Design on Temperature and humidity
in a Automatic Control System
Abstract:This system is a temperature to pass single a machine control, realizes to the warehouse degree of humidity to proceed the auto control.System with LINGYANG SPCE061A single a machine for foundation, pass the arithmetic figure and imitate the type spreads to feel the machine proceeds the examination with the degree of humidity to the temperature;Correspondence function that make use of single a machine, adopt the RS-485 correspondence method proceed the network delivers the information.
The system designs a lord controls the machine of PC( since place of honor machine) passes the RS232 converts with RS485 the machine, realize to the management of many statureses system with control, the tiny function in control in lord realizes to proceed to the each statures system the solid hour supervises and control, and pass the SPCE061A editor control software to proceed the control to each numerator system.
The each statures system has to the machine that spreading and feeling the information proceeding sends out to handle;Keyboard, show to handle;Drive the air condition machine and go to the wet machine;Receive with send out the information place of honor machine etc. function, can realize to be the temperature degree of humidity beyond the reach of initial value, the single a function sends out to control the information automatically, driving the air condition machine and go to the wet machine, waiting the function.
Because the temperature controls with the degree of humidity the system is a per rank inertial system after the pure characteristic after having the obvious;Pass the control calculate way that study the system, decide to adopt the PID control calculate way, the calculate way's construction is simple, the technique is mature also good control function.
