Wave recorder anti-misoperation device, wave recorder and method

Abstract

The invention relates to a wave recorder anti-misoperation device, a wave recorder and a method, and comprises a cover body used for being installed at the function key of the wave recorder, and the cover body is movably provided with a control structure used for pressing the function key, a locking structure used for controlling the control structure to move, and a positioning structure used forcontrolling the locking structure. The function key is pressed by operating the control structure to enable the wave recorder to enter a working state; the control structure is limited through the locking structure, so that the control structure cannot flexibly press the function key so as to prevent misoperation; after the work of the wave recorder is finished, the limitation of the locking structure to the control structure is eliminated. According to the scheme, the misoperation of the wave recorder can be effectively prevented, and irreparable loss in work is avoided.

Description

technical field [0001] The invention relates to a device, a wave recorder and a method for preventing misoperation of the wave recorder. Background technique [0002] The oscilloscope is widely used in the industrial field, and its main function is to continuously record the voltage, current and other signals collected from the equipment for a period of time. Due to the design limitation of the oscilloscope, it is not possible to save the waveform to the memory while continuously recording the waveform. Therefore, before saving the waveform for further analysis, you must first press the "Stop\Start" function key of the oscilloscope to stop data acquisition, and then Executes the data save function. After all the data is saved, you can press the "Stop\Start" function key to start a new data collection. The problem is that when the oscilloscope is in the waveform acquisition state, pressing the "Stop\Start" button will make the oscilloscope enter the "stop state" to prepare ...

AI Technical Summary

Problems solved by technology

The problem is that when the oscilloscope is in the waveform acquisition state, pressing the "Stop\Start" button will make the oscilloscope enter the "stop state" to prepare for saving. However, during the on-site operation, operators often accidentally Press the "Stop\Start" function key twice, the oscilloscope will start from waveform acquisition - stop, the current waveform is displayed on the screen - enter waveform acquisition again, the previous waveform will be lost, and the waveform you want to save will be lost forever. Lost; if the acquisition is a repetitive waveform, it can be acquired again, if the acquisition is a non-repetitive waveform, the signal will be lost forever
