Abstract:
This article main introduction reaches the mechanical and
electrical product on glass fiber reinforced plastic equipment
application. This case manifested to reach the product to save
the superiority which the equipment cost and the system entire closed.
Key word:
Man-machine contact surface MODBUS warm controlling frequency
changer glass fiber reinforced plastic
Foreword:
VGPM-0803 marching pulls the thumb ring to belong to the glass
fiber reinforced plastic to take shape the equipment one kind,
marching tows the way to pull for the machinery crowds. Tows the
speed continuously to be possible to adjust, the heating temperature
may move.
The early time marching pulls the thumb ring technology content
to be low, only depends on the warm controlling control heating
temperature, the speed is unable the accent. Causes starts to
pull the material time because the speed too quickly frequently to
pull. Not only operated the human nature, did not increase
personnel's labor intensity, moreover production efficiency low, the
production cost was high.
Based on the above shortcoming, produces the factory to have
reto develop the electrically controlled system, the initial plan is:
PC (configuration software) + PLC+ thermoelectricity pair module
+ frequency changer. Analyzes after our personnel:
Customer technological requirement quite simple, only requests
to the electrical machinery velocity modulation and the temperature
moves warm, the equipment field use environment is bad. Rehas
custom-made the plan is: HMI+ warm controlling + frequency
changer. Not only the plan simple, the implementation is
convenient, moreover reduced 50% cost for the customer.
First, system request
1st, 加热?automatically carries on the PID
adjustment to equipment 6, the error does not surpass 2.
2nd, controls the electrical machinery the start, stops.
The electrical machinery load start request start is steady,
3rd, can on the man-machine contact surface the
monitoring equipment current movement situation
4th, man-machine interfacial energy graphic display
device operation standard Second, system plan implementation
In view of customer request. Disposes as follows:
A57GSTD×1
DTA4848R1×6
VFD037M43×1
The man-machine uses MODBUS ASCII and warm controlling
and the frequency changer communication.
Reaches HMI, the frequency changer and warm control all supports
the MODBUS agreement, has provided the powerful technical support for
the product networking use.
Diagram as follows:
Third, man-machine page establishment
Fourth, summary
This case superiority does not lie in technical itself
(quite to be simple because of craft control), but lies in to reach
the mechanical and electrical conformity in the cost and the use
superiority.
