Embodiment Construction

[0035] The technical scheme of the present invention is described in further detail below:

[0036] A camera defogging system, comprising an optical transmitter, an optical receiver, a photoelectric conversion module, a filtering module, a control module, a heating module and a fan;

[0037] The light emitter is used to emit light at a constant intensity to the inner wall of the camera window glass;

[0038] The light receiver is used to receive the light reflected by the inner wall of the camera window glass after being emitted by the light transmitter;

[0039] The photoelectric conversion module is used to convert the optical signal received by the optical receiver into an electrical signal;

[0040] The filtering module is used to filter the electrical signal converted by the photoelectric conversion module, and transmit the filtered electrical signal to the control module;

[0041] The heating module is used to heat the air near the window glass of the camera;

Abstract

The invention discloses a defogging system for a camera. The defogging system for the camera comprises a light emitter, a light receiver, a photoelectric converting module, a filter module, a control module, a heating module and a fan; the light emitter is used for emitting light to the inner wall of window glass of the camera at a constant intensity; the light receiver is used for receiving the light emitted by the light emitter and reflected by the inner wall of the window glass of the camera; the photoelectric converting module is used for converting a light signal received by the light receiver into an electrical signal; the filter module is used for filtering the converted electrical signal; the heating module is used for heating air close to the window glass of the camera; the fan is used for blowing the heated to the window glass of the camera; the control module is used for comparing the strength of the received electrical signal with the preset intensity threshold, and controlling the heating module and the fan to work or not work according to the comparing result from the comparing unit. With the adoption of the defogging system for the camera, whether the window glass of the camera is fogged can be intelligently determined; in addition, the fog can be automatically removed in case of fogging.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a camera defogging system. Background technique [0002] A video camera is a machine that converts optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected on the object is collected by the camera lens, making it focus on the light-receiving surface of the imaging device (such as the target surface of the imaging tube), and then the light is converted into electrical energy by the imaging device, that is, "Video Signal". The photoelectric signal is very weak and needs to be amplified by a pre-amplification circuit, and then processed and adjusted by various circuits. The final standard signal can be sent to a recording medium such as a video recorder for recording, or transmitted through a communication system or sent to a monitor. display. [0003] Just like cameras, early cameras needed to use negatives (that is, video tap...
