Embodiment
Referring to figs. 1 through Fig. 3, the utility model portable boat-carrying integrated optical electricity night vision device embodiment of cruising is described further.
As shown in Figure 1, a kind of portable boat-carrying integrated optical electricity cruises night vision device, comprise night vision cam 1, searchlight source 2 and supporting seat 3, supporting seat 3 is "T"-shaped, night vision cam 1, searchlight source 2 are arranged at the both sides of supporting seat 3 respectively, and night vision cam 1 and searchlight source 2 all can freely be rotated on supporting seat 3, all realize in existing monitoring camera-shooting technology, this is part total in prior art, does not repeat them here.The top of supporting seat 3 is provided with light sensor A1, light sensor A1 is the top being fixed on supporting seat 3, so just directly can sense extraneous light conditions, described light sensor A1 is in order to detect intensity of illumination and output detection signal, described light sensor A1 is connected with control circuit A2, and described control circuit A2 is in order to receive detection signal and to control the break-make of the power supply in searchlight source 2.Cruise by adopting night vision cam 1 to monitor, improve the readability of night surveillance picture, configure the definition that picture is improved in searchlight source 2 further simultaneously, light sensor A1 is used to respond to light luminance degree in daytime and night, when ambient light deficiency, light sensor A1 can detect, output detection signal, light is stronger, detection signal stronger, light is more weak, detection signal is more weak, therefore, detection signal is received by control circuit A2, the power supply simultaneously controlling searchlight source 2 is switched on or switched off, searchlight source 2 is made to there is no need to open in well-lighted situation, waste electric energy, thus can automatically control its closedown by control circuit A2, and when insufficient light, when needing searchlight source 2 to carry out auxiliary, just connect the power supply in searchlight source 2, make its work, thus reach energy-conservation effect, improve the convenience of use simultaneously, the work in automatic control searchlight source 2.
