Detailed Description
Hereinafter, embodiments of the present invention will be described based on the drawings.
Fig. 1 is a block diagram showing the 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 stack controller 10 and 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 lifted and lowered. Each of the number controllers 100 to 300 is connected to the stack 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 each of the flight controls 100 to 300 has the same configuration, the flight control 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 individual car controllers 100 to 300 to collectively control the individual car controllers 100 to 300, and includes: hall call detection unit 11, assignment determination unit 12, and 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 a building. When the hall button 20 is operated by the passenger, 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 allocation determination unit 12 and the standby determination unit 13. The allocation 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 numbers 1 to 3 is allocated as the car corresponding to the hall call, and outputs the determination result to each of the car controllers 100 to 300. At this time, the liquid crystal display device, the allocation determination unit 12 performs ventilation operation, for example, with the nearest hall (the nearest response car) the number machine whose completion flag is valid (number machine whose ventilation operation is completed) is assigned as the number machine 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 car 1 to 3 is to be placed on standby, 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 ventilator control unit 106, a standby time measurement timer 107, and a ventilation time measurement timer 108, and is configured as a control device for controlling the operation of the car 1.
The operation control unit 101 is connected to the safety circuit control unit 102, the car call detection unit 103, the load detection unit 104, the door opening/closing control unit 105, the ventilator control unit 106, the standby time measurement timer 107, and the ventilation time measurement timer 108, and is connected to a hoisting machine 121 disposed on the roof of the 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 up and down. The operation control unit 101 is connected to the allocation determination unit 12 and the standby determination unit 13 of the stack 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 interior of the car. The door 127 is configured as a door opening/closing device for opening/closing 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 allocation determination unit 12 and the standby determination unit 13 of the group controller 10, and controls the start and stop of the standby time measurement timer 107 and the ventilation time measurement timer 108 in response to the detection signal of the car call detection unit 103. 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 and the detection signal of the load detection unit 104, the determination results of the allocation 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 ventilator 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 cut-off circuit for cutting off the power supply to the motor incorporated in the hoisting machine 121 and a cut-off circuit for cutting off the power supply to the door motor 127.
When the destination floor button 124 in the car is operated by the 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 records the history of operating the hoisting machine 121 (the history of turning on and off the motor incorporated in the hoisting machine 121) as the operation 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 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=an average weight of each person (65 kg) ×a person×0.4, the operation control unit 101 determines that the inside of the car is dense due to passengers.
The door opening/closing control unit 105 takes in a door opening signal indicating that the door is open or a door closing signal indicating that the door is closed from a door switch 126 that detects the open/closed state of the 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 a door opening signal or a 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, and controls opening/closing of the door of the car.
When a command to control the operation of the ventilator 128 is received from the operation control unit 101, the ventilator control unit 106 controls the operation of the ventilator 126 in response to the received command.
After the operation of the car by the car call or hall call is performed (after the service of the car is completed), the operation control unit 101 determines whether or not the ventilation start condition is satisfied, and generates a command to control the operation of the ventilator 128 when the ventilation start condition is satisfied. At this time, the operation control unit 101 checks whether or not the predetermined time has elapsed in the no-call standby state, and whether or not the safety circuit 123 operates normally. For example, when there is no car call or hall call detected by the car call detection unit 103 and the driving of the motor built in the hoisting machine 121 is stopped, and the car is in a stopped state, that is, when there is no car call or 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 being in the no-call standby state in a log, and starts the standby time timer 107. When the measured value of the standby time timer 107 becomes equal to or greater than the predetermined value and the control result indicating that the safety circuit 123 is operating normally is obtained from the safety circuit control unit 102, the operation control unit 101 determines that the ventilation start conditions are all satisfied and generates a command to control the operation of the ventilator 128.
When the operation of the ventilator 128 is started, the operation control unit 101 sets a ventilation operation completion flag, which is operation record information of the ventilator 128, to be inactive, 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 (measured value) of the ventilation time measurement timer 108 to the allocation determination unit 12 and the standby determination unit 13. When the ventilation operation of the ventilator 128 is completed and the operation of the ventilator 128 is stopped, the operation control unit 101 stops the start of the ventilation time measurement timer 108, sets the ventilation operation completion flag from inactive to active, and outputs information on the value (measured value) of the ventilation time measurement timer 108 and information on the inactive ventilation operation completion flag to the allocation determination unit 12 and the standby determination unit 13.
Fig. 2 is a flowchart for explaining a process of the dial controller of the embodiment of the present invention. This process is always performed during the service period of the car. In fig. 2, the operation control unit 101 refers to a log recorded on the operation history of the hoisting machine 121, and determines whether or not the car (machine No. 1) is traveling by a car call (S201). When a negative (no) determination result is obtained in step S201, that is, when the car is not traveling by a car call, the operation control unit 101 repeats this process. On the other hand, when the affirmative (yes) determination result is obtained in step S201, that is, when the car is traveling by a car call, the operation control unit 101 acquires a 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).
When a negative determination result is obtained in step S202, that is, when 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, when the affirmative determination result is obtained in step S202, that is, when the car is traveling with a predetermined load detection value or more (when the car is traveling with a lot of passengers, the operation control unit 101 sets the ventilation operation completion flag to be inactive, and resets the value (measurement value) of the ventilation time measurement timer 108 (S203).
Next, the operation control unit 101 refers to a log in which the operation state of the car is recorded, and 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, when a predetermined time elapses in the no-call standby state, the operation control unit 101 repeats the processing in step S204. On the other hand, when an affirmative determination is made in step S204, that is, when a predetermined time has elapsed in the no-call standby state, the operation control unit 101 generates a command for performing the 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, for example, the safety circuit control unit 102 performs control of cutting off the power supply to the motor incorporated in the hoisting machine 121 with respect to the safety circuit 123, and when it is confirmed that the safety circuit 123 is reliably operated, outputs a control result indicating that the safety circuit 123 is reliably operated to the operation control unit 101. That is, the safety circuit control unit 102 performs a fault diagnosis of the safety circuit 123 that stops the driving of the hoisting machine 121 when the car is abnormal, and confirms whether or not the result of the diagnosis is in a normal state.
Next, the operation control unit 101 starts (starts) the ventilation time measurement timer 108 on condition that the safety circuit 123 is confirmed to be 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 ventilator 126 to the ventilator control unit 106, and opens the door to rotate the ventilator 128 (S207). At this time, the door opening/closing control unit 105 opens the door via the door motor 125, and the ventilator control unit 106 rotates the ventilator 126.
Next, the operation control unit 101 receives the determination result from the assignment determination unit 12, and determines whether or not the car is assigned to 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 a positive (yes) determination result is obtained in step S208, that is, if a hall call is not assigned to the car, the detection result of the car call detection unit 103 is acquired, and it is determined whether or not there is a car call for the car (S209).
When a negative (no) determination result is obtained in step S209, that is, when a car call is made to the car, the operation control unit 101 proceeds to the process of step S213, and when an affirmative (yes) determination result is obtained in step S209, that is, when no car call is made to the car, the measured value of the ventilation time measurement timer 108 is taken in, and it is determined whether or not the value (measured value) of the ventilation time measurement timer 108 is equal to or greater than a predetermined value (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 greater than a predetermined value.
When the value (measured value) of the ventilation time measurement timer 108 is a predetermined value, for example, when the ventilation time which is the measured value of the ventilation time measurement timer 108 is the ventilation operation completion time, the operation control unit 101 sets the ventilation operation completion flag from inactive to active, and stops the ventilation time measurement 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 ventilator 126 to the ventilator control unit 106, and closes the door to stop the ventilator 128 (S212). At this time, the door opening/closing control unit 105 closes the door via the door motor 125, and the ventilator control unit 106 stops the ventilator 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, when a negative (no) determination result is obtained in step S208 or step S209, the operation control unit 101 stops the ventilation time measurement timer 108 and resets the value (measurement value) of the ventilation time measurement 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 ventilator 126 to the ventilator control unit 106, and closes the door to stop the ventilator 128 (S214). At this time, the door opening/closing control unit 105 closes the door via the door motor 125, and the ventilator control unit 106 stops the ventilator 126. Then, in step S214, the operation control unit 101 executes processing corresponding to hall call or car call. For example, the operation control unit 101 performs a process of driving the hoisting machine 121 to move the car to the hall as a process corresponding to the hall call, and a process of driving the hoisting machine 121 to move the car to the destination floor as a process corresponding to the car call. Thereafter, the operation control unit 101 proceeds to the process of step S204, and repeats the processes of step S204 to step S214.
As a service of the car, after performing a process corresponding to a hall call or a car call, when a predetermined time elapses in a no-call standby state, the air exchange fan 128 is rotated for a predetermined time in a state where the door of the car is opened, whereby the interior of the car in a dense state due to passengers can be sufficiently ventilated. This can then provide a safe environment for passengers who utilize the car of the elevator.
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 service period 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). When it is determined that hall call is detected (yes), hall call detector 11 outputs a detection signal indicating that hall call is present to allocation determination unit 12, and when it is determined that hall call is not detected (no), it outputs a detection signal indicating that hall call is not present to standby determination unit 13.
When hall call is detected, the allocation determination unit 12 acquires information (valid or invalid information) of the ventilation operation completion flag and the measurement value of the ventilation time measurement timer 108 from the operation control unit 101 of each of the individual car controllers 100 to 300, it is determined whether or not there is a vehicle number for which the ventilation operation completion flag is valid (S302).
If the affirmative (yes) determination result is obtained in step S302, that is, if there is a valid ventilator of the ventilatory operation completion flag, the allocation determination unit 12 allocates, for example, the fastest responding ventilator among the ventilatory operation completion flag valid modems as the hall call modems (S303), and then returns to the process of step S301 to repeat the processes of steps S301 to S303.
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 air exchange operation completion flag is valid, the largest number of the ventilation time measurement timer 108 (measurement value) is assigned as the hall call number (S304), and the process returns to step S301, and the processes of steps S301 to S304 are repeated.
If hall call is not detected in step S301, the standby determination unit 13 acquires information (valid or invalid information) of the ventilation operation completion flag from the operation control unit 101 of each of the air-conditioning controllers 100 to 300, and determines whether or not there is an air-conditioning device for which the ventilation operation completion flag is valid (S305).
When the affirmative (yes) determination result is obtained in step S305, that is, when there is a ventilator for which the ventilation operation completion flag is valid, the standby determination unit 13 executes a process (S306) of making the ventilator for which the ventilation operation completion flag is valid standby at the standby layer, and thereafter returns to the process of step S301, and the processes of steps S301 to S306 are repeated. On the other hand, when a negative (no) determination result is obtained in step S305, that is, when no ventilation operation completion flag is valid, the standby determination unit 13 returns to the process of step S301, and repeats the processes of steps S301 to S306.
When the hall call is detected, the group controller 10 acquires information of a ventilation operation completion flag from each of the car controllers, sets the ventilation operation completion flag in each of the car controllers to be valid, and performs a process of assigning a car to be operated by the car controller to a car corresponding to the hall call. That is, when the hall call is detected, the group controller 10 assigns the nearest one of the machines (machines whose ventilation operation is completed) for which the ventilation operation completion flag is valid as the machine for which the hall call is to be responded.
When the hall call is detected, the group controller 10 acquires information of a ventilation operation completion flag from each of the car controllers, acquires a measurement value of a ventilation time of a ventilation operation by a ventilator from each of the car controllers when no ventilation operation completion flag is set to be valid, and performs a process of assigning a car to be operated by the car controller to a car corresponding to the hall call for a car controller whose measurement value of a ventilation time of a ventilation operation by a ventilator is the largest among the car controllers. That is, when a hall call is detected, the group controller 10 can assign a hall call-responsive car to which the ventilation time measurement timer has the largest value (measurement value) when no car has a ventilation operation completion flag.
When hall call is not detected, the group controller 10 acquires information of a ventilation operation completion flag from each of the car controllers, sets the ventilation operation completion flag in each of the car controllers to be valid, and performs a process of assigning a car to be operated by the car controller to a car corresponding to a standby of the standby floor. That is, when no hall call is detected, the group controller 10 can set the nearest responding one of the air-exchange operation completion flag valid (air-exchange operation completed) to standby at the standby level. In this case, when detecting a hall call, the group controller 10 can immediately respond to the hall call with a waiting machine at the standby floor as a machine for which the ventilation operation is completed.
