Description of drawings
Fig. 1 is a system chart of the present utility model.
Fig. 2 carries out automatically controlled circuit diagram to the stand fan among the utility model embodiment one.
Embodiment
Below with reference to accompanying drawing, comparatively detailed explanation is carried out in each preferred embodiment of the present invention.
Embodiment one: the software of present embodiment utilization is to develop on the business software PUMA basis that provides of Austrian AVL company, the function major control threst stand of PUMA, by electric dynamometer control engine speed, torque etc., in engine operation process, measure each parameter of engine, and each parameter shown and analyze, finish automatic control to the stand subsystem.PUMA also has the communication interface with testing apparatus in addition, by communicating with testing apparatus testing apparatus is controlled automatically.In test process, can pass in the control system by stand itself each parameter of measuring engine in the engine operation process, as temperature, pressure etc., control system is by the analysis to these signals, as temperature signal when too high, control electric fan or air-conditioning are finished the automatic control to stand utility appliance subsystem to environment temperature reduction.As shown in Figure 1, a kind of automatic control system of car engine machine frame is installed on the stand control desk, comprises display operation system, stand autonomous control subsystem, testing apparatus autonomous control subsystem, also comprises the peripheral auxiliary equipment autonomous control subsystem.Stand autonomous control subsystem and stand link, accept the state parameter of stand output, and this parameter handled, utilize result that stand is controlled automatically, simultaneously, utilize the testing apparatus autonomous control subsystem that testing meter and instrument is operated and test result is fed back to control desk, control desk fully utilizes test result and from the order of operating system input the stand autonomous control subsystem is controlled, simultaneously, utilize the peripheral auxiliary equipment autonomous control subsystem of stand that the peripheral auxiliary equipment of stand is controlled automatically, such as recognize at control desk when testing that environment temperature is higher actually, can control electric fan on the stand to platform system cooling etc.
Embodiment two: the brightness to the stand environment is controlled automatically, when control desk knows that by sensor ambient light is more weak, by the controller output command, connect the input end and the 12V power supply of low-voltage relay, make the low-voltage relay adhesive, relay output end is effective, and operating voltage is added on the lamp.Because the voltage that electric light uses is generally the 220V operating voltage, generally can not cause damage to low-voltage relay, therefore directly control the power supply of electric light by relay.Conversely, when surround lighting is strong, can disconnect low-voltage relay and low-tension supply, low-voltage relay output is opened circuit, cut off the power supply of bulb by order.
Embodiment three: the temperature to the stand environment is controlled automatically, show as Fig. 2, described peripheral auxiliary equipment autonomous control subsystem comprises controller, the low-voltage control power 22 of low-voltage relay 2 and 12V, the high voltage control power supply 32 of 220V alternating current and high-voltage relay 3, controller is installed on the described stand control desk 1, there is a control output end mouth to connect with described low-voltage relay 2 and low-voltage control power 22, the output terminal of described low-voltage relay 2 is connected with the input end of high voltage control power supply 32 and high-voltage relay 3, electric fan 5 that the output termination of described high-voltage relay is controlled and the working power 4 of 380V.Its course of work is as follows:
Whether the signal input part at low-voltage relay 2 adds low-voltage relay power supply 22 by the input signal end that control desk 1 provides control signal to make low-voltage relay 2, here be the battery of 12V, control signal is connected in series between low-voltage relay two ends and 12V battery, if do not need electric fan 5 work, then control signal is a high resistant, low-voltage relay 2 input ends do not have electric current, low-voltage relay 2 not adhesives, need cooling if temperature is too high, then control desk 1 is exported a low-resistance signal, the input end of low-voltage relay 2 has electric current to flow through, low-voltage relay 2 adhesives.
Equally, when not needing electric fan 5 work, low-voltage relay 2 not adhesives, disconnected connecting of high-voltage relay 3 input ends and 220V power supply 32, the input end of high-voltage relay 3 does not have electric current to flow through, high-voltage relay 3 not adhesives have disconnected getting in touch of electric fan 5 and 380V working power 4, and electric fan 5 is not worked.When the too high needs of temperature were lowered the temperature, low-voltage relay 2 adhesives were added to high-voltage relay 3 input end both sides with the 220V power supply, make high-voltage relay 3 adhesives, connect the working power of electric fan 5 and 380V.
In a word, electric fan in the foregoing description and electric light automatic control circuit are an example, in fact have the peripheral auxiliary equipment of a lot of stands to control its work by controlling its power supply.As being the automatic control circuit of air-conditioning, utilize this circuit to control the power supply of air-conditioning.In a word, this circuit can be controlled the power supply of any utility appliance of stand and control its work, if the utility appliance of stand is intelligent, can also communicate by communications facility and present gantries automatic control system, to control this how utility appliance work.
