Embodiment
See also Fig. 1, the first embodiment of the application's vehicle harness fault generator comprises:
Described instruction is divided into following two classes:
The first kind, the simulation short trouble.For example make circuit 1,2 short circuits, or make circuit 1,2,3 short circuits together, or make circuit 1,2 short circuits make simultaneously circuit 5,6 short circuits.
Equations of The Second Kind, the simulation open fault.For example make circuit 4 open circuits, or circuit 7,8 is opened a way simultaneously.
In an instruction, can both simulate short trouble, also simulate open fault.
A plurality of actuators 30 for example adopt relay.The control of the control level that actuator 30 controlled devices 20 are exported and open or close.
That is, the wire harness with n root circuit needs to arrange n* (n+1)/2 actuator 30 altogether, is triangle number just.This is optimum the setting, and the quantity of actuator 30 also can arrange greater than this optimum, has the unnecessary actuator 30 of carrying out identical function this moment.
Comprise 8 circuits as example so that single line is intrafascicular, the setting of actuator 30 as shown in Figure 4, corresponding actuator 30 of each small circle wherein.With the horizontal line of root circuit and ordinate infall be simulation open circuit actuator, the horizontal line of different circuits and ordinate infall be to simulate the short circuit actuator.Obviously, the horizontal line of circuit 1 has a place to intersect with the ordinate of circuit 2, and the horizontal line of circuit 2 has again a place to intersect with the ordinate of circuit 1, and this two places intersection only need to arrange an actuator 30 and get final product.
Preferably, described actuator 30 is comprised of triode and the relay of series connection.The control level driving force that controller 30 is exported is very weak, after amplifying through triode, can be used for driving the keying of relay.
Touch-screen 40 is on the one hand as command input device, on the other hand as display device.
