Embodiment 1
Present embodiment discloses a kind of diagnosis control methods based on Hydraulic Power Unit technical water supply water pressure data process, so that When data exception occurs in data collection terminal, analysis is carried out to overall data, just corresponding Hydraulic Power Unit technical water supply hydraulic pressure is carried out Corresponding start stop operation avoids having an impact entire automatic control system.
Specifically, the present embodiment is illustrated by taking Hydraulic Power Unit technical water supply as an example, as shown in Figure 1, being based on Hydraulic Power Unit The diagnosis control method of technical water supply water pressure data process, comprising the following steps:
S1: setting Hydraulic Power Unit technical water supply data and time procedure relation, the data include control data and With at least one non-control of control data correlation;The control data are hydraulic pressure, and the non-control includes hydraulic pressure Rise/fall speed, technical water supply flow, cooler water inlet/leaving water temperature, bearing oil temperature, cooler air inlet/leaving air temp, One or more of motor current and motor voltage.
Wherein, the control data are that the main monitoring of Hydraulic Power Unit technical water supply hydraulic pressure controls data and control foundation (i.e. hydraulic pressure itself), the non-control are other data (i.e. hydraulic pressure rise/fall speed associated with control data Degree, technical water supply flow, cooler water inlet/leaving water temperature, bearing oil temperature, cooler air inlet/leaving air temp, motor current and One or more of motor voltage).
Also, as control data hydraulic pressure, can be aerial cooler and/or oil cooler intake pressure and/or Discharge pressure.
Preferably, in the present embodiment, the non-control includes process data detected value itself and/or mistake number of passes According to the pace of change of detected value.
Wherein, in the present embodiment, control object is Hydraulic Power Unit technical water supply hydraulic pressure, and the control data are water Pressure.And its corresponding non-control include hydraulic pressure rise/fall speed, technical water supply flow, cooler intake/go out water temperature One or more of degree, bearing oil temperature, cooler air inlet/leaving air temp, motor current and motor voltage.
That is, in general, to the control of Hydraulic Power Unit technical water supply hydraulic pressure according to based on hydraulic pressure, therefore The data can be control data.And the hydraulic pressure rise/fall speed due to Hydraulic Power Unit technical water supply, technical water supply flow, Cooler water inlet/leaving water temperature, bearing oil temperature, cooler air inlet/leaving air temp, motor current and motor voltage and hydraulic pressure Correlation, therefore be in the present embodiment non-control.
The limit process section of each data is arranged in S2.
Wherein, step S2 is used for Initialize installation, and the step specifically includes following three kinds of situations:
(1) it by the artificially limiting condition of setting Hydraulic Power Unit technical water supply hydraulic pressure under normal operation, obtains in the limit The limit process section of the Hydraulic Power Unit technical water supply water pressure data and its non-control under operating condition, i.e., the described water engineer The maximum value and minimum value of data when limiting condition occurs in normal operation in group technical water supply hydraulic pressure;Or:
(2) water pressure data and its non-controlling number detected after being put into operation according to the Hydraulic Power Unit technical water supply hydraulic pressure According to automatically limit process section being arranged, that is, obtain the Hydraulic Power Unit technical water supply hydraulic pressure each data in the process of running Maximum value and minimum value;Or:
(3) by way of software emulation, when there is limiting condition in operation in simulation Hydraulic Power Unit technical water supply hydraulic pressure The maximum value and minimum value of the data of acquisition, the setting in Lai Jinhang data limit process section.
Specifically, in the present embodiment, by any method in above-mentioned three kinds of modes, Hydraulic Power Unit skill can be obtained The maximum value and minimum value of the practical highest hydraulic pressure of art water supply pressure and minimum hydraulic pressure and hydraulic pressure rise/fall speed, technology supply The maximum value and minimum value of water flow, cooler water inlet/leaving water temperature maximum value and minimum value, the maximum value of bearing oil temperature and Minimum value, cooler air inlet/leaving air temp maximum value and minimum value, the maximum value of motor current and minimum value, motor The maximum value and minimum value of voltage.
It is configured the data of above-mentioned acquisition as the limit process section of each process data.And the limiting value being arranged It can be actual numerical value or the certain percentage of actual numerical value.
S3, the hydraulic pressure of real-time detection Hydraulic Power Unit technical water supply, when hydraulic pressure goes beyond the limit of process section, to hydraulic pressure diagnosis report It is wrong;And/or: the non-control of real-time detection Hydraulic Power Unit technical water supply is right when non-control goes beyond the limit of process section Non-control diagnosis reports an error.
Wherein, section gone beyond the limit of for the control data and non-control goes beyond the limit of section, including with Lower three kinds of situations:
(1) when the input channel failure for detecting data, i.e., data can not be detected or can not be acquired (at this time by It is considered to go beyond the limit of section).
It corresponds in this present embodiment, specially event occurs for the hydraulic analogue amount input channel of Hydraulic Power Unit technical water supply hydraulic pressure Barrier, water pressure data can not obtain.
(2) when the data-signal detected is not in the detection range of the input channel, i.e., data are beyond normal detection model It encloses.
And correspond in this present embodiment, specifically by the hydraulic analogue amount input channel of Hydraulic Power Unit technical water supply hydraulic pressure The signal of input, within the scope of the data being able to detect that beyond the analog input channel.
(3) within the limit process section that the data-signal detected is not arranged in step s 2.
It is corresponding in this present embodiment, specially hydraulic pressure, hydraulic pressure rise/fall speed, technical water supply flow, cooler into Whether water/leaving water temperature, bearing oil temperature, cooler air inlet/leaving air temp, motor current and motor voltage are in step S2 In limit process section within.
In this step, it when there is any one situation of three cases above, that is, is possible to occur for data itself Abnormal (for example control the Data Detection sensor degradation of data, the data detection device damage of non-control or both and pass Defeated path loss etc.), rather than there is exception in environment.
Therefore, it when control data go beyond the limit of process section or non-control goes beyond the limit of process section, uses The form to report an error, rather than directly control Hydraulic Power Unit technical water supply hydraulic pressure is removed as foundation.
Based on above three step, in one of preferred embodiment of the present embodiment, using the realization of faults-tolerant control The case where mode, which mainly solves control data error reporting, specifically:
When the hydraulic pressure of real-time detection goes beyond the limit of process section, and non-control is within limit process section When, be to carry out faults-tolerant control according to the hydraulic pressure of Hydraulic Power Unit technical water supply with non-control, i.e., with non-control be according to It is indirectly controlled according to the hydraulic pressure to Hydraulic Power Unit technical water supply, it is ensured that Hydraulic Power Unit technical water supply hydraulic pressure is not to control datagram Mistake cause its control failure and it is out of service.
I.e. in the example of the present embodiment, when Hydraulic Power Unit technical water supply hydraulic pressure goes beyond the limit of section, not with the hydraulic pressure Data control Hydraulic Power Unit technical water supply hydraulic pressure, but with hydraulic pressure rise/fall speed, technical water supply flow, cooling Device water inlet/leaving water temperature, bearing oil temperature, wherein one in cooler air inlet/leaving air temp, motor current and motor voltage A or a variety of non-control control Hydraulic Power Unit technical water supply hydraulic pressure.Be specifically chosen it is several or which, root It is configured according to actual conditions.
For example, passing through (autonomous learning and autonomous modified, preference) Hydraulic Power Unit technical water supply hydraulic pressure operation Hydraulic pressure rise/fall speed, technical water supply flow, cooler water inlet/leaving water temperature, bearing oil temperature, cooler are entered the wind/go out wind-warm syndrome Degree, motor current and motor voltage.
When hydraulic pressure be higher than limit section in maximum or minimum value when, according to above-mentioned calculating obtain hydraulic pressure rise/under Reduction of speed degree, technical water supply flow, cooler water inlet/leaving water temperature, bearing oil temperature, cooler air inlet/leaving air temp, electronic electromechanics Stream and motor voltage continue to control Hydraulic Power Unit technical water supply hydraulic pressure automatic work, or judge Hydraulic Power Unit technical water supply Whether hydraulic pressure work is normal.Simultaneously correspondingly, the corresponding alarm signal of control data is generated.
Using such mode, the sensor signal for detecting hydraulic pressure as control data source can be diagnosed It reports an error.
In addition, in general, Hydraulic Power Unit technical water supply hydraulic pressure rise/fall speed, technology in above content Water supply flow, cooler water inlet/leaving water temperature, bearing oil temperature, cooler air inlet/leaving air temp, motor current and motor (i.e. the acquisition of non-control is in the data collected that voltage is in limit process section for hydraulic pressure based on control data Subject in limit process section).Specifically:
Detection technique water supply flow, if art water supply flow is more than the process interval range allowed, (i.e. non-control does not exist When in the limit section being arranged in step S3), then send the report that Hydraulic Power Unit technical water supply flow is more than the constant interval allowed Alert signal, it is otherwise automatic (when i.e. in the limit section that is arranged in step s3 of non-control) to calculate technology in whole process and supply Water flow continuous autonomous learning and is independently corrected in control process.
The hydraulic pressure rise/fall speed of Hydraulic Power Unit technical water supply, cooler water inlet/leaving water temperature, bearing oil temperature, cooling Device air inlet/leaving air temp, motor current are also similar with motor voltage, herein without repeating.
Based on above three step, in another preferred embodiment of the present embodiment, using the realization of PREDICTIVE CONTROL Mode, the PREDICTIVE CONTROL mainly solve the case where non-control reports an error, specifically:
When the non-control of the Hydraulic Power Unit technical water supply of real-time detection goes beyond the limit of process section, with hydraulic pressure be according to According to the PREDICTIVE CONTROL for carrying out hydraulic pressure to Hydraulic Power Unit technical water supply, i.e., in the case where non-control diagnosis reports an error, according to water Press data in advance and/or hysteresis manner, to Hydraulic Power Unit technical water supply hydraulic pressure carry out PREDICTIVE CONTROL.
Since when control data are in limit process section, non-control is not as Hydraulic Power Unit technical water supply hydraulic pressure Control foundation, but when it goes beyond the limit of process section can also illustrate related content to go wrong, (collection terminal itself is asked Topic or data acquisition go wrong), therefore the situation that can be reported an error at this time according to non-control, in advance and/or hysteresis manner, Hydraulic Power Unit technical water supply hydraulic pressure is controlled.
Specifically, in the example of the present embodiment, when hydraulic pressure is in limit process section, and Hydraulic Power Unit technical water supply Hydraulic pressure rise/fall speed, technical water supply flow, cooler water inlet/leaving water temperature, bearing oil temperature, cooler are entered the wind/go out wind-warm syndrome When one or more of degree, motor current and motor voltage are other than limit process section, with reference to hydraulic pressure to water Power machine set technology water supply pressure carries out the control in advance and/or lagged.
Wherein, PREDICTIVE CONTROL and faults-tolerant control are existing for the relationship of "and/or".
In addition, the realization based on above-mentioned any content, in the present embodiment, the limit process section replace with positive and negative Deviation range, wherein the acquisition modes of the positive and negative deviation range the following steps are included:
S21 ': in Hydraulic Power Unit technical water supply hydraulic pressure actual motion, the continual detection Hydraulic Power Unit technology The procedure relation of water supply pressure and associated non-control and time;
S22 ': the average value of data time process is obtained, and establishes standardized normal distribution law curve;
S23 ': the positive and negative deviation model of data procedures is determined according to the average value and standardized normal distribution law curve It encloses.
That is, the present embodiment also provides a kind of diagnostic method, judgement in data can be made from limit process area Between replace with positive and negative deviation range, when determine including control data and non-control including process data be more than positive negative bias Poor range when not meeting normal distribution law requirement, reports an error to Hydraulic Power Unit technical water supply hydraulic pressure, the appearance in preferred embodiment Mistake control and PREDICTIVE CONTROL.
Using such mode, so that the judgement section of data more meets objective law, the differentiation control of homogeneous object is realized System, solve the prior art be unable to automatic identification each the characteristic of specific Hydraulic Power Unit technical water supply hydraulic pressure, also can not be according to specific Properties of Objects carries out the problem of realizing differentiation control.
Wherein, be arranged positive and negative deviation range mode it is identical as the mode in above-mentioned setting limit process section, herein not into Row repeats.
In addition, in the present embodiment, change can be calculated according to the process data of the Hydraulic Power Unit technical water supply hydraulic pressure The average value of change and the positive and negative deviation range determined according to standardized normal distribution rule, and migration situation at any time, It determines that the process data of the Hydraulic Power Unit technical water supply hydraulic pressure changes with time trend, diagnoses the Hydraulic Power Unit technology and supply The operation conditions and trend analysis of water hydraulic pressure, for evaluating the healthy impaired condition of the Hydraulic Power Unit technical water supply hydraulic pressure.
Under normal conditions, limit process section just starts a period of time of starting for Hydraulic Power Unit technical water supply hydraulic pressure, It is less for calculating the data of positive and negative deviation range at this time.And positive and negative deviation range for replacing the limit after running for a period of time Process section, so that data judgement has Hydraulic Power Unit technical water supply hydraulic pressure self character.
And, it is preferable that positive and negative deviation range can change, and in the case where data are more, ratio is smaller.Example Such as, under the initial situation used, can using around average value 60% floating, and stage using around average value 95% very To the floating for being 99%.
