Description

  The present invention relates to an elevator control device that learns the usage state of an elevator for each time zone and controls the operation of the elevator according to the usage status.

  Generally, an elevator door starts a door closing operation after a predetermined door opening time elapses from the end of the door opening operation. The door opening / closing operation is performed at a predetermined door opening / closing speed. The elevator travel is accelerated by a predetermined acceleration to reach the maximum speed, and decelerated by a predetermined deceleration to stop. These door opening time, door opening / closing speed, traveling acceleration, Since deceleration affects passenger transportation efficiency, it must be set to an appropriate value for the elevator usage.

The usage status of elevators often varies depending on the time of day. For example, the time zone used frequently by commuters, the time zone used frequently by commuters, the time zone used frequently by seniors, and the like can be considered. The passenger transportation efficiency can be improved by speeding up the door opening / closing operation by shortening the door opening time setting or increasing the door opening / closing speed. However, when an elderly person or a small child uses the door, if the door opens and closes quickly, there is a possibility of being caught by a closing door or hitting the door, leading to an accident. Therefore, conventionally, a method has been proposed in which the door opening time period is changed to an appropriate value depending on the usage status of each elevator time zone (see Patent Document 1).
JP 05-338970 A

  The above-mentioned proposal has a problem that the door opening / closing speed cannot be changed, and in the case of an elevator with a fast door opening / closing speed, there is a risk that an elderly person or a small child may hit the closing door. In addition, when the elderly travels with normal elevator acceleration and deceleration, there is also a problem that the elderly feel uncomfortable during acceleration and deceleration.

  An object of the present invention is to provide an elevator control device that optimally performs door opening / closing control and elevator travel control in accordance with the use situation of an elevator.

  The purpose of the elevator control device is to measure the average value of the door opening time when the passenger gets on and off, the number of times the elevator is started, the number of operations of the door open extension button, and the number of safety shoe operations, A usage status data table for registering the values measured by the measuring means for each time zone and each floor, a search process for searching for a corresponding value in the usage status data table from the current elevator status, and the search processing The optimum value calculation means for calculating the optimal door opening time, door opening / closing speed, acceleration during driving, and deceleration from the extracted values, and the door opening time, door opening speed, acceleration and deceleration calculated by the optimum value calculating means. This can be achieved by providing a rewriting means for rewriting.

  Because of this configuration, each value measured by the measuring means is always registered in the usage status data table and rewritten learning, and depending on the usage status of the elevator, the door opening time, door opening / closing speed, travel It is possible to optimally set the acceleration and deceleration at the time, and while improving the driving efficiency of the elevator, it is possible to reduce the accident at the time of opening and closing the door and to run with priority on the riding comfort according to the user.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. 1, 2, 3, 4, 5, and 6 are block diagrams showing the configuration of the elevator control device according to the embodiment of the present invention, respectively, and FIG. 7 is an explanatory diagram showing a flowchart showing the operation. is there.

  In FIG. 1, 1 is an elevator car, 2 is a door of the car 1, 3 is an elevator control device, the elevator control device 3 has 4 interfaces, 5 ROMs, 6 CPUs, 7 It is composed of RAM. Reference numeral 8 in FIG. 2 denotes a driving panel provided in the car 1. The driving panel 8 includes an opening button 9 for opening the door, a closing button 10 for closing the door, a car call button 11 for determining the destination of the car, and a door. Is provided with an open extension button 12 for opening for a long time. FIG. 3 shows an UP call button 13 and a DN call button 14 for calling the car 1 installed at the landing on each floor. The UP call button 13 and the DN call button 14 installed on the car 1 and each floor are connected to the CPU 6 through the interface 4 to input signals indicating the operation state of the door 2, the open button 9, and the close button 10. The call button 11, the extension extension button 12, the UP call button 13, and the DN call button 14 are input. In addition, an opening command and a closing command are output to the door 2 via the interface 4 to perform the door opening / closing operation. Reference numeral 15 in FIG. 4 denotes a control setting table that stores setting values for door opening / closing control and acceleration / deceleration control during traveling. The elevator performs door opening / closing operation and traveling control in accordance with the setting values.

  Reference numeral 16 in FIG. 5 is a control setting initial value table that registers initial values of door opening / closing control setting values and acceleration / deceleration control setting values during travel. Reference numeral 17 in FIG. 6 is a usage status data table for recording the usage status of the elevator. The measured values of the door opening time, the number of times the elevator is activated, the number of times of opening and closing the button, and the number of safety shoes are counted for each floor and each time zone. The elevator control device 3 always measures the door opening time, the number of times of starting the elevator, the number of times of opening / extending button operation, and the number of times of safety shoe operation. Processing to update.

  FIG. 7 is a flowchart of a process for changing the door opening / closing time, the door opening / closing speed, the acceleration during the traveling of the elevator, and the deceleration according to the use situation. The door opening command is monitored (S1). If there is a door opening command, the process proceeds to S2, and the current time is read (S2). Next, the floor where the current car 1 is located is calculated (S3). The corresponding usage status data table 17 is searched from the current time and the floor position of the car 1 (S4). The average door opening time, the number of activations, the number of safety shoe operations, and the number of door opening extension button operations are read from the retrieved usage status data table 17 (S5). The door opening average time read in step S5 is set to the door opening time limit of the control setting table 15 (S6). As a result, the time during which the door is open can be set to a time limit that actually matches the usage situation. Next, in step S7, the door opening time limit initial value is read from the control setting initial value table 16 (S7). In step S8, the door opening average time is compared with the door opening average time read in S5, and the door opening time limit initial value is set. If it is shorter, it is considered that the passenger is often in a hurry. Therefore, the process proceeds to step S13, and the door opening / closing speed of the control setting table 15, the acceleration during deceleration, and the deceleration are set as standard (S13). As a result of the comparison in step S8, if the door opening / closing time is longer than the initial value of the door opening time limit, it may be considered that the passenger needs time to get on and off. If, for example, the number of movements exceeds 10%, it is considered that the elderly are often used. Therefore, the process proceeds to step S10, and the door of the control setting table is used to prevent a door accident. The opening and closing speed of the vehicle is set to a slow setting, and the acceleration and deceleration during the traveling of the elevator are set to a low setting to improve the riding comfort during the traveling (S10). If it is determined in step S9 that the operation of the open extension button is less than 10% of the number of activations, the process proceeds to step S11 (S9). In step S11, the ratio of the number of safety shoe operations to the number of activations is calculated. For example, if the number of operations exceeds 10%, it is considered that a small child is often used. In order to prevent this, the door opening / closing speed of the control setting table 15 is set to a slow setting, and the acceleration and deceleration during elevator travel are set to the standard settings (S12). When the setting of the control setting table 15 is completed, the process proceeds to step S14 to perform the door opening / closing operation.

  As described above, the elevator usage status is always recorded in a learning manner for each time zone, and when using the elevator, the elevator operates automatically by changing the door open / close control and travel control according to the recorded contents. Therefore, passengers can transport safely and efficiently in accordance with the actual usage situation of the elevator.
