  However, in addition to the control related to the movement of the car, it is desired to adjust the door opening time according to the determination result of whether or not there are passengers so that the passengers can get on more smoothly.

  Accordingly, the present invention has been made to solve the above-described problems, and provides an elevator control device that can adjust the door opening time and allow passengers to get on more smoothly.

  The elevator control device according to the present invention includes a determination unit that receives image data in the vicinity of the landing when the door is open, and determines from the image data whether or not a person is present in a preset passenger detection area. A door opening instruction unit that performs control to continue the door opening when it is determined that a person is present in the passenger detection area.

  When the elevator control device of the present invention determines that a person is present in the passenger detection area set in advance from the image data in the vicinity of the landing received in the door open state, it performs control to continue the door open. The passenger can get on smoothly by adjusting the door opening time.

FIG. 1 is a block diagram showing a main part of an elevator system according to an embodiment of the present invention. In FIG. 1, the control device body 1 can control the operation of the car 2 to stop the car 2 at each floor. A door device 3 is provided on the upper portion of the car 2. The door device 3 is connected to the control device body 1 and opens and closes the car door 4a. The landing door 4b opens and closes in conjunction with the opening and closing of the car door 4a.
A plurality of detection device main bodies 5 are connected to the control device main body 1. Each detection device main body 5 is provided on each floor, and is configured to determine whether there is a passenger near the landing based on image data from each camera device 6. Each camera device 6 is provided in the upper part of the hall on each floor. Each detection device body 5 is connected to a display device (display) 7. The display device 7 is provided, for example, in a manager's room, and is configured to display image data of each camera device 6 via each detection device body 5. Hereinafter, the control device body 1 and the detection device body 5 will be described in detail.

  The control device body 1 includes a communication unit 11 such as an input / output interface, a storage unit 12 such as a memory, and a CPU (processing unit) 13 that controls these operations. The CPU 13 includes a door opening instruction unit 13a that performs control to continue the door opening.

As shown in FIG. 2, the detection device body 5 includes a communication unit 51 such as an input / output interface, a storage unit 52 such as a memory, and a CPU (processing unit) 53 that controls these operations.
In the storage unit 52, passenger detection area data d1, movement detection area data d2, non-detection area data d3, and movement direction data d4 are stored in advance. The passenger detection area data d1, the movement detection area data d2, and the non-detection area data d3 are area data included in the image data from each camera device 6, and are indicated by coordinate data, for example.

The passenger detection area data d1 is data indicating an area set in the vicinity of the hall entrance / exit among the image data near the hall. The moving person detection area data d2 is data indicating an area set at a position farther from the landing entrance than the area indicated by the passenger detection area data d1.
The non-detection area data d3 is data indicating an area from which a process for determining whether or not a person exists is excluded. The non-detection area data d3 is for preventing objects such as a three-sided frame, a guide board, and a potted plant from being mistakenly detected as a person. Therefore, when these objects are not installed near the landing, the non-detection area data d3 may not be set.
The movement direction data d4 is data indicating the direction of the landing entrance from an arbitrary position in the movement detection area indicated in the movement detection area data d2.

  Note that the data d1 to d4 described above are set for each floor by adjusting the shape of each region, for example, in consideration of the shape of the hall, the number of waiting passengers, and the like.

Here, the example of arrangement | positioning of the detection apparatus main body 5 and the camera apparatus 6 installed in the predetermined floor is shown in FIG. According to FIG. 3, the detection device main body 5 and the camera device 6 are provided in the upper part of the hall. A camera device 6 is connected to the detection device body 5.
The image data in the vicinity of the hall imaged by the camera device 6 includes two types of area data, passenger detection area data d1 and moving person detection area data d2. Here, passenger detection area data d1 is set in an area where a waiting customer waits for the car 2 (within a predetermined range in front of the landing door 4b). Further, the moving person detection area data d2 is set in an area further away from the area. The moving person detection area data d2 includes passengers and passersby.

  Next, FIG. 4 shows an example of three types of area data d1 to d3 set near the landing on the predetermined floor. According to FIG. 4, non-detection area data d3 is set on one side of the hall entrance / exit in addition to the passenger detection area data d1 and the movement detection area data d2 in the vicinity of the car and the hall in front of the doors 4a and 4b. Yes. The non-detection area data d3 is set in the non-detection area data d3 because, for example, objects such as a three-sided frame, a guide board, and a potted plant may be installed. However, the non-detection area data d3 may not be set if there is no guide board or the like.

FIG. 5 is a flowchart showing the operation of the detection apparatus main body 5.
When the car 2 arrives and the car and the landing doors 4a and 4b are fully opened, the camera device 6 provided at the landing on the arrival floor takes a picture of the vicinity of the landing. Then, the determination unit 53a of the detection device body 5 receives image data in the vicinity of the landing taken by the camera device 6 (S101).

  Next, the determination unit 53a refers to the storage unit 52 to determine whether there is a person in the passenger detection area data d1 and the movement detection area data d2 among the area data d1 to d3 included in the image data. (S102). Note that whether or not a person exists is determined by pattern recognition, for example.

Then, in the determination by the determination unit 53a (S102), when it is determined that the user is unattended, the determination unit 53a ends the predetermined process.
On the other hand, in the determination in the determination unit 53a (S102), when it is determined that there is a person, the determination unit 53a determines whether the area data in which the person exists is passenger detection area data d1 (S103).

  In the determination by the determination unit 53a (S103), when it is determined that the area data is the passenger detection area data d1, the determination unit 53a outputs a detection signal indicating that the passenger has been detected to the control device body 1. (S104).

  Then, the door opening instruction | indication part 13a of the control apparatus main body 1 performs control which continues the opening operation of the cage door 4a, and the door apparatus 3 continues the opening operation of the cage door 4a. Thereby, the door 4b of the landing will continue to open in conjunction with the door 4a of the car, and passengers can get on more smoothly. The door opening instruction unit 13a outputs, for example, a door inversion command signal to the door device 3 when performing control to continue the opening operation of the car door 4a.

  In the determination by the determination unit 53a (S103), when it is determined that there is a person in the mover area data d2, the determination unit 53a refers to the storage unit 52 and displays the area indicated in the mover area data d2 It is determined whether or not the person is moving in the direction indicated by the movement direction data d4 (S105).

When the determination unit 53a determines that the person is not moving in the direction indicated by the movement direction data d4, the determination unit 53a ends the predetermined process.
On the other hand, in the determination of the determination unit 53a (S105), if it is determined that a person is moving in the direction indicated by the movement direction data d4, the determination unit 53a controls a detection signal indicating that a passenger has been detected. The data is output to the apparatus main body 1 (S104).

  Then, the control for continuing the opening operation of the car door 4a is performed by the door opening instruction unit 13a of the control device main body 1, and the open state of the car door 4a and the landing door 4b is maintained. Thereby, for example, a passenger at a position slightly away from the landing entrance can approach the landing door 4b and get on smoothly.

  Thus, according to the elevator control device of the embodiment, the door opening instruction unit 13a of the control device main body 1 uses the determination unit 53a of the detection device main body 5 to convert the image data in the vicinity of the landing received when the door is open. When it is determined that a passenger is present in the included passenger detection area data d1, control is performed to continue the opening operation of the car door 4a. Therefore, the landing door 4b is also opened in conjunction with the opening operation of the car door 4a, and passengers in the vicinity of the landing doorway can smoothly get on. In addition, when the passenger gets on smoothly, for example, the door opening and closing operations are not repeated many times, and the door can be completely closed by a single door closing operation. Therefore, the operation efficiency of the elevator is increased.

Further, the door opening instruction unit 13a determines in the determination unit 53a that a person existing in the movement detection area data d2 included in the image data is moving in the direction indicated by the movement direction data d4. In this case, control is performed to continue the opening operation of the car door 4a.
For this reason, when a person away from the landing doorway gets on the car 2, the door open state is continued. When a passerby crosses the hall, the door open state is not continued and It will be closed.
Therefore, the door opening and closing operations are performed more smoothly, and the operation efficiency of the elevator is increased.

  Further, the passenger detection area data d1 is set in the vicinity of the hall entrance / exit, and the traveler detection area data d2 is set in an area away from the hall entrance / exit. For this reason, it becomes possible to board the passengers around the hall entrance smoothly.

  Further, since the non-detection area data d3 is included in the image data in the vicinity of the hall, for example, a determination process as to whether or not there is a person is excluded for an installation location such as a three-way frame. Therefore, it becomes possible to speed up detection of passengers.

  In addition, since the determination unit 53a receives image data in the vicinity of the landing on each stop floor, it is possible to detect passengers on the landing on each floor, and the overall driving efficiency of the elevator is increased. Become.

  Furthermore, since the display device 7 is configured to display image data from each camera device 6, for example, an administrator or the like can monitor the situation near the landing. Therefore, each camera device 6 can be used also as a security camera.

  In the above-described embodiment, the determination unit 53a has been described based on the movement direction data d4. The determination unit 53a determines whether the person in the movement detection area data d2 is a passenger. For example, the determination unit 53a may determine whether or not the passenger is a passenger in consideration of preset movement speed data.

  Moreover, although the determination part 53a demonstrated the case where the image data near the landing of each floor was received, you may make it receive the image data near the landing of a specific floor, for example.

  Furthermore, although the case where the detection apparatus body 5 performs distributed processing using a plurality of units has been described, for example, one detection apparatus body 5 may perform batch processing.

  Furthermore, when the detection device body 5 determines that there is no person in the image data, the control device body 1 may perform normal control such as door closing control.

  Further, when the determination unit 53a determines that there is no person in the image data, the detection unit 53a may repeatedly detect passengers based on the latest image data from the camera device 6 within a preset time. Good.

  Furthermore, the passenger detection area data d1, the movement detection area data d2, and the non-detection area data d3 are not limited to those in FIGS. 3 and 4, and may be set freely. For example, the area data d1 to d3 may be set adjacent to each other.
