1. Overview The
Process Control System (PCS) simulates common physical quantities in modern industrial production processes, such as temperature, pressure, flow, liquid level and other parameters, to measure, control and analyze process parameters. Teaching experimental equipment for changing characteristics and studying process control laws (such as PID control). The process control comprehensive experimental device uses intelligent industrial instruments and meters, which are close to industrial reality, safe to use, stable in operation, simple to m*nt*n, and superior in cost performance. This device integrates multiple control methods.
1. Function:
(1), can meet the teaching and experimental needs of "automatic adjustment principle", "process control", "control instrument", "automatic detection technology and sensor ", "computer" and related courses;
(2), can It serves as an internship and tr*ning experimental equipment for relevant enterprise technicians, instrument operators, and system operation monitoring personnel.
2. Technical support:
Based on the PCS series of products, combined with new theories and methods in the field of control, the company will continuously develop and innovate experimental equipment and develop various advanced control algorithms to adapt to the reform of teaching experiments in colleges and universities and meet the needs of modern education development needs and promote development to a higher level.
The company advocates honest service and strives to provide customer service and technical support. Through intuitive and real experiments, students can comprehensively and systematically understand the characteristics of process control systems and learn to master the design and implementation methods of control systems.
2. Product structure and features:
Equipment features:
Experimental device: It is composed of a st*nless steel frame, a water tank, a separate heating boiler and st*nless steel pipes. The water supply system has one line: one line consists of magnetic pump, pressure instrument, electric regulating valve, solenoid valve, turbine flow meter, liquid level transmitter, pressure transmitter and manual regulating valve; single-phase electric heating pipe pipes and valves: the entire The system pipelines are connected by plastic-coated st*nless steel pipes, and all manual valves are made of high-quality ball valves, which effectively increases the service life of the experimental equipment.
3. Technical parameters and requirements:
1. Power supply
single-phase AC power: 220VAC±10%, 50Hz±5%, 16A. The system must be well grounded.
2. The laboratory should have water sources and inlets and dr*nage outlets. The distance between the inlet and outlet and the equipment is generally required to be less than 10 meters
3. The input and output signals of the system instruments comply with IEC standards
(1) Transmitter current source signal: 4-20mADC.
(2) Instrument sampling: 1-5V (250Ω)/0.2-1V (50Ω)
4. The system provides DC linear regulated power supply (Chaoyang Power Supply Products) 24VDC/1A.
5. The upper computer configuration software
uses MCGS (Monitor and Control Generated System) full Chinese industrial control configuration software to develop the experimental system. For operating environment requirements, see MCGS User Guide. It can form a network, and the teacher's computer can control more than a dozen student computers to achieve data sharing.
