Description
Technical field:
The present invention relates to electricity field, relate in particular to the environmental test technology with the automobile instrument of CAN bus, particularly a kind of band CAN bus automobile instrument long duration test test macro.
Background technology:
In prior art, the automobile instrument product needed is carried out aging test, in aging test, allows instrument be in to be in the method for particular job mode to have following two kinds:
The first: instrument is arranged on to a specific pattern in process of the test always, only sends out message a small amount of and meet testing requirements.This mode can not meet the requirement of product design checking.
Second method: under normal conditions, drive instrument with the automobile instrument of CAN bus with CANoe or NETWAY, make it to enter mode of operation.CANoe and NETWAY instrument are very expensive, are all that several projects share kit usually.And the aging test process need continues 3 months, that is to say need to continue to take the CANoe instrument for 3 months, and this can have a strong impact on the utilization of resource and the exploitation of other project.And switching, the configuration of instrument between different mode is very inconvenient.
Summary of the invention:
The object of the present invention is to provide a kind of band CAN bus automobile instrument long duration test test macro, the described this technical matters that is difficult to share testing equipment with the automobile instrument of CAN bus that will solve in prior art with CAN bus automobile instrument long duration test test macro.
this band CAN bus automobile instrument long duration test test macro of the present invention, comprise a computing machine, USB (universal serial bus) and Controller Area Network BUS communication device, a loader and a direct supply, wherein, described USB (universal serial bus) and Controller Area Network BUS communication device adopt USB CAN II communication tool, USB CAN II communication tool comprises first serial communication interface and second serial communication interface, USB CAN II communication tool is connected with described computing machine by described the first serial communication interface, USB CAN II communication tool is connected with described loader by described the second serial communication interface, loader is connected with Controller Area Network BUS, described direct supply is connected with loader, automobile instrument to be measured is connected on Controller Area Network BUS, utilize described computing machine, by the time that sets in advance and pattern controlled loading device, the automobile instrument to be measured on Controller Area Network BUS is carried out to aging loading.
Further, utilize computing machine by batch, to read in the configuration information of configuration file, change control general ability area network bus, and carry out batch circulation transmission.
Principle of work of the present invention is: utilize computing machine and be connected to the loader communication on the CAN bus, control the operational factor on the CAN bus, in computing machine, pre-set the different mode configuration file, the operational mode of product can be switched arbitrarily in aging test.Different products only need to change configuration file and get final product.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention utilizes computing machine and is connected to the loader communication on the CAN bus, controls the operational factor on the CAN bus, in computing machine, pre-sets the different mode configuration file, and the operational mode of product can be switched arbitrarily in aging test.Different products only need to change configuration file and get final product.The present invention can improve testing efficiency, and the disparity items application file can be shared.Save the instrument cost of test, meet client's demand.
