It is a block diagram which shows the relationship between the elevator apparatus regarding this embodiment, and the building which has a seismic isolation structure part. It is a flowchart of the elevator operation | movement by the control apparatus of the elevator which concerns on this embodiment.

  An elevator control apparatus according to an embodiment of the present invention will be described in detail below with reference to FIGS. In the drawings, 1 is a shake detection signal from a shake detection device, 2 is a shake detection means, 3 is a seismic isolation part position storage means, 4 is a hoisting machine encoder detection signal, 5 is a car position / speed / direction detection means, 6 Is an emergency stop distance storage means, 7 is a seismic isolation structure avoidance operation control means, 10 is an elevator control device, 21 is a hoisting machine, 22 is an encoder, 23 is an elevator control panel, 24 is a car, 25 is a seismic isolation structure section , 26 represents a microcomputer (CPU), respectively.

  In FIG. 1, an elevator control device 10 according to an embodiment of the present invention includes a shake detection means 2 that detects a shake detection signal 1 from an earthquake shake detection device, and a seismic isolation portion position of a building (the seismic isolation portion of FIG. 2). The seismic isolation part position storage means 3 for storing the structure part 25) and the car position / speed / detector for detecting the encoder detection signal 4 from the encoder 22 for outputting the rotation speed, rotation direction and position information of the hoisting machine 21 Direction detection means 5, emergency stop distance storage means 6 for storing the car braking distance at the time of emergency stop, seismic isolation part position storage means 3, car position / speed / direction detection means 5 and emergency stop at the time of shaking detection It is constituted by seismic isolation structure part avoidance operation control means 7 for avoiding the car from stopping at the seismic isolation part based on the information of the distance storage means 6. The seismic isolation structure avoidance operation control means 7 performs operation control that avoids stopping the car in the seismic isolation structure, but as will be understood from the operation flow of FIG. It has a function to control the normal control operation of the elevator.

  The shake detection signal 1 from the shake detection device may be based on a commonly used earthquake detector, but may be provided by means that do not depend on the building's own shake detection device, such as an emergency earthquake warning.

  In FIG. 2, a signal from the encoder 22 generated by the rotation of the hoisting machine 21 is input to the elevator control panel 23, and the traveling of the car 24 is controlled by calculating the car position / speed / direction in the control board 23. is doing. The hatched portion shows an example having the seismic isolation structure 25 having a large shaking in the building. The control panel 23 incorporates a microcomputer (CPU) 26 that functions as a central processing unit.

  An outline of the operation of the elevator control apparatus according to this embodiment will be described below. Fig. 3 shows the flow related to control operation when an earthquake occurs. The basic operation is due to the Elevator Association's seismic control operation.

  When an earthquake occurs, it is determined in steps S301 and 302 whether or not the special low-gull and low-gull detection operations set in advance in the earthquake detector have been performed. When the extra low gull detection is not operating, the operation proceeds to step S4 and the operation is continued. If the extra low gull detection is operating, the process proceeds to step S302.

  When the low-gull detection is operating in step S302, the process proceeds to step S303, and it is determined whether or not the elevator is traveling. If it is not running, the process proceeds to step S5 and the elevator is opened. If the vehicle is traveling, the process proceeds to step S304 to check the operation of the safety circuit. Here, the safety circuit is a circuit for detecting abnormal braking operation, detecting abnormal door opening / closing status, and detecting abnormal car speed operation. If any one of the safety circuits is operating, the process proceeds to step S6, and the elevator is emergency stopped (in the middle of the floor). After an emergency stop, the process proceeds to step S305 to determine whether the safety circuit has returned to normal operation. When not returning, it progresses to step S7 and stops driving | operation.

  If the safety circuit has returned to normal in step S305, or if the safety circuit is not operating in step S304, the process proceeds to step S306 to determine whether the nearest floor is the seismic isolation structure position.

  If it is determined that the nearest floor is not a seismic isolation structure, the process proceeds to step S8, and the elevator is driven to the nearest floor and stopped (the floor that is not the seismic isolation structure is shaken compared to the floor that is the seismic isolation structure). Stop at the floor because it is not large). After stopping to the nearest floor, the door is first opened in step S5, and the passenger is accused. Thereafter, the process proceeds to step S307, and the operation is paused in a state where the determination of step S307 is repeatedly performed so that passengers remaining in the car can escape.

  If it is determined that the nearest floor is the seismic isolation structure, the process proceeds to step S310, and it is determined whether or not the emergency isolation process is stopped when the emergency stop process is performed. This determination is based on the current speed during travel, position, driving direction, and braking distance in the case of emergency stop at each speed, and does not stop before reaching the seismic isolation position (stop before the seismic isolation position). If judged, it will progress to Step S10 and will make an emergency stop of the elevator (in the middle of the floor).

  If it is determined to stop at the seismic isolation position, the process proceeds to step S311 and the operation is continued so as to pass the seismic isolation part. Here, while the operation is continued, the operation state of the safety circuit is repeatedly determined in steps S312 and S313 until the seismic isolation structure portion can be passed. After the seismic isolation part position passage determination, the process proceeds to the previous step S8 to drive the elevator to the nearest floor and stop.

  Here, the operation from step S301 to step 306, step S310 to step S313, step S10 to step S8 will be described repeatedly in relation to the elevator control device shown in FIG. The building has an intermediate seismic isolation structure 25, the position of the structure 25 is stored in the seismic isolation position storage means 3, and the braking distance of the car due to an emergency stop is stored in the emergency stop distance storage 6. The seismic isolation structure avoidance operation control means 7 is detected when the shake detection means 2 detects a shake when the shake detection means 2 shown in FIG. During the control operation to stop the car at the nearest floor, the traveling information of the car by the position / speed / direction detection means 5 of the car and the position information of the seismic isolation structure part 25 from the seismic isolation part position storage means 3 On the basis of the emergency stop distance information from the emergency stop distance storage means 6, operation control is performed so as to prevent the car 24 from stopping at the seismic isolation structure 25.

  The operation control will be specifically described. When it is determined that the nearest floor is the seismic isolation structure 25 at the time of shaking detection (YES in S306 in FIG. 3), the position information and the emergency stop distance information of the seismic isolation structure are included. If it is determined that an emergency stop is possible in front of the seismic isolation structure 25, the car 24 is stopped in the middle of the floor (S10 in FIG. 3), and the nearest floor is the seismic isolation structure 25 when shaking is detected. If it is determined that there is an emergency stop impossible position based on the position information of the base isolation structure and the emergency stop distance information (YES in S310 in FIG. 3), the car 24 passes the base isolation structure. Then, stop processing to the next nearest floor (S8 in FIG. 3) or emergency stop thereafter (it is not shown in FIG. 3, but it is possible to make an emergency stop after passing through the seismic isolation structure). . In this way, when the nearest floor is the seismic isolation structure when the swing is detected and the elevator is traveling, it passes through the seismic isolation structure in consideration of various operating conditions and operation modes or stops at the front. So that the operation is controlled.

  On the other hand, if the low-gull detection is not operating in step S302, the process proceeds to step S320, and it is determined whether the elevator is traveling. If it is not running, the process proceeds to step S13 and the elevator car is opened. If the vehicle is traveling, the process proceeds to step S321 to check the operation of the safety circuit. Here, the safety circuit is the same as described above, and if any one of the safety circuits is operating, the process proceeds to step S11 and the elevator is emergency stopped (in the middle of the floor). After an emergency stop, the process proceeds to step S322 to determine whether the safety circuit has returned to normal operation. When not returning, it progresses to step S7 and stops driving | operation.

  If the safety circuit returns to normal in step S322, or if the safety circuit is not operating in step S321, the process proceeds to step S12, and the door is driven to the nearest floor (step S13). Thereafter, the process proceeds to step S323, and the determination in step S323 is repeated so that passengers remaining in the car can escape. If the operation of the extra low gull detection is performed manually or automatically in step S324, the process proceeds to step S9, and the elevator is normal. It becomes driving.

  As described above, when the earthquake detector detects low-gull in this embodiment, if the elevator is traveling, the current speed during traveling, the current position, the driving direction, and the emergency stop braking distance ( Whether or not to stop at a part (location) of the seismic isolation structure by a predetermined distance (stored in the emergency stop distance storage means 6). Continue driving until you avoid it, and then drive the nearest floor. In addition, since the operation is controlled so as to make an emergency stop if it is determined not to stop, the stop to the seismic isolation structure can be avoided, ensuring the safety of passengers and preventing damage to the car and tower equipment. An effect is obtained.
