When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
fig. 1 is a flow chart illustrating a fault early warning method according to an exemplary embodiment, as shown in fig. 1, the method including:
Step S11, obtaining the operation parameters of the monitored equipment;
step S12, calculating a risk value of the monitored equipment according to the operation parameters;
and step S13, judging whether the monitored equipment has aging risk and/or failure risk according to the risk value, and if so, sending risk early warning.
it should be noted that, the applicable scenarios of the technical solution provided by this embodiment include, but are not limited to: the system comprises a building internal equipment monitoring system, a factory internal equipment monitoring system, a campus internal equipment monitoring system, a smart city equipment monitoring system, a safety city equipment monitoring system and the like.
Taking the technical solution provided by this embodiment as an example, the operating parameters of the monitored equipment include, but are not limited to: the rotating speed, the service life, the failure times and the like of a fan in a building; the frequency, the wind speed, the working mode, the service life, the repair times and the like of a compressor of an air conditioner in a building; the working time, the switching times, the current and voltage values and the like of the lamps in the building.
it can be understood that, according to the technical scheme provided by this embodiment, by obtaining the operation parameters of the monitored equipment, according to the operation parameters, the risk value of the monitored equipment is calculated, and according to the risk value, whether the monitored equipment has an aging risk and/or a failure risk is judged, if so, a risk early warning is sent out, so that the advanced early warning of the aging risk and/or the failure risk of the monitored equipment in the building is realized, the troubleshooting and updating of the aging equipment are facilitated, the failure location and maintenance of the non-aging equipment are facilitated, the maintenance speed of the monitored equipment is improved, the potential safety hazard in the building is reduced, the user experience is good, and the satisfaction degree is high.
it should be noted that, in the step S12, the risk value of the monitored equipment is calculated according to the operating parameter, which includes multiple implementation methods, where one implementation method is:
drawing an operation parameter change curve of the monitored equipment according to the operation parameters;
Calculating a fault boundary value of the monitored equipment according to the use instruction and the basic parameter table of the monitored equipment; and if the difference value between the fault boundary value and the operation parameter change curve is greater than a preset risk value, sending a risk early warning.
in addition, the step S12 of calculating the risk value of the monitored equipment according to the operating parameter may be implemented by:
drawing a use portrait of the monitored equipment according to the operation parameters, and storing the use portrait in a database;
Drawing the usage record of the monitored equipment into a curve graph, and displaying the curve graph on a management page;
Estimating the actual service life of the monitored equipment according to the standard service life of the equipment and the loss caused by the actual use behavior, and marking an estimated life warning line on an equipment curve;
And calculating the current actual use loss of the monitored equipment in real time, calculating a residual life value, and sending out risk early warning when the residual life value of the equipment reaches a warning value.
Preferably, the risk values include: capacity values, and/or failure rates;
The capacity value is a residual life value converted according to the current actual use loss of the monitored equipment.
it will be appreciated that quantifying the risk value with various computational indicators facilitates the system in assessing the risk of the monitored equipment. The failure rate may be calculated by dividing the number of accumulated failures of the monitored device in the current year (or the current month, the current week) by the total number of days in the current year (or the current month, the current week), or may be calculated by dividing the number of accumulated failures of the monitored device in the current year (or the current month, the current week) by the total number of on-times in the current year (or the current month, the current week).

if the monitored equipment is judged to have the aging risk, and if the monitored equipment does not have the aging risk, the monitored equipment is judged to have the fault risk, namely, the fault detection is only carried out in the effective service life of the monitored equipment, and if the effective service life of the monitored equipment is exceeded, the fault detection is not carried out any more, so that the invalid fault detection step is avoided, the concurrent process processing is reduced, the system response speed is high, and the user experience is high.

and if the capability value of the monitored equipment is less than or equal to the aging warning value, judging that the monitored equipment has the aging risk.

preferably, the aging warning value is estimated according to the capacity value of the equipment. For example, the capability value of the apparatus is 10 years, and 15% of the capability value, that is, 1.5 years, may be set as the aging guard value.
Taking the standard life of the device as 20 years and the aging warning value as 3 years as an example, the determining whether the monitored device has an aging risk includes:
if the converted remaining life value (namely the ability value) is 8 years according to the current actual use loss of the monitored equipment, judging that the monitored equipment does not have aging risk because the ability value is larger than an aging warning value;
if the converted remaining life value (i.e. the ability value) is 2 years according to the current actual use loss of the monitored equipment, the monitored equipment is judged to have aging risk because the ability value is less than the aging warning value.
Preferably, the determining whether the monitored equipment has a failure risk includes:
and if the fault rate of the monitored equipment is greater than or equal to the preset risk value, judging that the monitored equipment has fault risk.
preferably, the preset risk value is set according to experimental data or historical empirical values.
for example, if the failure rate of the monitored equipment is 50% and the preset risk value is 10%, it is determined that the monitored equipment has a failure risk because the failure rate is greater than the preset risk value.
preferably, the method further comprises:
And if the monitored equipment is judged to have aging risks and/or failure risks, generating a maintenance task and informing corresponding equipment management personnel to process.
Preferably, the method further comprises:
the method comprises the steps that a risk processing scheme library of monitored equipment is established in advance, and various aging risks and/or risk processing schemes corresponding to fault risks are stored in the risk processing scheme library;
And if the risk processing scheme matched with the currently determined risk type is called from the risk processing scheme library, adding the called risk processing scheme into the maintenance task, so that the equipment management personnel can process the aging risk and/or the fault risk by referring to the risk processing scheme.
