Abstract
The invention relates to a device for testing a satellite command and discloses a portable satellite equivalent device. The portable satellite equivalent device comprises a level conversion module (201), an analog signal isolation module (202), a digital-to-analog convert module (203), a digital signal processing module (204) and a liquid crystal display control module (205), wherein a signal to be tested enters the level conversion module (201) on a control circuit board (2), is converted into an LVTTL (Low Voltage Transistor-Transistor Logic) level signal according to a ratio, is subject to linear high resistance isolation through the analog signal isolation module (202) and is then sent to the digital-to-analog convert module (203); an analog signal is converted to a digital signal with the precision of 12 bits by the digital-to-analog convert module (203) and is then output to the digital signal processing module (204); and related parameters of the signal to be tested are displayed on a liquid crystal display (6) through the liquid crystal display control module (205). The invention solves the problem of the heavy satellite equivalent device in the prior art and has the advantages of convenient carrying, simple, convenient and quick testing, and the like.
Description
Technical field
The present invention relates to a kind of proving installation of satellite instruction, especially a kind of portable satellite simulator.
Background technology
The satellite simulator is that employing is verified the validity of key instructions such as breakaway plug electricity separation command, band unlock command and emergency cutoff instruction and reached the specialized equipment of testing these instructions.
The satellite simulator of prior art generally adopts digital watch to show the correlation parameter of tested instruction, because the digital watch own vol is bigger, and can only show the single parameter of a tested instruction at synchronization.In order to satisfy the instruction number and the bigger requirement of parameter sum thereof of synchronization test, equipment volume will be huger, more is not easy to portably use.The present invention is exactly a kind of proving installation in order to address the above problem.
Do not find at present the explanation or the report of technology similar to the present invention, do not collect both at home and abroad similarly data as yet yet.
Summary of the invention
Bulky for the satellite simulator that solves prior art, as to be not easy to portably use problem, the object of the present invention is to provide a kind of portable satellite simulator to utilize the present invention, not only reduce the volume of simulator, and can test and handle a plurality of data simultaneously.
In order to reach the foregoing invention purpose, the technical scheme that the present invention is adopted for its technical matters of solution provides a kind of portable satellite simulator, and this device comprises:
Portable hand suitcase type shell, installing device installing plate, control circuit board, device panel and LCDs successively from bottom to top in the case; Wherein: LCDs via screw retention on device panel; Control circuit board is fixed on the device mounting board by extension bar; Device panel and device mounting board are fixed in the portable hand suitcase type shell by securing member is installed.
The cable of measured signal is connected with connector on the said equipment panel, measured signal enters the level switch module on the above-mentioned control circuit board, be converted to the LVTTL level signal in proportion, again via the simulating signal isolation module carry out linear high-barrier from after send into D/A converter module, is that precision is to input to digital signal processing module after 12 the digital signal by it with analog signal conversion, demonstrate the correlation parameter of measured signal at last in LCDs by the LCD Controller module, supply module is connected with supply socket on the device panel, and the internal electric source of above-mentioned each module is provided.
A kind of portable satellite simulator of the present invention, owing to take above-mentioned technical scheme, structurally adopt the design of portable hand suitcase, and utilize high-speed dsp to handle measured signal, by the various parameters of large-sized liquid crystal display demonstration measured signal, overcome the shortcoming of the satellite simulator equipment heaviness of prior art then.The present invention proves that through the examination of every experimental test in ground and satellites transmits test its technical scheme is effective, safe and reliable.Therefore, the present invention has obtained the easy beneficial effect such as fast of easy to carry, test.Simulator of the present invention can be common to various model satellites and other spacecrafts.
