Problems solved by technology

Only a small amount of intuitive information needs to be injected on the ground. After the computer on the star receives and analyzes it, it can independently search, judge and set the temperature control data, which solves the problem that the above-mentioned data is complex, error-prone, and difficult to develop online

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0030] 1) Create a data lookup table and store it

[0031] The ground users classify and number the thermistors on the star according to the model, and sort out the typical temperature of the thermistor, the voltage value of the temperature measurement circuit where the thermistor is located, the serial number of the thermistor and the temperature control circuit within the preset temperature working range. The mapping relationship of numbers can be established to independently query the data table. The following takes MF501 and G2a thermistors as examples to illustrate the specific implementation process.

[0032] figure 2 Among them, table a shows the corresponding relationship between the thermistor serial number and serial number, the first half of the number represents the thermistor type number, and the second half represents the rankin...

Abstract

The invention provides a search table based satellite temperature control data processing method. The method is that a search table is built according to the information basis of the mapping relationship between the heat sensitive resistor temperature and the voltage of temperature measuring loop of a heat sensitive resistor and the correspondence relationship between a heat sensitive resistor number and a temperature control sequence number; three-die redundancy storage is performed in a satellite; a ground user can arrange and transmit an instruction according to an instruction template, and the satellite receive and analyzes the instruction to automatically perform temperature control setting, search table information increasing, modifying or deleting and other tasks. According to the method, the WYSIWYG mode is utilized to perform temperature control management; the complexity of ground operation is reduced; the risk is reduced; meanwhile, the high maintenance performance of the search table provides thermal technical assurance for later development of intelligent satellite software and hardware dynamic development technology.

Description

technical field [0001] The invention belongs to the technical field of thermal control, and relates to a satellite temperature control data processing method based on a lookup table. Background technique [0002] At present, in the process of satellite temperature control data processing, the ground needs to select an appropriate temperature control circuit according to the position of the temperature-adjusting equipment or structural board. Then, a thermistor at the associated temperature measurement point is selected as a reference object to give a reasonable temperature control threshold. After complex formula calculations, the magnitude of the voltage corresponding to the opening / closing threshold is calculated, and it is generally necessary to artificially take an approximate value. Finally, parameters such as the temperature control circuit number, temperature control mode, reference thermistor number, and voltage value corresponding to the temperature control thresho...
