Abstract

The invention provides an on-rocket electrical system of a carrier rocket, which comprises a master control electrical subsystem and at least one sub-control electrical subsystem, and each of the master control electrical subsystem and the sub-control electrical subsystem comprises at least one functional device and a wireless sensor node. The functional devices and the wireless sensor nodes respectively comprise a corresponding power supply unit and a wireless communication unit, the main control electrical subsystem further comprises a wireless center node and a comprehensive control computer which are electrically connected, and power is uniformly supplied through the corresponding power supply units. Each sub-control electrical subsystem further comprises at least one relay forwarding antenna which is used for receiving data sent by the functional equipment in the corresponding sub-control electrical subsystem and the wireless sensor node through the corresponding wireless communication unit and forwarding the data to the wireless center node; and the relay forwarding antenna is also used for receiving a control instruction sent by the comprehensive control computer through the wireless center node and forwarding the control instruction to the target equipment. The loading capacity and the production efficiency of the rocket can be improved, and the use cost is reduced.

Description

technical field [0001] The present application relates to the field of aerospace technology, and in particular, to an on-board electrical system of a launch vehicle. Background technique [0002] The electrical system on the rocket is a general term for the functions of electrical, electronic equipment and software, and is an important part of the launch vehicle. figure 1 Shown is a schematic structural diagram of the electrical system on the arrow of a launch vehicle in the prior art, such as figure 1 As shown, the electrical system on the arrow adopts a centralized wired structure, and each component in the system is connected by a cable network.
