Description
Technical field
The utility model relates to the power supplies of the engine of power assembly testing field more particularly to power assembly engine bench test to be
System.
Background technique
In Full Vehicle System, the control of automobile current supply circuit is mainly realized by key switch.When engine from
It is disassembled on vehicle when being put into laboratory, the requirement of experiment is obviously not achieved by key controller.In order to test

System.
Utility model content
Technical problem to be solved in the utility model is to realize that a kind of engine for power assembly engine bench test supplies
Electric system.
To achieve the goals above, the technical solution adopted in the utility model is：One kind being used for power assembly engine bench test
Engine power supply system, the engine power interface of power assembly rack is separately connected spreadsheet engine to be measured there are three setting
Igniting, starter motor, oil pump function power interface, system are equipped with PLC and three relay, and the output end loop of relay K1 connects
Positive pole and priming supply interface, the output end loop connection positive pole and starter motor power interface of relay K2, relay
The output end loop connection positive pole and oil pump function power interface of device K3, the input end loop connection of the relay K1
The ignition signal output and ground of PLC, the starter motor signal output end of the input end loop connection PLC of the relay K2
And ground terminal, the oil pump function signal output and ground of the input end loop connection PLC of the relay K3.
The PLC power supply interface connects power-supply device, ignition signal input terminal and oil pump the function signal input of the PLC
End connects power-supply device through key switch.
Fuse is equipped between the key switch and power-supply device.
Fuse is equipped between the output end loop and positive pole of three relays.
The plc communication interface is connected with human-computer interaction device.
The utility model has the advantage of the harness seamless interfacings for making pedestal control system and power assembly system, so that
The power supply system of experiment realizes to automatically control and be possibly realized that system is higher and easy to implement by PLC control stability, reduces
Control cost.
Detailed description of the invention
The content of width attached drawing every in the utility model specification expression is briefly described below：
Fig. 1 is the control section PLC circuit diagram；
Fig. 2 is the interface section circuit diagram of rack and power assembly harness.
Specific embodiment
There are three the engine power interface of power assembly rack is set, it is separately connected igniting, the starting of spreadsheet engine to be measured
Machine, oil pump function power interface, this technology are the control function using PLC, realize manual operation and process control
Perfect combination.
For the engine power supply system of power assembly engine bench test, PLC and three relay, as shown in Fig. 2, relay
The output end loop connection positive pole and priming supply interface of K1, the output end loop of relay K2 connect positive pole and open
Motivation power interface, the output end loop connection positive pole and oil pump function power interface of relay K3, positive pole provide
12V voltage, is powered by automobile batteries, fuse can be arranged between the output end loop and positive pole of three relays, be kept away
Exempt to occur for electric short circuit.
As shown in Figure 1, the ignition signal output and ground of the input end loop connection PLC of relay K1, relay
The starter motor signal output end and ground terminal of the input end loop connection PLC of K2, the input end loop connection PLC's of relay K3
Oil pump function signal output and ground, PLC power supply interface connect power-supply device, and power-supply device provides 24V voltage, and PLC is logical
Letter interface is connected with human-computer interaction device.The output loop of PLC in this way drives relay, we can pass through the touching of relay in turn
Point realization is docked with power assembly harness, realizes igniting, the normal operating of starter motor, oil pump function.
In order to can be realized handcar operating function simultaneously, PLC power supply interface connects power-supply device, the igniting of the PLC
Signal input part connects power-supply device through key switch with oil pump function signal input terminal, can both pass through the simulation key of vehicle in this way
Spoon switch can realize the power supply and start-up operation of power assembly to be manually operated by touch screen, and key switch is to PLC's
Input circuit has short-circuit protection function, prevents the input module for burning out PLC.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implements not by above-mentioned
The limitation of mode, as long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or not
It is improved the conception and technical scheme of the invention are directly applied to other occasions, the protection scope of the utility model it
It is interior.
