DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator apparatus in which wiring between a car call button and a car operation control board is uniformly fixed. The present invention relates to an elevator apparatus capable of changing a correspondence relation of the above.

[0002]

2. Description of the Related Art FIG. 5 is a structural view of a car operating device portion of a conventional elevator apparatus corresponding to a floor on the fifth floor. As shown in FIG. 5, the elevator device 51 includes a car operation control board 6
1 and a car call button board 66. The car operation control board 61 and the car call button board 66 are connected by a plurality of wires.

The car call button board 66 has a plurality of car call buttons c1 to c4 and d1 to d4. In this case, four buttons in each column are arranged in two vertical columns.

The car operation control board 61 includes a car call input section 63, a car call output section 64, a CPU 65, a RAM
66. Each of the car call input section 63 and the car call output section 64 is composed of an 8-bit register from the 0th bit to the 7th bit as shown in FIG.

[0005] The car call input section 63 has a car call button c1 for the 0th bit and a car call button d1 for the first bit.
The second bit is the car call button c2, the third bit is the car call button d2, and the fourth bit is the car call button c2.
The third bit is connected to the car call button d3, the sixth bit is connected to the car call button c4, and the seventh bit is connected to the car call button d4.

[0006] Similarly, the car call output unit 64 also has a 0th bit for the car call button c1, a first bit for the car call button d1, a second bit for the car call button c2, and a third bit for the car call button. The fourth bit is connected to the car call button c3, the fifth bit is connected to the car call button d3, the sixth bit is connected to the car call button c4, and the seventh bit is connected to the car call button d4.

In the case shown in FIG. 5, the floor is on the fifth floor, a car call button c1 corresponds to the first floor, a car call button d1 corresponds to the second floor, a car call button c2 corresponds to the third floor, and a car call. Button d2 corresponds to the fourth floor, and car call button c3 is five.
It corresponds to the floor. Therefore, the car call buttons d3 and c
The fourth, fourth and fifth bits of the car call input unit 63 and the fifth to seventh bits of the car call output unit 64 are not used.

[0008]

The layout of the car call button varies widely depending on the specifications. For example, the same 5
Even in the case of a floor, various layouts of car call buttons are conceivable as shown in FIGS. 7 (a) to 7 (c).

Further, even if the layout is the same, FIG.
As shown in (d) and FIG. 7 (e), there are cases in which there is a skipped floor or an unstopped floor. Even if the layout of the car call buttons is the same, if the assignment of the car call buttons is different, the wiring of each car call button and the car call input section and the car call output section will be different.

For example, when there is a so-called hollow floor, a car call button assignment method as shown in FIG. 8 can be adopted. In the elevator device 51 ′ shown in FIG. 8, the arrangement of the car call buttons c1 to c4 and d1 to d4 on the car call button substrate 66 is the same as that of the elevator device 51 shown in FIG. The correspondence between c1 to c4 and d1 to d4 and the floor is different.

That is, the 0th bit of the car call input section 63 is the car call button c1, the first bit is the car call button d1, the second bit is the car call button d2, and the third bit is the car call button d3. The fourth bit is connected to the car call button c4, and the fifth to seventh bits are not wired.

Similarly, in the car call output section 64, the 0th bit is the car call button c1, the 1st bit is the car call button d1, the 2nd bit is the car call button d2, and the 3rd bit is the car call button. At d3, the fourth bit is connected to the car call button c4, and the fifth to seventh bits are not wired.

As can be seen from the above description, in the conventional elevator apparatus, when the specification shown in FIG. 5 is changed to the specification shown in FIG.
4, connection wiring between c1 to c4 and the car call input unit 63 and the car call output unit 64 needs to be changed. This causes the following problem.

First, the number of types of connection drawings in the design becomes enormous, which increases the design load on the designer.

Second, it takes a long time for a manufacturer to understand a complicated wiring pattern, and a large amount of time is required for a manufacturing operation because wiring is performed using discrete wires.

Third, since the wiring pattern becomes complicated,
Wiring errors are likely to occur.

The present invention has been made in view of such a point, and there is no need to change the connection wiring by changing the assignment of the car call button in accordance with the change of the specification and the like. It is an object of the present invention to provide an elevator apparatus that can adopt modularized cables such as electric wires, reduce the load and time required for design work and wiring work, and prevent occurrence of wiring errors. I do.

[0018]

SUMMARY OF THE INVENTION The present invention provides a car call button board on which a plurality of car call buttons are arranged, a car call button connected to each of the car call buttons, and detecting an input to each of the car call buttons. An input detection unit, a storage unit that stores the correspondence between each of the car call buttons and the floor, and the car call input detection unit that detects an input based on the correspondence stored in the storage unit. A determination unit for specifying the floor corresponding to a car call button.

According to the present invention, the correspondence between the car call button and the floor is stored in the storage section, and the car call input detection section detects the car call based on the correspondence stored in the storage section. Since the floor corresponding to the button is specified by the determination unit, by changing the correspondence between the car call button and the floor stored in the storage unit, there is no need to perform a design change, a wiring change, and the like. It is possible to easily respond to a change in the assignment of the car call button.

The fourth bit is assigned to the car call button a3 and the fifth bit is assigned to the car call button b3.
The bit is connected to the car call button a4, and the seventh bit is connected to the car call button b4. As a result, the car call input unit 13 forms an 8-bit input bit pattern (see FIG. 2) indicating whether or not each car call button has been detected.

Similarly, in the car call output section 14, the 0th bit is the car call button a1, the 1st bit is the car call button b1, the 2nd bit is the car call button a2, and the 3rd bit is the car call button. The second bit is connected to the car call button a3, the fifth bit is connected to the car call button b3, the sixth bit is connected to the car call button a4, and the seventh bit is connected to the car call button b4.

Each car call button a1 to a4, b1 to b4
Can be turned on according to the output from the car call output unit 14.

The RAM 15 has car call buttons a1 to a
4, b1 to b4 and a storage unit for storing the correspondence between the first floor to the fifth floor. In the present embodiment, R
AM15 is each car call button a1-a4, b1-b4
Call input unit 13 based on the correspondence between
And a processing program for creating a corresponding bit pattern from the input bit pattern formed by.

The transmission control CPU 12 controls the car call input unit 1
3 specifies the floor corresponding to the car call button that has detected the input. Transmission control CP of the present embodiment
The U12 creates a corresponding bit pattern from the input bit pattern according to the processing program stored in the RAM 15 and specifies a floor. Details of creation of the corresponding bit pattern will be described later.

Also, the elevator apparatus 1 according to the present embodiment
Has a main control device 20 that is configured separately from the car operation device 10.

The main controller 20 includes a main CPU 25, a second transmission control CPU 21, a second RAM 22, an EEPROM 2
3. Third RAM 24, EPROM 26 and input device 27
have. The main CPU 25 preferably has about 16 to 32 bits.

Transmission control CPU 12 and second transmission control CPU
21 allows data transmission of about 8 to 16 bits to each other.

The second RAM 22 is a readable and writable storage element shared by the main CPU 25 and the second transmission control CPU 21.

The EEPROM 23 is a storage element for storing specification data, and is configured to be electrically erasable. The specification data includes a RAM based on the specification data.
An auxiliary program for creating a processing program stored in the memory 15 is attached.

The third RAM 24 is a readable and writable storage element for storing data.

The EPROM 26 includes a car call button a1.
A4, b1 to b4 and a second storage unit for storing a setting program for setting the correspondence between the first to fifth floors, for example, a program for changing a processing program stored in the RAM 15. I have. This EPROM
26 can be replaced by an electrically erasable flash ROM.

The input device 27 is a maintenance tool or a maintenance switch used for maintenance or adjustment. The input device 27 is configured as a setting input unit for operating a setting program stored in the EPROM 26.

Next, a method of generating a corresponding bit pattern will be described.

As shown in FIG. 3A, the format of the corresponding bit pattern in this embodiment is such that the 0th bit corresponds to the lowest floor, the 1st bit corresponds to the lowest floor + 1st floor, and The bit corresponds to the lowest floor + the second floor, the third bit corresponds to the lowest floor + the third floor, the fourth bit corresponds to the lowest floor + the fourth floor, and the fifth bit corresponds to the lowest floor + the fifth floor. , The sixth bit corresponds to the lowest floor + the sixth floor, and the seventh bit corresponds to the lowest floor + the seventh floor.

Here, for example, in the case of a specification having no hollow floor, the specification data and the accompanying auxiliary program are transmitted from the EEPROM 23 to the transmission control CPU 12 via the second transmission control CPU 21. Transmission control CP
U12 creates a processing program for forming a corresponding bit pattern in accordance with the auxiliary program,
15 is stored.

In this case, the processing program stored in the RAM 15 is a program for creating a corresponding bit pattern in which the fourth bit as the most significant bit corresponds to the car call button on the top floor “fifth floor”.

As a more detailed example, a car call button b2
Corresponds to the first floor, car call button a3 corresponds to the second floor,
The car call button b3 corresponds to the third floor, and the car call button a
FIG. 3B shows a corresponding bit pattern when 4 corresponds to the fourth floor and the car call button b4 corresponds to the fifth floor. FIG.
In the corresponding bit pattern shown in (b), for example, the presence or absence of the input detection of the car call button b4 corresponds to the fourth bit of the corresponding bit pattern. The corresponding bit pattern in this case is to shift the input bit pattern (see FIG. 2) from the car call input unit 13 to the right by 3 bits (0 is inserted for the left 3 bits (5th to 7th bits) that need to be inserted). Obtained by: That is, the processing program in this case has a processing content of “shift the input bit pattern (see FIG. 2) to the right by 3 bits (insert 0 for the left 3 bits (5th to 7th bits) that need to be inserted)”. It is described.

Next, the operation of the present embodiment having such a configuration will be described.

The passengers in the car have car call buttons a1 to a
4, when any one of b1 to b4 is pressed, the transmission control CPU 1
Reference numeral 2 denotes a corresponding bit pattern (see FIG. 3 (FIG. 3) based on a processing program stored in the RAM 15 as described above from the input bit pattern of the car call input unit 13 (see FIG. b) See))
The floor corresponding to the car call button whose input has been detected is specified.

For example, when the car call buttons a3 and a4 corresponding to the second and fourth floors of the car call button are pressed, the corresponding bit patterns obtained from the input bit patterns by the car call input unit 13 are the first and third bits. Only the bit is 1 and the other bits are 0. On the other hand, the transmission control CPU 12 specifies the second floor and the fourth floor from the input pattern.

Subsequently, the transmission control CPU 12
After temporarily saving the car call data (or the specified floor data) to the transmission control data 5, the data is transmitted to the transmission control CPU 21 of the main control device 20 at a predetermined cycle.

The transmission control CPU 21 receives the car call input data (or the specified floor data) at a predetermined cycle and writes it in the second RAM 22.

The main CPU 25 temporarily saves the data written in the second RAM 22 to the third RAM 24,
Referring to the specification data stored in the EEPROM 23,
The call registration data is written into the third RAM 24. Further, the main CPU 25 stores the call registration data in the second R
Transfer to AM22.

The second transmission control CPU 21 has a second RAM 2
2 is transmitted to the transmission control CPU 12 at a predetermined cycle.

The transmission control CPU 12 receives the call registration data at a predetermined cycle, writes it in the RAM 15, and turns on the corresponding car call button via the car call output unit 14. Thereby, it is clearly displayed that the call registration has been made by pressing the car call button.

When the car call button is turned on based on the call registration data, the correspondence of the corresponding bit pattern is used in the opposite direction. In other words, this case can be dealt with by shifting the bit pattern corresponding to the floor by 3 bits to the left.

Cancellation or cancellation of call registration is realized by the same data flow.

The processing program for creating the corresponding bit pattern stored in the storage unit 15 can be easily changed according to the specification data transmitted from the EEPROM 23 via the second transmission control CPU 21.

For example, FIG. 3C shows an example of a corresponding bit pattern in the case of a specification having one hollow floor. In this case, the car call button a2 corresponds to the first floor, the car call button b2 corresponds to the second floor, the car call button b3 corresponds to the hollow floor, the car call button b3 corresponds to the third floor, and the car call Button a4 corresponds to the fourth floor, and car call button b4 is 5
Corresponds to the floor.

As shown in FIG. 4, the corresponding bit pattern in this case is to right-justify the input bit pattern by ignoring the bits corresponding to the middle floor and shift the bit pattern to the right by 3 bits (insertion is Required left 3 bits (5
The 7th bit) is obtained by inserting 0). In other words, the processing program in this case is “right-justified the input bit pattern ignoring the bits corresponding to the middle floor,
Shift the bit pattern to the right by 3 bits (insert 0 for the left 3 bits (5th to 7th bits) that need to be inserted) "
Is described.

Also in this case, when the car call button is turned on based on the call registration data, the correspondence of the corresponding bit pattern is used in the opposite direction. That is, it can be dealt with by shifting the bit pattern corresponding to the floor by 3 bits to the left and shifting bits higher than the bit corresponding to the hollow floor to the left.

The change of the corresponding bit pattern stored in the storage unit 15 can be performed by the input device 27.

For example, a setting program which assigns the car call buttons to the floors by associating the car call buttons sequentially pressed in the floor setting mode with the floor order as it is, is called E.
If the program is stored in the PROM 26, when the setting program is operated, the mode is switched to the floor setting mode via the input device 27, and only by pressing the car call button in order, a processing program for creating the corresponding bit pattern is extremely easily. Can be changed.

As a switch for switching to the floor setting mode, a special switch may be provided, or other buttons may be used. For example, the floor setting is performed by simultaneously pressing the door open button and the door close button. The mode may be switched.

However, if a mode in which the mode can be switched to the floor setting mode too easily is adopted, there is a risk of being tampered. Therefore, the switching input to the floor setting mode is performed only when the elevator device is set, for example. Preferably it is possible.

As described above, according to the present embodiment, the correspondence (processing program) between the car call buttons a1 to a4 and b1 to b4 and the floor is stored in the RAM 15, and the car call input unit 13 receives the input. Is determined by the transmission control CPU 12 corresponding to the car call button for which
By changing the correspondence between the car call button and the floor stored in the AM 15, it is possible to easily cope with the change in the assignment of the car call button.

According to the present embodiment, the EPROM
By operating the setting program stored in the input device 27 by the input device 27, it is possible to easily cope with the change in the assignment of the car call button.

[0062]

As described above, according to the present invention,
The correspondence between the car call button and the floor is stored in the storage unit, and the floor corresponding to the car call button for which the car call input detection unit has detected the input is specified by the discrimination unit, and thus is stored in the storage unit. By changing the correspondence between the car call button and the floor, it is possible to easily cope with the change in the assignment of the car call button without requiring any work such as a design change and a wiring change.
