Problems solved by technology

[0004] Most of the traditional power distribution still adopts the control method of electromagnetic relay, which has the following defects: First, in order to ensure reliable power distribution and testing needs, it is necessary to adopt a redundant design in which multiple electromagnetic relays are connected in parallel through welding wires, and then through welding wires Connect the relay to the external connector, and use cables to build a large number of logic control circuits
Although this method is simple, it is heavy
Second: The electromagnetic relay is large in size, which is not suitable for soldering on the circuit board, and is not conducive to the integrated design of the equipment. Therefore, the traditional relay and distributor are often set up as a separate device, occupying the space on the arrow.
Third: The electromag

Embodiment 1

[0035] The application provides a digital power supply and distribution control system for a launch vehicle, including a power distribution control system for intelligent equipment and a power distribution control system for pyrotechnics. The length of the launch vehicle is relatively long, so the two ends of the rocket are respectively equipped with an intelligent equipment power distribution control system and an explosive power distribution control system. Such as figure 1 , 2 As shown, the intelligent device power distribution control system and the pyrotechnic product power distribution control system are respectively equipped with an instrument battery 11 and a pyrotechnic battery 21, so as to reduce the power consumption of the intelligent device power distribution control system and the pyrotechnic product power distribution control system powered by the same battery. Voltage loss due to long cables.

[0036] Both the intelligent equipment power distribution control ...

Embodiment 2

[0047] The present application also provides a test method for the digitalized power supply and distribution control system of the launch vehicle matched with the digitalized power supply and distribution control system of the launch vehicle in Embodiment 1.

[0048] The ground measurement and control system sends commands to close or disconnect each switch to the intelligent equipment power distribution control system and the pyrotechnic power distribution control system through Ethernet;

[0049] Each switch combination in the digital power supply and distribution control system of the launch vehicle executes the command after receiving the command;

[0050] Such as image 3 , 4 As shown, the data collection points 13, 14, 15, 23, and 24 are connected to the ground measurement and control communication, and the collection points 13, 14, 15, 23, and 24 are used to transmit the collected data to the ground measurement and control via Ethernet. Launch control, the data is dis...

Abstract

The invention discloses a carrier rocket digital power supply and distribution control system and a test method thereof. The system comprises a plurality of switches. The plurality of switches receivedigital instructions sent by the ground test launch controller through the Ethernet so as to execute closing or opening actions; the carrier rocket digital power supply and distribution control system sends collected test data to the ground test launch control system through the Ethernet for analysis. Digital instructions and test data are transmitted through the Ethernet, and the problem that acable used for ground test launch control is not used any more after a rocket takes off and becomes redundant load on the rocket is solved.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a digital power supply and distribution control system for a launch vehicle and a testing method thereof. Background technique [0002] Compared with digital circuits and bus communication, the power supply and distribution system of my country's launch vehicles develops relatively slowly. The traditional power distribution control system and testing require many cables. Due to the needs of ground testing and logic control, many cables are directly led to the ground test and control system, and the ground test and control system performs multi-channel power distribution control, which greatly increases the number of arrows. The weight of the upper cable network, and many of these cables will not be used after take-off, these cables become unnecessary loads, affecting the rocket's carrying capacity. [0003] There are often multiple power supply and distribution systems on the launch veh...
