If the capture time measurement means to detect and the automatic recall switch at the time of earthquake are ON and the elevator safety device is not operating, the S-wave earthquake detector is reset to temporarily reset the S-wave earthquake detector. The elevator car, when the elapsed time determining means for determining whether or not a predetermined time for waiting for the aftershock or the vibration to settle has elapsed, and when the intake time measuring means and the elapsed time determining means are operated. The vehicle is provided with low-speed descent operation means that descents at a low speed and stops when it reaches the lowest floor, and performs an automatic call-back operation in which an elevator car waits on the lowest floor when an earthquake occurs.

  In addition, when the difference between the operation time of the P wave sensor and the operation time of the S wave seismic detector is 10 seconds or more, the capture time measuring means determines that there is no major property damage accident, being 90 to 100 km away from the epicenter. Is.

  The elevator maintenance management system according to the present invention includes a P wave sensor for detecting an earthquake P wave, an S wave earthquake sensor for detecting an earthquake S wave, a P wave sensor, and an S wave earthquake detector. An elevator control panel that captures the signal of the vehicle, an earthquake control operation means that is provided in the elevator control panel and performs an earthquake control operation that causes the elevator car to stop operation at the nearest floor when the S-wave seismic detector operates, and an elevator Measures the automatic call-back switch at the time of earthquake, the operation time of the P-wave sensor and the operation time of the S-wave seismic detector, and measures that the difference between the operation times exceeds a predetermined value. S-wave seismic detection that resets S-wave seismic detector once if the capture time measuring means to detect and the automatic recall switch at the time of earthquake are ON and the elevator safety device is not operating When the reset means, the elapsed time judgment means that determines whether or not the predetermined time for waiting for the aftershock or the shaking of vibration has elapsed, the take-up time measurement means and the elapsed time judgment means are operated, the elevator car is slowed down.

That is, from past data, for example, when it is about 70-100 km or more away from the epicenter, it is determined that there is no significant damage to the elevator equipment, and the car is automatically operated to the lowest floor and the maintenance engineer's Since it will wait for arrival, the inspection time can be shortened and the labor of the maintenance engineer going up the stairs can be reduced.

Embodiment 1 FIG.
FIG. 1 is a system configuration diagram showing an elevator earthquake response operation apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a flowchart for explaining the operation of the elevator earthquake response operation apparatus according to Embodiment 1 of the present invention. It is.

  In FIG. 1, 1 is a P-wave sensor that detects earthquake P-waves, and 2 is an S-wave earthquake detector that detects earthquake S-waves, which operates at an extra low 60 Gal, low 150 Gal, and high 200 Gal. Only attached to elevators with zones. Reference numeral 3 denotes an elevator control panel that takes in signals from the P-wave sensor 1 and the S-wave earthquake detector 2. An earthquake control operation circuit 4 is provided in the elevator control panel 3. The seismic control operation circuit 4 automatically resets after a predetermined time when the special wave of the S-wave seismic detector 2 operates, and the elevator automatically recovers. If the low or high of the S wave seismic detector 2 operates, the elevator stops operation at the nearest floor, and normally stops until the maintenance engineer arrives and the inspection and restoration work is completed. However, in the present invention, when the earthquake automatic recall switch 5 provided in the elevator control panel 3 is ON, the S-wave earthquake detector 2 is once reset. 6 is a call back circuit provided in the elevator control panel 3, and 7 is an acquisition time measurement circuit provided in the call back circuit 6. The operation time of the P wave sensor 1 and the operation time of the S wave earthquake detector 2 are measured. is doing. When the earthquake occurs, the P-wave sensor 1 is operated, and the S-wave earthquake detector 2 is also operated, the acquisition time measuring circuit 7 measures and detects the difference in operation time. If this time difference is, for example, 10 seconds or more, it is determined that the distance from the epicenter is about 90 km from the speed of the P wave (6 km / sec) and S wave (3.5 km / sec) earthquake motions. Here, the arrival time of the P wave is 90 km / 6 km = 15 seconds, the arrival time of the S wave is 90 km / 3.5 km = 25 seconds, and the S wave arrives 10 seconds after the arrival time of the P wave. Become. Due to recent earthquake conditions, the distance, acceleration, and seismic intensity from the epicenter of the earthquake have been published. And from the correlation between the distance from the epicenter and the acceleration, it was found that when it was 100 km away from the epicenter, it became 50 Gal or less. The correlation between the distance from the epicenter and the seismic intensity showed that the seismic intensity was 4 or less when 50 km away from the epicenter, and the seismic intensity was 3 or less when 100 km away from the epicenter. From this fact, it is known that when it is 90-100 km away from the epicenter, the seismic intensity is 3 or less and the acceleration of the ground surface is about 50 Gal, so that there is no serious property damage accident. Reference numeral 8 denotes an elapsed time determination circuit, which determines, for example, that five minutes have elapsed after waiting for the occurrence of an aftershock and the vibration to settle. Reference numeral 9 denotes an S wave earthquake detector reset circuit. When the earthquake automatic recall switch 5 in the elevator control panel 3 is turned on, the S wave earthquake detector 2 is once reset. Reference numeral 10 denotes a circuit contact for automatic call-back, which is turned on after elapse of 5 minutes, for example, after an aftershock has occurred and the vibration has settled by the elapsed time determination circuit 8. At this time, it is confirmed that the elevator is stopped due to the control operation during the earthquake, and it is confirmed that the safety device is not operating. Then, the S-wave earthquake / earthquake detector 2 is reset once and the automatic call back operation is performed. Reference numeral 11 denotes a door control circuit which is kept closed so that the door does not open. Reference numeral 12 denotes a low-speed descending operation circuit, which operates the elevator to the lowest floor at a low-speed operation and stops the elevator by the end point switch when reaching the lowest floor. In this way, even aftershocks occur, the distance from the epicenter is measured again and the automatic recall operation is performed. If an aftershock occurs again while waiting for the elapsed time or during low-speed operation descent, the time difference between the P wave and S wave is measured again and the call back operation is performed again. And since the elevator car is waiting on the lowest floor, the maintenance engineer who arrives at the building on the site can get on the car immediately without going up the stairs, and can perform inspection and recovery at an early stage. When the car is stopped, the maintenance engineer can easily board the car if the car ceiling is stopped about 60 cm above the floor of the lowest floor + 1 floor.

Next, the operation of the elevator earthquake response operation device will be described with reference to FIG.
When an earthquake occurs, first, in step S1, it is confirmed whether or not the earthquake automatic call back switch 5 provided in the elevator control panel 3 is ON. In step S2, the presence or absence of a P wave signal is confirmed. In S3, the presence or absence of an S wave signal is confirmed. Next, in step S4, whether the time difference between the P wave signal and the S wave signal is 10 seconds or more is measured by the acquisition time measuring circuit 7. This time difference is measured, for example, when the time difference is 10 seconds or more, the distance from the epicenter is determined to be about 90 km from the speed of the P wave (6 km / second) and S wave (3.5 km / second) ground motion. . That is, the arrival time of the P wave is 90 km / 6 km = 15 seconds, the arrival time of the S wave is 90 km / 3.5 km = 25 seconds, and the S wave arrives 10 seconds after the arrival time of the P wave. And according to the recent earthquake situation, the distance, acceleration, and seismic intensity from the epicenter of the earthquake have been announced, and it is known from the correlation between the distance from the epicenter and the acceleration that it becomes 50 Gal or less when 100 km away from the epicenter. . The correlation between the distance from the epicenter and the seismic intensity indicates that the seismic intensity is 4 or less when 50 km away from the epicenter, and the seismic intensity is 3 or less when 100 km away from the epicenter. From these facts, it is known that when it is 90 to 100 km away from the epicenter, the seismic intensity is 3 or less and the acceleration of the ground surface is about 50 Gal, and there is no major property damage accident. Therefore, it is important to measure whether the time difference between the P wave signal and the S wave signal is 10 seconds or more, for example. In step S5, it is confirmed whether the elevator car is on the lowest floor. If the elevator safety device is not operating (step S6), the S-wave earthquake detector 2 is once reset by the S-wave earthquake detector reset circuit 9 (step S7). Next, in step S8, the elapsed time determination circuit 8 determines whether, for example, 5 minutes have elapsed since the S wave signal was sensed. And if there is no S wave signal at step S9, it will progress to step S10 and will perform a descent | fall operation to the lowest floor at a low speed. When it reaches the lowest floor (step S11), it is stopped by the end point switch, and the elevator stops its operation (step S12). When an aftershock occurs in step S9 and an S wave signal is detected, the process returns to step S2 and again measures the distance from the epicenter. If an aftershock occurs again during the low-speed operation descent in step S11, the time difference between the P wave and the S wave is measured again and the recall operation is performed again. Thereby, since the elevator car is waiting on the lowest floor, a maintenance engineer who arrives at the building on the site can get on the car immediately without going up the stairs, and can perform inspection and recovery at an early stage. When the car is stopped, the maintenance engineer can easily board the car if the car ceiling is stopped about 60 cm above the floor of the lowest floor + 1 floor.
