Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of a kind of temperature-sensitive industrial ceiling fan based on touch screen and PLC of the present utility model;
The implication of reference character in figure: 1 temperature transducer, 2 touch screens, 3PLC, 4 frequency variators, 5 motors, 6 encoders, 7 impeller assemblies.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
As shown in Figure 1, a kind of temperature-sensitive industrial ceiling fan based on touch screen and PLC, comprises temperature transducer 1, touch screen 2, PLC3, frequency variator 4, motor 5, encoder 6 and impeller assembly 7.The output of temperature transducer 1 is connected with PLC3.PLC3 is connected with touch screen 2 by serial port communication line, and preferably, touch screen is connected with the PORT port of PLC by serial port communication line RS-485.PLC3 is connected with frequency variator 4, and frequency variator 4 is connected with motor 5, and motor 5 is connected with impeller assembly 7 with encoder 6, and encoder 6 feedback links are in PLC simultaneously.Encoder is analyzed motor rotate speed feedback to PLC, use pid algorithm, forms feedback control circuit.Encoder is incremental optical-electricity encoder, and its output is high-speed pulse.Touch screen is TPC7062K.The PLC of the S7-200 of PLCShi Siemens series.PLC inside can adopt high-speed counter to read the pulse of reading in from I mouth.The model adopting is E4036-50-3-T-24.
On touch screen, select ceiling fan rotating speed control mode, i.e. temperature transducer automatic control mode and touch screen manual control mode.Touch screen Configuration Design is mainly divided into welcomes the system that enters, main menu, systemic-function introduction, manual control interface, analog amount to control interface, observation interface, thanks and use seven parts.
System energising i.e. " beginning " enters system, and native system can be selected the mode of controlling on touch screen, and manually control or temperature transducer are controlled automatically.On touch screen, select control mode to click corresponding touching button, system determines whether that touch screen manually controls, touch the button " manually controlling ", and system is judged as manual control, enters the manual control mode of touch screen.
When touch screen is manually controlled, operation user can set the rotating speed of required ceiling fan on touch screen, ceiling fan start by set date or the parameters such as time that stop, and the while can show actual speed, the gear of ceiling fan.PLC forms closed loop control system by system.Operation user can write by RS485/PPI downloading wire the trapezoid figure program of finishing in PLC, and MCGS configuration program is write in touch screen by USB downloading wire, and touch screen is communicated by letter with the RS485 telecommunication cable that passes through of PLC.By touch screen, set ceiling fan running rotating speed and gear to PLC, thereby by the program operating voltage output signal of PLC, to frequency variator, control motor again, motor is by being in transmission connection and controlling ceiling fan rotating speed with impeller assembly, then adopt feedback elements incremental optical-electricity encoder measure motor speed and high-speed pulse signal feed back to PLC, PLC passes through inner resume module outputting analog signal to frequency variator, thereby frequency variator changes the rotating speed that the frequency of out-put supply changes motor, thereby control ceiling fan rotating speed.Incremental optical-electricity encoder measure the rotating speed of motor and as system feedback value to PLC, by closed loop PID regulate can be rapidly by the stabilization of speed of ceiling fan in setting value.
While adopting temperature transducer automatically to control, the time that can set ceiling fan start by set date or stop by touch screen equally, and show the actual ceiling fan rotating speed recording.Temperature transducer analogue signal corresponding to measured temperature value converts to and sends PLC to, thereby by the program operating voltage output signal of PLC, to frequency variator, control motor again, motor is by being in transmission connection and controlling ceiling fan rotating speed with impeller assembly, then adopt feedback elements incremental optical-electricity encoder measure motor speed and high-speed pulse signal feed back to PLC, system is formed to closed loop control system.
PLC carries out PID adjusting in interrupt routine, the setting value that the analogue signal input of the digital signal input on touch screen or temperature transducer is controlled as PID.Value after simultaneously PID being regulated converts corresponding analog amount to and exports to frequency variator, and frequency variator is by outside terminal acknowledge(ment) signal and realize the frequency control of motor speed of ceiling fan.The actual speed that system adopts incremental optical-electricity encoder to record feeds back to PLC, value of feedback using this value as system in PLC program also compares with setting value, system judges whether actual speed is setting value, if and setting value equates, ceiling fan stable and normally operation, if not etc., the deviation that system PID controls exists, and proceeds PID and regulates until ceiling fan is stable.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
