The monitoring sytem in the two levels were finished. The main controller of the system is OMRON CS1H-CPU65H PLC. The PLC controller was connected to three hoist slave stations via wired remote I/O bus, 16 OMRON temperature controllers via RS-485 bus and OMRON NT631C programmable terminals via RS232/RS422 bus,respectively.
In the secondary controller system, AT89S51 is chose for the main controller and the 5G14433 is chose for the A/D chip. AT89S51’s software includes controlling 5G14433, doing further disposal for the water signal, controlling the transmission network, incepting and executing the command from the host controller system.
On the basis of this, software and hardware of the separate station's measuring, controlling and communication system, in which use TI's single chip microprocessor MSP430F149 as the main controller, and use MOTOROLA'S G20 as the GPRS communication module, were designed and realized concretely.
In the intelligent remote terminal unit the high performance Digital Signal Processor ADSP-21065L is regarded as the controller, CAN bus is regarded as communications network to make up distributed system.
Secondly, basing on PROFIBUS technology, this thesis designed a hierarchical distributed control system for EDCS of 2730/500 Fourdrinier with Programmable Computer Controller (PCC) B&R 2005.Thirdly, aiming at the realization of EDCS, this thesis had done the following work.
a method of designing a simultaneous 4 axis control system is introduced in this paper, we use 8098 microcomputer as the main controls and combines the software with the hardware to realize high speed and high accuracy control for the motor by driven pulse.
A microcomputer control system with teaching interface which uses a 8098 Single Chip Microcomputer as its main controller was introduced in this paper. There five kinds of control methods for automatic acquisition were analyzed. The test of teaching control and automatic machining provided that this control system can raise productivity greatly and get a good economic efficently.
The digital control system with TMS 320 C25 digital signal processor as main controller is introduced. The hardware and software of this system are presented.
he principles of a main -Controller by the quasi -1b- bit single-chip microcomputer is described in this paper.We use it to control the UPS system,by the use of the quasi-synchronous method and the muiltiple-trapezoid integration algorithm.The emulation and experiment results are also given in the paper.
