[background technology]
In chemical industries such as coating, pigment, ink, mill base, dyestuffs, it is ground on liquid and solid liquid phase mixed material
With scattered field.The widely used speed control of traditional grinding, grinds because material must operate under certain speed, past
After being added up toward speed, grinding effect reaches, but energy consumption is exceeded, if speed does not have the material time made to surpass up
It is long, influence production capacity.Therefore, if by sand mill power limitation control system power mode of operation can be selected on the touchscreen, then
The power that machine needs to grind is set, carries out PID calculating to realize power limitation control using PLC, to realize energy-conservation, will have
Very important meaning.
[utility model content]
The purpose of this utility model seeks to solve above-mentioned deficiency and provide a kind of sand mill power limitation control system, if
Meter is reasonable, easy to operate, substantially increases security of system and reliability, especially with the obvious advantage in terms of energy-conservation.
A kind of sand mill power limitation control system, including PLC1, touch-screen 3, frequency converter 2 are designed to achieve the above object,
Connected between the PLC1 and touch-screen 3 using ethernet communication, profibus buses are used between the PLC1 and frequency converter 2
Communication connection.
Touch key-press area 4, viewing area 5 and power setting area 6 are provided with the touch-screen 3, the touch key-press area 4 is wrapped
The touch key-press on panel and panel is included, the touch key-press touches IC by passage connection, and the viewing area 5 includes grinding
Power viewing area, grinding rate viewing area.
The touch key-press area 4, viewing area 5, power setting area 6 connect touch sensing unit 7, the touch sensible respectively
Unit 7 is connected with display unit 8, and the touch sensing unit 7 is used to sense to be provided with touch signal, the display unit 8
Pressure sensitive unit.
The PLC1 is S7-300 series of PLC.
The utility model compared with the existing technology, so by S7-300PLC, TP1200 touch-screen, ABB ACS5500 frequency conversions
The electrical equipments such as device are constituted, wherein, S7-300PLC is mainly the rate signal and power signal of collection frequency converter, then basis
The performance number set on touch-screen carries out PID arithmetic to realize power limitation control, and TP1200 touch-screens are mainly realized for client
Human-computer dialogue, allows client to be free to selection Power Control and speed control, it is possible to required for setting on the touchscreen
Grinding power realizes optimal grinding effect, can also easily see real-time grinding power value and speed on the touchscreen
Value, the speed of the Power auto-adjustment motor that the ABB ACS5500 frequency converters can be set according to client realizes actual work(
Rate a small range fluctuation at setting performance number, so as to save energy consumption, the sand mill power limitation control system for client's grinding material
System is reasonable in design, easy to operate, substantially increases security of system and reliability, especially with the obvious advantage in terms of energy-conservation, is worth pushing away
Wide application.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the theory diagram of touch-screen in the utility model；
In figure：1st, PLC 2, frequency converter 3, touch-screen 4, touch key-press area 5, viewing area 6, power setting area 7, touch
Touch sensing unit 8, display unit.
[embodiment]
Further explained below is made to the utility model below in conjunction with the accompanying drawings：
As shown in Figure 1, the utility model includes：PLC1, touch-screen 3, frequency converter 2, are used between PLC1 and touch-screen 3
Ethernet communication is connected, and is connected between PLC1 and frequency converter 2 using profibus bus communications, and the PLC1 is S7-300 series
PLC。
As shown in Figure 2, touch key-press area 4, viewing area 5 and power setting area 6, touch key-press are provided with touch-screen 3
Area 4 includes the touch key-press on panel and panel, and touch key-press touches IC by passage connection, and viewing area 5 includes grinding work(
Rate viewing area, grinding rate viewing area, touch key-press area 4, viewing area 5, power setting area 6 connect touch sensing unit 7 respectively,
Touch sensing unit 7 is connected with display unit 8, and touch sensing unit 7 is used to sense to be provided with touch signal, display unit 8
Pressure sensitive unit.
The utility model uses Siemens S7-314PLC, Siemens's TP1200 touch-screens and ABB-ACS550 frequency converters, its
Middle PLC and touch-screen use ethernet communication, and PLC and frequency converter use profibus bus communications.Master is made on the touchscreen
Machine mode of operation selects text button, and mode of operation has speed control mode and power control mode, can select to need by it
The mode of operation wanted；Power setting domain is made on the touchscreen in addition, so as to set the power needed according to grinding technics
Value.When selection power control mode, the current power progress that PLC reads to come according to the power set on touch-screen and from frequency converter
PID arithmetic, allows the power of main frame to be fluctuated up and down in setting range, if actual power can rise automatically less than setting power
At high speed, it is allowed close to setting power, if actual power can reduce speed automatically, to be close to higher than setting power
Power is set, power limitation control is reached, so as to reach more excellent grinding material.
The utility model is simultaneously not limited to the embodiments described above limitation, other any real without departing from spirit of the present utility model
Matter and the change made under principle, modification, replacement, combine, simplify, should be equivalent substitute mode, be included in this practicality
Within new protection domain.
