Disconnected analysis software, the monitoring, diagnosing analysis software can realize that browsing data, tail rope rotating curve are drawn, tail rope rotary simulation moves
The functions such as picture, the inquiry of historical data, fault diagnosis and alarm, it is specific as follows：
(1) tail rope rotating curve is drawn
It can be drawn a diagram according to processing result.Chart abscissa is system time, and ordinate indicates rotating cycle, is defaulted suitable
It is positive direction when hour hands rotate, rotates counterclockwise as negative direction.On time shaft with erect long red line mark off promoted the time started, knot
The beam time.Judgment basis is that tail rope stops rotating when mine hoisting system is static, and sensor output signal is constant for a long time at this time；
Tail rope starts to rotate after mine hoisting system brings into operation, and Hall sensor exports pulse model.There is variation in signal to correspond to
Time reduce a signal period, default bring into operation from mine hoisting system at this time.Tail rope is static after promotion, at this time
Finally change corresponding one signal intensity cycle time of increase time from signal, it is believed that this can carve to promote the end time, use
Vertical red long wire tag.
(2) tail rope rotary simulation animation
Simulation animation figure of the monitoring interface center for circle tail rope hanger, band animation analog mine hoisting system operation
Justify the rotational case of tail rope hanger in the process.
(3) tail rope stops rotating alarm
When the signal of sensor output stops variation and do not arrive to promote the end time, it is believed that tail rope stops rotating or revolves at this time
Gyration is too small, issues primary alarm at this time, and the indicator light that stops rotating reddens.It is still to be tied to promotion within the defined time later
Beam time and signal does not change, it is believed that tail rope rotating device breaks down, and issues second-level alarm at this time, instruction of stopping rotating
Lamp starts to flash and continuously sends out alarm.
(4) tail rope spin data abnormal alarm
Tail rope stops rotating failure for soft fault.The tail rope rotating curve that mine hoisting system each run is obtained into
Row compares, and promotes the curve monitored for the first time and is considered initial curve, when the rotating curve that monitors and initial curve have compared with
When big difference, it is believed that tail rope rotating device health degree reduces.When difference between the two is greater than 30%, tail rope rotation is different
Normal indicator light reddens and issues alarm.
(5) alarm logging is inquired
When each above-mentioned alarm occurs, warning message is charged to alarm database automatically by monitoring of software, clicks monitoring of software
Right " alarm logging " button can check the database.
The industrial computer is also used to：The electricity of high energy battery is detected, but the electricity of the high energy battery is lower than
Battery capacity indication lamp becomes red when 5%, and continuously sends out alarm.
