    Hereinafter, the moisture and the road surface temperature which are factors of the road surface freezing will be described.

    In order to generate freezing on the road surface, water temperature below freezing point and water is required, and water is frozen by dropping below freezing point, which is directly affected by road temperature.

    Water present on the road surface is freezing point due to the influence of the temperature of the outside air (in the present invention, the term outside air to describe the concept of the outside atmospheric temperature of water in terms of the moisture temperature) and the road surface temperature.點) It must fall down to freeze from its surface. The road temperature will directly affect the moisture temperature rather than the outside temperature, and the influence of the outside temperature on the moisture temperature will depend on the strength of the wind.

    Even if the temperature of the outside air is below the freezing point and the road surface temperature is also below the freezing point, freezing will not occur unless the temperature of the moisture reaches the freezing point. However, when the temperature of the outside air is below the freezing point and the road surface temperature is also below the freezing point, it may be an extremely unusual example that the moisture on the road surface does not freeze by maintaining a temperature higher than the freezing point.

    And of course, as mentioned above, even if the temperature of the road surface as well as the temperature of the road surface is below the freezing point, there will be no freezing if there is no moisture on the road surface.

    Therefore, in order for freezing to occur on the road surface, there must be moisture on the road surface and the water temperature on the road surface must be below freezing point, and in order to drop the temperature of water below freezing point in order to drop below the freezing point. There must be conditions such as road temperature below freezing point.

    In the case of snowfall, snow will snow on the road surface and generate freezing according to the outside temperature, but the rate of freezing will be low when the amount of snowfall is low and the road surface temperature and the outside air temperature are high.

Hereinafter, the relationship between the outside temperature and the road surface temperature will be described for reference.

The road temperature and the outside air temperature at 1.5m height from the road surface has a significant temperature difference as shown in Table 1 below, and it can be seen that the temperature difference is greater in the night time zone than the day time in the bridge section. (Night: △ 6.2 ° C, Day: △ 4.2 ° C)

Relationship between the road surface and the height of 1.5m

Measurement date and wind speed: 2009.02.02. 16: 00 ~ 24: 00, 0.9m / s

In addition, the above temperature difference also results in freezing rain, which freezes as it rains on the road when the temperature is between -3 ° C and 2 ° C. To prevent this, an unscrupulous warning or an unscrupulous alarm is issued.

As described above, the moisture and the temperature causing the road freezing also indicate that the outside air temperature is a factor of freezing and the road surface temperature is more directly and significantly affecting freezing.

Existing manual thawing liquid spraying device always checks temperature, humidity, etc., and the manager moves directly to operate it manually, causing a lot of manpower and time delays. There is a problem that it is difficult to deal with urgently.

In addition, the thawing liquid unmanned spreading device collects, analyzes, and processes weather information on a road in a specific section, compares it with a reference value, and transmits and operates the unmanned spray device installed in the road in the corresponding section. This unmanned spreading device has advantages such as manpower saving, time reduction, and urgent and quick response capability, unlike manual method in which the manager operates the spraying device on site according to the collected and analyzed weather information.

However, the unmanned spraying device has the following problems, which is also a problem to be solved in the present invention.

Existing sea ice-liquid spraying device collects, analyzes, and processes meteorological information such as air temperature on roads collected from roads in a certain section, and determines whether or not sea ice-liquid is sprayed by comparing it with reference values. Therefore, the range of operation error was large by controlling the spreading device based on a wide range of weather information different from the real-time weather information of roads installed in a short section (about 200 to 500m).

Looking at this in more detail; Existing unmanned spreading device analyzes and predicts a wide range of information collected from a specific area or a specific section in the central control system, and determines whether the spreading device is operating based on this. It was to reduce the stable operation and effectiveness of the spreading equipment.

In particular, as shown in Table 1, the unmanned spraying device operated by the above-described conventional method has many operating errors in the section where the variable of the road surface freezing, ie, the freezing factor, is high and vulnerable as shown in Table 1 above. .

In addition, many existing unmanned spraying devices described in the above description detect and collect weather information such as road temperature and moisture from the road surface and control the operation of the spraying device. There is no specific reference to how and through which information is collected and how it is linked to the operation of the spreading device, and no clear solution has been given.

In the present invention, by installing the water sensor to detect the moisture installed on the road to control the operation of the spraying device through this to determine whether the freezing conditions by the moisture and road surface temperature that is the factor of freezing on the road operation of the spraying device It is to determine the presence of the operation of the spreading device.

Hereinafter, the specific contents for the implementation of the present invention will be described in detail.

1 is an overall schematic view of the present invention, Figure 2 is a perspective view showing an embodiment of the icing factor detector of the present invention, Figure 3 is a partially separated perspective view of Figure 2, Figures 4, 5 is a cross-sectional view of FIG.

The thawing liquid spreading device A is connected to the thawing liquid, the thawing liquid storage tank A1, the pump A2, the pump A2 and embedded in the road as shown in FIG. 1, the control panel A3, etc. Such a sea ice-liquid spreading device (A) is generally composed of.

The present invention comprises a moisture detector (1) for detecting the presence or absence of moisture that causes the road surface freezing and the temperature of the road surface in the above-mentioned sea ice liquid spraying device, by using the water sensor (1) ) Is working.

Moisture sensor 1 is made of the same material as the road in order to detect moisture detection and road surface temperature under the same conditions as the road on which the sea ice spraying device A is installed. The presence sensor (3) is installed and comprises a temperature sensor (4).

The road sampling 2 is preferably formed of a rectangular parallelepiped or the like of the same material as the road so as to have the same conditions as the road.

The road surface sampling (2) is coupled to the fixing plate (5) and the fixing plate (5) is fixed to the roadside barriers, such as anchor bolts can be installed on the roadside, such as a water ice detector (A) is installed moisture detector (A). To be. To this end, the fixing plate 5 forms a flange 51 so as to couple the anchor bolt.

The upper side of the fixing plate (5) and the side plate (6, 6 ') and the upper plate (7) is configured in the form of a box and combines the road surface sampling (2) to be received therein.

Side plates 6 and 6 'are provided with ventilation holes 61 for matching conditions such as roads.

The moisture presence sensor 3 forms a conductive space 31 so that electricity is conducted through the medium in accordance with the presence of moisture in the conductive space 31 so as to sense the presence or absence of the moisture according to the flow of current. Configure.

The conductive space 31 is formed to have a variable area between the positive electrode plates 32 and 32 'provided on the surface sampling 2 surface and falls in the conductive space 31 between the positive electrode plates 32 and 32'. When water, such as rain or snow, is introduced, electricity is transferred to the medium to detect the presence of water. The positive electrode plates 32 and 32 'are always supplied with a current required for moisture detection, and the current supplied to the positive electrode plates 32 and 32' is supplied with moisture depending on the area of the conductive space 31. As long as the current is conductive and can be detected.

The positive electrode plates 32 and 32 ′ forming the conductive space 31 are disposed on an upper surface of the road surface sampling 2. That is, the positive electrode plates 32 and 32 'are disposed on both sides between the surface sampling surface 2 and the upper plate 7 and the positive electrode plates 32 and 32' are fastened by the upper plate 7. 8, 8 ') to vary the gap between the positive electrode plates 32 and 32' so that the size of the conductive space 31 formed between the positive electrode plates 32 and 32 'can be adjusted. do.

An inlet 71 is formed in the upper plate 7 to allow rain and snow to flow into the conductive space 31 formed by the positive electrode plates 32 and 32 ′, and water in the conductive space 31 is formed at one side thereof. The drain hole 72 is formed so that it can be discharged. The inlet 71 is formed to have a size enough to allow a rain, snow, or the like to flow into the conductive space 31 between the two electrode plates 32 and 32 ′.

The upper plate 7 is naturally formed to be movable when the gap between the two electrode plates 32 and 32 'is adjusted. In the example shown, the slide grooves 73 of the electrode plates 32 and 32' are formed. The case is illustrated.

The fixing plate 5 and the side plates (6, 6 '), the upper plate (7) can be configured to be assembled as an assembly bolt (10).

On the other hand, the road surface sampling (2) coupled to the temperature sensor (4) to detect the road surface temperature, the temperature sensor (4) is buried in the upper surface of the road sampling (2) to contact with moisture It would be desirable to detect a temperature close to the surface of the road surface.

The moisture presence sensor (3) and the temperature sensor (4) is connected to the control panel (A3) of the sea ice-liquid spreading device (A) by wire or wireless communication through a circuit board of one side control box (9). In addition, the moisture presence sensor (3) flows between the positive electrode plates (32,32 ') by connecting the resistance value detection means for detecting the resistance value of the current flowing between the two electrode plates (32,32'). When the current flows through the moisture, the resistance value of the current is detected and the amount of moisture is detected by the resistance value, thereby determining whether the thaw liquid spreading device (A) is operated.

Adjusting the distance between the two electrode plates (32, 32 ') and detecting the resistance value in the above is related to the installation environment of the thawing liquid spreading device (A). The road on which the sea ice spraying device (A) is installed may be an area in which the sun does not receive any sunlight until sunrise or sunset depending on the environmental characteristics of the area, or vice versa. This can be variously discriminated in this way, in consideration of the geographical and environmental impact, such as the sea ice liquid spraying device (A) is installed to adjust the moisture detection amount of the moisture sensor (1).

For example, the distance between the two electrode plates 32 and 32 'is reduced to reduce the amount of moisture detected on roads where the sun is hard to reach due to the geographic environment and the road surface freezes easily due to relatively small rainfall or snowfall. By narrowing the amount of water to be detected, on the other hand, in the area where road freezing does not occur easily during snowfall, the water detectors can be detected by increasing the distance between the two electrode plates 32 and 32 'to detect a relatively high amount of water. The amount of moisture that can be detected by (1) can be adjusted and used according to various situations.

The amount of moisture detected will be described again through a relationship with a resistance value, a road surface temperature, and the like, which will be described later.

The positive electrode plates 32 and 32 'check the amount of moisture as resistance values detected between the positive electrode plates 32 and 32' as well as control the amount of moisture detected by the spacing and spread the device according to the road surface temperature described below. Determine the amount of sea ice solution spread and the spread time.

The moisture flowing into the conductive space 31 of the positive electrode plates 32 and 32 'may be detected differently according to the amount of resistance of the current flowing between the positive electrode plates 32 and 32'. The detected road surface temperature from the temperature sensor 4 is checked by checking the amount of moisture for the operation of the spraying device A together with the amount of moisture detected by the gap between the two electrode plates 32 and 32 '. In addition, it is determined whether the sea ice-liquid spreading device (A) is operated.

On the other hand, Figure 6 is a perspective view showing another embodiment of the present invention, Figure 7 is a partially separated perspective view of Figure 6, the appearance of the moisture sensor 1 is configured differently from the above-described embodiment as shown in Figs. The temperature / humidity sensor 11 which can detect the temperature and humidity of air | atmosphere) is attached.

As shown in FIGS. 6 and 7, the conductive space 31a of the moisture presence sensor 3 can be more secured to detect presence or absence of water with a large sensing area, and can detect outside temperature and humidity. Equipped with a temperature and humidity sensor 11 through the information of temperature and humidity collected from them to contribute to a more accurate ice prediction.

In addition, by embedding the cable tube 12 for wiring such as cables inside the road surface sampling (2a) it is possible to achieve a clean and stable wiring.

The moisture sensor 1 configured as described above operates the spraying device A by detecting the presence of water and the road surface temperature through a road surface sampling 2 made of the same material as the road surface of the road on which the sea ice spraying device A is installed. . When the moisture sensor 1 detects moisture from the moisture presence sensor 3 and detects that the road surface temperature is below the freezing point from the temperature sensor 4, the freezing conditions of the presence of water and the road surface temperature are satisfied, and thus, The spreading device is operated by transmitting a detection signal to the control panel. If both the presence of water on the road and the road surface temperature do not meet the freezing conditions, the sea ice spreader (A) will not operate, and if both of them meet the freezing conditions, the sea ice spreader (A) Will work.

That is, when moisture such as rain is detected from the moisture presence sensor 3 and the road surface temperature above the freezing point is detected from the temperature sensor 4, and even if the temperature below the freezing point is detected from the temperature sensor 4, the moisture presence sensor If no moisture such as rain is detected from (3), the thaw spreading device A will not operate, and the thaw spreading device A will operate when these freezing conditions are met.

Therefore, in the present invention, the moisture detector 1 actively and closely responds to climate conditions fluctuating in real time in river crossing bridges, etc. and detects water and road surface temperature required for freezing conditions in real time to operate the sea ice liquid spraying device A. By determining whether or not to improve the emergency response capacity of the sea ice-liquid spreading device (A) as well as can significantly reduce the error occurrence rate. Hereinafter, the operation method of the sea ice-liquid spreading device A using the moisture sensor 1 will be described as follows. The operating method of the sea ice-liquid spreading device (A) using the moisture sensor 1 is made of a relatively simple process.

The operating method of the sea ice-liquid spreading device (A) using the moisture sensor 1 according to the present invention is as follows.
