Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for detecting the number of people getting on and off an elevator.
In particular, the present invention relates to a method of detecting the number of passengers getting on and off using a digital computer.

[Background of the invention]

In recent years, with advances in elevator control methods, it has become possible to control the elevators in a manner that is appropriate to the traffic demand within the building. As an example, it is now possible to extend the opening time of the doors of floors with a large number of users, or to call multiple elevators. Furthermore, when a hall call occurs, traffic demand data is also used to determine which elevator out of several elevators is to be used as the service elevator.

In order to detect this traffic demand, that is, to detect the number of people getting on and off the elevator, there have conventionally been photoelectric devices installed at the entrances and exits, and car self-load detection devices installed under the floor of the car. However, with this device alone, it was impossible to detect and tally the number of people getting on and off the train, even if it was possible to determine whether the number of people getting on or off the train was large or small.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for detecting the number of people getting on and off, which more accurately detects the number of people getting on and off, and enables fine-grained elevator control.

[Summary of the invention]

A feature of the present invention is that the number of people getting on and off the elevator is calculated by inputting the signal from the car load detection device into a digital computer. □ [Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

The present invention will be explained in detail using FIGS. 1 and 2.

In the figure, IF~4F indicates the landing area from the 1st floor to the 4th floor.
HU, 2HD, 2HU, . . . 4HD indicate the hall call buttons on each floor. The rider is a photoelectric device yen + oi

It is equipped with an in-cage load detection device RG. Signals from this device are input to the digital computer MA through a signal line.

Figure 2 (a) is a graph showing the output of the in-car load detection device when a person gets on or off the elevator between the opening and closing of the elevator door.The horizontal axis shows time and the vertical axis shows the output. show. After the door starts,
While people are descending (section a), the load becomes light, so the output decreases.

After that, when a person gets on the vehicle, the load increases and the output increases (section b). Here, the amount of load fluctuation corresponding to the number of people getting off the train is N. (JT, the amount of load fluctuation corresponding to the number of passengers is indicated by NIN. Digital computer MA is
The output of the load detection device is monitored from the time when the door opens to the time when the door is completely closed, and the value RG 1 at the time the door starts opening, the minimum value RG2,
A value RG3 when the door is completely closed is detected. Then, when the door is completely closed, a load variation amount RG 1 - RG 2 corresponding to the number of people getting off the vehicle and a load variation amount RG 3 - RG 2 corresponding to the number of passengers on board are calculated.

Variables in the load inside the car include factors such as movement of people inside the car and shock when the car stops, and load fluctuations can be detected even if no one gets in or out of the car during one door opening/closing operation. be. Therefore, as shown in Figure 2 (b), whether or not a person actually got on or off the vehicle is detected by the operation signal of the photoelectric device, and if there is no operation signal of the photoelectric device, it is assumed that no person got on or off the vehicle. shall be. Next, even if there is an operation signal from the photoelectric device, it is assumed that there are no passengers unless there is a hall call for the elevator-stopping floor. Conversely, even if there is an operating signal from a photoelectric device,
Elevator - If there is no call for the car at the stop floor, it is assumed that there are no passengers getting off the elevator. Using the above algorithm, the previously detected amount of load variation corresponding to the number of people getting off the train and the amount of load variation corresponding to the number of passengers on board are corrected.

FIG. 3 shows the results of counting the detected number of people getting on and off the train for a predetermined period of time by digital computer MA for each floor and driving direction. In this example, it can be seen that there are a large number of passengers on the third floor. The information detected in this way regarding the characteristics of the building, such as the large number of passengers on the third floor, is used when controlling the elevator, and as mentioned earlier, the time limit for opening the door when the third floor is stopped is lengthened, It can be used as an indicator when calling multiple elevators for a hall call on a floor.

〔Effect of the invention〕

According to the present invention, since the number of people getting on and off the train can be detected and totaled using a digital computer, fine-grained elevator control is possible.
