Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an elevator control device, and in particular to an elevator control device c that automatically determines and controls the floors to be stopped on the way from a departure floor to a destination floor. This is related to this.

[Conventional technology]

Elevators L, 1, A, installed in high-rise residential buildings, etc., are switched to forced stop operation control for each floor because the elevators are in close contact with each other late at night when there are fewer users.

FIG. 6 is a small flowchart of the conventional forced stop operation control for each floor. Judgment is N.

By returning, he prepares for the next start. If the vehicle is running, the determination in step S1 is YES, so the process moves to step S2. In step S2, it is determined whether or not the external instruction indicates a forced operation for each floor. In this case, that is, in the case of a forced stop operation for each floor, the process moves to step S1. Step S
In step 3, it is determined whether there is a car call or not, and if there is no car call, the process moves to step S4 and a stop decision is made to stop the cars on all floors.

Next, if the determination in step S2 is No and if the determination in step S3 is YES, the process moves to step S5 to determine whether or not the floor of the call should be answered. If the result is No, the process returns; if the result is Yes, the process moves to step S4, where a stop decision is made and the car is stopped at that floor.

[Problem that the invention seeks to solve]

As explained above, conventional elevator forced stop control for each floor always stops at all floors from the departure floor to the destination floor, resulting in a significant loss of promptness, resulting in a decline in service and the loss of passenger comfort. There were some frustrating issues.

This invention was made to solve the above-mentioned problems, and provides an elevator control device that can provide the same crime prevention effect as conventional elevators without having to forcefully stop at every floor from the departure floor to the destination floor. The purpose is to provide.

[Means for solving problems]

In the elevator security operation mode, the elevator control device according to the present invention automatically determines intermediate stopping floors according to the number of floors from the departure floor to the destination floor where the car call is registered, The vehicle is forcibly stopped only at this determined floor while moving to the destination floor. Further, in this invention, when an abnormality in the car is detected, the operation is switched to a forced stop operation for each floor.

[For production]

The elevator control device according to the present invention calculates the number of floors between the departure floor and the destination floor where the car call is registered, and, depending on the number of floors, determines the floor at which the car will forcibly stop on the way until the car reaches the destination floor. Since it is automatically determined and stopped, it speeds up movement to the destination floor and prevents the crime prevention effect from deteriorating.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram for explaining an elevator control device according to the present invention. In the figure, 1 is an external switch for instructing a security operation mode provided outside a control room, for example, and 2 is an external switch for instructing a security operation mode. A crime prevention operation start command means for instructing the start of crime prevention operation by being activated by an instruction from a switch 1; 3 is an elevator car that is moved up and down by a hoisting mechanism 4; an operation panel 5 is provided inside the elevator car; It is being

Note that 6 is a destination button provided on the operation panel 5. 7
is a floor number detection means, which is activated by instructions from the crime prevention operation start command means 2 and determines the destination floor from the current stop floor as the departure floor and the output of the operation destination button 6 on the operation panel 5;
The number of floors between the departure floor and destination floor is calculated and output from the relationship between the two. Reference numeral 8 is an intermediate stop floor specifying means, which specifies a forced stop floor on the way that can speed up the movement to the destination floor without reducing the crime prevention effect, according to the number of floors given from the floor number detection means. do. For example, if the number of floors is 10 or more, a forced stop floor is set every 3rd floor, and if the number of floors is 5 or more but less than 10, a forced stop floor is set every 2nd floor or every 3rd floor. is less than 5, a forced stop floor is set for each floor skipped.

Reference numeral 9 denotes a car control means, which controls the drive motor 10 that drives the hoisting mechanism 4 in accordance with instructions from the intermediate stop floor specifying means. These security operation start command means 2, floor number detection means 7, intermediate stop floor identification means 8, and car control means 9 are executed by software processing in the control section 1) that controls the entire elevator shown in FIG. has been done.

FIG. 3 is a block diagram showing an example of the control section 1) shown in FIG. 2, and 12 is a microcomputer. The microcomputer 12 includes a central processing unit (CPU) 13. Memory 141
15 and an output circuit 16. 17 is an external human power device that supplies external human power to the input circuit 15, and 18 is an elevator drive control device that controls the electric drive [9] according to instructions from the output circuit 16.

The operation will be explained below using the flowchart shown in FIG. First, when the microcomputer 12 is driven, it moves to step SIO shown in FIG. 4 and determines whether there is a car call. If the determination at step 310 is No, the process returns. Also, step S
If the determination of IO is YES, the process moves to step Sll and it is determined whether or not there is a calculated flag. Here, the determination in step Sll is YES when the calculation described later is performed for the car call detected in step SIO.
If the calculation described later has not been performed, the result is NO. If the calculated flag exists, the process moves to step S22 to determine whether a new car call has occurred, and if No, the process moves to step S12 to determine the current car position. After storing this in the departure floor F, the process moves to step S13. In step S13,
The nearest forward car call floor from the car position is also stored in the destination floor S, and the process moves to step S14.

Next, in step 314, it is determined whether the destination floor S is above or below the car, and if it is above, the process moves to step S15 and the floor difference H is calculated by H=S-F. If it is below, the process moves to step S16 and the floor difference H is determined by H=F-3. The floor difference H obtained in this way is determined in step 317, and H≧1
If it is 0, the process moves to step 318 and the number of floors J is set to J=3, and if 5≦H<10, the process moves to step S19 and J=2 is set. -1 is set. Next, in step S21, step 318
- The stopping floor is determined according to the value J obtained in S20. In other words, if the floor difference is 10 floors or more, the train will stop every third floor from the departure floor, if the difference is 5 floors or more and less than 10 floors, it will stop every second floor, and if the difference is less than 5 floors, it will stop at every third floor from the departure floor. It stops every other floor and travels to the destination floor.

Next, in step S22, it is determined whether or not a new car call has occurred, and if the determination result is YES, the process moves to step 325, and after resetting the calculated flag, the process returns to step S12 again. If the determination result is NO, the process moves to step 5S23 and it is determined whether or not the destination floor has been reached. Here, if the determination result in step S23 is YES, the calculation completed flag is reset in step S25, and then the return is made.
If the determination result is NO, the process returns after resetting the calculated flag in step S24.

This prepares to re-determine the stopping floor when a new car call is registered, and to immediately start executing calculations when the next new car call is registered once the destination floor has been reached. It's for a reason.

FIG. 5 is a block diagram for explaining another embodiment of the elevator control device according to the present invention, and the same parts as in FIG. 1 are indicated using the same symbols.

In the same figure, 19 is a sensor for detecting an abnormality installed inside the elevator car 3, such as a sensor for detecting metal such as a knife, a sensor for detecting a scream using a gun diode, or an abnormal vibration caused by a passenger flapping. A detection sensor is used. Reference numeral 20 indicates an abnormality detection means for determining an abnormal state by receiving a signal from the sensor 19. Reference numeral 21 is activated by the abnormality detection output of the abnormality detection means 20, and sends a command to forcefully stop all the cars 3 to each floor. Forced stop command means for each floor to be supplied to the control means 9;
22 is a 24-hour timer for automatically instructing the security driving mode.

In such a configuration, when a vibration sensor is used as the sensor 19, vibrations within the car 3 are detected and supplied to the abnormality detection means 20. The abnormality detection means 20 is the sensor 19
Anomalies within the car are detected by identifying the output signals of the car. That is, when a passenger flaps around due to the occurrence of an abnormal condition, the car 3 vibrates abnormally, and the sensor 19 detects and outputs this abnormal vibration. Since the output signal of the sensor 19 abnormally changes in a range exceeding a set value, the abnormality detection means 20 determines this state and identifies that an abnormality has occurred in the car. When the abnormality detection means 20 identifies the occurrence of an abnormality, it generates an output signal and supplies it to the forced stop command means 21 on each floor.

When receiving a signal from the abnormality detection means 20, the each floor forced stop command means 21 supplies a command to the car control means 9 to forcibly stop the car 3 on all floors up to the destination floor. When the car control means 9 receives a command from each floor forced stop command 21, it gives priority to the command from the intermediate stop floor specifying means 8 and applies control for forced stop to each floor to the drive motor 10. As a result, when an abnormality occurs in the elevator car 3, the operation is switched to a crime prevention operation that temporarily stops all floors, thereby ensuring the safety of passengers. Further, by using the 24-hour timer 22 for the external switch 1, it becomes possible to automatically switch to the security mode within a preset time range. Furthermore, depending on the frequency of call occurrences per unit time, the system may automatically switch to crime prevention mode when the number of users is extremely low.

In the above embodiment, a case has been described in which the number of floors to be skipped J is set, but instead of J, one running time is set, and after running for this running time, a stop decision is made, Or, for the time being, increase the number of floors up to the stop floor (for example, 3
It is also possible to calculate the number of skipped floors by dividing the number of floors equally.

〔Effect of the invention〕

As explained above, according to the present invention, during crime prevention driving, the stopping floor on the way is automatically determined according to the number of floors from the departure floor to the destination floor, and the stop is forced only at this determined floor. As a result, the number of stops along the way is reduced, and the travel time to the destination floor is shortened.As a result, the service is improved without reducing the crime prevention effect, so the number of stops on the way is reduced. It has the effect of alleviating irritation.
