Description of drawings
The structural representation of two CCD supervisory control systems of a kind of embodiment of Fig. 1 the utility model.
Feature of the present utility model and advantage will further specify in conjunction with the accompanying drawings by embodiment.
Embodiment
Please refer to Fig. 1, two CCD supervisory control systems of a kind of embodiment comprise two CCD rig cameras, video-frequency monitor and power supply.Two CCD rig cameras comprise: first charge coupled cell (can adopt model is the colored CCD of ICX409AK) that can only respond to visible light, not only can respond to visible light for one and also can respond to second charge coupled device of infrared light (can adopt model is the black-white CCD of ICX409AL), the image-signal processor of an exportable analog video signal (can adopt model is that the digital signal processor of CXD3172R is DSP), light-sensitive element, voltage comparator (adoptable model is BA10393), a singlechip controller (adoptable model is PIC12C508) and electronic switch parts that are subjected to singlechip controller control.Wherein, the output of first charge coupled cell and second charge coupled device is the input of map interlinking image signal processor respectively, the input of the output termination video-frequency monitor of image-signal processor, light-sensitive element and voltage comparator join, the input of the output order sheet machine controller of voltage comparator, the control end of the output of singlechip controller and electronic switch parts joins, power supply is coupled to first by the electronic switch parts, the feeder ear of two charge coupled devices, depend on the control signal of singlechip controller output, power supply via the electronic switch parts to first, two charge coupled devices are selected a power supply.
