Description
Technical field
The utility model relates to a kind of portable vehicle bus test communication tool, belongs to a kind of bus communication test instrument to vehicle-mounted CAN, LIN, K network.
Background technology
CAN/LIN/K bus communication technology has obtained applying very widely in auto electric field at present, shelves respective bus communication test instrument, and as CANOE etc., although function is powerful, price is very expensive, conventionally all needs hundreds of thousands unit.For a lot of medium-sized and small enterprises, be difficult to this kind of bus test equipment in batches.
Summary of the invention
The purpose of this utility model is to provide a kind of portable vehicle bus test communication tool, and its volume is little, lightweight, and cost of manufacture is low, has bus data monitoring, bus data record, data readback, digital simulation sending function.
The technical solution of the utility model is achieved in that a kind of portable vehicle bus test communication tool, it is characterized in that: in test box, be fixed with testing host, host computer is by the bus interface on USB connecting line and testing host, MCU micro controller unit connects, bus interface is connected with Signals Transfer Board by CAN/LIN/K data bus, on Signals Transfer Board, have On-Board Diagnostics (OBD) interface, power interface, CAN/LIN/K bus monitoring interface, the power interface of MCU micro-control unit is connected with signal web joint by power lead, on test box, there is LED light, the driving circuit of LED light is connected with MCU micro controller unit by signal wire.
Good effect of the present utility model is that its volume is little, lightweight, has portable feature, and meanwhile, the hardware cost of a whole set of test macro is in 1000 yuan, and two test functions are relatively powerful, have higher practical value.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is testing process block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: a kind of portable vehicle bus test communication tool, it is characterized in that: in test box, be fixed with testing host, host computer is by the bus interface on USB connecting line and testing host, MCU micro controller unit connects, bus interface is connected with Signals Transfer Board by CAN/LIN/K data bus, on Signals Transfer Board, have On-Board Diagnostics (OBD) interface, power interface, CAN/LIN/K bus monitoring interface, the power interface of MCU micro-control unit is connected with signal web joint by power lead, on test box, there is LED light, the driving circuit of LED light is connected with MCU micro controller unit by signal wire.
The task that testing host is being born with host computer and communicated by letter, LED light on and off are received and dispatched and controlled to bus data; Signals Transfer Board is born the task of signal converting, and main four aspects connect: the one, be connected with testing host, and the 2nd, be connected with measured piece, the 3rd, be connected with power supply, the 4th, be connected with LED drive plate; On pilot lamp drive plate, be welded with LED and current-limiting resistance, the power supply of LED and control signal are attracted by 16pin winding displacement by Signals Transfer Board, and the led control signal on Signals Transfer Board is attracted by 34pin winding displacement by mainboard.
During test, tested exemplar is connected with the CAN/LIN/K bus monitoring interface of test box by data bus, and power supply is connected with the power interface of test box by power lead, and test box adopts 12V power supply, and feed circuit adopt the mode that supplies power with double circuit:
A), when carrying out real vehicle test, test box can be directly from the power taking of vehicle-mounted OBD mouth, and unwanted external power supply.
B) when carrying out desktop test, also with independent power supply interface.
The above-mentioned mode that supplies power with double circuit, has improved convenience and practicality that testing tool uses.
Between host computer and testing cassete, by USB interface, connect, when implementing bus test, upper computer software is responsible for sending instruction to slave computer testing cassete, and receives testing cassete and send the feedback information of returning, and bus communication data can show constantly in the respective window of upper computer software; Host computer is in the mode of " operation test case ", realization sends bus data to slave computer simulation, test routine is actually the file of an EXCEL form, in routine file, every a line represents a test command, when executive routine file, host computer is understood every a line test instruction in test routine, and sends bus command to slave computer testing cassete.
The test philosophy of system is:
Upper computer software is main control unit, and host computer read test use-case, by communication unit, sends to one by one from control unit, can be to sending various instructions from control unit, and receive the data of returning from control unit; Communication unit is realized the conversion of usb data and SPI data, reach main control unit and from control unit communication object.
Slave computer testing host from controlling unit according to the test instruction of upper computer software, is handled topworks and is realized system testing; Testing host receives test case or the instruction that main control unit sends, by instruction and data analysis, drive different performance elements, and measured piece is returned results and sends to main control unit, topworks comprises that bus data forwards and LED indication two parts, and topworks is connected with measured piece by Signals Transfer Board.
