Embodiment Construction

[0044] like figure 2 As shown, a control method for autonomous switching of a highly reliable circulating pump according to an embodiment of the present invention includes the following steps:

[0045] S1. During the operation of the on-duty circulating pump in the heat dissipation circuit, according to the preset frequency, collect and judge whether the on-duty circulating pump fails according to the state data of the on-duty circulating pump, and obtain the first judgment result;

[0046] S2. When the first judgment result is yes, determine the off-duty circulation pump in the cooling circuit as the on-duty circulation pump, and control the operation.

[0047] The two circulating pumps are used alternately. The on-duty circulating pump and the off-duty circulating pump are defined according to whether the pump is powered on. It can also be understood as: the on-duty circulation pump refers to the circulation pump that is running, and the off-duty circulation pump refers to...

Abstract

The invention relates to a high-reliability circulating pump autonomous switching control method and system and a controller, and the method comprises the steps: in the operation process of an on-duty circulating pump in a heat dissipation loop, collecting state data of the on-duty circulating pump according to a preset frequency, and judging whether the on-duty circulating pump breaks down or not according to the state data, so as to obtain a first judgment result; and when the first judgment result is yes, the non-on-duty circulating pump in the heat dissipation loop is determined as the on-duty circulating pump, and operation is controlled, that is, the non-on-duty circulating pump can be automatically started to operate, the time consumed by automatic switching is short, potential safety hazards caused by an active heat dissipation system are avoided, and the reliability is high.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a control method, system and controller for autonomous switching of a highly reliable circulating pump. Background technique [0002] Two circulating pumps are designed inside the active heat dissipation circuit, such as figure 1 As shown, each circulation pump corresponds to a driver, and the driver is powered by an independent power supply box, specifically: [0003] The two circulation pumps are respectively the first circulation pump 3 and the second circulation pump 8, the driver corresponding to the first circulation pump 3 is the first circulation pump driver 2, the power supply box is the first circulation pump power supply box 1, and the first circulation pump power supply The box 1 is connected to the first circulation pump driver 2 through the first cable 4, the first circulation pump driver 2 is connected to the first circulation pump 3 through the second cable 5,...
