In Fig. 1 , an elevator control device 10 according to an embodiment of the present invention has: a shaking detection unit 2 that detects a shaking detection signal 1 output by a shaking detection device of an earthquake; Detect the elevator car position, speed and direction detection unit 5 of the encoder detection signal 4 from the encoder 22, wherein the encoder 22 output and hoisting machine 21 Information related to the number of rotations, direction of rotation, and position; the emergency stop distance storage unit 6 for storing the braking distance of the elevator car during an emergency stop; The speed and direction detection unit 5 and the information of the emergency stop distance storage unit 6 prevent the elevator car from stopping at the shock absorbing structure part of the shock absorbing part and avoid the operation control unit 7. Wherein, the shock-absorbing structure avoids the operation control unit 7, except that the operation control is performed to prevent the elevator car from stopping at the shock-absorbing structure. It can also be known from the operation flow chart of Fig. 3 described later that the shock-absorbing structure Of course, the avoidance operation control unit 7 also has the function of controlling the normal regulation operation of the elevator.

The shaking detection signal 1 from the shaking detection device may be a signal output from a widely used earthquake sensor, and may also be information detected by a device other than the shaking detection device of the building itself, for example, it may be an emergency earthquake report, etc. information provided.

In Fig. 2, as the winch 21 rotates, the signal of the encoder 22 is input into the elevator control panel 23, and the travel of the elevator car 24 is controlled by calculating the position, speed and direction of the elevator car in the control panel 23 . The hatched part exemplifies the shock-absorbing structure part 25 in the building where the sloshing is relatively large. A microcomputer (CPU) 26 functioning as a central processing unit is incorporated in the control panel 23 .

The outline of the operation of the elevator control device according to this embodiment will be described below. Fig. 3 shows the flow of the control operation when an earthquake occurs. The basic operation is formulated in accordance with the earthquake control operation method of the Elevator Association.

When an earthquake has taken place, it is judged in step S301 and step S302 whether the ultra-low gal (extra-low gal) or the low-gal sensor set in the seismic sensor in advance have acted. When the ultra-low gamma sensor is not in action, proceed to step S4 to continue running. When the ultra-low gamma sensor operates, go to step S302.

When the low gamma sensor is activated in step S302, proceed to step S303 to determine whether the elevator is running. Under the situation that elevator is not running, enter step S5, make elevator door open. When the elevator is running, proceed to step S304 to confirm the operation of the safety circuit. Among them, the safety circuit is a circuit for detecting abnormal action of the brake, abnormal opening and closing of the elevator door, and abnormal action of the speed of the elevator car. When any one of the safety circuits in the safety circuit is in operation, proceed to step S6 to make the elevator emergency stop (in the middle of the floor). After the emergency stop, go to step S305 to judge whether the safety circuit has returned to normal operation. If the normal operation has not been restored, proceed to step S7 to stop the operation.

In step S305, if the safety circuit returns to normal operation, or the safety circuit does not operate in step S304, then enter step S306, and determine whether the nearest floor is a shock-absorbing structure position.

Under the situation of judging that the nearest floor is not a shock-absorbing structure portion, enter step S8, make the elevator run to the nearest floor and make it stop (compared with the floors as the shock-absorbing structure portion, the shaking of the floors that do not belong to the shock-absorbing structure portion smaller, so dock on this floor). After stopping at the nearest floor, in step S5, at first the action of making the elevator door open is performed so that the passengers can take refuge. Enter step S307 after this, in order to allow the passenger staying in the elevator car to escape from the elevator, repeatedly carry out the judging action of step S307, stop running after this.

When it is judged that the nearest floor is the shock absorbing structure part, it proceeds to step S310, and it is judged whether the elevator car will stop at the shock absorbing structure position when the emergency stop process is performed. Wherein, this judgment is carried out according to the current speed, position, running direction of the elevator in travel and the braking distance when performing an emergency stop at various speeds. Stop near the damping position), then enter step S10, make the elevator emergency stop (on the way on the floor).

When it is judged that the elevator car will stop at the shock absorbing position, enter step S311 to make the elevator continue to run and pass the shock absorbing position. Wherein, during the continuation of running, the operation state of the safety circuit is repeatedly judged in steps S312 and S313 until the position where the vehicle can travel past the shock absorbing structure. After judging that the position of the shock absorbing part has been passed, it enters the previous step S8, and makes the elevator stop at the nearest floor after running to the nearest floor.

Hereinafter, the correlation between the operation from step S301 through step S306, step S310 to step S313, and step S10 to step S8 and the elevator control device shown in FIG. 1 will be described again. The building has an intermediate damping structure part 25, the position of the structure part 25 is stored in the shock absorbing part position storage unit 3 in advance, and the braking distance when the elevator car is stopped in an emergency is stored in the emergency stop distance storage unit 6, When the shaking detection unit 2 shown in FIG. 1 detects that the ultra-low gamma sensor and the low gamma sensor have acted, the shock-absorbing structure part avoids the operation control unit 7 when the shaking detection unit 2 detects the shaking and makes the elevator car When the car stops to the control operation of the nearest floor, according to the running information of the elevator car detected by the position, speed and direction detection unit 5 of the elevator car, the position of the shock absorbing structure part 25 from the shock absorbing part position storage unit 3 information and the emergency stop distance information from the emergency stop distance storage unit 6 for operation control, so as to prevent the elevator car 24 from stopping at the shock absorbing structure part 25 .

Hereinafter, this operation control will be described in detail. When shaking is detected, if it is determined that the nearest floor is the shock absorbing structure 25 (S306 in FIG. 3 is Yes), the position information of the shock absorbing structure and the emergency stop distance Information is judged, when judging that it is the position that can make an emergency stop in front of the shock-absorbing structure part 25, the elevator car 24 is made to make an emergency stop in the middle of the floor (S10 of Fig. 3), when shaking is detected, when it is judged that it is the nearest floor In the case of the shock-absorbing structure part 25 (S310 of FIG. 3 is YES), if it is judged to be in a position where an emergency stop cannot be made according to the position information of the shock-absorbing structure part and the emergency stop distance information, the elevator car 24 is passed by. The shock absorbing structure part carries out stop processing (S8 of Fig. 3) to the next nearest floor, or an emergency stop after passing the shock absorbing structure part (although it is not shown in Fig. emergency stop after the structure department). As mentioned above, the so-called operation control means that after the shaking is detected, if the elevator is running and the nearest floor is a shock-absorbing structure, the operation control is carried out according to various operating conditions and operating states, so that the elevator passes The shock absorbing structure part or stops in front of the shock absorbing structure part.

On the other hand, if the low gamma sensor does not operate in step S302, then enter step S320 to judge whether the elevator is running. When the elevator is not running, the process proceeds to step S13 to open the door of the elevator car. When the elevator is running, the process proceeds to step S321 to confirm the operation of the safety circuit. Here, the safety circuit is the same as the above-mentioned safety circuit, and when any one of the safety circuits in the safety circuit operates, the process proceeds to step S11 to make an emergency stop of the elevator (in the middle of the floor). After the emergency stop, proceed to step S322 to determine whether the safety circuit has returned to normal operation. Under the situation that does not return to normal action, enter step S7, make elevator stop running.

When judging in step S322 that the safety circuit has returned to the normal action, or judging in step S321 that the safety circuit has not acted, enter step S12, make the elevator run to the nearest floor and open the elevator door (step S13 ). After this, enter step S323, repeatedly carry out the judgment of step S323, so that the passenger who stays in the elevator car can escape from the elevator, if in step S324, the action of ultra-low gamma sensor is manually or automatically reset, then enter step S9 , to make the elevator run normally.

As mentioned above, in this embodiment, when the earthquake sensor detects that the low-gamma sensor is in motion, if the elevator is running, the emergency stop at the speed will be performed based on the current speed, current position, and running direction of the running elevator. Braking distance (a distance obtained in advance and stored in the emergency stop distance storage unit 6), it is judged whether the elevator car will stop at the position (place) of the shock absorbing structure part, and when it is judged that it will stop at the shock absorbing structure part When the location (location) of the elevator is not reached, the elevator continues to run until it reaches a position where the shock-absorbing structure can be avoided, and then runs to the nearest floor. In addition, when it is judged that it will not stop at the position (place) of the shock-absorbing structure, the operation of the elevator is controlled to make the elevator stop urgently, so that the elevator car can be prevented from stopping at the shock-absorbing structure, thereby ensuring the safety of passengers. In addition, it is possible to obtain the effect of preventing the elevator car and the equipment in the passage from being damaged.
