Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for displaying information inside an elevator car.

When a power outage occurs in a building, an emergency generator is typically started and the power is supplied to the minimum necessary equipment within the building.

When multiple elevators are installed in a building, the electricity required to operate one elevator is usually supplied, so the cars can be operated one by one and rescued one by one. There is.

However, before you can be rescued, you have to wait for your turn, and during that time no information is given to you inside the cage. As a result, they have no choice but to wait anxiously, not knowing what's going on with the elevator or how long they should wait before being rescued. If power outages and electric earthquakes or fires occur simultaneously, this anxiety will deepen at any moment.

This invention is intended to improve the above-mentioned problems, and aims to provide an in-car display device for an elevator that does not cause anxiety to passengers in the car during a power outage and allows them to wait for rescue.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In addition, those with A to C at the end of the code indicate those for machines No. 1 to No. 3, respectively.

It is a gate.

Next, the operation of this embodiment will be explained.

Now, when a power outage occurs in the building, the power outage signal 3 becomes "H". It is also assumed that emergency power supply has been established. The rescue order of the cars is Unit 1, Unit 2, Unit 3.
In order of machine number.

Car position signal 8A of car No. 1 and floor signal 9 of the 1st floor
1A, the mileage calculation circuit 10 calculates the distance that the first car should travel, and the decoder 11 converts it into the required time. At this time, since the earthquake signal 19 and the failure signal 4A are "L",
The output of the AND gate 20 is "H".
On the other hand, since the output of AND gate 21 is "L", gate 16 is closed. Further, the gate 18 is also closed. Therefore, the decoder 11
Only the contents of the rescue time signal 1 are transmitted through gate 12.
Emitted as aA. Now, the rescue time display 6A of the first car displays the time until the first car reaches the first floor inside the car, giving passengers a sense of security. Unit 1 now travels to the first floor, and the rescue is completed here. Similarly, the arithmetic circuit 1B calculates the rescue time of the second car, and the adder 2B adds it to the rescue time of the first car, and this is displayed in the car of the second car by the display 6B. This is because the rescue of Unit 2 is started only after the rescue of Unit 1 has been completed. Similarly, the rescue time of the No. 3 car is calculated by the arithmetic circuit 1C, and added to the rescue time of the No. 2 car by the adder 2C, and displayed on the display 6C of the No. 3 car. The times displayed on these displays 6A to 6C reflect the calculation results of the calculation circuits 1A to 1C, and change over time to display the latest information. During this time, if machine A fails, failure signal 4A becomes "H" and AND
The output of the gate 20 becomes "L", the gate 12 is closed, and the rescue time signal 1aA is no longer generated. On the other hand, if the failure signal 4A becomes "H", the OR
The output of the gate 5A becomes "H" and the indicator 6A goes out. Instead, the failure indicator 7A lights up to indicate the failure. Furthermore, since the gate 18 is opened, a zero signal is issued through the gate 18, and the rescue time signal 1aA of the first car has a value corresponding to zero. Therefore, the rescue time for Units 2 and below will be shortened accordingly.

If an earthquake occurs during a power outage, the earthquake signal 1
9 becomes "H", the output of AND gate 20 becomes "L", and gate 12 is closed. On the other hand, if there is no failure, the output of the AND gate 21 becomes "H" and the gate 16 is opened. In the floor selection circuit 13, the car position signal 8A and the floor signal 9
The nearest floor is selected from 1A to 99A, and the distance therebetween is calculated from this and the car position signal 8A. The decoder 15 converts the above-mentioned distance into the time required to travel at a constant low speed (20 to 30 m/min) (at the time of an earthquake, the vehicle is driven at low speed in consideration of safety). Therefore,
The contents of the decoder 15 are issued through the gate 16 as the rescue time signal 1aA. Display 6A-6
The display by C, switching to the indicators 7A to 7C in the event of a failure, etc. are as described above.

Note that even if a fire occurs during a power outage, the display will remain the same as above. This is because even in the case of a fire, the rescue floor is the first floor.

Note that the following can also be implemented.

(a) Display the time until rescue of your car starts.

(b) Display the rescue time by changing the flashing frequency, brightness, color, lighting area, etc. of the display.

(C) The position indicator inside the car and the car call registration light with a built-in destination indicator light are shared, and the display format is changed to display the rescue time.

(d) Broadcast the rescue time via audio.

(E) Rather than displaying the rescue time from time to time, e.g.
The display changes step by step at approximately 20 second intervals.

(F) Instead of displaying the time as "XX seconds," display text such as "Please wait for a while" or "We will rescue you soon."

(g) Calculation of rescue time shall be performed in detail for each position of several millimeters, or roughly for each floor.

(h) In the case of (e) and (f), no special calculation is required,
The display changes after a certain period of time has elapsed.

FIGS. 3 and 4 show another embodiment of the present invention, in which the rescue status of each car is displayed within each car.

In the figure, 25 is a rescue situation detection circuit, 26 is a running signal that becomes "H" while the car is running, 27 is a door open signal that becomes "H" when the car door is opened, and 28 is a car 1
Car position signal that becomes "H" when on the floor, 29~
32 is AND gate, 33 is OR gate, 34 is
NOT gate, 35 is a memory, 33 is a rescue status indicator installed in the car, 34 is a rescue indicator that displays, for example, "Unit 0 is being rescued" when lit, 3
Reference numeral 5 is a rescue completion indicator that similarly displays "Rescue of Unit 0 has been completed," and reference numeral 36 is a power outage indicator that also displays "Power outage. Please wait for a while." Incidentally, exactly the same type is used for the second and third machines.

When the power outage signal 3 becomes “H”, the power outage indicator 36
A lights up (I will explain about the first machine, but it is the same for all machines). If Unit 1 runs, running signal 2 will be activated.
6A becomes "H", the output of AND gate 31A becomes "H", and the rescue indicator 34A lights up.
It is displayed that the No. 1 car is currently in rescue operation in each car. When the first car reaches the first floor and the door opens, the car position signal 28A and door open signal 27A are activated.
becomes "H", the output of AND gate 30A becomes "H", the output of OR gate 33A also becomes "H", memory 35A is set, and its output becomes "H". Now AND gate 32
The output of A becomes "H" and the rescue completion indicator 35A
lights up to indicate that the rescue of Unit 1 has been completed. Meanwhile, due to the stoppage of Unit 1, the running signal was 26.
Since A becomes "L", the output of the AND gate 31A becomes "L", and the rescue indicator 34A turns off.

Next, when Unit 2 runs, the rescue indicator 34B
lights up, and when the first floor is reached and the door is opened, the rescue completion indicator 35B lights up. Below, Unit 3 will be displayed in the same way.

If an earthquake occurs, when the car stops at the nearest floor and the door opens, the door open signal becomes "H" and the output of the AND gate 29A becomes "H", so the rescue completion indicator 35A lights up.

In addition, when the power outage is restored and the power outage signal 3 becomes "L", the power outage indicator 36A and the rescue indicator 34A
goes out. On the other hand, since the output of NOT gate 34A becomes "H", memory 35A is reset and its output becomes "L". Therefore,
The output of the AND gate 32A becomes "L" and the rescue completion indicator light 35A also goes out.

Note that the following can also be implemented.

(k) Only display other baskets.

(j) Display the car position of other cars as an indication of rescue status. A television receiver is installed inside the car to display the surroundings of the staff management panel.

(S) Broadcast the rescue situation via audio.

As explained above, in this invention, the time required to rescue each car during a power outage is calculated and the rescue time of that car is displayed in each car, or the rescue status of each car is detected and this is displayed in each car. Since the display is displayed on the screen, passengers in the car can wait for rescue with peace of mind during a power outage without worrying about it.
