With such a control, the door 110 can be quickly closed while securing the safety of the passengers.

Description

The present invention relates to an elevator system.
More specifically, the present invention relates to an elevator system that realizes door closing control faster than before while ensuring safety.

  For example, in the case of a high-rise building where a company occupies, an elevator is required to operate quickly for passengers. Especially in the morning hours, many elevator passengers rush to work in the office. In such a case, the passenger presses a close button provided on the operation panel in the elevator and performs an instruction operation to close the door earlier than the normal operation state.

On the other hand, elevators must absolutely keep passengers safe. For this reason, the door is provided with a door sensor for detecting the passage of passengers. The door sensor is a kind of a general photo interrupter that includes a combination of a light emitting element such as an infrared LED and a light receiving element such as a phototransistor. When the door sensor detects a passenger passing through the door, the elevator control device that controls the door opens the door immediately if the door is being closed, and if the door is fully open, In addition, the door is opened for a certain period of time after no passengers are detected.
A prior art document that seems to be similar to the present invention is shown in Patent Document 1.

Japanese Unexamined Patent Publication No. 7-117959

  Some passengers consider other passengers still in the elevator car when getting out of the elevator, so that the door can be quickly closed by pressing the close button and getting off. However, when the door sensor detects the passage of the passenger, control for closing the door is waited for a preset waiting time after the passenger is no longer detected. In this case, there is no point in pressing the corner closing button.

  This invention is made | formed in view of the situation which concerns, and it aims at providing the elevator system which performs the control which detects the passenger who gets down by pushing a close button correctly, and closes a door rapidly.

In order to solve the above-described problems, an elevator system according to the present invention is provided in a car, a passenger moving on a predetermined stop floor, a door provided on the car, a door motor for opening and closing the door, and the door. A door sensor for detecting the presence of a passenger passing through the door, an entrance sensor for detecting the presence of a person in the vicinity of the door on the stop floor, and a closure provided on the inner side of the car And a switch.
When the door drive control unit detects from the door sensor and the entrance sensor that the passenger has moved between the car and the stop floor in a state where the closing switch is not pressed, the door drive control unit determines the door open state. After controlling the door motor to close the door after maintaining only the time, after detecting that the closing switch was pressed, it was detected from the door sensor and the entrance sensor that the passenger moved between the car and the stop floor. In this case, the door motor is controlled to close the door without maintaining the door open state for a predetermined time.

  The door drive control unit detects that the passenger has pressed the close button and both the door sensor and the entrance sensor detect the passenger immediately after the passenger presses the close button, or when the passenger exits the car while pressing the close button. In response to the disappearance, the door is immediately closed without setting a waiting time. By processing in this way, the door can be quickly closed while ensuring the safety of passengers.

  According to the present invention, it is possible to provide an elevator system that correctly detects a passenger who gets off by pressing a close button and quickly closes the door.

The state where the open button 302 is pressed until it is fully opened is stored.
The door drive flag is a flag indicating whether or not the door 110 is driven to open and close.
The door opening / closing flag is a flag indicating the driving direction of the door 110, that is, whether the door 110 is opened or closed when the door driving flag is logical “true”.

[First Embodiment: Operation]
The flow of the opening / closing control operation of the door 110 in the elevator system 101 according to the first embodiment of the present invention will be described with reference to FIGS. In addition, all the flowcharts demonstrated after this start operation | movement when the car 102 arrives at the arbitrary stop floor 109, and complete | finish operation | movement when the door 110 closes.

FIG. 5 is a flowchart showing an operation flow of the door sensor 201.
When the car 102 arrives at an arbitrary stop floor 109 (S501), the door drive control unit 401 first sets the door sensor flag to a logical “false” (S502).

The rest is a loop.
Next, the door drive control unit 401 confirms whether or not the door sensor 201 has detected the presence of a passenger passing through the door 110 (S503).
If the door sensor 201 detects the presence of a passenger passing through the door 110 (YES in S503), the door drive control unit 401 sets the door sensor flag to logical “true” (S504) and sets the door open / close flag. The logic is set to mean “open door 110” (S505).

On the other hand, if the door sensor 201 does not detect the presence of a person in step S503 (NO in S503), the door drive control unit 401 sets the door sensor flag to logic “false” (S506).
In either case of step S505 and step S506, after these processes, the door drive control unit 401 confirms whether the door closing switch 403 has detected that the door 110 has been closed (S507).
If the door 110 is not closed (NO in S507), the door drive control unit 401 repeats the process from step S503 again.
If the door 110 is closed (YES in S507), the door drive control unit 401 ends the series of processes (S508).

FIG. 6 is a flowchart showing an operation flow of the inlet sensor 202.
When the car 102 arrives at an arbitrary stop floor 109 (S601), the door drive control unit 401 first sets the entrance sensor flag to logical “false” (S602).

The rest is a loop.
Next, the door drive control unit 401 confirms whether or not the entrance sensor 202 has detected the presence of a person (S603).
If the entrance sensor 202 detects the presence of a person (YES in S603), the door drive control unit 401 sets the entrance sensor flag to logic "true" (S604) and sets the door open / close flag to "open the door 110". Is set to a logic meaning "" (S605).

On the other hand, if the entrance sensor 202 has not detected the presence of a person (NO in S603), the door drive control unit 401 sets the entrance sensor flag to logic “false” (S606).
In either case of step S605 and step S606, after these processes, the door drive control unit 401 confirms whether the door closing switch 403 has detected that the door 110 has been closed (S607).
If the door 110 is not closed (NO in S607), the door drive control unit 401 repeats the process from step S603 again.
If the door 110 is closed (YES in S607), the door drive control unit 401 ends the series of processes (S608).

  As can be seen from the above description, the door sensor control of FIG. 5 and the inlet sensor control of FIG.

FIG. 7 is a flowchart showing the flow of the operation of the close button 303.
When the car 102 arrives at an arbitrary stop floor 109 (S701), the door drive control unit 401 first sets the closed button flag to logical “false” (S702).

The rest is a loop.
Next, the door drive control unit 401 confirms whether or not the close button 303 has been pressed (S703).
If the close button 303 is pressed (YES in S703), the door drive control unit 401 sets the close button flag to logical “true” (S704).
If the close button 303 is not pressed (NO in S703), the door drive control unit 401 does not operate the close button flag.

In any case of step S704 and NO in step S703, after these processes, the door drive control unit 401 next checks whether or not the first timer is currently performing a timekeeping operation (S705).
If the first timer is performing the timekeeping operation (YES in S705), the door drive control unit 401 forcibly ends the timekeeping operation (S706).
If the first timer is not performing the timekeeping operation (NO in S705), the door drive control unit 401 does not operate the first timer.

In either case of step S706 and step S705, after these processes, the door drive control unit 401 confirms whether the door closing switch 403 has detected that the door 110 is closed (S707). .
If the door 110 is not closed (NO in S707), the door drive control unit 401 repeats the process from step S703 again.
If the door 110 is closed (YES in S707), the door drive control unit 401 ends the series of processes (S708).

As will be described in detail later, the first timer does not operate the open button 302 and the close button 303 after the car 102 arrives at the stop floor 109 and opens the door 110. In the situation where the presence of a person is not detected, the “predetermined door opening time” is counted when the door 110 is automatically closed. By pressing the close button 303, the door drive control unit 401 forcibly terminates the time counting operation of the first timer, so that it is possible to immediately shift to the operation of closing the door 110.
Further, once the close button 303 is pressed, the close button flag becomes logical “true”, and thereafter the close button flag does not change to logical “false”. That is, the close button flag has a latch function of storing the fact that the close button 303 is pressed.

FIG. 8 is a flowchart showing the flow of the operation of the open button 302.
When the car 102 arrives at an arbitrary stop floor 109 (S801), the door drive control unit 401 first sets the open button flag to logical “false” (S802).

The rest is a loop.
Next, the door drive control unit 401 confirms whether or not the open button 302 has been pressed (S803).
If the open button 302 is pressed (YES in S803), the door drive control unit 401 sets the open button flag to logic “true” and sets the door open / close flag to logic that means “open door 110”. Setting is made (S804).

Next, the door drive control unit 401 confirms whether or not the door opening switch 402 has detected that the door 110 has been fully opened (S805). If the door 110 is not fully opened at this time (NO in S805), the door drive control unit 401 loops until the door 110 is fully opened.
If the door 110 has been fully opened (YES in S805), the door drive control unit 401 next checks whether or not the open button 302 has been pressed (S806).
If the open button 302 is pressed (YES in S806), the door drive control unit 401 loops until the open button 302 is not pressed.
If the open button 302 has not been pressed (NO in S806), the door drive control unit 401 next sets the open button flag to logic “false” (S807), and repeats the processing from step S803 again.

In step S803, if the open button 302 is not pressed (NO in S803), the door drive control unit 401 confirms whether the door close switch 403 detects that the door 110 is closed (S808). .
If the door 110 is not closed (NO in S808), the door drive control unit 401 repeats the process from step S803 again.
If the door 110 is closed (YES in S808), the door drive control unit 401 ends the series of processes (S809).

  The open button 302 maintains the state in which the door 110 is opened only when the door 110 is being pressed when the door 110 is pressed while the door 110 is being closed, and the door 110 is opened. In order to realize this operation, the door drive control unit 401 keeps the open button flag logically “true” until the door 110 is fully opened, and the door open / close flag is also “open the door 110”. And keep that state. That is, the open button flag and the door open / close flag are latched until the door 110 is fully opened (YES in S803 → S804 → NO in S805). When the door 110 is fully opened (YES in S805), the latch is not performed. If the open button 302 is pressed while the door 110 is fully opened, the loop of NO at step S806 → YES at S807 → YES at S803 → YES at S804 → S805 is repeated while the open button 302 is being pressed.

FIG. 9 is a flowchart showing the flow of the door drive flag control operation.
When the car 102 arrives at an arbitrary stop floor 109 (S901), the door drive control unit 401 first sets the door drive flag to logic “true” and sets the door open / close flag to logic that means “open door 110”. Are set respectively (S902).

The rest is a loop.
Next, the door drive control unit 401 confirms whether or not the door drive flag is logical “true” (S903).
If the door drive flag is logical “true” (YES in S903), has the door drive control unit 401 confirmed the door open switch 402 and detected that the door open switch 402 has fully opened the door 110? It is confirmed whether or not (S904). If the door 110 is not fully opened at this time (NO in S904), the door drive control unit 401 confirms whether or not the door close switch 403 detects that the door 110 is closed (S905). ).
If the door 110 is not closed (NO in S905), the door drive control unit 401 repeats the process from step S903 again.
If the door 110 is closed (YES in S905), the door drive control unit 401 ends the series of processes (S906).

  If the door 110 is fully opened at the time of step S904 (YES in S904), the door drive control unit 401 sets the door drive flag to logical “false” (S907) and repeats the processing from step S903.

  The door drive flag control shown in FIG. 9 indicates that if the door drive flag is true (YES in S903) and the door 110 is fully opened (YES in S904), the door drive flag is set to logical “false”. Then, stop driving the door 110 ”.

FIG. 10 is a flowchart showing the flow of the door drive control operation.
When the car 102 arrives at an arbitrary stop floor 109 (S1001), the door drive control unit 401 first checks whether or not the door drive flag is logical “true” (S1002).

If the door drive flag is logical “true” (YES in S1002), the door drive control unit 401 next confirms whether or not the door opening / closing flag is a logic that means “open door 110” ( S1003).
If the door opening / closing flag is logic that means “open door 110” (YES in S1003), the door drive control unit 401 issues a command to open the door 110 to the door motor 111 (S1004). The process is repeated again from step S1002.

In step S1003, if the door open / close flag is logic that means “close door 110” (NO in S1003), the door drive control unit 401 issues a command to the door motor 111 to close the door 110 ( S1005). Then, the door drive control unit 401 confirms whether or not the door closing switch 403 has detected that the door 110 is closed (S1006).
If the door 110 is not closed (NO in S1006), the door drive control unit 401 repeats the process from step S1002 again.
If the door 110 is closed (YES in S1006), the door drive control unit 401 ends the series of processes (S1007).

  If the door drive flag is logical “false” at the time of step S1002 (NO in S1002), the door drive control unit 401 issues a command to stop the drive of the door 110 to the door motor 111 (S1008). ) The process is repeated again from step S1002.

The door drive control shown in FIG. 10 repeats the following three operations.
If the door drive flag is true (YES in S1002) and the door opening / closing flag means “open door 110” (YES in S1003), the door motor 111 is controlled to open the door 110 (S1004).
If the door drive flag is true (YES in S1002) and the door open / close flag means “close door 110” (NO in S1003), the door motor 111 is controlled to close the door 110 (S1005).
If the door drive flag is false (NO in S1002) (NO in S1002), the drive of the door 110 is stopped (S1008).

  Note that the flowcharts described with reference to FIGS. 5 to 10 are common to the second and third embodiments described later.

11 and 12 are flowcharts showing the flow of control operation for closing the door 110.
When the car 102 arrives at an arbitrary stop floor 109 (S1101), the door drive control unit 401 first confirms whether or not the door opening switch 402 detects that the door 110 has been fully opened (S1102). If the door 110 is not fully opened at the time of step S1102 (NO in S1102), the door drive control unit 401 repeats the process of step S1102 again. That is, the door drive control unit 401 waits until the door 110 is fully opened.

If the door 110 is fully opened at the time of step S1102 (YES in S1102), the door drive control unit 401 next starts the first timer (S1102). Then, the door drive control unit 401 confirms whether or not the first timer indicates that a predetermined time has elapsed (S1104).
If the time defined in the first timer has not elapsed at the time of step S1104 (NO in S1104), the door drive control unit 401 repeats the process from step S1104 again. That is, the door drive control unit 401 waits until the first timer times the specified time.

  If the time specified in the first timer has elapsed at the time of step S1104 (YES in S1104), the door drive control unit 401 next sets the door drive flag to logical “true” and the door open / close flag. Are set to logics that mean "close door 110" (S1105).

The description of the flowchart will be continued with reference to FIG.
Next, the door drive control unit 401 confirms whether or not the door sensor flag is logical “false” (S1206).
If the door sensor flag is logical “false” (YES in S1206), the door drive control unit 401 then checks whether the entrance sensor flag is logical “false” (S1207).
If the entrance sensor flag is logical “false” (YES in S1207), the door drive control unit 401 confirms whether or not the door opening / closing flag is a logic meaning “close door 110” (step S1207). S1208).

If the door opening / closing flag is logic that means “close door 110” (YES in S1208), then the door drive control unit 401 determines whether the door closing switch 403 has detected that the door 110 is closed. Is confirmed (S1209).
If the door 110 is not closed (NO in S1209), the door drive control unit 401 repeats the process from step S1206 again.
If the door 110 is closed (YES in S1209), the door drive control unit 401 ends the series of processes (S1210).

In step S1206, if the door sensor flag is logical “true” (NO in S1206), the door drive control unit 401 then sets the door opening / closing flag to logic that means “open door 110” (S1211). ).
Similarly, in step S1207, if the entrance sensor flag is logical “true” (NO in S1207), the door drive control unit 401 then sets the door open / close flag to logic that means “open door 110”. (S1211).

After step S1211, the door drive control unit 401 confirms whether or not the door opening switch 402 has detected that the door 110 has been fully opened (S1212). The process loops until the door 110 is fully opened (NO in S1212).
In step S1208, if the door opening / closing flag is logic that means “open door 110” (NO in S1208), the door drive control unit 401 similarly detects that the door 110 has been fully opened. It is confirmed whether or not it has been done (S1212). And it loops until the door 110 is opened completely (NO of S1211).

After looping until the door 110 is fully opened (YES in S1212), the door drive control unit 401 checks whether the close button flag is logical “true” (S1213).
If the close button flag is logical “true” (YES in S1213), the door drive control unit 401 repeats the processing from step S1105.
If the close button flag is logical “false” (NO in S1213), the door drive control unit 401 next activates the second timer (S1214). Then, the door drive control unit 401 confirms whether or not the second timer indicates that a predetermined time has elapsed (S1215).

If the time specified in the second timer has not elapsed at the time of step S1215 (NO in S1215), the door drive control unit 401 repeats the process from step S1215 again. That is, the door drive control unit 401 waits until the second timer times the specified time.
If the time specified in the second timer has elapsed at the time of step S1215 (YES in S1215), the door drive control unit 401 repeats the process from step S1105.

  As described above, the flowcharts described from FIG. 5 to FIG. 12 are all simultaneously operated by a known multitask or multithread.

Operations of the flowcharts shown in FIGS. 11 and 12 will be described with reference to time charts.
FIGS. 13A, 13 </ b> B, 13 </ b> C, 13 </ b> D, and 13 </ b> E are time charts illustrating the opening / closing operation of the door 110 controlled by the door drive control unit 401 on the time axis.
FIGS. 13A and 13C are time charts showing the opening / closing operation of the door 110. The horizontal axis is the time axis, and the vertical axis schematically shows the opening / closing position of the door 110. In the subsequent time charts, the horizontal axis indicates the time axis. Also, in FIGS. 17A and 17B and FIGS. 20A and 20B described later, the vertical axis schematically indicates the opening / closing position of the door 110.

FIGS. 13B and 13E are time charts showing the logical state of the door sensor 201. FIG. Between time t1308 and t1309 and between time t1322 and t1323, door sensor 201 detects the presence of a passenger passing through door 110.
In addition, since it is a design matter how to connect the electrical logical value of the door sensor 201 and whether or not a passenger is detected, in this embodiment, the state that “passenger is detected” is defined as logical “true”. . Similarly, the state in which the entrance sensor 202 detects a passenger, the state in which the open button 302 and the close button 303 are pressed, the state in which the door open switch 402 detects that the door 110 has been fully opened, and the door close switch 403 in the door 110 The state in which it is detected that the switch is closed is also defined as “true” of logic for each switch or sensor.

  FIG. 13D is a time chart showing the logical state of the close button 303. The close button 303 is pressed by the passenger between the time t1315 and t1316 and between the time t1320 and t1321.

First, the most basic door opening / closing operation of the door drive control unit 401 when neither the open button 302 nor the close button 303 is pressed by the passenger and the door sensor 201 and the entrance sensor 202 do not detect the presence of the passenger. Will be explained.
When the car 102 arrives at an arbitrary stop floor 109 at time t1301, the door 110 starts to open from the closed position, and the door 110 opens completely at time t1302. In step S902 in FIG. 9, the door drive control unit 401 sets the door drive flag and the door open / close flag to open the door 110, and receives the door 110 opening operation command in step S1004 in FIG. It is because it issues to the door motor drive part which is not illustrated. Then, during the time t1301 to the time t1302, the state change of the door opening switch 402 is monitored in step S1102 of FIG.

  Next, at time t1302, the door opening switch 402 detects that the door 110 has been fully opened. Then, the door drive control unit 401 exits the monitoring loop in step S1102 of FIG. 11 (YES in S1102), and turns on the first timer (S1103). Then, the door drive control unit 401 waits for the time set in the first timer (S1104). If the door sensor 201 and the entrance sensor 202 do not detect the presence of a passenger within the time set in the first timer and the open button 302 and the close button 303 are not pressed, the door drive control unit 401 After the door 110 is opened for the time set in the first timer (from t1302 to t1303), a door drive flag and a door open / close flag are set to close the door 110 in step S1105.

In response to this, the door drive control unit 401 issues a door 110 closing operation command to a door motor drive unit (not shown) in step S1006. If the door sensor flag (S1206), the inlet sensor flag (S1207), and the door open / close flag (S1208) do not change, the door close switch 403 detects that the door 110 is closed at time t1304 (S1209). YES), all the control programs for door opening / closing control in the door drive control unit 401 are terminated.
That is, if neither the open button 302 nor the close button 303 is pressed and the door sensor 201 and the entrance sensor 202 do not detect the presence of a passenger, the door drive control unit 401 opens the door 110 for the time set in the first timer. Open and then close door 110.

Next, when neither the open button 302 nor the close button 303 is pressed by the passenger and the door sensor 201 detects the presence of a passenger passing through the door 110 while the door 110 is closing, the door drive control unit 401 opens and closes the door. The operation will be described.
When the car 102 arrives at an arbitrary stop floor 109 at the time t1305, the door 110 starts to open from the closed position, and the door 110 opens completely at the time t1306.

  Next, at time t1306, the door opening switch 402 detects that the door 110 has been fully opened. Then, the door drive control unit 401 exits the monitoring loop in step S1102 of FIG. 11 (YES in S1102), and turns on the first timer (S1103). Then, the door drive control unit 401 waits for the time set in the first timer (S1104). If the door sensor 201 and the entrance sensor 202 do not detect the presence of a passenger within the time set in the first timer and the open button 302 and the close button 303 are not pressed, the door drive control unit 401 After the door 110 is opened for the time set in the first timer (from t1306 to t1307), a door drive flag and a door open / close flag are set to close the door 110 in step S1105.

  In response to this, the door drive control unit 401 issues a door 110 closing operation command to a door motor drive unit (not shown) in step S1006. Then, the door sensor 201 detects the presence of a passenger passing through the door 110 at the timing from the time t1308 to the time t1309 in the middle after the door 110 starts to close at time t1307 (YES in step S503 in FIG. 5). Then, in step S504, the door drive control unit 401 sets the door sensor flag to logic “true”, and sets the door open / close flag to logic that means “open door 110” (S505). In response to this, the door drive control unit 401 branches to NO in step S1206 in the flowchart of FIG. 12 and waits until the door 110 is fully opened (S1212).

  When the door 110 is fully opened at time t1310 (YES in S1212), the door drive control unit 401 confirms the close button flag (S1213). If the close button 303 is not pressed (NO in S1213), the door drive control unit 401 turns on the second timer (S1214) and waits for the time set in the second timer (S1215). When the time set in the second timer elapses at time t1311, the door drive control unit 401 performs the operation of closing the door 110 again (S1105), and when the door close switch 403 detects that the door 110 is closed at time t1312. (YES in S1209), all control programs for door opening / closing control in the door drive control unit 401 are terminated.

  That is, when neither the open button 302 nor the close button 303 is pressed by the passenger and the door sensor 201 detects the presence of a passenger passing through the door 110 while the door 110 is closing, the door drive control unit 401 opens the door 110. After opening again, the door 110 is opened for the time set in the second timer, and then the door 110 is closed.

Next, the door opening / closing operation of the door drive control unit 401 when the close button 303 is pressed by the passenger while the door 110 is fully opened and the door 110 is being opened for the time set in the first timer will be described. To do.
When the car 102 arrives at an arbitrary stop floor 109 at time t1313, the door 110 starts to open from the closed position, and the door 110 opens completely at time t1314.
Next, at time t1314, the door opening switch 402 detects that the door 110 has been fully opened. Then, the door drive control unit 401 exits the monitoring loop in step S1102 of FIG. 11 (YES in S1102), and turns on the first timer (S1103). Then, the door drive control unit 401 waits for the time set in the first timer (S1104).

  The passenger presses the close button 303 from time t1315 to t1316 within the time set in the first timer. Then, the door drive control unit 401 sets the close button flag to logical “true” (step S704 in FIG. 7), and the first timer is counting time (YES in S705), so the timing of the first timer is ended. (S706). This end operation of the time measuring operation by the door drive control unit 401 exits the time waiting loop of the first timer in step S1104 of FIG. As a result, the door drive control unit 401 operates the door drive flag and the door open / close flag without waiting for the set time of the first timer at time t1315 (S1105). Then, the door drive control unit 401 issues a door 110 closing operation command to the door motor driving unit, and the door 110 starts to close.

  Thereafter, if the door sensor flag (S1206), the inlet sensor flag (S1207), and the door opening / closing flag (S1208) do not change, the door closing switch 403 detects that the door 110 is closed at time t1317 (S1209). YES), all the control programs for door opening / closing control in the door drive control unit 401 are completed.

  That is, when the close button 303 is pressed while the door 110 is open for the time set in the first timer, the door drive control unit 401 immediately closes the door 110.

Next, while the door 110 is fully opened and the door 110 is being opened for the time set in the first timer, the passenger closes the door 110 while the door 110 is closed after the close button 303 is pressed by the passenger. The door opening / closing operation of the door drive control unit 401 when the presence of a passenger passing through the door is detected will be described.
When the car 102 arrives at an arbitrary stop floor 109 at the time t1318, the door 110 starts to open from the closed position, and the door 110 is fully opened at the time t1319.
Next, at time t1319, the door opening switch 402 detects that the door 110 has been fully opened. Then, the door drive control unit 401 exits the monitoring loop in step S1102 of FIG. 11 (YES in S1102), and turns on the first timer (S1103). Then, the door drive control unit 401 waits for the time set in the first timer (S1104).

  The passenger presses the close button 303 from time t1320 to time t1321 within the time set in the first timer. Then, the door drive control unit 401 sets the close button flag to logical “true” (step S704 in FIG. 7), and the first timer is counting time (YES in S705), so the timing of the first timer is ended. (S706). This end operation of the time measuring operation by the door drive control unit 401 exits the time waiting loop of the first timer in step S1104 of FIG. As a result, the door drive control unit 401 operates the door drive flag and the door open / close flag without waiting for the set time of the first timer at time t1320 (S1105). Then, the door drive control unit 401 issues a door 110 closing operation command to the door motor driving unit, and the door 110 starts to close.

  Next, the door sensor 201 detects the presence of a passenger passing through the door 110 at the timing from the time t1322 to the time t1323 halfway after the door 110 starts to close at the time t1320 (YES in step S503 in FIG. 5). Then, in step S504, the door drive control unit 401 sets the door sensor flag to logic “true”, and sets the door open / close flag to logic that means “open door 110” (S505). In response to this, the door drive control unit 401 branches to NO in step S1206 in the flowchart of FIG. 12 and waits until the door 110 is fully opened (S1212).

  When the door 110 is fully opened at time t1324 (YES in S1212), the door drive control unit 401 confirms the close button flag (S1213). Since the close button 303 was previously pressed at time t1320 (YES in S1213), the door drive control unit 401 may turn on the second timer or wait for the time set in the second timer to elapse. If the door closing switch 403 detects that the door 110 is closed at time t1325 (YES in S1209), the door opening / closing control in the door drive control unit 401 is immediately performed again. Exit all control programs for.

  That is, when the door sensor 201 detects the presence of a passenger passing through the door 110 while the door 110 is closed after the close button 303 is pressed by the passenger, the door drive control unit 401 opens the door 110 again. The door 110 is immediately closed without timing by the second timer.

[Second Embodiment: Operation]
In the elevator system 101 according to the first embodiment, when the passenger gets out of the car 102 after pressing the close button 303, or when the passenger gets out of the car 102 while pressing the close button 303, the door drive control unit 401 is If the door sensor 201 and the entrance sensor 202 do not detect a passenger after the door 110 has been fully opened, the door 110 is immediately closed. That is, after the door 110 is fully opened, the waiting time by the second timer is not waited. This operation is the same when the passenger gets in immediately after the passenger presses the close button 303. In other words, the first embodiment does not consider the direction of passenger movement after the close button 303 is pressed. Therefore, the safety when the passenger gets on the car 102 by setting the door drive control unit 401 to close the door 110 without waiting for the waiting time of the second timer only when the passenger gets off. Can be improved.

From here, the elevator system 101 which concerns on 2nd embodiment which implement | achieves such operation | movement is demonstrated.
The elevator system 101 of the second embodiment has exactly the same hardware configuration as the elevator system 101 of the first embodiment. The difference is that a program incorporated in the door drive control unit 401 and a flag are added.

14 and 15 are flowcharts showing the flow of the control operation of the inside / outside flag.
In the elevator system 101 according to the second embodiment, a flag for detecting a state in which a passenger has got off the car 102 is added to the flag group 405 as an inside / outside flag. 14 and 15 are flowcharts of a program for controlling the inside / outside flag.

When the car 102 arrives at an arbitrary stop floor 109 (S1401), the door drive control unit 401 first sets the inside / outside flag to logical “false” (S1402).
Next, the door drive control unit 401 confirms whether or not the door sensor flag is logical “true” (S1403).

If the door sensor flag is logical “true” (YES in S1403), the door drive control unit 401 next waits until the door sensor flag changes to logical “false” (S1404).
If the door sensor flag is converted to logic “false” (YES in S1404), the door drive control unit 401 next checks whether the entrance sensor flag is logic “true” (S1405).
If the entrance sensor flag is logical “true” (YES in S1405), the door drive control unit 401 sets the internal / external flag to logical “true” (S1406).
If the entrance sensor flag is logical “false” (NO in S1405), the door drive control unit 401 proceeds to step S1407 without operating the inside / outside flag. Then, the door drive control unit 401 waits until the entrance sensor flag changes to logical “false” (S1407).

The description of the flowchart will be continued with reference to FIG.
When the entrance sensor flag changes to logic “false”, the door drive control unit 401 next checks whether or not the door closing switch 403 detects that the door 110 is closed (S1508).
If the door 110 is closed (YES in S1508), the door drive control unit 401 ends the series of processes (S1509).
If the door 110 is not closed (NO in S1508), the door drive control unit 401 next checks whether or not the entrance sensor flag is logical “true” (S1510).
If the entrance sensor flag is logical “false” (NO in S1510), the door drive control unit 401 next checks whether the door sensor flag is logical “true” (S1511).
If the door sensor flag is logical “false” (NO in S1511), the door drive control unit 401 repeats the process from step S1508 again. That is, as long as both the entrance sensor flag and the door sensor flag are logical “false”, steps S1508, S1510, and S1511 are continuously looped until the door 110 is closed.

  If the entrance sensor flag is logical “true” in step S1510 (YES in S1510), or if the door sensor flag is logical “true” in step S1511 (YES in S1511), the door drive control unit 401. Sets the inside / outside flag to logic “false” (S1512) and repeats the processing from step S1403.

  The inside / outside flag is set when the door sensor flag changes from logic “true” to “false”, that is, when the logic falls (S1403 → S1404), and when the entrance sensor flag is logic “true” (S1405). YES), the logic becomes “true” (S1406). This focuses on the fact that the detection timing of passengers in the door sensor 201 and the entrance sensor 202 differs depending on the movement direction of the passengers. Even after the inside / outside flag is once set to logic “true” (S1406), if either of the door sensor 201 and the entrance sensor 202 detects the presence of a passenger (YES in S1510 and YES in S1511), the logic “ Returning to "false" (S1512), the passenger detection operation is repeated again.

  FIG. 16 is a flowchart showing a flow of control operation for closing the door 110. FIG. 16 is almost the same as the flowchart of FIG. 12 except that step S1616 is added after step S1213.

In FIG. 16, after looping until the door 110 is fully opened (YES in S1212), the door drive control unit 401 confirms whether or not the close button flag is logical “true” (S1213).
If the close button flag is logical “true” (YES in S1213), the door drive control unit 401 further confirms whether the inside / outside flag is logical “true” (S1616).
If the inside / outside flag is logical “true” (YES in S1616), the door drive control unit 401 repeats the processing from step S1105.

If the close button flag is logical “false” in step S1213 (NO in S1213), or if the internal / external flag is logical “false” in step S1616 (NO in S1616), the door drive control unit 401 Next, the second timer is started (S1214). Then, the door drive control unit 401 confirms whether or not the second timer indicates that a predetermined time has elapsed (S1215).
If the time specified in the second timer has not elapsed at the time of step S1215 (NO in S1215), the door drive control unit 401 repeats the process from step S1215 again. That is, the door drive control unit 401 waits until the second timer times the specified time.
If the time specified in the second timer has elapsed at the time of step S1104 (YES in S1215), the door drive control unit 401 repeats the processing from step S1105.

The operation of the flowcharts shown in FIGS. 14, 15 and 16 will be described with reference to a time chart.
FIGS. 17A, 17 </ b> B, 17 </ b> C, 17 </ b> D, and 17 </ b> E are time charts illustrating the opening / closing operation of the door 110 controlled by the door drive control unit 401 on the time axis.
FIGS. 17A and 17B are time charts showing the opening / closing operation of the door 110. In order to describe in detail the operation between the time t1701 and the time t1702 and the operation between the time t1710 and the time t1711, FIG. 17B extends the time axis compared to FIG.
FIG. 17C is a time chart showing the logical state of the close button 303. Between time t1703 and t1704 and between time t1712 and t1713, the close button 303 is pushed by the passenger.
FIG. 17D is a time chart showing the logical state of the door sensor 201. Between time t1705 and t1707 and between time t1715 and t1717, door sensor 201 detects the presence of a passenger passing through door 110.
FIG. 17E is a time chart showing the logical state of the inlet sensor 202. Between time t1706 and t1708 and between time t1714 and t1716, entrance sensor 202 detects the presence of a passenger passing through the entrance.

  First, when the door 110 is fully opened and the door 110 is being opened for the time set in the first timer, the passenger pushes the close button 303 and then the passenger 110 gets off the car 102 while the door 110 is closed. The door opening / closing operation of the door drive control unit 401 will be described.

  The passenger presses the close button 303 from time t1703 to t1704 within the time set in the first timer. Then, the door drive control unit 401 sets the close button flag to logical “true” (step S704 in FIG. 7), and the first timer is counting time (YES in S705), so the timing of the first timer is ended. (S706). This end operation of the time measuring operation by the door drive control unit 401 exits the time waiting loop of the first timer in step S1104 of FIG. As a result, the door drive control unit 401 operates the door drive flag and the door opening / closing flag without waiting for the set time of the first timer at time t1703 (S1105). Then, the door drive control unit 401 issues a door 110 closing operation command to the door motor driving unit, and the door 110 starts to close.

  Next, the passenger 110 gets out of the car 102 after the door 110 starts to close at time t1703. Then, at the timing from time t1705 to time t1707, the door sensor 201 detects the presence of a passenger passing through the door 110 (YES in step S503 in FIG. 5), and at the timing from time t1706 to time t1708, a little later. The sensor 202 detects the presence of a passenger passing through the entrance (YES in step S603 in FIG. 6).

  When the door sensor 201 detects a passenger at time t1705 (YES in step S1403 in FIG. 14) and the door sensor 201 no longer detects the presence of a passenger at time t1707 (FIG. 14). In response to the fact that the entrance sensor 202 detects the presence of a passenger (YES in S1405), the inside / outside flag is set to logic "true" (S1406). When the door 110 is fully opened at time t1709 (YES in S1212), the close button 303 is pressed at time t1703 (YES in S1213 in FIG. 16), and the inside / outside flag is logic at time t1707. In response to having become “true” (YES in S1616), the door drive control unit 401 immediately turns on the second timer, and does not wait for the time set in the second timer to elapse. The operation of closing the door 110 again is performed (S1105).

  That is, the door drive control unit 401 immediately closes the door 110 without starting the second timer only when the close button flag is true and the inside / outside flag is true. That is, when the close button 303 is pressed and the passenger gets out of the car 102, the door 110 is immediately closed immediately after the door 110 is fully opened.

  Next, while the door 110 is fully opened and the door 110 is being opened for the time set in the first timer, the passenger pushes the close button 303 and then the passenger 110 enters the car 102 while the door 110 is closed. The door opening / closing operation of the door drive control unit 401 when riding is described.

  The passenger presses the close button 303 from time t1712 to t1713 within the time set in the first timer. Then, the door drive control unit 401 sets the close button flag to logical “true” (step S704 in FIG. 7), and the first timer is counting time (YES in S705), so the timing of the first timer is ended. (S706). This end operation of the time measuring operation by the door drive control unit 401 exits the time waiting loop of the first timer in step S1104 of FIG. As a result, the door drive control unit 401 operates the door drive flag and the door open / close flag without waiting for the set time of the first timer at time t1712 (S1105). Then, the door drive control unit 401 issues a door 110 closing operation command to the door motor driving unit, and the door 110 starts to close.

  Next, after the door 110 starts to close at time t1712, the passenger gets into the car 102. Then, at the timing from time t1714 to time t1716, the entrance sensor 202 detects the presence of a passenger passing through the entrance (YES in step S603 in FIG. 6), and at a timing slightly later than the timing from time t1715 to time t1717, the door sensor. 201 detects the presence of a passenger passing through door 110 (YES in step S503 in FIG. 5).

  When the door sensor 201 detects a passenger at time t1715 (YES in step S1403 in FIG. 14) and the door sensor 201 no longer detects the presence of a passenger at time t1717 (FIG. 14). In response to the fact that the entrance sensor 202 has not detected the presence of a passenger (NO in S1405), the inside / outside flag is left as logic "false". When the door 110 is fully opened at time 1718 (YES in S1212), the close button 303 is pressed at time t1712 (YES in S1213 in FIG. 16), and the inside / outside flag is logical at time t1717. In response to being “false” (NO in S1616), the door drive control unit 401 controls to turn on the second timer (S1214), and the time set in the second timer (from t1718 to t1719) Wait for the progress (S1215).

  That is, even if the close button 303 is pressed, if the passenger gets on the car 102, after the door 110 has fully opened, the door 110 is closed after waiting for the waiting time of the second timer.

[Third embodiment: Operation]
In the elevator system 101 according to the second embodiment, only when the passenger gets out of the car 102 after pressing the close button 303, the door drive control unit 401 opens the door 110, If the entrance sensor 202 does not detect a passenger, the door 110 is immediately closed. That is, after the door 110 is fully opened, the waiting time by the second timer is not waited. This operation does not take into account the speed at which passengers get off.

  By the way, it goes without saying that elevator passengers are not limited to adults. As a matter of course, there are also passengers whose movement speed is slow, such as children, elderly people, or people with physical disabilities. When such a passenger gets off the elevator, if the door 110 is suddenly closed, an accident such as being caught by the door 110 may occur. Therefore, the moving speed of the passenger is detected, and the waiting time of the second timer is set for the passenger having a slow moving speed. By doing so, accidents can be prevented in advance, and the safety of passengers especially when they are physically weak can be improved.

Hereafter, the elevator system 101 which concerns on 3rd embodiment which implement | achieves such operation | movement is demonstrated.
The elevator system 101 of the third embodiment has the same hardware configuration as the elevator system 101 of the first embodiment and the second embodiment. The difference is that a program incorporated in the door drive control unit 401 and a flag are added.

FIG. 18 is a flowchart showing the flow of the control operation of the early closing flag.
In the elevator system 101 according to the third embodiment, the flag group 405 is an early closing flag for detecting a state in which a passenger has quickly got out of the car 102 or a passenger has quickly entered the car 102. A flag has been added. FIG. 18 is a flowchart of a program for controlling the early closing flag.

When the car 102 arrives at an arbitrary stop floor 109 (S1801), the door drive control unit 401 first sets the early closing flag to logic “false” (S1802).
Next, the door drive control unit 401 confirms whether the door sensor flag is logical “true” (S1803).

If the door sensor flag is logical “false” (NO in S1803), the door drive control unit 401 next checks whether or not the entrance sensor flag is logical “true” (S1804).
In any case, whether the door sensor flag is logical “true” (YES in S1803) or the entrance sensor flag is logical “true” (YES in S1804), the door drive control unit 401 performs the third operation. The timer is turned on, and the early closing flag is set to logic “false” (S1805).

Next, the door drive control unit 401 confirms whether or not the third timer indicates that a predetermined time has elapsed (S1806).
If the time specified in the third timer has elapsed at the time of step S1806 (YES in S1806), the door drive control unit 401 next detects that the door 110 is closed by the door close switch 403. It is confirmed whether or not (S1807).
If the door 110 is closed (YES in S1807), the door drive control unit 401 ends the series of processes (S1808).
If the door 110 is not closed (NO in S1807), the door drive control unit 401 repeats the processing from step S1803 again.

If the time specified in the third timer has not elapsed at the time of step S1806 (NO in S1806), the door drive control unit 401 next determines whether or not the door sensor flag is logical “false”. Confirmation is made (S1809).
If the door sensor flag is logical “false” (YES in S1809), the door drive control unit 401 next checks whether the entrance sensor flag is logical “false” (S1810).
Only when the door sensor flag is logical “false” (YES in S1809) and the entrance sensor flag is logical “false” (YES in S1810), the door drive control unit 401 sets the early closing flag to logical. “True” is set (S1811), and it is checked in step S1807 whether the door 110 is closed.

If the door sensor flag is logical “true” (NO in S1809) or the entrance sensor flag is logical “true” (NO in S1810), the door drive control unit 401 in step S1806. Wait for the time specified in the third timer.
Also, at the time of step S1804, if the entrance sensor flag is logical “false” (NO in S1804), it is confirmed in step S1807 whether the door 110 is closed.

  That is, when either the door sensor flag or the entrance sensor flag changes to logic “true” (S1803 and S1804), the third timer is turned on (S1805). By the time when the timing operation of the third timer is completed (S1806), when both the door sensor flag and the entrance sensor flag are switched to logic “false” (S1809 and S1810), the early closing flag is set to logic “true”. (S1811) and wait until the door 110 is closed (S1807).

  Even after the early closing flag is set to logic “true” (S1811 → S1807 → S1803), if either the door sensor flag or the entrance sensor flag changes to logic “true”, the presence of a passenger is detected. Therefore, the third timer is turned on again, the early closing flag is returned to the logic “false” (S1805), and the determination processing after step S1806 is repeated.

  FIG. 19 is a flowchart showing a flow of control operation for closing the door 110. FIG. 19 is almost the same as the flowchart of FIG. 16 except that the process is changed to step S1916 instead of step S1616.

In FIG. 19, after looping until the door 110 is fully opened (YES in S1212), the door drive control unit 401 confirms whether or not the close button flag is logical “true” (S1213).
If the close button flag is logical “true” (YES in S1213), the door drive control unit 401 further checks whether or not the early close flag is logical “true” (S1916).

If the early closing flag is logical “true” (YES in S1916), the door drive control unit 401 repeats the processing from step S1105.
If the close button flag is logical “false” in step S1213 (NO in S1213), or if the early close flag is logical “false” in step S1916 (NO in S1916), the door drive control unit 401 then starts the second timer (S1214). Then, the door drive control unit 401 confirms whether or not the second timer indicates that a predetermined time has elapsed (S1215).

If the time specified in the second timer has not elapsed at the time of step S1215 (NO in S1215), the door drive control unit 401 repeats the process from step S1215 again. That is, the door drive control unit 401 waits until the second timer times the specified time.
If the time specified in the second timer has elapsed at the time of step S1215 (YES in S1215), the door drive control unit 401 repeats the process from step S1105.

The operations of the flowcharts shown in FIGS. 18 and 19 will be described with reference to time charts.
FIGS. 20A, 20 </ b> B, 20 </ b> C, 20 </ b> D, and 20 </ b> E are time charts illustrating the opening / closing operation of the door 110 controlled by the door drive control unit 401 on the time axis.
FIGS. 20A and 20B are time charts showing the opening / closing operation of the door 110. In order to describe in detail the operation between the time t2001 and the time t2002, FIG. 20 (b) extends the time axis compared to FIG. 20 (a).
FIG. 20C is a time chart showing the logical state of the close button 303. The close button 303 is pressed by the passenger between time t2003 and t2004 and between time t2012 and t2013.
FIG. 20D is a time chart showing the logical state of the door sensor 201. Between time t2005 and t2007 and between time t2014 and t2016, the door sensor 201 detects the presence of a passenger passing through the door 110.
FIG. 20E is a time chart showing the logical state of the inlet sensor 202. Between time t2006 and t2008 and between time t2015 and t2017, the entrance sensor 202 detects the presence of a passenger passing through the entrance.

  First, when the door 110 is fully opened and the door 110 is being opened for the time set in the first timer, the passenger pushes the close button 303 and then the passenger 110 gets off the car 102 while the door 110 is closed. The door opening / closing operation of the door drive control unit 401 will be described.

  The passenger presses the close button 303 from time t2003 to t2004 within the time set in the first timer. Then, the door drive control unit 401 sets the close button flag to logical “true” (step S704 in FIG. 7), and the first timer is counting time (YES in S705), so the timing of the first timer is ended. (S706). This end operation of the time measuring operation by the door drive control unit 401 exits the time waiting loop of the first timer in step S1104 of FIG. As a result, the door drive control unit 401 operates the door drive flag and the door open / close flag without waiting for the set time of the first timer at time t2003 (S1105). Then, the door drive control unit 401 issues a door 110 closing operation command to the door motor driving unit, and the door 110 starts to close.

  Next, after the door 110 starts to close at time t2003, the passenger quickly gets out of the car 102. Then, at the timing from time t2005 to time t2007, the door sensor 201 detects the presence of a passenger passing through the door 110 (YES in step S503 in FIG. 5), and at a timing from time t2006 to time t2008, a little later. The entrance sensor 202 detects the presence of a passenger passing through the entrance (YES in step S603 in FIG. 6).

When the door sensor 201 detects a passenger at time t2005 (YES in step S1803 in FIG. 18), the door drive control unit 401 turns on the third timer. The third timer performs a time measuring operation only between time t2005 and time t2021.
At this time, the loop operation is changed from NO in step S1806 to NO in step S1809.
Next, at time t2006, the entrance sensor 202 also detects the presence of a passenger.
At this time, the loop operation from NO in step S1806 to NO in step S1809 remains.
Next, at time t2007, the door sensor 201 does not detect the presence of a passenger.
At this time, the loop operation starts from NO in step S1806, YES in step S1809, and NO in step S1810.
Next, at time t2008 before time t2021 when the third timer finishes timing operation, the entrance sensor 202 also does not detect the presence of a passenger.
At this time, the result of step S1806 is NO, step S1809 is YES, and step S1810 is YES, and the door drive control unit 401 sets the early closing flag to logic “true” (S1811).

  When the door 110 is fully opened at time t2009 (YES in S1212), the close button 303 is pressed at time t2003 (YES in S1213 in FIG. 19), and the early closing flag is set at time t2007. In response to the logic becoming “true” (YES in S 1916), the door drive control unit 401 does not turn on the second timer or wait for the time set in the second timer to elapse. Immediately again, the door 110 is closed again (S1105).

  That is, the door drive control unit 401 immediately closes the door 110 without starting the second timer only when the close button flag is true and the early close flag is true. That is, when the close button 303 is pressed and the passenger gets off the car 102 quickly or gets on the car 102 quickly, the door 110 is immediately closed immediately after the door 110 is fully opened.

  Next, while the door 110 is fully opened and the door 110 is being opened for the time set in the first timer, the passenger presses the close button 303 and then the passenger 110 moves from the car 102 while the door 110 is closed. The door opening / closing operation of the door drive control unit 401 when slowly descending will be described.

  The passenger presses the close button 303 from time t2012 to t2013 within the time set in the first timer. Then, the door drive control unit 401 sets the close button flag to logical “true” (step S704 in FIG. 7), and the first timer is counting time (YES in S705), so the timing of the first timer is ended. (S706). This end operation of the time measuring operation by the door drive control unit 401 exits the time waiting loop of the first timer in step S1104 of FIG. As a result, the door drive control unit 401 operates the door drive flag and the door open / close flag without waiting for the set time of the first timer at time t2012 (S1105). Then, the door drive control unit 401 issues a door 110 closing operation command to the door motor driving unit, and the door 110 starts to close.

  Next, after the door 110 starts to close at time t2012, the passenger slowly gets out of the car 102. Then, at the timing from time t2014 to time t2016, the door sensor 201 detects the presence of a passenger passing through the door 110 (YES in step S503 in FIG. 5), and at the timing from time t2015 to time t2017, a little later. The sensor 202 detects the presence of a passenger passing through the entrance (YES in step S603 in FIG. 6).

When the door sensor 201 detects a passenger at time t2014 (YES in step S1803 in FIG. 18), the door drive control unit 401 turns on the third timer. The third timer performs a time measuring operation only from time t2014 to time t2022.
At this time, the loop operation is changed from NO in step S1806 to NO in step S1809.
Next, at time t2015, the entrance sensor 202 also detects the presence of a passenger.
At this time, the loop operation from NO in step S1806 to NO in step S1809 remains.
Next, at time t2016, the door sensor 201 does not detect the presence of a passenger.
At this time, the loop operation starts from NO in step S1806, YES in step S1809, and NO in step S1810.
Next, at the time t2022, the third timer ends the time measuring operation.
At this point, the process proceeds from YES in step S1806 to step S1807, and the door drive control unit 401 waits for the door 110 to close without operating the early closing flag.

  When the door 110 is fully opened at time t2018 (YES in S1212), the close button 303 is pressed at time t2012 (YES in S1213 in FIG. 16), and the early closing flag is set at time t2022. In response to the logic being “false” (NO in S1916), the door drive control unit 401 turns on the second timer (S1214), and the time set in the second timer (from t2018 to t2019) (S1215).

  That is, even if the close button 303 is pressed, if the passenger moving speed is slow, after the door 110 is fully opened, the door 110 is closed after waiting for the waiting time of the second timer.

In the first to third embodiments described above, the following application examples are possible.
(1) When there is no passenger in the car 102, a process may be added in which the door 110 is immediately closed without operating the second timer.
FIG. 21 is a functional block diagram of the door drive control unit 2101 and its peripheral devices provided in the in-car operation panel 107.
The difference from FIG. 4 is that a human sensor 2102 attached to the ceiling in the car 102 is connected to the door drive control unit 2101. The human sensor 2102 outputs a predetermined logic signal when there is no passenger in the car 102. In place of or in addition to the human sensor 2102, a load sensor is attached to the floor of the car 102 or the connection portion with the main rope 105 to detect the presence or absence of a passenger by the difference in the load of the car 102. May be. Or you may detect the presence or absence of a passenger based on an image signal using the image signal of a surveillance camera. The means for detecting the presence or absence of a passenger, such as the human sensor 2102, the load sensor, and the monitoring camera, can be collectively referred to as a passenger detection unit.

FIG. 22 is a part of a flowchart showing a flow of control operation for closing the door 110. This corresponds to steps S1213 to S1215 in FIG.
In FIG. 22, the door drive control unit 2101 checks whether or not the close button flag is logical “true” (S1213).
If the close button flag is logical “true” (YES in S1213), the door drive control unit 2101 further checks whether the inside / outside flag is logical “true” (S1616).
If the inside / outside flag is logical “true” (YES in S1616), the door drive control unit 2101 repeats the processing from step S1105.

If the close button flag is logical “false” in step S1213 (NO in S1213), the door drive control unit 2101 further detects that the passenger sensor 2102 does not have any passengers in the car 102. It is confirmed whether or not (S2201). If there is no passenger (YES in S2201), the door drive control unit 2101 repeats the process from step S1105.
If there is a passenger in step S2201 (NO in S2201), or if the inside / outside flag is logical “false” in step S1616 (NO in S1616), the door drive control unit 2101 next starts the second timer. (S1214). Then, the door drive control unit 2101 confirms whether or not the second timer indicates that a predetermined time has elapsed (S1215).

If the time specified in the second timer has not elapsed at the time of step S1215 (NO in S1215), the door drive control unit 2101 repeats the process from step S1215 again. That is, the door drive control unit 2101 waits until the second timer times the specified time.
If the time specified in the second timer has elapsed at the time of step S1215 (YES in S1215), the door drive control unit 2101 repeats the processing from step S1105.

(2) When shifting to the operation of immediately closing the door 110, a process of giving a predetermined warning to the passengers in the car 102 and calling attention may be added. Warning methods include blinking the close button 303, playing a sound announcement, making a warning sound, displaying a message by providing a display unit such as a liquid crystal display panel on the in-car operation panel 107, or on the door or around the door. For example, a method of providing a light emitter and blinking or lighting it can be used. A warning message to passengers, such as the light emission part and light emission control part of the close button 303, the light emission part and light emission control part of the light emitter around the door or the door, the sound announcement reproduction part, the warning sound generation part, and the warning message display part. The means for transmitting can be collectively referred to as a warning information transmitting unit.
Step S2202 in FIG. 22 is a process for issuing a warning. That is, when the door 110 is closed without operating the second timer, the warning operation described above is executed.

  (3) When the door drive control unit 401 or the door drive control unit 2101 closes the door 110, the door 110 is closed by operating the second timer, and the door 110 is closed without operating the second timer. Thus, when the moving speed of the door 110 is changed, it is possible to expect improvement in speediness and safety. When the second timer is operated, the door 110 is driven at a low speed, and when the second timer is not operated, the door 110 is driven at a high speed. By doing so, as described in the above-described third embodiment, it is possible to ensure the safety of passengers, particularly in physically weak people.

In the present embodiment, the elevator system 101 is disclosed.
The door drive control unit 401 of the elevator system 101 according to the first embodiment sets the close button 303 immediately after the passenger presses the close button 303 or when the passenger gets out of the car 102 while pressing the close button 303. In response to the pressing and both the door sensor 201 and the entrance sensor 202 no longer detecting passengers, the door 110 is immediately closed without setting the waiting time of the second timer. By processing in this way, the door 110 can be quickly closed while ensuring passenger safety.
The door drive control unit 401 of the elevator system 101 according to the second embodiment sets the close button 303 immediately after the passenger presses the close button 303 or when the passenger gets off the car 102 while pressing the close button 303. The door 110 is immediately closed without detecting the waiting time of the second timer by detecting that it has been pushed and that the passenger has exited the car 102 from the outputs of the door sensor 201 and the entrance sensor 202. By processing in this way, the door 110 can be quickly closed only when the passenger gets out of the car 102 while ensuring the safety of the passenger.
The door drive control unit 401 of the elevator system 101 according to the third embodiment sets the close button 303 immediately after the passenger presses the close button 303 or when the passenger gets out of the car 102 while pressing the close button 303. It is detected from the output of the door sensor 201 and the entrance sensor 202 that the passenger has quickly got off or got on the car 102, and the door 110 is immediately set without setting the waiting time of the second timer. Close. By processing in this way, the door 110 can be quickly closed when necessary while ensuring the safety of a passenger who is slow in movement and considered to be weak in terms of motion.
