Clean Road and Snow Removal System using online integrated management

The present invention uses an infrared camera, a radar, and an integrated sensor to understand the situation of the road, and to spray the road with washing water or snow removal agent to wash the road, or to remove snow removal or black ice, an online integrated management clean road and snow removal system. About.

In the case of roads, a lot of pollutants are accumulated due to accumulation of fine dust in the atmosphere or fine dust generated by the wear of the road surface and tires due to friction with the vehicle's tires according to the vehicle's passage. It is scattered into the atmosphere by the running wind or wind caused by the passage of the vehicle and acts as a cause of air pollution. Accordingly, there is a need for a road cleaning system that can effectively clean a road surface.

In addition, recently, due to problems such as climate change, it is difficult to accurately predict major weather information such as temperature, precipitation, and snowfall, and unexpected surprise heavy snowfall occurs in winter, or effective measures to resolve snow removal or freezing due to a sudden temperature drop. There are practical limits to establishing.

In addition, Korea has a lot of snowfall in winter due to seasonal influences, and due to the nature of the mountainous terrain, flooding and freezing occur frequently on the road.At night, it is not easy to check the condition of the road with the naked eye compared to the daytime, and the frozen part is It is known that most of winter driving accidents are caused by road icing because it is not easily visible to the driver's eyes.

In particular, black ice is a phenomenon in which transparent ice covers the asphalt as if it was coated on the asphalt, and to the driver's eyes it appears as dry black without ice on the road. It is not conspicuous when driving on the road, and the road appears to be just wet. Because it is slippery, it makes it difficult to control the vehicle, which causes a major accident in winter.

Black ice is known to be formed by maintaining a supercooled state that does not freeze even when raindrops fall below freezing point in winter, and then freezes instantly as it falls to the surface, or is formed by freezing black after soot and dust in the air entangled with snow and moisture. have.

Recently, as part of countermeasures against the occurrence of black ice, when snow or rain is expected, and when the temperature of the road surface is 3°C or less, pre-spray the snow removal agent 1 to 2 hours before the generation of black ice. Although it is supposed to be prevented, there is a problem that it is difficult to prevent when an excessive amount of snow removal agent is not applied to the road surface, and there is a problem that sufficient prevention is difficult simply by applying a snow removal agent such as calcium chloride.

In addition, conventionally, when freezing occurs on the road surface such as black ice using CCTV, GPS signals, etc., a method of visually checking is used, but this method has a problem that it is difficult to accurately detect the condition of the road surface. There is a need for research on ways to supplement this.

Hereinafter, the present invention will be described in detail.

1 is a conceptual diagram showing an online integrated management type clean rod and snow removal system 10 according to the present invention.

Referring to FIG. 1, the online integrated management type clean rod and snow removal system 10 (hereinafter referred to as “clean rod and snow removal system 10”) according to the present invention includes a washing water spraying unit 100; An integrated sensor unit 200; An image acquisition unit 300; Radar observation unit 400; Communication unit 500; And a remote integrated management server unit 600;

Looking at the configuration of the clean road and snow removal system 10 according to the present invention according to the present invention, the washing water spraying unit 100 sprays washing water on the road to wash and remove pollutants from the road surface, and snowfall occurs. When ice or black ice is generated on the road, or by spraying washing water containing a snow removal agent or friction material on the part where it is expected to be generated, snow removal and melting can be performed, or freezing or slipping can be prevented. The type, concentration, and supply amount of the friction material can be controlled and sprayed, so it can be formed in a structure that can respond appropriately to road conditions.

To this end, the washing water spraying unit 100 is a conventional various types of washing water spraying device including a washing water storage tank for storing the washing water, a deicing agent storage tank for supplying a deicing agent, and a washing water spreader for spraying a mixed liquid type of washing water. It can be introduced and formed.

Preferably, the washing water spraying unit 100 has a structure including a washing water storage tank 110, a deicing agent storage tank 130, a storage tank 150 and a washing water spreader 170, and additionally a friction material spreader 190. Have.

Specifically, the washing water storage tank 110 may be installed close to a road, and may be disposed at an appropriate position to remove a pre-set division of a jurisdiction. In addition, a receiving space is formed inside to perform road washing, snow removal, or melting, or to store washing water to prevent freezing or slipping, and a snow removal agent supply pipe ( 111), the water supply pipe 151, the friction material supply pipe 191 are connected to store the washing water generated by mixing with water by receiving the deicing agent or friction material from the deicing agent storage tank 130 and the friction material storage tank 190, which will be described later. I can. In addition, the washing water storage tank 110 may receive water through a water supply pipe 151 that supplies water to the other side and store only water as washing water. In addition, a washing water discharge hole for supplying washing water is formed on one side, and is connected to a washing water transfer pipe or a washing water pumping pipe to be described later to supply washing water to the washing water spreader 170 to be described later.

In addition, the washing water storage tank 110 may further include a capacity detection sensor 115 for detecting the capacity of the stored liquid deicing agent to continuously detect the capacity of the deicing agent contained in the stored washing water.

In addition, the washing water storage tank 110 may have a structure further including an air inlet 117 penetrating the inside and outside at a relatively higher upper portion, and the air inlet 117 is an interior of the washing water storage tank 110. And it serves to communicate with the outside, thereby forming a structure in which air in the atmosphere naturally flows into the interior of the washing water storage tank 110.

In the washing water spraying unit 100, the deicing agent storage tank 130 serves to supply the deicing agent to the washing water storage tank 110. To this end, the snow removal agent storage tank 130 is formed with a water supply pipe 131 for supplying water to one side and an inlet 133 for supplying snow removal agent to receive water and snow removal agent, and a receiving space is formed therein. It is possible to prepare a snow removal agent by mixing the snow removal agent and water, and the prepared snow removal agent can be supplied to the washing water storage tank (110). In addition, the deicing agent storage tank 130 may have a structure including a stirring means therein so as to continuously agitate the deicing agent and water to produce a deicing agent having a uniform concentration.

In the washing water spraying unit 100, the storage tank 150 is buried and installed underground to collect rainwater or receive water from tap water and store it as water, and then the washing water storage tank 110, the deicing agent storage tank 130 Alternatively, a pipe connection may be configured to supply water to the friction material storage tank 190.

The washing water spraying unit 100 having the above structure allows the storage tank 150 to collect and use rainwater, thereby significantly reducing the cost of using water for road washing, snow removal, melting, freezing, or slip prevention. , When constructing the clean rod and snow removal system 10, the aesthetic impact on the environment can be minimized.

In addition, the amount of water, snow removal agent, friction material, etc. supplied to the washing water storage tank 110 may be adjusted according to the condition of the road surface, weather, and the like. Therefore, the clean rod and snow removal system 10 according to the present invention having the above-described configuration, the washing water storage tank 110 to spray a high concentration of snow removal agent when the temperature of the road at the cleaning site drops sharply or the snow amount increases due to high snowfall. If the concentration of the snow removal agent can be controlled, and when the road temperature at the snow removal site is relatively high or the amount of snowfall is relatively low, spray a low concentration of snow removal agent to prevent misuse of snow removal agent and perform appropriate snow removal work. .

The clean rod and snow removal system 10 according to the present invention is a chloride-based snow removal agent including sodium chloride (NaCl), calcium chloride (CaCl ₂ ), magnesium chloride (MgCl ₂ ), or a mixture thereof as a snow removal agent, such as tap water, groundwater, etc. What is prepared by mixing with water can be used, calcium magnesium acetate (CMA), calcium magnesium of organic acids (CMO), potassium acetate (CH ₃ COOK), acetic acid, calcium carbonate, glycerin, It is also possible to use one prepared by mixing an organic-based snow removal agent including urea or a mixture thereof with water such as tap water or ground water.

The above-described snow removal agents exhibit different properties depending on the type and concentration of the snow removal agent contained in the snow removal agent.

For example, when a 10% calcium chloride aqueous solution is used as a snow removal agent used at a snow removal site, the 10% calcium chloride aqueous solution may induce snow removal and melting effects below -4 °C, and does not freeze even if a separate thermal insulation equipment is not provided. When the 20% calcium chloride aqueous solution is less than -11.5° C., the snow removal and melting effect may be induced, and when the road temperature or ambient temperature falls below the temperature, the snow removal and melting effect is difficult to induce in a short time.

In addition, when a 10% sodium chloride aqueous solution is used as the snow removal agent, the 10% sodium chloride aqueous solution may induce snow removal and melting effects below -6.5 °C, and a 20% calcium chloride aqueous solution may induce snow removal and melting effects below -17.5 °C. When a 10% potassium acetate aqueous solution is used as a snow removal agent, the 10% potassium acetate aqueous solution may induce snow removal and melting effects below -2 °C, and a 20% potassium acetate aqueous solution below -5 °C And a melting effect can be induced.

Therefore, the snow removal agent exhibits different characteristics in realization of the snow removal and melting effect depending on the type of snow removal agent used for the production of the snow removal agent and the concentration of the snow removal agent, and the section in which the snow removal agent freezes according to the temperature of the road at the snow removal site is also concentrated. Each exhibits different characteristics.

However, conventionally, by providing a single washing water storage tank 110 to supply the deicing agent, it is inevitable to supply the deicing agent of a uniform concentration, so that the deicing agent is excessively used, or a low-concentration deicing agent is used to prevent this. When used, there is a problem that it is difficult to perform the snow removal operation because the stored snow removal agent freezes when the temperature drops rapidly.

In addition, in general, snow removal ^{is set to spray 1 L of snow removal agent in an area of 1 m 2} for snow removal, and a snow removal agent storage tank with a capacity of about 10,000 L is introduced to store the snow removal agent. I am doing it.

Considering that the width of a general one-lane road in Korea is 7 m, the snow removal agent spreader is usually installed at 500 m intervals, and is used for one time snow removal in consideration of the width and installation distance of such roads. About 3,500 L of the deicing agent is sprayed to remove the snow, and in the case of a conventional deicing agent storage tank, the deicing agent must be resupplied to the deicing agent storage tank after spraying about 3 times. The snow removal agent is sprayed by checking the thickness of the snow, controlling the concentration of the snow removal agent by thickness, or controlling the number of sprays.

In addition, the injection of snow removal agent is controlled according to the amount of snowfall. For example, when snowfall is 5 mm, 3 cm, and 8 cm, the snow removal site is made to be sprayed once at a time. There is a problem that effective snow removal in a short time becomes difficult because it is completely consumed, and when a snow removal agent containing a low concentration of snow removal components is sprayed, the snow removal effect is insufficient, and when the temperature drops sharply, it is difficult to induce sufficient melting and ice effects. I can.

In addition, when the snow removal agent stored in the washing water storage tank 110 uses a high-concentration snow removal agent, a high-concentration snow removal agent is sprayed even when the snowfall is low, so that the snow removal agent is sprayed with an excessive concentration compared to the amount of snow removal or melted ice, thereby corroding roads and structures. In addition, problems that cause environmental pollution may occur.

Therefore, the clean road and snow removal system 10 according to the present invention can optimize the snow removal effect and the amount of snow removal agent used by using washing water containing an appropriate concentration of snow removal agent according to the snow amount of the snow removal site and the road temperature conditions. According to this, it is possible to implement a customized snow removal method capable of controlling the snow removal time of the road by adjusting the capacity of the snow removal agent included in the washing water.

That is, the clean rod and snow removal system 10 according to the present invention is appropriate by supplying a high concentration of snow removal agent from the snow removal agent storage tank 130 so that the concentration of the snow removal agent is increased in the washing water stored in the washing water storage tank 110. It can be configured to induce a sufficient snow removal effect while realizing the melting effect, and to prevent freezing of the washing water stored in the washing water storage tank 110, thereby preventing a decrease in the driving power of the clean rod and the snow removal system 10 due to temperature changes. To be able to.

In addition, when the road temperature is -5 to -1 ℃ to the snow removal site, water is supplied to the washing water storage tank 110 to reduce the concentration of the snow removal agent, and to spray the snow removal agent whose concentration has been lowered as described above. So you can perform snow removal.

In addition, the clean rod and snow removal system 10 provided with the washing water spraying unit 100 as described above may form a structure that prevents freezing of the washing water storage tank 110 due to a rapid temperature drop. As an example, the washing water storage tank 110 may store a 10% calcium chloride aqueous solution as washing water, and the washing water storage tank 110 freezes the washing water when the external temperature is less than -4 °C to remove the deicing agent on the road. It may be difficult to supply smoothly, but if a 20% calcium chloride aqueous solution is used as washing water, it is not frozen even at -11.5 ℃ and can be maintained in a safe state.

In addition, when the road temperature at the site falls below -20°C, a high-concentration snow removal agent is supplied to the washing water storage tank 110, and a high-concentration snow removal agent is sprayed as described above so that the snow removal work can be performed. Accordingly, it is possible to minimize the snow removal efficiency and consumption of the snow removal agent. The washing water storage tank 110 as described above can be stably driven even in a low-temperature environment of -20°C or lower and introduced to the road snow removal site and used, and can minimize adverse effects such as environmental pollution and corrosion by minimizing the consumption of snow removal agent. have.

Preferably, the deicing agent mixed with the washing water may be a mixture of calcium chloride and water, or a mixture of magnesium chloride and water, and more preferably, an aqueous solution containing 10 to 20% by weight of calcium chloride and the rest of water Can be used.

The washing water sprayer 170 including the labeling bottle portion 181 acting as a washing water spraying nozzle in the washing water spraying unit 100 serves to spray washing water onto the road, and cleans the washing water supplied from the washing water storage tank 110 or It is also possible to introduce and use various types of conventional spray nozzle structures that spray on snow removal sites.

Further, the washing water spraying unit 100 according to the present invention can spray the washing water for snow removal when snow removal work is required on the road due to snowfall, and change the type of the snow removal agent to prevent accidents caused by black ice and freezing. Therefore, it may be driven to spray the mixed washing water for countering black ice and freezing with the washing water.

To this end, the washing water spraying unit 100 according to the present invention may be configured to include a friction material storage tank 190, and the friction material storage tank 190 is predicted to generate black ice, or black ice is generated, If it is determined that ice has occurred on the road after a snowfall, it can be configured to generate and spray mixed washing water for countering black ice and freezing by supplying a friction material that increases grip to the washing water to prevent accidents by increasing the grip on the road surface. have.

Specifically, the friction material storage tank 190 may be connected to the washing water storage tank 110 by a pipe to supply a friction material to the washing water, and may receive and store a friction material through a separately connected supply pipe, and include aqueous polyurethane as a friction material. It is possible to use a water-soluble friction solution.

Specifically, the aqueous friction solution includes aqueous polyurethane, NMP, and water, and when the aqueous polyurethane is applied to the road surface with a deicing agent, it aggregates with calcium chloride or calcium chloride to form friction material particles, and It not only prevents the generation of black ice and icing by increasing the friction of automobile wheels, but also prevents accidents by reinforcing friction even when black ice and freezing are formed.

Therefore, in order to prevent accidents caused by black ice and freezing on the road, the washing water storage tank 110 receives a friction material from the friction material storage tank 190, and includes both the friction material and the snow removal agent, and water-based polyurethane is uniformly applied to the snow removal agent. The dispersed black ice and mixed washing water for anti-icing may be generated as washing water, and the washing water sprayer may receive and spray the mixed washing water as washing water.

That is, the washing water spraying unit 100 is predicted that black ice or icing will be generated on the road surface by the remote integrated management server unit 600, which will be described later, or when it is determined to be generated, the friction material in the remote integrated management server unit 600 When a control command is transmitted through the communication unit 500 so that the friction material stored in the storage tank can be supplied to the washing water storage tank 110, the friction material stored in the friction material storage tank 190 is supplied to the washing water storage tank, thereby supplying mixed washing water to the road surface. It can be configured to perform snow removal and melting by spraying with washing water.

Therefore, the clean road and snow removal system 10 according to the present invention can spray customized washing water according to the condition of the road, so that it is possible to smoothly perform the snow removal operation along with the response to the washing of the road, black ice or freezing in real time. .

In particular, when black ice is generated or is expected to be generated or when freezing occurs, the mixed washing water is 1 to 20% by weight of an aqueous polyurethane, 0.1 to 20% by weight of a snow removal agent containing 10 to 20% by weight of calcium chloride or magnesium chloride. It can be configured to contain 10% by weight of N-methyl-2-pyrrolidone (NMP) and the rest of the water, and the mixed washing water of this configuration is composed of calcium chloride or magnesium chloride to agglomerate aqueous polyurethane and friction material particles on the road surface. Is formed, thereby reinforcing the gripping force of the vehicle wheel to alleviate the slipping, and to realize the effect of snow removal and melting. Preferably, the mixed snow removal agent may be a mixture containing 15% calcium chloride, 5% by weight aqueous polyurethane, 3% by weight NMP, and 77% by weight water.

Meanwhile, the integrated sensor unit 200 collects environmental information including surface temperature, air temperature, ambient air humidity, and air volume around the road, and generated through the communication unit 500 so that the situation of the snow removal site can be identified online. Video information and temperature data can be transmitted.

To this end, the integrated sensor unit 200 includes a plurality of temperature detection sensors that are respectively installed on the surface of the road and around the road to measure the temperature of the road surface and the air temperature in real time, and measure the air humidity around the road. It includes two humidity detection sensors, and includes a plurality of air volume detection sensors that measure the air volume around the road, so that environmental information including surface temperature, air temperature, ambient air humidity and air volume around the road can be collected, and wired/wireless communication Environment information collected through the communication unit 500 may be transmitted.

Specifically, the temperature sensor enables prediction of the occurrence of black ice caused by moisture, rain, or snow in the atmosphere around the road when the temperature of the road surface is below zero, even when the air temperature around the road is an image. It is equipped to predict the occurrence of black ice caused by rain or snow when the ambient air temperature and surface temperature are below zero.

The humidity sensor is installed around the road surface to measure the humidity around the road, and when the air humidity around the road is high and the temperature of the road surface is below zero, the possibility of black ice generation is high, so the washing water spraying unit 100 is driven. It serves to measure the air humidity so that it can be controlled.

In addition, the air volume sensor measures the air volume around the road, and when the air volume is large, the heat loss of the road surface increases due to the wind, so that cooling of the ground surface can be more easily generated, which is a factor involved in the generation of black ice.

On the other hand, the image acquisition unit 300 generates image information about the situation of the snow removal site, including a plurality of IP cameras installed to photograph the situation of the cleaning or snow removal site of the road, infrared CCTV or visible light CCTV for night work. It is possible to grasp the situation of the road washing site online, and to transmit the image information generated through the communication unit 500 to the remote integrated management server unit 600.

The IP camera, infrared CCTV, or visible light CCTV are respectively installed around the washing water spraying unit 100 installed on the site to photograph the situation of the road, and the situation around the washing water storage tank 110 and the high pressure hose of the washing water spreader 170 Is taken, and the captured image is converted into data and the image information can be transmitted to the remote integrated management server unit 600 through the communication unit 500 online, and accordingly, the manager can view the site situation of the road in real time online. You can check, and you can also check whether it is a snowfall condition with snow or a rainfall condition with rain.

In addition, the clean rod and snow removal system 10 including the image acquisition unit 300 as described above includes both the image information and the radar observing unit 400, and washing water due to an error due to a malfunction of the radar observing unit 400 It is also possible to perform a role of supplementing to drive the operation of the spraying unit 100.

On the other hand, the radar observation unit 400 analyzes the scattering characteristics according to the phase change occurring on the road surface, so that the remote integrated management server unit 600, which will be described later, determines whether black ice or icing has been generated on the road. Radar detection information on the surface may be collected, and meteorological information including rainfall and snowfall may be collected when rainfall or snowfall occurs.

Conventionally, a method of visually checking when freezing occurs on a road surface such as black ice using CCTV or the like is used, but this method has a problem that it is difficult to accurately detect the condition of the road surface. In addition, black ice is affected by road surface temperature, air temperature, air humidity, air flow rate and surface shape, and there is a problem in that it is difficult to accurately determine whether or not freezing due to a transient process of freezing and an inhomogeneous structure, the present invention In, the radar observation unit 400 was introduced to accurately determine black ice and freezing.

To this end, the radar observation unit 400 is connected to the washing water spraying unit 100 through online, and includes a plurality of radar antennas installed around the road where the washing water spraying unit 100 is installed.

Specifically, the radar antenna transmits microwave waves with a wavelength of 1 to 100 GHz in order to analyze the scattering characteristics according to the phase change when there is water, black ice, or freezing (ice) on the road surface, and receives the transmitted radio waves. By measuring the backscatter of the surface, it makes it possible to detect the road surface condition remotely. That is, the radar observing unit 400 determines whether black ice and icing have occurred through a microwave radar back scattering method that collects radar scattering characteristics of the road surface in order to determine whether icing and black ice are generated on the road surface. To collect radar detection information.

The microwave backscatter signal on the road surface generates a backscatter signal due to the surface scattering and volume scattering of the black ice or frozen part of the road, the part with moisture or water, and the scattering of the road itself. When ice is generated or when there is moisture or water on the road surface, different backscatter signals are generated according to changes in the dielectric constant and roughness of the dry road surface, and the radar observation unit 400 generates such a backscatter signal. It collects and enables the remote integrated management server unit 600 to determine whether there is moisture, black ice, or freezing on the road.

When explaining the principle of checking whether black ice and freezing are generated and whether water is present using the radar observation unit 400, a phase change occurs when water is generated on the road surface, or when water is frozen or black ice is generated, This phase change affects the intensity of the radar backscatter signal.

When the radar observation unit 400 irradiates (or transmits) microwaves on the road surface using a radar antenna, radio waves are scattered, the scattered signals are collected, and the collected information is transmitted to the remote integrated management server. The management server unit 600 includes road scattering modeling and inverse modeling information based on an algorithm, and includes environmental information collected by the integrated sensor unit 200, image information collected by the image acquisition unit 300, and a radar observation unit. The presence of water, freezing, and black ice generation can be determined using the scattering intensity signal information collected at (400).

When the radar antenna transmits microwaves to the road surface, a scattering signal divided into surface scattering and volume scattering of ice or water and scattering of the road surface is received, and changes in permittivity and roughness of the surface of ice or black ice due to phase change can be analyzed. have.

Specifically, when water is present on the road surface, a strong surface scattering signal can be collected due to a high dielectric constant of water, and the volume scattering path and the scattering signal on the road surface are very weak due to a decrease in the transmittance of microwaves.

When black ice is generated on the road surface, the intensity of the scattering signal on the black ice surface is weak due to the low permittivity of the road surface, but the intensity of the volume scattering signal and the scattering signal on the road surface increase as the transmittance of microwaves increases. When freezing occurs on the surface, ice crystals are formed on the surface of the frozen ice to increase the surface roughness, and surface scattering is stronger even when the dielectric constant of the frozen ice surface is continuously decreased, and the transmittance of microwaves increases, resulting in volume scattering and road surface. The scattering is also stronger. Accordingly, the remote integrated management server unit 600 may determine whether the presence of water, freezing, or black ice is generated by using the scattered intensity signal scattered through backscatter modeling according to road conditions and inverse scattering modeling using a genetic algorithm.

When black ice is generated on the road surface, the permittivity is 10 to 20, when water is present, the permittivity is 60 to 80, and in the case of dry roads, the surface permittivity is set to less than 5, and the backscattering intensity of the microwave on the road surface is also estimated through dielectric constant estimation. You can model the signal.

Therefore, when the scattering signal information collected by the radar observation unit 400 is transmitted to the remote integrated management server unit 600 through the communication unit 500, the remote integrated management server unit 600 provides environmental information of the integrated sensor unit 200. And video information, when the air temperature around the road is video (above 0 and below 4 °C) or the temperature of the road surface is below zero (-4 to -1 °C), and when the humidity exceeds 60%, or when it rains, it is black. A control command for turning on the driving of the washing water spraying unit 100 by predicting that ice will be generated can be transmitted through the communication unit 500, and the ambient temperature around the road using environmental information and image information of the integrated sensor unit 200 When the temperature of the road surface and the road surface is below zero (−2° C.) and snow falls, a control command for turning on the driving of the washing water spraying unit 100 may be transmitted through the communication unit 500 by predicting that freezing will be generated.

In addition, when it is predicted that black ice will be generated on the road surface, or if it is confirmed that black ice or a frozen point exists, the remote integrated management server unit 600 issues a control command to turn on the driving of the washing water spraying unit 100. It can be transmitted through the communication unit 500, and the driving of the friction material storage tank of the washing water spraying unit 100 is also turned on to supply the friction material to the washing water storage tank, and the mixed washing water can be controlled to be sprayed on the road with the washing water.

In order to observe the road surface using the radar observation unit 400, the radar antenna is installed at a point separated from the road surface in the vertical direction by 1 to 3 m, and 10 m in the vulnerable road area where black ice or freezing occurs frequently. , 20 m, 50 m, 100 m, 200 m, 300 m intervals, a plurality of radar observation units can be installed, and the microwave irradiated from the radar to the road surface can be arranged so that the incident angle is 15° to 60°. , The received microwave scattering intensity signal may be configured to be transmitted to the remote integrated management server unit 600 through the communication unit 500. In addition, the integrated sensor unit 200 and the image acquisition unit 300 may be formed on one side of the radar antenna, respectively.

Furthermore, the radar observing unit 400 can check whether there is snowfall or rainfall by transmitting the microwave of the radar antenna and receiving the strength of the transmitted microwave scattering signal even when it snows or rains around the road. In addition, it is possible to measure the amount of snowfall and rainfall, and by transmitting the corresponding weather information to the remote integrated management server unit 600 through the communication unit 500, it is possible to determine whether there is snowfall, the amount of snowfall or rainfall, and the rainfall on the road in the region. For this reason, it is possible to assist to easily check whether or not there is snowfall even in a situation of rainfall and snowfall that is not visually confirmed by the image acquisition unit 300.

In addition, the remote integrated management server unit 600 controls the driving of the washing water spraying unit 100 to induce suitable road washing, snow removal, and ice melting effects even in different road conditions such as road washing, black ice, freezing, and snowfall. I can.

The remote integrated management server unit 600 uses the environment information, image information, and radar detection information around the road collected by the integrated sensor unit 200, the image acquisition unit 300, and the radar observation unit 400, respectively. When it is determined that the environmental conditions meet the conditions in which black ice is produced, it can be controlled to spray a mixed deicing agent.

Figure 2 is a cross-sectional view showing the structure of the deicing agent storage tank provided in the washing water spraying unit 100 in the clean rod and snow removal system 10 according to an embodiment of the present invention.

2, an example of a container structure provided in a storage tank for washing water, deicing agent or friction material will be described in more detail. The container structure includes a cylindrical body, a through hole formed at the top of the body, and the through hole. It has a structure including a protective cover that is mounted to form a structure that can be opened and closed, and the container structure has a structure in which a plurality of ring-shaped reinforcing protrusions (bumps, B) are formed on the outer wall or inner wall of the main body, and What is made of a polymer material can be used.

The reinforcing protrusion (B) can form a structure to stably reinforce a portion where pressure is concentrated due to the concentration of the stored deicing agent while suppressing the reduction of the container structure and deformation of the cross section as much as possible, and preferably, the When the main body is divided into upper, middle, and lower parts, the lower reinforcing protrusion (B) has the highest protrusion height (h) compared to the middle and upper reinforcing protrusions, and the reinforcing protrusion (B) increases from the bottom to the top. It has a characteristic of lowering the protrusion height. The interval (i) of the reinforcing protrusions may be repeatedly formed by spaced apart by the same length as the vertical length of the reinforcing protrusion in the case of the lower reinforcing protrusion, and the middle reinforcing protrusions are repeated by spaced apart by twice the vertical length of the reinforcing protrusion. It may be formed, and the upper reinforcing protrusion may be repeatedly formed spaced apart by 3 to 4 times the length of the vertical length of the reinforcing protrusion.

The reinforcing protrusion (B) can be formed by fixing to the outer circumferential surface of the storage tank (110, 130, 150) made of the same material as each of the storage tanks (110, 130, 150), thereby increasing the internal temperature It expands and supports the same when expansion pressure is formed inside, and when the external temperature drops, it contracts in the same way as the storage tank, thereby stably supporting the outer circumferential surface of the storage tanks (110, 130, 150). You will be able to do it.

When the container structure (S) having the reinforcing protrusions (B) formed as described above is used as a storage tank, the storage tanks (110, 130, 150) suppress reduction and deformation of the cross section as much as possible, while relatively heavy washing water It is possible to form a structure that stably reinforces the lower part where the pressure is concentrated, so it can prevent the repetition of contraction and expansion due to rapid temperature changes, and the occurrence of cracks caused by the pressure applied by the weight of the washing water. .

Further, each of the container structures (S) may have a structure further including a support structure made of a metal material for fixing and supporting the outer circumferential surfaces of the storage tanks 110, 130, 150, but is not limited thereto.

On the other hand, in the clean rod and snow removal system 10 according to the present invention, the washing water spraying unit 100 is a washing water spreader 170 capable of efficiently performing long-distance spraying of washing water to a road surface or a snow removal site through high pressure pumping.

Specifically, the label bottle part 181 serves to spray the washing water onto the road surface of the cleaning or snow removal site, and may be provided in plural at specific length intervals, and is connected to the supply pipe 173 connected to the washing water storage tank 110 As a result, the washing water stored in the washing water storage tank 110 can be introduced at high pressure.

3 is a view showing a label portion 181 according to an embodiment of the present invention.

3A is an exploded perspective view of the label bottle part 181, (b) is a plan view of the label bottle part 181, (c) is a partial cross-sectional view of the label bottle 182, and (d) is the label bottle part ( 181) is an installation state diagram.

As shown in FIG. 3, the label bottle 181 slides up and down at a position near the four vertices of the label bottle 182 to fix the label bottle 182 and the label bottle 182 to elastically protrude from the road. The fixing bolt 183 is movably coupled, and the cap nut 184 and the fixing bolt 183 are coupled to the top of the fixing bolt 183 to prevent the label bottle 182 from being separated from the fixing bolt 183. A fixing nut 185 that fixes the lower end to the road (A) and an elastic member 186 that is coupled to the outer circumferential surface of the fixing bolt 183 to provide elasticity to elastically move the label bottle 183 in the vertical direction. And an expansion pipe 174 connecting the supply pipe 173 and the label bottle 182 to supply the washing water to the washing water passage 182b formed inside the label bottle 182.

Reflective sheets 182s reflecting light in the lane direction are attached to both side surfaces of the label bottle 182 in a direction along the lane. In addition, a washing water injection port 182a for spraying washing water is formed on a surface facing the inside of the road. At this time, when the marker bottle 182 is installed in the center lane, the washing water injection port 182a is formed on each side of the marker bottle 182 facing the road side, and parking and stopping of the marker bottle 182 forming the side boundary of the road is prohibited. When installed along a line or the like, it may be formed only on the surface of the washing water injection port 182a toward the road side of the label bottle 182. On the contrary, the washing water injection port 182a is formed on each of both sides of the marker bottle 182 facing the road side, and then when the marker bottle 182 is installed along the parking prohibition line forming the side boundary of the road, the road side It may be configured to shield the washing water injection port 182a that is not directed.

The marking bottle part 181 of the above-described configuration allows washing, snow removal, melting ice, and black ice from a remote location by allowing washing water to be sprayed to both sides of the installation door or to one side of the road along the center line or outer boundary lane of the road. Make it possible to perform tasks such as removal.

In addition, as shown in (d) of FIG. 3, the label portion 181 of the above-described configuration is configured to define the lane of the road by the fixing bolt 183, the cap nut 184, the fixing nut 185, and the elastic member 186. By being inserted and installed in the groove in the marked installation position, when the vehicle passes, it is installed so that the position is restored by the elastic member 186 after elastically descending into the groove when the vehicle passes, preventing damage caused by the vehicle. Is configured to

Referring back to FIG. 1, the washing water transfer pipe 175 is connected to communicate with the lower portion of the washing water storage tank 110 to transfer the washing water in the washing water storage tank 110 to the high pressure hose 173, at this time, The washing water passing through the washing water transfer pipe 175 does not flow naturally, but is pumped by the pumping operation of the high-pressure piston pump 180 to be described later. The washing water is pumped from the washing water storage tank 110 to the washing water pumping pipe 177 via the high pressure piston pump 180.

The washing water pumping pipe 177 is connected to the upper portion of the washing water storage tank 110 so as to communicate with the air inlet 117 of the washing water storage tank 110 and communicates with the washing water transfer pipe 175, and the high pressure piston pump 180 The washing water flowing through the washing water transfer pipe 175 is communicated at a high pressure by the pumping operation of and delivered to the high pressure hose 173.

The swing check valve 179 is installed in the washing water pumping pipe 177 corresponding to the upper portion of the washing water storage tank 110, and when the washing water flows above a preset pressure in the washing water pumping pipe 177, it is closed and the washing water pumping pipe ( When the washing water of 177) is transferred to the high pressure hose 173, and the pressure in the washing water pumping pipe 177 is less than a preset pressure, it is opened by atmospheric pressure flowing from the air inlet 117, and high pressure from the washing water pumping pipe 177 Shut off the washing water flowing through the hose 173.

The high-pressure piston pump 180 is connected between the washing water transfer pipe 175 and the washing water pumping pipe 177 and swings as the washing water in the washing water storage tank 110 is pumped to the washing water pumping pipe 177 above a preset pressure. By switching the check valve 179 to a closed state, the washing water of the washing water pumping pipe 177 is transferred to the high pressure hose 173 while the air inlet 117 and the washing water pumping pipe 177 are kept airtight.

On the other hand, the high-pressure piston pump 180 is connected to the driving motor and is configured to perform a pumping operation in connection with the driving force of the driving motor, and to pump the washing water into the washing water pumping pipe 177 at a pressure of ^{20 to 260 kg/cm 2.} By configuring, the washing water stored in the washing water storage tank 110 may be sprayed onto the snow removal site through the label bottle unit 181. At this time, the high pressure hose 173 ^{is made of a synthetic resin material that is flexible to support a breaking pressure of 100 to 300 kg/cm 2} , and a mesh body or iron core woven from a single fiber in the form of a yarn is inserted inside. The washing water can be stably supported even at high pressure to supply the washing water to the label bottle part 181, and the label bottle portion 181 may have a structure in which a washing water injection port having a diameter of 2 to 5 mm is formed in order to spray the washing water.

Therefore, the washing water stored in the washing water storage tank 110 is pumped by the high pressure piston pump 180, so that the washing water passing through the washing water transfer pipe 175, the washing water pumping pipe 177, and the high pressure hose 173 is displayed. It may be sprayed onto the road surface of the cleaning or snow removal site through the washing water injection port of the bottle part 181.

On the other hand, the washing water spreader 170 provided in the washing water spraying unit 100 of the clean rod and snow removal system 10 according to the present invention can supply the washing water at high pressure by opening and closing the swing check valve 179.

4 is an exemplary view showing the opening and closing operation of the swing check valve 179 provided in the washing water spreader 170 of the clean rod and snow removal system 10 according to the present invention.

Referring to FIG. 4, the swing check valve 179 is in a state in which the swing check valve 179 installed at the upper end of the washing water pumping pipe 177 is normally open, as shown in FIG. 4(a), Air through the air inlet 117 may form a structure in which the high pressure hose 173 communicates through the swing check valve 179, and the swing check valve 179 is as shown in FIG. 4(b), When high-pressure snow removal agent flows into the washing water pumping pipe 177 by pumping of the high-pressure piston pump 180, the swing check valve 179 is closed by the hydraulic pressure of the washing water, and the washing water in the washing water pumping pipe 177 is configured to move to the high-pressure hose. can do.

Thereafter, when the operation of the high-pressure piston pump 180 is stopped, the hydraulic pressure flowing to the washing water pumping pipe 177 becomes relatively weaker than the pressure for opening the swing check valve 179 by atmospheric pressure through the air inlet 117. As the hydraulic pressure of the washing water pumping pipe 177 is weakened, the swing check valve 179 is opened again in the state of FIG. 4(a), and then the air through the air inlet 117 is pumped to the high pressure hose 173 and the washing water. By entering the pipe 177, the flow of the washing water connecting the washing water pumping pipe 177 and the high pressure hose 173 is blocked.

Accordingly, the operation of the high-pressure piston pump 180 is stopped and the washing water in the washing water storage tank 110 does not move to the washing water transfer pipe 175. As such, as the operation of the high-pressure piston pump 180 is stopped, the flow of washing water is naturally cut off, so that even if the pumping operation is stopped, the flow of the washing water already formed continues to solve the conventional problem that leakage of the washing water occurred.
