MMS6823 Rotating Machinery Vibration Data Acquisition Board
It is a supporting product of MMS6000 vibration monitoring and protection system of turbogenerator produced by German epro company. system has
Real-time data collection, processing, transmission and other functions. it is widely applicable
Large and medium-sized for electric power, petrochemical, coal mine and metallurgical industries
Rotating machinery, such as: turbogenerators, water turbines, electric
Machines, compressors, pumps and fans, etc.
The board includes data acquisition and data transmission functions. and
MMS6000 series boards carry out RS485 data communication,
Realize data acquisition and related settings; based on TCP/IP
Data transmission can realize remote control, remote monitoring, remote
Configuration, remote debugging function. The board system software adopts the
Windows CE.net 4.1 operating system of Microsoft Corporation of the United States.
data collection:
MMS6823 continuously visits the MMS6000 board connected to the bus through the RS485 bus to realize the data
According to the real-time collection function, at the same time, the received eigenvalue data and the report and board status data are converted into standard
MODBUS protocol and TCP/IP protocol output. Data acquisition, communication service program adopts multi-thread technology,
The data read and write operations of each MMS6000 board channel are all parallelized, and each serial port is controlled by a separate
Threads are used to complete the reading and writing work to ensure that the data between channels is synchronized.
The second to ninth serial ports are used to connect MMS series modules, and each serial port will be connected with at most
12 MMS modules, each with two channels, can connect up to 8x12x2=192
data channel;
Data transmission: Data output is divided into Modbus and TCP/IP:
Modbus protocol: the first serial port RS232 is the Modbus communication port. MODBUS output can
Choose MODBUS RTU or MODBUS ASCII protocol mode, the protocol mode can be set by XML configuration file
Modbus field to set. Receive characteristic value data and report and board status data from MMS6000
It can be accessed by DCS, DEH and other systems connected with MMS6823.
