Embodiment Construction

[0041] Combining with domestic aerospace and aero engine tests, the inventors of this application independently developed a set of engine test distributed control system and method, which solved the problems of high cost, later maintenance, function expansion and integration difficulties caused by imported control systems .

[0042] The following is attached figure 1 The system structure of the present invention is described:

[0043] The control system includes an upper computer, a network switch, at least four lower computers and corresponding drive units and acquisition units; among them, the upper computer adopts the windows system; the lower computer adopts the Linux system; the upper computer and the lower computers transmit data through Ethernet Interaction; each lower computer controls the switch of several valves through the drive unit, and at the same time collects the switch status of several valves through the acquisition unit;

[0044] Among them, a lower comput...

Abstract

The invention belongs to the technical field of aerospace engineering, and relates to an engine test system and method, in particular to an engine test collecting-distributing type control system and method. The engine test collecting-distributing type control system comprises an upper computer based on the windows system, a plurality of lower computers based on the Linux system, an network switch for achieving interaction between the upper computer and the lower computers, a corresponding driving unit and a corresponding acquisition unit. The engine test collecting-distributing type control system guarantees accurate and real-time transmission of data through the methods that the upper computer and the lower computers adopt a TCP / IP communication protocol, the inventor defines fields of a protocol packet, and the protocol packet adopts IP addresses and a packet head which are bound for testing. By means of the engine test collecting-distributing type control system and method, the problems of high cost and difficult later maintenance and function extension and integration due to the fact that an engine test control system in the technical field of aerospace engineering needs to be imported are solved.

Description

technical field [0001] The invention belongs to the technical field of aerospace. The invention relates to an engine test system and method, in particular to an engine test distributed control system and method. Background technique [0002] The basic equipment generally used in aerospace and aero-engine ignition tests includes various types of valves, storage tanks and corresponding pipelines, control systems, etc. The various fuels required for the engine test stored in the storage tank are regulated by closed-loop pressure, and after reaching the pressure required by the system, the various fuels required for the engine test are passed through the pipeline and then through various types of valves according to a certain sequence of switching actions. Finally, it is delivered to the engine, where the engine is ignited to start the test. [0003] In addition, the driving unit of the control system generates the voltage and current conditions required for the valve action a...
