Technical field
The present invention relates to a kind of automobile combination instrument test register system.
Background technology
At present, automobile combination instrument test pen recorder be a kind of auxiliary research staff in the design R&D process of automobile combination meter, the device that the function to combination instrument and the test process of performance record.Research staff, by observing the record in combination instrument test process, analyzes the design defect of combination instrument and is improved.
Traditional automobile combination instrument test pen recorder, records by means such as range estimation, paper pens the phenomenon that automobile combination meter presents in test process by tester often.This method of testing often too gets sth into one's head, efficiency and precision is low, to record content single, be unfavorable for that research staff finds the design defect of automobile combination meter veritably, and the data of traditional method record is unfavorable for preserving.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of automobile combination instrument test register system.
The present invention for achieving the above object, adopt following technical scheme: a kind of automobile combination instrument test register system, it is characterized in that, comprise main control board, digital camera and travel(l)ing rest, described main control board is connected with digital camera by usb interface module; Described digital camera is arranged on travel(l)ing rest, and can adjust arbitrarily shooting angle with respect to the movable end of described travel(l)ing rest; Described main control board is by external power source module for power supply; Wherein, described main control board comprises MIPS main control chip, TFT color screen liquid crystal display, memory module and independent button, and the first communication terminal of described MIPS main control chip is connected with described usb interface module, and the second communication terminal is connected with described memory module; The input end of described MIPS main control chip is connected with described independent button, and output terminal is connected with described TFT color screen liquid crystal display.
Further, described memory module is SD storage card.
Further, described external power source module is the vehicle power unit with automobile charger interface, and it is connected with described MIPS main control chip by power interface.
Further, described independent button comprises that system starts button and video monitor button.
Beneficial effect of the present invention: camera shooting angle of the present invention is flexible, simple and quick, camera can record all phenomenons and the data of automobile combination meter in tested process clearly and completely, and function and the performance of reasonably analyzing exploitation automobile combination meter to research and development designer are brought important reference value.In addition, the video data of camera collection can directly be stored in the SD storage card arranging on main control board, video data is difficult for losing like this, and reads conveniently, and the video information being stored in SD storage card can directly show by TFT color screen liquid crystal display.
Accompanying drawing explanation
