Description

[Detailed Description of the Invention] This invention relates to an improvement of an elevator notification device.

In recent years, there has been a strong demand not only for more efficient elevator operation, but also for improved quality of service to passengers. In response to this, there has recently been a strong desire to improve communication between elevators and passengers, such as displaying service carts in front of the elevators to guide passengers, and to improve psychological services for passengers (alleviating feelings of irritation, etc.). ing.

2. Description of the Related Art Conventionally, elevators are equipped with various operations in order to operate safely or to prevent elevator service from being degraded. For example, if it is detected that there are too many passengers in an elevator car (more than 110% of the normal car capacity), a buzzer or other alarm will sound to warn the passengers that the car is overcrowded, and the car will be held until the overcrowding is resolved. There is a safety operation that prevents the vehicle from departing (hereinafter referred to as the operation to cut off operation when overboarding). In addition, if it detects that a passenger is touching the door safety device installed on the front edge of the door and the door remains open for a predetermined period of time, resulting in a delay in service to other calls, an alarm will be activated. There is also a forced door closing operation that alerts passengers by sounding the door and forcibly starts the door closing operation. Sounding an alarm when issuing such a warning is a common practice in the event of abnormal conditions.

However, some passengers do not know what the alarm is warning them about, and as a result, the alarm's warning can end up causing disasters, such as delaying the departure of the car and deteriorating the service for other calls. can also be considered. In addition, even though only the forced door closing operation is working, some passengers get off the train in a hurry, mistaking it for a warning that they have overboarded, and miss getting on, so it can be said that this is an unkind warning for passengers.

This invention is intended to improve the above-mentioned problems, and aims to provide an elevator notification device that allows passengers to understand the meaning of the warning when the warning device is activated.

An embodiment of this invention will be described below with reference to figures.

In the figure, 1 is an overload signal that becomes "H" when the load in the car exceeds the predetermined value, 2 is a fixed time signal corresponding to a fixed time (for example, 5 seconds), and 3 is a buzzer or bell installed in the car. 4 is a display judgment device, 5 is a time counter that counts the elapsed time while the input signal at point I becomes "H", and when the input signal at point R becomes "L", the contents is reset to zero. 6 is NOT gate, 7 is input signal of X point>Y
A comparator 8 is provided in the car, and when the input signal changes from "L" to "H", the output signal becomes "H" and "L" otherwise. This is a well-known annunciator consisting of a device that performs composite broadcasting, and is constructed at a lower cost than a conventional broadcasting device that uses recording tape.

Next, the operation of this embodiment will be explained.

The car is currently on the floor, and when more than 110% of its capacity is filled with passengers, the overboard signal 1 becomes "H," the above-mentioned overboard operation cut-off operation is activated, and the car is unable to depart. At the same time, the alarm 3 sounds and the time counter 5 counts this elapsed time. if. Even if the alarm 3 starts sounding, if 5 seconds pass without the passenger noticing that the passenger has overboarded, the output signal of the comparator 7 becomes "H". The alarm 8 then broadcasts, for example, "You are riding too much. If you are the last one, please get off." Such audio broadcasts help to foster human communication with passengers and alleviate their discomfort. As a result of this broadcast, when some passengers get off the car and the number of passengers in the car becomes less than 110% of its capacity, the overboard signal 1 becomes "L" and the alarm 3 stops sounding. In addition, the output signal of NOT gate 6 becomes "H",
Since the content of the time counter 5 is reset to zero seconds, the output signal of the comparator 7 becomes "L". The broadcast of the alarm 8 is now stopped. On the other hand, the operation of disconnecting the car when the car is overloaded is canceled, and the car starts closing its door for departure.

In this way, if the operation of issuing a warning to the passenger continues or is intermittent for a predetermined period of time or more, the passenger does not yet understand the meaning of the warning, and the guidance information is given in a way that helps the passenger understand the meaning. This allows the car to quickly return to normal operation and prevent service for other calls from deteriorating.

It is also possible to implement as follows.

(a) Applies when a forced door closing operation is provided.

(b) As the alarm 8, use one that provides visual notification such as text display.

As mentioned above, this device generates a non-verbal warning once a driving impediment is detected, prompting indirect action to be taken, and if it remains detected after a predetermined period of time, the passenger It is determined that the response action is not known, and the cause is specifically identified and notified to the passenger using letters or verbal sounds. Through this notification, the passenger who caused the obstruction to driving becomes clear, and the presence of a passenger who deliberately pretends not to understand is not tolerated.

Therefore, a corresponding action can be taken quickly, and normal operation can be returned to normal operation quickly.

In addition, the method of issuing an indirect warning at first and then specifying the specific content is more interesting than the method of repeating the same warning or increasing the volume.
It also has the effect of being more in tune with human emotions.
