Embodiment Construction
[0036] Such as Figure 1~4 As shown, a method for processing measurement data, including producer-consumer threads for data storage, and state machine threads for chart display, producer-consumer threads and state machine threads run in parallel, producer threads Push the data collected by the sensor into the queue message processor, the consumer thread reads the data from the queue message processor and saves it to the disk, and the state machine thread includes
[0037] Step one 101, the detection data is read by the acquisition module and stored in the waveform buffer array;
[0038] Step 2 102, 103, 104, 105, display tab charts in turn in sequence, tab charts include more than one waveform data formed by waveform buffer array filtering processing, waveform data includes "load & speed waveform display" waveform data, "Temperature waveform display" waveform data, "vibration waveform display" waveform data, "rotational speed & current waveform display" waveform data, the ord...

The invention relates to a measurement data processing method and device; the device comprises a producer-consumer thread used for data storage and a state machine thread used for chart display; the producer-consumer thread and the state machine thread run in parallel, the producer thread presses the data collected by a sensor into a queue message processor; the consumer thread reads data from the queue message processor and stores the data in a disk; the state machine thread stores the detection data read by the acquisition module in a waveform cache array, performs compression threshold judgment on the currently displayed waveform data, and performs lossy compression processing when the compression threshold is reached. According to the invention, technical optimization is carried out on data storage and data waveform display, and the problem of data waveform display detection in a long-time test process and the problem of data storage security during accidental power failure or system crash are solved.
Description
technical field [0001] The invention relates to a method and device for processing measurement data, especially suitable for the occasion of data processing and display for long-term tests. Background technique [0002] Existing testing and testing equipment processes the measurement data: After the data collected by the sensor is processed, the test status and trend are presented in the form of waveform diagrams. The waveform diagram displayed by the measurement device considers the limitation of physical memory. The conventional practice is to only intercept the latest data for display. The background stores the measurement data in the database in real time. This method is suitable for most occasions. However, in the life test of bearings and other products, the test runs in a cycle according to the step spectrum. The test time is long, and there are thousands of hours of tests. For the entire test running process, the test data and waveform display are saved. The amount o...
