  The present invention relates to an elevator travel data collection device that collects data during elevator travel.

  The elevator travel data collection device collects vibration data of a car generated during elevator travel from the viewpoint of investigating elevator ride comfort, travel vibration abnormality determination, travel vibration abnormality cause, etc. ing.

  Conventionally, the following two types of devices have been proposed for collecting vibration data generated during the traveling of an elevator.

  As shown in FIG. 8, one of the main ropes 53 wound around the main sheave 51 and the baffle sheave 52 is suspended from one end 54 and a counterweight 55 is suspended from the other end. When collecting the middle data, an acceleration sensor 56 is temporarily installed on the car floor in the car 54, and a measuring instrument 57 is connected to the acceleration sensor 56 so that the elevator travels from the data representing the acceleration detected by the acceleration sensor 56. The vibration of time is measured.

  That is, this vibration data measurement system extracts analog vibration data during elevator travel from the acceleration sensor 56 and supplies it to the measuring device 57. The measuring instrument 57 displays or prints out an analog vibration waveform output from the acceleration sensor 56, converts it into digital data as necessary, stores it, and writes it in a storage means such as a separate personal computer. It is used for analysis of running vibration.

  Such a data collection device during traveling is relatively expensive because the acceleration sensor 56 and the measuring instrument 57 are relatively expensive, and is often temporarily installed in an elevator cab and collects data. Absent.

  As shown in FIG. 9, the other one is an elevator operation control device 61, an acceleration sensor 63 that is permanently installed in the car 62, and a running state monitoring unit 64 that monitors the running state from the output of the acceleration sensor 63. Has been proposed (Patent Document 1).

  This elevator monitoring device constantly monitors the traveling vibration of the elevator. Specifically, in addition to the general operation control operation of the car 62, the elevator monitoring is accelerated, the steady running, and the deceleration. An elevator operation control device 61 that outputs acceleration state instruction information indicating time and the like, travel position instruction information indicating the current travel position of the car, and an acceleration sensor 63 that outputs an analog signal representing the acceleration of the car 62 during travel. And an analog signal representing acceleration output from the acceleration sensor 63 corresponding to the acceleration state instruction information and the car traveling position instruction information from the elevator operation control device 61, and converting the data into acceleration item-specific data. When the output data for each item converted by the data processing means 65 is evaluated and analyzed, and the running state is determined to be abnormal A determination unit 66 for generating abnormality information, a memory 67 for storing various format information, a memory 68 for storing the number of occurrences of abnormality information for each part, and storing an acceleration detection output at the time of occurrence of abnormality information, Output display means 69 for simultaneously displaying the read information and the format information of the memory 67 corresponding thereto is provided. Reference numeral 70 denotes a CPU that performs overall control of each component, and reference numeral 71 denotes a monitoring unit that stores information related to abnormality information and sends it to the terminal device 72.

That is, as this elevator monitoring device, the data processing means 65 classifies acceleration based on the acceleration state instruction information from the elevator operation control device 61, and obtains the acceleration obtained from the acceleration sensor 63 attached to the car 62. The data to be represented is output according to the item classification and sent to the determination means 66. The determination means 66 compares the output data obtained by dividing into items and a reference value, and issues abnormality information when the output data indicates an abnormal value.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 to FIG. 3 are diagrams for explaining a first embodiment of the present invention. FIG. 1 is an overall configuration diagram of an elevator to which a traveling data collection device is applied, and FIG. 2 is an example of installation of the traveling data collection device. FIG. 3 and FIG. 3 are functional configuration diagrams showing an embodiment of an elevator travel data collection apparatus according to the present invention.

  First, as an elevator, a main rope 2 is wound around a main sheave 1 connected to a rotating shaft of an electric motor (not shown), and a car 3 is suspended on one end side of the main rope 2. . On the other end side of the main rope 2, a counterweight 5 is suspended through a deflecting sheave 4 arranged at an appropriate position.

  As shown in FIG. 2, the car 3 is composed of a car frame 3a and a car room 3c supported by the car frame 3a via an elastic member 3b and the like, on the back side of the car floor 3d of the car room 3c. An acceleration sensor 11 as an acceleration detecting means that is detachably attached and detects and outputs analog data representing acceleration when the car is running, and can be removed on, for example, the car frame 3a that is close to the place where the acceleration sensor 11 is attached. A data collection / recording device 12 is installed which collects and records analog data representing acceleration and appropriately processing.

  The acceleration sensor 11 and the data collection / recording device 12 are attached to the rear surface side of the car floor 3d as described above. In this case, the acceleration sensor 11 and the data collection / recording device 12 can be completely fixedly installed, but are easily detachably attached. As an example of attaching the acceleration sensor 11 and the data collecting / recording device 12 so as to be easily detachable, for example, a U-shaped sensor mounting member 3e is fixedly installed on the back surface side of the car floor 3d, and screwed or otherwise fitted to the mounting member 3d. If the configuration is such that the acceleration sensor 11 is attached and the data collection / recording device 12 is temporarily temporarily installed on the lower frame of the car frame 3a, it can be detachably attached. It can be easily removed.

  As shown in FIG. 3, the data collection / recording apparatus 12 includes an A / D conversion means 12a for converting analog data representing acceleration detected by the acceleration sensor 11 into digital data and outputting the digital data, and a predetermined representing a state of deterioration in riding comfort. Is determined, and it is determined whether or not the digital data representing the acceleration converted by the A / D conversion means 12a exceeds the threshold value. It is determined that the vibration is in an uncomfortable riding state, that is, an abnormal state, and the data determination unit 12b outputs digital data representing the acceleration accompanied by the determination result, and the determination result indicating that the data determination unit 12b is in an abnormal state. If received, digital data representing acceleration in an abnormal state and date / time data including the hour and minute output from the clock function 12c. Recorded in the data recording storage means 12d having at least the abnormal data time history recording area 12da and the steady data recording area 12db, and if the digital data representing acceleration is below the threshold value and continues for a certain period of time, the data And data collection processing means 12e for interrupting the recording.

  As the data recording / storing means 12d, various recording media are used. Preferably, for example, a memory card, a hard disk device, an optical disk device, or the like that can be detachably loaded into the data collection / recording device 12 is used.

  In the steady state, the data collection processing means 12e sequentially stores the digital data converted by the A / D conversion means 12a in the steady data recording area 12db in time series, while the steady data recording area 12db is full. In such a case, the process of storing the latest data is executed while sequentially overwriting the recording area of the oldest data, and when a determination result indicating abnormality is received, the date and time data from the clock function 12c described above is previously stored. A process of recording data for a predetermined predetermined time in the abnormal data time history recording area 12da is performed, and data recording is interrupted when digital data representing acceleration is below a threshold value and continues for a certain period of time. .

  The data for the predetermined time is the boundary of the abnormality determination date and time, the data before 1/2 of the predetermined time is read from the steady data recording area 12db and transferred to the abnormal data time history recording area 12da, Further, for data after ½ of the predetermined time, the data output from the data determination means 12c is written as it is in the abnormal data time history recording area 12da together with the date / time data. It should be noted that data after a half of the predetermined time may be simultaneously written in the steady data recording area 12db.

  Next, the operation of the above apparatus will be described.

  When collecting traveling data during elevator traveling, the acceleration sensor 11 and the data collecting / recording device 12 are attached to the rear surface of the car floor 3d and the car frame 3a of the car room 3c, and then operated by an elevator control panel (not shown) or the like. Drive the elevator based on the instructions. At this time, the acceleration sensor 11 detects the acceleration of the car floor 3d, detects analog data representing the acceleration, and sends it to the data collection and recording device 12.

  The data collection / recording apparatus 12 converts analog data representing acceleration detected by the acceleration sensor 11 by the A / D conversion means 12a into digital data and sends the digital data to the data determination means 12b. The data determination means 12b compares the digital data with a predetermined threshold value, and if the digital data is within the threshold value, notifies the data collection processing means 12e that the running data is in a steady state. Here, when the data collection processing means 12e receives the fact that it is in a steady state, it sequentially records the digital data sent from the data determination means 12b in the steady data recording area 12db of the data recording / storing means 12d. When the state is reached, the data is overwritten by returning to the first data area, and the recording capacity of the data recording storage means 12d is reduced.

  On the other hand, when the data determination unit 12b determines that the digital data has exceeded the threshold value, the determination result indicating that the running is abnormal and the digital data are sent to the data collection processing unit 12e. Here, the data collection processing means 12e takes in the date / time data including the hour and minute output from the clock function 12c, and records it in the abnormal data time history recording area 12da together with the digital data from the data determination means 12b for a predetermined time. At this time, time history data is created by reading out data before half the predetermined time from the steady data recording area 12db and transferring it to the abnormal data time history recording area 12da.

  The data collection processing unit 12e then stops data collection and recording in the abnormal data time history recording area 12da and sequentially records only in the steady data recording area 12db when a predetermined time has elapsed after the abnormality determination.

  Therefore, according to the above-described embodiment, when the driving data is in an abnormal state, the acceleration data and the date / time data are simultaneously recorded, so that the vibration during the elevator driving, the driving pattern of the elevator control panel, the driving speed, and the stop It is possible to collate with operation data such as floor and door opening and closing, and it is possible to accurately investigate the cause of abnormal vibration.

  Further, since the acceleration sensor 11 and the data collecting / recording device 12 are detachably installed in the car 3, it can be used for a large number of elevators, so that the cost can be greatly reduced, and the necessary period It is only necessary to collect travel data, and since the travel data in the steady state is recorded in the steady data recording area 12d and overwritten sequentially when it is full, the data record storage means 12d can be realized with a small storage capacity, and is always the latest It can hold driving data.

  Furthermore, when the running data is in an abnormal state, the running data for a predetermined time is recorded in the abnormal data time history recording area 12da together with the date and time data, so only the time history data in the recording area needs to be read out for analysis. Therefore, necessary data can be extracted promptly.

  Furthermore, unlike the conventional vibration measurement by the former measuring instrument, this apparatus allows a general passenger to use an elevator even during measurement.

  Further, when the acceleration data exceeds a predetermined threshold value, it is recorded including data for a time corresponding to, for example, 1/2 of a predetermined time before that, and after that, the acceleration data falls below the predetermined threshold value. If data recording to the abnormal data time history recording area 12da is interrupted for a predetermined time or longer, unnecessary data is not recorded and the data recording amount can be reduced.

  In the above-described embodiment, a predetermined threshold value set in advance is set and compared with acceleration data. However, this predetermined threshold value can be changed locally, and an abnormality in traveling vibration is detected. In accordance with the purpose of investigating the cause, etc., it will be changed appropriately at the site.

  This embodiment is characterized in that an acceleration sensor 11 and a data collection / recording device 12 are installed as acceleration detection means for detecting and outputting analog data representing acceleration when the car is traveling on the back side of the car floor 3d of the car 3. It is the same as that of the first embodiment except that a noise meter 21 as noise detecting means is detachably mounted in the car 3.

  The configuration of the sound level meter 21 includes, for example, an omnidirectional pressure microphone that outputs a voltage proportional to sound pressure, an amplification output means that amplifies and outputs a minute voltage output from the microphone to a required level, and the like. That is, it has a function of outputting analog data representing noise.

  On the other hand, the data collection and recording device 12 is provided with A / D conversion means 12a and 12f corresponding to the output side of the acceleration sensor 11 and the sound level meter 21, respectively, and the acceleration converted by these A / D conversion means 12a and 12f. The analog data representing noise is converted into digital data representing acceleration and noise, respectively, and sent to the subsequent data determination means 12b.

  The data determination means 12b is set in advance with thresholds determined in advance according to acceleration and noise, respectively, and individually compares with digital data representing acceleration and noise. When the digital data exceeds the threshold, It has a function of determining an abnormal state in either one or both of acceleration and noise.

  The data collection / recording device 12 is provided with data recording / storing means 12d. The data recording / storing means 12d is divided into areas for acceleration and noise as described above, and abnormal data time history recording for acceleration is provided. In addition to the area 12da and the steady data recording area 12db, an abnormal data time history recording area 12dc for noise and a steady data recording area 12dd are provided. The acceleration abnormal data time history recording area 12da and the noise abnormal data time history recording area 12dc may be a single recording area. This is because the abnormal data recording contents of acceleration and noise can be easily grasped.

  Further, the data collection processing means 12e takes in the date / time data including the hour and minute output from the clock function 12c based on the abnormality determination result from the data determination means 12b, and performs abnormality for a predetermined time together with the digital data from the data determination means 12b. The point of recording in the data time history recording area 12da and the like is the same as in the first embodiment. Note that the recording process to the data recording / storing unit 12d by the data collection processing unit 12e is the same as that in the first embodiment, and is omitted here.

  Next, the operation of the above apparatus will be described.

  After the acceleration sensor 11, the data collection and recording device 12 and the sound level meter 21 are detachably installed on the back side of the car floor 3d of the car room 3c, the car frame 3a and the car 3, the elevator is operated based on the operation instruction of the elevator control panel. Drive on. At this time, the acceleration sensor 11 detects the acceleration of the car floor 3d, detects analog data representing the acceleration, and the sound level meter 21 extracts the noise data during the traveling of the car and sends it to the data collection and recording device 12.

  The data collection / recording apparatus 12 converts analog data representing acceleration detected by the acceleration sensor 11 by the A / D conversion means 12a into digital data and sends the digital data to the data determination means 12b. Also, analog data proportional to the noise detected by the sound level meter 21 is converted into digital data by the A / D conversion means 12f, and similarly sent to the data determination means 12b.

The data determination unit 12b determines whether the data is in a steady state or an abnormal state by using threshold values individually set for digital data representing acceleration and digital data representing noise, and the determination result is used as the data collection processing unit 12e. Notify

  When receiving the steady state, the data collection processing means 12e sequentially records the digital data sent together with the determination result from the data determination means 12b in the steady data recording areas 12db and 12dd of the data record storage means 12d. When full, the data is overwritten by returning to the first data area to reduce the recording capacity of the data recording / storing means 12d.

  When the data determination unit 12b determines that the digital data has exceeded the threshold value, the data collection processing unit 12e outputs the determination result indicating that either or both of acceleration and noise are abnormal and the digital data. To send. Here, the data collection processing unit 12e takes in the date / time data output from the clock function 12c and records it in the abnormal data time history recording area 12da or 12dc for a predetermined time together with the abnormal digital data from the data determination unit 12b. . At this time, the time history data is created by reading out the data before 1/2 of the predetermined time from the steady data recording area 12db or 12dd and transferring it to the abnormal data time history recording area 12da or 12dc.

  Then, the data collection processing means 12e stops data collection and recording in the abnormal data time history recording area 12da or 12dc when a predetermined time has elapsed after the abnormality determination, and sequentially records only in the steady data recording area 12db or 12dd. To go.

  Therefore, according to the above-described embodiment, in addition to the same effects as the first embodiment, the addition of noise not only helps the investigation of the cause of the abnormality, but also passengers can lift the elevator. This can greatly contribute to the improvement of the environment for comfortable use.

  The sound level meter 21 is detachably attached, so that it can be installed not only in the car 3 but also outside the car 3 to measure hoistway noise and can be used effectively.
