Abstract

If a long-period earthquake occurs, it is judged whether any failure is caused or not, and an elevator can be recovered, if any, to its normal operation safely and quickly. An elevator control apparatus comprises a general earthquake sensor and a long-period earthquake sensor which senses the long-period component of the vibration of a building in two levels which the general earthquake sensor does not senses. When the earthquake sensor senses a vibration, an earthquake time control operation is carried out. If the long-period earthquake sensor senses a first level, a long-period earthquake time control operation including report to the outside and inside of the elevator is carried out. If the long-period earthquake sensor senses a second level, a long-period earthquake time control operation is carried out in which a report is sent to the outside and inside of the elevator, the car is moved to the nearest floors and stopped, the door is opened and the closed, the car is moved to a resting floor, and the operation is stopped. Under a predetermined condition, an automatic inspection operation is carried out. If no failure is found out, the operation is returned to the normal operation.

Description

Elevator control device and control method {ELEVATOR CONTROL APPARATUS AND CONTROL METHOD}

The present invention relates to a control device and a control method of an elevator that performs a control operation in response to the shaking of a building when a shaking occurs in the building due to an earthquake or the like.

In areas where earthquakes occur frequently, such as Japan, elevators equipped with the function of controlling the earthquake according to the shaking of the building during the earthquake, that is, the operation state of the earthquake detector, are spreading. Further, the seismic detector is composed of a two-dimensional accelerometer or the like installed in the machine room of an elevator, and when a shake of a predetermined value or more is detected by such an earthquake detector, for example, the car is stopped on the nearest floor. Thereafter, the same control as for performing the door opening operation is performed.

As a prior art of an elevator having such an earthquake control operation, for example, a first earthquake detector for detecting a predetermined high level shake, and a second earthquake detector for detecting a predetermined low level shake, In the case where each earthquake detector has been operated, it is proposed to perform an earthquake control operation according to the level of shaking. In such an elevator, the car is emergency stopped when the first earthquake detector is operated. In addition, when the second earthquake detector operates, first of all, the safety circuit is automatically checked after a predetermined time elapses when the car is stopped at the nearest floor and the end of the earthquake is expected. And when abnormality is not found by the inspection of a safety circuit, it returns to normal operation under predetermined conditions (refer patent document 1).

In addition, as a conventional technology of an elevator that performs control operation in accordance with the shaking of a building, a wave energy detector capable of detecting a plurality of strong wind levels and a control device for controlling the elevator based on an output signal from the wave energy detector are provided. In addition, it is proposed to carry out rational control operation according to the shaking of an actual building at high winds. In such an elevator, a strong wind signal indicating that a strong wind is detected from the wave energy detector and a plurality of signals indicating the level of the strong wind are output from the wave energy detector. And the control apparatus which received each signal performs control operation, such as a deceleration operation, an intermediate | middle layer standby, and stop, according to strong wind level based on each received signal (for example, refer patent document 2).

In recent years, when a relatively large earthquake occurs in a remote place due to the high rise of a building equipped with an elevator, the control of the elevator even when the shaking such as the control operation during the earthquake is not detected by the earthquake detector. Long cables such as cables and balance ropes are shaken, and there have been reports of collisions or jamming of devices in the hoistway. This occurs because the building vibrates at a long cycle due to an earthquake generated at a remote location. If the car continues to run in such a state, damage to the control cable or the like or damage to the equipment in the hoistway may occur.

For this reason, the development of a new type of earthquake detector, which is different from the conventional earthquake detector, that is, a long period earthquake detector capable of detecting the long period component of the shaking of buildings.

In addition, based on information from seismographs (earthquake detectors) installed throughout Japan, emergency earthquake breaking news is sent to various places immediately after an earthquake by using the Internet or satellite communication, which is effective for earthquakes before reaching the main movement of the earthquake. Approach and suggestion to take measures are also carried out. Here, the emergency earthquake breaking news is composed of various information such as the time of the earthquake, the magnitude of the earthquake, the epicenter, the amount of time until the main movement of the earthquake is reached, and the like. In addition, in the transmission of the emergency earthquake breaking news, with the recent increase in the speed and capacity of general public lines, a high-speed digital line network for realizing the Internet and the like has been widely maintained, which makes it possible to transmit information in real time at high speed. Based on technical background. In addition, since the emergency earthquake breaking news is transmitted after an earthquake is generated, it cannot be effectively used when a direct type earthquake occurs. However, when a relatively large earthquake occurs at a remote location, it may take some time before the main movement is reached after receiving the emergency earthquake breaking news. Therefore, if the emergency earthquake breaking news is effectively used, it is possible to prevent earthquake damage in advance. It becomes possible.

As a conventional technique of an elevator using such an emergency earthquake breaking news, by receiving an emergency earthquake breaking news including the epicenter and earthquake occurrence time of an earthquake, the time of arrival of the seismic wave is predicted from the received emergency earthquake breaking news at the present location, It is proposed to control the control operation at the time of an elevator earthquake based on (for example, refer patent document 3).

The long-term earthquake component of the shaking of the building is detected by the long-term earthquake detector 3 by the long-term earthquake detector 3, and the operation mode recovery means 1e is not abnormal in various equipments of the elevator after the operation mode is shifted from the normal operation to the long-term earthquake control operation. Means for automatically returning to normal operation under predetermined conditions. Specifically, the driving mode recovery means 1e is a case in which the long period component of the second level is not detected within a predetermined time after the long period component of the first level is detected by the long period earthquake detector 3. When a predetermined time has elapsed since the long period component of the level is not detected, the shaking of the building is considered to be calm and automatically returns to normal operation. In addition, the operation mode recovery means 1e is a case where the long period component of the second level is detected within a predetermined time after the long period component of the first level is detected by the long period earthquake detector 3, If no abnormality is found by the automatic check operation, it is assumed that there is no damage caused by a long period earthquake, and automatically returns to normal operation.

Next, operation | movement of the control apparatus of the elevator which has the said structure is demonstrated based on FIG.

In the normal operation of an elevator, the control apparatus 1 always determines whether the earthquake generate | occur | produces (shaking of a building). Specifically, the control device 1 determines whether the normal earthquake detector 2 is operating, that is, whether or not earthquake detection information has been input from the earthquake detector 2 to the information input / output means 1a ( Step S101). In addition, when an earthquake occurs in the vicinity of a building equipped with an elevator, the shaking of the building due to the earthquake is detected by the ordinary earthquake detector 2, and the earthquake detection information corresponding to the detected level of shaking is detected by the earthquake detector ( 2) is input to the information input / output means 1a. In the control apparatus 1, when earthquake detection information is input to the information input / output means 1a, a driving mode is shifted from normal operation to normal earthquake control operation (step S102), and the operation control means 1b Control the operation of the earthquake according to the level of shaking of the building. Then, after the earthquake control operation is completed, the inspection is performed by the maintenance worker of the elevator. In this case, the elevator returns to the normal operation (step S104) by checking the normal state and manually resetting by the maintenance worker (step S103).

In addition, in the control apparatus 1, the presence or absence of the long-term earthquake occurrence is always determined in addition to the normal earthquake occurrence. Specifically, when the earthquake detector 2 is not operating (step S101), it is determined by the control device 1 whether the long period earthquake detector 3 has sensed the long period component of the first level (step S101). S105). In addition, when the long period component of the first level is not detected by the long period earthquake detector 3, the control device 1 continuously determines whether normal earthquake and long period earthquake are generated (steps S101 and S105). .

On the other hand, when the long period component of the first level is detected by the long period earthquake detector 3 (step S105), the long period earthquake detection information of the first level is input from the long period earthquake detector 3 to the information input / output means 1a. In the control device 1, the long period earthquake detection information of the first level is input to the information input / output means 1a, thereby shifting the operation mode from the normal operation to the long period earthquake control operation, and the long period earthquake first level control operation means. In (1c), the long-term earthquake control operation is performed at the first level. Specifically, the long-term earthquake first-level control operation means 1c uses the long-term earthquake first-level control driving means 1c to give the monitoring panel 4 a first level or the like 4a in order to give a notice for alerting the outside of the elevator and the inside of the car 5. A lighting command for turning on the light is output so that the first level lamp 4a lights up, and the voice guidance from the announce device 5a and the display guidance of the display device 5b are performed (step S106).

In addition, after the long period component of the first level is detected by the long period earthquake detector 3, the control device 1 determines whether the long period component of the second level is detected by the long period earthquake detector 3 within a predetermined time. It is determined (step S107). If the long period component of the second level is not detected by the long period earthquake detector 3 within the predetermined time (step S107), if a predetermined time has elapsed since the long period component of the first level is not detected, It is determined that the shaking is calm, and is automatically reset by the operation mode recovery means 1e (step S108), and the operation returns to normal operation (step S104).

On the other hand, when the long period component of the second level is detected by the long period earthquake detector 3 (step S107), the long period earthquake detection information of the second level is input from the long period earthquake detector 3 to the information input / output means 1a. In the control apparatus 1, the long period earthquake detection information of a 2nd level is input into the information input / output means 1a, and the long period earthquake 2nd level control operation means 1d controls the 2nd level long period earthquake control operation. Is carried out. Specifically, the second level light 4b is turned on for the monitoring panel 4 by the long-term earthquake second level control operation means 1d to give a notification to warn the outside of the elevator and the inside of the car 5. A lighting command for outputting is output so that the second level lamp 4b lights up, and the voice guidance from the announce device 5a and the display guidance of the display device 5b are performed (step S109).

In the long-term earthquake control operation of the second level, the car 5 is driven to the nearest floor, and the door is opened after stopping at the nearest floor to rescue the passengers in the car 5. In addition, in order to prevent a person getting into the cage | basket | car 5 wrongly, the door close operation | movement is performed after the predetermined time elapses after starting a door opening operation | movement, and all doors remain closed after that (step S110). After the doors are all closed, the car 5 is driven at a low speed to a predetermined rest floor (step S111), and the stop layer is stopped, and the driving stop state is maintained as it is (step S112). Here, even if the cage | basket | car 5 stops, the said resting layer is set to the floor floor etc. in which the elongate member of an elevator, such as a main rope, did not resonate with the shaking of a building.

Further, after the operation stop state, the long period earthquake detector 3 determines whether or not the long period components of the first level and the second level have been detected for a predetermined time (step S113). If the long period component of the first level or the second level is detected by the long period earthquake detector 3 within the predetermined time (step S113), the operation stop state is continued again (step S112).

On the other hand, when the long period earthquake detector 3 does not detect the long period components of the first level and the second level for a predetermined time (step S113), the car 5 is driven at a low speed to cause abnormalities in the equipment and mains. Carry out an automatic check operation to detect jams such as ropes. In addition, in the said automatic inspection operation, abnormality of an elevator is carried out by monitoring the torque of a hoisting machine (not shown), etc., for example, making the cage | basket | car 5 reciprocate in a hoistway at low speed. Is automatically detected. Specifically, the car 5 is driven from the rest floor to the top floor at low speed (step S114), and it is determined whether the operation of various safety switches has been detected while traveling (step S115). Further, after driving the car 5 to the uppermost floor, the car 5 is further driven to the lowest floor at low speed (step S116), and it is determined whether the operation of various safety switches has been detected while traveling (step S117). ). Here, when the operation of the safety switch is detected during the automatic inspection operation in steps S114 and S116, it is assumed that an abnormality in the elevator is found, and the car 5 is emergency stopped (step S118).

In addition, the long-term earthquake control operation of the second level including the automatic inspection operation is controlled by the long-term earthquake second-level control operation means 1d.

And when the cage | basket | car 5 is urgently stopped in the said automatic inspection operation (step S118), it automatically resets after a steady state is confirmed by the inspection which an elevator maintenance worker performs (step S119), and returns to normal operation. (Step S104). If no abnormality is found by the automatic check operation, it is automatically reset by the operation mode recovery means 1e (step S108) and returns to normal operation (step S104).

In addition, although not shown in Fig. 2, even after the long period component of the first level is detected by the long period earthquake detector 3 in step S105, when the shaking of the building is detected by the earthquake detector 2, the operation mode is From the long period earthquake control operation to the normal earthquake control operation, the operation control means 1b preferentially performs the earthquake control operation in accordance with the level of shaking of the building.

According to the first embodiment of the present invention, even when a predetermined long period component of the shaking of the building is detected by the long period earthquake detector 3, the abnormality of the elevator can be reliably determined, and it is possible to safely return to normal operation. . Moreover, when abnormality of an elevator is not found, it is possible to return to normal operation early, and the effect which shortens the stopping time of an elevator can be expected.

Embodiment 2.

FIG. 3 is a block diagram showing an elevator control device according to the second embodiment of the present invention. FIG. 4 is a flowchart showing the operation of the elevator control device according to the second embodiment of the present invention. First, the structure of the elevator control apparatus is demonstrated based on FIG. 6 is an emergency earthquake breaking news receiver which is provided in the building with an elevator and receives the emergency earthquake breaking news of the earthquake which generate | occur | produced in the case of an earthquake. In addition, the emergency earthquake breaking news is composed of various information such as the time of the earthquake, the magnitude of the earthquake, the epicenter, the free time until the main movement of the earthquake, and the like. It is transmitted using a high speed communication network such as the Internet or satellite communication. In addition, a high-speed communication network for delivering emergency earthquake breaking news, for example, is based on a highly secure Virtual Private Network (VPN) or an Asymmetric Digital Subscriber Line (ADSL) for general home use, which is frequently used on the Internet between companies. It is transmitted using a high-speed digital line network or a line network such as broadcast via satellite.

Further, the emergency earthquake breaking news receiving device 6 is connected to the control device 1 by a communication line or the like, and when the emergency earthquake breaking news is received, emergency earthquake information is transmitted to the control device 1 under a predetermined condition. Output That is, when the emergency earthquake breaking news receiver 6 receives the emergency earthquake breaking news, the earthquake motion exceeding a certain threshold is reached by calculating the degree of influence on the building equipped with the elevator based on the received emergency earthquake breaking news. If it is determined that emergency earthquake information is output to the control apparatus 1, it is output.

In addition, emergency earthquake information is output from the emergency earthquake breaking news reception device 6 to the control device 1 in the long period earthquake first level control driving means 1c and the long period earthquake second level control driving means 1d. In the case where a predetermined long period component of the shaking of the building is detected by the long period earthquake detector 3, it is configured to perform a control operation during a long period earthquake. In addition, the other structure is the same as that of Embodiment 1.

Next, operation | movement of the control apparatus of the elevator which has the said structure is demonstrated based on FIG.

In FIG. 4, step S201 is performed when the normal earthquake detector 2 is not operating in step S101 in FIG. 2. That is, when the control apparatus 1 determines that the normal earthquake detector 2 is not operating, it is determined next whether emergency earthquake information is input from the emergency earthquake breaking news reception device 6 (step S201). ). Here, when emergency earthquake information is not input from the emergency earthquake breaking news receiving device 6, the control apparatus 1 continues and determines whether the normal earthquake and the long period earthquake generate | occur | produce.

On the other hand, when emergency earthquake information is input from the emergency earthquake breaking news receiving device 6 (step S201), it is determined by the long period earthquake detector 3 whether a predetermined long period component of the shaking of the building has been detected (step S201). S202). When the predetermined long period component of the shaking of the building is not detected by the long period earthquake detector 3, an error of the emergency earthquake breaking news or an earthquake actually occurred in a distant place does not affect the building. Termination, that is, whether normal earthquakes and long period earthquakes occur again is determined.

In addition, when the predetermined long period component of the shaking of the building is detected by the long period earthquake detector 3 (step S202), the long period earthquake control operation described in step S106 or lower in FIG. 2 is performed (step S203). In addition, even when a predetermined long period component of the shaking of the building is detected by the long period earthquake detector 3, when emergency earthquake information is not input to the control device 1, the long period earthquake control operation is not performed.

According to the second embodiment of the present invention, the building is actually combined with the reception of the emergency earthquake breaking news by the emergency earthquake breaking news reception device 6 and the detection of the long period component of the shaking of the building by the long period earthquake detector 3. Since it is judged whether or not it vibrates at a long period, it is possible to realize a high-precision long-term earthquake control operation as a system. In other words, even when an error detection of the long period earthquake detector 3 or an error of the emergency earthquake breaking news occurs, when the building is actually vibrating at a long period due to an earthquake generated at a remote location without deteriorating the operating efficiency of the elevator, it is assured. In the long cycle earthquake can be controlled.

Moreover, you may be comprised so that emergency earthquake information of several levels may be output from the said earthquake breaking news receiver 6, and the control apparatus 1 may perform control corresponding to emergency earthquake information of each level.
