Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing an overall configuration of an elevator according to an embodiment of the present invention. In FIG. 1, the elevator 1 is configured as an elevator system including a group controller 10, a unit controller 100, a unit controller 200, and a unit controller 300. The group controller 10 and each of the unit controllers 100 to 300 are arranged in a building (not shown) having a hoistway for raising and lowering a plurality of cars (not shown). Each unit controller 100 to 300 is connected to the group controller 10 via a network (not shown). The Unit 1 controller 100 controls the operation of the vehicle of the Unit 1, the Unit controller 200 controls the operation of the vehicle of the Unit 2, and the Unit controller 103 controls the operation of the vehicle of the Unit 3. Since the unit controllers 100 to 300 have the same configuration, the unit controller 100 will be mainly described below.

The group controller 10 is a control device that sends and receives information to and from each unit controller 100 to 300 to collectively control each unit controller 100 to 300, and is a hall call detection unit 11, an allocation determination unit 12, and a standby determination unit. 13 is provided. The hall call detection unit 11 is connected to a hall button 20 installed in an elevator hall (not shown) of a building. When the passenger operates the hall button 20, the hall call detection unit 11 detects that the hall button 20 has been operated, and outputs a detection signal indicating the hall call to the allocation determination unit 12 and the standby determination unit 13. The allocation determination unit 12 monitors the operating state of the car and the ventilation state of the car by the controllers 100 to 300 of each unit, and determines which of Units 1 to 3 is assigned to the unit that responds to the hall call. The determination result is output to each unit controller 100 to 300. At this time, the allocation determination unit 12 calls the hall, for example, the unit closest to the hall (the unit that can respond fastest) and the ventilation operation completion flag is turned on (the unit that has completed the ventilation operation). Assign to the corresponding machine. The standby determination unit 13 monitors the operating state of the car and the ventilation state of the car by the controllers 100 to 300 of each unit, determines which of Units 1 to 3 is to be made to stand by on the standby floor, and the determination result is obtained. Is output to each unit controller 100 to 300.

The unit controller 100 includes an operation control unit 101, a safety circuit control unit 102, a car call detection unit 103, a load detection unit 104, a door open / close control unit 105, a ventilation fan control unit 106, and a standby time measurement timer 107. It is a computer device provided with a ventilation time measurement timer 108, and is configured as a control device for controlling the operation of the vehicle of Unit 1.

The operation control unit 101 includes a safety circuit control unit 102, a car call detection unit 103, a load detection unit 104, a door open / close control unit 105, a ventilation fan control unit 106, a standby time measurement timer 107, and a ventilation time measurement timer. In addition to being connected to 108, it is connected to a hoist 121 arranged on the roof of the building and a display 122 arranged in the car and displaying information. The hoisting machine 121 is configured as a car car driving device that drives the car up and down. Further, the operation control unit 101 is connected to the allocation determination unit 12 and the standby determination unit 13 of the group controller 10.

The safety circuit 121 of the car (Unit 1) is connected to the safety circuit control unit 102, the destination floor button 124 in the car is connected to the car call detection unit 103, and the load detection unit 104 is connected to the ride. A load sensor 125 that detects the load acting on the car is connected, and the door open / close control unit 105 is connected to a door switch 126 that detects the opening / closing of the car door (door) and a door machine 127 that opens / closes the car door. Is connected, and a ventilation fan 128 that ventilates the inside of the car is connected to the ventilation fan control unit 106. The door machine 127 is configured as a door opening / closing device for opening / closing the door of the car.

The operation control unit 101 controls the operation of the car by transmitting / receiving information to / from the allocation determination unit 12 and the standby determination unit 13 of the group controller 10, and also responds to the detection signal of the car call detection unit 103 to control the car operation. Controls the start and stop of the standby time measurement timer 107 and the ventilation time measurement timer 108. Further, when the operation control unit 101 controls the operation of the car, the detection signal of the car call detection unit 103, the detection signal of the load detection unit 104, and the allocation determination unit 12 and the standby determination unit 13 of the group controller 10 Various commands are generated based on the determination result, and each generated command is output to the safety circuit control unit 102, the door open / close control unit 105, the ventilation fan control unit 106, or the hoisting machine 121.

The safety circuit control unit 102 controls the safety circuit 123 based on the command from the operation control unit 101, and outputs the control result to the operation control unit 101. The safety circuit 123 is composed of, for example, a cutoff circuit that cuts off the power supply of the motor built in the hoisting machine 121 and a cutoff circuit that cuts off the power supply of the door machine 127.

When the destination floor button 124 in the car is operated by a passenger, the car call detection unit 103 outputs a car call detection signal indicating the destination floor of the car to the operation control unit 101. At this time, the operation control unit 101 generates a command for moving the car to the destination floor, outputs the generated command to the hoisting machine 121, and has a history of operating the hoisting machine 121 (to the hoisting machine 121). The history of turning on / off the built-in motor) is recorded in the log as the driving history or running history of the car.

The load detection unit 104 outputs a load detection signal indicating a load detection value from the load sensor 125 that detects the load acting on the car to the operation control unit 101. At this time, when the load detection value by the load detection signal is equal to or more than the predetermined load detection value, the operation control unit 101 has, for example, that the load detection value is a predetermined value = average body weight per person (65 kg) × capacity × 0. If it is 4 or more, it is determined that the inside of the car is crowded by passengers.

The door open / close control unit 105 takes in a door open signal indicating that the door is open or a door close signal indicating that the door is closed from the door switch 126 that detects the open / closed state of the car door, and obtains a door open signal or a door open signal. The door closing signal is output to the operation control unit 101. The operation control unit 101 generates a command based on the door open signal or the door close signal from the door switch 126, and outputs the generated command to the door open / close control unit 105. The door opening / closing control unit 105 drives the door machine 127 in response to a command to control the opening / closing of the car door.

When the ventilation fan control unit 106 receives a command for controlling the operation of the ventilation fan 128 from the operation control unit 101, the ventilation fan control unit 106 controls the operation of the ventilation fan 126 in response to the received command.

The operation control unit 101 determines whether or not the ventilation start condition is satisfied after the car is operated by the car call or the hall call (after the car service is terminated), and the ventilation start condition is satisfied. If so, generate a command to control the operation of the ventilation fan 128. At this time, the operation control unit 101 confirms whether the safety circuit 123 operates normally after the callless standby state has elapsed for a predetermined time. For example, the operation control unit 101 does not have a car call by detection of the car call detection unit 103 and a hole call from the group controller 10, and the drive of the motor built in the hoist 121 is stopped, and the car is stopped. When the state is reached, that is, when there is no car call or hall call and the car is in the no-call standby state, which is the state in which the car is stopped, the state of the no-call standby state is recorded in the log. , The standby time timer 107 is activated. After that, when the measured value of the standby time timer 107 becomes equal to or more than a predetermined value and the safety circuit control unit 102 obtains a control result indicating that the safety circuit 123 operates normally, the operation control unit 101 sets the ventilation start condition. It is determined that all the conditions are satisfied, and a command to control the operation of the ventilation fan 128 is generated.

Further, when the operation of the ventilation fan 128 is started, the operation control unit 101 sets the ventilation operation completion flag, which is the operation record information of the ventilation fan 128, to off, and sets the value (timer value) of the ventilation time measurement timer 108. It resets and activates the ventilation time measurement timer 108. At this time, the operation control unit 101 outputs the information that the ventilation operation completion flag is off and the value (measured value) of the ventilation time measurement timer 108 to the allocation determination unit 12 and the standby determination unit 13. Further, when the ventilation operation by the ventilation fan 128 is completed and the operation of the ventilation fan 128 is stopped, the operation control unit 101 stops the activation of the ventilation time measurement timer 108 and sets the ventilation operation completion flag from off to on. , Information on the value (measured value) of the ventilation time measurement timer 108 and information on the ventilation operation completion flag being ON are output to the allocation determination unit 12 and the standby determination unit 13.

FIG. 2 is a flowchart for explaining the processing of the Unit controller according to the embodiment of the present invention. This process is always performed during the time of service by the car. In FIG. 2, the operation control unit 101 refers to a log for recording the operation history of the hoisting machine 121, and determines whether or not the car (Unit 1) is traveling by calling the car (S201). The operation control unit 101 repeats this process when a negative (NO) determination result is obtained in step S201, that is, when the vehicle has not been driven by calling the car. On the other hand, when the operation control unit 101 obtains a positive (YES) determination result in step S201, that is, when the vehicle is traveling by calling the car, the operation control unit 101 takes in the load detection signal from the load detection unit 104, and the car receives a load detection signal. It is determined whether or not the vehicle has traveled at a predetermined load detection value or more (S202).

When the operation control unit 101 obtains a negative determination result in step S202, that is, when the car is not traveling at a predetermined load detection value or more, the operation control unit 101 shifts to the process of step S201 and proceeds to the process of steps S201 to S202. Repeat the process of. On the other hand, when the operation control unit 101 obtains a positive determination result in step S202, that is, when the car is traveling at a predetermined load detection value or more (in a state where the car is crowded with many passengers). (When traveling), the ventilation operation completion flag is turned off, and the value (measured value) of the ventilation time measurement timer 108 is reset (S203).

Next, the operation control unit 101 refers to the log that records the operation state of the car, takes in the measured value of the standby time measurement timer 107, and determines whether or not the predetermined time has elapsed in the callless standby state. (S204). The operation control unit 101 repeats the process of step S204 until a negative determination result is obtained in step S204, that is, until a predetermined time elapses in the callless standby state. On the other hand, the operation control unit 101 issues a command for performing a failure check of the safety circuit 121 when a positive determination result is obtained in step S204, that is, on the condition that a predetermined time has elapsed in the callless standby state. Generated and output the generated command to the safety circuit control unit 102 (S205). As a result, the safety circuit control unit 102 controls the safety circuit 123 and outputs the control result to the operation control unit 101. At this time, the safety circuit control unit 102, for example, executes control for the safety circuit 123 to shut off the power supply of the motor built in the hoisting machine 121, and confirms that the safety circuit 123 has operated reliably. In this case, a control result indicating that the safety circuit 123 has been reliably operated is output to the operation control unit 101. That is, the safety circuit control unit 102 diagnoses whether or not there is a failure in the safety circuit 123 that stops the drive of the hoisting machine 121 when the car is abnormal, and confirms whether the diagnosis result is in the normal state. ..

Next, the operation control unit 101 starts (starts) the ventilation time measurement timer 108 on condition that the safety circuit 123 has been confirmed to have operated reliably (S206). Subsequently, the operation control unit 101 outputs a command for opening the door to the door open / close control unit 105, and outputs a command for rotating the ventilation fan 126 to the ventilation fan control unit 106 to open the door. , The ventilation fan 128 is rotated (S207). At this time, the door opening / closing control unit 105 opens the door via the door machine 125, and the ventilation fan control unit 106 rotates the ventilation fan 126.

Next, the operation control unit 101 takes in the determination result from the allocation determination unit 12 and determines whether or not the car is assigned to the hall call (S208). When the operation control unit 101 obtains a negative (NO) determination result in step S208, that is, when the car is assigned to the hall call, the operation control unit 101 shifts to the process of step S213 and affirms (YES) in step S208. ), That is, when the car is not assigned to the hall call, the detection result of the car call detection unit 103 is taken in, and it is determined whether or not there is a car call for the car. (S209).

When the operation control unit 101 obtains a negative (NO) determination result in step S209, that is, when there is a car call for the car, the operation control unit 101 shifts to the process of step S213 and affirms (YES) in step S209. When the judgment result of is obtained, that is, when there is no car call for the car, the measured value of the ventilation time measurement timer 108 is taken in, and the value (measured value) of the ventilation time measurement timer 108 is equal to or higher than the predetermined value. It is determined whether or not (S210). At this time, the operation control unit 101 takes in the measured value of the ventilation time measurement timer 108, and repeats this process until the value (measured value) of the ventilation time measurement timer 108 becomes equal to or more than a predetermined value.

When the value (measured value) of the ventilation time measurement timer 108 reaches a predetermined value, for example, when the ventilation time, which is the measurement value of the ventilation time measurement timer 108, reaches the ventilation operation completion time, the operation control unit 101 may perform the ventilation time measurement timer 108. The ventilation operation completion flag is set from off to on, and the ventilation time measurement timer 108 is stopped (S211). Subsequently, the operation control unit 101 outputs a command for closing the door to the door open / close control unit 105, and outputs a command for stopping the ventilation fan 126 to the ventilation fan control unit 106 to close the door and ventilate. The fan 128 is stopped (S212). At this time, the door opening / closing control unit 105 closes the door via the door machine 125, and the ventilation fan control unit 106 stops the ventilation fan 126. After that, the operation control unit 101 shifts to the process of step S201, and repeats the process of steps S201 to S212.

On the other hand, when the operation control unit 101 obtains a negative (NO) determination result in step S208 or step S209, the operation control unit 101 stops the ventilation time measurement timer 108 and resets the value (measured value) of the ventilation time measurement timer 108 (measured value). S213). Subsequently, the operation control unit 101 outputs a command for closing the door to the door open / close control unit 105 and outputs a command for stopping the ventilation fan 126 to the ventilation fan control unit 106 to close the door and ventilate. The fan 128 is stopped (S214). At this time, the door opening / closing control unit 105 closes the door via the door machine 125, and the ventilation fan control unit 106 stops the ventilation fan 126. Further, in step S214, the operation control unit 101 executes a process for responding to a hall call or a car call. For example, the operation control unit 101 drives the hoisting machine 121 as a process of responding to the hall call, executes a process of moving the car to the hall, and drives the hoisting machine 121 as a process of responding to the car call. Then, the process of moving the car to the destination floor is executed. After that, the operation control unit 101 shifts to the process of step S204, and repeats the processes of steps 204 to S214.

The unit controller 100 operates the ventilation fan 128 with the car door open when a predetermined time elapses in the no-call standby state after executing the hall call or the process of responding to the car call as a service by the car. By rotating the car for a predetermined time, the inside of the car, which was crowded with passengers, can be sufficiently ventilated. This makes it possible to provide a safe environment for passengers who subsequently use the elevator car.

FIG. 3 is a flowchart for explaining the processing of the group controller according to the embodiment of the present invention. This process is always performed during the time of service by the car. In FIG. 3, the hall call detection unit 11 of the group controller 10 takes in the output of the hole button 20 and determines whether or not the hall call is detected (S301). When it is determined that the hole call is detected (YES), the hole call detection unit 11 outputs a detection signal indicating that there is a hole call to the allocation determination unit 12, and determines that the hole call is not detected. In the case (NO), a detection signal indicating that there is no hole call is output to the standby determination unit 13.

When the hall call is detected, the allocation determination unit 12 outputs the information of the ventilation operation completion flag (on or off information) and the measured value of the ventilation time measurement timer 108 from the operation control unit 101 of each unit controller 100 to 300. It is determined whether or not there is a unit in which the intake and ventilation operation completion flag is turned on (S302).

When the allocation determination unit 12 obtains a positive (YES) determination result in step S302, that is, when there is a unit in which the ventilation operation completion flag is on, the allocation determination unit 12 is among the units in which the ventilation operation completion flag is on. For example, the unit that can respond fastest is assigned to the unit that calls the hall (S303), and then the process returns to the process of step S301, and the processes of steps S301 to S303 are repeated.

On the other hand, when the allocation determination unit 12 obtains a negative (NO) determination result in step S302, that is, when there is no unit for which the ventilation operation completion flag is turned on, the value (measured value) of the ventilation time measurement timer 108. Allocates the largest machine to the hall-calling machine (S304), then returns to the process of step S301, and repeats the process of steps S301 to S304.

When the hall call is not detected in step S301, the standby determination unit 13 takes in the ventilation operation completion flag information (on or off information) from the operation control unit 101 of each unit controller 100 to 300, and completes the ventilation operation. It is determined whether or not there is a unit whose flag is on (S305).

When the standby determination unit 13 obtains a positive (YES) determination result in step S305, that is, when there is a unit in which the ventilation operation completion flag is on, the standby determination unit 13 sets the unit in which the ventilation operation completion flag is on to the standby floor. (S306), the process returns to the process of step S301, and the processes of steps S301 to S306 are repeated. On the other hand, if the standby determination unit 13 obtains a negative (NO) determination result in step S305, that is, if there is no unit for which the ventilation operation completion flag is turned on, the standby determination unit 13 then returns to the process of step S301 and returns to the process of step S301. The process of S306 is repeated.

When the group controller 10 detects the hall call, the information of the ventilation operation completion flag is taken in from each unit controller, and this unit controller is compared with the unit controller in which the ventilation operation completion flag is set to ON among the unit units controllers. The process of allocating the car to be operated to the unit that responds to the hall call is executed. That is, when the group controller 10 detects a hall call, the unit having the fastest response among the units in which the ventilation operation completion flag is turned on (the unit in which the ventilation operation is completed) is set as the unit that responds to the hall call. Allocate.

Further, when the group controller 10 detects a hall call, it takes in the information of the ventilation operation completion flag from each unit controller, and when there is no unit controller in which the ventilation operation completion flag is set to ON in each unit controller. , The measurement value of the ventilation time by the ventilation operation of the ventilation fan is taken in from each unit controller, and the operation of this unit controller is performed for the unit controller where the measurement value of the ventilation time by the ventilation operation of the ventilation fan is the maximum among the unit controllers. Execute the process of allocating the target car to the unit that responds to the hall call. That is, when the group controller 10 detects the hall call, when there is no unit in which the ventilation operation completion flag is turned on, the group controller 10 responds to the hall call with the unit having the maximum value (measured value) of the ventilation time measurement timer. It can be assigned to the unit.

Further, when the group controller 10 does not detect the hall call, it takes in the information of the ventilation operation completion flag from each unit controller, and for the unit controller in which the ventilation operation completion flag is set to ON among the unit units controllers. , The process of allocating the car to be operated by this unit controller to the unit corresponding to the standby on the standby floor is executed. That is, when the group controller 10 does not detect the hall call, the group controller 10 waits on the standby floor for the unit having the fastest response among the units for which the ventilation operation completion flag is turned on (the unit for which the ventilation operation has been completed). Can be made to. In this case, when the group controller 10 detects the hall call, the unit that has been made to stand by on the standby floor can be immediately made to respond to the hall call as the unit for which the ventilation operation is completed.

FIG. 4 is a block diagram of the hardware of the computer that realizes the group controller or each unit controller. In FIG. 4, the controller system 5000 constituting the group controller 10 or each unit controller 100 to 300 is, for example, a computer device including a processor 5100, a memory 5200, a storage 5300, a network interface 5400, an input device 5500, and an output device 5600. It is composed of a computer), and each part is connected via a bus 5700.

The processor 5100 is composed of, for example, a CPU (Central Processing Unit) that collectively controls the operation of the entire device. The memory 5200 is composed of a storage medium such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The storage 5300 is composed of a storage device including, for example, a storage device such as a hard disk device, a semiconductor memory device, an optical disk device, a magneto-optical disk device, a magnetic tape device, and a flexible disk device. The network interface 5400 is configured to include a NIC (Network Interface Card) for connecting to a wireless LAN or a wired LAN. The input device 5500 is composed of a keyboard or a mouse, and the output device 5600 is composed of a display or a printer.

The storage 5300 stores various computer programs read by the processor 5100 into the memory 5200 and executed. For example, in the storage 5300 of the group controller 10, a hall call detection program that causes the processor 5100 to function as the hall call detection unit 11, an allocation determination program that causes the processor 5100 to function as the allocation determination unit 12, and a standby determination unit 13 for the processor 5100.

The storage 5300 can be configured as a storage unit for storing various information and data, and a log for recording the operating state of the car and a ventilation operation completion flag can be stored in this storage unit.

According to the embodiment, after the car is operated, the inside of the car can be ventilated when the ventilation start condition is satisfied. That is, as a service by the car, the ventilation fan 128 is rotated for a predetermined time with the car door open when a predetermined time elapses in the no-call standby state after the hall call or the operation in response to the car call is performed. By doing so, it is possible to sufficiently ventilate the inside of the car, which was crowded with passengers. This makes it possible to provide a safe environment for passengers who subsequently use the elevator car.
