Pass through foregoing description, it is clear that daily, monthly and the principle of annual related energy consumption and product information monitoring and
Hour be the same, i.e., such as Fig. 2, can also use be used to provide using day, the moon, year as measurement period register (284,285,
286) other registers of outfit identical as above-mentioned first time register 281 may be used, and each, it is no longer superfluous here
It states.
In specific implementation, human-computer interaction device 290 communicates RS485 modes with PLC technology use and is attached, and leads to
The establishment of program is crossed to whole system i.e. die casting machine servo system 10, energy consumption similarly hereinafter, yield, electric current, voltage, etc. carry out it is real-time
Display and monitoring, can carry out the setting of parameter and the control of system, human-computer interaction device 290 is encoded with parameter setting picture, can
Carry out process detection number of packages, process detection time are periodically examined without operation autostop time, oil tank cleaning reminder time, equipment
The setting functions such as reminder time, day shift work hours, night shift work hours, power saving rate, mutual inductor multiplying power are looked into, are provided significantly man-machine
The ability of data interaction, each numerical value load button is corresponding with the data register of programmable controller 270, such as human-computer interaction
290 process of device detection number of packages numerical value button corresponds to the data register D600 of programmable controller 270, programmable controller
270 carry out time control according to D600 numerical value, and setting process detection time arrives, and equipment is automatically stopped operation, and quality inspection personnel carries out
The examination and test of products.
In specific implementation, since servo-driver generates a large amount of higher hamonic wave at work, harmonic wave can be with electric current
Into in power grid, interference effect normal work is generated to other equipment, contaminated electricity is used for a long time in servo drive system 20
Source can reduce the rectifier bridge of servo drive system 20 and the service life of module.This is the filtering from the angle of harmonic wave
Device should use EMI power filter, and EMI power filter be made of filter capacitor, filter inductance and resistance, can improve and be
The power factor of system reduces the reactive power of system, filters out the higher hamonic wave of servo-driver generation, prevents servo to system
Interference.
In conclusion the present invention innovatively provide that a kind of energy consumption to die casting machine servo system 20 is monitored be
System, brings great convenience to produced on-site so that production management becomes intelligent.So the present invention effectively overcomes now
There is the various shortcoming in technology and has high industrial utilization.
