Embodiment
Below in conjunction with Figure of description technical scheme of the present invention is done further explain.
The electric connecting relation of new-energy automobile off-line test utility appliance and car load is as shown in Figure 1.Utility appliance is obtained the 12V power supply from diagnose interface, and inserts car load CAN network herein.Power module in the utility appliance converts the 12V direct supply into the 5V direct supply and offers core controller module and LCD display module; The CAN communication module passes to the core controller module in the information that receives car load CAN network and after accomplishing the level signal conversion through data line, and the core controller module is carried out information interaction through parallel data line and LCD display module.
Master controller is connected through signal wire with touch LCD display, and master controller is connected from diagnostics port through wire harness with car load.Master controller is responsible for communicating with car load, according to set detection step, in conjunction with the current ongoing test item of car load, will be used for the information that the pilot operationp personnel operate and pass to LCD display; The information that LCD display is responsible for master controller is provided is carried out visualization display.
The step that master controller detects the new-energy automobile function comprises initialization, selection vehicle, communication, the current system state of judgement, selects information and display result six major parts.Testing process is as shown in Figure 2.
New-energy automobile off-line test utility appliance workflow disclosed by the invention is following:
(1) off-line test utility appliance initialization
Master controller begins to carry out initialization after the equipment energising, initialization procedure comprises the initialization of LCD display state and communication interface state.
(2) off-line test utility appliance operation designated program
After equipment is accomplished initialization, start corresponding off-line test program, start-up routine application interface automatically.
(3) wait for that the user selects vehicle
In the program interface, wait for LCD display induction user select the vehicle that will detect, and the positional information of sensing passed to core controller.
(4) confirm the selected vehicle of user
Core controller is translated into corresponding vehicle according to resulting positional information, and shows that to the user selected vehicle picture wait user confirms through MESSAGEBOX.
(5) select communication protocol
According to the vehicle that the user confirmed, it is subsequent use that core controller is selected corresponding with it communication protocol.
