Abstract
The invention uses an embedded computer structure and comprises: an embedded management module, multi functional modules, a display and a touch screen controlling circuit. Each functional module is used for processing the signals from each sensor signal collecting circuit; the embedded management module is used for controlling and transmitting the data through a bus interface circuit connection functional module of high speed universal asynchronous receiver transmitter (UART); said embedded management module has an TCP/IP network interface, a RS232 or RS 485 communication circuit interface; said TCP/IP, RS 232 or RS 485 communication circuit interface are connected to the upper computer to receive the configuration of the upper computer and data collecting command; the output of the embedded management module is connected to the display and touch screen controlling circuit.
Description
technical field [0001] The invention relates to an embedded instrument and a setting method, in particular to a device and a setting method for the operating state of a rotating machine and intelligent monitoring and protection, and belongs to the field of monitoring and protecting the operating state of the machine. Background technique [0002] Many large rotating machinery, mainly including steam turbines, water turbines, generators, motors, compressors, turbines, centrifugal pumps, etc., are key equipment in petrochemical, electric power, metallurgy, coal, nuclear energy and other industries. During mechanical operation, due to factors such as strength, structure, vibration, control reliability, and materials and processes, equipment failures or even damage are often caused, resulting in serious losses. The monitoring and protection of rotating equipment has become a key measure for safe production and economic benefits of enterprises. Therefore, the research on conditi...
