Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a structural diagram showing an overall structure of an elevator according to an embodiment of the present invention. In fig. 1, an elevator 1 is configured as an elevator system including a group controller 10, a car controller 100, a car controller 200, and a car controller 300. The group controller 10 and each of the car controllers 100 to 300 are respectively disposed in a building (not shown) having a hoistway in which a plurality of cars (not shown) are raised and lowered. The respective car controllers 100 to 300 are connected to the group controller 10 via a network (not shown). The car controller 100 controls the operation of the car 1, the car controller 200 controls the operation of the car 2, and the car controller 103 controls the operation of the car 3. Since the respective machine controllers 100 to 300 have the same configuration, the machine controller 100 will be mainly described below.
The group controller 10 is a control device that performs transmission and reception of information with each of the car controllers 100 to 300 to collectively control each of the car controllers 100 to 300, and includes: a hall call detection unit 11, an assignment determination unit 12, and a standby determination unit 13. The hall call detection unit 11 is connected to a hall button 20 provided in an elevator hall (not shown) of the building. When the passenger operates the hall button 20, the hall call detection unit 11 detects that the hall button 20 is operated, and outputs a detection signal indicating a hall call to the assignment determination unit 12 and the standby determination unit 13. The assignment determination unit 12 monitors the operation state of the car and the ventilation state of the car of each of the car controllers 100 to 300, determines which of the car nos. 1 to 3 is assigned as the car corresponding to the hall call, and outputs the determination result to each of the car controllers 100 to 300. In this case, the assignment determination unit 12 assigns, for example, the car closest to the hall (car that can respond most quickly) and whose ventilation operation completion flag is valid (car whose ventilation operation is completed) as the car corresponding to the hall call. The standby determination unit 13 monitors the operation state of the car and the ventilation state of the car of each of the car controllers 100 to 300, determines which of the 1 st to 3 rd machines is to be made to stand by at the standby floor, and outputs the determination result to each of the car controllers 100 to 300.
The car controller 100 is a computer device including an operation control unit 101, a safety circuit control unit 102, a car call detection unit 103, a load detection unit 104, a door opening/closing control unit 105, a ventilation fan control unit 106, a standby time measurement timer 107, and a ventilation time measurement timer 108, and is configured as a control device that controls the operation of the car 1.
The operation control unit 101 is connected to a safety circuit control unit 102, a car call detection unit 103, a load detection unit 104, a door opening/closing control unit 105, a ventilation fan control unit 106, a standby time measuring timer 107, and a ventilation time measuring timer 108, and is also connected to a hoisting machine 121 disposed on the roof of a building and a display 122 disposed in the car and displaying information. The hoisting machine 121 is configured as a car driving device that drives the car to ascend and descend. The operation control unit 101 is connected to the assignment determination unit 12 and the standby determination unit 13 of the group controller 10.
The safety circuit control unit 102 is connected to a safety circuit 121 of a car (machine No. 1), the car call detection unit 103 is connected to a destination floor button 124 in the car, the load detection unit 104 is connected to a load sensor 125 that detects a load acting on the car, the door opening/closing control unit 105 is connected to a door switch 126 that detects opening/closing of a door (door) of the car and a door motor 127 that drives opening/closing of the door of the car, and the ventilation fan control unit 106 is connected to a ventilation fan 128 that ventilates the inside of the car. The door operator 127 is a door opening/closing device that opens and closes a door of the car.
The operation control unit 101 controls the operation of the car by transmitting and receiving information to and from the assignment determination unit 12 and the standby determination unit 13 of the group controller 10, controls the operation of the car in response to the detection signal of the car call detection unit 103, and controls the start and stop of the standby time measurement timer 107 and the ventilation time measurement timer 108. When controlling the operation of the car, the operation control unit 101 generates various commands based on the detection signal of the car call detection unit 103, the detection signal of the load detection unit 104, and the determination results of the assignment determination unit 12 and the standby determination unit 13 of the group controller 10, and outputs the generated commands to the safety circuit control unit 102, the door opening/closing 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 a command from the operation control unit 101, and outputs a control result to the operation control unit 101. The safety circuit 123 is constituted by, for example, a power cutoff circuit that cuts off the power supply of the motor built in the hoisting machine 121, and a power cutoff circuit that cuts off the power supply of the gantry crane 127.
When the passenger operates the destination button 124 in the car, the car call detection unit 103 outputs a car call detection signal indicating the destination 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 records the history of operating the hoisting machine 121 (history of turning on and off the motor built in the hoisting machine 121) in the log as the operation history or the travel history of the car.
The load detection unit 104 outputs a load detection signal indicating a load detection value from a load sensor 125 to the operation control unit 101, and the load sensor 125 detects a load acting on the car. At this time, when the load detection value based on the load detection signal is equal to or greater than a predetermined load detection value, for example, when the load detection value is equal to or greater than a predetermined value, such as an average body weight (65kg) × fixed person × 0.4 per person, the operation control unit 101 determines that the interior of the car is in a dense state due to passengers.
The door opening/closing control unit 105 takes in a door opening signal indicating that a door is opened or a door closing signal indicating that the door is closed from a door switch 126 that detects an open/close state of a door of the car, and outputs the door opening signal or the door closing signal to the operation control unit 101. The operation control unit 101 generates a command based on the door opening signal or the door closing signal from the door switch 126, and outputs the generated command to the door opening/closing control unit 105. The door opening/closing control unit 105 drives the door motor 127 in response to the command to control the opening/closing of the car door.
When receiving a command to control 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 operation of the car is performed based on the car call or the hall call (after the service of the car is completed), and generates a command for controlling the operation of the ventilation fan 128 when the ventilation start condition is satisfied. At this time, the operation control unit 101 checks whether or not a predetermined time has elapsed in the no-call standby state, and whether or not the safety circuit 123 is operating normally. For example, when the drive of the motor built in the hoisting machine 121 is stopped and the car is in a stopped state without the car call detected by the car call detection unit 103 and the hall call from the group controller 10, that is, when there is no car call and hall call and the car is in a stopped state, that is, in a no-call standby state, the operation control unit 101 records the state of the no-call standby state in a log and starts the standby time timer 107. Thereafter, when the measurement value of the standby time timer 107 becomes equal to or greater than the predetermined value and the safety circuit control unit 102 obtains the control result indicating the normal operation of the safety circuit 123, the operation control unit 101 determines that all of the ventilation start conditions are satisfied and generates a command for controlling the operation of the ventilation fan 128.
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 be invalid, resets the value (timer value) of the ventilation time measurement timer 108, and starts the ventilation time measurement timer 108. At this time, the operation control unit 101 outputs information indicating that the ventilation operation completion flag is invalid and the value (measurement value) of the ventilation time measurement timer 108 to the assignment determination unit 12 and the standby determination unit 13. When the ventilation fan 128 stops operating after the ventilation operation of the ventilation fan 128 is completed, the operation control unit 101 stops the start of the ventilation time measurement timer 108, sets the ventilation operation completion flag from invalid to valid, and outputs information on the value (measured value) of the ventilation time measurement timer 108 and information on the invalidity of the ventilation operation completion flag to the assignment determination unit 12 and the standby determination unit 13.
Fig. 2 is a flowchart for explaining the processing of the car controller of the embodiment of the present invention. This process is always performed during the time period of service of the car. In fig. 2, the operation control unit 101 refers to a log that records the operation history of the hoisting machine 121, and determines whether or not the car (machine No. 1) is traveling due to a car call (S201). When a negative (no) determination result is obtained in step S201, that is, when the vehicle is not traveling due to a car call, the operation control unit 101 repeats the above processing. On the other hand, if an affirmative (yes) determination result is obtained in step S201, that is, if the car is traveling due to a car call, the operation control unit 101 takes in the load detection signal from the load detection unit 104 and determines whether or not the car is traveling at or above a predetermined load detection value (S202).
If a negative determination result is obtained in step S202, that is, if the car is not traveling at or above the predetermined load detection value, the operation control unit 101 proceeds to the process of step S201 and repeats the processes of steps S201 to S202. On the other hand, if an affirmative determination is obtained in step S202, that is, if the car is traveling at or above the predetermined load detection value (if the car is traveling in a state of being crowded with many passengers), the operation control unit 101 sets the ventilation operation completion flag to be invalid, and resets the value (measurement value) of the ventilation time measurement timer 108 (S203).
Next, the operation control unit 101 refers to the log in which the operation state of the car is recorded, takes in the measurement value of the standby time measurement timer 107, and determines whether or not a predetermined time has elapsed in the no-call standby state (S204). When a negative determination result is obtained in step S204, that is, until a predetermined time elapses in the call waiting state, the operation control unit 101 repeats the process of step S204. On the other hand, if an affirmative determination is obtained in step S204, that is, if a predetermined time has elapsed in the no-call standby state, the operation control unit 101 generates a command for performing a failure check of the safety circuit 121, and outputs the generated command to the safety circuit control unit 102 (S205). Thereby, 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 executes control for shutting off the power supply to the motor incorporated in the hoisting machine 121, for example, with respect to the safety circuit 123, and outputs a control result indicating that the safety circuit 123 has reliably operated to the operation control unit 101 when it is confirmed that the safety circuit 123 has reliably operated. That is, the safety circuit control unit 102 diagnoses whether or not there is a failure in the safety circuit 123 that stops the driving of the hoisting machine 121 in the case of an abnormal car, and checks whether or not the result of the diagnosis is a normal state.
Next, the operation control unit 101 starts (starts) the ventilation time measurement timer 108 on condition that it is confirmed that the safety circuit 123 has reliably operated (S206). Next, the operation control unit 101 outputs a command for opening the door to the door opening/closing control unit 105, and outputs a command for rotating the ventilation fan 126 to the ventilation fan control unit 106, thereby opening the door and rotating the ventilation fan 128 (S207). At this time, the door opening/closing control unit 105 opens the door via the door operator 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 assignment determination unit 12, and determines whether or not a car is assigned a hall call (S208). If a negative (no) determination result is obtained in step S208, that is, if a hall call is assigned to the car, the operation control unit 101 proceeds to the process of step S213, and if an affirmative (yes) determination result is obtained in step S208, that is, if a hall call is not assigned to the car, the operation control unit takes in the detection result of the car call detection unit 103 and determines whether or not a car call is made to the car (S209).
If a negative (no) determination result is obtained in step S209, that is, if there is a car call to the car, the operation control unit 101 proceeds to the process of step S213, and if an affirmative (yes) determination result is obtained in step S209, that is, if there is no car call to the car, the operation control unit takes in the measurement value of the ventilation time measuring timer 108 and determines whether or not the value (measurement value) of the ventilation time measuring timer 108 is equal to or greater than a predetermined value (S210). At this time, the operation control unit 101 takes in the measurement value of the ventilation time measuring timer 108, and repeats this process until the value (measurement value) of the ventilation time measuring timer 108 becomes equal to or greater than a predetermined value.
When the value (measured value) of the ventilation time measuring timer 108 is a predetermined value, for example, when the ventilation time, which is the measured value of the ventilation time measuring timer 108, is the ventilation operation completion time, the operation control unit 101 sets the ventilation operation completion flag from off to on, and stops the ventilation time measuring timer 108 (S211). Next, the operation control unit 101 outputs a command for closing the door to the door opening/closing control unit 105, and outputs a command for stopping the ventilation fan 126 to the ventilation fan control unit 106, and closes the door to stop the ventilation fan 128 (S212). At this time, the door opening/closing control unit 105 closes the door via the door operator 125, and the ventilation fan control unit 106 stops the ventilation fan 126. Thereafter, the operation control unit 101 proceeds to the process of step S201, and repeats the processes of steps S201 to S212.
On the other hand, if a negative (no) determination result is obtained in step S208 or step S209, the operation control unit 101 stops the ventilation time measuring timer 108 and resets the value (measurement value) of the ventilation time measuring timer 108 (S213). Next, the operation control unit 101 outputs a command for closing the door to the door opening/closing control unit 105, and outputs a command for stopping the ventilation fan 126 to the ventilation fan control unit 106, and closes the door to stop the ventilation fan 128 (S214). At this time, the door opening/closing control unit 105 closes the door via the door operator 125, and the ventilation fan control unit 106 stops the ventilation fan 126. Then, in step S214, the operation control unit 101 executes processing corresponding to a hall call or a car call. For example, the operation control unit 101 performs a process of driving the hoisting machine 121 to move the car to the lobby as a process corresponding to a hall call, and performs a process of driving the hoisting machine 121 to move the car to the destination floor as a process corresponding to a car call. Thereafter, the operation control unit 101 shifts to the process of step S204, and repeats the processes of step S204 to step S214.
When a predetermined time has elapsed in the no call standby state after the car service is performed in response to the hall call or the car call, the car controller 100 can sufficiently ventilate the interior of the car densely populated with passengers by rotating the ventilation fan 128 for the predetermined time in a state where the doors of the car are opened. This makes it possible to provide a safe environment for passengers who use the elevator car.
Fig. 3 is a flowchart for explaining the processing of the group controller of the embodiment of the present invention. This process is always performed during the time period of service of the car. In fig. 3, the hall call detection section 11 of the group controller 10 takes in the output of the hall button 20 and determines whether or not a hall call is detected (S301). The hall call detection unit 11 outputs a detection signal indicating that a hall call is present to the assignment determination unit 12 when it is determined that a hall call is detected (yes), and outputs a detection signal indicating that no hall call is present to the standby determination unit 13 when it is determined that a hall call is not detected (no).
When a hall call is detected, the assignment determination unit 12 takes in information of the ventilation operation completion flag (valid or invalid information) and the measurement value of the ventilation time measurement timer 108 from the operation control unit 101 of each of the car controllers 100 to 300, and determines whether or not there is a car with the ventilation operation completion flag valid (S302).
When the affirmative (yes) determination result is obtained in step S302, that is, when there are any car with the ventilation operation completion flag being valid, the assignment determination unit 12 assigns, for example, the car that can respond most quickly among the cars with the ventilation operation completion flag being valid as the car for hall call (S303), and then returns to the processing of step S301, and repeats the processing of steps S301 to S303.
On the other hand, when a negative (no) determination result is obtained in step S302, that is, when there is no car whose ventilation operation completion flag is valid, the assignment determination unit 12 assigns the car whose value (measurement value) of the ventilation time measurement timer 108 is the largest as the car called by the hall call (S304), and then returns to the process of step S301, and repeats the processes of steps S301 to S304.
When the hall call is not detected in step S301, the standby determination unit 13 acquires information of the ventilation operation completion flag (valid or invalid information) from the operation control unit 101 of each of the car controllers 100 to 300, and determines whether or not there is a car whose ventilation operation completion flag is valid (S305).
When an affirmative (yes) determination result is obtained in step S305, that is, when there is a car whose ventilation operation completion flag is active, the standby determination unit 13 executes a process of making the car whose ventilation operation completion flag is active stand by at the standby floor (S306), and then returns to the process of step S301, and repeats the processes of steps S301 to S306. On the other hand, when a negative (no) determination result is obtained in step S305, that is, when there is no car with the ventilation operation completion flag being on, the standby determination unit 13 returns to the process of step S301, and repeats the processes of steps S301 to S306.
When a hall call is detected, the group controller 10 takes in information of the ventilation operation completion flag from each car controller, and executes processing for assigning the car to be operated by the car controller to the car corresponding to the hall call, for the car controller whose ventilation operation completion flag is set to be valid. That is, when the hall call is detected, the group controller 10 assigns the car that responds the fastest among the cars whose ventilation operation completion flag is valid (the cars whose ventilation operation is completed) as the car that responds to the hall call.
When a hall call is detected, the group controller 10 takes in information of the ventilation operation completion flag from each car controller, and when there is no car controller whose ventilation operation completion flag is set to be valid, takes in a measured value of the ventilation time by the ventilation operation of the ventilation fan from each car controller, and executes processing for allocating the car to be operated by the car controller to the car corresponding to the hall call, for the car controller whose measured value of the ventilation time by the ventilation operation of the ventilation fan is the largest among the car controllers. That is, when the hall call is detected and there is no car whose ventilation operation completion flag is valid, the group controller 10 can assign the car whose ventilation time measurement timer value (measurement value) is the largest as the car that responded to the hall call.
When the hall call is not detected, the group controller 10 acquires information of the ventilation operation completion flag from each car controller, and executes processing for assigning the car to be operated by the car controller to the car corresponding to the standby floor with respect to the car controller whose ventilation operation completion flag is set to be valid. That is, the group controller 10 can cause the car with the fastest response among the cars with the ventilation operation completion flag being valid (the car with the ventilation operation completed) to stand by at the standby floor when the hall call is not detected. In this case, when the hall call is detected, the group controller 10 can immediately respond to the hall call with the car waiting at the standby floor as the car whose ventilation operation is completed.
