The output information generation unit 57 generates output information for notifying the number of passengers calculated by the number of passengers calculating unit 56 and transmits the output information to the in-car broadcasting device 23.

<Operation of Elevator System According to One Embodiment>
Next, the operation of the elevator system 1 according to the present embodiment will be described. In the present embodiment, the hall 3 is photographed by the monitoring camera device 31 while the system is operating, and the generated photographing information is transmitted to the elevator control device 5 via the transmission cable 43. Further, in the load detection device 21, the deflection amount x of the floor surface 22 is measured at a predetermined time interval by a deflection measuring device 211 installed on the floor surface 22 of the car 2, and transmitted to the elevator control device 5 via the transmission cable 41. Has been.

  An operation executed by the elevator control device 5 in a state where these pieces of information are transmitted will be described with reference to the flowchart of FIG.

  In the elevator control device 5, the deflection amount x transmitted from the load amount calculation unit 52 is acquired by the measurement value acquisition unit 51, and the load applied to the car 2 by the load amount calculation unit 52 from the acquired deflection amount x. A quantity is calculated. Further, the shooting information acquisition unit 53 acquires the shooting information transmitted from the monitoring camera device 31.

  When the door opening / closing information acquisition unit 54 acquires door opening information indicating that the car door 24 is opened (S1), the analysis unit 55 analyzes the shooting information acquired by the shooting information acquisition unit 53. Thus, a process of detecting a user waiting for an elevator at the hall 3 is performed. For example, a binarization detection method is used for the process of detecting the user from the photographing information.

  Here, when a user waiting for an elevator is detected at the hall 3 (“YES” in S2), the load amount of the car 2 calculated by the load amount calculation unit 52 in the passenger capacity calculation unit 56 is the car in advance. It is determined whether the rated load capacity set to 2 has been exceeded (S3). As a result of the determination, when it is determined that the load capacity of the car 2 does not exceed the rated load capacity (“YES” in S3), the car 2 is moved to the car 2 based on the load capacity of the car 2. The number N of passengers that can be boarded is calculated (S4). The number of passengers N is calculated by the following equation (1).

[Equation 1]
N = INT {(rated load capacity-current load quantity) / standard weight} (1)
However, INT (I): An integer value not exceeding I. The standard weight is a value preset as the weight of one person, for example, 65 kg.

  If the calculated number of passengers N is 1 or more (“YES” in S5), output information for notifying the calculated number of passengers that can be boarded is generated by the output information generation unit 57 and is transmitted via the transmission cable 42. It is transmitted to the in-car broadcast device 23 (S6). The output information is, for example, voice information “N more people can ride”.

  In the car broadcasting device 23, the output information acquired from the elevator control device 5 is broadcast, and the number of people who can board the car is notified to the users in the car.

  According to the above embodiment, when the car 2 is landing on one of the floors and the door is opened, the number of people that can be boarded is notified, and therefore the car 2 is somewhat congested. The user of the hall 3 hesitating about boarding can be urged to board, and unloading is reduced, so that the elevator can be operated efficiently.

  In the embodiment described above, the monitoring camera device 31 is installed only at the halls 3 on the top floor and the bottom floor of the building, and the number of passengers that can be boarded is notified when the car 2 is opened on these floors. Also good. Thus, by installing the monitoring camera device 31 only in two places, it can be configured at a lower cost than the case where it is installed on all floors. Usually, it is possible to get on the intermediate floor other than the top floor and the bottom floor because it is not possible to determine whether the user of hall 3 is waiting for the elevator for the upper floor or the elevator for the lower floor Although notification of the number of passengers may be useless, the destination direction is determined on the top and bottom floors, so the reported number of passengers can be used effectively, eliminating unnecessary notification processing be able to.

  Further, as shown in FIG. 5, in the hall 3 on the intermediate floor, for each destination direction of the user of the hall, a line 34 a surrounding the first area 33 a set to “upper floor” and “to lower floor” A line 34b surrounding the set second area 33b is shown, and the analysis unit 55 of the elevator control device 5 waits for the elevator in the first area 33a from the shooting information shot by the monitoring camera device 31. You may be made to detect a user and the user who is waiting for an elevator in the 2nd area 33b, respectively. In this way, by detecting the users for each destination direction, only when a user waiting for an elevator in an area corresponding to the current traveling direction of the car 2 is detected, the number of passengers calculating section 56 The number of passengers that can be boarded is calculated and the processing can be performed efficiently.

  Moreover, in embodiment mentioned above, it is comprised so that the output information generation part 57 of the elevator control apparatus 5 may acquire the operation information performed with the operation panel in the passenger car 2, and the output information for alert | reporting the number of people who can board is provided. After the transmission, when the operation information indicating that the door opening button has been operated is acquired from the operation panel, output information for prompting the user in the car 2 to move toward the back is generated. You may make it transmit to the in-car broadcasting apparatus 23. FIG. The output information that prompts the user to move to the back is, for example, voice information for announcing “please pack”.

  By performing the process in this manner, after the number of people who can board the car is announced by an announcement such as “You can ride 2 or 3 more people”, the door in the car 2 is opened so that the users in the car 3 can get on the board. When the button is operated, it is possible to prompt the user who is already in the car 2 to pack in the back so that the user of the hall 3 can easily get on.

  In the above-described embodiment, the hall information 3 is output from the shooting information analyzed by the analyzing unit 55 within a predetermined time after the output information generating unit 57 of the elevator control device 5 transmits the output information for notifying the number of people who can board the vehicle. If it is determined that the user has moved to get on the car 2, even if the door closing button is operated on the operation panel in the car 2, even if the operation is disabled for a predetermined time (for example, 5 seconds) Good.

  By processing in this way, it is possible to make it easier for the user of the hall 3 to get on the car 2 and to drive more efficiently.
