The user interface 1003 may include a Display screen (Display), and the optional user interface 1003 may further include a standard wired interface and a wireless interface, and the wired interface for the user interface 1003 may be a USB interface in the present invention. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) or a Non-volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the contactor state evaluation device, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in FIG. 1, memory 1005, identified as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a contactor status evaluation program.
In the contactor state evaluation device shown in fig. 1, the network interface 1004 is mainly used for connecting a background server and performing data communication with the background server; the user interface 1003 is mainly used for connecting user equipment; the contactor state evaluation device calls a contactor state evaluation program stored in the memory 1005 through the processor 1001 and performs the contactor state evaluation method provided by the embodiment of the present invention.
Based on the hardware structure, the embodiment of the contactor state evaluation method is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the contactor state evaluation method of the present invention, and the first embodiment of the contactor state evaluation method of the present invention is provided.
In a first embodiment, the contactor state evaluation method includes the steps of:
step S10: and acquiring state parameter information of the elevator contactor root under a preset parameter dimension.
It should be understood that the execution body of the present embodiment may be an elevator control system. The elevator control system comprises a sampling board or a main board for information acquisition and a microprocessor unit. The elevator control system can be a system formed by connecting a sensor or a sampling board with a single chip microcomputer, an ARM (advanced RISC machine), even a computer, a server and other processing equipment, and referring to fig. 3, the sampling board or a main board, an elevator contactor and a power supply are connected in a specific manner.
It should be noted that the preset parameter dimension is up to the preset parameter dimension. The preset parameter dimension may include: and the state parameter information of the elevator contactor such as action voltage, contact abnormal frequency, contact resistance value, action response time and the like. The state parameter information of the elevator contactor refers to parameter information for reflecting the current state of the elevator contactor. The state parameter information is a representation of the current state of the elevator contactor, such as the state of the elevator contactor being in a healthy state or an abnormal state.
Wherein, the action voltage refers to the transient voltage and the steady-state voltage of the contact of the elevator contactor when the contact is closed or closed. Usually, at the moment when the contacts of the elevator contactor are closed or opened, a certain transient voltage is generated due to the action of the motor, and the transient voltage has certain influence on the elevator contactor. The contact abnormal frequency refers to the times that the contacts of the elevator contactor cannot be normally closed or normally turned off within a period of time. Referring to fig. 4, the contact resistance value refers to a resistance value of a resistor between a power source and a contact of an elevator contactor. The long-term use of the elevator contactor can cause the resistance value of the contact resistor to change to a certain extent. The action response time refers to the time between the generation of a command for closing or opening the contact of the elevator contactor and the completion of closing or opening the contact of the elevator contactor. The action response time can reflect the sensitive state of the elevator contactor to a certain extent. For example, when a new elevator contactor is replaced, the response time of the operation of the elevator contactor is obviously shorter than the corresponding time of the operation of the elevator contactor after a period of use. Referring to fig. 4, when the three MOS transistors above are turned on in a contact closed state of the elevator contactor, the electrode rotates in a positive direction; when the lower three MOS tubes are conducted, the elevator rotates in the negative direction; the elevator can be controlled up or down.
In specific implementation, the elevator control system can acquire the state parameter information of the elevator contactor with preset parameter dimensionality through a sampling board or a main board. Of course, different acquisition modes can be adopted according to different dimensions, and are not particularly limited herein. For example, when the action voltage and the contact resistance value of the elevator contactor are collected, the action voltage and the contact resistance value can be collected in a mode of connecting a universal meter; when the contact abnormal frequency is collected, the contact abnormal frequency can be determined by extracting the abnormal times of the contact in a certain time period and the ratio of the abnormal times to the time; when the action response time is collected, timing acquisition can be carried out by utilizing the timing device in the process of sending a pull-in or break-out command until the contact of the elevator contactor finishes pull-in or break-out.
Step S20: and carrying out state evaluation on the elevator contactor by using a preset state evaluation model according to the state parameter information to obtain a state evaluation result of the elevator contactor.
It should be noted that the preset state evaluation model is a model for evaluating the current state of the elevator contactor according to the collected state parameter information of the elevator contactor. The state evaluation result of the elevator contactor may be an evaluation result of the state of the elevator contactor in a healthy state or a state evaluation result of the state of the elevator contactor in an abnormal state. The preset state evaluation model can compare the corresponding preset parameter threshold value when the elevator contactor is in a healthy state with the currently acquired state parameter information to determine the current state of the elevator contactor, of course, the preset state evaluation model can also be an evaluation model trained by a convolutional neural network or other related algorithms, and the preset state evaluation model can directly output the state evaluation result of the elevator contactor according to the input state parameter information.
In specific implementation, the elevator control system can preset a state evaluation model for the acquired state parameter information input value, and the preset state evaluation model carries out state evaluation on the elevator contactor according to the input state parameter information and outputs a state evaluation result.
In the embodiment, a contactor state evaluation method is provided, and the method acquires state parameter information of an elevator contactor according to a preset parameter dimension; and carrying out state evaluation on the elevator contactor by using a preset state evaluation model according to the state parameter information to obtain a state evaluation result of the elevator contactor. In the embodiment, the state parameter information of the elevator contactor is collected, and then the state of the elevator contactor is evaluated according to the collected state parameter information, so that the health state of the elevator contactor is evaluated to determine the working state of the elevator contactor.
Referring to fig. 5, fig. 5 is a flowchart illustrating a second embodiment of the method for evaluating the state of a contactor according to the present invention, and the second embodiment of the method for evaluating the state of a contactor according to the present invention is proposed based on the first embodiment illustrated in fig. 2.
In the second embodiment, the step S20 includes:
step S21: and determining the deviation degree of the state parameter information according to the state parameter information and a preset parameter threshold.
The preset parameter threshold is information which is preset and used for comparing with the current state parameter information of the elevator contactor. The preset parameter threshold may be determined based on the specific performance of the elevator contactor. When the preset parameter threshold is obtained, a certain time period can be selected in a certain period in the initial operation stage of a newly replaced elevator contactor, a state parameter information set of relevant dimensions in the time period is recorded, and the preset parameter threshold is obtained in an averaging mode. The state parameter information deviation degree refers to the degree of deviation between the currently acquired state parameter information and the preset state information of the elevator contactor in the standard state. In a healthy state of the elevator contactor, the deviation degree of the state parameter information is smaller than a certain range. For example, in the state of health of an elevator, the operating voltage of the elevator contactor is usually between 85% and 110% of the rated control power supply voltage; of course, if the degree of deviation of the operating voltage in the current state parameter information does not fall within the range, it is determined that the elevator contactor is in an abnormal state. Of course, the state parameter information of other dimensions also has a certain floating range, which is not described herein.
In a specific implementation, the elevator control system may acquire the deviation degree of the state parameter information by calculating the acquired state parameter information and a preset parameter threshold, and may also acquire the deviation degree by the calculation, which is not specifically limited herein.
Step S22: and performing state evaluation on the elevator contactor by using the preset state evaluation model according to the deviation degree of the state parameter information to obtain a state evaluation result of the elevator contactor.
In a specific implementation, the elevator control system can evaluate the deviation degree of the state parameter information of each dimension respectively, and certainly, the state parameter information of each dimension can be evaluated as a whole. In the evaluation process, information corresponding to the dimension with the largest deviation degree of the state parameter information can be selected for preferential evaluation, for example, when the deviation degree of the contact resistance value is 120% and the deviation degree of the action response time is 20%, the contact resistance value can be preferentially evaluated, the elevator contactor is determined to be in an abnormal state after the contact resistance value is evaluated, subsequent evaluation can be avoided, and the evaluation efficiency is improved. Of course, the setting of the health status ranges of the status parameter information of each dimension is different, and needs to be determined according to specific setting conditions, for example, when the deviation degree of the contact resistance value is 80% in the health range, and the deviation degree of the action response time is 40% in the abnormal range, the evaluation of the deviation degree of the contact resistance value is not accurate preferentially, and in the specific evaluation, the setting can be determined according to the conditions.
In this embodiment, before the step S21, the method further includes:
step S211': and acquiring a state parameter information set of the elevator contactor within a preset time.
It should be noted that the preset time refers to a preset selected operation time under the condition that the normal operation time of the elevator contactor is short. The state parameter information acquired under the running state of the newly replaced elevator contactor is more accurate, the state parameter information of the elevator contactor running for a long time may have a certain deviation, and the acquired state parameter set is not accurate. The state parameter information set refers to a set formed by all state parameter information collected within a preset time.
In specific implementation, the state parameter information of the elevator contactor in the initial operation state, namely short operation time, in a preset period of time can be collected and stored to obtain a state parameter information set.
Step S212': and calculating the average value of the state parameters of the same parameter dimension in the state parameter information set, and setting a preset parameter threshold according to the average value.
It should be noted that, considering that the status parameter information collected instantaneously may have a certain contingency, the average value of the status parameter information collected over a period of time may more accurately represent the preset parameter threshold value of the elevator contactor. In the specific implementation process, the elevator control system can take the average value of the parameters in the collected state parameter information as a preset parameter threshold value, so that the state of the elevator controller can be more accurately evaluated.
In this embodiment, the step S21 includes:
step S211: and acquiring a preset parameter threshold corresponding to the state parameter of the same parameter dimension according to the preset parameter dimension.
It should be noted that the same parameter dimension refers to a parameter with the same dimension in the state parameter information and the preset parameter threshold. For example, an operating voltage in the state parameter information and an operating voltage in the preset state parameter information. Before calculating the deviation degree of the state parameter information, the state parameter information with the same dimensionality needs to be in one-to-one correspondence with a preset parameter threshold.
Step S212: and comparing the state parameter information with the preset parameter threshold value to determine the deviation degree of the state parameter information.
Note that, the degree of deviation of the state parameter information includes: the degree of deviation of the operating voltage, the degree of deviation of the contact point abnormal frequency, the degree of deviation of the contact resistance value, and the degree of deviation of the operating response time. In the specific implementation process, the degree of deviation between the action voltage in the state parameter information and the action voltage in the preset parameter threshold, the degree of deviation between the contact abnormal frequency in the state parameter information and the contact abnormal frequency in the preset parameter threshold, the degree of deviation between the contact resistance value in the state parameter information and the contact resistance value in the preset parameter threshold, and the degree of deviation between the action response time in the state parameter information and the action response time in the preset parameter threshold can be respectively calculated.
In the embodiment, a contactor state evaluation method is provided, and the method acquires state parameter information of an elevator contactor according to a preset parameter dimension; and carrying out state evaluation on the elevator contactor by using a preset state evaluation model according to the state parameter information to obtain a state evaluation result of the elevator contactor. In the embodiment, the state parameter information of the elevator contactor is collected, and then the state of the elevator contactor is evaluated according to the deviation degree of the collected state parameter information and the preset state information under each dimensionality, so that the health state of the elevator contactor is evaluated more accurately to determine the working state of the elevator contactor.
Referring to fig. 6, fig. 6 is a schematic flow chart of a contactor state evaluation method according to a third embodiment of the present invention, and the third embodiment of the contactor state evaluation method according to the present invention is proposed based on the second embodiment shown in fig. 5.
In the third embodiment, before the step S22, the method further includes:
step S221': and acquiring the state parameter health deviation degree of the elevator contactor in a normal state.
It should be noted that, in a normal operation state of the elevator contactor, the state parameter information is not a fixed value, and the state parameter information may fluctuate within a certain range around a standard preset parameter threshold, and the fluctuating state parameter information within the range may be regarded as a normal state parameter. The state parameter health deviation degree refers to the deviation degree between the state parameter information acquired in the normal state and a preset parameter threshold value. The normal deviation degree of the operating voltage is between 85% and 110%, the operating voltage in the range can be regarded as the normal operating voltage, and the range of 85% to 110% is the state parameter health deviation degree. The degree of deviation of the contact abnormal frequency may be that contact abnormality occurs twice in one month, and the specific degree of deviation of the contact abnormal frequency may be set according to the performance of the elevator contactor. The degree of deviation of the contact resistance values may be such that the main contact resistance value deviation does not exceed 100%. The degree of deviation of the corresponding time of the motion may be within 30% of the response time of the motion in the standard state.
In a specific implementation, the elevator control system can extract the range of the state parameter health deviation degree stored before the elevator contactor is used, or can acquire the state parameter health deviation degree by identifying the tag of the elevator contactor, and the parameter use range of the equipment is generally marked on the tag of the equipment.
Accordingly, the step S22 includes:
step S22': and performing state evaluation on the elevator contactor according to the deviation degree of the state parameter information and the state parameter health deviation degree to determine a state evaluation result of the elevator contactor.
It should be noted that, when the contactor state is evaluated, the preset state evaluation model may compare the deviation degree of the currently acquired state parameter information with the state parameter health deviation degree, and when the deviation degree of the state parameter information is within the state parameter health deviation degree range, the elevator contactor may be determined to be in a normal state, otherwise, the elevator contactor may be determined to be in an abnormal state.
In this embodiment, the step S22' includes:
step S221: and determining the deviation degree of the state parameters with the same parameter dimensionality according to the deviation degree of the state parameter information.
Step S222: and determining the state parameter health deviation degree of the same parameter dimension according to the state parameter health deviation degree.
It should be noted that the deviation degree in the state parameter information includes the state parameter deviation degrees of a plurality of parameter dimensions; the state health parameter deviation degrees also comprise state health parameter deviation degrees of multiple parameter dimensions, and before the state of the elevator contactor is evaluated, the deviation degrees of state parameter information of the same dimension need to be respectively corresponding to the state health parameter deviation degrees. For example, the degree of deviation of the motion response time in the state parameter information may be determined, the degree of deviation of the health motion response time in the state health parameter deviation degree may be determined, the degree of deviation of the motion response time obtained after the determination may be associated with the degree of deviation of the health motion response time, and then the motion response time state may be evaluated. The deviation degree of the state parameter information of other dimensions is also not described herein.
Step S223: and when the deviation degree of the state parameters with the same parameter dimensionality is in the numerical range corresponding to the state parameter health deviation degree with the same parameter dimensionality, judging that the elevator contactor is in a normal state, otherwise, judging that the elevator contactor is in an abnormal state.
It should be noted that the state of the elevator contactor needs to be determined according to the deviation degree of the state parameter information of each parameter dimension, and considering the particularity of the elevator contactor, the state parameter of a single parameter dimension can cause potential safety hazard to the normal operation of the elevator, so that when the state of the elevator is evaluated, the deviation degree of each parameter dimension needs to be evaluated, and when the deviation degrees of all the parameter dimensions meet the numerical range corresponding to the state parameter health deviation degree, the elevator contactor can be determined to be in a normal state. And when the deviation degree of the state parameter information of any one or more dimensions does not meet the numerical range corresponding to the state parameter health deviation degree, the elevator contactor is determined to be in an abnormal state.
In specific implementation, the elevator control system can compare the deviation degree of the state parameter of each parameter dimension with the value range corresponding to the state parameter health deviation degree to obtain the comparison result of each dimension, and when the comparison result of each dimension meets the condition of the state parameter health deviation degree, the elevator contactor is judged to be in a normal state, otherwise, the elevator contactor is judged to be in an abnormal state. In the concrete contrast process, the comparison can be respectively carried out according to the difference of the parameter dimension, when the deviation degree of the state parameter of one parameter dimension does not meet the condition of the state parameter health deviation degree, the elevator contactor is directly judged to be in an abnormal state, the subsequent contrast process is not needed, and the efficiency of judging the state of the elevator contactor is improved.
In this embodiment, after the step S222, the method further includes:
step S30: and when the elevator contactor is in an abnormal state, acquiring abnormal state parameter information from the state parameter information.
When the elevator contactor is in an abnormal state, it is necessary to feed back parameter information of a parameter dimension in the abnormal state so as to maintain or replace the elevator contactor. The abnormal state parameter refers to a state parameter of which the deviation degree of the state parameter information exceeds the health deviation degree of the state parameter. In a specific implementation process, the elevator control system can acquire abnormal state parameter information according to a result obtained by comparing the deviation degrees of the state parameter information.
Step S40: and generating abnormal prompt information according to the abnormal state parameter information, and sending the abnormal prompt information to a maintenance worker so that the maintenance worker can maintain the elevator contactor.
The abnormality indication information is information for indicating that the elevator contactor is in an abnormal state. In a specific implementation, the abnormal state information may be displayed through a display interface, which may be a nixie tube display unit. Referring to fig. 7, the abnormal state information can be sent to a server or a terminal device through the internet of things and displayed through the server or the terminal device, and maintenance personnel can maintain or replace the elevator contactor when receiving the display information.
In this embodiment, the number of times of switching on and off the elevator contactor may also be recorded for evaluating the quality of the elevator contactor, and of course, when a new elevator contactor is replaced, a reference may be set for the evaluation of the state of the elevator contactor according to the number of times of switching on and off the elevator contactor before. For example, a normal elevator contactor generates an abnormality after being turned on and off for 30 ten thousand times, and the state evaluation frequency of the elevator contactor can be increased after the replaced elevator contactor is used for 30 ten thousand times, so that the abnormal elevator contactor can be found timely.
In the embodiment, a contactor state evaluation method is provided, and the method acquires state parameter information of an elevator contactor according to a preset parameter dimension; and carrying out state evaluation on the elevator contactor by using a preset state evaluation model according to the state parameter information to obtain a state evaluation result of the elevator contactor. According to the embodiment, the state parameter information of the elevator contactor is collected, and then the state of the elevator contactor is evaluated according to the deviation degree of the collected state parameter information and the preset state information under each dimensionality, so that the health state of the elevator contactor is evaluated more accurately to determine the working state of the elevator contactor, and in the abnormal condition of the elevator contactor, abnormal prompt information is generated to enable maintenance personnel to timely maintain or replace the elevator contactor.
Furthermore, an embodiment of the present invention further provides a storage medium, on which a contactor state evaluation program is stored, and the contactor state evaluation program, when executed by a processor, implements the steps of the contactor state evaluation method as described above.

the information acquisition module 10 is used for acquiring state parameter information of the elevator contactor root under a preset parameter dimension;
