Description

  The present invention is a relief operation function effective at the time of emergency operation stop such as when a disaster or trouble occurs, and has a function of evacuating the elevator to another floor when the elevator cannot be opened when landing on the service floor. The present invention relates to an elevator control device.

  Conventionally, in an elevator mechanism, a door opening command is output when a car that moves up and down arrives at a service floor. At that time, an inner door (also called a car door or hatch door) in the car and an outer door provided on each floor If the door cannot be opened, the car will not be able to move from that floor and will be unable to drive. In order to solve these problems, in the elevator control system, when the car stops in response to the car call, if the doors on the floor (inner door and outer door) do not open after a certain period of time, It has a function to carry out another floor retreat operation to move to another floor.

  As a well-known technique related to the other floor evacuation operation of the elevator control device, for example, in a group management elevator, the floor of a poorly opened door and the car number of the car are stored in advance, and the car of the other car is Corresponding “elevator operation device” (see Patent Document 1), “the elevator door control device” that counts the number of operations of the overload detection device and evacuates the car to the nearest floor when a certain number of times have elapsed. (Refer to Patent Document 2), “Elevator Operation Control Device” for driving a car to another floor based on an artificial call equivalent to a call whose destination is an arbitrary floor that disappears after the car is started (see Patent Document 3) ), “Elevator driving device” (see Patent Document 4) that automatically registers the car call of the stoppable floor closest to the poorly opened door.

  The technologies related to the other floor retreat operation of the elevator control device according to Patent Document 1 to Patent Document 4 described above are functions that can sufficiently prevent a single passenger car from traveling to a floor that cannot be opened. There is a problem that is not held.

  Specifically, in the technology according to Patent Document 1, when a hall call button for a poorly opened floor is pressed in a group management elevator, it is a function that gives priority to a car that is not stored as a poorly opened floor. . However, in the elevator function of a single car, there is no other car in the elevator car. Therefore, when the poorly opened floor is the nearest floor, there is a possibility of landing on the poorly opened floor. .

  In the technique according to Patent Document 2, in the elevator function having a function of detecting that the door cannot be fully opened and reversing the door once and then opening the door again, the count number of the opening / closing reversal operation exceeds a predetermined value. Because other floor evacuation operation is carried out, and the status of the poorly open doors on the other floors is not judged, if the nearest floor is a poorly open door in such technology, go to the poorly open door. There is a possibility of landing.

  In the technology according to Patent Document 3, when it is detected that the door cannot be opened, an artificial call equivalent to a call with an arbitrary floor as a destination is generated and the other floor is evacuated. Therefore, if any floor is a poorly opened floor, there is a possibility of landing on the poorly opened floor.

  In the technology according to Patent Document 4, when a door opening failure is detected and a passenger cannot get off, a car call of a stoppable floor closest to the door opening failure floor is automatically registered and the other floor is evacuated. Since the status of the poorly opened floor on the other floor is not determined, if the stop floor closest to the poorly opened floor is a poorly opened floor even in this technology, it will arrive at the poorly opened floor. There is a possibility of flooring.

  The present invention has been made to solve such problems, and its technical problem is a function that can sufficiently prevent retreat operation to a floor that cannot be opened even for a single car. It is in providing the elevator control apparatus which has.

  In order to solve the technical problem described above, the present invention detects the state in which the inner door of the car and the outer door provided on each floor cannot be opened during landing when the elevator is lifted to the floor. In the elevator control device equipped with the non-openable floor detecting means, the storage means for storing the floor information that cannot be opened by the non-openable floor detecting means, and the landing floor at the time of the elevator operation with respect to the car When it is detected that the door cannot be opened by the unopenable floor detecting means, if there is another floor that cannot be opened in the past as a result of referring to the floor information stored in the storage means, And another floor evacuation operation control means for performing the evacuation operation on the other floors in order from the nearest one close to the stop floor.

  Further, in one embodiment of the elevator control apparatus, the storage means stores, as floor information, the number of floors that cannot be opened by the non-openable floor detection means for each floor, and saves the other floors. The control means, for the floor information, according to the result of establishing and registering the evacuation floor priority by weighting the priority to the evacuation floor based on the number of times for each floor that has become unopenable, The other floor evacuation operation is performed to the other floors corresponding to the order of priority, except for the landing floor where the door unopenable floor is detected by the door unopenable floor detection means.

  Furthermore, another embodiment of the elevator control apparatus is characterized in that the establishment of the evacuation priority by the other floor evacuation operation control means is performed for each driving direction with respect to the car.

  In addition, in another embodiment of any of the above elevator control devices, the other floor evacuation operation control means has no other floor that cannot be opened when the evacuation floor priority is established, and the door cannot be opened on all floors. If it is determined that the vehicle has reached, it is determined that there is an abnormality in the inner door of the car, the operation is stopped, and the outside is automatically notified to the outside.

  On the other hand, in another embodiment of any one of the above elevator control devices, when a car call is made for an arbitrary floor in the car and the car call registration is performed, the car called floor is registered. If the floor information of the floor corresponds to a lower priority floor, the car door state is announced in advance by means of voice guide voice means attached to the car, and then the car call is made according to the car call again. It is characterized by registration.

  On the other hand, in another embodiment of any one of the above elevator control devices, when hall call registration is performed by making a hall call on an arbitrary floor, priority is given to the floor information in which the hall called floor is registered. If it corresponds to a low floor, the announcement of the state of the car door in advance by voice guide voice means attached to each floor, and then the car call registration is performed in response to the hall call again .

  According to the elevator control device of the present invention, when the door cannot be opened at the time of landing, the result of accumulating and storing the floor information indicating that the door cannot be opened in the past is referred to for other floors that cannot be opened. Since the other floors are evacuated in order of priority from the nearest one, even an elevator mechanism of a single car can suppress landing on a poorly opened door due to the other floor evacuation operation as much as possible. In addition, for floor information, evacuation floor priorities are established and registered by weighting priority to evacuation floors based on the number of times for each floor that cannot be opened. Because other floors are evacuated in descending order of priority based on floor information, landing is performed in the order of the possibility of opening the door, which is effective when an emergency operation is stopped in the event of a disaster or trouble. Relief measures driving function is established. In addition, when it is determined that there are no other floors that cannot be opened when the evacuation floor priority is established, and the inability to open all the floors, the operation is suspended even if there are no elevator users. Since it is regarded as a door abnormality and automatically issued to the outside of a maintenance company or the like, maintenance and management measures can be taken in advance to prevent users from being trapped in the car.

  Below, the elevator control apparatus of this invention is demonstrated in detail with reference to drawings.

  FIG. 1 is a block diagram illustrating a schematic configuration of an entire elevator mechanism including an elevator control device 3 according to a first embodiment of the present invention.

  In this elevator mechanism, the operation command control signal from the elevator control device 3 is received, the main rope is frictionally driven through the sheave by the power of the motor provided in the hoisting machine 11, and the riding in a state where the main rope is suspended from the main rope. The car 1 is raised and lowered.

  The car 1 is provided with an in-car speaker 13 and a car call button 12. On the facility side where the car 1 moves up and down, a hall button 14 and a hall speaker 15 for voice guidance are installed for each floor. Moreover, when landing at the time of elevator operation to the target floor of the elevator, the inner door (car door, hatch door) of the car 1 detected by the door-open state floor detection unit 2 and the outer door provided on each floor The detection result of the door open state is transmitted to the elevator control device 3. In addition, the door open state detection part 2 here detects the door open state of an internal / external door in cooperation with the sensor part provided for every floor, and the sensor part provided in the car 1. FIG.

  The elevator control device 3 detects an operation direction detection unit 8 that detects a direction (elevator service direction) when the car 1 is in an up / down operation, and a stop that detects a stop floor (landing floor) when the car 1 is in an up / down operation. The floor detection unit 7, the door opening impossible floor detection unit 4 for detecting the door opening impossible state for each floor from the detection result of the inside / outside door state detected by the door opening state detection unit 2, and the door opening impossible floor detection unit 4 are doors The unopenable number storage device 5 that counts the number of times the door cannot be opened at the stop floor when the unopenable state is detected and accumulates and stores it as floor information, and the floor that has become unopenable in the past with respect to the floor information. The evacuation floor priority establishment unit 6 for establishing the evacuation floor priority by weighting the evacuation floor priority based on the number of times, and the evacuation floor for registering the floor information for which the evacuation floor priority is established There is an abnormality in the inner door of the registration unit 9 and the car 1 A notification unit 10 to automatically alarm when it is determined shutdown outside, and a.

  Among these, the door opening impossible count storage device 5, the evacuation floor priority establishment unit 6, the evacuation floor registration unit 9, and the notification unit 10 are provided as functions in the other floor evacuation operation control unit 16. The other-floor evacuation operation control unit 16 performs the functions of these units, and when the door-opening impossible floor detection unit 4 detects that the door cannot be opened on the landing floor during the lifting operation with respect to the car 1, the number of times the door cannot be opened. As a result of referring to the floor information read out from the storage device 5, if there is another floor that has not been opened in the past, the other floor evacuation operation is performed with priority from the nearest one of the other floors.

  Further, the other floor evacuation operation control unit 16 evacuates the floor information stored in the door opening impossibility count storage device 5 by the evacuation floor priority establishment unit 6 based on the number of times for each floor that cannot be opened. The floor information as a result of establishing the evacuation floor priority by weighting the priority to the floor is registered in the evacuation floor registration unit 9. Thereby, according to the registered floor information, the other floor evacuation operation is performed to the other floors corresponding to the order of priority, except for the landing floor where the door unopenable floor detection unit 4 has detected that the door cannot be opened. Implement automatically. Note that when the evacuation priority is established by the evacuation floor priority establishment unit 6, since the information on the operation direction is obtained from the operation direction detection unit 8, the evacuation floor registration unit 9 indicates the floor indicating the evacuation floor priority. Information is registered according to the driving direction for the car 1.

  Further, when the other floor evacuation operation control unit 16 determines that there is no other floor that cannot be opened when the evacuation floor priority is established, and that the door cannot be opened extends to all the floors, It is determined that there is an abnormality, the operation is stopped, and the notification unit 10 automatically issues a notification to the outside.

  That is, in the elevator control device 3 according to the first embodiment, the other floor retreat operation control unit 16 stores the unopenable number of times for each floor in the unopenable number storage device 5 and retreats according to the unopenable number of times. The floor priority establishment unit 6 weights the priority indicating the unsuccessful door opening status to the evacuation floor, and registers floor information indicating the evacuation floor priority in the evacuation floor registration unit 9, so that the landing of the car 1 Sometimes when the door cannot be opened is detected by the non-openable floor detection unit 4, if there is another floor that cannot be opened in the past as a result of referring to the floor information, it is closest to the stop floor (landing floor). The other floor evacuation operation can be carried out in order of priority. Thereby, even if it is an elevator mechanism of a single passenger car, it is possible to suppress landing on a poorly opened floor due to another floor retreat operation as much as possible.

  In addition, for floor information, the priority of the evacuation floor is weighted based on the number of times for each floor that cannot be opened, and the evacuation floor priority is established and registered. Accordingly, since the other floor evacuation operation is performed, landing is performed in descending order of the possibility of opening (priority), which is effective when the rescue operation is continuously performed. Therefore, the other floor evacuation operation control unit 16 has a function of creating a car call of the floor having the lowest weight of the door opening failure situation.

  Further, when the other floor evacuation operation control unit 16 determines that there is no other floor that cannot be opened when the evacuation floor priority is established, and that the door cannot be opened extends to all floors, the inner door of the car 1 It judges that it is abnormal, stops the operation of the elevator, and automatically notifies the maintenance company or the like outside by the notification unit 10. As a result, the maintenance / inspection promotion function works effectively in addition to the rescue operation function when emergency operation is stopped in the event of a disaster or trouble, and maintenance / management to prevent users from being trapped in the car 1 Measures can be taken in advance. Incidentally, the biggest cause of the inability to open the inner and outer doors in the elevator mechanism is more than that caused by the aging of the entire mechanism part, and the sensor unit and the car 1 provided for each floor in the door open state detection unit 2. Since there are many cases where the installation position relationship with the sensor unit provided in the vehicle is caused by a problem of misdetection due to misalignment, it is effective in maintaining and managing the elevator mechanism.

  FIG. 2 is a flowchart illustrating the operation process of the other floor retreat operation related to the entire elevator control device 3.

  In the operation processing of the other floor evacuation operation related to the entire elevator control device 3, first, the door open state detection unit 2 performs the door open state detection unit 2 under the condition in which the elevator control device 3 outputs a door open command (step S <b> 21) after the landing of the car 1. It is assumed that the door cannot be opened for X seconds (step S22).

  In this case, the other floor evacuation operation control unit 16 stores the number of unopenable floors detected by the unopenable floor detection unit 4 of the elevator controller 3 in the unopenable number storage device 5 for each floor as floor information. By storing, the evacuation floor priority establishment unit 6 establishes the evacuation floor priority by weighting the priority to the evacuation floor based on the number of times for each floor that cannot be opened in the floor information. The priority setting of the floor that cannot be opened is performed (step S23). The floor information for which the evacuation floor priority is established is registered in the evacuation floor registration unit 9. Note that the floor information here includes information about the number of floors that cannot be opened, as well as the number of floors that cannot be opened. It is.

  Therefore, the elevator control device 3 performs call setting (step S24) of the evacuation floor based on the evacuation floor priority of the floor information registered in the evacuation floor registration section 9 by the other floor evacuation operation control section 16. A drive control signal is given to the motor of the machine 11, thereby starting the operation of the car 1 to the retreat floor (step S25), and the processing operation is ended.

  FIG. 3 is a flowchart showing an example of operation processing of the other floor retreat operation related to the other floor retreat operation control unit 16 provided in the elevator control device 3.

  In the operation processing of the other floor evacuation operation related to the other floor evacuation operation control unit 16, when the door unimpossible floor detection unit 4 detects the door unimpossible floor setting, the unopenable floor setting (step S <b> 31) is performed. Subsequently, it is shown that the number of times the door cannot be opened for each floor is stored in the door opening impossible number storage device 5 as the setting of the number of times the door cannot be opened (step S32). After that, as another floor evacuation priority setting (step S33) according to the number of times the door cannot be opened (step S33), the evacuation floor priority establishing unit 6 is assigned to the evacuation floor based on the number of times for each floor that cannot be opened. Priority level weighting is performed to establish the evacuation floor priority and register it in the evacuation floor registration unit 9, and the processing operation ends.

  FIG. 4 is a flowchart illustrating another example of the operation process of the other floor retreat operation related to the other floor retreat operation control unit 16 provided in the elevator control device 3.

  In the operation processing of the other floor evacuation operation related to the other floor evacuation operation control unit 16 here, first, the stop floor detected by the stop floor detection unit 7 at the time of the above-described evacuation floor call setting (step S24), After the process of removing the stop floor from the evacuation floor that excludes the landing floor detected by the door unavailability floor detection section 4 from the evacuation floor candidates (step S41), the floor is registered in the evacuation floor registration section 9. The floor information closest to the stop floor (landing floor) is prioritized and searched from the floor information (step S42), and the retreat floor with higher priority is prioritized (step S43) and retrieved. At this time, since the driving direction for the raising / lowering of the car 1 is detected from the driving direction detection unit 8, the driving direction is detected when a plurality of floors closest to the stop floor (landing floor) are searched. Is given priority (step S44), and the other floor evacuation operation is performed.

  FIG. 5 is a schematic view illustrating an operation transition state for explaining a specific example of the operation process of the other floor evacuation operation related to the other floor evacuation operation control unit 16.

  In the operation transition of the other floor evacuation operation, when the elevator car 1 is initially landed on the first floor (1FL) (step S51), the unopenable floor detection unit 4 detects that the door cannot be opened (determination). ), The number of times the first floor cannot be opened is changed from 0 to one (step S52), and the priority is changed from 1 to 2 by comparing with the number of times the other floor cannot be opened (step S52). Step S52) is performed. At this time, the priority of the other floor is also changed, and for example, the priority of the second floor (2FL) is changed from 2 to 3 (step S53).

  Also, the first floor (1FL), which is the stop floor (landing floor) of the elevator, is excluded from the evacuation floor, the third floor that has the highest priority over the second floor (2FL) that is closest to other floors. The state where the other floor retreat operation (step S54) is performed to (3FL) is shown.

  In addition, there is no car call in the car 1 other than the first floor (1FL) where the door cannot be opened, and a new car call (hall call) is on the 4th floor (4FL). When the target is created (step S56), the second floor evacuation permission for the second floor (4FL) and the second floor evacuation operation (step S54) for the third floor (3FL) are permitted (step S54). The priority with S55) is compared, and the other floor evacuation operation service is performed to the floor with higher priority. By the way, since both the 3rd floor (3FL) and the 4th floor (4FL) are the same with priority 1, the car 1 is automatically landed on the 3rd floor (3FL). If the priority of the fourth floor (4FL) is higher than the third floor (3FL), the car 1 is automatically landed on the fourth floor (4FL).

  FIG. 6 is a flowchart showing the operation process of the additional function for the other floor evacuation operation related to the other floor evacuation operation control unit 16.

  In the additional function for the other floor evacuation operation related to the other floor evacuation operation control unit 16, there is no other floor that cannot be opened when the evacuation floor priority is established by the other floor evacuation priority establishment unit 6, and the door cannot be opened. If it is determined that the floor has reached all the floors, the process of determining the unopenable history of all floors (step S61) is performed, the elevator operation is suspended (step S62), and the notification unit 10 automatically issues it to the maintenance company. The process of reporting (step S63) is performed.

  FIG. 7 is a flowchart showing an operation process of another additional function for the other floor retreat operation related to the other floor retreat operation control unit 16 of the elevator control device 3.

  An additional function of the elevator control device 3 is that priority is given to the floor information registered in the evacuation floor registration unit 9 when the evacuation floor priority establishment unit 6 establishes the evacuation floor priority in the other floor evacuation operation control unit 16. When the weight for the degree is lower than the predetermined threshold, it is possible to predict the situation where the door cannot be opened during the service of other floor evacuation operation, so if the target floor corresponds to a floor with low priority, This is a service function that is implemented when registering.

  More specifically, priority is given by making a car call by pressing the car call button 12 corresponding to a floor with a low priority for the registered floor information or by making a hall call by pressing the hall call button 14. When call detection of a low floor (step S71) is performed, the door state of the call floor (registered floor) is detected by the car speaker 13 attached to the car 1 or the hall speaker 15 installed on each floor. Is announced in advance (step S72). Thereafter, when there is a car call or a hall call again, after making the call again (step S73), call registration (step S74) is performed, and the operation process is terminated.

  That is, here, as a function added to the elevator control device 3, when a car call is made by depressing the car call button 12 for any floor in the car 1, the car call is registered. If the floor corresponds to a floor with low priority for the registered floor information, after the car door state is announced in advance by the car speaker 13 as a voice guide utterance means attached to the car 1 When a hall call is registered by making a hall call by pressing the hall call button 14 on any floor and registering a hall call in response to another car call, the floor called the hall is registered. If the floor information corresponds to a floor with low priority, the state of the car door is announced in advance by the hall speaker 15 which is a voice guide utterance means attached to each floor. After the same as those described are collectively, and function for the car call registration in accordance with the hall call again.
