Description

  The present invention relates to an elevator control system.

  The elevator plays an important role as the main means of transportation in the building and transports many passengers. Passengers usually call the car in the elevator hall and enter the car with the door fully open after arrival. However, some passengers rush in when the door is closed, so a function to protect passenger safety is essential. As an example of safety means for protecting passengers, Patent Document 1 discloses a mirror-shaped door that is blind spotted from the field of view of an elevator driver or a passenger near a car operation panel and that allows the passenger to enter from an invisible direction. Disclosed is an elevator system that provides and eliminates the possibility of closing the door without being aware of the passengers who are suddenly boarding.

  In addition to this, in Patent Document 2, if a passenger passes within the set time using two sensors installed in the hall, it is judged as a rush passenger, and if the passenger in the car is not full, a rush passenger is detected. It is disclosed that a control elevator device that holds the elevator in a door open state is configured to protect passenger safety.

  However, in the method described in Patent Document 1, if the passenger does not look at the mirror door without closing the mirror door, there is a possibility that the passenger will be quickly caught by the car door. In addition, in the method described in Patent Document 2, when the passengers in the car are full, the fullness is detected and the door is closed, so it is possible to ensure the safety of a rushing passenger who tries to get on without being aware of the fullness. There wasn't.

  Then, an object of this invention is to provide the elevator control system which can open and close a car side door, ensuring a passenger's safety.

  In order to solve the problems, the present invention provides an operation panel that is arranged in a car and outputs a signal corresponding to an operation, and a blind spot of an operating panel operator in the car in the area of a landing hall. A human sensor that detects whether or not a target person exists within the detection range, and a car side that opens and closes the car-side door of the car according to a door open command or a door close command. A door driving device, and a controller that monitors signals from the operation panel and signals from the human sensor as input signals, and controls driving of the car-side door driving device based on the input signals, and When the controller receives a signal for closing the car-side door from the operation panel, the controller outputs a door-closing command to the car-side door driving device, and outputs the door-closing command from the human sensor. Within the detection range When a person detection signal indicating that an elephant person is present is received, output of the door closing command to the car side door driving device is stopped, a door opening command is output, and the car side door is opened. It is made to open.

  According to the present invention, the car-side door can be opened and closed while ensuring the safety of passengers.

It is a top view which shows the structure of the hall which concerns on embodiment of this invention, and a passenger car. 1 is a block diagram of an elevator control system according to an embodiment of the present invention. It is a flowchart for demonstrating the process of the elevator control system which concerns on embodiment of this invention.

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

  In the present embodiment, when the door is closed in the elevator hall, a human sensor installed on the back of the operation panel of the car detects a rushing passenger who tries to get into the elevator from an area that becomes the blind spot of the operation panel operator. When it is determined that the passenger is about to get into the elevator, the car-side door that is being closed is automatically reversed and the door is opened to ensure the safety of the rushed passenger.

  FIG. 1 is a plan view showing configurations of a landing hall and a car according to an embodiment of the present invention. In FIG. 1, a landing side door 2 is installed in a landing hall 1, and a call registration button 3 for making an elevator call is installed. A car-side door 5 is installed opposite to the landing-side door 2 in a car (elevator car) 4 that moves up and down in the elevator hoistway. The landing side door 2 is configured to open and close in conjunction with the car side door 5 by a door motor (not shown). Two operation panels 6 are arranged on the wall surface of the car 4 in the vicinity of the car-side door 5, and a human sensor 7 that senses a person through the wall is provided on the back side of each operation panel 6. is set up. Each operation panel 6 has a destination floor button, an open / close button, an emergency button, and the like, is arranged in the car 4, and outputs a signal corresponding to an operation (button operation) of the operation panel operator (passenger).

  Each human sensor 7 is, for example, an area of the hall 1, and a certain area that is a blind spot of an operation panel operator (passenger) in the car 4 is detected in a detection range (for example, human sensor detection range 8, 9), a detection signal (a signal by infrared rays, ultrasonic waves, or visible light) is transmitted from the operation panel side of the car 4 toward the detection range, and a detection signal reflected from the detection range is received and within the detection range. Is a sensor that detects whether or not a target person exists.

  The human sensor detection ranges 8 and 9 of the human sensors 7 are ranges in the hall 1 on the front side of the operation panels 6, and are operation panel operators (passengers 10 and 11) who operate the operation panels 6. It is set in the range that becomes the blind spot. For example, the human sensor detection range 8 is set to a range in which the passenger 10 cannot recognize the passenger 12, and the human sensor detection range 9 is set to a range in which the passenger 11 cannot recognize the passengers 13 and 14. Yes. Further, since the human detection sensor detection ranges 8 and 9 can be changed depending on the object, the distance from each human detection sensor 7 is 2 to 3 as the human detection sensor detection ranges 8 and 9 of each human detection sensor 7. It is a meter and is set to a substantially square area.

  In a general office building or the like, a call registration button 3 is installed in the hall 1, and the passenger presses the call registration button 3 and calls the car 4 before moving to the upper or lower floor. When the passenger who has arrived in the arrival car 4 registers the destination floor on the operation panel 6 in the car 4 and presses the “close” button, the car-side door 5 and the landing-side door 2 are closed, and the ride The movement of the car 4 to the destination floor is started. The passenger who presses the call registration button 3 gets into the car 4 at this point, confirms that there are no other passengers in the vicinity, and presses the “close” button, so that the car-side door 5 and the landing-side door 2 Can be closed. At this time, even if the passenger who has entered the car 4 is in the blind spot on the back side of the operation panel 6 (the area in the hall 1 that is the blind spot of the passenger operating the operation panel 6), this passenger Cannot be confirmed. For this reason, when the car-side door 5 and the landing-side door 2 are closed, a rushing passenger 12 who tries to get into the car 4 from the landing hall 1 moves to the landing-side door 2 and the car-side door 5 that are closed. There is a danger of being caught.

  Therefore, in the present embodiment, in order to avoid this danger, when the human sensor 7 detects a person in one of the human sensor detection ranges 8 and 9 in the hall 1, the car-side door 5 and The door closing operation of the landing side door 2 is reversed and the door opening operation is performed. In addition to the case where the passenger in the car 4 presses the “close” button, the same process is performed when the car-side door 5 and the landing-side door 2 are automatically closed after a predetermined time has elapsed. It is a configuration to execute. Furthermore, even when the car 4 is full of passengers, if a rush passenger is detected, the doors of the car side door 5 and the landing side door 2 are automatically used to ensure the safety of the rush passenger. In this configuration, the closing operation is reversed and the door is opened.

  FIG. 2 is a block diagram of the elevator control system according to the embodiment of the present invention. In FIG. 2, the elevator control system includes an elevator control device 20, an operation panel 6, a human sensor 7, a car-side door drive device 30, and a car drive device 31. The feeling sensor 7, the car-side door driving device 30 and the car driving device 31 are connected to the elevator control device 20. In FIG. 2, only one operation panel 6 and human sensor 7 are shown, but a plurality of them can be arranged.

  The elevator control device 20 includes a controller 21 that is a processor that controls operation of the entire elevator control device 20, and a timer 22. The controller 21 monitors a signal from the operation panel 6 and a signal from the human sensor 7 as input signals, and controls driving of the car-side door driving device 30 and the car driving device 31 based on the input signals. Specifically, the controller 21 transmits and receives signals to and from the operation panel 6 and the human sensor 7, and executes arithmetic processing based on the signals from the operation panel 6 and the human sensor 7, and based on the processing result, the car An opening / closing command (door opening command or door closing command) for opening / closing the car side door 5 is output to the side door driving device 30, and the car 4 is moved up and down with respect to the car driving device 31. Outputs a movement command.

  The car-side door drive device 30 opens and closes the car-side door 5 of the car 4 according to a door open command or a door close command. At this time, the landing side door 2 opens and closes in conjunction. The car-side door driving device 30 drives the car 4 to move up and down in accordance with a movement command (lifting command).

  In addition, after the car 4 has arrived at the landing hall 1, the controller 21 starts to receive a signal from the human sensor 7 with the car door 5 opened. Further, when the controller 21 receives a person detection signal from the human sensor 7 while outputting the door closing command to the car side door driving device 30, the controller 21 stops outputting the door closing command to the car side door driving device 30, A door open command is output to the car side door drive device 30, the door close operation of the car side door 5 is reversed, and the door open operation is performed. When the controller 21 receives a person detection signal from the human sensor 7, the controller 21 activates the timer 22, and after the timer 22 is activated, the person (passengers 12, 13, 14) is received from the human sensor 7, for example, when the person in the human sensor detection range 8, 9 does not move for a certain time due to standing or the like, and the human sensor 7 is a signal indicating that the person detection signal does not change for a certain period of time, the output of the door opening command to the car side door driving device 30 is stopped, and the door closing command is output to the car side door driving device 30 To do.

  When the human sensor 7 detects a person, the controller 21 reverses the door-closing operation of the car-side door 5 to make the door-opening operation, and at the same time, through the operation panel 6, a speaker (see FIG. It is dangerous to send an audio signal to the car-side door 5 and to reverse the door-closing operation of the car-side door 5 and to have a person (passenger) in the blind spot of the passenger operating the operation panel 6 and to perform the door-closing operation. By making an announcement from the speaker, it is possible to convey the contents of the announcement to passengers in the car 4.

  FIG. 3 is a flowchart for explaining processing of the elevator control system according to the embodiment of the present invention.

  In FIG. 3, the controller 21 determines whether the call registration button 3 of the landing hall 1 is operated and the car 4 is stopped at the landing hall 1 (S1). The controller 21 repeats this process until the car 4 stops at the landing hall 1. When the controller 21 determines that the car 4 is stopped at the landing hall 1, it outputs a door opening command to the car-side door driving device 30. Then, it is determined whether the car-side door 5 is in the open state (S2). The controller 21 repeats the processing from step S1 to step S2 until the car side door 5 is in the door open state, and when it is determined that the car side door 5 is in the door open state, the human sensor 7 is activated (S3). ).

  Next, the controller 21 determines whether or not there is a door closing command (S4). For example, the controller 21 determines whether the operation panel 6 is operated and a door closing command is input from the operation panel 6 or whether a door closing command is input from the operation panel 6 after a predetermined time has elapsed. This process is repeated until the door closing command is input, and when it is determined that the door closing command is given, it is determined whether the human sensor has detected a person (S5). In step S5, the controller 21 determines whether or not a person detection signal has been received from the human sensor 7. If no human detection signal is received from the human sensor 7, the controller 21 proceeds to the process of step S8 to detect the human sensor. When a person detection signal is received from 7, when a person (passenger) in the human sensor detection ranges 8 and 9 is detected, it is determined whether or not the target person (passenger) has been stopped for a certain time, for example, several seconds. (S6).

  If the controller 21 determines in step S6 that the target person (passenger) has stopped for a certain period of time, the controller 21 proceeds to the process of step S8. On the other hand, if the controller 21 determines in step S6 that the target person has not stopped for a certain period of time, that is, detects the movement of the target person and determines that the target person is, for example, a rush passenger 12, the door is closed. In order to reverse and reverse the door, the output of the door closing command is stopped with respect to the car-side door driving device 30, the door-opening command is output, and the car-side door 5 is brought into the door-opening state (S7). Thereafter, the controller 21 returns to step S4 and repeats the processes of steps S4 to S6.

  If it is determined in step S5 that the human sensor has not detected a person, or if it is determined in step S6 that the target person has stopped for a certain time, the controller 21 Door closing is permitted (S8), and a door closing command is output. As a result, the car-side door driving device 30 closes the car-side door 5 (S9).

  After the car-side door 5 is closed, the controller 21 stops the activation of the human sensor 7 (S10), and then outputs a movement command to the car driving device 31 to move the car 4 ( (Car movement) is started (S11), and the processing in this routine is terminated.

  According to the present embodiment, the car-side door 5 can be opened and closed while ensuring the safety of passengers. That is, when there is a rush passenger 12 entering from a direction in which the passenger 10 operating the operation panel 6 is blind and invisible, the human sensor 7 detects the rush passenger 12. Even when the car-side door 5 and the landing-side door 2 are closed, the door-closing operation of the car-side door 5 and the landing-side door 2 is reversed and the door-opening operation is performed. Safety can be ensured. By mounting the human sensor 7 on the back side of the control panel 6 of the car 4, it becomes unnecessary to mount the human sensor 7 in the landing hall 1 of each floor. Furthermore, since it is intended for persons in the area (human sensor detection ranges 8 and 9) that are blind spots from the operator (passenger) of the operation panel 6, it is intended for all persons moving in the hall 1, so in the hall 1 Even if there is a person who moves, if the human sensor 7 does not detect a person within the human sensor detection ranges 8 and 9, the door closing instruction from the operation panel 6 is valid, and the car side door 5 and the landing side It is possible to avoid the door 2 from being open, and to suppress the stress on the passenger who is about to get on the car 4 and leave.

  Further, when the human sensor 7 detects a person in the human sensor detection ranges 8 and 9 and the controller 21 reverses the door closing operation of the car side door 5 and opens the door, the operation panel 6 is operated. Because the operation panel operator (passenger) is alerted to the presence of a person (passenger) in the blind spot, or from the speaker in the car 4, the door operation is performed to the operation panel operator. It is possible to notify in advance that it is dangerous.

  In addition, this invention is not limited to above-described embodiment, Various modifications are included. For example, the human sensor 7 and the operation panel 6 can be configured by one each. The above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to one having all the described configurations. It is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

  Further, each of the above-described configurations, functions, and the like may be realized by hardware by designing a part or all of them with, for example, an integrated circuit. Further, each configuration, function, etc. described above may be realized by software by the processor interpreting and executing a program that realizes each function.
