Japanese Unexamined Patent Publication No. 2019-43751

On the other hand, the remote diagnosis operation interrupts the operation when an elevator call is generated by the user during the execution, and resumes when the response to the call is completed. Therefore, if a call occurs during the door diagnosis operation and the operation is interrupted, the door opening / closing operation on all floors may not be completed within a predetermined time.

In such a case, the door diagnosis operation must be re-executed from the beginning, resulting in poor processing efficiency. Therefore, it is ideal to execute the door diagnosis operation without interruption as much as possible. However, when the building becomes high-rise and the number of floors increases, the execution time of the door diagnostic operation becomes long, and during that time, the elevator is called by the user and the probability that the door diagnostic operation is interrupted increases. there were.

The present invention has been made in view of the above circumstances, and is an elevator remote diagnosis method and an elevator for efficiently executing a door diagnosis operation for remotely diagnosing a door opening / closing operation with respect to an elevator installed in a building. The purpose is to provide a remote diagnostic device.

According to the elevator remote diagnosis method of the embodiment for achieving the above object, the remote diagnostic device that executes the door diagnosis operation for remotely diagnosing the door opening / closing operation on each floor of the elevator installed in the building is When the execution timing of the door diagnosis operation arrives, the normal operation of the elevator is executed for a certain period of time, and the door open / closed state information of the floor where the car opens / closes the door due to the call generated within the certain time is recorded, and the constant The car that opened due to the call generated in time is closed by the user's operation, the reverse door is opened by the user's operation during the door closing operation, or the car door is safe during the door closing operation. When the inverted door is opened by the operation of the device, the door open / closed state information of the floor is not recorded, and after the certain time elapses, the door diagnosis operation is switched to, and the door open / closed state information is not recorded within the certain time. The door opening / closing operation of the car is performed on all floors.

The whole view which shows the structure of the elevator system using the remote diagnostic apparatus by one Embodiment. A flowchart showing the operation of the remote diagnostic apparatus according to the embodiment.

Hereinafter, the elevator system according to the embodiment of the present invention will be described with reference to the drawings. The elevator system according to the present embodiment remotely diagnoses the operating state of each device in the elevator by causing the elevator to automatically perform a diagnostic operation. Hereinafter, the diagnostic operation in which the elevator is automatically executed in order to remotely diagnose the operating state of each device will be described as "remote diagnostic operation".

In remote diagnosis operation, ON / OFF operation diagnosis of the limit switch installed in the hoistway, operation diagnosis of the brake provided in the hoisting machine, landing position diagnosis of the car on each floor, diagnosis of door opening / closing operation And so on.

<Configuration of elevator system using remote diagnostic device according to one embodiment>
The configuration of the elevator system using the remote diagnostic apparatus according to the embodiment of the present invention will be described with reference to FIG. In the present embodiment, the elevator system 1 is connected to the elevator 2 installed in a four-story building via a communication network 3, and is remotely monitored by a remote monitoring center located at a remote location from the building. A center device 4 is provided. The remote monitoring center device 4 holds schedule information for causing the elevator 2 to execute the remote diagnosis operation, and transmits this schedule information to the elevator 2 via the communication network 3.

The elevator 2 is installed in the hoistway 21 upper part of the building, the hoisting machine 22 and the car 24 suspended from the rope 23 hung on the hoisting machine 22, and the elevator 2 is installed in the hoistway 21 upper part. The elevator control device 27 connected via the tail cord 25 and connected to the hoisting machine 22 by a signal line, and the elevator control device 27 and the remote monitoring center device 4 were connected via the communication network 3. It has a remote diagnostic device 28. In addition, at the landings 26-1 to 26-4 on each floor, there are a landing operation panel 261-1 to 261-4 for users waiting for the elevator to perform a landing call operation, and a landing door 262-1 to 262. 4 and are installed. Hereinafter, when it is not necessary to specify which of the platforms 26-1 to 26-4 is the platform 26, the platform 26 will be described. The landing operation panel 261-1 to 261-4 shall be similarly described as the landing operation panel 261, and the landing doors 262-1 to 262-4 shall be similarly described as the landing door 262.

The car 24 is provided with an in-car operation panel 241 and a car door 242 for the user who has boarded the car to perform a destination floor designation operation and a door opening / closing operation.

The elevator control device 27 registers the landing call when the landing call operation is performed on the landing operation panel 261-1 to 261-4, and registers the corresponding car call when the destination floor designation operation is performed on the in-car operation panel 241. And control the operation of each device to answer these registered calls.

The remote diagnosis device 28 acquires the schedule information transmitted from the remote monitoring center device 4, and causes the elevator control device 27 to execute the remote diagnosis operation based on the schedule information. Then, when the execution timing of the operation for diagnosing the door opening / closing operation (hereinafter referred to as the door diagnosis operation) arrives, the normal operation of the elevator 2 is executed for a certain period of time, and the car is called by the call generated within the certain period of time. The door open / closed state information of the floor on which the car door 242 and the landing door 262 opened / closed after the 24 landed was recorded, and after a certain period of time, the door diagnosis operation was switched to, and all the door open / closed state information was not recorded. The car 24 is sequentially landed on the floor, and the door opening / closing operation of the car door 242 and the corresponding landing door 262 is performed.

<Operation of elevator system according to one embodiment>
Next, the operation of the elevator system 1 according to the present embodiment will be described. In the present embodiment, the schedule information of the remote diagnosis operation held in the remote monitoring center device 4 is transmitted to the remote diagnosis device 28 via the communication network 3 and is held. The remote diagnosis device 28 monitors whether or not the execution timing of the remote diagnosis operation has arrived based on the held schedule information of the remote diagnosis operation.

When the execution timing of the remote diagnosis operation arrives, the limit switch ON / OFF operation diagnosis, the brake operation diagnosis provided in the hoisting machine, the landing position diagnosis of the car on each floor, the door opening / closing operation diagnosis, etc. are performed in sequence. Will be executed. In the door diagnosis operation for diagnosing the door opening / closing operation, the door opening / closing operation on all floors is executed under the same conditions (for example, the same opening / closing speed) within a predetermined time (for example, 30 minutes) after the start. It has been agreed. Hereinafter, this predetermined time will be referred to as a door diagnosis operation time limit. The process executed by the remote diagnosis device 28 during the remote diagnosis operation will be described with reference to the flowchart of FIG.

During the remote diagnosis operation, when the execution timing of the door diagnosis operation arrives (“YES” in S1), the elevator control device 27 is made to execute the normal operation for a certain period (for example, about several minutes) (“NO” in S2 → S3). ). This fixed time is set so that it is possible to respond to at least one call, and the total of the execution time of the door diagnosis operation executed thereafter is within the predetermined door diagnosis operation time limit. Will be done.

A landing call or car call operated by the user is registered during normal operation, and the car door 242 and the landing door 262 are automatically operated by the elevator control device 27 on either floor in response to the landing call or car call. When the door is opened / closed with (S4 "YES"), the door open / closed state information of the corresponding floor is recorded (S5). At this time, the car 24 with the door opened is closed by the operation of the operation panel 241 in the user's car, or is reversed by the operation of the user during the door closing operation, or the door is being closed. When the reverse door is opened by the operation of the car door safety device, that is, when the door is not automatically closed by the elevator control device 27 after a predetermined time from the door opening, the door open / closed state information of the floor is not recorded.

For example, a landing call is first generated on the second floor within a certain period of time, and after the car 24 has landed on the second floor and the car door 242 and the landing door 262-2 have been opened, the user who boarded the car operates the car. It is assumed that the car 24 is closed by performing the door closing operation on the board 241. In this case, the door open / closed state information on the second floor is not recorded in the remote diagnostic device 28.

After that, when the user in the car 24 performs an operation to specify the 4th floor as the destination floor on the operation panel 241 in the car, the car 24 moves to the 4th floor and lands, and the car door 242 and the landing door 262 -4 opens the door. Then, the user gets off at the platform 26-4 on the 4th floor, and the car 24 automatically closes when a predetermined time elapses from the opening of the door. In this case, since the door is automatically opened and closed by the elevator control device 27 in the same manner as the door opening / closing operation in the door diagnosis operation, the door opening / closing state information on the fourth floor is recorded in the remote diagnosis device 28. The processes of steps S3 to S5 are repeated until a certain time elapses from the arrival of the execution timing of the door diagnosis operation.

Then, when a certain time elapses after the execution timing of the door diagnosis operation arrives (“YES” in S2), the normal operation is switched to the door diagnosis operation (S6), and the door open / closed state information is recorded within a certain period. The car 24 is landed on a floor that is not on the floor, for example, the first floor, and the door opening / closing operation of the car door 242 and the landing door 262-1 is performed (S7). Then, the door opening / closing state information on the first floor acquired by the door opening / closing operation is recorded in the remote diagnosis device 28 (S8).

At this point, there are floors (2nd and 3rd floors) where the door open / closed status information is not recorded on the serviceable floors (“NO” in S9), so the process returns to step S7 and is the next floor for door diagnosis operation. The car 24 is moved to the second floor, and the door opening / closing operation is performed. In this way, the processes of steps S7 to S9 are repeated until the door open / closed state information of all the serviceable floors is recorded. When the door open / closed state information of all the serviceable floors is recorded, the door diagnostic operation process ends (“YES” in S9). The recorded door open / closed state information on the 1st to 4th floors is transmitted from the remote diagnosis device 28 to the remote monitoring center device 4 as a door diagnosis result in the corresponding time zone.

The door diagnosis operation described above is interrupted when a call by the user's operation occurs during the execution, and is restarted when the response to the call is completed. Further, in the door diagnosis operation, it is agreed that the door opening / closing operation on all floors is executed under the same conditions within the above-mentioned door diagnosis operation time limit. Therefore, when the door diagnosis operation is interrupted due to the occurrence of the call and the response to the call is completed, a certain time has already passed from the start of the door diagnosis operation, and the doors on all floors are within the above-mentioned predetermined time. When it is determined that the opening / closing operation is not completed, the door diagnostic operation is restarted from the beginning.

However, as in the above-described embodiment, the door diagnosis operation is interrupted as much as possible by using the door opening / closing operation when responding to the call generated within the door diagnosis operation time limit as a result of the door diagnosis. It is possible to efficiently execute the door diagnosis operation without causing it to be performed and without deteriorating the convenience of the user.

In a building that performs remote diagnostic operation of an elevator, if a security floor is set that restricts the entry of general users, the door opening / closing operation of the floor is performed with the inside of the car 24 unattended during the door diagnostic operation. Therefore, it is not possible to obtain information on the opening / closing status of the door on the floor. However, the administrator who is permitted to enter the security floor sets the schedule of the door diagnosis operation according to the time when the administrator is surely entered the security floor, and the administrator performs the security during normal operation within a certain period of time from the start. If the entrance to the floor is performed, the door opening / closing status information of the floor can be surely obtained.

In the above-described embodiment, the operating status of the elevator 2 on the day when the door diagnostic operation is not performed is recorded, and the next door diagnostic operation is performed based on the operating status in the same time zone as the fixed time described in step S2. You may change the length of the fixed time used in. For example, when the utilization rate of the elevator 2 in the past time zone exceeds the first threshold value, the fixed time during the next door diagnosis operation is shortened, and the past utilization rate is lower than the first threshold value. If it is less than, the fixed time of the next door diagnosis operation is lengthened. By making such a change, the probability that the call by the user's operation will occur a number of times within an appropriate range within the fixed time is increased, and the efficiency of the door diagnosis operation can be improved more reliably.

Further, in the above-described embodiment, on the floor on which the door opening / closing state information is recorded within the above-mentioned fixed time before or after the door diagnosis operation, the door opening / closing operation under conditions different from those during normal operation, for example, at low speed. The door opening / closing operation may be performed. By performing the processing in this way, the door opening / closing operation is executed under a plurality of non-overlapping conditions on the same floor within the preset door diagnosis operation time limit, and the door diagnosis operation is efficiently executed with high accuracy. be able to.
