Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Referring to FIG. 1 , FIG. 1 is a schematic structural diagram of a contactor state evaluation device in a hardware operating environment involved in the solution of an embodiment of the present invention.

As shown in FIG. 1 , the contactor state evaluation device may include: a processor 1001 , such as a central processing unit (Central Processing Unit, CPU), a communication bus 1002 , a user interface 1003 , a network interface 1004 , and a memory 1005 . Wherein, the communication bus 1002 is used to realize connection and communication between these components. The user interface 1003 may include a display screen (Display). The optional user interface 1003 may also include a standard wired interface and a wireless interface. The wired interface of the user interface 1003 may be a USB interface in the present invention. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-Fidelity (Wireless-Fidelity, WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM), or a stable memory (Non-volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001 .

Those skilled in the art can understand that the structure shown in Figure 1 does not constitute a limitation to the contactor state evaluation device, and may include more or less components than shown in the illustration, or combine certain components, or arrange different components .

As shown in FIG. 1 , the 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 Figure 1, the network interface 1004 is mainly used to connect to the background server, and to perform data communication with the background server; the user interface 1003 is mainly used to connect to user equipment; the contactor state evaluation device passes The processor 1001 calls the contactor state evaluation program stored in the memory 1005, and executes the contactor state evaluation method provided by the embodiment of the present invention.

Based on the above hardware structure, an embodiment of the contactor state evaluation method of the present invention is proposed.

Referring to FIG. 2 , which is a schematic flow chart of the first embodiment of the contactor state assessment method of the present invention, the first embodiment of the contactor state assessment method of the present invention is proposed.

In the first embodiment, the contactor state assessment method includes the following steps:

Step S10: Collect the state parameter information of the elevator contactor root in the preset parameter dimension.

It should be understood that the execution subject of this embodiment may be an elevator control system. The elevator control system includes a sampling board or main board and a microprocessor unit for information collection. The elevator control system can be a system composed of sensors or sampling boards connected to processing equipment such as single-chip microcomputers, ARMs, or even computers and servers. Referring to Figure 3, the specific connection relationship between sampling boards or main boards, elevator contactors, and power supplies.

It should be noted that the preset parameter dimension refers to a preset parameter dimension. The preset parameter dimension may include: status parameter information of the elevator contactor such as operating voltage, contact abnormal frequency, contact resistance value and action response time. Wherein, the state parameter information of the elevator contactor refers to parameter information used to reflect the current state of the elevator contactor. The state parameter information is a reflection of the current state of the elevator contactor, for example, the elevator contactor is in a healthy state or in an abnormal state.

Among them, the operating voltage refers to the transient voltage and steady-state voltage when the contacts of the elevator contactor are pulled in or turned off. Usually, at the moment when the contacts of the elevator contactor are closed or disconnected, a certain transient voltage will be generated due to the action of the motor, and the transient voltage will have a certain impact on the elevator contactor. Contact abnormal frequency refers to the number of times that the contacts of the elevator contactor fail to close or close normally within a period of time. Referring to Fig. 4, the contact resistance value refers to the resistance value between the power supply and the elevator contactor contact. The long-term use of the elevator contactor will cause a certain change in the contact resistance value. The action response time refers to the time between the command of the contact of the elevator contactor to make or break and the time between the completion of the contact of the elevator contactor to make or break. The action response time can reflect the sensitive state of the elevator contactor to a certain extent. For example, when replacing a new elevator contactor, the action response time of the elevator contactor is obviously shorter than that of the elevator contactor after a period of use. Referring to Figure 4, when the contacts of the elevator contactor are closed, when the upper three MOS tubes are turned on, the electrodes rotate in the positive direction; when the lower three MOS tubes are turned on, the elevator rotates in the negative direction; the elevator can be controlled to go up or down .

In a specific implementation, the elevator control system can collect the state parameter information of the elevator contactor in the preset parameter dimension through the sampling board or the main board. Of course, different acquisition methods may be adopted according to different dimensions, which are not specifically limited here. For example, when collecting the action voltage and contact resistance value of the elevator contactor, you can collect the action voltage and contact resistance value by connecting a multimeter; when collecting the abnormal frequency of the contact, you can extract a certain The number of contact abnormalities in the time period, the abnormal frequency of the contact is determined by the ratio of the number of abnormal occurrences to the time; when collecting the action response time, it can be determined by sending the pull-in or disconnection command until the elevator contactor The timing device is used for timing acquisition when the contact completes the pull-in or disconnection process.

Step S20: Perform state evaluation on the elevator contactor using a preset state evaluation model according to the state parameter information, and obtain a state evaluation result of the elevator contactor.

It should be noted that the preset state evaluation model is a model used to evaluate the current state of the elevator contactor according to the collected state parameter information of the elevator contactor. The status evaluation result of the elevator contactor may be the evaluation result that the elevator contactor is in a healthy state or the evaluation result that the elevator contactor is in an abnormal state. The preset state evaluation model can use the corresponding preset parameter threshold when the elevator contactor is in a healthy state to compare with the currently collected state parameter information to determine the current state of the elevator contactor. Of course, the preset state evaluation model can also be convoluted The evaluation model trained by the neural network or other related algorithms, the preset state evaluation model can directly output the state evaluation result of the elevator contactor according to the input state parameter information.

In a specific implementation, the elevator control system can input the collected state parameter information into a preset state evaluation model, and the preset state evaluation model evaluates the state of the elevator contactor according to the input state parameter information, and outputs a state evaluation result.

In this embodiment, a contactor state evaluation method is provided, the method collects the state parameter information of the elevator contactor according to the preset parameter dimension; according to the state parameter information, the preset state evaluation model is used to perform an evaluation on the elevator contactor A state evaluation obtains a state evaluation result of the elevator contactor. In this embodiment, the state parameter information of the elevator contactor is collected, and then the state evaluation of the elevator contactor is performed according to the collected state parameter information, thereby realizing the evaluation of the health state of the elevator contactor and determining the working state of the elevator contactor .

Referring to FIG. 5 , FIG. 5 is a schematic flowchart of the second embodiment of the contactor state assessment method of the present invention. Based on the first embodiment shown in FIG. 2 above, the second embodiment of the contactor state assessment method of the present invention is proposed.

In the second embodiment, the step S20 includes:

Step S21: Determine the degree of deviation of the state parameter information according to the state parameter information and a preset parameter threshold.

It should be noted that the preset parameter threshold refers to preset information for comparison with the current state parameter information of the elevator contactor. The preset parameter threshold can be determined according to the specific performance of the elevator contactor. When the preset parameter threshold is obtained, the newly replaced elevator contactor can select a certain period of time in a certain period during the initial operation stage, record the state parameter information set of the relevant dimension in the period, and take the average value Get the preset parameter threshold. The degree of deviation of state parameter information refers to the degree of deviation between the currently collected state parameter information and the preset state information of the elevator contactor in the standard state. When the elevator contactor is in a healthy state, the degree of deviation of the state parameter information is less than a certain range. For example, in the healthy state of the elevator, the action voltage of the elevator contactor is usually between 85% and 110% of the rated control power supply voltage; of course, when the deviation degree of the action voltage in the current state parameter information does not belong to this range, It can be 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 will not be repeated here.

In a specific implementation, the elevator control system can obtain the degree of deviation of the state parameter information by calculating the collected state parameter information and the preset parameter threshold, and of course it can also be obtained by other methods, which are not specifically limited here.

Step S22: Using the preset state evaluation model to evaluate the state of the elevator contactor according to the degree of deviation of the state parameter information, and obtain a state evaluation result of the elevator contactor.

In a specific implementation, the elevator control system may evaluate the degree of deviation of the state parameter information of each dimension separately, and certainly may evaluate the state parameter information of each dimension as a whole. In the evaluation process, the information corresponding to the dimension with the largest deviation degree of the state parameter information can be selected for priority 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%, at this time, you can Prioritize the evaluation of the contact resistance value. After the evaluation of the contact resistance value, it has been determined that the elevator contactor is in an abnormal state, which can avoid subsequent evaluation and improve the efficiency of evaluation. Of course, the setting of the health state range of the state parameter information of each dimension is not the same, and it needs to be determined according to the specific setting situation. For example, the deviation degree of the contact resistance value is 80% in the healthy range, and the deviation degree of the action response time is 40% is in the abnormal range. At this time, it is inaccurate to evaluate the deviation degree of the contact resistance firstly, and it can be determined according to the actual situation during the specific evaluation.

In this embodiment, before the step S21, it also includes:

Step S211': Obtain a set of state parameter information of the elevator contactor within a preset time.

It should be noted that the preset time refers to the running time selected in advance when the normal working time of the elevator contactor is very short. The state parameter information obtained under the running state of the newly replaced elevator contactor will be more accurate, but the state parameter information of the elevator contactor after running for a long time may have a certain deviation, and the state parameter set collected at this time is not accurate. precise. The state parameter information set refers to a set composed of all state parameter information collected within a preset time.

In a specific implementation, the state parameter information of the elevator contactor in the initial running state, that is, the running time is very short, can be collected and stored within a preset period of time to obtain a set of state parameter information.

Step S212': Calculate the average value of the state parameters of the same parameter dimension in the state parameter information set, and set a preset parameter threshold according to the average value.

It should be noted that, considering that the state parameter information collected instantaneously may have a certain degree of contingency, the average value of the state parameter information collection collected within a period of time can more accurately represent the preset parameter threshold of the elevator contactor. In a specific implementation process, the elevator control system can take the average value of the parameters in the collected state parameter information as the preset parameter threshold, and can more accurately evaluate the state of the elevator controller.

In this embodiment, the step S21 includes:

Step S211: Acquire preset parameter thresholds corresponding to state parameters 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, the action voltage in the state parameter information and the action voltage in the preset state parameter information. Before calculating the degree of deviation of the state parameter information, it is necessary to make a one-to-one correspondence between the state parameter information of the same dimension and the preset parameter threshold.

Step S212: comparing the state parameter information with the preset parameter threshold to determine the degree of deviation of the state parameter information.

It should be noted 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 abnormal frequency, the degree of deviation of the contact resistance value, and the degree of deviation of the action 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 difference between the contact abnormal frequency in the state parameter information and the contact abnormal frequency in the preset parameter threshold can be calculated respectively. The degree of deviation between the contact resistance value in the state parameter information and the contact resistance resistance value in the preset parameter threshold value, and the difference between the action response time in the state parameter information and the action response time in the preset parameter threshold value degree of deviation.

In this embodiment, a contactor state evaluation method is provided, the method collects the state parameter information of the elevator contactor according to the preset parameter dimension; according to the state parameter information, the preset state evaluation model is used to perform an evaluation on the elevator contactor A state evaluation obtains a state evaluation result of the elevator contactor. In this embodiment, the state parameter information of the elevator contactor is collected, and then the state evaluation of the elevator contactor is performed according to the degree of deviation between the collected state parameter information and the preset state information in each dimension, thereby more accurately realizing Evaluate the health status of the elevator contactor to determine the working status of the elevator contactor.

Referring to FIG. 6 , FIG. 6 is a schematic flowchart of the third embodiment of the contactor state assessment method of the present invention. Based on the second embodiment shown in FIG. 5 above, the third embodiment of the contactor state assessment method of the present invention is proposed.

In the third embodiment, before the step S22, it also includes:

Step S221': Obtain the degree of health deviation of the state parameters of the elevator contactor in a normal state.

It should be noted that when the elevator contactor is in normal operation, the state parameter information is not a fixed value, and the state parameter information will fluctuate within a certain range centered on the standard preset parameter threshold value. All state parameter information can be identified as normal state parameters. The state parameter health deviation degree refers to the deviation degree between the state parameter information collected in the normal state and the preset parameter threshold. Generally, the deviation degree of the operating voltage is between 85% and 110%, and the operating voltage within this range can be regarded as a normal operating voltage, while the range of 85% to 110% is the degree of health deviation of the state parameters. The degree of deviation of the contact abnormality frequency can be that there are two contact abnormalities within one month. Of course, the specific deviation degree of the contact abnormality frequency can be set according to the performance of the elevator contactor. The degree of deviation of the contact resistance can be such that the deviation of the resistance of the main contact poles does not exceed 100%. The degree of deviation of the action response time may be within 30% of the action response time in the standard state.

In a specific implementation, the elevator control system can extract the range of the health deviation degree of the state parameter stored before the elevator contactor is used, or obtain it by identifying the label of the elevator contactor, usually on the label of the equipment. Mark the parameter usage range of the device.

Correspondingly, the step S22 includes:

Step S22': Perform a state evaluation of the elevator contactor according to the deviation degree of the state parameter information and the health deviation degree of the state parameter to determine the state evaluation result of the elevator contactor.

It should be noted that when evaluating the state of the contactor, the preset state evaluation model can compare the degree of deviation of the currently collected state parameter information with the degree of health deviation of the state parameter. Within the range, it can be considered that the elevator contactor is in a normal state, otherwise it can be considered that the elevator contactor is in an abnormal state.

In this embodiment, the step S22' includes:

Step S221: Determine the degree of deviation of the state parameters of the same parameter dimension according to the degree of deviation of the state parameter information.

Step S222: Determine the health deviation degree of the state parameter in the same parameter dimension according to the deviation degree of the state health parameter.

It should be noted that the degree of deviation in the state parameter information includes the degree of deviation of the state parameters of multiple parameter dimensions; the degree of deviation of the state health parameters also includes the degree of deviation of the state health parameters of multiple parameter dimensions. When evaluating the state of the elevator contactor Previously, it was necessary to correspond the degree of deviation of state parameter information of the same dimension to the degree of deviation of state health parameters. For example, the deviation degree of the action response time in the state parameter information can be determined, and then the deviation degree of the health action response time in the state health parameter deviation degree can be determined, and the deviation degree of the action response time obtained after determination is related to the health action response time Correspond to the degree of deviation, and then evaluate the state of action response time. The same is true for the degree of deviation of state parameter information in other dimensions and will not be described here.

Step S223: When the degree of deviation of the state parameters of the same parameter dimension is in the numerical range corresponding to the degree of health deviation of the state parameter of the same parameter dimension, it is determined that the elevator contactor is in a normal state; otherwise, it is determined that the elevator contactor is in a normal state. Abnormal state.

It should be noted that the state of the elevator contactor needs to be determined according to the degree of deviation of the state parameter information of each parameter dimension. Considering the particularity of the elevator contactor, the state parameters of a single parameter dimension will cause safety hazards to the normal operation of the elevator. Therefore, when evaluating the elevator state, it is necessary to evaluate the deviation degree of each parameter dimension. When the deviation degree of all parameter dimensions meets the value range corresponding to the health deviation degree of the state parameter, the elevator contactor can be considered to be in a normal state. When the degree of deviation of the state parameter information of any one or more dimensions does not meet the numerical range corresponding to the degree of health deviation of the state parameter, it is determined that the elevator contactor is in an abnormal state.

In a specific implementation, the elevator control system can compare the deviation degree of the state parameter in each parameter dimension with the numerical range corresponding to the state parameter health deviation degree, and obtain the comparison results of each dimension, and the comparison results in each dimension satisfy the state parameter health. When the condition of the degree of deviation is determined, it is determined that the elevator contactor is in a normal state, otherwise it is determined that the elevator contactor is in an abnormal state. In the specific comparison process, you can choose to compare the parameters according to the different dimensions. When the deviation degree of the state parameter of a parameter dimension does not meet the condition of the state parameter health deviation degree, it is directly determined that the elevator contactor is in an abnormal state. No need The follow-up comparison process is carried out to improve the efficiency of elevator contactor status determination.

In this embodiment, after the step S222, it also includes:

Step S30: when the elevator contactor is in an abnormal state, obtain abnormal state parameter information from the state parameter information.

It should be noted that when the elevator contactor is in an abnormal state, it is necessary to feed back the parameter information of the parameter dimension in the abnormal state, so as to maintain or replace the elevator contactor. The abnormal state parameter refers to the state parameter whose degree of deviation of state parameter information exceeds the degree of health deviation of the state parameter. In a specific implementation process, the elevator control system may obtain the abnormal state parameter information according to the result obtained after comparing the degree of deviation of the above state parameter information.

Step S40: Generate abnormal prompt information according to the abnormal state parameter information, and send the abnormal prompt information to maintenance personnel, so that the maintenance personnel can perform maintenance on the elevator contactor.

It should be noted that the abnormal prompt information is information for prompting that the elevator contactor is in an abnormal state. In a specific implementation, the abnormal state information can be displayed through a display interface, and the display interface can be a digital tube display unit. Referring to Figure 7, the abnormal state information can also be sent to the server or terminal device through the Internet of Things, etc., and displayed through the server or terminal device, and the maintenance personnel can repair or repair the elevator contactor when receiving the displayed information. replace.

In this embodiment, the number of opening and closing times of the elevator contactor can also be recorded for evaluating the quality of the elevator contactor. Of course, when replacing a new elevator contactor, it can be The number of opening and closing times sets the reference for the status evaluation of the elevator contactor. For example, a normal elevator contactor is abnormal after being turned on and off for 300,000 times. After the replacement elevator contactor can be used for 300,000 times, the frequency of status evaluation of the elevator contactor should be increased to ensure that abnormal elevators can be found in time. contactor.

In this embodiment, a contactor state evaluation method is provided, the method collects the state parameter information of the elevator contactor according to the preset parameter dimension; according to the state parameter information, the preset state evaluation model is used to perform an evaluation on the elevator contactor A state evaluation obtains a state evaluation result of the elevator contactor. In this embodiment, the state parameter information of the elevator contactor is collected, and then the state evaluation of the elevator contactor is performed according to the degree of deviation between the collected state parameter information and the preset state information in each dimension, thereby more accurately realizing Evaluate the health status of the elevator contactor to determine the working status of the elevator contactor, and generate an abnormal prompt message in the event of an abnormality in the elevator contactor so that maintenance personnel can maintain or replace the elevator contactor in a timely manner.

In addition, an embodiment of the present invention also proposes a storage medium, on which a contactor state evaluation program is stored, and when the contactor state evaluation program is executed by a processor, the method for evaluating the contactor state as described above is implemented. step.
