Abstract

The invention discloses a method, system, and apparatus for preventing restarting of an infrared camera. The method comprises: a power supply voltage of an infrared camera is detected; whether the power supply voltage is larger than a lower limit value of a stable value zone is determined; if the power supply voltage is larger than the lower limit value of the stable value zone, an equivalent voltage of pulse width modulation is adjusted according to a first preset rule until the brightness of an infrared lamp included by an infrared lamp panel reaches a maximum value, wherein the equivalent voltage is used for controlling the brightness of the infrared lamp; and if the power supply voltage is smaller than or equal to the lower limit value of the stable value zone, the equivalent voltage of pulse width modulation is adjusted according to a second preset rule, so that the brightness of the infrared lamp included by the infrared lamp panel is reduced. Therefore, a problem of how to prevent restarting of an infrared camera effectively in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method, system and device for preventing an infrared camera from restarting. Background technique [0002] At present, because the long-distance power supply cables of infrared cameras are generally long, the infrared lights need to be turned on when the infrared cameras work at night. When the infrared lights are turned on, the current becomes large and the voltage drop on the power cable is too large. As a result, the power supply voltage of the infrared camera is insufficient, which will cause the infrared camera to restart. [0003] In order to solve the restart problem caused by the long-distance power supply of the infrared camera, in related technologies, high and low levels are generally used to directly control the turning on and off of some infrared lights. However, this control method is simple, there is no feedback control for the control of the infrared lamp, and t...
