Abstract

(57) [Summary] [Purpose] It was possible to detect the number of waiting passengers in the hall and set the door opening time limit according to the number of waiting customers. [Arrangement] The number of waiting customers in the hall is detected by the number of waiting passengers in the hall PW, the comparator CM performs a comparison calculation, and the door opening time setting device DW determines the opening time of the door according to the output. . [Effect] Since the door opening time can be set according to the number of waiting passengers in the hall, a door closing operation or the like does not occur during getting in the car, and safety and driving efficiency can be improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator door opening time limit control device, and more particularly to an elevator door opening time limit control device suitable for improving service on a floor with a large number of waiting customers.

[0002]

[Prior art]

 As a method of detecting the number of waiting customers in the hall and efficiently moving the elevator depending on the number of waiting customers, for example, as disclosed in Japanese Utility Model Laid-Open No. 56-47859, the number of waiting customers in the hall is detected, When the number of waiting passengers exceeded a predetermined value, multiple elevators were selected and serviced for the hall call.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional technology is effective in a relatively large-scale building in which multiple elevators are installed, but the scale of the building is small, and operation in a building composed of one elevator is not considered. However, there was a problem that the same driving was performed on the floors with many waiting passengers and those with few waiting passengers.

An object of the present invention is to remedy the above-mentioned drawbacks, and to provide an elevator door opening time limit control device capable of operating while distinguishing between operations on floors with a large number of waiting passengers and floors with a small number of customers. Especially.

[0005]

[Means for Solving the Problems]

 The purpose of the above is to detect the number of waiting passengers in a hall in a door opening time limit control device for elevators that serve multiple floors, and to open the doors on the floor to be serviced according to the output from this detecting means. This can be achieved by providing a variable means for changing the time limit.

[0006]

[Action]

 The detection means for detecting the number of waiting customers in the hall outputs an output to a variable means according to the situation of the number of waiting customers in the hall, and the varying means changes the door opening time based on the output. That is, when there are many waiting customers, the door opening time limit is set longer, and when there are few waiting customers, it is shortened.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the block diagram of FIG. 1 and the circuit diagram of FIG.

The entire flow will be described with reference to FIG. In FIG. 1, PW is a waiting number detecting device for detecting the number of waiting customers in the hall, and outputs an output according to the number of waiting customers in the hall. The GW is a predetermined waiting customer setting device, which constantly outputs an output serving as a reference for the number of waiting customers. The CM is a comparator, which compares and operates by inputting the number of waiting passengers detection device PW and the predetermined waiting customer setting device GW, and outputs a large output when the number of waiting customers is large and a small output when the number of waiting customers is small. DW is a door opening time limit setting device, and selects the door opening time limit according to the magnitude of the input from the comparator CM.

Next, the operation will be described. As an example, we will explain the case where there are many waiters in the hall and the door open time is extended. Since there are many waiting customers in the hall, the output of the waiting passenger number detecting device PW is large, and the predetermined waiting customer setting device GW outputs the reference output. The comparator CM inputs the signal of the waiting passenger number detecting device PW and the signal of the predetermined waiting passenger setting device GW, and judges that there are many waiting passengers in the hall because the input of the waiting passenger number detecting device is large. Provides a large output signal. The output signal is input to the door opening time limit setting device DW, and since the signal is large, the door opening time limit setting device DW operates to lengthen the door opening time limit.

FIG. 2 shows a circuit diagram of an actual elevator.

In the figure, P and N are DC power supply terminals. S1, S2, and S3 are output signals from the comparator CM. S1 is 0 to 30% of the number of passengers waiting for the passenger in the car, S2 is 30 to 60%, and S3 is 60% or more. Is output to. DW1 to DW3 are timers, and their set values are 3 seconds, 5 seconds, and 7 seconds, respectively. DW1a to DW3a are normally open contacts of DW1 to DW3, and DT is a contactor for instructing door closing, and when activated, gives a door closing start signal to the door control circuit.

The description will be made assuming that the conditions are the same as those described above. Due to the large number of passengers waiting in the hall (over 60% of the number of passengers in the car), S3 is closed. The circuit of P-S3-DW3-N is formed by closing S3, and the timer DW3 starts counting. The timer DW3 is of a timed operation type, and the timer DW3 is energized when the set value of 7 seconds elapses after the circuit is formed. DW3a is closed by the activation of the timer DW3. When the DW3a is closed, a circuit of P-DW3a-DT-N is formed and the door close command contactor DT is energized. The door control circuit is activated by the urging of the door close command contactor DT to close the elevator door.

Hereinafter, when the number of waiting customers is up to 30%, the door opening time limit is 3 seconds, and when it is 30% to 60%, it is 5 seconds.

As described above, according to this embodiment, since the door opening time limit can be set according to the number of waiting customers in the hall, it is safe to board the car when the number of waiting customers is large. In addition, efficient driving is possible.

[0015]

[Effect of device]

 As described above, according to the present invention, the opening time of the door can be adjusted according to the number of customers waiting in the hall, so that the safety is improved and the operation efficiency is improved.
