Distributed process control system training device

The tr--ning device consists of two parts of the hardware and software. Among them, the hardware includes the unit, the smart instrument, and the DCS control unit; Composition of engineering mathematics software.

Signal interface panel: The instrument signal and electrical signal in the control object are transferred to the signal wiring board, which provides sensor detection and actuator control signal interfaces such as *, AO, DO, etc., facilitating the connection to form a different control system. Different wiring between the experimental board and the signal board is performed through a secure -type plug -in wire to complete various experiments in the process.

System networks are divided into three levels: monitoring network, system network and control network. Monitoring network layers to realize the interconnection of engineer stations, operator stations, ** computing stations and system servers. Company, control the network layer to realize the communication station and the process of on -site control stations and processes.

Second, configuration and function

(1) The overall structure of the system

1. The system network architecture is composed of the management network (MNET), system network (SNET), and control network (CNET). The management network is an optional network layer, which is used to communicate with factory -level production management systems such as MES and third -party management software. It can also implement security information publishing through Internet, and realize data management and sharing.

2. System network connection engineer stations, operator stations, historical stations and control stations and other system nodes, support P-TO-P (peer network), C/S (client/server), P-TO-P and C /S (mixed) three network structures can quickly build a high -speed redundant network of star, ring or bus -type topology, complies with IEEE802.3 and IEEE802.3U standards, and 100/1000Mbps adapt.

3. The controller used by the control network for the control station is connected to each I/O module and smart devices. It supports the star and bus structure, which is in line with IEC61158 (national standard: JB/T10308.3-2001, European standard: EN50170) , Ensure the real -time, stability, and fast of on -site communication.

The comprehensive experimental system of power automation and relay protection is a highly automated multi -functional test platform. It can use teaching experiments to open multiple electrical engineering courses. Multiple sets of tr--ning systems can also form a complex power network system for comprehensive experiments. The tr--ning, which is a comprehensive monitoring of the power network by the power automation monitoring system, can also form any digital intelligent substation structure.

 

The device entrance is equipped with a leakage protector.

 

The entire experimental system control power supply (including relay auxiliary voltage) uses a DC 24V power supply within a safe voltage. The experimental signal requirements are required to output in accordance with the second standard of the power system, and the output power is strictly controlled to prevent hidden dangers of electric shock.
