Abstract

<P>PROBLEM TO BE SOLVED: To provide a sensor power control system for an elevator for cutting the power supply to a passenger detection sensor if the detection operation of passengers getting in/getting off a car of the elevator is unnecessary. <P>SOLUTION: A main control unit acquires door operational state information including information on the opened/closed state of a door for opening/closing an entrance of an elevator car from, for example, an operation management system. The main control unit determines from the acquired information on the door operational state whether or not the door is in a door fully closed state (21-1), a door opening state (21-2), a door fully opened state (21-3) or a door closing state (21-4). When the main control unit determines that the door is in the door closing state (21-4), a power supply unit is turned on only during the door closing state (21-4), and the power is supplied to a passenger detection sensor to be operated. Thus, the power consumption of the passenger detection sensor can be suppressed. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

Description

  The present invention relates to a sensor power control system for an elevator that controls power supply to a sensor that detects a passenger existing near an entrance / exit of an elevator car.

Conventional sensors for detecting passengers between halls or doors have reduced the power consumption by slowing the light emission period of the element. However, since the passenger detection sensor is always turned on, power is consumed even when the detection operation is unnecessary.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of an elevator door system using an elevator door passenger detection sensor 4. FIG. 1 is a front view of an elevator door device viewed from a landing side. In FIG. 1, an elevator door 1, one landing door 2 (also called a landing door) attached to the elevator door, the other landing door 3 attached to the elevator door, and the upper end of the elevator door 1. The detection light 6 which consists of the emitted light 6a and the reflected light 6b for detecting the passenger detection sensor 4, the power supply part 5 of the passenger detection sensor 4, and the passenger between landings or doors is shown. The back of the elevator door 1 is a cab 1a.

  FIG. 2 is a block diagram showing a control circuit of the elevator door system using the passenger detection sensor 4 for the elevator door. As shown in FIG. 2, the passenger detection sensor 4 includes a sensor control unit 11, a transmitter 12, and a receiver 13. The passenger detection sensor 4 operates when power is supplied from the power supply unit 5. The emitted light 6a emitted from the transmitter 12 is received by the receiver 13 as reflected light 6b when reflected by the passenger 14 between the landings or doors.

(Passenger detection method)
When the emitted light 6 a transmitted from the transmitter 12 returns to the receiver 13 as reflected light 6 b due to the influence of the passenger 14, a passenger detection signal is output from the sensor control unit 11 to the main control unit 15. The main control unit 15 instructs a system (not shown) that controls the doors to reverse the landing doors 2 and 3 that are closed by the output of the passenger detection sensor 4.

  The power control operation of the passenger detection sensor for the elevator door in the case of FIG. 2 will be described with reference to FIG. FIG. 3A shows the state of the landing doors 2 and 3. Since the car door (also referred to as a car door) and the landing door move in conjunction with each other, FIG. 3A may be regarded as the state of the car door. The landing doors 2 and 3 take one of the following states. That is, from the door fully closed (21-1), the door open operation continuing from the fully closed state to the fully open state (21-2), the door fully open (21-3), from the door fully open state It is either during the door closing operation (21-4) in which the door closing operation is continued toward the fully closed state. FIG. 3B shows the on / off state of the power supply unit 5 that operates the passenger detection sensor 4. As shown in FIGS. 3 (a) and 3 (b), the power supply 5 is fully closed (21-1), during door opening (21-2), fully open (21-3), during door closing ( Regardless of 21-4), it is always on.

  In the method of FIG. 3, the passenger detection sensor 4 is also turned on even when the door is closed (21-1) or during the door opening operation (21-2), which is a door state that does not require the detection output of the passenger detection sensor 4. Therefore, wasteful power was consumed.

  Hereinafter, an elevator sensor power control system 100 that suppresses unnecessary power consumption of the passenger detection sensor 4 will be described with reference to FIGS. 4 to 9.

  FIG. 4 is a view corresponding to FIG. 1 and is a front view as seen from the landing side as in FIG. In FIG. 4, a main control unit 15 a having a function of controlling on / off of the power supply unit 5 is further added to FIG. 1.

  FIG. 5 is a schematic view corresponding to a plan view showing a state in which the landing side is looked down from the ceiling side of the car room 1a in FIG. FIG. 5 is a diagram for explaining the positional relationship between the car doors 1b and 1c (also called car doors), the landing doors 2 and 3, and the emitted light 6a. The emitted light 6a-1 shows an irradiation area where the emitted light 6a irradiates the floor of the hall as an image.

  FIG. 6 is a schematic view corresponding to a side view when viewed from the direction of the landing door 2 of the car room 1a of FIG. FIG. 6 is a diagram useful in explaining the positional relationship between the car door 1b, the landing door 2, and the emitted light 6a, and the location where the passenger detection sensor 4 is attached. As shown in FIG. 6, the passenger detection sensor 4 is located above the car door 1b. The passenger detection sensor 4 is attached to, for example, an attachment arm 1d fixed to a hanger plate (not shown) fixed to the upper end of the car door 1b. Further, as shown in FIG. 6, the launch light 6 a of the passenger detection sensor 4 is set to irradiate the landing door 2. Specifically, as described in the description of FIG. 9 to be described later, when the passenger detection sensor 4 is supplied with electric power, when the landing door 2 starts moving in the door opening direction from the door closing state, The landing door 2 can be detected by the reflected light 6 b reflected from the landing door 2 by the emitted light 6 a.

  FIG. 7 is a diagram corresponding to FIG. 2, and is a block diagram of an elevator sensor power control system 100 that suppresses power consumption of the passenger detection sensor 4. The configuration of FIG. 7 is the same as that of FIG. 2, except that the main control unit 15 a controls the supply of power to the passenger detection sensor 4 by turning the power supply unit 5 on and off. As shown in FIG. 7, the elevator sensor power control system 100 includes a passenger detection sensor 4 (sensor device), a main control unit 15 a (an example of a power supply control device), and a power supply unit 5.

  An operation in which the main control unit 15a controls on / off of the power supply unit 5 that supplies power to the passenger detection sensor 4 will be described with reference to FIG. In FIG. 7, when the main control unit 15 a “turns off” the power supply unit 5 of the passenger detection sensor 4, the passenger detection sensor 4 is turned off and the power consumption of the passenger detection sensor 4 becomes “0 (zero)”. .

(Description of operation)
The power control operation of the passenger detection sensor 4 by the main control unit 15a will be described with reference to FIG. FIG. 8 is a view corresponding to FIG. 3, FIG. 8A shows the state of the landing doors 2 and 3, and FIG. 8B shows the ON / OFF state of the power supply unit 5.

  In the state of the landing doors 2 and 3 that require the operation of the passenger detection sensor 4 (power ON state), the door closing operation is continued from the door fully open (21-3) to the door fully closed (21-1). The door is being closed (21-4). For this reason, only during the door closing operation (21-4), the main control unit 15a turns on the power supply unit 5 of the passenger detection sensor 4 to detect the passenger. Specifically, the main control unit 15a is in the states of the landing doors shown in FIG. 8, the door fully closed (21-1), the door opening operation (21-2), the door fully open (21-3), Information (door operation state information) is acquired during the door closing operation (21-4). The acquisition destination is, for example, an operation management system that controls the operation management of an elevator. That is, the main control unit 15a acquires each information on the car door from the door fully closed (21-1) to the door closing operation (21-4) from the operation management system. Since the landing door and the car door are interlocked with each other and the door is opened and closed, acquiring the door fully closed (21-1) to during the door closing operation (21-4) for each car door It is the same as getting the status. Alternatively, the acquisition device is not limited to the operation management system, and a detection device capable of detecting each state of the landing door (or car door) from the door fully closed (21-1) to the door closing operation (21-4). You may install and acquire from this detection apparatus. The acquisition destination is not particularly limited.

  As shown in FIG. 8, the main control unit 15a starts moving from the door open state (door fully open) to the door close direction based on the acquired door state (door operation state information) and opens the door closed state (door The period during the door closing operation (door closing operation period) until it becomes fully closed) is detected. Then, power is supplied to the passenger detection sensor 4 by turning on the power source 5 only during the detected door closing operation period.

  As shown in FIG. 8, by supplying power to the passenger detection sensor 4 only during the door closing operation (21-4), the method shown in FIG. 8 consumes less than 1/4 of the method shown in FIG. Can be lowered.

  In the method shown in FIG. 8, when the power supply unit 5 is turned on, it is unclear whether the passenger detection sensor 4 has started normal operation. For this reason, the door opening / closing operation may be performed in a state where the passenger detection sensor 4 is not operating normally. As a countermeasure, another example of the power control operation of the passenger detection sensor 4 will be described with reference to FIG.

  FIGS. 9A and 9B show “door state” and “power supply” as in FIGS. 8A and 8B. FIG. 9C shows the detection output of the passenger detection sensor 4 (when a landing door described later is detected).

  In FIG. 9, first, the main control unit 15a receives information (door operation state information) that the door has started the door opening operation from the door fully closed (21-1), for example, from the operation management system. When the main control unit 15a receives this information, that is, when the door starts the door opening operation from the fully closed state to the fully open state, the main control unit 15a turns on the power source unit 5 of the passenger detection sensor 4 and turns the passenger detection sensor 4 on. Make it work. When the passenger detection sensor 4 starts functioning, light is emitted from the transmitter 12. For example, as shown in FIGS. 4 and 5, the transmitter 12 is set so that the emitted light 6 a is reflected on the landing door 2 that has started the door opening operation for a certain period of time. The transmitted emission light 6 a returns to the receiver 13 as reflected light 6 b due to the influence of the landing door 2. The sensor control unit 11 detects the reflected light 6b and outputs a detection signal (23-2) to the main control unit 15a. The main control unit 15a (an example of a sensor state determination device) determines that the operation of the passenger detection sensor 4 is normal when the detection signal (23-2) is received. On the other hand, when the detection signal (23-2) is not received, the passenger detection sensor 4 is determined to be abnormal. In the case of FIG. 9, the main control unit 15a turns off the power supply unit 5 only when the door is fully closed (21-1).

  As shown in FIG. 9, when the passenger detection sensor 4 is supplied with electric power, for example, when the landing door 2 starts the door opening operation in the door opening direction from the door closing state, the passenger detection sensor 4 operates (moves). The starting landing door 2 can be detected. The main control unit 15a supplies power to the passenger detection sensor 4 when it is determined that the operation state of the landing door 2 specified from the information indicating the state of the door (door operation state information) is the door fully closed state. Stop. When the main control unit 15a determines that the operation state of the landing door 2 specified from the information indicating the door state is a state in which movement is started in the door opening direction from the fully closed door (21-1), the passenger detection sensor The power supply to 4 is started. The main control unit 15a (an example of a sensor state determination device) detects passengers based on the detection result by the passenger detection sensor 4 for the landing door 2 that starts moving in the door opening direction from the fully closed door (21-1). It is determined whether the detection sensor 4 is abnormal.

  As described above, according to the method shown in FIG. 9, it is possible to determine whether the detection operation of the passenger detection sensor 4 is normal or abnormal.

  Although the passenger detection sensor 4 is turned off, the same effect can be obtained by turning off the output (emitted light) of the transmitter that occupies most of the power consumption. That is, controlling the transmitter is an example, and the passenger detection sensor includes a plurality of sensor operation units such as a sensor control unit 11, a transmitter 12, and a receiver 13 that operate by receiving power supply. Alternatively, the main control unit 15a may control power supply to a preset sensor operation unit among the plurality of sensor operation units. In this case, the sensor operation unit whose power supply is controlled may be set based on the power consumption of the sensor operation unit.

  In the elevator sensor power control system 100 according to the first embodiment, the main control unit 15a turns on / off the power supply unit 5 in accordance with the state of the door, so that power consumption of the passenger detection sensor can be suppressed.

  In the elevator sensor power control system 100 according to the first embodiment, the main control unit 15a controls the power supply to the preset sensor operation unit, so that power consumption can be finely controlled.

  In the elevator sensor power control system 100 according to the first embodiment, the main control unit 15a controls the power supply to the sensor operation unit set based on the power consumption, and thus can effectively suppress the power consumption.

  In the elevator sensor power control system 100 according to the first embodiment, the main control unit 15a controls the power supply to the transmitter having a large power consumption, and thus can effectively suppress the power consumption.

  In the elevator sensor power control system 100 according to the first embodiment, the power supply unit 5 is turned on only during the door closing operation of the main control unit 15a, so that the power consumption of the passenger detection sensor can be suppressed.

  In the elevator sensor power control system 100 according to the first embodiment, when the door starts the door opening operation, the main control unit 15a turns on the power supply unit 5, and the passenger detection sensor 4 detects the door that has started the door opening operation. Since it did, in addition to the power consumption suppression of the passenger detection sensor 4, it can be checked easily whether the passenger detection sensor 4 operate | moves normally.

  In the first embodiment described above, in a system including a passenger detection sensor for detecting passengers between landings or doors, when it is not necessary to detect passengers, the passenger detection sensor is turned off. A sensor power control system for a vehicle has been described.

  In the first embodiment described above, when the door starts the door opening operation from the fully closed state to the fully open state, the passenger detection sensor is turned on, and the detection function of the passenger detection sensor is determined depending on the presence or absence of the detection output signal. An elevator sensor power control system characterized by determining whether or not is normal or abnormal has been described.
