Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 2 As shown, compared with the traditional measurement system ( figure 1 Compared with that shown), the present invention cancels the front-end junction box located in the front room of the test run, optimizes the cable transfer mode by adding a switch cabinet, and redesigns the wiring panel according to different types of slowly changing parameters to realize the transfer of different types of slowly changing parameter signals connection and monitoring. The quantity data involved in the following, such as the specific quantity of sockets, measurement channels, and wiring panels, can be adjusted according to task requirements.

[0040] From image 3 It can be seen that in order to meet the requirements of the test task, the transfer cabinet in this embodiment includes 96 sockets in 12 rows and 8 columns evenly distribut...

Abstract

The invention relates to an engine parameter measurement system, and in particular relates to a high-reliability measurement system capable of simultaneously acquiring multiple types of parameters. The problem that the measurement reliability of a traditional measurement system is low due to the wiring mode of a junction box and a wiring panel is solved. The system comprises a movable cable, and awiring panel assembly, a front-end acquisition cabinet, a cRIO distributed acquisition system, a coil holder trunking, an adapter cabinet and an adapter cable which are located in a front equipment room. By additionally arranging the adapter cabinet, the cable adapter mode is optimized, and the wiring panel is redesigned according to different types of slowly changing parameters, so that switching and monitoring of different types of slowly changing parameter signals are realized.

Description

technical field [0001] The invention relates to an engine parameter measurement system, in particular to a high-reliability measurement system for simultaneously collecting multiple types of parameters. Background technique [0002] The engine ground test is an important part of each stage of engine development. It is the verification and verification of the feasibility, correctness, and stability of the production process of the engine design scheme. and the only means of acceptance. [0003] The purpose of the engine test is to obtain various parameters of the engine. Slowly changing parameters such as thrust, pressure, temperature, vacuum pressure, flow rate, and rotational speed are important indicators for evaluating engine performance, and are the basis for real-time grasp of the working status of the engine and test system. The original waveform data of vibration, pulsation pressure, and rotational speed are important parameters for engine process verification and t...
