directly combined with the anti-collision guardrail posts and the sound barriers. When the anti-collision guardrail and the sound barrier are blocked by greenery or there is insufficient space, the wind blades can be combined with the alternating magnetic field generator and attached to the roadside facilities such as the anti-collision guardrail posts. The wind blades are preferably vertical-axis blades, but horizontal-axis or combined blades can also be used.

[0018] The photovoltaic panels preferably use amorphous silicon thin-film solar panels with good weak-light power generation performance and low temperature coefficient, and use anti-glare panels and sound barriers made of crystalline silicon or thin-film solar panels as light power generation components; the photovoltaic panels can also be installed independently at locations with good light conditions, or installed in the form of an alternating magnetic field generator housing; the thin-film solar panels can also be integrated with wind blades, that is, thin-film solar panels are used as wind blades.

[0019] Preferably, the alternating magnetic field snow melting subsystem is equipped with an intelligent control subsystem, which includes a control module and a radio transceiver module. The control module can turn on or off the alternating magnetic field generator, and adjust and control the voltage, current and power. The radio transceiver module is used for communication to achieve remote control. This solution is used for the communication and control of the background master control terminal with a single or multiple devices, and the control content is the corresponding turn on or off of the alternating magnetic field generator, and the adjustment of current, voltage or power.

[0020] Preferably, the control module is configured with a temperature sensing element, a memory and an indicator light. The temperature sensing element can obtain the temperature of the road surface structure and provide the control module with road surface temperature information; the memory can be used to write, input and store management information data, and the management information data includes the three-dimensional geodetic coordinate data of the location of the control module itself; the indicator light can reflect the working status of the alternating magnetic field generator.

[0021] The temperature sensing element is arranged close to the road surface structure to obtain the temperature information of the road surface more accurately, and feeds back the obtained temperature information to the control module. The indicator light can prompt the observer and the manager of the working state of the alternating magnetic field generator at this time, which are: normal working state, stop working state and fault state, which is helpful to timely inspect and maintain the alternating magnetic field generator.

[0022] Preferably, the road surface temperature information collected by the control module and the stored management information data can be read by the radio transceiver module of the control module of the adjacent device, and the information data storage and real-time reading behavior between multiple adjacent intelligent control subsystem control modules form an uninterrupted communication data chain; the geodetic three-dimensional coordinate data of the storage device can also be read by vehicle-mounted equipment with radio reception function to assist in real-time vehicle positioning.

[0023] The information and data stored in the memory can be read by the radio transceiver modules of adjacent devices, so that all the control modules on the road are connected in series, thereby forming an uninterrupted communication data chain. The unique three-dimensional coordinate data of the device in the data can also be read by the on-board equipment with radio receiving function to assist the real-time positioning of passing vehicles; the information and data running in the data chain include the three-dimensional coordinate changes of each device. Under the uninterrupted wind and solar power supply and power storage module power supply, the data chain can operate sustainably. When the data chain crosses a tunnel project that does not require ice and snow melting, it can be powered by the power system configured by the tunnel project, and a communication connection device can be set in the tunnel to ensure that the data chain is uninterrupted; the communication connection device in the tunnel also has a memory and its three-dimensional coordinate information of the earth, which can provide a positioning basis for the vehicle in the tunnel.

[0024] Preferably, the uninterrupted communication data link formed by the radio transceiver module and the control module is ultimately connected to a background master control terminal, which turns on or off the alternating magnetic field generator of different road sections and adjusts the voltage, current and power as needed to achieve remote control; the background master control terminal monitors equipment damage or road damage based on changes in real-time measurement values ​​of the three-dimensional coordinates of any device provided by the data link, and provides disaster prevention and mitigation warnings.

[0025] Based on the continuous operation of the data link and signal relay transmission, the background master control terminal can provide the background master control terminal with remote control and monitoring of multiple devices or any single device in any road section. The background master control terminal can turn on or off the alternating magnetic field generators in different road sections, adjust the voltage, current and power, and realize remote control according to the information provided by the temperature sensing element or meteorological information; the background master control terminal can monitor the damage or movement of equipment and road damage according to the changes in the real-time measurement values ​​of the three-dimensional coordinates of any device provided by the data link, and provide disaster prevention and mitigation warnings.

[0026] The background master control terminal adopts two forms in turn: one is a terminal control system installed in the road management department, which can be remotely controlled and integrated with other existing road monitoring systems; the other is a movable and portable controller or control box with its own battery, which serves as a supplement to the indoor control terminal and is used for emergency response control, on-site debugging, or on-site input of three-dimensional coordinate data, numbers and other information for newly installed devices.

[0027] Based on the above detailed description, the operation mechanism of the present invention is summarized as follows: when the weather is fine, the alternating magnetic field generator is in a closed state to avoid the alternating magnetic field from interfering with the electronic equipment of the passing vehicles; but the data link based on the wind and solar power generation and the power storage module is in operation to maintain the communication, vehicle positioning, and disaster prevention warning functions. When the weather forecast indicates that a certain area of ​​the road is about to encounter ice and snow weather, the background master control terminal can send an opening instruction to the control module of the snowfall area section on the road. After the control module receives the instruction, the alternating magnetic field generator is turned on; after the temperature sensing element confirms that the road section has been at a certain safe temperature for a long time, or after on-site observation that the ice and snow have melted, the background master control terminal turns off all or part of the alternating magnetic field generator through the data link. This solution can heat the road in advance before the arrival of ice and snow weather, and when the ice and snow contact the heated road surface, they will melt quickly, thereby greatly reducing the risk of ice and snow accumulation on the road. This solution improves the safety of vehicles passing through the road and effectively prevents traffic accidents caused by ice and snow coverage. At the same time, the solution also avoids the lag and inefficiency of taking heating measures to remove ice and snow after they accumulate on the road, ensuring the initiative and timeliness of road maintenance.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention provides an intelligent road ice and snow melting disaster prevention and mitigation system for green electricity energy. It adopts the method of adding metal conductors that are beneficial to quality indicators into the road surface structure, and arranging an alternating magnetic field generator on the road side to avoid arranging components that are objectively detrimental to the road surface quality indicators in the road surface structure. It will not damage the road surface structure and interlayer adhesion, and will not shorten the service life of the road surface, ensuring that there is no negative impact on the original road surface structure. This premise makes the implementation of the ice and snow melting of the present invention have objective and practical practical value.

[0030] 2. The present invention provides an intelligent road ice and snow melting disaster prevention and mitigation system using green electricity energy. Its alternating magnetic field ice and snow melting subsystem uses the eddy current principle. The roadside alternating magnetic field generator causes the metal conductor in the road surface layer to heat up due to the eddy current effect, achieving the effect of instant ice and snow melting without forced traffic interruption.

[0031] 3. The present invention provides an intelligent road ice and snow melting disaster prevention and mitigation system using green electricity energy. The wind and solar green electricity supply subsystem has wind and solar power generation components, which utilize light energy, especially wind energy generated by car driving and severe convective weather, to achieve self-power supply. It does not rely on external power supply, thereby ensuring the continuity and stability of ice and snow melting, while greatly reducing operating costs. It is low-carbon and environmentally friendly, and easy and convenient to maintain and replace.

[0032] 4. The present invention provides an intelligent road ice and snow melting disaster prevention and mitigation system using green electricity energy. Based on the continuous self-power supply capability of the wind and solar green electricity supply subsystem, as well as the radio transceiver function and data storage function, an uninterrupted data link is established, and the automatic operation and intelligent control of the system are realized, and it has a high practical value for vehicle positioning and disaster prevention and early warning.

[0058] In an optional embodiment, a plurality of alternating magnetic field generators 1 may be arranged in a staggered manner along both sides of the road. Figure 2 As shown, a plurality of alternating magnetic field generators 1 are evenly distributed at certain intervals along both sides of the road, but the alternating magnetic field generators 1 on each side are offset from the adjacent alternating magnetic field generators 1 on the other side by half an interval, forming a staggered layout.

[0072] In an optional embodiment, the control module may be configured with a temperature sensing element, a memory and an indicator light, wherein the temperature sensing element may obtain the temperature of the road surface structure 2 and provide the control module with road surface temperature information. The memory may be used to write, input and store management information data, wherein the management information data includes the three-dimensional coordinate data of the location of the control module itself; the indicator light may reflect the working status of the alternating magnetic field generator 1.

[0073] The management information data may also include: temperature information, the working state of the alternating magnetic field generator 1, the power supply status of the self-powered module and other data.

[0074] The temperature sensing element can be specifically arranged on the column of the anti-collision guardrail near the road surface structure 2, at a height of 2mm-5mm from the ground, for continuously monitoring the road surface temperature at the current location.

[0075] The indicator light can be set to three lighting states, namely green, red and yellow. When the indicator light is green, it means that the alternating magnetic field generator 1 is in a normal working state; when the indicator light is red, it means that the alternating magnetic field generator 1 is in a stopped working state; when the indicator light is yellow, it means that the alternating magnetic field generator 1 is in a fault state.

[0076] In an optional embodiment, the road surface temperature information and stored management information data collected by the control module can be read by the radio transceiver module of the adjacent intelligent control subsystem, and the data storage and reading behaviors between multiple adjacent devices form an uninterrupted communication data chain; the three-dimensional geodetic coordinate data of the memory can also be read by vehicle-mounted equipment with radio reception function, to assist in real-time vehicle positioning.

[0077] In an optional implementation, the uninterrupted communication data link formed by the radio transceiver module and the control module can eventually be connected to a background master control terminal, which can turn on or off the alternating magnetic field generator 1 of different road sections, adjust the voltage, current and power as needed, and realize remote control. The background master control terminal monitors the damage of equipment or road damage based on the real-time measurement value of the three-dimensional coordinates of any device provided by the data link, and provides disaster prevention and mitigation warnings. The background master control terminal can realize wireless communication connection with the corresponding control module through the radio transceiver module.

[0078] Specifically, the background master control terminal is set at one end of the road extension line and establishes communication with the control module closest to the background master control terminal, which can be called the starting control module. The starting control module will forward the data it receives from the background master control terminal to the next adjacent control module. This process will be carried out continuously between adjacent control modules, and each control module plays the role of a relay station to transmit data from one end to the other.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
