Technical Field
The utility model relates to a supervisory equipment technical field, concretely relates to supervisory equipment camera glass defogging device.
Background
The generation of fog is a ubiquitous phenomenon in nature. When high-temperature and high-humidity air contacts a low-temperature interface (such as glass and plastic), and the low-temperature interface has small protrusions or dust and the like which can be used as condensation cores, water vapor can be condensed into salt water drops, and if the dew point temperature is higher than zero centigrade, the fogging phenomenon is formed. In winter, fog usually appears on a camera lens of the monitoring equipment, so that a shot image becomes very fuzzy, and the camera cannot work normally.
The above problems are problems that the art needs to solve.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a supervisory equipment camera glass defogging device to can clear away the fog on the camera glass, make the camera can normally work.
In order to solve the technical problem, the utility model provides a scheme is: the utility model provides a supervisory equipment camera glass defogging device, includes the camera, the camera front end is provided with window glass, window glass surface is located the outer lane and is provided with the heating plate, window glass one side is provided with temperature and humidity sensor.
As a further improvement, the window glass is provided with a fixing plate outside the heating plate, and the fixing plate is provided with a thermistor.
As a further improvement, the thermal insulation ring is sleeved outside the thermistor, and the contact surface of the thermistor and the fixed plate is provided with heat-conducting silica gel.
As a further improvement of the utility model, the window glass is electric heating glass.
As a further improvement, the temperature and humidity sensor, the thermistor with the heating plate is all connected and is provided with the control unit, the control unit includes singlechip and electronic switch.
The utility model has the advantages that:
the utility model has the advantages of reasonable and simple structure, the simple operation, temperature and humidity sensor detect near window glass's air temperature Ta and relative humidity Rh, carry out the comparison with the temperature Tg of glass window itself, and then judge whether window glass satisfies the temperature condition of hazing, if satisfy the condition, then the heating plate begins work, heats window glass, can clear away the fog on the window glass. Meanwhile, the air temperature Ta, the relative humidity Rh and the temperature Tg can be combined for comprehensive judgment, when the risk of fogging is high, the heating sheet is started to heat, and when the risk is reduced, the heating is stopped. Therefore, the fog on the camera glass can be removed, and the camera can work normally.

Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1, for the utility model discloses an embodiment, including camera 1, camera 1 front end is provided with window glass 2, window glass 2 surface is located the outer lane and is provided with heating plate 3, can avoid sheltering from to the camera, make it can normally work, window glass 2 one side is provided with temperature and humidity sensor 4, install temperature and humidity sensor 4 as far as possible near window glass 2 simultaneously, avoid camera 1 operating temperature to cause the influence to it, temperature and humidity sensor 4 detects near window glass 2's air temperature Ta and relative humidity Rh, compare with the temperature Tg of glass window 2 itself, and then judge whether window glass 2 satisfies the temperature condition of hazing, if satisfy the condition, then heating plate 3 begins to work, heat window glass 2, can clear away the fog on the window glass 2. Meanwhile, the air temperature Ta, the relative humidity Rh and the temperature Tg can be combined for comprehensive judgment, when the risk of fogging is high, the heating sheet 3 is started to heat, and when the risk is reduced, the heating is stopped. Meanwhile, the heating time of the heating plate 3 is limited, so that the window glass 2 is heated after the fog is removed.
In this embodiment, in order to detect the temperature Tg of the window glass 2 itself, a fixing plate 5 is provided on the window glass 2 outside the heating sheet 3, and a thermistor 6 is provided on the fixing plate 5. When the camera is installed, the fixing plate 5 can be embedded in the protective cover of the camera 1, and meanwhile, the thermistor 6 needs to be far away from the heating sheet 3, so that the temperature of the heating sheet 3 is prevented from influencing the fixing plate, and the temperature Tg of the window glass 2 can be detected through the thermistor 6.
In this embodiment, in order to improve the temperature transmission effect of the window glass 2, the thermal insulation ring 7 is sleeved outside the thermistor 6, and the contact surface between the thermistor 6 and the fixing plate 5 is provided with heat-conducting silica gel, so that the temperature transmission effect can be improved.
In this embodiment, window glass 2 can also be electrical heating glass, and electrical heating glass's light transmissivity can not influence camera 1 and normally use for window glass 2 just can heat in the past, thereby can get rid of the surperficial fog.
In this embodiment, in order to realize its automated control, temperature and humidity sensor 4, thermistor 6 and heating plate 3 all connect and are provided with the control unit, and the control unit includes singlechip and electronic switch, and the control unit detects and gathers temperature and humidity sensor 4, thermistor 6's information, and electronic switch controls the on-off state of heating plate 3.
During actual work, the temperature and humidity sensor 4 detects the air temperature Ta and the relative humidity Rh near the window glass 2 in real time, the control unit calculates the dew point Td, the thermistor 6 detects the temperature Tg of the glass window 2 in real time, meanwhile, the control unit compares the dew point Td with the temperature Tg, and when the risk of fogging is judged to exist, the electronic switch controls the heating sheet 3 to start heating for a period of time so as to reduce the risk of fogging; when the fogging condition is judged to be satisfied, the electronic switch controls the heating sheet 3 to start heating, and when the heating is performed until the fogging condition is not satisfied, the heating is stopped. Therefore, the fog on the camera glass can be removed, and the camera can work normally.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitution or transformation made by the technical personnel in the technical field on the basis of the utility model is within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
