It may further comprise means for communicating with the safety manager of the elevator.

The signal input through the control panel 101 is transmitted to the operation control unit 190. The operation control unit 190 controls the car driving unit 150 according to the input control signal.

The car drive unit 150 includes a wire rope 151, a fixed drum 153, a car shock absorber 155, and the like. As described above, the car driving unit 150 includes related components for operating the elevator car 110 under the control of the operation control unit 190 according to the input of the control panel 101 in the elevator car 110, ). ≪ / RTI > The car drive unit 150 may include all conventional known elevator operation and safety configurations in addition to the structures of the wire rope 151, the fixed pulley 153, the car shock absorber 155, and the like.

The sensing unit 200 senses an operating state and an operating environment of the elevator car and the car driving unit. Specifically, the sensing unit may include a diagnostic sensor 201, a vibration sensor 203, and a noise sensor 205.

Referring to FIG. 3, the diagnostic sensor 201 diagnoses the degree of aging and stability of each part included in the elevator car 110 and the car drive unit 150. FIG. Conventionally, various diagnostic sensors have been developed and can detect abnormal symptoms or failures of various parts using such sensors.

The vibration sensor 203 detects the horizontal vibration and the vertical vibration of the elevator car, respectively. In the case of horizontal vibration, it can be detected by measuring horizontal movement or vibration of the wire rope supporting the elevator car. In case of vertical vibration, continuous weight change can be detected by using a weight sensor or the like, It is possible to detect the impact by measuring the impact.

The noise sensor 205 may include a first noise sensor for measuring the noise in the elevator car and a second noise sensor for measuring the noise outside the elevator car, particularly noise generated when the car drive unit 150 is driven.

The data sensed by the first noise sensor can be used as data for predicting the occurrence of an accident or an accident in the elevator by measuring the noise in the elevator. The data sensed by the second noise sensor is generated during the operation of the car driving unit And can be used as data for predicting safety related to the operation of the elevator.

The sensing unit 200 transmits the sensed data to the operation control unit 190 so that the sensed data can be used as data for operation of the conventional safety management system or transmitted to the safety management unit 300, The safety of the elevator can be managed according to the operation process of the elevator.

The safety management unit 300 includes a safety management control unit 301, a pattern comparison unit 303, and a pattern combination unit 305 as shown in FIG. The safety management unit 300 receives various types of data from the operation control unit 190, the elevator 100 and the sensing unit 200 and receives various data from the sensing unit 200. The safety management unit 300 determines whether the elevator 100 is safe or not, And performs necessary measures for safety management of the elevator 100.

For this, the safety management unit 300 may include databases for storing various data in advance. Specifically, the safety management unit 300 may include a reference pattern database, a failure history database, and a parts management database.

The reference pattern database can store two types of data. First, the reference pattern database may store reference pattern data for each type of occurrence faults that may occur in parts related to the elevator car driving unit, and may also store reference pattern data for each predetermined incident type.

Here, the reference pattern data for each type of failure is defined as one factor of the amplitude of the data relating to the horizontal vibration and the vertical vibration of the elevator car, and the amplitude of the data relating to the noise generated from the driving unit, And stored.

The reference pattern data for each type of accident may be stored in the form of preset pattern data for each type of safety accident or event that may occur in the elevator car. For example, it is possible to pre-pattern and store the occurrence of vibration of the emergency patient and the noise in the elevator car, to store the pattern of vibration and noise in advance according to the type of the strong case, It can be used as reference data for the judgment of the case. Also, in case of incidents or accidents, the measurement data of the sensing unit described above can be used again as reference pattern data for each type of accident.

In the failure history database, the existing failure history and the repair history are stored. In the parts management database, the history data of the parts for which the replacement, repair exchange, and the like are completed are stored for the corresponding failure history.

The pattern combination unit 305 performs a function of combining data transmitted from the operation control unit 190, the sensing unit 200 and the elevator 100 into pattern data so that the data can be compared with the data stored in the reference pattern database .

The pattern comparison unit 303 compares the reference pattern data with the pattern data combined after the measurement to determine whether there is a failure or the like, or whether there is an event / accident. It is preferable that the data stored in the pattern combining unit 305 and the reference pattern database are converted into a single pattern data rather than a plurality of data. That is, instead of comparing the vibration data and the noise data individually, the pattern data is converted into one pattern data, for example, image data based on a graph, so that comparison of the patterns and comparison by the pattern combining unit 305 . That is, the pattern combining unit 305 does not determine whether each individual data value is matched, but converts pattern data formed by a plurality of data, and then calculates a matching probability between the reference pattern data and the measured pattern data desirable.

That is, the pattern combining unit 305 combines the horizontal vibration and vertical vibration data of the elevator car inputted from the sensing unit 200 and the noise signals generated from the car driving unit inputted from the first and second noise sensors, And the pattern comparing unit 303 compares the combined pattern data with predetermined reference pattern data to determine whether there is an abnormality in the elevator or whether it is an accident in the elevator.

The pattern comparison unit 303 compares the combined pattern data with the reference pattern data for each failure type to estimate the failure type of the elevator corresponding to the combined pattern data. And the degree of stability of the elevator can be calculated or corrected based on the estimated probability of the elevator failure type. In addition, the pattern comparison unit 303 can correct the probability by reflecting information on failure histories and parts replacement corresponding to the fixed type estimated from the failure history database and the parts management database. At this time, it is possible to increase the probability that the period after the replacement has elapsed, or the component with frequent failure or replacement is proportional.

The pattern comparator 303 can also compare the combined pattern data with the reference pattern data and estimate the type of accidents in the elevator corresponding to the combined pattern data.

In this manner, reference pattern data related to various faults or failure indications and reference pattern data related to an event / accident are provided in advance, and the measured data are combined into pattern data and compared with each other. It is also possible to manage the safety outside the elevator configuration, such as accidents.

The safety management control unit 301 can notify a specific person in charge if a determination result of the pattern comparison unit 303 indicates a specific failure type or a type of an accident with a certain probability or more. For example, when a specific fault occurs or an indication of a fault is detected, it can be notified to the elevator manager. If the probability of occurrence of a specific event or accident is calculated to be more than a predetermined value, It is possible to notify the security officer or the manager.

Also, the safety management controller 301 may not provide or provide the data input from the information providing unit 400 to the elevator car depending on the situation. For example, when it is assumed that a situation such as a breakdown has occurred, it is possible to provide action information corresponding to a breakdown together with image information collected through an external CCTV or the like to the inside of the elevator, When the abnormality probability is calculated, provision of information to the inside is temporarily blocked, and the situation inside the elevator can be actively provided to the manager or the like.

On the other hand, a manager or the like can use a smart phone equipped with an application that can positively utilize the function of the safety management unit 300. As described above, the safety management controller 301 can transmit specific information to a smartphone corresponding to a safety manager or a security manager when a specific situation occurs. It is also possible for the safety management controller 301 to transmit specific information from the smart phone of the manager to the elevator operation and information input / You can do this by receiving instructions.

That is, even in the case of the safety manager or the security manager, even if the telephone number of the personal terminal of the passenger is unknown, the control panel or the information providing means in the elevator car is utilized by accessing the safety management controller 301 through the application of the smart phone You can try to communicate.
