Embodiment Construction
[0016] The anti-icing system of the outdoor ball machine of the present invention includes a control unit, a temperature module and a rotation system. More optimally, it can also include a humidity module and an intelligent analysis module.
[0017] figure 1 It is a flowchart of an embodiment of the present invention.
[0018] When the anti-icing system of the outdoor speed dome is activated, the timer is reset and starts counting.
[0019] The anti-icing system of the outdoor dome camera can start working as soon as the dome machine is powered on, that is, the default state is on. If you don't want it to work, you can turn it off through the switch of the anti-icing system.
[0020] Step 11, cyclically waiting for the timer to time out.
[0021] The timeout time of the timer can be set, and the timeout time can be set according to the ambient temperature.
[0022] Step 12. When the timer expires, the control unit of the anti-icing system judges whether the stationary fla...

The invention provides an anti-icing method for an outdoor dome camera. The method comprises the following steps: A, circularly waiting for the timeout of a timer; B, judging whether a static flag bit of the outdoor dome camera is static or not and whether the current ambient temperature is lower than a freezing point or not when the timer is overtime, executing step C when the static flag bit of the outdoor dome camera is static and the current ambient temperature is lower than the freezing point, and otherwise returning to the step A; C, executing the rotation of the dome camera according to the anti-icing rotation strategy of the outdoor dome camera, setting the static flag bit of the dome camera as rotation, and simultaneously saving the original position of the dome camera before rotating; and D, setting the static flag bit of the dome camera to be static after the rotation of the dome camera, rotating the dome camera to the original position according to the saved original position of the dome camera before rotation, and returning to the step A. Based on the same concept, the invention also provides an anti-icing system for the outdoor dome camera. The anti-icing technology of the dome camera is automatically controlled by the dome camera and is simple and practical, and the cost is low.
Description
technical field [0001] The invention relates to a ball machine in the field of monitoring, in particular to a method and system for preventing freezing of an outdoor ball machine. Background technique [0002] Infrared dome camera is widely used outdoors. It is different from ordinary dome camera in structure. The base part and the pan / tilt part are separated and rigidly connected. It is precisely because of this connection method that the fixed base part and the rotating pan-tilt part are prone to icing under low temperature conditions in winter. Once it freezes, the gimbal control and cruise functions commonly used by the speed dome will be affected or even unavailable. [0003] Aiming at the problem that the infrared ball machine is easy to freeze under the condition of low temperature and high humidity, the existing solution avoids it by improving the structure between the fixed part and the rotating part, such as adding the brim of the hat. There are the following pro...
