Abstract
The utility model relates to a bus test system, which aims at no replacement of different lines during tests of different vehicles. The bus test system includes a table frame, test equipment, a center console, a computer, and test units, wherein at least two test units are mounted on the table frame, the center console is connected with the test equipment through the test units, and the test equipment is connected with the computer. In the system, one table frame can test buses of vehicles of various types, no connecting line for connecting each tested controller to the test equipment is required to be replaced when vehicles of different types are replaced, the test efficiency is improved, the connection error rate is reduced, and the development time of novel vehicle is shortened.
Description
Technical field
The utility model relates to automobile manufacturing field, and in particular, the utility model is the bus testing system that is used for electrical.
Background technology
At present, along with the fast development of automobile industry, the construction cycle of automobile requires shorter and shorter, so also more and more higher to the quality and the rate request of automotive system test.Real vehicle or body in white testing reliability high but very inconvenience and cost height when adopting yellow wooden handcart test, to different automobile types, need to change different wire harness, and load also will frequently be changed, and regulates also inconvenient.
Patent Office of the People's Republic of China has announced a CN201037807Y document on March 19th, 2008, name is called car engine electronic controller automatic checkout system, this system comprises control and processing module, data acquisition module and EMS-ECU interface system, data acquisition module is connected with the EMS-ECU controller by the EMS-ECU interface system, control sends control and acquisition instructions with processing module to data acquisition module, data acquisition module simulates the various signals under the various operating modes, EMS-ECU is worked under required operating mode, simultaneously, the supplemental characteristic that collection EMS-ECU works under corresponding operating mode and the control signal of output, feed back in control and the processing module, control is handled test data with processing module, computing judges whether the parameters of EMS-ECU under each operating mode is qualified.The shortcoming of this system is the requirement that can not adapt to the various vehicle tests of quick replacing, when vehicle changes, needs to change different wire harness.
Summary of the invention
The utility model provides a kind of bus testing system for solving the shortcoming that the test different automobile types need be changed different wire harness of working as that exists in the prior art, can adapt to the test of different automobile types.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model comprises stand, testing apparatus, console, computer, test cell, there are at least two test cells to be installed on the stand, console links to each other with test cell, described test cell links to each other with testing apparatus by bus, and testing apparatus links to each other with computer.The various test cells that are adapted to various different automobile types are installed on the stand, and be connected on the testing apparatus by bus, when needs are tested the controller ECU of a certain vehicle and bus, as long as all controllers that need test of this vehicle are connected on the corresponding test cell terminal box, can be communicated with load, actuator and bus, the fictitious load that can regulate tested controller by console changes; And the wire harness that does not need to change the actual use of this vehicle is built testboard bay again, does not need to reconnect fictitious load, sensor and actuator, has improved testing efficiency, has reduced the line error rate; On console, control the required fictitious load size of each test cell or the break-make of switching value during test, tested controller sends corresponding message according to coupled test cell variation on bus, testing apparatus is gathered the variation of message on the bus, and the result is shown on computers, stores.
As preferably, test cell comprises actuator, sensor, tested controller terminal box, is connected with console.Comprise the control of various fictitious loads and switching value on the console, can directly carry out the Physical layer test; Console links to each other with controller by tested controller terminal box, and actuator links to each other with controller by tested controller terminal box; Sensor is directly connected on the terminal box of tested controller, links to each other with controller to be measured by terminal box.Actuator also is to link to each other with controller to be measured by terminal box; When needs are tested the controller of a certain vehicle and bus, as long as all controllers that need test of this vehicle are connected with console, sensor, actuator and bus by the test cell terminal box, and the wire harness that does not need to change the actual use of this vehicle is built testboard bay again, do not need to reconnect fictitious load, sensor and actuator, improve testing efficiency, reduced the line error rate; Control the break-make or the size of the fictitious load of each test cell during test on console, tested controller sends corresponding message according to coupled test cell variation on bus.
As preferably, load is sensor or fictitious load.Same signal, sensor or fictitious load alternative.
As preferably, bus also is provided with terminal resistance and switch, and terminal resistance is connected with switch, and the series circuit of terminal resistance and switch is connected across the bus two ends by tested controller terminal box.When test contains the bus network of terminal resistance and ECU, can be according to required terminal resistance quantity of bus and the terminal resistance quantity that tested controller had, whether decision needs to increase terminal resistance; By terminal resistance of terminal box cross-over connection, terminal resistance is controlled by a switch, when a certain vehicle CAN bus of test, if existing two of the terminal resistance that all tested controllers had, then the terminal resistance complete resection on the stand; As two of less thaies, then supply two.
The beneficial effects of the utility model are: a stand can be tested the controller and the bus of multiple model automobile, when test automobile ECU of different model and bus and the wire harness that does not need to change the actual use of this vehicle is built testboard bay again, do not need to reconnect fictitious load, sensor and actuator, improve testing efficiency, reduced the line error rate.
Description of drawings
Fig. 1 is a kind of system chart of the utility model bus testing system.
Among the figure: 1. console, 2. actuator, 3. sensor, 4. tested controller terminal box, the 5. series circuit of terminal resistance and switch, 6. testing apparatus, 7. computer, 8. bus.
Embodiment
Embodiment:
The bus testing system of present embodiment, referring to Fig. 1, six tested controller terminal boxes 4 are installed on the stand, and each tested controller terminal box 4 all is connected with actuator 2, and sensor 3 all links to each other with console 1; Wherein there are four tested controller terminal boxes 4 that the series circuit 5 of terminal resistance and switch is not set, have the two ends of two tested controller terminal boxes 4 to be connected with the series circuit 5 of terminal resistance and switch; All tested controller terminal boxes 4 all are connected to testing apparatus 6 by bus 8, and testing apparatus 6 links to each other with computer 7.
During test, be connected on the tested controller terminal box 4 according to tested vehicle each tested controller tested automobile, according to how many decisions of the quantity of the terminal resistance that tested controller had whether the series circuit 5 of terminal resistance and switch is dropped into, always have two terminal resistances on the assurance bus 8; The fictitious load size in console 1 each load 3 of control or the break-make of sensor input, tested controller according to the fictitious load in the load 3 or or the break-make of sensor input change actuator 2 operated, also can directly carry out Physical layer test control on the console; The message that testing apparatus 6 sends each tested controller, record, parsing, and with sending computer 7 demonstrations as a result, storage.
