Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is workflow diagram of the present utility model.
Detailed description of the invention
Being illustrated in figure 1 the schematic diagram of automobile ABS-ECU Multi-parameter detection device of the present utility model, this device includes host computer 1, central controller 2, signal output module 3, signal acquisition module 4.Wherein, it is attached and communication by RS232 serial ports between host computer and central controller;Signal output module is realized by central controller controls D/A converting circuit, and is connected with the signal transducer in tested device A BS-ECU 17 by link terminal;Signal acquisition module is directly connected with the signal output pin of ABS-ECU, converted outputs signal to central controller.Understanding according to shown in above-mentioned detection project and Fig. 1, signal output module includes that trouble light signal output module 5, fault are dodged code signal output module 6, driven valve signal output module 7, wheel speed signal output module 8, key switch signal output module 9, brake switch signal output module 10.Signal acquisition module includes that trouble light signal acquisition module 11, fault are dodged code signal acquisition module 12, driven valve signal acquisition module 13, wheel velocity signal capturing module 14, key switch signal acquisition module 15 and brake switch signal acquisition module 16.
Host computer realizes detection purpose and selects, detect the transmission of project signal and show in real time.Central controller receives the signal sent by host computer, through judging and export corresponding detection purpose analogue signal, obtains the treated display in host computer of signal of ECU output subsequently.Trouble light, fault are dodged the signal output module such as code and are completed by D/A (D/A) change-over circuit.Trouble light, fault are dodged code modulating signal acquisition module and are completed by analog (A/D) change-over circuit.
Above-mentioned central controller is 32 ARM microcontroller STM32F103.
Work process of the present utility model is as in figure 2 it is shown, first read inside ABS-ECU after system electrification, and this ECU is the most qualified for preliminary judgement, if defective direct detection of end.Then select test item, successively carry out static state, dynamic test, additional testing and fault test according to the test item selected.After completing test, read and remove DTC.Finally, test data are carried out statistics form.
Detailed programs testing process is as follows:
1) trouble light/fault dodges code detection: host computer sends and opens, stops brake switch signal (1 road I/O controls relay), receives trouble light pin voltage signal, by the situation of change of trouble light leg signal, display DTC and information.
2) wheel speed Static Detection: host computer transmission frequency is at the 2 road voltage pulse signals (VSO, OBD, OC gate signal) of (0-2) KHz, it is achieved monitoring and the display to wheel speed output pin signal intensity situation.
3) wheel speed dynamically detects: host computer sends four-wheel wheel speed signal, brake switch signal, acceleration, add any interference wave signal, receive CAN signal and (include four-wheel wheel speed signal, brake switch signal), 8 map voltage analog signals, VSO, OBD, trouble light, electrode voltage current signal.
4) valve drives abnormality detection: carry out communication, control coil and electrical power situation between host computer and ABS-ECU product, receives 8 road voltage analog signals, 1 road motor voltage signal and 1 road motor current signal, and detection coil power supply and motor are powered.
5) K line/CAN line communication detection: host computer sends CAN protocol and K protocol signal, and carry out communication between ABS-ECU product, receive CAN protocol and K protocol signal, i.e. serial number, date of manufacture, software version, hardware version, date issued, system configurability breath, and show at human-computer interaction interface.
6) key switch abnormality detection: host computer sends switching key switch voltage analog signal (1 road I/O controls relay, 1 road A/D), receives 1 road voltage signal, thus realizes the control to product key switch break-make.
7) key switch abnormality detection.
8) brake switch abnormality detection: host computer sends switching brake switch signal, receives 1 road voltage signal, thus realizes the control to product brake switch break-make.
9) fault diagnosis detection: can manually arrange and realize with computer installation two ways.When manually arranging, by the break-make of the operation corresponding relay coil of on-off control, the contact of relay completes the operation such as the open circuit to simulated failure point, short circuit.Pressing a certain breakdown switch button, system can carry out corresponding fault simulation test;When computer is arranged automatically, the I/O port of measuring and controlling card send control signal, control corresponding relay through power driving circuit, it is achieved the function identical with Non-follow control, but computer can quickly complete identical task automatically.Meanwhile, relay, arranging fault when, has also been connected corresponding fault and has been arranged display lamp, the malfunction that prompting operator are current.
