Abstract

PURPOSE:To carry passengers effectively to their respective destination floors by equipping an operation control means with a function to give a cage call command in priority only when the frequency of cage call occurrences sensed by a cage call frequency sensing means for a backup control means is low in case the place-of-getting-on call registration system is in failure. CONSTITUTION:When a call power supply signal S1 is downed and no place-of- getting-on registration can be made any more, a place-of-getting-on call registration abnormality judging part 6 gives an abnormality judge signal to the backup judgement control part 5-3 of an elevator operation control device 5. Now the control part 5-3 gives a signal showing abnormality in the place-of-getting-on call to a call response control part 5-1 and also a backup command for stopping the cage at each floor to a travel control part 5-2. At this time, a cage call frequency judging device 7 computes the mean time of intervals of cage call occurrences, and the result is given as the cage call frequency to the control part 5-3. The control part 5-3 stops the cage entered into the control part 5-2 at each floor when the cage call frequency is higher than the set value, and responds to the cage call when lower.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention improves the backup function of car operation control when registration of a hall call registration signal becomes impossible due to an abnormality in the hall call registration system. 111% equipment for elevators.

(Prior art) Elevator control equipment, especially for operating multiple elevators at the same time υ1! ! Elevator group management systems are often installed in large-scale buildings, so if service to customers becomes unavailable due to a breakdown, the impact will be far greater than in a small building. Become.

Therefore, in case a failure occurs, such an elevator control device may be designed to partially reduce the elevator's control performance to avoid a complete stop, or to enable the elevator to operate in normal areas. A backup control system that allows the train to operate within the specified range, in other words, incorporates the concept of failsoft to minimize service deterioration.

2. Description of the Related Art Conventionally, one of the backup control methods for elevator control devices is one for a failure in a hall call system.

For example, in an elevator group management system, this backup control method divides the elevators into two groups, and controls the operation of the elevators by stopping one group at an odd-numbered floor and the other at an even-numbered floor. If a car is registered, the car call will also be answered.

Therefore, by introducing such a backup control method into the elevator control device, even if a hall call cannot be registered due to a failure in the hall call system, either one car or the other car will be on the floor that the passenger is holding. Since the train will be stopped, there will be no loss of service to passengers.

(Problem to be solved by the invention) However, in elevator operation control using such a backup control method, even though there are actually no waiting passengers on any floor, the elevator cars divided into each group are shared. Make sure to stop on every floor,
Passengers riding in a car are forced to stop several times on unoccupied floors before reaching their destination floor. Particularly during times when there are few passengers, there are many cases of invalid driving, which increases the discomfort caused to passengers inside the car.

The present invention makes it possible to efficiently transport passengers in the car to the destination floor by giving priority to car calls only when car calls are infrequent when the call registration system is out of order. It is an object of the present invention to provide an elevator control device that can improve service without giving rise to problems.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention provides a hall call registration signal,
A car operation control means for controlling the operation of the car by responding to the call when a car call registration signal is input; a hall call registration abnormality determination means for determining whether or not there is an abnormality in the hall call registration system; and backup control means for instructing the operation control means to operate the car by stopping or skipping each floor when the hall call registration abnormality determination means determines that there is an abnormality in the hall call registration system. Control 1I
In the car call registration system, when the hall call registration abnormality determining means determines that there is an abnormality in the hall call registration system, the car call generation system inputs a car call registration signal and detects the car call occurrence frequency from the car call generation time interval. A frequency detecting means is provided, and the backer 1111B means has a function of giving priority to a car call command to the ship operation control immediate means only when the car call occurrence frequency detected by the car call occurrence frequency detecting means is low. It is designed to have the following.

(Function) In the elevator control device having such a configuration, when an abnormality in the hall call registration system is detected, the car call frequency is detected,
If this car call frequency is low, the original backup i+
Since it is possible to respond to a car call with priority over the JIII function of stopping the car at each floor or skipping the car, it is possible to improve the service to passengers.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block circuit showing an example of the configuration of an elevator control device according to the present invention.

In FIG. 1, reference numeral 1 indicates a hall call registration display button switch provided in the elevator hall of each floor. When this hall call registration display button switch 1 is pressed, the hall call registration signal for that floor is registered in the hall call registration section 2. . Reference numeral 3 denotes a car call registration display button switch provided in the car. When the car call registration display button switch 3 is pressed, the car call registration signal is registered in the car call registration section 4.

A hall call registration system power signal S1 is input to the hall call registration unit 2, and the hall call Ω registered in this hall call registration unit 2
The green signal is input to the elevator operation control device 5. Reference numeral 6 denotes a hall call registration abnormality determination unit 6, and this hall call registration abnormality determination unit 6 receives a power signal S1 for the hall call registration system.
Further, a hall call registration signal and its registration status signal are respectively inputted from the hall call registration unit 2, and from these signals it is determined whether or not there is an abnormality in the hall call registration system, and the determination signal is inputted to the elevator operation control device 5. Ru.

Further, the car call registration signal registered in the car call registration section 4 is input to the elevator operation opening device 5, and is also input to the car call occurrence frequency determination bag N7. This car call occurrence degree determination device @7 includes a car call occurrence timer 7-1 which operates when a determination signal S2 indicating a failure is inputted to the hall call registration system from the hall call registration abnormality determination unit 6; 7-
1, the car call generation detection unit 7-2 detects the car call registration signal inputted from the car call registration unit 4, and the operation signal from the car call generation timer 7-1 and the car call generation detection unit 7-.
2, an average occurrence time calculation unit 7- calculates the average time of the car call occurrence interval based on the detection signal from the car call occurrence frequency, and inputs this to the elevator operation control device 5 as the car call occurrence frequency.
It consists of 3.

On the other hand, the elevator operation control device 5 receives the hall call registration signal registered in the hall call registration section 2 and the car call registration signal registered in the car call registration section 4, and receives a call response command and a car call signal. Response control unit 5-1. When a call response command is received from the call response control unit 5-1, a car call signal 1 is sent from the running control unit 5-2 and the call response control unit 5-1, which control the running and stopping of the car, to the hall call registration abnormality determination unit 6. The determined judgment signal and the car call occurrence frequency determined by the average occurrence time calculation unit 7-3 of the car call occurrence frequency determination device 7 are input, and are sent to the travel control unit 5-2 when an abnormality occurs in the hall call registration system. It is composed of a backup determination control section 5-3 that gives a backup command. This backup determination control section 5-3 outputs a normal response command to the traveling control section 5-2 when there is no abnormality in the hall call registration system, and outputs a normal response command to the travel control section 5-2 when there is an abnormality in the hall call registration system and If it is determined that the call occurrence frequency is higher than a predetermined value, a command is given to the travel control unit 5-2 to stop the car at each floor, and if there is an abnormality in the hall call registration system and the When it is determined that the car call occurrence frequency is lower than a predetermined value, the traveling control unit 5
-2 has the function of giving a stand-up command to respond to a car call.

Next, the operation of the elevator control device configured as described above will be described.

First, when the elevator system is normal, when the current hall call registration display button switch 1 is pressed, a hall call registration signal is registered in the hall call registration section 2, and the response display signal is sent to the hall call registration display button. Output to switch 1. Further, when the car call registration display button switch 3 is pressed, a car call registration signal is registered in the car call registration section 3, and the response display signal is sent to the car call registration display button switch 3.
is output for. When the hall call registration signal and car call registration signal registered in the hall call registration unit 2 and the car call registration unit 3 are respectively input to the call response control unit 5-1 of the elevator operation control ill device 5, The call response control section 5-1 issues a control command to the travel control section 5-2 in order to respond to the hall call registration signal and the car call registration signal. The travel control section 5-2 controls the elevator car by the call response control section 5-2.
A series of controls such as start, deceleration, and stop are performed according to commands from 1.

In this case, since no abnormality in the hall call registration system has been detected by the hall call registration abnormality determination unit 6, the backup determination control unit 5-3 issues a normal response instruction to the travel control unit 5-2. Therefore, the elevator responds to passenger car calls while responding to hall calls, and repeatedly stops running. If there are no calls, the car stops at the last car stop floor or the scheduled waiting floor and waits.

Next, when an abnormality occurs in the hall call registration system, backup control will be described here when the power of the hall call registration system goes down and hall call registration becomes impossible. When the call power signal S1 goes down and hall call registration is no longer possible, the hall call registration abnormality determination unit 6 immediately determines that the call power goes down based on the call power signal 9, the operation status signal of the hall call registration unit 2, and the hall call registration signal. The abnormality determination signal is output to the backup determination control section 5-3 of the elevator operation control device 5. When this backup determination control section 5-3 receives the abnormality determination signal, the call response control section 5-2
It outputs a signal indicating that the hall call is abnormal, and also gives a backup command to the travel control section 5-2 to stop the car at each floor. At this time, the car call occurrence timer 7-1 of the car call occurrence tendency determination device 7 is reset and operated by the abnormality determination signal S2 from the hall call registration abnormality determination unit 6, and the operation of the car call occurrence timer 7-1 is The car call occurrence detection section 7-2 detects the car call registration signal inputted from the car call registration section 4, and also the occurrence average time calculation section 7-2.
3, the average time of the car call occurrence interval is calculated based on the detection signal from the car call occurrence detection section 7-2, and this is used as the car call occurrence frequency to be used as the backup control determination section 5-3 of the elevator operation control device 5. Output to. Then, the backup control determining section 5-3 determines whether this car call occurrence frequency is higher or lower than a predetermined value. The control unit 5-2 continues to issue a break-up command to stop the car at each floor, and when it is determined that the car is low, it issues a break-up command to the travel control unit 5-2 to cancel the backup command described above and respond to the car call.

Therefore, if the frequency of car calls is low, the elevator car will respond preferentially to the car call registered at that time, making it possible to carry passengers to the destination floor without stopping the car on an unnecessary floor. .

This makes it possible to provide efficient service without causing discomfort to passengers.

On the other hand, when the elevator finishes answering the car call and all car registrations are gone, the car call signal from the call response control section 5-1 is turned off, so the backup determination control section 5-3 returns to the travel control section 5-2. A command is issued to stop at each floor, and the elevator begins operating under this backup control.

On the other hand, if there are many passengers (the frequency of occurrence of car calls is high), the backup control determination unit 5-3 holds a backup command to stop at each floor regardless of the presence or absence of car calls.

Therefore, the elevator car can stop at each floor to pick up passengers waiting at the landing, and continue service while disembarking the passengers in the car, so it is possible to provide fair service to passengers on all floors. .

In addition, in the above embodiment, the elevator car was stopped at each floor as a backup control when the frequency of car calls is high, but in the elevator group management system, for example, the elevators are divided into two groups, and one of the elevator cars is divided into two groups, and one of the elevator cars is divided into odd-numbered floors, The same effect as described above can be obtained even if a skip operation method in which the other one is stopped at each even-numbered floor is used as backup control. Further, in the above embodiment, a case has been described in which the power supply goes down as a result of an abnormality in the hall call registration system, but it goes without saying that the same backup control as described above is performed in the event of an abnormality in the hall call registration system due to other factors.

[Effects of the Invention] As described above, according to the present invention, when an abnormality in the hall call registration system is detected, the car call frequency is detected, and when the car call frequency is low, the original backup function is activated. Since car calls are given priority over stopping cars at each floor or skipping, the passengers in the car can be efficiently transported to the destination floor, and the service can be delivered without causing discomfort to the passengers. It is possible to provide 191,118 elevator locations that can improve performance.
