Type of slip ring carried by the aerostat

Such high-altitude scientific researchballoons and airships that operate in the near space usually carry scientificgondolas, which are equipped with various precision instruments and attitudecontrol systems. The payload of these balloons and airships is similar to thatof satellites. In space, satellites generally have corresponding slip rings to ensureproduct reliability, rather than adding a new slip ring to other equipment.

Therefore, slip rings may also be installedin the attitude control system of many aerostats. Especially for some mooredballoons or airships, their attitude control is usually controlled by groundcontrol stations. Compared with satellite payloads, airships used for nearspace missions, especially heavy-duty airships, may carry multiple slip rings,such as slip rings for attitude control systems and slip rings required forobservation or testing equipment in the payload.

In the extensive product portfolio of JINPAT,many models of slip rings have the ability to operate normally in extremely lowtemperature environments in close proximity. Among these slip rings, JINPATspecializes in products that integrate SDI high-definition signals, mainlyincluding multi-channel capsule and small hollow shaft products, all of whichbelong to deeply customized slip rings.

Let's take a look at one of the large-sizedmultifunctional integrated slip rings, which has a total length of 1447mm and amaximum diameter of 390mm. This product was developed by JINPAT specificallyaccording to the GJB technical standards related to the near-space environment,with a very high degree of integration, and is currently unique. Its productmodel is LPT000-02200-08180-1060-2110-2701-22S-FO02-HF02, and it integrateshigh-power power module (voltage 270VAC), weak signal module, optical signalmodule, and RF signal module. The optical signal module uses a 2-channelmultimode fiber optic slip ring, and the operating frequency of the RF signalmodule is 1.2~1.65GHz. This module uses the wiring method of a conventionalslip ring, rather than a dedicated high-frequency rotary joint.

Although this slip ring is large in sizeand has many functions, its protection level reaches IP65. To ensure thereliability of the product, it adopts a special structural design, withseparate physical isolation between modules and strong signal anti-interferenceability. This integrated slip ring has the ability to resist vibration andimpact in one go, and meets the requirements of EMC electromagneticcompatibility. In addition to this large-scale integrated slip ring withmultiple modules, JINPAT also has a large number of small integrated slip rings,which are mainly used in scientific research high-altitude and near-spacefloating balloons and airships, and their integrated functions are alsodifferent.
