When work data of the equipment 3 under n operating mode of large-scale maintenance machinery electrical system 1 is stationary singnal,
And the work data is when being normal function signal 0 or 1 in normal state, if obtaining the large-scale maintenance machinery under this working condition
When the jump of signal occur in the actual job data of the equipment 3 of electrical system 1, then judge the actual job data for failure letter
Number.Such as: in the failure real-time monitoring diagnosis of the equipment 3 of large-scale maintenance machinery electrical system 1, common several fault diagnosis feelings
Condition has:
(1) when equipment 3 carries out a certain operation, work data in normal state is normal function signal 0 or 1, if
Failure real-time monitoring diagnostic device 2 has monitored similarOrSignal jump, then diagnose this moment
Equipment 3 is malfunction.
(2) work data when the equipment 3 of large-scale maintenance machinery electrical system 1 under n operating mode is that dynamic is believed
Number, and when the work data is the pulse signal of rule variation in normal state, if obtained large-scale under this working condition
When irregular pulse signal occur in the actual job data of the equipment 3 of road maintainance machinery electrical system 1, then the actual job is judged
Data are fault-signal.When equipment 3 carries out a certain operation, in a period of time, the work in normal state monitored
Industry data are rule variationSignal, if failure real-time monitoring diagnostic device 2 monitors that this signal becomesThen diagnostic device 3 is malfunction this moment.It is subnormal that following table 2 show 08-32 tamping car tamping head underthrust one
When operation, the changing rule of depth location signal is made firm by ramming.Wherein, X13 fault-signal 10 indicate left tamping head after upper decline,
It is not returned to upper when lifting, X18 fault-signal 0 indicates that right tamping head after upper decline, does not reach bottom.

(3) when equipment 3 carries out a certain operation, the analog data under normal condition has a range determined, utilizes event
Hinder the value range that normal condition is arranged in real-time monitoring diagnostic device 2, carries out fault diagnosis.When large-scale maintenance machinery electrical system 1
Work data of the equipment 3 under n operating mode be Dynamic Signal, and the work data is one to determine in normal state
When the analog data of range, if obtaining the practical work of the equipment 3 of large-scale maintenance machinery electrical system 1 under this working condition
Industry data are more than the analog data range of setting, then judge the actual job data for fault-signal.
When the equipment 3 of large-scale maintenance machinery electrical system 1 breaks down in operation process, then failure real-time monitoring is examined
Disconnected 2 automatic spring fault message of device, carries out audible alarm prompt.Even if operator is handled not in time, can also be automatically stored
Fault message provides foundation for the subsequent lookup failure of operator.
The work of the equipment 3 of large-scale maintenance machinery electrical system 1 can be generally divided into three phases, it may be assumed that starting stage, fortune
Row order section and shutdown phase.It is control with computer:
(1) starting stage, from booting to the os starting stage, this period is mainly cmos (Complementary
Metal Oxide Semiconductor, the abbreviation of complementary metal oxide semiconductor) management computer, for large-scale road maintaining
For machinery, it is the preparation stage or puts the vehicle stage.Enter preparation from the equipment 3 of large-scale maintenance machinery electrical system 1
The stage is completed in the normal operation of stage to first time, is defined as starting stage, and the failure of this period is mostly that operator operates not
Correctly, this stage uses failure real-time monitoring diagnostic method of the present invention, especially handles specific signal, failure real-time monitoring
Diagnostic device 2 does not record and judges fault message actively, but is searched by operator by human-computer interaction, judges failure.
(2) operation phase, application software are started to work, and enter operation rank from the equipment 3 of large-scale maintenance machinery electrical system 1
Fault message is actively searched and recorded to Duan Hou, failure real-time monitoring diagnostic device 2, the mistake herein of failure real-time monitoring diagnostic device 2
Main function in journey is the operating mode of judgement and identification equipment 3, and some equipment 3 may only have a kind of operating mode, have
Equipment 3 may be there are many kinds of operating mode.It is selected from Work List by operator or by specific switch button group
Close judge and identify large-scale maintenance machinery electrical system 1 equipment 3 operating mode.
(3) shutdown phase, the process shut down computer shut down rank when the equipment 3 of large-scale maintenance machinery electrical system 1 is in
Section, large-scale maintenance machinery is in when returning the vehicle to the garage and knock off the stage, the failure of this period be mostly operated by operator it is incorrect caused by, therefore
Barrier real-time monitoring diagnostic device 2 does not actively record and judges fault message, at this time by by large-scale maintenance machinery electrical system 1
The signal of equipment 3 is compared with the correct signal for the state of returning the vehicle to the garage and knock off, and finds out fault-signal.
In large-scale maintenance machinery electrical system 1, the characteristics of motion of equipment 3 is periodic regularly changing or equipment 3
Motion state be basically unchanged, can well using the specific embodiment of the invention describe large-scale maintenance machinery electrically be
Failure real-time monitoring diagnostic method unite to carry out malfunction monitoring.As shown in table 3 below, record is under currently employed operating mode N
Whole fault messages of equipment 3.Wherein, X is input signal, and Q is output signal, and F is sensor signal, wherein the normal work of X1
Industry signal be 0, actual acquisition record signal be 010, collect one become 1 mutation, so by failure real-time monitoring
Diagnostic device 2 detects.The normal operation signal of Q1 is 010, indicates to become 1 from 0, then become 0, and the signal of actual acquisition record is
01, from 0 become 1 after remain unchanged, so being detected by failure real-time monitoring diagnostic device 2.The normal range (NR) of F0 is 2~5V, and
The signal of actual acquisition record is 1.5V, normal range is had exceeded, so being detected by failure real-time monitoring diagnostic device 2.
Partial fault information list of the 3 large-scale maintenance machinery electrical system equipment of table at operating mode N
