Problems solved by technology

[0003] In the past, the ground power supply had short-term power outages when the main machine was abnormal and needed to switch to the auxiliary machine, and the main and auxiliary machines needed to be controlled separately. The control system was complicated, and short-term power outages easily affected the failure of electrical equipment.
This has been unable to meet the requirements of high integration, high reliability and high intelligence of existing ground equipment

Abstract

A direct-current power supply parallel control system comprises a host power supply, a sub-machine power supply and power supply remote control equipment. The input end of a first isolation diode is connected with the host power supply. The input end of a second isolation diode is connected with the sub-machine power supply. The output end of the second isolation diode is connected with the output end of the first isolation diode and is connected with a load at the same time. The host power supply and the sub-machine power supply both comprise remote control input circuits, remote control parallel circuits and power supply modules. The remote control input circuits are connected with the remote control parallel circuits and the power supply modules. The power supply remote control equipment is connected with the remote control input circuit of the host power supply. The remote control parallel circuit of the host power supply is connected with the remote control parallel circuit of the sub-machine power supply and is used for transmitting remote control signals to the sub-machine power supply. The voltage of the host power supply is higher than the voltage of the sub-machine power supply, and the voltage difference value is equal to the threshold voltages of the first isolation diode and the second isolation diode.

Description

technical field [0001] The invention relates to the field of circuit control systems, in particular to a DC power parallel control system. Background technique [0002] In large or important systems, there are usually two power supplies, one as the main power supply and the other as the auxiliary power supply. When the main power supply fails, the auxiliary power supply is replaced to ensure the normal operation of the system. Take the launch of a launch vehicle as an example: the ground power supply of the launch vehicle integrated measurement, launch and control system is mainly used to supply power to the single machine on the rocket, the combination of measurement, launch and control, and the equivalent system, and is to verify the equipment on the rocket, the path of the rocket to the ground, and the ground. important component of equipment effectiveness. Therefore, the reliability of ground power supply directly determines whether the arrow and ground equipment work n...
