[0002] With the improvement of people's living standards, elevator has become the standard configuration of high-rise building, however, due to the influence of external factors and internal factors, the actual floor where the elevator is located is different from the floor judged by the elevator system, that is, the actual floor is inconsistent with the elevator display floor, that is, elevator mislevel.

[0003] After elevator mislevel occurs, continue to run, elevator roof or squat bottom phenomenon occurs, causing more serious elevator accident, personnel and property loss. At this time, the state needs to be detected and quickly automatically corrected floor, and then control the car door after the completion of the correction floor, to avoid elevator trapped and other accidents.

[0004] In the existing technology, if elevator mislevel phenomenon occurs, mainly through the following three kinds of schemes for correction: (1) the upper forced deceleration switch and the lower forced deceleration switch in the shaft are used as real floor markers, when the car runs in a certain direction, as long as the upper forced deceleration switch or the lower forced deceleration switch is detected, the corresponding system floor is reset to the top floor or the bottom floor; (2) an iron plate is added at the level position of each floor according to certain rules, and each iron plate corresponds to a fixed floor, when the car runs in a certain direction, if the iron plate corresponding to the floor is detected, the system floor is reset to the corresponding actual floor; (3) absolute value position sensor is used to record the real pulse position of elevator shaft, and the car is corrected to real floor by absolute value position sensor during running.

[0005] However, the above-mentioned correction method is single, however, there are many factors causing elevator mislevel, and the emergency degree of harm to the trapped personnel in the elevator is different, in addition, there are no people in the elevator, and the traditional correction method cannot adapt to the high development and high requirements of elevator field. SUMMARY

[0040] The following will be further described in detail through specific embodiments:

[0041] The embodiments are basically as shown in the accompanying drawings: Figure 1

[0042] An elevator floor correction method, comprising:

[0043] S1, obtaining normal operation data of the elevator; the normal operation data of the elevator is used as comparison data for fault identification, when the data of the elevator operation is different from the normal operation data, it can be judged that the elevator has a fault. The fault in the application includes external environment influence fault, mechanical system fault and electrical control system fault. The S1 comprises:

[0044] S11, obtaining image data outside the car when the elevator is normally running, obtaining environmental data outside the elevator car through image data analysis, and judging the external environment influence fault through the environmental data.

[0045] ​S12, obtaining the usage data of the elevator in normal operation, the usage data including: the floor of entering the elevator, the floor of leaving the elevator, the running direction, the running speed, and the load; through statistical analysis of the floor of entering the elevator, the floor of leaving the elevator, the running direction, the running speed, and the load, the most frequently used landing and the most efficient landing can be obtained, and the usage frequency and the usage efficiency are used as auxiliary data for judging the correction floor. Specifically, when multiple correction floors are matched, the landing with higher usage frequency is preferred for correction, and when the usage frequency still cannot match a unique floor, the landing with higher usage efficiency is preferred for correction.

[0046] S13, obtaining the running state of the mechanical system and the circuit state of the electrical control system of the elevator in normal operation. The running state of the mechanical system can be used to judge the mechanical failure of the elevator, and the mechanical system includes the traction system, the guide system, the car, the door system, the weight balance system, the power drive system, and the safety protection system. Through comparison of the above mechanical system states, the mechanical system failure of the elevator can be judged, such as lubrication failure, serious heating and wear or shaft holding at the rotating part of the component, which can cause damage to the parts at the rolling or sliding part; elevator use and consumption, wear and aging of some parts; part falling off, some fastening screws loosening or coming off due to vibration during elevator operation, causing abnormal movement of the elevator; imbalance of the elevator balance coefficient, overload, large car shaking, poor landing accuracy, and out-of-control speed. The circuit state of the electrical control system can be used to judge the electrical control system failure of the elevator, such as short circuit and open circuit.

[0047] S2, identifying whether the elevator has a failure according to the normal operation data, and identifying the failure when the elevator has a failure; the normal operation data includes the image data outside the car, the usage data, and the running state of the mechanical system and the circuit state of the electrical control system when the elevator is in normal operation, wherein the image data outside the car is the data for predicting the failure of the elevator; the usage data is used as the data for auxiliary analysis and judgment of whether the failure occurs; and the running state of the mechanical system and the circuit state of the electrical control system are the data for directly judging whether the failure of the elevator occurs and the failure. The S2 includes:

[0048] S21, obtaining the effective data for failure identification from the normal operation data, specifically, obtaining the associated running data of the elevator historical failure as the effective data for failure identification; for example, the historical failure A is the imbalance of the elevator balance coefficient, and the associated running data is the counterweight and weight compensation data and the traction drive data, then the counterweight and weight compensation data and the traction drive data are the effective data for failure identification, and the effective data corresponding to all historical failures is the data set for failure identification.

[0049] S22, identify whether the elevator has a fault, when the elevator has a fault, identify the fault based on the effective data. For example, when the counterweight and weight compensation data of the elevator, traction drive data is abnormal, that is, fault A can be identified.

[0050] S23, when a new elevator fault occurs, add the operation data associated with the new fault as the effective data for fault identification;

[0051] S24, when the historical fault is empty, add the initial effective data for fault identification, when the elevator is just put into use, there is no historical fault, at this time, the initial effective data for fault identification needs to be added. The initial effective data for fault identification in this embodiment is the effective data corresponding to the common fault of the same type of elevator.

[0052] S3, match the correction strategy according to the fault type, and correct the elevator according to the correction strategy. The S3 includes:

[0053] S31, preset the correction strategy, the correction strategy includes: correcting to the last floor, correcting to the next floor, correcting to the commonly used floor, and correcting to the nearest floor;

[0054] S32, classify the faults of the elevator according to the emergency degree, and match the fault types of each emergency degree with the correction strategy. As described above, the elevator faults include external environment influence faults, mechanical system faults, and electrical control system faults, each type of fault contains several sub-faults, and the emergency degree of the sub-faults is different. The more urgent the fault is, the faster it needs to be corrected, and the less urgent the fault is, the more the experience of the passengers in the elevator needs to be considered. The emergency degree is obtained by weighting the risk degree and risk development speed of the fault. The risk degree and risk development speed of several sub-faults have fixed assignments respectively, for example, the risk degree of the imbalance coefficient of the elevator is assigned as a1, and the risk development speed is a2, and the emergency degree is a1+a2. When multiple faults occur simultaneously, the emergency degree is accumulated. Each correction strategy corresponds to an emergency degree threshold interval, and the correction strategy is matched according to the emergency degree threshold interval.

[0055] The emergency degree includes high, medium and low, and the corresponding correction strategies are correcting to the nearest floor, correcting to the last / next floor, and correcting to the commonly used floor. When the emergency degree is high, the elevator is corrected to the nearest floor to provide more escape time for the passengers in the elevator; when the emergency degree is medium, the elevator is corrected to the last / next floor according to the running direction before the elevator fault, to reduce the time spent by the passengers after getting out of the elevator to reach the target floor and improve the experience; when the emergency degree is low, the elevator is corrected to the commonly used floor combined with auxiliary data, to correct to the target floor of the passenger with a higher probability.

[0056] In addition, the external environment influence fault includes disaster, light, number of people and floor occupancy; the disaster includes fire, flood, pest, and when the elevator is corrected, it is not corrected to the floor where the disaster is located, so as to avoid the secondary injury of passengers out of the elevator.

[0057] Similarly, it is not corrected to the floor where the light damage is located, so as to avoid the psychological panic of passengers in the elevator.

[0058] When there is no passenger in the elevator, the correction is made to the floor with more people at the elevator door.

[0059] When there is no one at the elevator door, the correction is made to the floor with the largest number of occupants. Specifically, the number of entries and the entry weight of the entry floor are analyzed in combination with the entry floor, the exit floor, the load of the elevator during normal operation, and the number of entries and the entry weight of each floor are scored in terms of usage degree every month, and the floor with the highest usage degree this month is considered as the floor with the largest number of occupants.

[0060] S33, correcting the elevator according to the matched correction strategy.

[0061] S4, collecting the expression, action and voice of the passenger in the elevator car through the camera in the elevator, and analyzing whether the passenger notices the wrong floor correction through the expression, action and voice of the passenger, and giving a voice reminder when the passenger notices the wrong floor correction. When someone notices that the elevator is being corrected, a voice reminder is given to explain the situation, so as to avoid passengers' random suspicion and panic; if no one notices that the elevator is being corrected, and the correction does not affect the user to reach the target floor, no voice reminder is given to reduce the panic of passengers.

[0062] An elevator wrong floor correction device, comprising a memory and a processor, the memory stores a computer program executable on the processor, and the processor implements the steps of the elevator wrong floor correction method when executing the computer program.

[0063] A computer readable storage medium, the computer readable storage medium stores a computer program, and the computer program is executed by a processor to implement the steps of the elevator wrong floor correction method.

[0064] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, some modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the description can be used to explain the content of the claims.
