Parameter carries out real-time measurement.Operation monitor (LOP) system is that operator carries out basic operation to gas engine group by machine
Control device, the operating parameters such as the revolving speed of gas engine, oil pressure, water temperature, A/B row temperature, single cylinder row temperature, admission pressure and
Corresponding alarm parameters are shown.
By the machine operation monitor (LOP) include main control module, display unit, security module, RS485 serial port module with
And cabinet；Main control module, security module, RS485 serial port module are installed in cabinet, and display unit is placed on cabinet.
Cabinet be equipped with power switch, starting, shutdown, emergency shutdown, pre- confession, main gas valve switch, reset, self-test, noise reduction/
Timing button and alarm lamp.The cabinet has good leakproofness, and structure is convenient for the replacement of device and the maintenance of route.
The security module is used to monitor the parameters of gas engine, transports gas engine under normal range (NR)
Type, monitoring measured value with setting more limits value be compared, when security system monitoring measured value and setting get over limits value into
Row compares, when the measured value of the revolving speed of gas engine, water temperature, gas engine row temperature, single cylinder row's temperature is more than more limits value,
Security module sends mould signal to active module, issues halt instruction or output sound-light alarm by main control module；Admission pressure
When measured value is lower than more limits value, main control module exports sound-light alarm；When the measured value of oil pressure is lower than more limits value, master control mould
Block issues halt instruction or output sound-light alarm.
