Therefore, the meaning of the terms used in the following embodiments is defined according to the definition when specifically defined in this specification, and unless otherwise defined, it should be interpreted in a sense generally recognized by those skilled in the art.

FIG. 1 is a view illustrating a configuration of an external environment-aware power saving snowmath mat according to an exemplary embodiment of the present invention, FIG. 2 is an exemplary view illustrating a heat- 1 is an explanatory view for explaining the operation timing in the case where the heat generating part is composed of a plurality of heat generating elements among the outside environmentally sensitive power saving snowing mats shown in FIG. Fig.

1, the external environment-aware power saving snow removing mat 100 according to an exemplary embodiment of the present invention includes a body 110, a temperature sensing unit 120, a humidity sensing unit 130, a heating unit 140, And a control unit 150.

The body portion 110 is formed in a flat plate shape of a rubber material. The body 110 may be formed by joining at least one rubber plate, and a heating element may be accommodated therein. It is also possible to include the thermally conductive material of the body 110. It is also possible that the body part 110 is coated with a waterproofing component on its surface for waterproofing. The planar shape of the body 110 may be formed in a rectangular shape, but may be formed in various shapes according to user's setting. It will be apparent to those skilled in the art that the size of the body 110 may vary according to user settings.

The temperature sensing unit 120 senses the surface temperature of the body 110. The temperature sensing unit 120 may sense whether or not ice is formed on the surface of the body 110. It is obvious that the temperature sensing unit 120 can sense the temperature. The temperature sensing unit 120 outputs sensed temperature information to the controller 150 according to a predetermined time period. The temperature information is used as a basis for sensing the temperature change through the control unit 150 and grasping the surrounding environment. For example, when rain or snow falls, it is possible to determine whether it can be iced or snowed depending on the temperature change.

The humidity sensing part 130 senses the surface humidity of the body part 110. The humidity sensing unit 130 senses whether rain or snow contacts the surface of the body 110. [ This is because even if the temperature is low, no freezing occurs unless rain or snow falls. The humidity sensor 130 outputs the sensed humidity information to the controller 150 according to a predetermined time period. The humidity information is a basis for grasping the surrounding environment through the humidity change through the control unit 150. For example, when the humidity is rapidly increased, rain or snow falls, and when the humidity is gradually decreased, it can be recognized that the rain or snow is stopped.

The heat generating unit 140 is formed of a resistor material and generates heat when power is supplied from an external power source or an internal power source (not shown). In this case, the heat generating unit 140 may be a surface heating element having a positive temperature coefficient (PTC) or a negative temperature coefficient (NTC) component, but is not limited thereto. The heating unit 140 may be formed of a plurality of heating elements and may output different amounts of heat. In addition, when the heat generating unit 140 is formed of a plurality of heat generating bodies, it is also possible to heat only a part of the heat generating bodies. It is preferable that the operation of the heat generating unit 140 is controlled to minimize the power consumption while minimizing the ice phenomenon on the surface of the body 110.

The control unit 150 drives the heat generating unit 140 using the surface temperature and the surface humidity. For example, by sensing the surface temperature and the surface humidity, the heating unit 140 is driven in the preheat mode of the first temperature range when the eye is expected. Here, the first temperature range means the minimum heat generation temperature set by the user. This is to heat the surface of the body part 110 in advance to allow the snow to melt immediately before the snow falls.

The control unit 150 may drive the heating unit 140 in a snowmelt mode of the second temperature range when the snow on the surface of the body 110 is snowed. Here, the second temperature range means a high temperature range that does not overlap with the first temperature range. This is to dissolve snow or ice when snow is frozen by increasing the heat quickly to prevent slip accidents.

In addition, the control unit 150 can control to stop the driving of the heat generating unit 140 when the snow does not fall. This is because it is unnecessary to operate in the preheating mode or the snowing mode in the case where the rain or snow does not fall, so that the power consumption by the heat generating unit 140 is minimized. The control unit 150 can detect the temperature change and the humidity change according to a predetermined time period and control the on / off timing of the heat generating unit 140. When the temperature change and the humidity change occur even in the standby mode in which the heat generating unit 140 is not driven, the heat generating unit 140 can be driven in the preheating mode or the snowing mode.

Meanwhile, the external environment-aware power saving snow removing mat 100 according to an embodiment of the present invention may further include a communication unit 160. The communication unit 160 communicates with an external communication device 200 to transmit temperature information, humidity information, and consumption power information of the power saving snowmelt 100 to the outside, Forecast information, and the like. The communication unit 160 is capable of network communication and can be both near-distance and remote communication.

In this case, the control unit 150 can receive the weather forecast information of the location where the power saving snow mats 100 are located from the external communication device 200 through the communication unit 160. The control unit 150 may adjust the calorific value of the heat generating unit 140 differently according to the weather forecast information changing according to the predetermined time interval. In this case, the heat generating unit 140 can operate in any one of the preheating mode, the snow removing mode, and the standby mode.

The control unit 150 may correct the error of the calorific value by comparing the surface temperature information and the surface humidity information of the body 110 with the weather forecast information through the temperature sensing unit 120 and the humidity sensing unit 130. For example, rain or snow may be expected to fall through the surface temperature information and the surface humidity information of the body portion 110. However, in case of forecasting that the rain or snow will not fall, the weather forecast information is weighted on either side Select two operation modes. Here, the reliability is determined based on a predetermined time interval, and the heat generating unit 140 is driven on the basis of information having a high reliability by weighting a higher probability.

Meanwhile, the external environmentally sensitive power saving snow removing mat 100 according to an embodiment of the present invention may further include a pressure sensing unit 170. The pressure sensing unit 170 senses the surface pressure of the body 110 and outputs pressure information to the controller 150. The pressure sensing part 170 may be implemented using a piezoelectric element and senses the movement of vehicles or people passing through the surface of the power saving snow mats 100. This pressure information is used to differentiate the heat generation amount because snow tends to be crowded due to the load of a vehicle or a person when the snow falls on the surface of the body part 110. [

In this case, when the surface of the body part 110 is pressed from the pressure sensing part 170 to a predetermined pressure or more during the operation of operating the heat generating part 140 in the snow removing mode, It is possible to drive the heat generating unit 140 in the concentrated mode in the temperature range of 3 degrees. In this case, the heat generating unit 140 may be composed of a plurality of spaced apart heat generating bodies. The calorific value of each heating element can be set differently depending on the sensed pressure difference. For example, when the surface of the body 110 is set to be 2 ° C in the snow removal mode, the amount of heat generated by the heating element at the corresponding position can be increased so that the surface of the body 110 is 5 ° C in the concentrated mode. As a result, it is possible to effectively melt ice at the frozen position.

2 and 3, the heating unit 140 of the external environmentally sensitive power saving snow removing mat 100 according to the embodiment of the present invention includes a first heating element 141 and a second heating element 142. Here, the first heating element 141 and the second heating element 142 are used to distinguish heating elements operating to have different power consumption, and the third heating element 143 or more heating elements may be added It is possible. The heating unit 140 measures the power consumption of each heating element and outputs the measured power to the controller 150.

The control unit 150 generates a first control signal which is an operation signal of the first heating element 141 and generates a second control signal which is an operation signal of the second heating element 142, 141 and the second heat generating element 142 to operate at a maximum power or less. This is to not divide the first heating element 141 and the second heating element 142 at all times but divide the power within the maximum power range by selectively controlling the time division. The first heating element 141 and the second heating element 142 can maintain the surface temperature of the body part 110 according to the predetermined heating value without exceeding the total maximum power by changing the operation timing.

When the consumed electric power of the first heat generating element 141 and the second heat generating element 142 is equal to or lower than the maximum power when the second heat generating element 142 is operated during the operation of the first heat generating element 141, If the maximum power is exceeded, the second heating element 142 is operated while reducing the operation period of the first heating element 141 so that the consumed electric power of the first heating element 141 and the second heating element 142 is less than the maximum electric power .

3 shows the operation timings of the first heating element 141, the second heating element 142 and the third heating element 143. In this case, the maximum power of the power saving snow mattress 100 (operation time 100% ) Are respectively 1100 W, 1650 W and 2000 W, the operation period is 1 minute, and the power tolerance is 3.3 kW.

When the third cycle (cycle 3) is compared, the operation of the first heating element 141 is temporarily stopped while the second heating element 142 is turned on and starts its operation. The first heating element 141 is turned on during the period in which the second heating element 142 is periodically turned off so that the simultaneous operation period is set to zero to reduce the instantaneous power consumption to the minimum have.

On the other hand, when a simultaneous operation section is inevitably generated when three or more heating elements operate (more than 0 seconds), a combination in which the sum of consumed power of at least two or more heaters among at least three heaters is the minimum, To control the timing of each heating element.

In other words, when the fifth and sixth cycles (cycle 5) are compared, the third heat generating element 143 is operated at a consumed electric power of 50%, that is, As shown in FIG. The sum of the consumed electric power of the first heating element 141 and the second heating element 142 is 2750 W and the sum of the consumed electric power of the second heating element 142 and the third heating element 143 is 3650 W, Since the sum of the consumed electric power of the first heat generating element 141 is 3100 W, the operation start timing is controlled so that the first heat generating element 141 and the second heat generating element 142, which have the smallest sum of consumed power, do. Therefore, when the start timing is adjusted so that the first heating element 141 and the second heating element 142 have a simultaneous operation period apart from the operation time of the third heating element 143, The power consumption is stable at 2750 W for 30 seconds and 2000 W for 30 seconds thereafter.

Referring to FIG. 4, the external environmentally sensitive power saving snow removing mat 100 according to the embodiment of the present invention may further include a drying unit 180. The drying unit 180 is formed on one side of the upper portion of the body 110 to emit wind of predetermined wind force. In this case, the wind discharged from the drying unit 180 can be operated in the cold wind drying mode or the hot wind drying mode.

In this case, the control unit 150 may stop the operation of the heat generating unit 140 when it is determined that the temperature of the body 110 is lowered through the temperature sensing sensor, the humidity sensing sensor, or the communication unit 160. Thereafter, when the rain has stopped, the drying unit 180 can be driven. This is to quickly remove rainwater on the surface of the body 110 after the rain has stopped.

The control unit 150 may also drive the heat generating unit 140 in the preheat mode when the temperature of the surface of the body 110 is low when the temperature is low. This is to prevent rainwater from freezing after the rain stops. In this case, the heat generating unit 140 and the drying unit 180 may be simultaneously driven to improve the drying speed.

Meanwhile, the external environment-aware power saving snow removing mat 100 according to the embodiment of the present invention may further include an alarm unit 190. [ The alarm unit 190 may output predetermined sound and sound. When the surface of the body part 110 is frozen, the alarm part 190 outputs a warning sound to a person walking on the body part 110 to prevent slipping. It is also possible to warn the user when a fire occurs due to overheating of the body 110.

In this case, the heating unit 140 may sense the overcurrent of the power source supplied to the body 110. This is to detect in advance the risk of fire when an overcurrent is supplied to the heating unit 140 from an external power source. Since the power saving snow mats 100 are mostly located outdoors, they sense the situation that the overcurrent protection circuit does not operate due to performance deterioration, and output the detected state to the control unit 150. [

In this case, the control unit 150 may operate the alarm unit 190 when the surface temperature of the body 110 rises above a preset temperature or an overcurrent is detected through the heat generating unit 140. The control unit 150 may output a warning sound through the alarm unit 190 when the surface of the body 110 is frozen. As a result, the risk of fire or the risk of freezing can be communicated to people nearby.

Meanwhile, the external environment-aware power saving snow removing mat 100 according to the embodiment of the present invention may further include an image obtaining unit 191. [ The image acquiring unit 191 can transmit an image around the power saving snow mats 100 to the external communication device 200 through the communication unit 160. [ This is to allow a remote user to visually check the state of icing.

The image acquiring unit 191 may capture the surface of the body 110 and output the image to the controller 150. The control unit 150 analyzes the surface vision image of the body 110 obtained from the image acquiring unit 191 to determine whether or not it is freezing. In this case, the vision image may be a previously processed image, and it may be determined whether or not the ice is frozen by analyzing pixel values of the frozen area and the non-frozen area. Accordingly, it is possible to judge whether or not the surface is frozen through the surface image separately from the surface temperature and the surface humidity, thereby improving the accuracy. When the heating unit 140 is in the preheating mode or the standby mode, the control unit 150 can drive the heating unit 140 in the heating mode or the concentrated mode if the ice is confirmed by the surface image.

Meanwhile, the external environment-aware power saving snow removing mat 100 according to the embodiment of the present invention may further include a fire extinguisher 192. The extinguishers 192 may be formed in a powder form and formed between a plurality of exothermic bodies. The fire extinguishing unit 192 serves to prevent the fire early due to the fire extinguishing powder when the body 110 generates a fire due to overheating. The arrangement of the fire extinguishers 192 may vary depending on user settings. In this case, the extinguishing unit 192 may be packaged and arranged by a capsule or plastic that melts at a predetermined temperature.

Meanwhile, the external environment-aware power saving snow removing mat 100 according to the embodiment of the present invention may further include a power generating unit 193. The power generation section 193 can be implemented using a solar cell or a piezoelectric element.
