Embodiment Construction

[0023] Hereinafter, the present invention will be further described in detail with reference to the drawings and embodiments.

[0024] This embodiment provides a ground test equipment that can convert a satellite non-standard image interface into a standard HDMI interface, and perform image split-screen display, remote measurement parameter display, and command simulation.

[0025] Such as figure 1 As shown, the ground test equipment integrates the touch screen 1, the display 2, the cable socket 4, the power interface 5, and the power supply switch 6 on a chassis shell 3, and connects the ground test equipment with the cable set on the cable socket 4 Connect the dual-spectrum camera under test.

[0026] Wherein, the touch screen 1 is embedded in the top of the chassis shell 3 in the form of a panel. The display 2 is mounted to one side of the case shell 3 through a bracket. The cable socket 4 is fixed to the front panel of the chassis shell 3 by screws, and the connected cable can ...

Abstract

The invention provides ground testing equipment for a satellite-borne double spectrum camera. A touch screen, a display, a cable socket, a power interface, a power supply switch and the like are integrated on a case shell, and by virtue of a cable arranged on the cable socket, the ground testing equipment is connected with a tested double spectrum camera for communicating and power supply. Remote sensing parameters reflecting an operating state of the double spectrum camera are displayed on the touch screen in real time, and instructions for controlling an operating mode and the like of the double spectrum camera are transmitted. By virtue of a built-in electronic circuit and control unit, a common non-standard image interface protocol on a satellite is converted into a standard HDMI (High-Definition Multimedia Interface) protocol, so that infrared and visible light images or videos output by the satellite-borne double spectrum camera are displayed in the same screen in real time in a split screen manner. According to the ground testing equipment disclosed by the invention, a bridge is built between a satellite-borne image or video interface and an industrial general image or video interface, and support is provided for ground testing of the satellite-borne double spectrum camera.

Description

Technical field [0001] The invention relates to a ground test technology for a spaceborne camera, in particular to a ground test equipment for a spaceborne dual-spectrum camera. Background technique [0002] Photoelectric imaging technology is one of the most intuitive and commonly used ways to observe space activities. Therefore, currently domestic and foreign spacecraft are generally equipped with surveillance cameras to image and even broadcast real-time images of observation targets, such as the American "Curiosity" Mars rover, China's "Shenzhou" spacecraft and "Chang'e-3" aircraft. [0003] The development of spaceborne cameras is inseparable from ground testing. At present, the communication interfaces of satellite platforms mainly include: RS422, CAN, 1553B and LVDS, etc. Due to the large amount of image signal data, a relatively high-speed LVDS interface is generally used for transmission. At present, the commonly used image or video interfaces in the industrial field ma...
