Definitions
- the present invention relates to an elevator control device having a function of monitoring the presence or absence of an abnormality in brake torque.
- Patent Document 1 Japanese Patent Application Laid-Open No. 247383
- the present invention has been made to solve the above-described problems, and can perform more appropriate elevator control by distinguishing between a normal time and a disaster in response to a brake torque abnormality. It is an object to obtain an elevator control device that can
- An elevator control device includes a control device main body that controls the operation of a force and monitors the presence or absence of an abnormality in the brake torque of a brake device that brakes the running of the car. If an abnormality in brake torque is detected when the force is stopped, it is determined whether the operation is controlled during a disaster. If the operation is controlled during a disaster, the door is allowed to open. Stop opening.
- FIG. 1 is a configuration diagram showing an elevator apparatus according to Embodiment 1 of the present invention.
- FIG. 2 is a flowchart showing an operation of the elevator control device of FIG. 1 when the car is stopped.
- FIG. 1 is a configuration diagram showing an elevator apparatus according to Embodiment 1 of the present invention.
- the car 1 and the counterweight 2 are suspended in the hoistway by the main rope 3 and are raised and lowered by the driving force of the lifting machine 4.
- the lifting machine 4 has a drive sheave around which the main rope 3 is wound, a motor that rotates the drive sheave, and a brake device that brakes the rotation of the drive sheave.
- the operation of the force 1 is controlled by an elevator control device including the control device body 5. That is, the motor and brake device of the lifting machine 4 are controlled by an elevator control device.
- the control device body 5 is connected to a monitoring center 8 installed in a remote place via a notification device 6 and a general public line network 7. In the unlikely event that an abnormality occurs in the elevator device, the abnormality is reported from the control device body 5 to the monitoring center 8 via the reporting device 6 and the general public network 7.
- the control device body 5 includes operation control means 9, brake torque check means 10, disaster control operation means 11, door opening / closing determination means 12, terminal floor traveling means 13 and reporting means 14. .
- the operation control means 9 controls the overall operation of the elevator apparatus.
- the brake torque check means 10 monitors whether there is any abnormality in the brake torque of the lifting device 4 by, for example, monitoring the motor current value.
- the disaster control operation means 11 selects and executes the disaster control operation according to the detection signal of a disaster such as an earthquake or a fire. In disaster control operation, Force 1 is moved to the nearest floor or a preset evacuation floor and stopped.
- the door open / close determining means 12 determines whether door opening / closing is permitted when the force 1 stops at the stop floor.
- the terminal floor traveling means 13 causes the car 1 to travel to the terminal floor and pause.
- the reporting unit 14 generates an abnormality detection signal and outputs it to the reporting device 6.
- operation control means 9, brake torque check means 10, disaster control operation means 11 The door opening / closing judgment means 12, the terminal floor traveling means 13 and the reporting means 14 are realized by software. That is, the control device main body 5 is composed of a computer having an arithmetic processing unit (CPU), a storage unit (ROM, RAM, node disk, etc.) and a signal input / output unit. That is, the function of the control device body 5 is realized by a computer. In the storage unit, programs for realizing the functions of the operation control means 9, the brake torque check means 10, the disaster control operation means 11, the door open / close determination means 12, the terminal floor traveling means 13 and the reporting means 14 are stored. Stored.
- FIG. 2 is a flowchart showing the operation of the control device body 5 of FIG. 1 when the car is stopped.
- the operation in Fig. 2 starts when car 1 starts to decelerate.
- the control device main body 5 monitors whether the car 1 has entered the openable area (door zone) (step Sl).
- the door opening operation is temporarily blocked (step S2), and whether the force of the cage 1 is stopped is monitored (step S3).
- step S4 it is checked whether there is an abnormality in the brake torque, that is, whether there is a torque drop. If the brake torque is normal, the car door and the landing door are opened (step S5), and the process is terminated. If an abnormality in the brake torque is detected, it is checked whether disaster control operation has been selected (step S6). If disaster control operation has been selected, the power door and landing door are opened (step S5), and the process is terminated.
- step S7 the car 1 is driven to the terminal floor.
- the load on the force 1 side is larger than the load on the counterweight 2 side, it is preferable to move the force 1 to the lower terminal floor.
- the load on the counterweight 2 side is larger than the load on the car 1 side, it is preferable to move the car 1 to the upper terminal floor.
- step S8 When traveling to the terminal floor of the force 1 is started, it is monitored whether or not the force 1 has entered the openable region (step S8).
- the door opening operation is temporarily stopped (step S9), and it is monitored whether the cage 1 has stopped (step S10).
- step S11 When the force 1 stops, it is checked again whether there is an abnormality in the brake torque (step S11). If an abnormality in brake torque continues to be detected, it is confirmed again whether or not disaster control operation has been selected (step S12).
- step S13 when the brake torque has returned to normal, and when an abnormality in the brake torque is detected again, but the disaster control operation is selected while the car 1 travels to the terminal floor. Opens the force door and the landing door, closes the car door and the landing door after a predetermined time, and turns off the lights in the car 1 (step S13). Then, after reporting to the monitoring center 8 (step S14), the car 1 is continuously disabled until the maintenance staff releases it (step S15), and the process is terminated. However, if the car 1 is in the door openable area and the door open button in the car 1 is operated, the car door and the landing door are opened for a predetermined time.
- step S16 if an abnormality in the brake torque is still detected and the vehicle is in normal operation, the door-opening operation is continuously prevented (step S16), and the alarm is sent to the monitoring center 8 (step S16).
- step S17 the passenger is kept locked in the car 1 (Step S18), and the process is terminated. In this state, the operation of the door open button in the car 1 will not be accepted until maintenance personnel check it and confirm safety.
- an elevator control device if an abnormality in brake torque is detected when the car 1 is stopped, it is determined whether or not the operation is controlled during a disaster, and the door is opened if the operation is controlled during a disaster. Permits and prevents the door from opening during normal operation.In the event of a disaster, priority is given to evacuation by preventing passengers from being trapped in the car 1, and during normal times the door is closed and the brake torque remains abnormal. Passengers can be prevented from getting in and out of car 1. In other words, it is possible to perform more appropriate elevator control by distinguishing between normal times and disasters in response to abnormal brake torque.
- the functions of the operation control means 9, the brake torque check means 10, the disaster control operation means 11, the door open / close determination means 12, the terminal floor travel means 13 and the reporting means 14 are combined into one function.
- it is executed by a computer, it may be executed separately for a plurality of devices.
- the brake torque check method is not particularly limited, and various known methods can be applied.
- the present invention can be applied to an elevator apparatus in which the hoisting machine and the control panel are installed in the machine room at the upper part of the hoistway, and an elevator apparatus of a machine room-less type.
