The structural representation of the AuCT hardware in the loop test-rig that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the system of the present embodiment comprises: the first industrial computer 10 and peripheral circuit 20.
The first industrial computer 10, for building the emulation major loop of the primary work loop under the control of simulation AuCT, and the control signal of sending according to the controller 30 of AuCT is controlled emulation major loop, and the feedback signal of emulation major loop is offered to controller 30, to adjust the steering logic of controller 30.
Peripheral circuit 20 comprises a plurality of electronic circuits, and wherein each electronic circuit is connected with the corresponding plug of AuCT respectively.Whole peripheral circuit 20 is for building the working environment of controller 30.

Wherein, contactor analog submodule circuit 21 is connected with the plug X082 of controller 30 output contactor control signals, be used for receiving contactor control signal, and contactor analog submodule circuit 21 is also connected with the plug X080 that controller 30 receives contactor response signal (claiming again contactor feedback signal), for returning to contactor response signal to controller 30.Comparatively preferred, contactor analog submodule circuit 21 can be an electromagnetic relay, is connected between plug X082 and plug X080, with electromagnetic relay, carrys out simulating contact device.When controller 30 sends the control signal of control contactor closure or disconnection, electromagnetic relay disconnects accordingly or is closed, and by auxiliary contact, response signal is returned to controller 30.In addition, the first industrial computer 10 is also connected with contactor analog submodule circuit 21, for the contactor control signal of acquisition controller 30 outputs.
Wherein, when AuCT is normally worked, fuse, fan, transformer Overtemperature protection circuit should be all normal, also just say and on fuse, fan and the transformer Overtemperature protection circuit being connected with plug X081, have the input of normal working signal.In the present embodiment, by fuse analog submodule circuit 22, fan analog submodule circuit 23 and overtemperature prote analog submodule circuit 24 are connected in to plug X081, simulate the normal working signal of fuse, fan and transformer Overtemperature protection circuit respectively.Comparatively preferred, fuse analog submodule circuit 22, fan analog submodule circuit 23 and overtemperature prote analog submodule circuit 24 are respectively a normally closed push button switch, and the two ends of normally closed push button switch are connected to the two ends of plug X081.With normally closed push button switch, in closed condition, simulate normal operating conditions, with normally closed push button switch, in off-state, simulate the malfunction of fuse, fan and transformer Overtemperature protection circuit.
It is plug X371 and/or X372 for the feedback signal of the first industrial computer 10 outputs being sent into the analog input channel of AuCT that signal is adjusted electronic circuit 25.Because the signal amplitude of the first industrial computer output is conventionally between 0-5V, and the receptible signal amplitude scope of AuCT is-arrive+5V of 5V, therefore the amplitude that the present embodiment is adjusted 25 pairs of feedback signals of electronic circuit by signal is adjusted, be adjusted into the scope that AuCT can be identified, and then send into analog input channel.The input end that this signal is adjusted electronic circuit 25 is connected with the first industrial computer 10, and for receiving feedback signals, its output terminal is connected with analog input channel, the feedback signal after adjusting for output amplitude.The signal of the present embodiment is adjusted electronic circuit 25 except the amplitude of feedback signal is adjusted, and also can to feedback signal, adjust for the satisfied condition that is greater than 50 milliamperes (mA) of electric current of assurance part input channel.
