HF-NECM series communication manager

HF-NECM series communication manager, as the communication bridge between the substation and the master station, is mainly used for equipment protocol conversion of power station, which realizes the data acquisition and forwarding under different protocols to meet relevant standards and specifications of power security, and the transmission of data from the substation to the dispatching system at all levels or the group's unified monitoring platform of operation and maintenance so as to seamlessly connect the equipment of various brands of manufacturers. 

● With hardware independent watchdog circuit, software watchdog, monitoring and daemon process, etc.

● Support RS485, RS232, Ethernet, wireless 4G communication methods and so on.

● Support multi-channel different communication protocol acquisition and forwarding.

● Support serial port and Ethernet protocol clock synchronization, and SNTP timing services.

● Support historical data and log storage.

● With graphical client management tool, remote cloud management system.

● Large capacity real-time database system based on large capacity (more than 200,000 points) real-time database.

● Protocol multi-process independence. Each protocol process operates independently and does not influence each other.

● Redundant system architecture. The underlying system supports the two-hosts and two-network redundant system architecture, which can choose modes, such as single-host and single-network, single-host and double-network, double-host and double-network according to the needs.

● A set of cross-platform codes that supports running on different operating systems, such as Linux and Windows.

● Include rack-mounted, guide rail, wall-mounted, centralized and distributed types. 

● Data acquisition and forwarding in wind power, photovoltaic, hydropower, thermal power and steam power stations, data transmission in operation and maintenance channels, telecontrol communication for power dispatching.

● Internal and dispatch communications in transformer substation and substation.

● Data acquisition, calculation and forwarding of intelligent power station.

● Data communication, etc. between on-site intelligent equipment and all kinds of instrument sensors of industries, such as petroleum, chemical, water affairs and heat supply. 

● Flexible hardware configuration according to the actual operation on site. 

● Direct configuration based on direct application of running configuration file as the input of configuration tool. The configuration maintenance can be carried out as long as it can run on site.

● The device definition between different projects and different intervals of the same project can be copied, imported and exported.

● The defined device can be directly exported as a template.

● Device template and definition files are standard Excel files, which can be viewed and modify easily.

● Configurations based on text files transfers backups.

● Cloud debugging used as quick solution to on-site problems.
