Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for controlling an elevator.

Recently, elevators are often controlled by control signals from electronic computers installed in buildings.

For example, when going to work, the service floor of each elevator car is determined and displayed at the landing. FIG. 1 shows an example of this, in which displays 1B1 and 1B2 are provided above the entrances and exits 1A1 and 1A2 on the first floor of No. 1 and No. 2 cars to display the respective service floors. The figure shows that Unit 1 is in service on the 1st, 4th, and 5th floors (upper floors), and Unit 2 is in service on the 1st to 3rd floors (lower floors). These service floors are commanded from the computer in the building.

However, due to computer malfunctions, breakdowns, etc.
That control signal may change. When the control signal changes, the display on the displays 1B1 and 1B2 also changes. For example, the first car is displayed as the 1st floor and the 3rd to 5th floors, the second car is displayed as the 1st floor and the 2nd floor, etc. If this happens several times, the passengers waiting at the platform will be very confused.

The present invention is intended to improve the above-mentioned problems, and aims to provide an elevator control device that does not affect the operation of the elevator even if a malfunction or failure occurs in the electronic computer in the building.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. In addition, those with "1" at the end of the code are for machine No. 1, those with "2" are for machine No. 2, and those without "1" and "2" are for common use with both machines. show.

In the figure, 1c to 5c are the first floors installed in the car.
5th floor destination button (numbers match floor numbers. Others are the same) 1D to 5D are car position signals that become "H" when the car is on the 1st to 5th floors, 1E to 5E are R
-S flip-flop (hereinafter referred to as memory), 1
F~5F is the output of memory 1F~5F, 1st floor~5F
The car call registration signal 7 on the floor is a control signal that becomes "H" when the car is operated within the control, and 8 is the time period signal that becomes "H" during work hours (for example, 8:30 to 9:00). This signal is emitted from a time signal generating means (not shown). 9 is AND gate, 1
0 is a NOT gate, and 11 is a memory, which functions as a storage control means for controlling registers to be described later. 11a is the output, a pattern signal at the time of work, 12 and 13 are control signals issued from the computer on the building side, 12 is the working floor of Unit 1, the 1st floor,
The first service floor command signal becomes "H" when instructing the service floors of the 4th floor, 5th floor, and Unit 2 to be set to the 1st to 3rd floors (Figure 5), and 13 also indicates the service floor of Unit 1. The second service floor command signal becomes "H" when instructing the 1st and 5th floors, and the service floors of Unit 2 to be set to the 1st to 4th floors (Fig. 6). ”
A register that stores the input signal when it goes to "H" from
15 and 16 are AND gates, 15a and 16a are the outputs of AND gates 15 and 16, respectively, and 15a
16a is the service floor command 1st signal, and 16a is the service floor command 2nd signal.
Signals, 17 and 18 are AND gates, 19 to 21 are
It is an OR gate.

Next, the operation of this embodiment will be explained.

When it is time for work, the time signal 8 becomes "H". If Unit 1 and Unit 2 are both in controlled operation, the controlled signals (7-1) and (7-2) are “H”.
becomes. Now, the output of the NOT gate 10 becomes "L" and the output of the AND gate 9 becomes "H", so the memory 11 is set and the pattern signal 11a becomes "H" at the time of going to work, increasing the transportation capacity at the time of going to work. The operation pattern that provides the service is selected.

Now, the first service floor command from the computer on the building side is being sent.
Assuming that the signal 12 has become "H", when the attendance pattern signal 11a becomes "H", the signal 12 is stored in the register 14 and output,
The output 15a of the AND gate 15 becomes "H".
Now, the output of AND gate 17-1 becomes "H", the output of OR gates 19-1 and 20-1 also becomes "H", memories 2E1 and 3E1 are reset, and Destination button 2c
Even if you press 1 or 3c1, the car call registration will be invalidated. At the same time, the display 1B1 of Unit 1 indicates that 1
It is displayed that the 4th and 5th floors are operational floors. In addition, the destination button 1c for the 1st, 4th and 5th floors
1, 4c1, and 5c1 are valid. For example, if the destination button 5c1 for the 5th floor is pressed, the memory 5E1 is set, the car call signal 5F1 becomes "H", and the car call is registered. When the basket reaches the 5th floor,
The car position signal 5D1 becomes "H" and the memory 5E
1 is reset and the car call registration is canceled.
Although not shown, the car responds to calls at the landings on the 1st, 4th, and 5th floors.

On the other hand, the output of AND gate 17-2 also becomes H.
The outputs of OR gates 19-2 and 20-2 also become "H", memories 4E2 and 5E2 are reset, and 2
Car call registrations for the 4th and 5th floors of the car will be invalidated. At the same time, the display 1B2 of the second car indicates that the first to third floors are in service. The car call registration on the first to third floors is valid, and the car responds to hall calls on the first to third floors.

Next, when the first signal 12 becomes "L" and the second signal 13 becomes "H", the output 16a of the AND gate 16 becomes "H". The following operation is easily understood from the above, so it will be omitted, but Unit 1 is from the 2nd floor.
The car call registration on the 4th floor is invalidated, and the display 1B1
This indicates that the 1st and 5th floors are operational floors. Furthermore, the car call registration on the 5th floor of Car No. 2 is invalidated, and the display 1B2 indicates that the 1st to 4th floors are in service.

Now, when going to work, the pattern signal 11a and the first signal 1
2 is "H", even if a malfunction, failure, etc. occurs in the electronic computer on the building side and the second signal 13 becomes "H", this will not be stored in the register 14. Therefore, the output 15a of the AND gate 15
does not change, and the display on the display devices 1B1 and 1B2 does not change. In other words, it does not confuse passengers waiting at the landing.

In the embodiment, the display device 1B1 installed on the first floor,
Although the display for 1B2 has been described, displays may be provided in exactly the same way on other floors as well. Moreover, it is applicable even when there are three or more cars.

Furthermore, it can also be applied to the following cases.

(a) Determine the service floor for each car when retreating and operate;
When using the service floor as a control signal.

(b) When switching the main floor when going to work, the main floor switching signal is used as the control signal. For example, when switching from the first floor to the basement floor, or from the basement floor to the first floor.

(c) When a specific floor is separated from the service floor and operated during a certain period of time without service, the service floor separation signal is used as a control signal.

(d) When the control signal from the building's computer enters a state that would not normally occur (for example, the control signal changes frequently during a certain time period).

As explained above, in this invention, even if the control signal output from the computer to determine the operation mode of the elevator during a certain time period, that is, the control signal output from the computer changes during the time period, The storage contents of the storage means that have already stored control signals are not changed, and the control signals stored at the beginning of the time period are held as they are. Therefore, even if the electronic computer malfunctions or breaks down during a certain time period, it is possible to prevent the elevator operation from being adversely affected.
