High-altitude satellite heater electronic control system and method

Abstract

The invention provides a high-altitude satellite heater electronic control system and method. The high-altitude satellite heater electronic control system comprises an instruction latching module, an instruction driving module and a control output module. The instruction latching module, the instruction driving module and the control output module are integrated. The instruction latching module converts instant heater control instructions into continuous control instructions. The continuous control instructions generate execution signals controlling the positive and negative ends of a heater respectively after passing through the instruction driving module. Finally, the execution signals are output by the control output module at the same time to be applied to the two ends of the heater, so that the whole satellite is thermally controlled. According to the high-altitude satellite heater electronic control system and method, the electronic switch control mode is adopted, the high-altitude satellite heater is controlled, the positive and negative ends of the heater are controlled at the same time, and reliability is high; a large number of electronic switches are adopted, so that the weight is low, and the size is small; due to the fact that the integrated design is supported, the high-altitude satellite heater electronic control system and method have the advantage of being suitable for the high-altitude satellite with multiple thermally-controlled circuits, the complex control mode and the severe operating environment.

Description

technical field [0001] The invention relates to the technical field of satellite thermal control subsystems, in particular to an electronic control system and a control method for a high-orbit satellite heater. Background technique [0002] At present, the control method for the satellite thermal control heater is basically a mechanical switch, that is, a relay, and the control of the heater is generally a single-ended control method. [0003] High-orbit satellites have complex structures and harsh operating environments. The number of thermal control heaters implemented on the entire satellite is large, the control methods are complex, and the reliability requirements are high. The control circuit of the traditional heater control method is large in size, heavy in weight, low in integration, and low in reliability, and cannot adapt to new demands. [0004] At present, there is no description or report of the technology similar to the present invention, and no similar mater...
