Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a notification device installed in an elevator hall.

Normally, an elevator registers a hall call using an up button or a down button installed at the hall, and uses this hall call to summon a car. Then, a passenger who has boarded the arriving car registers a car call using a destination button installed inside the car, and drives the car to a desired floor. In this way, in conventional elevators, it is necessary to operate call buttons at the landing and in the car.

Recently, for example, as shown in Japanese Utility Model Publication No. 53-40843, it has been proposed to provide a common destination button for each car at the landing, similar to the one inside the car, and to provide a destination floor indicator for each car at the landing. There is. When a waiting passenger registers a destination floor call by operating a landing button, the most suitable car is assigned to each destination call, and the destination floor display shows the assigned destination call. The floor is displayed, and the waiting customer who operates the hall destination button is informed of the assigned car, and the destination floor of each car is also displayed to other waiting customers. In this case, as soon as a destination call is assigned, it is automatically registered as a car call for the assigned car, which saves waiting customers the trouble of operating destination buttons in the car. Also,
This is very convenient as it eliminates the possibility of being unable to operate the destination button in the car due to congestion in the car. Furthermore, as shown in Japanese Patent Application Laid-Open No. 55-80659, when an assigned car arrives at the floor where the landing button has been operated, the car call for the floor corresponding to the destination call can be automatically registered. Proposed.

However, the above-mentioned destination floor display is too expensive to provide for each floor and each car, which poses a practical problem.

Therefore, instead of installing destination floor indicators at the boarding area, we decided to use up and down hall lanterns (hereinafter referred to as HL).
It is also being considered to install only one car, divide the registered destination calls into up and down directions, register them as up and down calls, and allocate one car to each. Then, in the same way as when conventional up and down buttons are installed, by lighting up the HL of the assigned car, the service car forecast will be announced to waiting customers. are registered as car calls all at once. In this case, a car is not assigned to each destination call, so a destination floor indicator is not necessary.
By lighting the HL, it is possible to inform the waiting passenger of the car in which he or she should ride, that is, the car in which the car call of the desired floor of the waiting passenger is automatically registered, before the waiting passenger arrives.

However, before the assigned car is decided to stop at the landing, the HL is normally lit and used as a forecast guide display for the service car, and also when the car is used for landing calls (up calls, down calls, and destination calls) and car calls. When the car is determined to stop in response, it is used as an arrival guide display to notify the arrival of the car and the direction of travel by flashing it, regardless of whether it is an allocated car or a non-allocated car. Therefore, when two or more cars including the assigned car have arrived, passengers cannot be guided preferentially to the assigned car (therefore, the car in which the car call is automatically registered). In other words, a passenger who arrived at the landing late and operated the landing destination button,
Since the arrival forecast lights of all the cars have the same arrival information display, it is difficult to tell which car will automatically register the car call based on the destination button you operated. As a result, a passenger riding in a car that is not the assigned car (therefore, a car whose car call is not automatically registered) must take the trouble of pressing the destination button again in the car. Further, car calls are registered in the assigned car unnecessarily, reducing the efficiency of elevator operation.

In addition, if a waiting passenger operates a landing destination button when there are two or more cars that have arrived in response to a car call at a landing without a hall call, the passenger can choose which car (in this case, the elevator In consideration of operational efficiency, the number of cars for which car calls are automatically registered is normally limited to one car), so the above-mentioned problem occurs because it is not possible to tell which car should be boarded.

Further, in an elevator where only an up button and a down button are provided at the landing, it may be possible to predict the registration of car calls in advance depending on the use of each floor of the building and the relationship between each floor depending on the use. For example, in an office building, etc., during lunch time, the up button (or down button) on the floor used as an office is pressed, an up call (or down call) is registered, and a car is placed on the floor. This is a case in which, when a response is made, the car calls for the cafeteria floor above (or below) that floor are always registered. In such a case, if the car call on the dining floor is automatically registered when the car responds to the hall call, it is convenient because passengers on that floor do not have to operate destination buttons in the car.

However, in this case as well, when two or more cars have arrived including the assigned car, or when two or more cars have arrived in response to a car call at a landing without a car call, the landing button is not operated. In this case, it will still be impossible to determine which car to board.

This invention improves the above-mentioned problem by changing the notification form of the arrival information alarm at the landing depending on whether car calls are automatically registered or cars where car calls are not automatically registered. To provide an elevator hall notification device which can easily identify cars, guide waiting passengers to cars in which car calls are automatically registered, and prevent a drop in operating efficiency.

Next, the operation of this embodiment will be explained.

Now, assuming that Car No. 1 is on the 2nd floor in the ascending direction and Car No. 2 is on the 1st floor in the ascending direction, the 3rd floor circuit of the landing call cancellation circuit 14AX of Car 1 (Fig. 5) determines the car position on the 3rd floor. Since the signal 43X is "L", the outputs of the AND gates 827 to 829 are all "L", and the third floor up call cancellation command signal 55
Both the UX and the down call cancellation command signal 55DX are at "L". Similarly, the up call cancellation command signal 55UY and the down call cancellation command signal 55DY on the third floor of the No. 2 unit are also set to "L". In addition, in the circuit for the 3rd floor upbound hall (Fig. 4) of the priority response car setting circuit 13B, the 3rd floor car position signal 4 of the No. 2 car
Since 3Y is also "L", AND gate 8
The outputs of 21 and 822 are both “L”,
The outputs of the NOT gates 871 and 872 are both "H", and the third floor up priority response car signals 93UX and 93UY of the first and second cars are both "L".

If a passenger entering the landing on the third floor for the first time presses the destination button 4A for the fourth floor on the hall operation panel 10, the output of the OR gate 851 is "L", so the memory 803 is set and the destination button on the fourth floor is pressed. The destination call registration signal 304 becomes “H” and the destination button light 4B
lights up to let you know that the destination call for the 4th floor has been registered. In addition, since the output of OR gate 853 also becomes "H", memory 806 is set,
The up call registration signal 33U on the third floor becomes "H",
The up call for the third floor is registered. Then, the allocation circuit 13C allocates the No. 1 car that is expected to be able to respond to the uplink call on the 3rd floor in the shortest time, and when the 3rd floor uplink assignment signal 33UX becomes "H", the HL control circuit 14CX of the No. 1 car is assigned. In the circuit for the 3rd floor upbound hall (Fig. 7), the 3rd floor upbound arrival display command signal 56UXa is "L" and the output of the NOT gate 876 is "H", so the output of the AND gate 836 is " H”. Therefore, OR gate 85
The output of No. 9 becomes "H" and the uplight 11UX on the third floor of No. 1 turns on, indicating that No. 1 has been assigned. At the same time, in the third-floor circuit (Fig. 8) of the time control circuit 14FX of Unit 1, the output of the OR gate 861 becomes "H", and the pulse generator 811 emits a pulse signal that becomes "H" for 0.5 seconds. , the forecast chime 12AX on the 3rd floor of car No. 1 rings with a single tone, and the assigned car is also notified by sound.

When Unit 1 departs from the 2nd floor and reaches the 3rd floor, the 4th
In the figure, the 3rd floor car position signal 43X becomes "H" and 3
When it is decided to stop in response to the call for going up the floor, the call answering signal 61X becomes "H". At this time, since the upstream signal 51UX is "H", the output of the AND gate 821 is "H", the output of the AND gate 823 is also "H", and the OR gate 855
The memory 807 is set via. with this,
The 3rd floor ascending priority response car signal 93UX of the No. 1 car becomes "H". Also, in FIG. 7, AND gate 8
The 3rd floor up arrival display command signal 56 which is the output of 35
Since UXa becomes "H" and the output of NOT gate 876 becomes "L", the output of AND gate 836 becomes "L", and the forecast guidance display by uplight 11UX is blocked. On the other hand, in the arrival display state setting circuit 58X, the output of the AND gate 838 is "H" for 0.5 seconds when the periodic pulse signal from the periodic pulse generator 58AX is "H", so the arrival display is performed by the OR gate 860. Status command signal 58Xa
Also becomes "H". Also, for 0.5 seconds when the periodic pulse signal is "L", the output of the AND gate 838 is "L", and the output of the NOT gate 877 is "L".
Since the output of the AND gate 839 is "L", the arrival display state command signal 58Xa, which is the output of the OR gate 860, is "L". in the end,
The output of the OR gate 859 becomes a signal that repeats "H" and "L" at a one-second period ("H" for 0.5 seconds, "L" for 0.5 seconds) while the upstream arrival display command signal 56UXa is "H". The uplight 11UX on the third floor flashes in response to this, indicating that Unit 1 has arrived in the upbound direction.

Further, in FIG. 8, the arrival display command signal 56
When UXa becomes "H" and the uplink priority response car signal 93UX becomes "H", the AND gate 84
The output of 0 becomes "H", the output of OR gate 862 also becomes "H", and the pulse generator 812 outputs 0.5
It emits a pulse signal that becomes "H" for a second, and
The floor arrival chime 12BX will sound in double tones, and the sound will also notify the arrival of the car.

On the other hand, 4 of car call registration circuit 14BX of No. 1 car
In the floor circuit (Fig. 6), the first car arrives at the third floor in the upward direction, and the priority response car signal 93UX is "H".
Then, the fourth floor destination call registration signal 304 is "H", so the output of the AND gate 833 is "H", and the output of the OR gate 858 is also "H".
Therefore, the memory 809 is set and the fourth floor car call registration signal 24X becomes "H". Now, 1
In the car of car number 4, the car call button light 24
The LX lights up to let you know that the car call on the 4th floor has been automatically registered. Therefore, when a passenger on the third floor who is going to the fourth floor boards the car of car No. 1, the car call for the fourth floor has already been registered, so the passenger does not need to press the destination button in the car.

On the 3rd floor, when the car starts to close its door after boarding and alighting in car No. 1, the door opening/closing command signal 59 is activated in Fig. 5.
X becomes "H". At this time, since the door has not been completely closed, the fully closed signal 54X is "L", the output of the NOT gate 875 is "H", and the AND gate 8
The output of 27 also becomes "H". Since the 3rd floor up priority car signal 93UX of car No. 1 is "H", AND
The third floor up call cancellation command signal 55UX becomes "H" by the gate 828. Now, in Figure 3
Since the output of OR gate 851 becomes "H", both memories 803 and 806 are reset, and 4
The floor destination call registration signal 304 becomes "L", the registration of the fourth floor destination call is canceled, and the fourth floor destination button light 4B is turned off. Further, the third floor up call registration signal 33U also becomes "L", and when the registration of the third floor up call is canceled, the third floor up assignment signal 33UX of the first car is reset to "L" in the allocation circuit 13C.

When the car of No. 1 is about to close its door, the call answering signal 61X becomes "L", so as shown in Fig. 4.
The output of AND gate 821 becomes “L” and NOT
The output of the gate 871 becomes "H" and the memory 8
07 is reset, and the 3rd floor up priority response car signal 93UX of car No. 1 becomes "L". On the other hand, in Figure 7
Since the output of the AND gate 835 becomes "L" and the arrival display command signal 56UXa becomes "L",
The output of the AND gate 837 becomes "L", the output of the OR gate 859 also becomes "L", and the third floor uplight 11UX is turned off. When the car of No. 1 completes its door closing, the fully closed signal 54X in FIG. The cancellation command signal 55UX becomes "L", and it becomes possible to register an up call again on the third floor. When the car of No. 1 completes closing and departs from the 3rd floor and reaches the 4th floor, the 3rd floor car position signal 43X becomes "L" and the 4th floor car position signal 44X in Figure 6 becomes "H". .
When the No. 1 machine decides to stop in response to the car call 24X on the 4th floor and stops on the 4th floor, the stop signal 50X becomes "H", so the output of the AND gate 830 becomes "H" and the memory 809 is reset. and 4
The floor car call registration signal 24X becomes "L" and the fourth floor car call button light 24LX turns off, indicating that the car has stopped in response to the fourth floor car call.

The above is an operation when the assigned car (car No. 1) responds to a hall call.

Next, contrary to the above, when Unit 1 is on the 1st floor in the upward direction and Unit 2 is on the 2nd floor in the upward direction,
Assume that the fourth floor destination button 4A on the hall operation panel 10 on the third floor is pressed. At this time, the 4th floor destination call registration signal 304 and the 3rd floor up call registration signal 33U are "H"
Then, the allocation circuit 13C allocates the No. 2 car that is expected to be able to respond to the 3rd floor up call in the shortest time, and when the 3rd floor up allocation signal 33UY of the No. 2 car becomes "H", the No. 2 car is assigned as described above. The uplight 11UY on the 3rd floor is on, and the forecast chime 12 is also on.
AY sounds as a single note. When Unit 2 arrives at the 3rd floor in the ascending direction, in Figure 4 it moves to the 2nd floor in the same way as Unit 1.
The car is selected as the priority response car, the 3rd floor ascending priority response car signal 93UY becomes "H", the 3rd floor ascending light 11UY flashes every 0.5 seconds, and the 3rd floor arrival chime 12BY sounds in double tones. . At the same time, the car call on the 4th floor is automatically registered in the No. 2 car.

Now, when Unit 2 was arriving at the third floor in response to the call for going up to the third floor, Unit 1 departed from the first floor with passengers going to the third floor and decided to stop while going up to the third floor. do. At this time, in Fig. 4, the 3rd floor car position signal 43X of car No. 1 is "H", and the call answering signal 61
Since X is "H" and the up direction signal 51UX is "H", the output of the AND gate 821 is "H", but the 3rd floor up priority response car signal 93 of the second car is
Since UY is "H", the selection circuit 813
The output of OR gate 857 is "H", NOT gate 8
Since the output of 73 is "L", the output of AND gate 825 remains "L", and car No. 1 is not selected as the priority response car, and the 3rd floor priority response car signal 93UX of car No. 1 is selected as the priority response car. remains at "L". Therefore, since the output of NOT gate 877 in FIG. 7 becomes "H", periodic pulse generator 58
During the 3 seconds when the periodic pulse signal from BX is "H", the output of the AND gate 839 is "H",
The arrival display state command signal 58Xa also becomes "H".
Also, for 0.5 seconds when the periodic pulse signal is "L", the output of the AND gate 839 is "L",
The arrival display state command signal 58Xa also becomes "L".
In the end, the upstream arrival display command signal 56UXa is "H"
While the lights are on, the uplight 11UX on the third floor will blink for 3 seconds and turn off for 0.5 seconds. Furthermore, in FIG. 8, even if the arrival display command signal 56UXa becomes "H", the third floor ascending priority response car signal 93UX remains "L", so the AND gate 840 and
Both outputs of OR gate 862 are "L". Therefore, the output of the pulse generator 812 does not become "H", and even when the first machine reaches the third floor, the third
Floor arrival chime 12BX is not rung.

When planes 1 and 2 are arriving on the 3rd floor in the upward direction, if a passenger going to the 5th floor enters the platform late and presses the destination button 5A on the 5th floor, the priority response car will be activated as described above. The car call for the 5th floor is registered in car No. 2. At this time, the uplight 1 on the third floor of Unit 2, which is a priority response car, and Unit 1, which is not a priority response car.
Since the blinking patterns of 1UY and 11UX are different,
Passengers can easily identify the car in which the 5th floor car call is automatically registered, that is, car No. 2, and can board the car without making a mistake. Further, since the arrival chime of the first car, which is not a priority response car, does not ring, passengers will not be guided by the ringing of the arrival chime to board the first car by mistake, and passengers will not be confused.

When Unit 2 starts closing its door, the up call registration signal 33UY on the 3rd floor and the destination call registration signals 304 and 305 on the 4th and 5th floors become "L", and the 3
The upstream assignment signal 33UY becomes "L". Just before the door closes, the 3rd floor up priority response car signal 93UY is also reset to "L" in Figure 4.
The output of OR gate 857 is "L", the output of NOT gate 873 is "H", and if the No. 1 unit is on the third floor and responding in the upward direction, the output of AND gate 821 is "H". , the output of the AND gate 825 becomes "H". Therefore, OR
The output of the gate 855 becomes "H", and the memory 80
7 is set and car No. 1 is selected as the priority response car on the third floor.

When the first car is newly selected as the priority response car,
Unit 1's 3rd floor uplight 11UX will be changed from blinking at a 3.5 second cycle to blinking at a 1 second cycle. Also, the 8th
The outputs of the AND gate 840 and OR gate 862 in the figure are "H", so the arrival chain 12 on the third floor
BX sounds with two consecutive notes.

Thereafter, when the destination button 4A or 5A for the 4th or 5th floor is pressed, the car call is automatically registered in car number 1, which is the priority response car. (In addition, even if an up call or a down call is registered in the allocation circuit, if the priority response car is selected, the allocated car will not be selected.) In the above example, the allocated car (unit 2) is responding. At the boarding point of
Although the case where another car (car No. 1) arrives in response to a car call has been described, the same applies to the case where car No. 1 and car No. 2 arrive in response to only a car call. In this case, the car that arrived first is selected as the priority response car, and a guide is displayed at the landing so that passengers can know which car will automatically register the car call even before they enter the hall. Therefore, passengers who have entered the hall can board the car more calmly than in the case where a car with automatic car call registration is displayed after operating the hall button.

FIG. 9 shows another embodiment of the invention.

In this embodiment, the periodic pulse generator 5 of FIG.
8BX and AND gate 839 are not used, and the output of NOT gate 877 is sent to OR gate 860.
It is one of the inputs.

Car No. 1 arrives at the 3rd floor in the up direction, is selected as the priority response car, and sends the 3rd floor up priority response car signal 93UX.
When becomes “H”, the arrival display state command signal 58
Xa becomes a signal that repeats "H" and "L" with a one-second cycle ("H" for 0.5 seconds, "L" for 0.5 seconds), and causes the uplight 11UX on the third floor to blink. When the No. 1 car is not selected as the priority response car, the output of the NOT gate 877 is always "H", so the arrival display status command signal 58Xa is also always "H", and the No. 1 car arrives at the third floor in the upward direction. When I did that, the 3rd floor uplight 11
The UX will turn on without blinking. In this way, the arrival information display for the priority response car is a flashing HL,
The arrival information display for cars that are not priority response cars has a different display format, such as a lighting HL.

FIG. 10 also shows another embodiment of the invention.

In this embodiment, the periodic pulse generator 5 of FIG.
8BX, AND gate 839, OR gate 860 and NOT gate 877 are removed, AND gate 83
The output of No. 8 is the arrival display state command signal 58Xa.

If the first car is not selected as the priority response car,
Since the output of the AND gate 838 is always "L", even if the No. 1 vehicle arrives at the third floor in the upward direction, the third floor upward light 11UX remains off. In this way, the arrival information display for priority response cars is a flashing HL, and the arrival information display for non-priority response cars is
The display format is different, such as HL being turned off.

Note that it is also possible to implement as follows.

(a) In addition to HL and chimes as visual alarms, use visual indicators such as liquid crystals, light emitting diodes, cathode ray tubes, etc. to provide arrival guidance using figures, letters, etc., and auditory announcements such as audio announcements.

(b) As a means of differentiating the notification format for cars in which car calls are automatically registered and cars in which car calls are not automatically registered, HL
In addition to using the lighting status (on, off, or blinking, as well as the blinking cycle and blinking ratio (ratio of lighting time to off time when blinking)) and chime ringing status (ringing or non-ringing), the color and brightness of the HL. or change the chime volume, number of rings, pitch, melody, etc. (For those that display arrival information using figures, letters, etc., it is possible to clearly distinguish between cars for which car calls are automatically registered and cars for which car calls are not registered.) Using the point in time when the destination button is pressed, the HL arrival guide display format for cars that are not priority response cars is made to differ.

(d) This also applies to elevators that only provide arrival guidance without providing forecast guidance for assigned cars. It is also applied to elevators that allocate the most suitable car for each destination call and notify the assigned car for each destination call through a destination floor display. In this case, it is possible to clearly display the arrival of a car whose car call is automatically registered to passengers who are in a position where it is difficult to see the destination floor on the destination floor display.

(E) Simply provide an up button and a down button at the landing,
The present invention is also applied to elevators that automatically register the car call of a predetermined floor to a predetermined car when these are operated.

(F) As a means of specifying the destination floor at the landing, use a dial or numeric keypad destination floor button.

As described above, in this invention, a car call is automatically registered in an elevator that automatically registers a car call on the destination floor corresponding to a button at a landing operated by a passenger to one of a plurality of cars. By selecting a priority response car and making the notification format of the hall alarm for cars that are not automatically registered different from this car, passengers can easily distinguish between cars whose car calls are automatically registered, without getting confused. It is possible to board the car and prevent a decrease in elevator operation efficiency.
