Temperature control method of automatic deflation process detection of satellite storage box (air bottle)

Abstract

The invention provides a temperature control system of automatic deflation process detection of a satellite storage box (air bottle), comprising a temperature acquisition unit, a temperature control unit, an execution unit and a user interface, wherein the temperature acquisition unit comprises various temperature sensors and temperature modules, the temperature control unit comprises a PLC (programmable logic controller) module and software. The invention also provides a temperature control method for automatic deflation process detection of a satellite storage box (air bottle). The system and the method are suitable for temperature control of the automatic deflation process detection of the satellite storage box (air bottle) and are also applicable to automatic deflation temperature control of other similar workpieces. The system and the method solve the uncertainty and potential safety hazard for controlling by virtue of experience when the temperature is artificially and manually controlled in the deflation process of the satellite storage box (air bottle), and the great uncertainty caused by temperature inertia in the deflation process can be effectively avoided.

Description

technical field [0001] The invention relates to a temperature control method, in particular to a temperature control method for the leak detection and automatic deflation process of a satellite tank (gas cylinder). Background technique [0002] In the current satellite leak detection process, the deflation of the storage tank (gas cylinder) is completely controlled manually, so the temperature control method of the storage tank (gas cylinder) has always been the "manual manual control method on site". [0003] During the leak detection and deflation process of the satellite tank (gas cylinder), the temperature has an "inertia" that is difficult to determine, that is, when the deflation stops, the temperature will continue to change (rise) for a period of time before stopping, and this "A period of time" is hard to pin down. The on-site manual control method completely relies on the operator's experience or subjective will to control. Generally, the deflation is stopped in a...

Problems solved by technology

[0003] During the leak detection and deflation process of the satellite tank (gas cylinder), the temperature has an "inertia" that is difficult to determine, that is, when the deflation stops, the temperature will continue to change (rise) for a period of time before stopping, and this "a period of time" is difficult to determine

The on-site manual control method completely relies on the operator's experience or subjective will to control. Generally, the deflation is stopped in advance according to experience to prevent the temperature from exceeding the limit caused by "temperature inertia". Although this method is simple, it has many advantages. Large uncertainties and potential safety hazards, a little carelessness will cause the temperature to exceed the limit, the reason is analyzed, mainly because manual control relies entirely on experience, and it is not related to the operator, operation method, venting equipment, product characteristics and many other factors, with great uncertainty and potential safety hazards

[0004] With the acceleration of the aerospace industrialization process, the requirements for satellite batch production are becoming increasingly severe. Although the current on-site manual control method can realize leak detection and deflation of satellite storage tanks (gas cylinders) to a certain extent, due to its inherent artificial Uncertainty and potential safety hazards, and the need to be on duty at all times, the contradictions in human resources, time efficiency, etc. are becoming increasingly prominent
