However, in order to detect passengers in the car, it is not always necessary to detect the load of the passengers. For example, the number of passengers in the car is detected by a pressure sensor, or image data of a camera provided in the car is analyzed by image analysis. It may be detected.

The elevator door sensor 6 is a sensor provided in the car door 15 and may be, for example, an infrared sensor, a photoelectric sensor, a temperature sensor, an ultrasonic sensor, or the like. Further, the elevator door sensor detection means 7 detects the interruption of the sensor by the elevator door sensor 6.

In the car 23, when a passenger who is scheduled to board is detected within the imaging range of the hall camera 1 as the imaging means provided near the hall 27 according to the determination result of the boarding passenger determination unit 17, In-car reporting means 9 is provided for issuing an announcement indicating the presence of a passenger scheduled to board the passenger. In order to alleviate the frustration and discomfort of passengers in the car as an announcement indicating the presence of passengers scheduled to board, for example, an announcement such as “We are driving in energy saving. Alerted to passengers. The landing state detection means 2 connected to the landing camera 1 detects any object, and the detection signal is transmitted from the landing state detection means 2 to the scheduled passenger determination means 17 to detect the scheduled passenger determination means 17. Judgment passengers are determined from the detected objects.

In addition, in the landing 27, when a passenger who is scheduled to board is detected based on the determination result of the boarding passenger determination means 17 based on the image of the hall camera 1 provided at the hall, the passenger who is going to use the elevator is notified. On the other hand, there is provided hall reporting means 11 for issuing an announcement that accurately indicates the operating status of the elevator. As an announcement that accurately indicates the operation status of the elevator, in order to prompt a quick ride, for example, an announcement such as “Elevator is running.

In FIG. 3, an elevator control panel 26 that controls equipment provided at a landing and equipment provided in each car is installed on the side wall of an elevator machine room or hoistway of a building (not shown). The control panel 26 is a door opening control means 16 for controlling the door opening, a boarding passenger determination means 17 for determining whether or not there are passengers scheduled to board the car, and a usage state setting data storage for storing usage state setting data Means 19; utilization state setting data changing means 20 for changing utilization state setting data; utilization state setting data receiving means 21 for receiving utilization state setting data input from an administrator; boarding detection means 8 for detecting boarding of a car; In-car reporting control means 10 for controlling the in-car reporting means 9, landing reporting control means 12 for controlling the landing reporting means 11, and when there is a passenger in the car that is stopped and opened, Carpooling waiting determination means 18 for determining whether or not to wait for a passenger who is going on board, energy saving effective car load determination means 25 for determining the maximum car load effective for energy saving, car traveling means 1 It consists or car position detecting means 24 for detecting the position of the squirrel running control means 14 and the car to control the hoist is.

The usage state setting data receiving means 21 receives the usage state setting data shown in FIG. 2, for example, which is changed by an administrator input from the usage state setting data input means 22 provided in the management room. Examples of the utilization state setting data input means 22 include a PC, a mobile phone, and a pager.

  The usage state setting data changing unit 20 changes the usage state setting data shown in FIG. 2 stored in the usage state setting data storage unit 19 to the data received by the usage state setting data receiving unit 21.

2 and 3, the usage state setting data stored in the usage state setting data storage means 19 are ON / OFF of the energy saving ride mode (1), the maximum value (2) (sec) of the ride waiting time, It includes ON / OFF data of scheduled passenger waiting time (3) (sec) and door closing button priority (4), and is set by the administrator.

In the energy-saving carpool operation mode (1), when a passenger is on the car 23 stopped at the landing 27 and the door 15 is open, and a passenger coming to the elevator is detected, This is a mode to carry out shared driving so that a plurality of passengers can ride in the car at once for the purpose of energy saving.

The maximum value (2) of the carpooling waiting time indicates the maximum waiting time (for example, 60 seconds) during which the carpooling operation can be performed so that passengers in the car do not feel uncomfortable. This value can be determined as follows according to the installation location of the elevator. For example, when an elevator is installed in a department store, it can be set shorter than usual in consideration of the fact that there are many passengers who use the elevator but they come sparsely.

  The scheduled passenger waiting time (3) refers to a time (for example, 10 seconds) that is set so that a passenger scheduled to board can get in the car. This value can be determined as follows according to the installation location of the elevator. For example, when the elevator is installed in a nursing home, the time is set longer than usual in consideration of the walking speed of the elderly. On the other hand, efficient driving is required in places such as offices where people go in and out, so the waiting time for passengers to ride can be set short.

  The carpool standby determination means 18 configured in the elevator control panel 26 includes the contents of the usage state setting data stored in the usage state setting data storage means 19 and the determination of the scheduled passengers determined by the scheduled passenger determination means 17.

The carpooling standby determination means 18 can also use the detection result of whether or not the door closing button is pressed in the car by the door closing button detection means 4 when determining whether or not to place the car 23 on standby. . In this case, when the door closing button detecting means 4 detects that the door closing button has been pushed in the car, the waiting state of the car 23 is canceled and the car is caused to run.

  The boarding scheduled passenger determination unit 17 determines whether or not there is a passenger scheduled to board among the objects detected by the boarding state detection unit 2 connected to the boarding camera 1. For example, the movement of a person is continuously monitored by the landing camera 1, the moving speed is detected based on the position and moving time of the passenger, and passengers exceeding a predetermined speed are considered to have some purpose regardless of the moving direction. It may be considered a scheduled passenger. Further, if the direction of the body and the direction of movement are in the direction of the elevator car, it can be determined that the passenger's line of sight is in the direction of the car regardless of the moving speed and can be regarded as a passenger scheduled to board.

  The boarding detection means 8 detects a passenger who gets in the car from the sensor cutoff signal transmitted from the elevator door sensor detection means 7. Then, the boarding detection unit 8 transmits a passenger detection signal to the carpooling standby determination unit 18.

  The in-car notification control means 10 controls the in-car notification means 9 provided in the car. The hall reporting control means 12 controls the reporting of the hall reporting means 11 provided at the hall 27.

  The car traveling control means 14 controls the driving of the car traveling means 13 that is a hoisting machine. The car traveling control means 14 controls the driving of the car 23 based on the signal transmitted from the carpooling waiting determination means.

  When there are a plurality of cars, the energy saving effective car load judging means 25 transmits a plurality of car positions, other car loads (boarding rates), other car positions, etc. transmitted from a group management control device (not shown). From the above information, the amount of power consumption is calculated and the maximum value of the car load that is effective for energy saving of the elevator, that is, the car load that contributes most to the energy saving, and the car load determining means 25 periodically determines the car load. The maximum value is determined. Then, the energy saving effective car load determination means 25 transmits information on the maximum value of the car load effective for energy saving to the carpool standby determination means 18.

  If the load of the car stopped at the landing in step S103 does not exceed the energy-saving effective car load value, the carpool waiting determination means 18 holds the door 15 fully open to the door opening control means 16 in step S104. Give a command and have the passengers in the car wait. That is, a command for extending the door fully open state from the standard door fully open time (for example, 5 seconds) is given. At that time, a notification to that effect is issued by an in-car notification command and a landing notification command.

  In step S <b> 105, the carpool waiting determination means 18 determines whether or not the boarding scheduled passenger determined by the boarding planned passenger determination means 17 has boarded. If the passenger who is scheduled to board the vehicle gets on, the process proceeds to step S108, the standby state of the car is released, the door is closed, and a car travel command is sent to the car travel control means 14. On the other hand, if the boarding of the passenger scheduled to be boarded is not completed, whether or not a predetermined time has elapsed after detecting the passenger scheduled to board is counted by a timer provided in the carpooling waiting determination means 18 (step S106). . In addition, when a boarding plan passenger is newly detected, it counts up again.

  In step S106, when the predetermined time has not elapsed since the passenger scheduled to ride was detected, the process proceeds to step S107, and the carpooling standby determination means 18 determines whether or not the predetermined time has elapsed since the passenger in the car got on board. Judgment is made using a timer. If the answer is no in step S107, the process returns to step S104. If the answer is yes in step S107, the process proceeds to step S108, the waiting state of the car is released, the door is closed, and the car running control unit 14 is instructed to run the car. send.
