Measurement and control system for test network and data acquisition control method

Abstract

The invention relates to a measurement and control system for a test network and a data acquisition control method. The measurement and control system comprises a front-end acquisition device, an equipment control device, a data acquisition device, a data view display device, a data submission device, an acquisition / receiving monitoring device, a calculating control device, a data receiving device, a data release device, a monitoring device, a receiving device, a data processing device, a graphic display device and a storage device, wherein in the system, after being capsulated uniformly by utilizing the data acquisition device, sampled data is decapsulated by the data release device to form a standard data pack to be transmitted to the receiving device; the transmission processing time of each acquisition module in the front-end acquisition device is calculated by the calculating control device; simultaneously, the data acquisition device is controlled according to revised data of the data processing device. In the measurement and control system, the capacity of integration, informatization, intellectualization and integral test is improved, the capacity of calculating and acquiring loads is balanced effectively, and signal flow acquired dynamically can be acquired and processed efficiently, so that the measurement and control system for the test network can deal with a complex measurement and control scheme.

Description

technical field [0001] The invention relates to the field of engine test data collection, in particular to a test network measurement and control system and data collection control method for test data collection, display, release and reception. Background technique [0002] The engine is a high-power component that works under the condition of a wide range of parameters of the working fluid. It is also the component that consumes the most in the testing of electromechanical components and has relatively complicated testing techniques. is constantly improving. The engine test mainly includes: acquisition characteristics, determination of stable working boundary, flow loss test research, and checking the reliability of the regulating system. [0003] Engine Pilot Test Features: [0004] 1) There are many measurement parameters: [0005] The more data measured by the engine test, the richer the information obtained, the more thorough understanding of the engine's working ch...

Problems solved by technology

[0008] 3) The environmental conditions of the measurement parameters are poor:

[0010] 4) High reliability requirements:

[0014] 6) High data management requirements:

This consumes manpower and cannot guarantee that the test operation is accurate and free from human factors, and people who are not at the test site cannot see the test process and have no ability to conduct overall tests on the test data

[0017] More importantly, due to the huge amount of experimental data, the computer system cannot process massive data in a timely manner. As the data collection point in the test is affected by the interference factors generated by the operation of other components, the hardware filtering efficiency of the acquisition system is reduced, making valid data submerged in it. When collecting data at the same time, too much data loss leads to repeated resampling
