Description

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

It is well known that elevator landings are provided with a landing button, and when operated, a landing call is registered and an elevator car can be called to that floor.

However, if a power outage occurs after hall calls have been registered, all previously registered hall calls will be cancelled. Therefore, even if the power outage is restored and the elevator becomes serviceable, the previous state (waiting time for calls) will have all been cancelled, so services for hall calls will not be equal. In other words, both passengers who have been waiting for a long time at the boarding point and passengers who have been waiting for a short time are all subject to the same service conditions.

This invention is intended to improve the above-mentioned problem. During a power outage, calls that have been registered continuously for a predetermined period of time or more are memorized, and after the power is restored, the car is given priority to respond to the registered calls. To provide an elevator hall call registration device which allows elevator services to be equally performed for hall calls after return.

Reference numerals 18 to 21 are reset coils for resetting each of the above-mentioned keep relays 1UKS to 3DKS, respectively, and these reset coils 18 to 21 are used to reset the above-mentioned call release relays 1 on the 1st to 3rd floors.

They are called 2UCR _c , 2DCR _c , and 3DCR _c and are connected in parallel between power lines L1 and L2 via a parallel circuit with normally open contacts 15e to 15h of cancel relay 15.

Next, the operation of this embodiment configured as described above will be explained.

Now, assuming that the DC power supplies (+) and (-) are normal and there are no hall calls or car calls, the first timer relay 10 shown in FIG. After 3 minutes, pick it up and hold it in that state. That is, under normal conditions, it is always picked up. When the first timer relay 10 is picked up, its contact 10
A to 10c and 10e are closed, and contact 10d is opened. Therefore, the nominal cancel relay 15 is picked up, and each reset coil 1 is thereby picked up.
1 to 14 and 18 to 21 are excited to reset the corresponding call keep timers 1UKR to 3DKR and keep relays 1UKS to 3DKS. Then, when 0.5 seconds have elapsed since the start of energization to the second timer relay 16 due to the closing of the contact 10c accompanying the pickup of the first timer relay 10, the second timer relay 16 is picked up and its normally closed contact 16a is opened. This causes the call cancel relay 15 to drop out. When the nominal cancel relay 15 drops out, each reset coil 11-14 and 18-21 is demagnetized.

In this state, when the second floor up call registration button 2U shown in FIG. 1 is pressed, the second floor up call registration relay 2UR picks up and its contact 2
Self-retained by UR _a and normally open contact 2
When UR _b is closed, the second floor up response lamp 2UL is lit, indicating that the second floor up call has been registered. Here, assuming that the car is stopped on the first floor, as the call registration relay _2UR is picked up, as shown in FIG.
The up direction command relay 81U is picked up by the closed circuit of the relay 81U-(-), and the elevator car is operated up.

On the other hand, when the up call registration relay 2UR on the second floor is picked up, the (+)-contact 1 shown in Figure 2
0a - Contact 2UR _c - Keep timer 2UKR -
(-) closed circuit is formed and keep timer 2
Start energizing UKR. When 30 seconds have elapsed from the start of power supply, the keep timer 2UKR picks up and stores the waiting time for the call up to the second floor landing. In this case, if the elevator car arrives in less than 30 seconds in response to the second floor hall call, the keep timer 2UKR will not be picked up.

Similarly, the (+)-contact 10e shown in FIG.
A closed circuit of - contact 2 UR _g - keep relay 2 UKS - (-) is formed, and keep relay 2 UKS picks up and stores the call up the hall on the second floor.

Also, due to the above-mentioned 2nd floor up hall call, 2 cars were
When you get near the landing on the floor, the car position detection contact 2US
(See Figure 1), 2a is closed, so (+) - contact 17f or 2UKR _c - contact 2 shown in Figure 4
UR _f - Contact 2a - Contact 81U _b - Relay 438 -
A (-) closed circuit is formed, which picks up the hall call stop detection relay 438 and issues a stop command. And contact 31X _a of stop decision relay
is closed, the (+)-contact 31 shown in FIG.
X _a - Contact 81U _a - Position detection contact 2US - Relay 2
A closed circuit of UCR-(-) is formed, picks up the up call release relay 2UCR on the second floor, opens its normally closed contact 2UCR _a , and thereby drops out the up call registration relay 2UR on the second floor, and
The response lamp 2UL for going up the floor goes out. Now 2
The call for going up the floor will be cancelled.

Furthermore, the up call keep timer 2UKR on the second floor is dropped out by the closed circuit of the (+)-reset coil 12-contact _2UCRb -(-) shown in FIG. -Contact 2UCR _c -2 due to closed circuit of (-)
Drop out the upstairs call keep relay 2 UKS. Furthermore, if a passenger who boarded the car on the second floor presses the car call button on the third floor, contact C3 shown in FIG. It turns out.

Next, suppose that a power outage occurs when, for example, an up call on the second floor and a down call on the third floor are registered. In this case, by pressing the up registration button 2U on the second floor,
The call registration relay 2UR picks up, thereby keeping the upstream call keep relay 2UKS on the second floor. Furthermore, if 30 seconds have passed since the call was registered, the second floor up call keep timer 2UKR operates to keep the second floor up call. That is, even if the DC power supply is turned off due to a power outage and all the call states of the hall up to that point are cancelled, the waiting time (duration time) of the call up to the hall on the second floor will be remembered.

Further, if 30 seconds have not elapsed since the third floor down call was registered, the third floor down call keep relay 3DKS is kept, but the third floor down call keep timer 3DKR is not kept.

Afterwards, if the power is restored and there are passengers on the second floor, the passenger detection relay contact 2X _a on the second floor will close,
Since the upward call keep relay contact 2UKS _a on the second floor is also closed, the (+) - contact 2X _a - shown in Figure 1
Contact 2UKS _a - Contact 2UCR _a - Relay 2UR - (-)
A closed circuit is formed, and as a result, the up call registration relay 2UR on the second floor is picked up, and the response lamp 2UL is also turned on. Also, if there are passengers on the third floor, the third floor down call registration relay 3DR will be picked up in the same way. Even if the power is restored, the first timer relay 10 does not perform the pick-up operation until 3 minutes have passed, so the kept up-call on the second floor is assigned a car with the highest priority over the call on the other floor.

That is, even if the first timer relay 10 is in the drop-out state, the up-call keep timer 2UKR on the second floor maintains the pick-up state.
When the up call registration relay 2UR on the second floor is picked up, a closed circuit of (+)-contact 10d-contact 2UR _d -contact 2UKR _a -relay 17-(-) is formed as shown in FIG. 17
, and open the normally closed contacts 17a to 17h shown in FIGS. 3 and 4. As a result, for example, if the car is stopped on the first floor, (+) - contact 2UKR _b -2UR _e - car position detection contact 3b - car position detection contact 3b - relay 81 shown in FIG.
U-(-) closed circuit, upward direction command relay 81
U is picked up, and the car is brought to the second floor preferentially by a circuit not shown. At this time,
Although call registrations are accepted for hall calls other than the above-mentioned up-calls on the second floor, the corresponding keep timers are in a dropout state, and the hall call stop detection circuit system is released due to the pick-up of the call detection relay 17. 2
Car assignment is suspended for hall calls other than floor calls.

When the car assigned to the up call on the second floor runs in the up direction and the car position detection contact 2a on the second floor is closed, (+) - contact 2 UKR _c - contact 2 UR shown in Fig. 4 _f - Contact 2a - Contact 81U _b -
A closed circuit of relay 438-(-) is formed, and the hall call stop detection relay 438 is picked up to issue a stop command. On the other hand, contact 31 of the stop decision relay
When X _a closes, the up-call release relay 2 on the second floor
When the UCR picks up, opening its normally closed contact 2UCR _a and closing its normally open contacts 2UCR _b and 2UCR _c causes the second floor up call registration relay 2UR to drop out, thereby causing the second floor up call keep timer 2 UKR and 2nd floor up call keep relay 2
UKS is dropped out, and the call detection relay 17 is dropped out by opening their normally open contacts 2UR _d or 2UKR _a , and at the same time, the up response lamp 2UL on the second floor is turned off. The car also stops at the landing on the second floor.

Furthermore, when 3 minutes have passed after the power is restored, the first timer relay 10 picks up and drops out the call detection relay 17 by opening its normally closed contact 10d, and at the same time drops out the call detection relay 17 by closing its normally open contact 10b. Each reset coil 11 to 14 and 18 is picked up and shown in FIG.
21 is energized while the second timer relay 16 is picked up with a delay of 0.5 seconds, thereby resetting the call keep relay and keep timer for other floors (here, the down call for the third floor). Also,
If the call detection relay 17 is dropped out,
Its normally closed contacts 17a-17h are closed, allowing the elevator car to service all hall calls. At this time, the normally open contact 10 shown in FIG.
Since a is closed, a hall call is registered, and if the call registration state elapses for a predetermined period of time (30 seconds), the waiting time for each call will be stored in the keep timer.

Furthermore, even if three minutes have not passed after the power is restored, if all the kept long-waiting calls are cancelled, the call detection relay 17 will drop out in the same way.
Service will be available for all boarding calls.

In addition, in the above-mentioned embodiment, only the up call on the second floor was explained, but the same applies to the hall call on other floors, and the explanation thereof will be omitted. Furthermore, the number of floors is not limited to the third floor as in the embodiment, but it goes without saying that the present invention can be similarly applied to elevators with more floors than that.

In addition, in the example, automatic registration of calls after a power outage is restored is limited to only when passengers are detected and there are passengers in the hall, but it is also possible to automatically register calls regardless of the presence or absence of passengers. It is also possible to limit automatic registration to only long-waiting calls.

As described above, according to the present invention, when a call signal is registered continuously for a predetermined time or more under a situation where power is supplied to the elevator and the car can respond, the counting storage means stores this call signal,
This memory is retained even during a power outage, and when the power is restored next time, the car is made to respond to the stored call signal in preference to the call signal registered after restoration.

Therefore, when a power outage occurs, a person who has already been waiting for a car for a predetermined period of time or more before the power outage occurs can receive a car response with priority over a call signal registered after the power is restored. In other words, since the cars can be managed taking into consideration the waiting time before a power outage, even if a power outage occurs, it has the effect of reducing inequality in service to customers before the power outage occurs.
