Description
Technical Field
The invention relates to the technical field of intelligent control, in particular to an intelligent deicing method and a terminal.
Background
When the video image monitoring equipment is applied outdoors, the problem of icing on the surface of a lens often causes unclear video or shot images, influences the monitoring effect and even can not normally play a role.
In order to solve the problem, in the prior art, a heating device and a temperature sensor are arranged around the lens, and the problems of icing and the like of the lens are avoided by controlling the temperature of the lens within a certain range. However, the power consumption is very high, and the power can be used only by a stable external power supply, so that the power supply is difficult to be applied to a severe environment in which the stable external power supply is inconvenient to obtain; and the heating device is continuously used for a long time, so that the ageing of the heating device and peripheral equipment can be quickened, and the service life of equipment is reduced.
In a further technical scheme, an environment temperature and humidity sensor is additionally arranged outside the equipment, when the environment temperature is lower than a set threshold value and the environment humidity is higher than the set threshold value, the heating device is started again, and if not, the heating device is stopped, so that the service life of the equipment can be prolonged. However, whether the lens is really frozen or not is difficult to judge only through the temperature and the humidity of the environment, the heating device works with a certain blindness and is inflexible, and the power consumption is still too high due to the fact that the heating device is relied on for deicing.
In a further technical scheme, whether the lens is frozen or not is identified through an image analysis algorithm, after the lens is identified to be frozen, the heating device melts the ice coating, and the windscreen wiper removes the ice water, so that normal monitoring work of the equipment is guaranteed. However, the algorithm has higher requirements on the performance of the main control chip, and can increase more cost; and the algorithm has a certain false recognition rate, especially in severe weather.
In addition, the heating device has service life limitation, and the prior art proposal does not fully consider how to protect the heating device, thereby prolonging the service life; in addition, the emphasis of the prior art is that after icing, the icing is removed, but the icing cannot be prevented, so that the equipment cannot work normally for a period of time, and the power consumption is higher; in addition, the prior art scheme is mainly oriented to continuous real-time video equipment, depends on a stable external power supply, and cannot be well applied to periodic video or snapshot equipment such as solar power supply.
