Description

  The present invention relates to a technique for stopping an elevator operation based on earthquake arrival prediction information for predicting the arrival of an earthquake and restarting the operation in a predetermined case.

As a technique related to the present invention, there is a technique described in Patent Document 1.
In the technique of Patent Document 1, the flow shown in FIG. 5 is performed.
Below, the technique of patent document 1 is demonstrated easily according to the flow of FIG.

The control device main body that controls the operation of the elevator car monitors whether or not earthquake arrival prediction information is received (step ST201). The earthquake arrival prediction information is information for notifying the estimated seismic intensity of an earthquake before the earthquake reaches a building or the like where an elevator car is installed.
Then, when receiving the earthquake arrival prediction information, the control device main body acquires the estimated seismic intensity included in the earthquake arrival prediction information, and confirms whether the estimated seismic intensity is equal to or higher than the reference seismic intensity (step ST202).
If the estimated seismic intensity is equal to or greater than the reference seismic intensity, the controller main unit records the earthquake arrival prediction information (step ST203), switches the operation mode to the operation mode during earthquake, stops the elevator car at the nearest floor, and opens the door once. Then, the door is closed and the elevator is put into operation stop (step ST204).
Then, when the operation is suspended, the control device main body monitors whether or not the earthquake sensing device provided in the building where the elevator car is installed senses the shaking of the earthquake (step ST205). On the other hand, if the estimated seismic intensity is less than the reference seismic intensity, the control device main body monitors whether the seismic sensing device senses an earthquake shake while maintaining the normal operation mode (step ST205).
When the earthquake sensing device senses an earthquake shake, the control device main body records the operation of the earthquake sensing device (step ST206), shifts to the operation mode during earthquake, and puts the elevator into operation suspension (step ST207). .
Then, the control device main body returns to normal operation (step ST211) when it receives inspection and manual reset (step ST208) of the hoistway and the car by the maintenance staff.
Further, when the earthquake sensing device has not sensed the shaking of the earthquake, the control device body confirms whether or not the earthquake arrival prediction information has been recorded (step ST209). When the earthquake arrival prediction information is recorded, the control device main body performs automatic reset after the standby time has elapsed (step ST210). When the earthquake arrival prediction information is not recorded, the control device body 1 monitors whether the earthquake arrival prediction information is received as it is.

JP 2007-45562 A

In the technique of Patent Document 1, when returning to normal operation after automatic reset, the elevator suddenly cancels the dormant state. Therefore, the elevator user returns to normal operation for what reason the elevator user returns to normal operation. There is a problem that elevator users become uneasy because it is not known whether the cancellation of the state is due to normal operation or due to failure or trouble.
In addition, if the earthquake detection device is out of order, it automatically resets after the standby time has elapsed and returns to normal operation, so there is a risk of returning to normal operation even if the elevator is damaged by an earthquake. There is a problem that there is.

  One of the main objects of the present invention is to solve the above-mentioned problems, and when the operation is resumed after the operation of the elevator is suspended based on the earthquake arrival prediction information, the user of the elevator is anxious. The main purpose is to realize a mechanism that does not resume the operation of the elevator when an earthquake occurs.

  The control device body 1 includes an earthquake information input unit 1a, an earthquake operation selection unit 1b, an earthquake operation recovery unit 1c, an earthquake information recording unit 1d, a travel availability determination unit 1e, and a message output unit 1f.

The earthquake information input unit 1a receives earthquake detection information and earthquake arrival prediction information from the outside.
The seismic operation selection unit 1b stops the operation of the elevator when the estimated seismic intensity notified in the earthquake arrival prediction information is greater than or equal to a predetermined reference seismic intensity.
When the earthquake detection device 3 does not detect an earthquake even after a predetermined time has elapsed since the input of the earthquake arrival prediction information by the earthquake information input unit 1a, the operation recovery unit 1c during the earthquake suspends the operation by the operation selection unit 1b during the earthquake. Restart the running elevator.
The earthquake information recording unit 1d stores the input earthquake detection information.
The travel propriety determination unit 1e performs operation stop determination and confirmation of a stop location in the operation mode during an earthquake.
The message output unit 1f outputs a message to the effect that the operation of the elevator is resumed in the elevator prior to the operation of the elevator being resumed by the earthquake operation recovery unit 1c.

The control device main body 1 is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a storage device such as a magnetic disk device 920, a communication board 915, and the like. Can be realized.

Alternatively, it may be implemented only by software, or only by hardware such as elements, devices, substrates, and wirings, by a combination of software and hardware, or by a combination of firmware.
Each element of the control device main body 1 can also be expressed as “˜step”, “˜procedure”, and “˜processing”.

Next, an operation example of the control device main body 1 according to the present embodiment will be described with reference to the flowchart of FIG.
In FIG. 2, ST201 to ST211 are the same as ST201 to ST211 shown in FIG.
In the present embodiment, the processes of ST101 and ST102 are added.
Hereinafter, each step of FIG. 2 including ST201 to ST211 will be described.

First, when the earthquake information input unit 1a receives the earthquake arrival prediction information (YES in step ST201), the earthquake operation selection unit 1b acquires the estimated seismic intensity included in the earthquake arrival prediction information, and the estimated seismic intensity is the standard. It is confirmed whether or not the seismic intensity is greater than or equal to (step ST202).
When the estimated seismic intensity is equal to or greater than the reference seismic intensity, the earthquake operation selection unit 1b records the earthquake arrival prediction information in the earthquake information recording unit 1d (step ST203), switches the operation mode to the operation mode during earthquake, and sets the elevator car to the highest level. The vehicle is stopped at the floor, and once opened, the door is closed, and the elevator is stopped (step ST204).
Then, when the operation is suspended, the operation selection unit 1b at the time of the earthquake monitors whether or not the earthquake detection device 3 detects the shaking of the earthquake (step ST205). On the other hand, when the estimated seismic intensity is less than the reference seismic intensity, the seismic operation selection unit 1b monitors whether or not the seismic sensing device 3 senses an earthquake shake while maintaining the normal operation mode (step ST205).
When the earthquake detection device 3 detects an earthquake shake, the earthquake information recording unit 1d records the operation of the earthquake detection device 3 (step ST206), shifts to the operation mode during earthquake, and stops the elevator operation. (Step ST207).
And the control apparatus main body 1 will return to normal driving | operation (step ST211), if a hoistway and a cage | basket | car inspection and manual reset (step ST208) are received by a maintenance worker.

On the other hand, in ST205, when the earthquake detection device 3 does not detect the shaking of the earthquake, the operation selector 1b at the time of the earthquake confirms whether or not the earthquake arrival prediction information has been recorded (step ST209). And when there is a record of earthquake arrival prediction information, when the earthquake detection device 3 does not detect the shaking of the earthquake even after a predetermined time has elapsed (YES in step ST101), the operation restoration unit 1c at the time of the earthquake is the elevator. The operation mode is shifted to the temporary recovery mode so that the elevator car can output a voice message, the message output unit 1f transmits the voice message to the elevator car, and the voice message is output in the elevator car (step ST102). .
In the temporary recovery mode, the message output unit 1f may, for example, say “Earthquake early warning was received but no earthquake was detected after a predetermined time, so the elevator was returned to normal operation. Send "Mass" to the elevator.
When a certain time (for example, 20 minutes) elapses after the transition to the temporary restoration mode, the earthquake operation restoration unit 1c performs automatic reset, and the elevator returns to normal operation (step ST211).

  With the above configuration, the elevator users (including elevator managers and maintenance personnel) understand the situation by voice message and explain why the elevators that have been out of service are restored. Can be increased.

  As described above, in the present embodiment, when the earthquake arrival prediction information is received, the estimated seismic intensity is equal to or higher than the reference seismic intensity, and the earthquake detection device does not operate, after the standby time has elapsed, the temporary recovery mode is entered and the elevator user is informed. An elevator control device has been described in which the situation is notified and the elevator user can understand the situation by returning to normal operation after the standby time has elapsed, thereby enhancing the sense of security.

Embodiment 2. FIG.
FIG. 3 is a block diagram showing an elevator control apparatus according to the present embodiment.
3 is different from FIG. 1 in that a button operation detection unit 1g is added.

  The button operation detection unit 1g accepts a button operation in the elevator when the earthquake detection device 3 does not detect an earthquake even after a predetermined time has elapsed from the input of the earthquake arrival prediction information by the earthquake information input unit 1a. It is determined whether or not a button operation for requesting resumption of operation of the elevator has been performed. When a button operation for requesting resumption of operation of the elevator is performed in the elevator, the resumption of operation of the elevator is performed to the operation restoration unit 1c during an earthquake. Instruct.

Next, an example of the operation of the control device main body 1 according to the present embodiment will be described with reference to the flowchart of FIG.
In the following, description will be given with an emphasis on differences from FIG. 2 described in the first embodiment.

In ST205, when the earthquake detection device 3 does not detect the shaking of the earthquake, the operation selection unit 1b during earthquake confirms whether or not the earthquake arrival prediction information is recorded (step 209), and the earthquake arrival prediction information is recorded. In some cases, when the earthquake detection device 3 does not detect the shaking of the earthquake even after a predetermined time has elapsed (YES in step ST101), the operation recovery unit 1c during the earthquake shifts the operation mode of the elevator to the temporary recovery mode. The elevator car is ready to output a voice message, the message output unit 1f transmits the voice message to the elevator car, and the voice message is output to the elevator car (step ST103).
The voice message in the car in this embodiment is, for example, “Earthquake early warning was received, but no earthquake was detected after a predetermined time, so the elevator returns to normal operation. After confirming that there is no shaking, press the password button for the administrator. Do not perform this operation if there is a large shaking. " This message prompts button operation when there is no message.

After the transition to the temporary recovery mode, when the specific button A (for example, the “close” button, the “open” button, and the “1” button are pressed simultaneously) is pressed (step ST104), the button operation detection unit 1g The button operation is accepted, it is determined that there has been an earthquake shake, the earthquake operation recovery unit 1c is instructed to shift to the earthquake operation mode, the earthquake operation recovery unit 1c shifts to the earthquake operation mode, and the elevator Is stopped (step ST105).
If there is a manual reset by maintenance personnel after the shift to the earthquake operation mode (step ST107), the mode shifts to the normal operation mode (step ST108).

  When the specific button B (for example, the “close” button, the “open” button, and the “2” button are simultaneously pressed) is pressed after the transition to the temporary recovery mode (step ST106), the button operation detecting unit 1g The button operation is accepted, it is determined that there is no earthquake shaking, the earthquake operation recovery unit 1c is instructed to shift to the normal operation mode, the earthquake operation recovery unit 1c shifts to the normal operation mode, and the elevator is Returning to operation (step ST108).

Since it was configured as described above, after the elevator users (mainly elevator managers and maintenance personnel) confirmed the actual earthquake situation (with or without shaking) by voice message, The elevator operation mode can be selected.
In addition, if the earthquake detection device has failed, even if there is a shake due to the earthquake, even if step ST103 is executed, the elevator user (mainly the elevator administrator and maintenance personnel) By confirming the shaking due to the earthquake, the above-mentioned specific button B is not pressed down, so that it is possible to prevent erroneous return to the normal operation mode.

In the present embodiment, it is necessary to make the administrator know the specific button A and the specific button B in advance as the administrator password button.
When there is no administrator in the elevator during the earthquake operation mode, an audio message in the car, for example, “Earthquake early warning was received, but the seismometer attached to the elevator does not detect an earthquake even after a predetermined time has elapsed. If there was no shaking due to the earthquake, it will return to normal operation.To return to normal operation, press the close button, the open button, and the second floor button at the same time. Will be operated during an earthquake. For operation during an earthquake, press the close button, the open button, and the first floor button at the same time. "
Also, in this case, the elevator user can select the elevator operation mode after understanding the actual earthquake situation (with or without shaking) by voice message. it can.

  As described above, in the present embodiment, in the temporary recovery mode, when a specific button in the elevator car is pressed, the operation mode is shifted to the operation mode during earthquake, the operation of the elevator is stopped, and another elevator car Describes an elevator control device that allows the elevator user to select the operation mode of the elevator after the elevator user understands the situation by returning the elevator to normal operation when the specific button is pressed did.
