Description

technical field [0001] This application relates to the field of aerospace, in particular to a communication system for ground measurement, launch and control of rockets. Background technique [0002] In the existing aerospace rocket testing field, the ground measurement and launch control system is divided into remote equipment and near-end equipment. The distance between the front-end equipment and the front-end equipment is several kilometers, and the two are connected by optical cables to achieve the purpose of long-distance control. The near-far end communication of the ground measurement, launch and control system uses traditional wired communication methods, such as the well-known RS422, RS485, 1553B, CAN, Ethernet and other bus forms. The more mainstream solution is to use Ethernet as the wired information transmission medium, and for long-distance transmission, convert electrical signals into optical signals and transmit them through optical fibers. This wired trans...

Problems solved by technology

[0004] First, in the initial stage of cable product development, it is often unknown which launch site and launch station the rocket will be launched at. Different launch sites and different launch stations have different requirements for cable length. In order to adapt to various possible situations , the length of the cable network can only be considered according to the farthest distance, which often leads to an excessive cable network margin; for some inexperienced designers, it may even result in insufficient cable network length and the need to re-start production, affecting schedule and cost

[0005] Second, the length of the cables between the near and far ends of the ground is often at the kilometer level. In the preparation stage of the launch site, cable laying and protection are required, which often takes half a day to a day. This not only results in the cost of occupying the launch site, but also This is clearly a constraint to the increasing demand for rapid launches

[0006] Third, the glass core in the optical fiber is relatively fragile. If it is subjected to excessive pressure, the core will be damaged or damaged. If it is stepped on or pressed by a heavy object during daily testing, it may cause some hidden dangers. These Risks are likely to be concealed from testers, adversely affecting reliable launches

Facing the demand for simultaneous transmission of multiple signals, traditional wired communication methods are difficult to meet the demand for simultaneous transmission of multiple types of signals relying on a single device

[0008] One solution is to change the system architecture and add corresponding communication equipment, which will bring a huge cost burden

Moreover, the transmission distance of commonly used communication methods is generally short, and optical fiber transmission equipment must be added to achieve long-distance transmission. This not only brings cumbersome procedures for deployment and withdrawal, but also increases intermediate transmission links, bringing many uncertain factors
