Problems solved by technology
[0003] The purpose of the present invention is to provide a kind of wireless car special-purpose oscilloscope for the defect that the working mode existing in the use of the existing car special-purpose oscilloscope is inconvenient and flexible. The devices that realize the oscilloscope display function are separated, that is, the data acquisition system is separated from the oscilloscope host system. The data acquisition system and the oscilloscope host system each include a wireless communication module and are paired with each other. The data acquisition system and the oscilloscope host system are realized through the wireless communication module. Data exchange and transmission

A wireless vehicle specific oscilloscope, it aims at the existing vehicle specific oscilloscopes limitation, such as the usage work mode being not convenient enough and flexible, so it changes the structure of the traditional oscilloscope, to achieve the separation of the data acquisition and processing functions device and the oscillographic display device, that is, separating the oscillographic host machine and the data acquisition box, and the said oscillographic host machine and the data acquisition box respectively have wireless communication module with mutual matching, and through wireless communication modules, the both achieve data exchange and transmission, and after the data acquisition box connecting with the vehicle test point, the measured signals are transmitted to the oscillographic host machine after processed through wireless transmission mode, so the work range of the oscillographic host machine is no longer limited by the test line length and the connecting mode for expansion, and the operator can choose a more convenient and comfortable work place for fault testing and analysis, so that the work mode of the operator is more convenient and flexible.
Description
Technical field [0001] The invention relates to an oscilloscope for waveform display when maintaining a car, in particular to a wireless special oscilloscope for car maintenance. Background technique [0002] Oscilloscope technology is applied to the automobile maintenance industry, which can greatly improve the speed and accuracy of automobile fault diagnosis. The automobile special oscilloscope can provide high-performance diagnosis for various digital and analog signals of automobiles, and has the ability to capture waveforms instantly, real-time engine Ignition waveform analysis and powerful analysis and test functions, when some faults occur in the vehicle, especially when the car engine is running at high speed, due to the high sampling frequency of the car-specific oscilloscope, every important detail of the signal will be displayed, so that other routines can be identified Diagnose the fault signal that the equipment cannot recognize, and ass...
