  The volume data determination unit 42 includes a video acquisition unit 420, an analysis unit 421, and a volume determination unit 422, and determines the usage status of passengers in the car 1. The video acquisition unit 420 acquires the video in the car entrance and the car 1 from the security camera 2 and transmits the acquired video to the analysis unit 421.

  The analysis unit 421 analyzes the video transmitted from the video acquisition unit 420. The analysis unit 421 includes a weak person determination unit 421a and a number of people detection unit 421b.

  The weak person determination unit 421a generates information on whether or not there is a weak person (weak person presence / absence information) from the image of the car entrance acquired by the video acquisition unit 420. As a specific determination method, for example, a method of determining the age group by detecting a face of a passenger boarding the car 1 from a video near the car doorway in the car 1, or a walking cane ( There is a method of determining the weak by determining whether there is a passenger having a white cane for a visually impaired person and whether there is a passenger whose walking speed is slower than a set speed. And the weak person determination part 421a can judge how many weak persons are contained in the passenger in a cage | basket | car from the transition of a passenger's getting-off / boarding condition judged to be a weak person.

  The number-of-people detecting unit 421b generates information (number of people information) about the number of people in the car 1 from the video in the car 1 acquired by the video acquiring unit 420. As a specific detection method, for example, there is a method of judging from color information, motion information, and shape information. The number of people information includes information indicating that the detected number of people is greater than or equal to a preset upper limit number of people (many people information), and information indicating that the detected number of people is less than or equal to a preset lower limit number of people. (Small number of people information) is included. The large number of people information and the small number of people information are generated in order to grasp the congestion situation in the car 1.

  Accordingly, the passenger use status analyzed by the analysis unit 421 is weak person presence information and number information. The weak person presence / absence information and the number of persons information analyzed by the analysis unit 421 are transmitted to the sound volume determination unit 422. The volume determination unit 422 determines an optimal announcement volume to be reported in the car 1 based on the weak person presence information and the number information. The volume determination unit 422 has a basic volume set in advance, and determines whether to increase or decrease the basic volume based on the weak person presence / absence information and the number of persons information. As a specific example of the method for determining the announcement volume, a case where three-stage volume setting is performed will be described below.

  Determination of the first sound volume: The sound volume determination unit 422 is at least one of information indicating that the passengers are vulnerable (weak information) and a large number of people (information in which the car 1 is congested). If two pieces of information are received, it is decided to make an announcement at a volume higher than the basic volume.

  Determination of the second sound volume: When the sound volume determination unit 422 receives both the information indicating that the passenger does not include the weak (no weak information) and the small number of people (information in which the car 1 is vacant) , Decide to make the announcement at a volume lower than the basic volume.

  Determination of the third volume: In cases other than the above two, the volume determination unit 422 determines to make an announcement at the basic volume.

  In the above three-level volume setting, the volume types are limited to three types: a volume larger than the basic volume, a basic volume, or a volume smaller than the basic volume. It is not limited to the stage. For example, the sound volume determination unit 422 stores in advance a plurality of different sound volume tables depending on the number of people in the car and the presence or absence of the weak, and selects a sound volume corresponding to the received information on the presence or absence of the weak and the number of people. You may decide to make an announcement.

  When the volume data determination unit 42 receives a volume setting command from the announcement control unit 40, the volume data information set according to the use situation of passengers in the car 1 is sent to the announcement control unit 40 as described above. Send back. When the announcement control unit 40 receives the audio data information acquired from the audio data storage unit 41 and the volume data information determined by the volume data determination unit 42, the announcement control unit 40 transmits it to the volume adjustment unit 43.

  The volume adjusting unit 43 synthesizes voice based on the voice data information and adjusts the volume based on the volume data information. The sound and the notification information whose volume has been adjusted by the volume adjustment unit 43 are issued from the speaker 30 toward the passenger.

  Next, a series of operations until an announcement is issued to passengers in the car 1 will be described using the flowchart of FIG. FIG. 3 is a flowchart showing a series of operations until an announcement is issued to passengers in the car 1 according to Embodiment 1 of the present invention.

  As shown in FIG. 3, first, the volume data determination unit 42 acquires the video from the security camera 2 via the video acquisition unit 420, and always analyzes the presence / absence information of the weak person and the number of people information by the analysis unit 421. (Situation analysis step, step S101).

  Next, the control panel 5 determines whether or not an announcement is necessary for the passengers according to the operation status of the elevator (step S102). When the control panel 5 determines that an announcement is necessary for the passenger, the control panel 5 extracts the notification information corresponding to the determined driving situation from the notification information storage unit 50 and sends it to the announcement control unit 40 via the control cable 6. The notification command is transmitted (step S103).

  When the announcement control unit 40 receives a notification command from the control panel 5, the announcement control unit 40 acquires voice data information corresponding to the notification information from the voice data stored in advance in the voice data storage unit 41 (step S104). In parallel with step S104, the announcement control unit 40 transmits a volume setting command to the volume data determination unit 42 (step S105).

  The volume data determination unit 42 that has received the volume setting command determines the volume data information based on the weak person presence / absence information and the number of persons information analyzed in step S101 at the timing of receiving the volume setting command ( Volume determination step, step S106). The volume data determination unit 42 returns the determined volume data information to the announcement control unit 40.

  When the announcement control unit 40 acquires the audio data information and receives the volume data information, the announcement control unit 40 sends the audio data information and the volume data information to the volume adjustment unit 43 (steps S107 and S108). The sound volume adjusting unit 43 generates sound based on the received sound data information and the sound volume data information, adjusts the sound volume, and issues the sound from the speaker 30 to the passenger (step S109). The series of operations until the announcement is issued to the passengers in the car 1 is thus completed.

  According to the first embodiment as described above, the announcement device includes the video acquisition unit that acquires the video of the security camera, the weakness presence / absence information and the number information (that is, the passenger's information) analyzed from the video acquired by the video acquisition unit. And a volume determination unit that determines the announcement volume based on the usage status. This security camera is generally provided for monitoring for the purpose of security in a car. By providing such a configuration, it is possible to detect the weak presence / absence information and the number of people information necessary for determining the announcement volume without providing a special device. As a result, an increase in cost due to a separate device for determining the announcement volume can be suppressed.

  In addition, the volume determination unit determines that the announcement is performed with a volume larger than the basic volume when at least one of the vulnerable information and the large number of people information is received. Thereby, it is possible to make it easier for the weak in the car to hear the contents of the announcement. In addition, it is possible to make it easier for passengers who are far from the speaker to hear the contents of the announcement when the car is congested.

  Furthermore, the volume determination unit determines that the announcement is performed at a volume smaller than the basic volume when both the weakly absent information and the small number of people information are received. Accordingly, when only a healthy person is in the car and the number of passengers is small, it is possible to prevent the passenger from feeling uncomfortable due to the large announcement volume. As a result, it is possible to obtain an announcement device that can automatically set an appropriate announcement volume in accordance with the situation in the car.

  Also, the announcement volume is automatically set by the volume determination unit according to the situation in the car, so the conventional announcement volume is set to a constant value, and when you want to adjust the announcement volume, open the in-car operation panel. The trouble of manually adjusting the volume from the announcement device installed inside can be saved.
