Railway disaster prevention monitoring system
In response to the design requirements for railway safety and disaster prevention and monitoring systems, this program uses Nanda's proud extension NA400 redundant PLC. The main and slave PLC systems are respectively equipped with three serial communication modules, each of which is equipped with an air volume sensor, a rain sensor, and a snow sensor. Communication, according to the needs of customers such as the need for other access, such as seismic signals can also expand the serial communication module.
Coal Mine Integrated Automation System
The comprehensive automatic system of coal mines is a centralized monitoring of various relevant parameters or conditions for the safety and normal production of coal mines, and control of related links is an important facility for the safe operation of major production processes such as mining, transportation, ventilation, and drainage. The system includes monitoring of mine environment safety and monitoring of mine production (and equipment conditions, etc.), mine environmental safety monitoring is used to monitor downhole environmental factors that affect production safety and safety of mine workers, and mine production monitoring system is used to monitor the main equipment of coal production. Working conditions.
Hydropower station monitoring system
NTU's proud extension NA400 PLC has unique features for the power industry. The resolution of the SOE module is 1ms.
Accurate time recording, reliable performance; backplane comes with GPS time interface, no software, hardware configuration, the system automatically finished
Paired function, simple and practical; CMM401 serial communication module, can expand 4 or 8 RS232 serial ports, each serial port supports C language custom programming, easy to use, and the CPU exchange data using fieldbus, data exchange speed, operation simple.
Boiler and Auxiliary Control System
The control system of the whole boiler is adopted as the control system of the whole boiler, and the control system of circulating water of the hot water boiler and the flow control of the make-up water, the negative pressure control of the furnace, and the temperature control of the outlet water are implemented. It is convenient and flexible to choose the best control parameters and the best control scheme so that the entire boiler production process is in the best operating condition.
Sewage treatment automatic control system
The system selects NA400 PLC of NTU to control the decentralization of production equipments in each process section, and uses industrial Ethernet and modbus RTU to form a network. The upper computer is set up in the control room and central control room of each process section to build a human-machine interface.
