Description
Technical field
The utility model is related to technical field of automatic control, more particularly to a kind of PID thermostatic control systems.
Background technology
Although the application of temperature control system all trades and professions at home is quite varied, from for temperature controller,
Overall development level is not still high, has larger gap compared with the advanced countries such as Japan, the U.S., Germany.At present, China is at this
Aspect general technical level is in middle and later periods the 1950's level, and matured product is mainly controlled with " point position " and routine
Based on PID controller.It can only adapt to general temperature system control, it is difficult to control delayed, complicated, time varying temperature system.And fit
The intellectuality of the higher control occasions of Ying Yu, Self Adaptive Control instrument, domestic technique be not also very ripe, forms commercialization and in instrument
In terms of the Self-tuning System of table control parameter, external existing more matured product.But as foreign technology maintains secrecy and China's exploitation work
The delayed Self-tuning System software for also not developing dependable performance that makees.Manually experience and field adjustable are true mostly for control parameter
Fixed, so manipulation is very not convenient.
Content of the invention
The utility model purpose provides a kind of PID thermostatic control systems, the deficiency for solving the above problems, it is achieved that automatically
Temperature control and manual temperature control double combination, are that control system is relatively reliable, operation more safety and stability.
The utility model is achieved in the following ways a kind of PID thermostatic control systems, main including intelligent controllable silicon
Heater, PLC control modules, PID controller, PLC control modules and PID controller are all filled with the heating of intelligent controllable silicon respectively
Connection is put, intelligent controllable silicon heater in closed cavity is provided with temperature sensor to sense closing in closed cavity
Temperature in cavity, temperature sensor one end are connected with PLC control modules by signal isolator a, then the other end passes through signal
Isolator b is connected to PID controller, and the signal that temperature sensor is sensed is transmitted by signal isolator a and signal isolator b respectively
To in corresponding controller；Ups power is connected with PLC control modules by PLC power modules, and PLC control modules are connected to external
Touch display screen, touch display is mainly used in displays temperature or work or the isoparametric display of trouble shooting, described
PLC is provided with failure detector, the external manual control equipment of described PID controller, do not work when PLC control modules or
When breaking down, manually control device is operated starting PID controller.
The beneficial effects of the utility model are simplified for design, and thermostatic control system adopts PLC and PID intelligence instrument two-ways
Control, improves the stability of permanent temperature control system, and in the case of improve control accuracy, also reduces cost of manufacture, realizes certainly
The dynamic mode of operation with manual double combination.

Control module（2）Connection, PLC control modules（2）It is connected to external touch display screen（10）, touch display screen（10）It is mainly used in
Displays temperature or work or the isoparametric display of trouble shooting, described PLC control modules（2）It is provided with failure detector
（11）, described PID controller（3）External manual control equipment（12）, when PLC control modules（2）Do not work or occur event
During barrier, manually control device（12）To start PID controller（3）It is operated.Job order：Ups power（9）Pass through
PLC power modules（8）Start PLC control modules（2）, PLC control modules（2）Start intelligent controllable silicon heater（1）In envelope
Closed chamber body（4）Interior heating, when temperature is raised, the temperature sensor arranged by inside（5）Temperature signal is passed through signal isolation
Device a（6）Feed back to PLC control modules（2）In, realize controlling intelligent controllable silicon heater（1）Work and work is each
Item parameter passes through touch display screen（10）Show, when PLC control modules（2）When breaking down, now failure detector
（11）Check that fault parameter is presented on touch display screen by failure（10）While display, artificial manually control device（12）
Start PID controller（3）, PID controller（3）The intelligent controllable silicon heater of control（1）Continue heating, having reached can be with
Keep in repair the effect while working on.
