Parameter is tried, needing to be distributed totally 108 thermocouples, foil gauge on product, as sensor, thermocouple signal send U.S. FLUKE public
The temperature data acquisition instrument of department, foil gauge signal are sent into the data acquisition instrument of HBM company, Germany.Temperature data acquisition instrument
There is 3 tunnels totally 60 channel, 60 thermocouple signals: the 20 channels/road road x3=60 channels can be collected.Strain data acquisition instrument has
3 tunnels totally 48 channel, can collect 48 foil gauge signals: the 16 channels/road road x3=48 channels.Turn-key system passes through respectively
The Ethernet interface progress Industrial Ethernet communication of FLUKE temperature data acquisition instrument, HBM data acquisition instrument, acquires with data
Instrument is communicated, temperature collection, strain signal.But due to CPU and FLUKE the temperature data acquisition instrument CPU of main control PLC and
The clock of HBM data acquisition instrument CPU is different, therefore, causes the collected temperature of turn-key system, strain signal asynchronous, right
The hot Combined Loading temperature of power, strain data test and analyze asynchronous, structural strength to component and mechanical behavior analysis cause
Error.Especially under high frequency, the data acquisition instrument of temperature data acquisition instrument and foil gauge signal is extremely difficult to same
Step.Therefore, it is necessary to synchronize processing using software in main control PLC CPU, treatment process is very complicated, and temperature data acquisition
The cost of the data acquisition instrument of instrument and foil gauge signal is very high, and there are costs for the existing hot Combined Loading device systems of power
Height, the problem of synchronously control hardly possible.And since FLUKE temperature data acquisition instrument CPU and HBM data acquisition instrument hardware is limited,
Do not have the extension testing requirement of thermocouple and foil gauge.
Utility model content
The purpose of this utility model is to provide a kind of hot Combined Loading device data synchronous control systems of power, for solving
In the prior art in the hot Combined Loading system of power FLUKE temperature data acquisition instrument CPU and HBM data acquisition instrument CPU when
Clock is different, causes the collected temperature of turn-key system, strain signal asynchronous, surveys to the hot Combined Loading temperature of power, strain data
Try and analyze asynchronous, the problem of structural strength to component and mechanical behavior analysis cause error.
The utility model is solved the above problems by following technical proposals:
A kind of hot Combined Loading device data synchronous control system of power, including industrial control computer further include calculating with industry control
