The CPU 28 changes setting of the automatic inspection time in the time zone selected by the selection means 38 and stores the setting in the memory 30.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an automatic elevator inspection apparatus for automatically operating an elevator by setting a time zone in advance and performing various inspections.

[0002]

2. Description of the Related Art Elevators require periodic inspections. Conventionally, elevator automatic inspection devices have been used which automatically perform these inspections. For example, JP
JP-A-245171 also discloses an example of such an automatic elevator inspection apparatus.

FIG. 8 is a block diagram showing the configuration of the above-described conventional automatic elevator inspection apparatus. In FIG.
The elevator car 10 is connected to a counterweight 12 via a rope, and is driven by an electric motor 14. The operation of the elevator including the car 10, the weight 12, the electric motor 14, and the like is controlled by the elevator control device 16. The elevator control device 16 is connected to a hall device 18 provided on a wall surface or the like outside the car 10 and having a push button or the like. In addition, basket 10
Also, a signal from a car device such as a push button provided inside the car 10 is input. The elevator control device 16 has a control CP to which signals from push buttons and the like provided in the hall devices 18 and the car devices in the car 10 are input.
U20 is provided, and a memory 22 for storing elevator operation information and the like is connected. Also, the CPU 20 includes:
A drive control circuit 24 for controlling the drive of the electric motor 14 is also connected.

The elevator control device 16 is connected to automatic inspection means 26 for automatically inspecting the elevator. The automatic inspection means 26 is also provided with a CPU 28 and a memory 30 connected thereto. Memory 30
Stores information such as elevator operation information similar to that of the memory 22, and information such as an automatic inspection time of the elevator. The automatic inspection device of the elevator is also connected to the maintenance center device 34 via the exchange 32, and data such as the time at which the automatic inspection is performed is automatically inspected by the telephone line from the maintenance center device 34 via the exchange 32. It is sent to the means 26.

At a predetermined inspection time, the elevator automatic inspection means 26 checks whether the door of the car 10 is closed, whether a call is generated by the hall device 18 or a push button in the car 10, and the like. Then, the lights in the car 10 are turned off and the presence or absence of the call is confirmed again. If a call is confirmed in these series of confirmation operations, it means that there is an elevator user, and the automatic inspection operation is interrupted.

As described above, in the above-described conventional example, if it is determined that there is a user even during the automatic inspection, the automatic inspection operation is interrupted, so that the user can use the elevator as usual. Can be.

[0007] Such automatic inspection of the elevator can be performed by remote control from the maintenance center device 34, or can be performed in a time zone previously stored in the memory 30 as described above. During such automatic inspections,
A time period during which there is no user is determined in advance from a survey on the use status of the elevator and the like, and automatic inspection is performed during this time period.

[0008]

However, in the above-described conventional elevator automatic inspection apparatus, the elevator automatic inspection time is set in advance by estimating the time when no elevator user is present. Due to changes in the usage conditions of elevators, changes may occur in the elevator use time zone, and users may be present during the scheduled automatic inspection time zone, and it is difficult to notice this. However, there is a problem that it is difficult to correct the time period of the automatic inspection operation.

There is also a problem that the automatic inspection is interrupted due to the presence of a user during a preset automatic inspection time zone, and it becomes difficult to perform an effective automatic inspection operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an automatic elevator inspection system capable of promptly changing an elevator automatic inspection time zone in accordance with a change in elevator use conditions. It is to provide a device.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an automatic elevator inspection apparatus for automatically operating an elevator and performing various inspections, wherein the automatic inspection apparatus sets an automatic inspection time of the elevator. Time setting means, call storage means for storing the number of calls from the user, comparison means for outputting a setting change signal when the number of calls at the set automatic inspection time exceeds a predetermined value, and Setting change means for changing the set automatic inspection time according to the setting change signal.

In the above automatic elevator inspection apparatus, the storage means stores the number of calls for each day of the week, day, and hour.

[0013] Further, in the automatic elevator inspection apparatus, the number of calls is grasped in four categories of 0, 1, 2, and 3 or more.

[0014] The automatic inspection device for an elevator may include:
A transmission means for transmitting the data of the number of calls to the maintenance center by the setting change signal is further provided.

[0015]

Embodiments of the present invention (hereinafter referred to as embodiments) will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the construction of an automatic elevator inspection apparatus according to the present invention. The same elements as those in FIG. The automatic inspection means 26 is provided with a memory 30 as in FIG. 8, and stores elevator operation information, a time zone of automatic elevator inspection and the like as in FIG. The time zone of the automatic inspection of the elevator is set by the CPU 28 or by an instruction sent from the maintenance center device 34 to the automatic inspection means 26 via the exchange 32, and
0 is stored. Here, the CPU 28 or the maintenance center device 34 and the memory 30 constitute an automatic inspection time setting means according to the present invention.

The memory 30 also stores the number of occurrences of elevator calls. FIG. 2 shows the memory 3
An example of a data format of the number of occurrences of a call stored in 0 is shown. In FIG. 2, the number of occurrences of calls is recorded and stored in units of 15 minutes. The call is counted as the number of times the push button of the hall device 18 of the elevator or the push button provided on the car device inside the car 10 is pressed. In the example shown in FIG. 2, the number of calls counted in this way is represented by 2 bits every 15 minutes.
For example, the first 15 minutes are two bits D0 and D1, the next 15 minutes are D2 and D3, and the next 15 minutes are D4 and D4.
In D5, the last 15 minutes are represented by D6 and D7, and one hour is recorded by one byte. With such a configuration, 15
The number of calls that occurred per minute is D0, D1 when there are 0 calls
Etc., 00 is recorded, and in the case of one case, 01 is recorded, and 2 is recorded.
10 is recorded in the case of a case, and 11 is recorded in the case of three or more cases. As a result, the number of calls that occurred in 15 minutes can be determined as 0, 1, 2, or 3 or more, but during the time period when the number of calls is 3 or more, automatic elevator inspection is not performed. Therefore, it is sufficient for the present invention to be able to determine this degree.

In this way, one byte of memory is allocated to one hour, and the number of calls in each period such as one hour, one day, one week, one month, etc. is recorded every 15 minutes.
This data is stored in the memory 30. Therefore, the memory 30 also functions as a call storage unit according to the present invention.

FIG. 3 shows an example of the measured value of the number of elevator calls. In FIG. 3, from 5:00 to 8:00 from March 1 to March 7, and from 18:00 to 20:30
The actual value of the number of calls every 15 minutes up to the minute is measured and recorded. Of these measured values, for example, 3
FIG. 4 shows an example in which the values from 6:00 to 7:00 on the second day of month 2 are stored in the memory 30 in the format shown in FIG. 3
The number of calls from 6:00 to 6:15 on month 2 is 0, and therefore, data 00 is recorded in the two bits D0 and D1 corresponding to this time. Also, from 6:15 am
Since the number of calls until 2:30 is two, data 10 is stored in the corresponding two bits D2 and D3. Further, since the number of calls from 6:30 to 6:45 is four, data 11 representing three or more is stored in D4 and D5. Since the number of calls from 6:45 to 7:00 is eight, data 11 is stored in D6 and D7 in the same manner. By recording the number of calls every 15 minutes in this way, the number of calls for 24 hours a day can be recorded in a 24-byte memory.

In FIG. 5, the number of daily calls is recorded every 15 minutes as shown in FIG. 4, and the logical sum of data in the same time zone is calculated over one month. Is shown. As described above, by calculating the logical sum of the number of calls every 15 minutes, it is possible to obtain data indicating at what time of the day a call is generated or not during a month. it can. Therefore, the comparison means 36 provided in the automatic inspection means 26 shown in FIG.
8 or the maintenance center device 34 determines whether the number of calls during the automatic inspection time of the elevator stored in the memory 30 exceeds a predetermined value.

For example, if the automatic inspection time is set between 20:15 and 20:30 (corresponding to D2 and D3) shown in FIG. Is 01, which is actually 10
(2), the comparing means 36 outputs a setting change signal for urging the user to change the setting of the automatic inspection time, assuming that the number of calls at the automatic inspection time exceeds a predetermined value. When the CPU 28 receives this setting change signal, the CPU 28
Instructs the selection means 38 to select an appropriate time zone as the automatic inspection time. In the selection means 38, the CP
Based on the instruction from U28, stored in the memory 30;
From the data of the number of calls for one month shown in FIG. 5, a time zone in which the data is 00, that is, the number of calls is 0, is selected.
The central time in the continuous time zone is selected as a new automatic inspection time, and the selection result is output to the CPU 28. For example, in the example shown in FIG. 5, since the time from 21:15 to 4:45 in the next morning, the data 00 represents the number of calls 0, the data 00 represents the center of the time zone of the continuous data 00. Hour and thirty minutes is selected, and
Is output to

The CPU 28 determines the time zone selected by the selection means 38 as a new automatic inspection time, and changes the automatic inspection time stored in the memory 30. As described above, the CPU 28, the comparison unit 36, and the selection unit 38 constitute a setting change unit according to the present invention.

Next, FIG. 6 shows an example in which data on the number of calls is extracted for each day of the week and compared in the same time zone.
From such data, it is possible to determine which day of the week has the least number of calls in the same time zone. Thereby, even when it is not possible to obtain a time zone with a small number of calls in the data of the number of daily calls for one month shown in FIG. 5, a time zone with a small number of calls can be found by decomposing each day. It is more likely that you can. Therefore, even if the selecting means 38 cannot find a time zone in which the automatic inspection time can be set from the data of the total number of calls for one month shown in FIG. It is possible to select a set time from the number-of-calls data decomposed into and output it to the CPU 28.

As described above, when the setting of the automatic inspection time of the elevator is changed, the CPU 28
The set time before the change and the set time after the change are transmitted to the maintenance center device 34 via the control unit 2. Thereby, the engineer in charge of maintenance and inspection can know the change of the automatic inspection time.

The automatic inspection time can be changed by selecting means 3
It is not limited to the time zone selected by 8. When the setting change signal is output from the comparing means 36, the fact is transmitted from the CPU 28 to the maintenance center device 34, and based on this, a technician in charge of maintenance and inspection remotely updates the CPU 28 from the maintenance center device 34. It may be configured to instruct the setting of the automatic inspection time. At this time, the data stored in the memory 30 and corresponding to FIG.
The data may be sent from the server 28 to the maintenance center device 34 and used as data for technician judgment. In this case, the CPU 28 constitutes a transmitting unit according to the present invention.

It is preferable that the data shown in FIG. 5 or FIG. 6 described above is updated sequentially or weekly.

FIG. 7 shows a flow of an operation for setting an automatic inspection time in the elevator automatic inspection device according to the present invention shown in FIG. In FIG. 7, when the setting change signal is output from the comparing means 36 to the CPU 28, the selecting means 38
It is determined whether or not there is a time zone in which there is no user in the data of the number of calls shown in FIG.
When there is no user, that is, when the 2-bit data is 00
If there is a certain time zone, the center of the time zone is selected as the automatic inspection time.
8 and the CPU 28 sets a new automatic inspection time (S2).

On the other hand, if there is no time zone in which there is no user in S1, the selecting means 38 further determines from the call count data for each day of the week as shown in FIG. It is determined whether there is a time zone (S
3).

Here, if there is a time zone where there is no user, a new time zone is set as the automatic inspection time by the operation of S2.

In S3, if there is no time zone of 00 as the data of the number of calls, for example, the comparing means 36
By previously setting the predetermined threshold value in (1) to be large (for example, 11), it is possible to set the time zone of data 01 or 10 in the data of FIG.

Further, when the number of calls exceeding a predetermined threshold value in the comparing means 36 is stored in the daily data shown in FIG. 5 or the data for each day of the week shown in FIG. Is used so frequently that it is not suitable for the automatic inspection operation, so that it is transmitted from the CPU 28 to the maintenance center device 34 that the automatic inspection time cannot be set (S4).

As described above, when the information indicating that the automatic inspection time cannot be set is transmitted, a technician in charge of maintenance and inspection takes appropriate measures.

[0033]

As described above, according to the present invention,
If a call occurs during the pre-set elevator automatic inspection time period and automatic inspection cannot be performed, select a time period during which elevator calls do not occur from the data on the number of calls accumulated up to that point. Since the setting of the automatic inspection time of the elevator can be changed during the time period, the time period of the automatic inspection operation can be quickly set according to the use condition of the building.

Also, since the data of the number of calls is grasped in four units of 0, 1, 2, and 3 or more every 15 minutes, the number of calls can be grasped with a small number of memory bits. Becomes possible.

Also, since the data of the number of calls can be transmitted from the automatic inspection device side of the elevator to the maintenance center device side,
The engineer in charge of maintenance and inspection can easily grasp the usage status of the elevator, and can change the setting of the automatic inspection time as needed.
