Abstract
The utility model relates to a device for tracking the sun for high altitude balloon test, which is the tracking device to be required to observe the sun and an atmosphere ultraviolet spectrum in an atmosphere stratosphere. The utility model comprises a pitching angle /azimuth angle drive mechanism 1, a four-quadrant detector 2, an electronics control system 3, a sun/ ultraviolet spectrum radiometer 4. A bearing of the utility model adopts the lubrication of molybdenum disulfide solid lubricant to guarantee the normal work of the utility model under the conditions that a temperature is about-60 DEG C and a vacuum degree is about a few mm Hgs in an environment. The pitching angle /azimuth angle drive mechanism is adopted to make the utility model have the advantages of compact structure, good symmetrical performance, small size, light weight, flexible following system rotation and small time constant.

Technical field:
The utility model belongs to the spectral technique field, relates in the atmospheric advection layer observation sun and the required tracked instrument of atmosphere ultraviolet spectrum.
Background technology:
Nearly two, 30 years, the sun/atmosphere ultraviolet band spectrum observation research was very active in the world.For adapting to the needs of international development and domestic correlative study, the end of the eighties is under the 863-2 project support, the Changchun ray machine is developed into the sun/atmosphere ultraviolet spectrum radiation and takes into account the ground tracking means that matches and carried out the long-term sun/atmosphere ultraviolet spectrum ground observation, obtains many valuable data informations.At the beginning of the nineties, deploying solar/atmosphere ultraviolet band spectrum aerological Observation test has been developed the device that adapts to the tracking sun that shows unique characteristics of aerostat environment.The device of following the tracks of the sun is a servomechanism, can carry out comprehensive search, follow the tracks of the sun (0～360 ° rotation ,-10 °～90 ° pitching), guarantee owing under the situation of time variation and the rotation of aerostat hanging basket, sun altitude and azimuthal variation, make the optical axis of the sun/atmosphere ultraviolet spectrum radiometer of installing on it aim at the sun all the time.When carrying out the measurement of atmospheric backscatter ultraviolet spectrum, make the optical axis of the sun/atmosphere ultraviolet spectrum radiometer point to the earth's core by catoptron.Mechanical driving device in traditional solar follow-up device can not adapt to high altitude environment running, and the 4 quadrant detector that is adopted is subjected to the influence of gondola lifting rope, makes the 4 quadrant detector no-output cause solar tracking to lose efficacy.Traditional tracking solar system structure is excessive, symmetry is bad, volume is big, weight is big, the system angle momentum change was very big when crotch rotated, and the servomechanism rotation is dumb, time constant is big, therefore needs to use expensive angular momentum fly wheel system stablize the gondola that is carried.
The utility model content:
Excessive in order to solve the background technology structure, symmetry is bad, volume is big, weight is big, the system angle momentum change was very big when crotch rotated, and servomechanism is rotated dumb, the problem that time constant is big, carry out the sun/atmosphere ultraviolet spectrum when the purpose of this utility model provides a kind of high-altitude balloon experiment and observe the device of the needed tracking sun, guarantee because under time variation and aerostat hanging basket rotation sun altitude and the azimuthal variation situation, the optical axis of the sun on the gondola/atmosphere ultraviolet spectrum radiometer is aimed at the sun all the time, when carrying out the measurement of atmospheric backscatter ultraviolet spectrum, the optical axis of the sun/atmosphere ultraviolet spectrum radiometer points to the earth's core by catoptron.
The utility model is made up of the angle of pitch/position angle driving mechanism, 4 quadrant detector, electronics control system and the sun/atmosphere ultraviolet spectrum radiometer, as shown in Figure 1:
The axle of transverse axis stepper motor in the angle of pitch/position angle driving mechanism and Z-axis stepper motor is connected with an end of horizontal shaft coupling and vertical shaft coupling respectively, horizontal shaft coupling is connected with the end of horizontal worm screw and vertical worm screw respectively with the other end of vertical shaft coupling, horizontal worm screw meshes with vertical worm gear with horizontal worm gear respectively with vertical worm screw, and horizontal rotating shaft is connected with vertical worm gear with horizontal worm gear respectively with vertical rotation axis; 4 quadrant detector is connected with two-value treatment circuit in the electronics control system.
Be applied to the duty of device of the tracking sun of high-altitude balloon experiment:
The sun/atmosphere ultraviolet spectrum radiometer requires it to be operated in when following the tracks of sun mode, then drives solar follow-up device and carries out orientation and pitching scanning.At first preset initial angle, Single-chip Controlling stepper motor driving circuit in the electronics control system drives the horizontal stepper motor in the angle of pitch/position angle driving mechanism, drive horizontal worm screw and horizontal worm gear by horizontal shaft coupling, drive horizontal rotating shaft and carry out sun search ± 200 ° scope.The status information that transmits according to 4 quadrant detector through the two-value treatment circuit, is differentiated the sun whether in field range.As in the visual field, then enter the sun mode of following the tracks of.Otherwise single-chip microcomputer drives vertical stepper motor by stepper motor driving circuit, drives vertical worm screw and vertical worm gear by vertical shaft coupling, drives vertical rotation axis and strengthens luffing angle, proceeds sun search, until entering the state of following the tracks of the sun.
When following the tracks of sun state, the telescopic system that Taiyang channel is crossed in the sun/atmosphere ultraviolet spectrum radiometer is imaged on the focal plane of 4 quadrant detector.When the 4 quadrant detector output signal is balanced, show that then the sun is on the optical axis of telescopic system.Because the optical axis of the sun/atmosphere ultraviolet spectrum radiometer is parallel with the center of 4 quadrant detector, the device of following the tracks of the sun is when tracking mode, and the sun also is on the optical axis of ultraviolet spectrum radiometer, and solar radiation enters the ultraviolet spectrum radiometer.The device of following the tracks of the sun sends instruction to the ultraviolet spectrum radiometer after entering and following the tracks of sun state, begins to carry out the measurement of solar ultraviolet spectrum.
When carrying out the atmospheric backscatter spectral measurement, the positioning signal that solar follow-up device produces according to the Hall setting element through Hall element locating query circuit, is positioned the ultraviolet spectrum radiometer for the aeromerric moasurenont orientation exactly by single-chip microcomputer, tests.
Characteristics of the present utility model: the system bearing of solar follow-up device adopts the molybdenum disulfide kollag lubricated, can guarantee to be about in temperature operate as normal in the environment that-60 ℃, vacuum tightness are about several mm Hg; Follow the tracks of the device of the sun owing to adopt the angle of pitch/position angle driving mechanism, thereby make compact conformation, symmetry is good, volume is little, in light weight, and servomechanism is rotated flexibly, time constant is little, therefore need not to use expensive angular momentum fly wheel system to stablize the gondola that is carried; The utility model adopts the telescope type 4 quadrant detector, and balloon hangs blue lifting rope only influences light intensity on the detector, avoids because balloon hangs blue lifting rope is in the light and makes the 4 quadrant detector no-output, the problem that causes solar tracking to lose efficacy.The utility model is not use expensive angular momentum fly wheel system to stablize gondola in the world first, successfully carries out the system of solar tracking.
Carry out the sun/atmosphere ultraviolet band spectrum aerological Observation test in 1997, achieved success, obtained 32 kilometers height place sun/atmosphere ultraviolet band spectroscopic data data.
