Description

  Embodiments described herein relate generally to an elevator and an elevator operation method.

  The elevator connects the cage room and the weight with a rope, hangs the rope on a hoisting machine, and the hoisting machine rotates to raise and lower the car room. A frictional force with a constant friction coefficient acts between the hoisting machine and the rope, and the hoisting machine can wind up the rope by the presence of this frictional force.

  The mass is determined so that the weight is almost balanced with the cage room. However, especially in an elevator for a higher floor, it is not negligible that the weight of the rope is added to the cage room or the weight. When the cage room is in the vicinity of the uppermost floor or the lowermost floor, the weight of the rope breaks the balance between the weight and the weight of the cage room, and slipping occurs between the hoist and the rope.

  In this regard, a technique is used in which the bottom of the cage chamber is connected to the bottom of the weight, a compensation rope is provided so as to hang down in the hoistway, and the weight of the rope is offset by the weight of the compensation rope.

  However, depending on this technology, when a large number of passengers get in the cage compartment, the mass balance between the weight and the cage compartment is lost, slipping between the hoist and the rope occurs, and a lot of hoisting energy is required. Or

  Therefore, a technique has been proposed in which a liquid is injected into a tank provided in the lower part of the basket chamber or the liquid is sucked to maintain a balance between the mass of the weight and the cage chamber.

  However, with this technique, the weight of the hose that sends liquid to the tank becomes a new problem.

  The control unit 107 raises and lowers the basket room 101 to the designated destination floor. When the basket room 101 arrives at the destination floor, the engaging device 101B and the protrusion 104A are engaged. When the cage room side door 101A is opened and closed in this state, the landing side door 104 is driven and opened and closed.

  The floor camera 208 images passengers waiting in front of the landing-side door 104 on each floor, and the control unit 107 determines the number of waiting persons from the captured images.

  As will be described later with reference to FIGS. 3 and 4, the control unit 107 stores which of the first winder 202 and the second winder 203 winds the compensation rope 201 for each time zone. 302A is provided in the storage unit 302.

  FIG. 3 is a block diagram showing the configuration of the elevator 100. As shown in FIG. 3, the elevator 100 includes a weight sensor 204 and a first winder 202 provided in the basket room 101, a second winder provided in the weight 103, a control unit 107, a floor camera 208, and the like. .

  The control unit 107 includes a main control unit 301 that is an arithmetic device, and a storage unit 302 that stores information.

  The storage unit 302 stores a control table 302A.

  FIG. 4 is a diagram showing the data structure of the control table 203A. As illustrated in FIG. 4, the control table 203 </ b> A includes a “start time” that is a time to start control, an “end time” that is a time to end control, and a winder that winds the compensation rope 201. "Winding machine that performs winding".

  In the example of each data, the start time is “8:30”, the end time is “10:00”, and the winder that performs winding is “second winder”.

(Control by time)
The control table 302A indicates that the first winder 202 is wound around the compensation rope 201 during the busy period when the elevator is busy, and the second winder 203 is wound around the compensation rope 201 during the busy period when the elevator is busy. Which of the first winder and the second winder winds the compensation rope 201 is stored.

  The control unit 107 reads the time from the clock, refers to the control table 302A based on the read time, and controls the winding direction of the compensation rope 201.

(Control based on output of weight sensor 204)
The control unit 107 determines that a load greater than or equal to the threshold is applied to the basket room 101 based on the output of the weight sensor 204 during the off-season, that is, when the compensation rope 201 is wound around the first winder 202. In this case, the compensation rope 201 is sent out from the first winder 202 and the second winder 203 is controlled to wind.

(Control of alarm threshold)
In the busy period, that is, when the compensation rope 201 is wound around the second winder 203, the control unit 107 outputs a load over the first threshold value based on the output of the weight sensor 204. If it is determined that has been added to the basket room 101, it sounds.

  When the compensation rope 201 is wound around the first winder 202, the control unit 107 outputs an alarm indicating an overweight based on the output of the weight sensor 204 during the off-season, that is, when the compensation rope 201 is wound around the first winder 202. If it is determined that a load greater than or equal to the second threshold value has been applied to the basket chamber 101, it sounds.

  In other words, the control unit 107 sets the alarm threshold value so that the alarm is sounded even when the weight is lighter than the first threshold value when the compensation rope 201 is wound around the first winder 202. To change.

(Control by floor waiting number)
The control unit 107 detects the number of people waiting on each floor based on the output of the floor camera 208. For example, the control unit 107 detects the number of waiting persons by counting the number of faces using a known face recognition algorithm.

  When the control unit 107 determines that the number of people exceeding the threshold is waiting on the floor during the off-season, that is, when the compensation rope 201 is wound around the first winding machine 202, the control side 107 on the floor side Before the door 104 is opened, the compensation rope 201 is sent out from the first winder 202 and controlled to be wound up by the second winder 203.

  As described above, the elevator 100 according to the present embodiment includes the cage room 101, the weight 103, the rope 106 that lifts the cage room 101 and the weight 103, the hoisting machine 102 that winds the rope 106, and the basket room 101. The hoistway 110 that moves up and down, the cage chamber 101 and the weight 103 are connected to each other, and the compensation rope 201 that is provided so as to hang down in the hoistway 110 and the bottom portion of the cage chamber 101, The first winder 202 to be sent out, the second winder 203 which is provided at the bottom of the weight 103 and takes up or winds the compensation rope 201, and the first winder 202 and the second winder 203 are placed in the basket chamber. And a control unit 107 that controls the mass balance between the mass 101 and the weight 103.

  Therefore, even when installed in a high-rise building, the weight balance between the weight 103 and the cage room 101 can be maintained even when the passenger is lifted. Therefore, the hoisting machine 102 and the rope 106 do not slip, and the mass ratio is balanced between the weight 103 and the cage room 101, so that the elevator can be operated with less energy.
