1 is a block diagram illustrating a configuration of a call inspection system according to a first embodiment. It is a figure showing a flow chart concerning processing in a call check system by a 1st embodiment.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) First Embodiment In FIG. 1, reference numeral 1 denotes a call inspection system according to the first embodiment as a whole. The call inspection system 1 includes an elevator car 10, a reporting device 20 for communicating with the outside, and a monitoring center 30 that performs processing related to the call inspection, and the car 10 is connected via the reporting device 20. It is connected to the monitoring center 30. A communication device 11 including a speaker 12, a microphone 13, and an emergency button 14 is installed in the car 10, and the communication device 11 and the monitoring center are connected via a communication device 22 and a control device 23 of a notification device 20. Communication (call) with 30 is performed.

  The notification device 20 is provided on a control panel of an elevator or the like, and communicates with the monitoring center 30 via a communication line 40 via a volume adjuster 21 for adjusting the volume (volume) of the speaker 12 and the microphone 13. A device 22 and a control device 23 for performing various controls are provided. For example, the control device 23 transmits a check report to the monitoring center 30 in response to a call check start instruction from the call device 11 (for example, the emergency button 14 is pressed after switching the check mode as described later). Control. Further, for example, the control device 23 controls the car 10 based on information transmitted from the monitoring center 30 (for example, controls to announce using the speaker 12 as described later).

  The monitoring center 30 includes a control board including a memory (such as a random access memory (RAM) and a read only memory (ROM)) and a controller (such as a central processing unit (CPU) and a microcomputer), a personal computer, and a server device. And so on. The monitoring center 30 includes a communication device 31, a voice recognition device 32, a data collation device 33, and a maintenance database 34, and performs processing related to a call check with the car 10.

  The communication device 31 transmits and receives information to and from the notification device 20 via the communication line 40. For example, the communication device 31 receives voice data of voice input by the maintenance staff (inspector) 50 in the car 10 via the communication device 11. The voice recognition device 32 converts the voice data received by the communication device 31 into text. The data collating device 33 is connected to a communication device 31, a voice recognition device 32, and a maintenance database 34 storing various data for performing elevator maintenance. For example, the data matching device 33 performs comparison and matching between the data converted into text by the voice recognition device 32 and the data stored in the maintenance database 34. The maintenance database 34 stores elevator product information, installation information, customer information, information related to call inspection (keywords, question information, and the like to be described later), and the like. A part of the hardware (function) of the monitoring center 30 may be realized by the controller executing a program stored in the memory.

  In other words, the notification device 20 may be provided on the control panel of the elevator, may be provided on the car 10, or may be provided on another device. Further, the communication device 31, the voice recognition device 32, the data collation device 33, and the maintenance database 34 of the monitoring center 30 are not limited to the configuration provided in one device, but are provided in separate devices. Alternatively, the configuration may be provided separately for some devices.

  FIG. 2 shows a processing procedure of a call check in the call check system 1 of the elevator. In FIG. 2, the process of the communication device 11 and the notification device 20 of the car 10 and the operation of the maintenance person 50 are performed in step X, the communication device 31 of the monitoring center 30, the voice recognition device 32, the data collation device 33, and The processing of the maintenance database 34 is described as step Y.

  The maintenance worker 50 switches the elevator to the inspection mode when starting the call inspection (step X1). Subsequently, the maintenance person 50 presses the emergency button 14 in the car 10 (step X2). As described above, when the emergency mode is switched to the inspection mode and the emergency button 14 is pressed, the notification device 20 transmits (transmits) an inspection notification (inspection notification data) to the monitoring center (step X3). The reason why the inspection mode is set in step X1 is to notify the monitoring center 30 separately from the emergency notification. The inspection report data includes identification information (serial number, unit number, etc.) that can uniquely identify the elevator to be inspected, information on the inspection start time, and the like.

  The communication device 31 in the monitoring center 30 receives the inspection report data (step Y1). The communication device 31 notifies the data verification device 33 of the received inspection report data. Subsequently, the data matching device 33 identifies the elevator as the report source by matching the inspection report data with the installation information in the maintenance database 34 (step Y2). More specifically, the data matching device 33 refers to the installation information including the information of the place (building), the number of the elevator, etc. for each piece of elevator identification information, and Identify if it is an elevator.

  Next, the data matching device 33 extracts the keyword of the elevator to be checked from the maintenance database 34 (step Y3). Here, the keyword is information unique (unique) to the elevator of the reporting source, such as a serial number for identifying the elevator to be inspected and a number for identifying the customer. Except for, the expression method is a constant number.

  The data matching device 33 acquires from the maintenance database 34 a question (announcement data) that causes the maintenance staff 50 in the car 10 to answer the keyword extracted in step Y3, and transmits the question to the notification device 20 via the communication device 31 ( Step Y4).

  Here, in step Y3 and step Y4, when the call check is re-executed as described later, the data collation device 33 may transmit a question requesting the same answer repeatedly a prescribed number of times in the case of a mismatch. Alternatively, different keywords may be re-extracted and questions with different patterns transmitted. Note that the maintenance database 34 holds a plurality of patterns in advance for the keywords and questions in step Y3 and step Y4.

  The communication device 11 of the car 10 causes the question received by the notification device 20 to flow through the speaker 12 into the car 10 (step X4). The maintenance person 50 answers the question from the speaker 12 toward the microphone 13 of the communication device 11 (step X5). The answer voice (voice data) is transmitted to the communication device 31 of the monitoring center 30 via the notification device 20.

  The communication device 31 receives the voice data (step Y5), and notifies the voice recognition device 32 of the received voice data. The voice recognition device 32 performs a process of converting the voice data into text data (step Y6), determines whether or not the text has been converted (step Y7). After the development, the process proceeds to step Y8. If the text cannot be converted, the process proceeds to step Y11. Here, for example, if the voice cannot be converted into text data of a predetermined length during a predetermined period, the voice recognition device 32 may determine that the text cannot be converted. According to this determination, it is possible to eliminate the case where the text data is converted into text data itself, but the read text data is not in Japanese or the like.

  The data matching device 33 compares the text data converted by the speech recognition device 32 with the keyword extracted in step Y3 (step Y8). More specifically, the data matching device 33 determines that the text data converted by the voice recognition device 32 includes an answer list including a plurality of words having different expressions corresponding to the keywords (data stored in the maintenance database 34 in advance). Is included. According to such a configuration, for example, when the answer is “110”, it is possible to determine that all of “Asia”, “Ichizero”, “Ichiichimaru”, “Ichiichirei”, etc. are correct.

  As a result of the comparison, the data matching device 33 determines whether or not there is a match, that is, whether or not the text data includes an answer corresponding to the keyword (step Y9). It is determined that the notification has been made, and an end announcement (announcement data) is transmitted to the notification device 20 (step Y10).

  The communication device 11 of the car 10 sends the end announcement received by the notification device 20 from the speaker 12 into the car 10 (step X6). When grasping the end of the call inspection, the maintenance person 50 releases the elevator inspection mode (ends the inspection) (step X7). When the maintenance person 50 grasps the recheck as described later, not the end of the call check, the maintenance person 50 adjusts the volume of the communication device 11 and then presses the emergency button 14 (step X2) to perform the recheck. Start.

  Here, if the voice data could not be converted to text in step Y6 (NO in step Y7), the data matching device 33 determines that the sound from the car 10 did not have sufficient volume, and An announcement (announcement data) is transmitted to the notification device 20 so as to adjust the volume of the notification (step Y11). The communication device 11 of the car 10 sends an announcement to the car 10 through the speaker 12 to prompt the user to adjust the volume of the microphone 13 received by the notification device 20 (step X6). Subsequently, the data matching device 33 transmits an announcement (announcement data) urging the recheck to be performed to the notification device 20 (step Y12), and ends the process. The communication device 11 of the car 10 causes the announcement, which is received by the notification device 20 and prompts the user to perform the recheck, to flow through the speaker 12 into the car 10 (step X6).

  Further, if the keyword comparison result does not match in step Y9 (NO in step Y9), the data matching device 33 determines that the voice quality from inside the car 10 is poor, and takes measures when the voice quality is poor. Then, an announcement (announcement data) prompting to carry out the recheck is transmitted to the notification device 20 (step Y12), and the process is terminated. The communication device 11 of the car 10 sends an announcement to the car 10 through the speaker 12 to prompt the user to perform a recheck after taking measures against poor voice quality received by the notification device 20 (step X6).

  As a countermeasure when the voice quality is poor, the data collation device 33 prompts the user to confirm the wiring between the communication device 11 and the notification device 20 or prompts the user to perform radio wave measurement when the communication line 40 uses wireless communication. For example, referring to the installation information of the maintenance database 34 (for example, information on which communication line is used by the elevator to be inspected), a countermeasure instruction based on information unique to the elevator is performed.

  As described above, according to the elevator call inspection system 1, the voice answered by the maintenance staff 50 is converted into text data and compared with the keyword, and based on the result, the monitoring center 30 sends the voice from the car 10 to the monitoring center 30. You can check the volume and quality of the audio. In addition, when the result of the call check is abnormal, the maintenance staff 50 has difficulty in determining what measures to take. Since the announcement is made based on the information unique to the elevator, it is possible to efficiently take measures.

(2) Second Embodiment In the call inspection system 1 of the second embodiment, the work of the call inspection is automatically recorded together with the call inspection. In the present embodiment, a configuration different from that of the first embodiment will be mainly described.

  In step Y2 in FIG. 2, the monitoring center 30 according to the present embodiment specifies the maintenance person 50 from the inspection plan of the elevator (acquires the name of the maintenance person 50) in addition to the specification of the elevator of the notification source. The inspection plan may be stored in the maintenance database 34, or may be obtained from a device different from the monitoring center 30. Subsequently, in step Y3, the monitoring center 30 sets the name of the maintenance staff 50 as a keyword. In addition, what is set as a keyword is not limited to the name of the maintenance person 50, and contents unique to the maintenance person 50 such as the employee number of the maintenance person 50 can be adopted. Subsequently, in step Y4, the monitoring center 30 generates a question (announcement data) for causing the maintenance staff 50 in the car 10 to answer the keyword set in step Y3, and transmits the generated question to the notification device 20.

  Then, as in the first embodiment, the data matching device 33 performs the processing of steps Y5 to Y8, and in step Y10, transmits an end announcement (announcement data) to the notifying device 20, and outputs a keyword and a voice. At least one of the data is recorded in the maintenance database 34 as a work result (history). The record of the work results is not limited to the maintenance database 34, but may be a storage device (not shown) of the monitoring center 30 or another device different from the monitoring center 30. There may be.

  As described above, in the present embodiment, by allowing the name of the maintenance person 50 to be answered, it is possible to record the work result of the maintenance person 50. This is a record that the regular maintenance person 50 is reliably performing the call inspection work on the predetermined scheduled inspection date. Also, by recording voice data together, it is possible to present the record even in the event of an accident.

  Further, in the first and second embodiments described above, the case where the keyword is extracted from the maintenance database has been described. However, the present invention is not limited to this, and the keyword is included in the program or is incorporated in the circuit. It may be rare.

  Further, in the first and second embodiments described above, a case has been described in which information specific to the elevator of the reporting source is asked as a keyword, but the present invention is not limited to this, and maintenance personnel are required to provide unique information. A question may be asked using a keyword that can be answered. For example, the keyword may be “2” and the question may be “How many 1 + 1?”.

  In the first and second embodiments, the case where text data is collated with the answer list (correct answer list) has been described. The keyword extracted in Y3 may be searched. In this case, the keyword may include a plurality of words having different expressions. For example, when the keyword is “7”, the data matching device 33 searches the text data to determine which of the words “shichi” and “nana” having different expressions is included.

  In the first and second embodiments, the case where the volume adjuster 21 is provided in the notification device 20 has been described. However, the present invention is not limited to this, and the volume adjuster 21 is provided in the communication device 11. Configuration may be used.
