Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an elevator, and more particularly to a control device for an elevator equipped with an emergency dedicated hall call input means.

[0002]

2. Description of the Related Art A control system called group management control is one of the elevator cars installed in a plurality of elevators (usually 3 or more) when a landing call is generated, which is the most suitable elevator to handle the landing call. The car is immediately selected and assigned, and the assigned car responds to the floor where the landing call occurs and services.

[0003] In addition, when traffic demand increases, such as in the morning work hours, in the evening, when leaving the office, and during lunch hours, and when traffic decreases during nights, holidays, etc., the traffic changes peculiar to the building. Together with this, the elevator is controlled for efficient operation while switching to a preset operation mode.

When a special customer arrives, a special elevator service (car) is set in the hall by a special customer service button installed at the reception of the building, etc. There is a service to do.

[0005] In general, the cage for the special customer is a fixed basket that is closer to the position than the reception so that the special customer is not moved as much as possible. Since this special customer-only operation is performed only very infrequently, it is usually used as an elevator for general customers, and when the special customer uses it, the fixed elevator machine (fixed car) is switched to the special customer-only operation. I often take a method. Therefore, switching to the special customer-only operation is performed after waiting for the service of general customers.

[0006]

Recently, there is an increasing demand for applying this special customer-only operation to other uses. Not only general office buildings and condominiums but also hospitals tend to be upsized by introducing the latest equipment.In such large hospitals, multiple elevators are usually installed to perform group management control. It may be used for purposes different from general office buildings and condominiums.

[0007] For example, when a doctor or a nurse has to rush to a hospital room urgently, a patient is carried on a stretcher on a specific treatment room, or a medical instrument or medicine is urgently carried on a table. There are times when you will need to use the elevator.

In such a case, it is necessary to urgently call an elevator from a specific landing, use it exclusively, and head urgently to the intended floor. Therefore, first of all, it is conceivable to use the conventional special customer-only operation.
Then you can use the elevator exclusively,
You can reach the destination floor faster than you can drive normally. By the way, in the case of special customer-only operation, avoid not move as much as possible the special guests, also, had been promptly fixed whether to dispatch in advance what the car so that Norikomeru to the elevator without confusion during the response. Therefore, the car does not always arrive earlier than the other cars, and even if there is another car that can arrive earlier, the car cannot be dispatched. On the other hand, in the case of special passenger only driving, the person who actually gets on the elevator does not actually operate the landing call, so rather registering a normal landing call is more convenient and the purpose of this driving is faster. It was about arriving at the destination floor and driving exclusively so as not to get on board with ordinary passengers. In addition, it is usually used as an elevator for general passengers, and when it is used by a special passenger, it is switched to a dedicated operation. Therefore, the switching is performed after waiting for the service of the general passenger to be completed.

Therefore, when a large number of passengers are in the car, the operation is switched to the special passenger only operation after passing through all the destination floors, which takes time and cannot be said to be a suitable operation method in an emergency. Therefore, it is possible to dispatch the elevator that arrives the earliest, but when using it in an emergency at a hospital, it is often waiting with a stretcher at the landing, so if you do not fix the car that responds Was tough.

[0010] Therefore, an object of the present invention is, when an elevator is used in an emergency to reach a destination floor, dispatch the elevator that can arrive earliest with the highest priority so that passengers can reach the intended floor as soon as possible.

[0027]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the first embodiment. The elevator control device 1 is a part that controls the operation of the elevator, and controls the motor control device 2 to control the raising / lowering operation of the car 3 and the opening / closing operation of the door.

The elevator controller 1 includes an operation controller 4
1, the allocation control unit 5 is provided, and although one is shown in FIG. The operation control unit 4 controls the operation of each elevator according to a command from the allocation control unit 5. The allocation control unit 5 calculates and allocates a predicted arrival time for a landing call.

In the car 3, a car call input / output control unit 6, a car call registration device 9, a car notification control unit 10 and a voice synthesizing device.
11, and the in-car notification control unit 10 includes the voice synthesizer 11,
The car call input / output control unit 6 controls the car call registration device 9.

The general hall call registration devices 7a to 7n are arranged on each floor, and the hall call signals from the hall call registration devices 7a to 7n are input to the elevator control device 1 via the hall call input / output control units 8a to 8n. The elevator control device 1 also outputs a landing call registration signal.

The landing call registration devices 7a to 7n are
Multiple units are installed on one floor, but only one is shown in Fig. 1. Similarly, emergency landing call registration device 12a
˜12n, the emergency dedicated hall call signal from each registration device 12 is input to the elevator control device 1 via the emergency dedicated hall call input / output control units 13a to 13n, and the elevator control device 1 registers the emergency dedicated hall call. The signal is output. Further, the allocation control unit 5 in the elevator control device 1 to which the emergency landing call registration signal is input calculates the waiting time from the position of each car, etc., and operates the operation control unit 4 for the car determined to arrive earliest. Give commands via and make the car respond.

The present invention is characterized in that the emergency dedicated driving number is not fixed, but the number of the vehicle having the minimum predicted waiting time condition is selected according to the position condition of the car and the emergency dedicated hall call generation floor. The operation will be described using a flowchart.

Each process in the allocation control unit 5 is divided into units called tasks and each process is performed. First, the contents of the assignment processing task will be described with reference to the flowchart of FIG. Here, since it is the process of detecting the most suitable car for responding to the emergency dedicated hall call, the waiting time t _n (n = 1, until the response to the emergency dedicated hall call is made for each car.
2. Calculate the number of cars.

First, in step 1, t _n is set to an initial value 0. Next, the waiting time is calculated excluding the cars that are already in emergency operation, so it is determined in step 2 whether or not emergency operation is in progress.
If so, the waiting time of the next car is calculated excluding that car (step 9). If not, it is determined whether the car is running or decelerating (step 3), and the waiting time is calculated differently depending on whether it is not applicable.

In step 4, the waiting time t _n is calculated when the car is decelerating or stopped, and the waiting time t _n is the estimated time required for the car to depart and the time until the car reaches the emergency dedicated hall call generation floor. It is the total of the traveling time (step 8).

If the car is running, it is determined whether the car has a registered car call (step 5) or is running in the opposite direction to the emergency landing call (step 6). If there is a registered car call or the car is traveling in the opposite direction, the time for landing at the nearest floor is added to the waiting time t _n in step 7. In other words, when there is a car call, it is necessary to temporarily land on the nearest floor and unload the passengers inside, and even when traveling in the opposite direction, it is necessary to temporarily stop at the nearest floor and change the direction. Because there is. Then, as in the case where the car is stopped, in step 8, the time during which the car travels to the floor for the emergency landing call generation is the waiting time t _n.
Add to The reason why the traveling time is simply added here is that the registered general landing call call and the car call are immediately canceled and the vehicle is directly driven to the floor for emergency landing call generation.

When the waiting times t _n of all the units are calculated, t _n of all the units are compared (steps 9 to 10). Therefore, if all the waiting times t _n are 0 (step 11), it means that all the units are in emergency operation, so the emergency dedicated hall call information is saved in a queue type buffer (described later) (step 13). If not 0, the assignment is output so that the car with the minimum t _n responds to the emergency dedicated hall call.

Next, the operation of saving the emergency landing call described above in the buffer will be described with reference to FIG. First, in step 1, it is determined whether or not there is a new emergency dedicated hall call, and if Yes, it is detected whether the emergency dedicated hall call buffer is empty (step 2). Then, if it is not empty, the call information is added to the emergency hall call buffer in step 3, and if the buffer is empty, the task of the allocation process is started in step 4 and the allocation process described in FIG. 2 is executed. Be seen. Here, the emergency dedicated hall call buffer will be described with reference to FIG.

The buffer has a sufficient size, and has a ring structure in which the information is saved up to the end of the buffer and the information returns to the beginning again. It also has two pointers, pointer A indicates where to save information next, saves sequentially from the top, and advances one pointer down each time it saves. The pointer B points to the place where the information is taken out first. The information about the direction and the floor where the emergency landing call was saved is saved for each byte.
Such a buffer is created in the memory of the allocation control unit 5 in FIG.

Next, returning to FIG. 3, in step 5, it is judged whether or not the emergency dedicated hall call buffer is empty,
If it is not empty, it is determined in step 6 whether there is a unit that has returned to normal operation. If there is a normal operation return unit,
The emergency exclusive hall call information is extracted from the location indicated by the pointer B described in FIG. 4, and the task of the allocation processing is activated, and the pointer B is moved down by one. In other words, the call information is retrieved and assigned in the order of saving in the buffer.

With the above-mentioned procedure, it is possible to respond to the generated emergency dedicated hall call by the car expected to arrive the earliest, and not to respond to other general hall calls or car calls. Since it does not respond to other emergency landing calls, it can arrive at the destination floor in the minimum time.

Next, the operation of the second embodiment of the present invention will be described with reference to the flowchart of FIG. First, in the assignment control unit 5, when it is determined in step 1 that the emergency operation is switched, it is detected in step 2 whether the call is a general landing call that has already been registered, and if there is a call, it is canceled. (Step 3). In addition, it detects whether or not the car will land on the nearest floor due to car call cancellation (step 4), and when landing on the nearest floor, activates the allocation process for allocating another elevator to the floor. (Step 5). The above processing is carried out for all units (step 6).

Next, the above-mentioned car call canceling operation will be described with reference to the flowchart of FIG. In the operation control unit 4, it is determined whether or not the car is for emergency switching (step 1), and if so, it is determined whether or not there is a registered car call, and if there is a car call, the car call is canceled. (Steps 2 to 3).

Then, the nearest floor landing command is output to the motor control device 2, and the allocation control unit 5
Information on the nearest floor, which is a trigger condition for the allocation process for allocating another elevator for the passengers who are unloaded on the nearest floor, is output (steps 4 to 5).

When the person arrives at the nearest floor, a command signal for outputting a voice is output to the in-car notification control unit 10 (steps 6-).
7). The in-car notification control unit 10 receiving the voice output signal outputs the voice signal from the voice synthesizer 11. This informs ordinary passengers in the car that they have switched to emergency driving, prompts them to exit the elevator when the door is open, and informs them to immediately switch to another elevator.

Therefore, since the elevator assigned to respond to the emergency dedicated hall call cancels not only the registered hall call assignment but also the car call, it is possible to reach the emergency dedicated hall call generation floor in a minimum time. .
When canceling the car call, the passengers in the car can be guided to prevent the passengers from being confused.

Next, a third embodiment will be described with reference to the drawings. FIG. 7 is a block diagram showing the configuration of the third embodiment. Elevator 1 allocation control unit 3, operation control unit 4, general hall call registration devices 7a to 7n, general hall call input / output control units 8a to 8n, emergency dedicated hall call registration device 12a.
.About.12n, and the emergency dedicated hall input / output control units 13a to 13n have the same configurations as those in the previous embodiment, the description thereof will be omitted.

14a to 14n are hall notification control means installed in each hall, and 15a1 to 15ah and 15n1 to 15nh are hall voice synthesizers installed near the doors of the respective cars in each hall. In the above configuration, when the car to respond to the emergency dedicated hall call is first determined by the allocation control unit 5, the hall notification control means of the emergency dedicated hall call generation floor.
The code number indicating which car responds to 14n and which message should be output is output. Then, the hall notification control means 14n decodes the content of the code number, and immediately issues a message output command of "This elevator performs emergency operation" to the hall voice synthesizer 15ah of the car. Here, the hall voice synthesizer 15
Will be described with reference to FIG.

A message having a predetermined content is added to the memory in the hall voice synthesizer with a code number added, and the corresponding message is received in response to the code number signal from the hall notification control means 14a to 14n. Output. The hall notification control means 14a to 14n determine which code number is output to which hall voice synthesizer according to a command from the operation control unit 4 and the allocation control unit 5.

As described above, it is possible to immediately determine which car responds when an emergency hall call is generated at the hall, and in the hospital, a stretcher or medical equipment carrying a patient is placed. It is possible to make a trolley stand by in front of the car that responds, and to quickly get in when responding to the car.

In the first embodiment, the case where the car is stopped on that floor was not particularly described, but in that case, an emergency exclusive hall call is assigned to the car that is stopped on that floor, and a plurality of cars are assigned. When the stand is stopped, the car near the side where the call is registered can be assigned to minimize the time.

Further, it becomes more effective to prevent the call from being registered unnecessarily by using the secret code call registration device for the emergency landing call. Further, the same effect can be obtained by using the in-car display instead of the voice synthesizer as the in-car notification means in the second embodiment.

[0053]

As described above, according to the present invention, when an elevator is used in an emergency to reach a destination floor, the elevator that can arrive earliest is assigned the highest priority, and which elevator arrives. It is possible to provide an elevator control device that informs the passengers of such a situation, causes the passenger to arrive at the intended floor as soon as possible, and prevents confusion of general passengers.
