However, in the conventional elevator control device disclosed in Patent Document 1, an earthquake cannot be detected while the earthquake detector is determined to be out of order, and maintenance personnel are notified by a failure notification that is made in accordance with the failure determination. Until the site rushes to the site and repairs the failure, there is a problem that the earthquake cannot be normally detected and the control operation during the earthquake cannot be performed.
Here, in order to operate more safely, it is described in Patent Document 1 that the seismic detector is forced to operate during an earthquake while it is determined to be a failure, but in this case, If the failure of the seismic sensor is just a failure, it will be necessary to carry out the operation control during an earthquake that is not necessary originally, and there is a problem that the operation efficiency deteriorates.
As pointed out in Patent Document 1, an electronic seismic sensor having a CPU may break down from a mechanical seismic sensor that mechanically detects an earthquake due to the runaway of the CPU. As mentioned above, it is thought that there are many cases where failure of an electronic seismic detector is detected as described above, and it is impossible to normally detect earthquakes, or to perform unnecessary earthquake control operations. These challenges are serious.

  The present invention has been made to solve the above-described problems, and can detect the occurrence of an earthquake even while an electronic seismic sensor is determined to be out of order. It is an object of the present invention to provide an elevator control device that can perform seismic control operation more appropriately than a control device.

  In the elevator control device according to the present invention, the first seismic detection of an electronic circuit type having an earthquake control operation device for controlling the control operation at the time of an earthquake at the time of an earthquake and a CPU for performing earthquake detection by computer control. And a mechanical second seismic sensing unit that senses an earthquake by a mechanical configuration independently of the first seismic sensing unit, and a failure detection unit that detects a failure of the first seismic sensing unit And when the failure detection means does not detect a failure of the first earthquake sensing means, the earthquake control operation device is based on the earthquake detection result of the first earthquake sensing means. When the earthquake control operation is controlled and a failure of the first earthquake sensing means is detected by the failure detection means, the earthquake time tube is based on the earthquake detection result of the second earthquake sensing means. A structure for controlling the operation.

  The present invention relates to an elevator control device, an earthquake control operation device that controls the control operation during an earthquake when an earthquake occurs, and an electronic circuit type first earthquake detection means having a CPU for performing earthquake detection by computer control. Independent of the first seismic sensing means, mechanical second seismic sensing means for sensing earthquakes with a mechanical configuration, and failure detecting means for detecting a failure of the first seismic sensing means, And when the failure detection means has not detected a failure of the first earthquake sensing means, the earthquake operation control device comprises the earthquake based on the earthquake detection result of the first earthquake sensing means. When controlling the time control operation and detecting the failure of the first earthquake sensing means by the failure detection means, the earthquake time control operation is performed based on the earthquake detection result of the second earthquake detection means. By adopting the control configuration, it is possible to detect the occurrence of an earthquake even while the electronic seismic detector is determined to be out of order, and more appropriately during an earthquake than with a conventional elevator control device. There is an effect that the control operation can be performed.

Embodiment 1 FIG.
1 and 2 relate to Embodiment 1 of the present invention. FIG. 1 is a block diagram showing the overall configuration of the elevator control device, and FIG. 2 is a flowchart showing the operation of the elevator control device.
In the figure, reference numeral 1 denotes a control panel that controls the overall operation of the elevator, and this control panel 1 includes an earthquake control operation device 2 that controls the control operation during an earthquake according to the magnitude of the earthquake when an earthquake occurs. .
The scale of this earthquake is divided into two stages: the extra-low earthquake, which is the smallest earthquake, and the lower earthquake, which is a larger earthquake. For example, if the occurrence of a low earthquake is not detected within one minute after the time control operation is performed, it is determined as safe and the operation is reset to return to the normal operation. On the other hand, when the occurrence of a low earthquake is detected, the scale of the earthquake is infinite, so the operation is suspended after the earthquake control operation in consideration of safety.
The detection of the occurrence of these extra low earthquakes and low earthquakes is performed by the earthquake detector 3, which is an electronic circuit type unit 4 (first earthquake) having a CPU for performing earthquake detection by computer control. Sensing means), a battery 4a for supplying electric power for driving the electronic circuit type unit 4, and a mechanical unit 5 (second seismic sensing unit) for performing earthquake detection by a mechanical configuration.

The electronic circuit unit 4 outputs extra low earthquake detection operation information when detecting the extra low earthquake with a magnitude of earthquake equal to or less than a predetermined magnitude, and the low level of earthquake greater than the predetermined magnitude is output. When an earthquake is detected, low earthquake detection operation information is output.
Then, the extra low earthquake detection operation information output from the electronic circuit type unit 4 is transmitted through the electronic circuit type unit extra low earthquake information input means 6 a provided in the control panel 1. The low-earthquake detection operation information output from the electronic circuit section 4 is input to the control circuit 1 via the electronic circuit section low earthquake information input means 6b provided in the control panel 1. 2 is input.

The earthquake control operation device 2 that has received the low earthquake detection operation information via the electronic circuit type low earthquake information input means 6b shifts the elevator to the earthquake control operation, and then operates the elevator. To pause. When the operation of the elevator is suspended, the seismic control operation device 2 sends reset command information to the electronic circuit unit 4 via the electronic circuit unit reset means 7 provided in the control panel 1. It outputs and resets the low earthquake detection operation of the electronic circuit type unit 4.
Further, when the special low earthquake detection operation information is received via the special low earthquake information input means 6a for the electronic circuit type part, the earthquake control operation device 2 temporarily shifts the elevator to the earthquake control operation. Thereafter, for example, when no low earthquake detection operation information is input within 1 minute, reset command information is output to the electronic circuit unit 4 via the electronic circuit unit reset means 7 to output the electronic circuit type The extra low earthquake detection operation of the unit 4 is reset and the elevator is returned to normal operation.

The electronic circuit unit 4 is controlled by the CPU as described above, and outputs fault operation information when a fault detection unit (not shown) detects a fault due to the runaway of the CPU. The output fault operation information is input to the seismic control operation device 2 via the electronic circuit type fault information input means 8 provided in the control panel 1.
The failure detection means detects the occurrence of a failure due to CPU runaway or the like, for example, when the thermal runaway of the CPU, the extra low earthquake detection operation information is latched and output by the hardware of the earthquake detector 3, This is performed depending on whether the number of reset command outputs within a predetermined time (for example, within 3 minutes) after the reset command information is output from the electronic circuit type reset means 7 is counted more than a specified number of times (for example, 3 times). (For example, refer to Patent Document 1).

In addition, as described above, the earthquake detector 3 includes the mechanical unit 5 that detects the low earthquake by a mechanical configuration independently of the electronic circuit unit 4, and the mechanical unit 5 includes the mechanical unit 5 described above. When a low earthquake is detected, low earthquake detection operation information is output. The outputted extra low earthquake detection operation information is input to the earthquake control operation device 2 through the mechanical part low earthquake information input means 9 provided in the control panel 1.
The seismic control operation device 2 that has received the low earthquake detection operation information via the mechanical part low earthquake information input means 9 controls the elevator in the event of an earthquake, as detected by the electronic circuit type unit 4. After shifting to operation, the operation of the elevator is suspended. When the operation of the elevator is suspended, the seismic control operation device 2 sends the reset command information to the mechanical unit 5 via the mechanical unit resetting means 10 provided in the control panel 1. Output and reset the low earthquake detection operation of the mechanical unit 5.

A monitoring panel 11 for monitoring the status of the elevator is provided in a supervisory room inside the building where the elevator is installed and a monitoring center of a maintenance company provided outside the building. The extra low earthquake detection operation information and the low earthquake detection operation information input to the control operation device 2 are sent to the monitoring panel 11 as earthquake detection operation information via the earthquake information input / output means 12 provided in the control panel 1. be delivered. Further, the failure detection information input to the earthquake control operation device 2 is distributed to the monitoring panel 11 via the failure information input / output means 13 provided in the control panel 1.
Upon receiving the distribution of the earthquake detection operation information or the failure detection operation information, the monitoring panel 11 performs notification such as displaying such information or sounding the sound.

The flowchart of FIG. 2 shows the operation of the elevator control apparatus in this embodiment.
First, in step S1, the seismic control operation device 2 detects whether or not a failure operation of the electronic circuit unit 4 has been detected, that is, the electronic circuit unit via the electronic circuit unit failure information input means 8. It is confirmed whether or not failure operation information is output from the expression unit 4.
In this confirmation, when it is confirmed that the failure operation of the electronic circuit unit 4 is not detected, the process proceeds to step S2, and the seismic control operation device 2 is configured so that the electronic circuit unit 4 is low. It is confirmed whether or not an earthquake is detected, that is, whether or not low-earthquake detection operation information is output from the electronic circuit type unit 4 via the electronic circuit type unit low earthquake information input means 6b. .
If it is confirmed in this confirmation that the electronic circuit type unit 4 has detected a low earthquake, the process proceeds to step S5, and the seismic control operation device 2 shifts the elevator to the seismic control operation. After that, as described above, the operation of the elevator is suspended, and reset command information is output to the electronic circuit unit 4 to reset the low earthquake detection operation of the electronic circuit unit 4. Then, step S9 is reached, and the series of operation flow ends.

If it is confirmed in step S2 that the electronic circuit unit 4 has not detected a low earthquake, the process proceeds to step S3. Whether or not a low earthquake is detected, that is, whether or not extra low earthquake detection operation information is output from the electronic circuit unit 4 via the electronic circuit type unit extra low earthquake information input means 6a. Confirm.
In this confirmation, when it is confirmed that the electronic circuit type unit 4 has detected the extra low earthquake, the process proceeds to step S5, and the earthquake control operation device 2 shifts the elevator to the earthquake control operation. . After that, as described above, when the low earthquake detection operation information is not input within one minute after the shift to the earthquake control operation, the electronic circuit part resetting means 7 is used to input the electronic The reset command information is output to the circuit unit 4 to reset the extra low earthquake detection operation of the electronic circuit unit 4, and the elevator is returned to normal operation. Then, step S9 is reached, and the series of operation flow ends.

  If it is confirmed in step S3 that the electronic circuit unit 4 has not detected an extra low earthquake, the process proceeds to step S4, and the elevator continues normal operation. And it returns to step S1 and repeats a series of operation | movement flows.

On the other hand, when it is confirmed in step S1 that the failure operation of the electronic circuit unit 4 is detected, the process proceeds to step S6, and the earthquake control operation device 2 determines that the failure information The failure operation information is output to the monitoring panel 11 via the input / output means 13, and the monitoring panel 11 receiving the failure operation information indicates that a failure has occurred in the electronic circuit unit 4 of the earthquake detector 3. The maintenance staff goes to the site to investigate the cause and perform recovery work.
And it progresses to step S7, and the said earthquake time control operation apparatus 2 determines whether the said mechanical part 5 has detected the low earthquake, ie, the low earthquake information input means 9 for the said mechanical part, It is checked whether low earthquake detection operation information is output from the mechanical unit 5.

In this confirmation, when it is confirmed that the mechanical unit 5 has detected a low earthquake, the process proceeds to step S5, and the seismic control operation device 2 shifts the elevator to the seismic control operation. After that, the operation of the elevator is stopped, and reset command information is output to the mechanical unit 5 via the mechanical unit resetting means 10 provided in the control panel 1 to thereby output the mechanical unit. Reset the 5 low earthquake detection operation. Then, step S9 is reached, and the series of operation flow ends.
On the other hand, if it is confirmed in step S7 that the mechanical unit 5 has not detected a low earthquake, the process proceeds to step S8, and the elevator continues normal operation. And it returns to step S1 and repeats a series of operation | movement flows.

  In the elevator control apparatus configured as described above, an electronic circuit type unit which is an electronic circuit type first earthquake detection unit having a CPU for performing earthquake detection by computer control, and a first earthquake detection unit, Independently comprises a mechanical part which is a mechanical second seismic sensing means for sensing earthquakes by a mechanical configuration, and a fault detecting means for detecting a failure of the first seismic sensing means. If the failure of the first earthquake sensing means is not detected, the control operation device controls the control operation during the earthquake based on the earthquake detection result of the first earthquake sensing means, and the failure detection means When a failure of the earthquake detection means is detected, the control of the seismic control operation is performed based on the earthquake detection result of the second earthquake detection means, while the electronic earthquake detector is determined to be broken. Even in the earthquake It is possible to sense the raw, it can be performed more appropriately seismic control operation as compared with the conventional elevator controller.

In addition, if an attempt is made to detect multiple levels of earthquakes using only a mechanical earthquake detector, the equipment will be large and expensive, but an electronic circuit type earthquake detector will detect multiple levels of earthquake detection. Even if it is configured to do so, the size and cost of the apparatus will not increase greatly.
Therefore, the electronic circuit part that is the first earthquake detection means can detect earthquakes of multiple levels of extra low earthquakes and low earthquakes, and the mechanical part that is the second earthquake detection means is a two-stage earthquake. The earthquake control operation device shall be configured to control the earthquake control operation according to the magnitude of the earthquake, so that only low-earthquake earthquakes with a large impact can be detected. In addition, while controlling the size of the seismic detector as a whole, it is possible to control operation at the time of earthquake according to the magnitude of the earthquake in multiple stages, and the mechanical part that can detect the low earthquake, which has a large impact, is an electronic circuit type By providing a backup for use in the event of a part failure, even if a fault occurs in an electronic circuit type part and control operation during an earthquake according to the magnitude of the earthquake is not possible, a low earthquake with a large impact will occur This is the machine Senses in parts, it is possible to carry out a seismic control operation.

In addition, here, the earthquake scale is divided into two stages, extra low earthquake and low earthquake, and the control operation at the time of earthquake is performed. However, it is divided into all three stages including a high earthquake as a larger earthquake than a low earthquake. However, the present invention can be applied.
Further, since the seismic detector is provided with the electronic circuit type part and the mechanical type part, the life of the seismic sensor as a whole can be extended.

Embodiment 2. FIG.
In the first embodiment described above, when the CPU of the electronic circuit type unit that performs earthquake detection by computer control causes a thermal runaway, this is detected and fault operation information is output, and the fault operation is detected. In some cases, the seismic sensing is performed by the mechanical part that performs seismic sensing by a mechanical configuration instead of the electronic circuit type part, and the control operation at the time of earthquake is performed, but the second embodiment described here is the implementation described above. In addition to the configuration and operation of the first embodiment, even when it is detected that an abnormality has occurred in the battery that supplies power to the electronic circuit unit, and power cannot be supplied from the battery to the electronic circuit unit. The fault operation information is output and the seismic detection is performed not by the electronic circuit type unit but by the mechanical type unit so that the control operation at the time of the earthquake is performed.

That is, the electronic circuit unit 4 that performs earthquake detection by computer control requires electric power to perform the earthquake detection operation. In normal times, the electric circuit unit 4 obtains this electric power from a main power supply that supplies driving power for the elevator. An earthquake detection operation is performed, and this main power supply is generally provided by power purchased from a power company.
However, from the viewpoint of energy saving, when the elevator is not used, the power supply from the main power supply is cut off to be in a standby state, and the standby state in which the power supply from the main power supply is cut off is becoming common. It is inconvenient that when an earthquake occurs, it is not possible to perform an earthquake sensing operation and subsequent control operation during an earthquake. Moreover, there is a similar inconvenience when the power supply from the power company is cut off due to a power failure or the like.
In order to eliminate this inconvenience and to enable an earthquake detection operation even when the power supply from the main power source to the electronic circuit unit 4 is cut off, the power supply from the main power source is cut off. The main purpose of providing the battery 4a is to supply electric power to the electronic circuit unit 4 when the battery 4a is present.

Therefore, in the second embodiment described here, the battery 4a is discharged because the standby state in which the power supply from the main power source is cut off continues for a long time, and is necessary for the operation of the electronic circuit unit 4. In the case where an abnormal voltage supply cannot be supplied, or in the case where an abnormality occurs in the power supply to the electronic circuit unit 4, this is detected by a power supply abnormality detection means (not shown). When an abnormality is detected by the power supply abnormality detecting means, the electronic circuit type unit 4 is configured to output failure operation information.
The other configurations and operations are the same as those in the first embodiment, and the fault operation information output from the electronic circuit unit 4 is controlled by the earthquake control operation via the electronic circuit unit fault information input means 8. Input to the apparatus 2 and operation is performed according to the operation flow of FIG. When an abnormality has occurred in the battery 4a, the seismic detection is performed by the mechanical unit 5 instead of the electronic circuit unit 4, and the seismic control operation is performed.

  In the elevator control apparatus configured as described above, in addition to the effects similar to those of the first embodiment, the first earthquake detection is performed when the power supply from the main power supply is cut off. A battery for supplying electric power for driving the electronic circuit type unit, and a power supply abnormality detecting means for detecting that an abnormality has occurred in the power supply to the first earthquake sensing means. When the detecting means detects that an abnormality has occurred in the power supply to the first earthquake sensing means, the failure detecting means detects the failure of the first earthquake sensing means, thereby supplying power from the main power source. If the battery is discharged due to the standby state being shut off for a long time and the voltage necessary for the operation of the electronic circuit unit cannot be supplied, etc. Restore main power Even when you sometimes have become by the electronic-circuit part is impossible to seismic sensor, performs a seismic sensor in more of a mechanical part, it is possible to perform the seismic control operation.

It is a block diagram which shows the whole structure of the elevator control apparatus in Embodiment 1 of this invention. It is a flowchart which shows operation | movement of the elevator control apparatus in Embodiment 1 of this invention.
