Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] This embodiment provides a ground test device, which can convert the non-standard image interface on the star into a standard HDMI interface, and perform image split-screen display, telemetry parameter display, and command simulation.

[0025] Such as figure 1 As shown, the ground test equipment integrates a touch screen 1, a display 2, a cable socket 4, a power interface 5 and a power supply switch 6, etc. on a chassis shell 3, and the ground test equipment is connected to the ground test equipment through the cable provided on the cable socket 4. The bispectral camera under test is connected.

[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 casing 3 through a bracket. The cable socket 4 is fixed to the front panel of the chass...

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 space-borne camera, in particular to ground test equipment for a space-borne dual-band camera. Background technique [0002] Electro-optical imaging technology is one of the most intuitive and commonly used ways to observe space activities. Therefore, at present, spacecraft at home and abroad are generally equipped with surveillance cameras to image observation targets and even live broadcast space activities with real-time images, such as the US "Curiosity" Mars rover, China's "Shenzhou" spacecraft and "Chang'e 3" aircraft. [0003] The development of a spaceborne camera is inseparable from ground testing. At present, the communication interfaces of the satellite platform mainly include: RS422, CAN, 1553B and LVDS. Due to the large amount of image signal data, a relatively high-speed LVDS interface is generally used for transmission. At present, the image or video interfaces commonly used in t...
