Is a second non-contact detection device that detects the

Reference numeral 6 denotes a contact detecting device provided at an edge of the door of the door device 3 on the door closing side, which is operated by being displaced by contacting foreign matter at the entrance 2. And a control unit to be described later, a station on the car which performs necessary information by serial communication, 8 is a notifying means provided in the car 1 for notifying necessary announcements, and 9 is installed in a machine room (not shown) of an elevator. Control device,
It is composed of the following devices.

That is, an operation control means 10 formed by a microcomputer for mainly controlling the operation of the entire elevator, and a failure automatic detection for automatically detecting a failure of the first non-contact detection device 4 and the second non-contact detection device 5 Means 11, a door closing speed adjusting means 12 for adjusting the door closing speed of the door of the door device 3, an external notifying means 13 for notifying the outside when a failure occurs, a first non-contact detecting device 4, and a second non-contact detecting device 5. And a car information transmitting means 15 for performing serial communication with the on-car station 7.

Each device such as the operation control means 10 constituting the on-car station 7 or the control device 9 is all constituted by software in a microcomputer. In addition, the first non-contact detection device 4 and the second non-contact detection device 5 may be provided together, or only one of them may be provided.

In the elevator device constructed as described above, when the car 1 opens and closes the door of the door device 3 in response to the call, the contact detecting device 6, the first non-contact detecting device 4, and the second When the non-contact detection device 5 operates, it is determined that the passenger is passing through the entrance 2. Thereby, if the door of the door device 3 is performing the door closing operation, the door is driven to open by the door device 3.

A procedure for automatically detecting the presence / absence of the first non-contact detection device 4 and the second non-contact detection device 5 in the elevator device configured as described above will be described with reference to a flowchart shown in FIG. That is, since a plurality of types of non-contact detection devices are installed as shown in FIG. 1, it is necessary to determine which type of non-contact detection device is installed.

For this purpose, there is a method in which the presence or absence of a non-contact detection device is set in advance by using a parameter or the like. For this reason, here, it was set as the structure which an elevator apparatus can automatically detect the presence or absence of a non-contact detection apparatus. That is, regardless of whether the non-contact detection device is installed or not, the calculation according to the flowchart of FIG. 2 is performed to determine whether the non-contact detection device is installed and whether or not the non-contact detection device is present based on the fact that the non-contact detection device is operated. To judge.

That is, when the car 1 answers the call in step 101 by the operation of the control device 9, step 102
Proceeding to, when either one of the first non-contact detection device 4 and the second non-contact detection device 5 operates, the process proceeds to step 103;
Proceed to. In step 103, if either of the above two operates continuously three times, the process proceeds to step 104, and if either of the two does not continuously operate three times, the process proceeds to step 106.

Then, in step 104, it is determined that the non-contact detection device is installed, and the process proceeds to step 105, where S = 1 is set. Also, in step 106, it is not determined that the non-contact detection device is installed, and the process proceeds to step 107, where S = 0 is set.

A procedure for automatically detecting a failure of the first non-contact detection device 4 and the second non-contact detection device 5 in the elevator device configured as described above will be described with reference to a flowchart shown in FIG. Note that this failure detection needs to be performed for each installed non-contact detection device, but only one non-contact detection device will be described here. That is, the operation of the control device 9 causes step 201 to proceed.
, The counter N is cleared to 0 only when the power of the elevator apparatus is turned on.

Then, the process proceeds to step 202, and if S = 1 in step 105 of the flowchart of FIG. 2, the process proceeds to step 203. If not, the process proceeds to step 206.
Proceed to. In step 203, each time the car 1 responds to the call, it is determined whether or not the contact detection device 6 has operated each time the door of the door device 3 opens and closes. If not, the process proceeds to step 206; Proceed to 204.

If the non-contact detection device operates in step 204, the process proceeds to step 206, and if not, the process proceeds to step 205. In addition, when the contact detection device 6 and the non-contact detection device are installed side by side, if a passenger gets on or off while the door of the door device 3 is normally closing the door, the non-contact detection device 6 is turned off before the contact detection device 6 operates. The contact detection device operates. As a result, since the door of the door device 3 during the door closing operation is turned over, the failure of the non-contact detection device is determined because the non-contact detection device is not operating at this time.

In step 205, if the non-contact detection device was not operating when the contact detection device 6 was operated last time, the process proceeds to step 206, and if the non-contact detection device is operating, the process proceeds to step 207. Step 2
At 07, N is counted up and the routine proceeds to step 208,
If N ≧ 5, the process proceeds to step 209, where it is determined that the non-contact detection device has failed. In step 206, the counter N is cleared to zero.

FIG. 4 shows an operation procedure after automatically detecting a failure of the first non-contact detecting device 4 and the second non-contact detecting device 5 in the elevator device configured as described above.
This will be described with reference to the flowchart shown in FIG. That is, in step 301, the door device 3 is controlled by the operation of the control device 9 via the door closing speed adjusting means 12 so that the door closing speed becomes slower than usual. Is activated, and an announcement that calls attention to the passengers in the car 1 is notified. For example, "The door closes. Please be careful." Next, the routine proceeds to step 303, where the external notification means 13 is energized, and the occurrence of a failure is notified to the outside such as the manager's office and the disaster prevention center.

Further, the failure automatic recovery detecting means 14 for automatically detecting the recovery of the failure of the non-contact detection device in the elevator apparatus configured as described above detects that the non-contact detection device has automatically recovered. Figure 5 shows the operation procedure
This will be described with reference to the flowchart shown in FIG. That is, in step 401, the counter Nc is cleared to 0 only when the power of the elevator device is turned on by the operation of the control device 9.

Then, the routine proceeds to step 402, where car 1
Each time the door of the door device 3 opens and closes in response to the call, it is determined whether or not the failure automatic detection means 11 has detected a failure in the non-contact detection device. The process proceeds to step 403 if a failure has been detected. If the non-contact detection device is not operating in step 403, the process proceeds to step 405, and if the non-contact detection device is operating, the process proceeds to step 404.

Next, at step 404, when the car 1 responded to the call last time and the door of the door device 3 opened and closed in response to the call, it was determined whether or not the non-contact detection device was operated. If not, step 4
Proceeding to step 05, if the non-contact detection device is operating, proceed to step 406 to count up Nc. Next, proceeding to step 407, if Nc ≧ 5, proceeding to step 408, it is determined that the non-contact detection device has recovered from the failure, and the failure automatic recovery detection means 14 operates. In step 405, the counter Nc is cleared to 0.

When it is determined that the non-contact detection device has recovered from the failure in this way, the operation of the failure automatic recovery detection means 14 causes the door device 3 in the flowchart of FIG. Is controlled, the car 1 is automatically shifted to normal operation without lowering the door closing speed than usual and notifying the passengers in the car 1 of an announcement alerting them.

The structure of the non-contact detecting device is generally more complicated than that of the contact detecting device 6, and the non-contact detecting device is likely to malfunction due to the influence of the surrounding environment. Under such circumstances, the failure of the non-contact detection device can be easily detected by determining the operation status of the non-contact detection device with respect to the operation of the contact detection device 6. Then, by performing the failure recovery through the failure detection of the non-contact detection device, the normal operation of the contact detection device 6 and the non-contact detection device allows the door during opening / closing operation of the door device to be properly reversed. Therefore, it is possible to prevent a passenger from being caught in the door.

Further, the door device 3 is controlled by the door closing speed adjusting means 12 through the OFF failure detection of the non-contact detecting device to make the door closing speed slower than usual, or the notification means 8 is energized. Then, an announcement that calls attention to the passengers in the car 1 is notified. Therefore, even in the event of an OFF failure of the non-contact detection device, the function of the contact detection device 6 can prevent a passenger from being immediately caught in the door, and the car 1 can continue to operate without trouble for the passenger. can do.

When it is determined that the non-contact detection device has recovered from the failure through the operation of the automatic failure recovery detection means 14 when the non-contact detection device is turned OFF, the car 1 automatically operates normally. Is moved to Therefore, it is possible to reduce the number of operations required by the administrator when the non-contact detection device recovers from the failure.

Embodiment 2 By applying the embodiment shown in FIGS. 1 to 5, it can be easily configured as described below. That is, when the first non-contact detection device 4 and the second non-contact detection device 5 detect an abnormality in which the contact detection device 6 operates and the number of consecutive occurrences of the abnormality exceeds a predetermined value, The control device 9 is configured to operate at an abnormal time.

In the elevator device configured as described above, the first non-contact detecting device 4 and the second non-contact detecting device 5, that is, the continuous occurrence of the OFF fault of the non-contact detecting device causes the OFF fault of the non-contact detecting device. Is automatically detected in a short period of time without being neglected. Then, through this failure detection, an OFF failure of the non-contact detection device can be promptly and accurately dealt with, and the abnormal state of the elevator can be quickly eliminated.

The non-continuous OFF of the non-contact detection device
It is conceivable that, for example, one year after the failures are accumulated over a long period of time, the control device 9 operates abnormally. In such a case, unnecessary abnormal operation of the control device 9 due to a rare malfunction of the non-contact detection device for a long period can be eliminated. Therefore, it is possible to save the trouble of the elevator manager and the like due to the abnormal operation of the control device 9 which is falsely reported.

Embodiment 3 By applying the embodiment shown in FIGS. 1 to 5, it can be easily configured as described below. That is, the failure automatic detection means 11 for detecting a failure of the non-contact detection device, and after the operation of the failure automatic detection means 11, the number of consecutive operations of the non-contact detection device during the operation of the contact detection device 6 exceeds a predetermined value. And a control device 9 having an automatic failure recovery detecting means 14 which operates when the failure occurs.

In the elevator apparatus configured as described above, when it is determined that the non-contact detection device has recovered from the failure through the operation of the automatic failure recovery detection means 14 when the non-contact detection device is turned OFF. , The car 1 is automatically shifted to normal operation. Therefore, it is possible to reduce the number of operations required by the administrator when the non-contact detection device recovers from the failure.

It is also conceivable that the recovery from discontinuous failures of the non-contact detection device is integrated over a long period of time, and the number of times of recovery of the non-contact detection device reaches a predetermined value, thereby detecting the automatic recovery from the failure. In such a case, it is possible to eliminate the automatic failure recovery detection due to the integration of the rare failure recovery of the non-contact detection device for a long time. That is, it is possible to eliminate a decrease in detection accuracy in which rare failure recovery of the non-contact detection device is accumulated and automatic failure recovery is detected.
