DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for measuring the traffic volume of an elevator, and more particularly to a device for easily and accurately measuring the traffic volume of an elevator.

[0002]

2. Description of the Related Art Conventionally, elevator traffic has been measured to ascertain the use status of elevators and used for elevator management. That is, the traffic volume of the elevator differs depending on the use of the building or facility where the elevator is installed and the characteristics of the user. Therefore, by measuring the traffic volume of the elevator, it is possible to improve the elevator installation plan and the elevator management method, and to provide a functional and comfortable elevator.

[0003] The traffic volume of an elevator refers to the number of passengers on the stop floor of each elevator within a certain time.

However, conventionally, a traffic flow measuring device must be separately installed in the elevator system to perform the measurement, and it has not been possible to easily measure the traffic flow of the elevator.

[0005] The state of measurement of the traffic volume of a conventional elevator will now be described with reference to the drawings. FIG. 8 is a diagram showing a state of measurement of a conventional traffic volume. As shown in FIG. 8, the elevator system 1 includes an elevator car 10, a counterweight 12, and a hoisting motor 14 for driving the elevator car 10 up and down.
It is composed of A hall-side display guide unit 20 is provided on the hall side of the elevator, and a user of the elevator calls the elevator car 10 to the use floor by a call button of the hall-side display guide unit 20. The elevator car 10 includes a weighing device 16 for detecting the load weight of the elevator.
Is installed. The detection result of the weighing device 16 is supplied to the operation control unit 22 via the car-side data transmission device 18. The operation control unit 22 supplies a detection result of the weighing device 16, that is, a current corresponding to the weight to the hoist motor 14 to control the operation of the elevator. Thus, the weighing device 16
It was provided to control elevator operation and was not used to measure elevator traffic.

In such an elevator system 1, when measuring the traffic volume, for example, the operation control unit 2
2, an elevator traffic volume measuring device 40 was separately connected. Therefore, in the traffic volume measuring device 40 as shown in FIG. 8, the period from the installation of the traffic volume measuring device 40 to the removal thereof is defined as the traffic volume measuring period.

[0007] In addition to the above-described traffic flow measuring device, the movement of a user into and out of an elevator car is detected by using a photoelectric cell to detect the movement of a person, and the movement of the person is analyzed so that the traffic of the elevator can be measured. Methods for measuring have also been proposed.

[0008]

In the conventional traffic flow measurement shown in FIG. 8, a traffic flow measuring device must be installed and removed separately from the elevator. Work time was required. In addition, in such a traffic volume measurement, it is impossible to measure the traffic volume during a period in which the traffic volume measuring device is not installed, and therefore, it responds to a sudden request from a manager of a building or facility where an elevator is installed. I couldn't do that.

In the method of measuring the traffic volume using the photoelectric cell, when the traffic volume is large or when the occupant gets on and off the elevator car at the same time, the movement of the occupant is accurately detected and analyzed. Was unable to measure traffic accurately.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to easily and accurately measure the traffic volume of an elevator.

Another object of the present invention is to make it easier to measure the traffic volume of an elevator by enabling the measurement of the traffic volume of an elevator to be controlled remotely.

4 of the I / O interface 24e. When the door open signal is supplied to the I / O interface 24e, RA
M24c stores the change in the load weight detected by the weighing device 16. The change in the load weight of the elevator car 10 is stored while the door is open, and the change is shown in FIG.
It is stored as shown in FIG. Referring to FIG. 3A, the load weight first decreases (a), then the load weight increases (b), and the load weight decreases again (c), and the load weight stabilizes. In relation to the number of passengers, some people first get off the elevator car 10, and then some people get on and off. Further, when the total amount of the load weights in the case of FIG. 3A is obtained, the total amount of the get-off load weights is obtained by (a) + (c), and the total amount of the ride load weights becomes (b) (FIG. C)). The number of getting off persons is calculated by dividing the total amount (a) + (c) of the getting off load weight by the average occupant weight, for example, 65 kg / person. Similarly, the number of occupants also calculates the total amount (b) of the occupant load weight as the average occupant weight 65 kg /
Divide by the person to calculate the traffic volume on this floor.

Referring to FIG. 3B, the total weight of the getting off load is (b), and the total weight of the getting off load is obtained by (a) + (c) (see FIG. 3C). Similarly, the number of passengers getting on and off is calculated from the total amount of these load weights, and the traffic volume is calculated.

In the calculation of the load weight, it is preferable to store the maximum load weight up to 110% of the car maximum capacity. This is because the load weight exceeding 110% is considered to be a temporary load weight, for example, when the driver temporarily gets on board beyond the capacity, and does not affect the calculation of the traffic volume.

The measurement of the traffic volume is performed as described above. In the measurement processing, if there is a setting such as a measurement start date and time and a measurement end date and time, the measurement is performed for the period and the RAM of the traffic volume measurement device 24 is measured.
24c stores the measurement result. If the measurement start date and time and the measurement end date and time are not set, the RA of the traffic
The measurement results are stored and accumulated within the storage capacity of M24c. Alternatively, the data may be updated when the storage capacity is exceeded.

The RAM 24c stores the measurement result of the traffic volume of each floor, the running floor of the elevator, the running direction, the measuring time, the driving mode, and the like.

The measurement result can be output by the operation device 26 or any output device. FIG. 4 shows an output example of the measurement result. The measurement result can be output as shown in FIG. 4, and it is also possible to output only a predetermined floor for each time.
