Trend of work, simulation effect it is good;
(2) the utility model realizes the lever progress to gear shifting device by the proximity switch being arranged on each gear
Put into gear the real-time monitoring of action, for mechanical touching switch, with proximity switch to the collection of gear information more
It is sensitive and accurate, external condition interference is not easily susceptible to, the real-time Simulation to put into gear action and the gear shifting action of gear shifting device is realized;
(3) the utility model on base by setting cover body so that simulator is not easily susceptible to when carrying out in-site modeling
External interference, it is ensured that the job safety of Field Force;It is illuminated simultaneously by LED light bar, it is ensured that high-speed industrial camera
The definition of shooting, so that industrial computer carries out picture processing.
