Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an elevator component parameter calibration method according to an embodiment of the present invention, where the embodiment is applicable to a case of automatically calibrating a parameter value of an elevator component, and the method can be performed by an elevator component parameter calibration device, which can be implemented in software and/or hardware, and can be configured in equipment, such as a computer, typically. As shown in fig. 1, the method specifically includes the following steps:
step S110, periodically obtaining parameter values of each elevator element in operation;
in a particular embodiment of the invention the elevator component parameter values are indicative of the service life of the elevator components, and the elevator component types comprise elevator buttons, door drives, wire ropes, indicator lights (lights and emergency lights), frequency converters, brakes, speed limiters, buffers, transformers, rectifiers, contactors, electromagnetic relays, safety tongs, etc. Accordingly, the evaluation criteria for specific service life needs to be selected according to the type of the component, and is not particularly limited herein. For example, when the elevator component is an elevator button, the evaluation criterion indicating the service life of the elevator component is the number of times the elevator button is triggered, i.e., the parameter value of the elevator button referred to herein is the number of times the elevator button is triggered.
It should be noted that the parameter values of the elevator components are acquired periodically during the actual operation of the elevator. The periodicity may be every 3 minutes or every 2 minutes, preferably a statistical analysis is performed on the data of the actual operation of the elevator to determine a time interval matching the actual situation. The manner in which the values of the parameters of the elevator components in operation can be periodically obtained is based on the fact that: in practical situations, the service life of the component, that is, the parameter value of the component, is a relatively large value, for example, for the parameter value of the elevator button, that is, the number of triggering times, the order of magnitude is ten thousand or more, so that, compared with a mode of acquiring the parameter value of the elevator component in real time, even if the limited number of triggering times is omitted in the middle, the influence on the accuracy of the result of the finally obtained calibration value of the elevator component parameter is very limited and can be ignored. More importantly, on the basis of ensuring the accuracy and the real-time performance of the acquired elevator element parameter values, the data processing amount and the occupied storage space are reduced to a certain extent.
Step S120, when the first elevator element in each elevator is not in fault, updating the parameter value of the first elevator element type in the stored elevator element parameter table according to the acquired parameter value of each elevator element;
in a particular embodiment of the invention, the first elevator element can represent the elevator element to be calibrated, i.e. the elevator element for which maintenance is currently required. The failure refers to the failure of the elevator components, for example, the failure of the elevator buttons can not realize the functions of floor selection, user going upstairs or downstairs, alarm prompt and the like by pressing the buttons. Each elevator component has a corresponding identifier for distinguishing the individual elevator components and for identifying whether they belong to the same elevator component type. For example, the identifier of the preset elevator component type is composed of 4 digits, and the identifier of the elevator component is composed of 4 digits followed by a number, wherein the first 4 digits are used for indicating the type of the elevator component, so that whether the two elevator components belong to the same elevator component type can be judged by identifying whether the first 4 digits in the identifiers of the two elevator components are the same. If the identifier of the elevator button is 0100, the identifier of each elevator button can be 0100-1, 0100-2 or 0100-3, the former 4 bits of the identifier of each elevator element are 0100, and the identifier of each elevator button is 0100, so that each elevator button can be classified into the elevator element type of the elevator button. It is understood that the setting rule of the specific elevator component and the identifier of the type of the elevator component is set according to the actual situation, and is not limited specifically here.
The elevator element parameter table stores parameter values of elevator element types, and in addition, contents such as update time, elevator job numbers, calibration times and the like of the parameter values of the elevator element types are stored. And when the first element in each elevator does not have a fault, updating the parameter value of the first elevator element type stored in the elevator element parameter table according to the acquired parameter value of each elevator element at the moment. Optionally, if the first elevator component is each elevator button, when the elevator button is detected to be triggered, the parameter value of the corresponding elevator button is updated, where the updating may be accumulation of the triggering times based on the current parameter value, and the accumulation operation of the parameter value is performed every time the elevator button is triggered, where usually, the accumulated value is consistent with the triggering times, that is, the parameter value of the elevator button is correspondingly increased by 1 when the elevator button is triggered once. By updating the parameter value of the first elevator element type in the elevator element parameter table, the parameter value of the first elevator element type stored in the elevator element parameter table is up-to-date, and data support is provided for subsequently acquiring the parameter calibration value of the first elevator element type.
It should be noted that, because the elevator component parameter table further stores the update time of the parameter value of the elevator component type, optionally, while updating the parameter value of the first elevator component type, the corresponding update time is also recorded and the record is stored in the elevator component parameter table, which can be used as one of the bases for subsequently updating the parameter value of the first elevator component type.
And S130, taking the parameter value of the first elevator component type in the elevator component parameter table as the parameter calibration value of the first elevator component type.
In a particular embodiment of the invention, since the parameter values of the first elevator component type stored in the elevator component parameter table are updated in real time on the basis of the periodically acquired parameter values of the first elevator component in operation, the parameter value of the first elevator element type in the elevator element parameter table can thus represent the latest parameter value of the first elevator element type that can be retrieved at the present moment, on the basis of which it is taken as the parameter calibration value of the first elevator element type, which can subsequently be taken as the parameter setting value of the first elevator element type, when the acquired parameter value of the first elevator element in operation reaches the parameter setting value or the difference between the parameter setting value and the parameter value is less than the preset threshold value, an alarm prompt is sent to remind a user of maintenance or replacement, and the normal operation of an elevator element is ensured, so that the elevator can run normally.
It should be noted that, when the parameter value of the first elevator component type in the stored elevator component parameter table is updated, the original stored parameter value may be retained or may be covered, where the retention means that a parameter value storage item is newly added, and the covering means that the original stored parameter value is replaced by the updated parameter value, and the original stored parameter value is deleted. The specific implementation manner is set according to actual conditions, and is not particularly limited herein. Preferably, the original storage parameter value is reserved, and is deleted after the set time limit is exceeded, so that the historical data can be inquired in the set time limit, and meanwhile, the problem that the memory is occupied due to the fact that the historical data stored after the set time limit is exceeded loses effectiveness is solved.
According to the technical scheme, the parameter values of the elevator elements in operation are obtained periodically, when the first elevator element in each elevator is not in fault, the parameter value of the first elevator element type in the stored elevator element parameter table is updated according to the obtained parameter values of the elevator elements, and the parameter value of the first elevator element type in the elevator element parameter table is used as the parameter calibration value of the first elevator element type, so that the problems that the parameter value calibration of the elevator element in the prior art needs manual participation for adjustment and the test data is limited are solved, the parameter values of the elevator elements are calibrated automatically, and the working efficiency is improved while the accuracy of the parameter calibration value of the elevator element is improved.
Further, on the basis of the above technical solution, before updating the parameter value of the first elevator component type in the stored elevator component parameter table according to the obtained parameter value of each elevator component when the first elevator component in each elevator is not in fault, the method further includes:
and when the first elevator component in each elevator does not have a fault and the parameter value of the first elevator component type does not exist in the stored elevator component parameter table, adding the acquired parameter value of the first elevator component as the parameter value of the first elevator component in the elevator component parameter table.
In a specific embodiment of the invention, when the first elevator element in each elevator has no fault and the stored elevator element parameter table does not have the parameter value of the first elevator element type, that is, when the two conditions are met, a storage item of the parameter value of the elevator element is added in the elevator element parameter table, that is, the obtained parameter value of the first elevator element is used as the parameter value of the first elevator element in the elevator element parameter table.
Through the operation of the step, the parameter values of each elevator element type are stored in the elevator parameter table, so that data support is provided for acquiring the parameter calibration value of the first elevator element type subsequently.
Further, on the basis of the above technical solution, before the parameter value of the first elevator component type in the elevator component parameter table is used as the parameter calibration value of the first elevator component type, the method further comprises:
and judging whether the parameter value of the first elevator element type in the elevator element parameter table meets a preset condition.
Further, on the basis of the above technical solution, taking the parameter value of the first elevator component type in the elevator component parameter table as the parameter calibration value of the first elevator component type may specifically include:
and if the parameter value of the first elevator component type in the elevator component parameter table meets the preset condition, taking the parameter value of the first elevator component type in the elevator component parameter table as the parameter calibration value of the first elevator component type.
In a specific embodiment of the present invention, the preset condition refers to a condition that an absolute value of a difference between a parameter value of the first elevator element type after update and a parameter value of the first elevator element type before update stored in the current elevator element parameter table needs to be satisfied, and only when the absolute value of the difference satisfies the condition, the parameter value of the first elevator element type in the elevator element parameter table is used as a parameter calibration value of the first elevator element type.
It should be noted that the condition that the absolute value of the difference needs to satisfy may be specifically that when the absolute value of the difference is greater than or equal to a preset threshold, the absolute value of the difference may also be in a preset value range, where the preset threshold and the preset value range may be set according to an actual situation, and are not limited specifically here. Illustratively, if the first elevator component type is an elevator button, and correspondingly, the parameter value is the number of times of triggering, the preset threshold value can be set to be 1000 times, and the preset value range is 500 times and 3000 times, preferably, the condition that the absolute value of the difference value needs to be satisfied is that the absolute value of the difference value is in the preset value range, because when the absolute value of the difference value is too small, such as 3 times, there is no need to update the parameter calibration value of the elevator button; when the absolute value of the difference is too large, the problem that the obtained parameter value of the elevator button is inaccurate due to system errors can occur, in this case, the parameter calibration value of the elevator button does not need to be updated temporarily, and after the reason is found out subsequently, the parameter value obtaining and parameter value updating operations are carried out again.
By judging whether the parameter value of the first elevator element type in the elevator element parameter table meets the preset condition or not, and only after the preset condition is met, the parameter value of the first elevator element type in the elevator element parameter table is used as the parameter calibration value of the first elevator element type, namely, the updating operation of the parameter calibration value of the first elevator element type is carried out, so that the parameter calibration value of the first elevator element type is ensured to have effectiveness, and the data processing amount is reduced to a certain extent.
Further, on the basis of the above technical solution, periodically acquiring parameter values of each elevator component in operation may specifically include:
the elevator components of the elevators in operation are monitored.
In a particular embodiment of the invention the monitoring of the elevator components of the running elevators is aimed at obtaining the values of the parameters of the running elevator components, i.e. the values of the parameters of the elevator components are correspondingly obtained during the monitoring.
Further, on the basis of the above technical solution, when the first elevator element in each elevator is not in fault, updating the parameter value of the first elevator element type in the stored elevator element parameter table according to the obtained parameter value of each elevator element, specifically, the method may include:
when a first elevator element in each elevator is triggered, judging whether the first elevator element fails;
if the first elevator component is not faulty, the parameter value of the first elevator component in the stored elevator component parameter table is incremented by 1.
In a particular embodiment of the invention, the operation of determining whether the first elevator element is defective is initiated when the first elevator element in the elevators is triggered, wherein triggering refers to the elevator element being in use, for example, when the first elevator element is an elevator button, triggering refers to the operation of the elevator button being pressed. When the situation that the elevator button is not in fault is monitored, the triggering times of the elevator button stored in the elevator element parameter table are added with 1, namely the parameter value is added with 1.
Through the operation of the step, the parameter value of the first elevator element type stored in the elevator parameter table is updated in real time, so that data support is provided for acquiring the parameter calibration value of the first elevator element type subsequently.
Further, on the basis of the above technical solution, when the first elevator component in each elevator is triggered, after judging whether the first elevator component is in failure, the method further includes:
and if the first elevator component has a fault, taking the parameter value of the first elevator component type in the elevator component parameter table as the parameter calibration value of the first elevator component type.
In a specific embodiment of the invention, when the first elevator element fails, the parameter value of the first elevator element type stored in the elevator parameter table is not increased any more, and the parameter value obtained at this time is used as the parameter calibration value of the first elevator element type. Illustratively, when the first elevator component is an elevator button, the parameter value of the elevator button stored in the elevator component parameter table is used as the parameter calibration value of the elevator button when the first elevator component is detected to be in failure.
Further, on the basis of the above technical solution, updating the stored parameter value of the first elevator component type in the elevator component parameter table according to the obtained parameter value of each elevator component may specifically include:
updating the parameter value of each first elevator element in a stored elevator element parameter table according to the acquired parameter value of each elevator element;
in a special embodiment of the invention the elevator component parameter table has stored therein the parameter value of each first elevator component, i.e. for a first elevator component there is stored an entry for a parameter value. And updating the parameter value of each corresponding first elevator element stored in the elevator element parameter table according to the acquired parameter value of each elevator element. Illustratively, if the number of the acquired first elevator components is 3, the first elevator components are respectively a first elevator component a, a first elevator component B and a first elevator component C, correspondingly, the elevator component parameter table has a storage item a of the parameter value of the first elevator component a, a storage item B of the parameter value of the first elevator component B and a storage item C of the parameter value of the first elevator component C, when the first elevator component a is triggered, the storage item a in the elevator component parameter table is correspondingly updated, and when the first elevator component B is triggered or when the first elevator component C is triggered, the storage item B and the storage item C in the elevator component parameter table are respectively updated based on the same mode.
And when the number of the acquired first elevator components reaches a preset component number threshold value, calculating an average value of the acquired parameter values of at least one first elevator component, and calculating the parameter values of the type of the first elevator component according to the average value and a preset proportionality coefficient.
In a specific embodiment of the present invention, the preset number threshold is used as a basis for achieving the batch, that is, when the number of the obtained first elevator components reaches the preset number threshold, that is, when the batch achievement condition is satisfied, an average value of the number of the obtained first elevator components is calculated according to the parameter values of the plurality of first elevator components obtained at present, and the parameter value of the type of the first elevator component is calculated according to the average value and a preset proportionality coefficient.
Illustratively, if the threshold value of the number of the first elevator components is preset to be K, and the preset proportionality coefficient is η, xiThe parameter value representing the first elevator component obtained,
denotes the average of the calculated parameter values of the first elevator element, X denotes the parameter value of the first elevator element type, i ═ 1,2, 3.., K ∈ η ∈ (0, 1)]. When the number of the obtained first elevator elements reaches the number threshold value, namely when a batch achievement condition is met, obtaining parameter values x of a plurality of first elevator elements according to the obtained parameter values xiCalculating to obtain the average value
In particular, the method comprises the following steps of,
according to the mean value
And the predetermined scaling factor η, a parameter value X for the first elevator component type is calculated, specifically,
the values of the number threshold and the scaling factor need to be set according to actual conditions, and are not specifically limited herein, for example, K is 10000, and η is 0.9.
Since the calculated parameter values of the first elevator element type are based on a large number of parameter values of the first elevator element, the parameter values of the first elevator element type obtained in the above-described manner are brought closer to the state of use of the actual elevator element, and it is therefore more reasonable to subsequently use the parameter values of the first elevator element type as parameter calibration values for the first elevator element type.
