which respectively control input/output of car cabin position indicators (not shown) for displaying floors where the car cabin of the elevator is presently running, hall buttons (not shown) for calling the elevator installed at the respective halls, and the like, and which respectively have intrinsic numbers (identity numbers), a communication relay (communication device)
102
for relaying communication among the plurality of respective cabin controllers
103

103
N, the group management controller
104
, and the plurality of landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
, and a network
101
as a communication line for realizing transmission and reception of information among the plurality of respective cabin controllers
103
A to
103
N, the group management controller

, the plurality of landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
, and the communication relay
102
.
The communication relay
102
used as a communication device for the known elevator control system is constructed by a plurality of slave communication portions
108
A to
108
N which are connected to hall transmission lines
110
A to
110
N as common transmission lines provided for every hall button series divided according to the installation number of the landing floor terminals (hall controllers)
105
a

105
k
,
106
a
to
106
k
and realizes communication with the landing floor terminals (hall controllers)
105
a
to
105
k
and
106
a
to
106
k
, a master communication portion
107
for transmitting and receiving information to/from the plurality of respective cabin controllers
103
A to
103
N, and an internal network
109
for connecting the master communication portion
107
and the plurality of slave communication portions
108
A to
108
N.
Hereinafter, the operation of the communication device for the known elevator control system constructed in this way will be described. First, the master communication portion
107
receives information to be transmitted from the respective cabin controllers
103
A to
103
N and the group management controller
104
through the network
101
to the side of the landing floor terminals (hall controllers), classifies the transmitted information by the floor and the hall transmission line, and outputs them through the internal network
109
to the slave communication portions
108
A to
108
N. On the other hand, information received from the slave communication portions
108
A to
108
N through the internal network
109
is classified by the master communication portion
107
by the floor and the hall transmission line, and then, it is transmitted to the respective cabin controllers
103
A to
103
N and the group management controller
104
.
Next, the slave communication portions
108
A to
108
N transmit data, which are received from the master communication portion
107
through the internal network
109
, to the hall transmission lines
110
A to
110
N to which they are respectively connected. On the other hand, the slave communication portions
108
A to
108
N transmit information, which is received from the landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
through the hall transmission lines
110
A to
110
N, to the master communication portion
107
through the internal network
109
.
The communication relay
102
receives input information from the landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
through the hall transmission lines
110
A to
110
N, adds information to enable identification of the hall transmission line to which the landing floor terminal (hall controller) as a sender of the received information belongs, and the floor on which the landing floor terminal (hall controller) is installed, and transmits it through the network
101
. Hereinafter, this operation will be described in detail.
The plurality of landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
have respectively intrinsic numbers on the floors. According to a first method, an address map is set in an internal memory of the master communication portion
107
, and data indicating which of the hall transmission lines
110
A to
110
N is controlled by the respective slave communication portions
108
A to
108
N, are previously stored in the respective addresses of the address map. At this time, a format of the data stored in one of the respective addresses is constituted by an intrinsic number of one of the landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
corresponding to the respective floors, and an intrinsic number corresponding to one of the respective hall transmission lines
110
A to
110
N.
In such a state, when the landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
output arbitrary information, together with their own intrinsic numbers, to the hall transmission lines
110
A to
110
N, the respective slave communication portions
108
A to
108
N transmit the information through the internal network
109
to the master communication portion
107
. The master communication portion
107
compares the intrinsic number included in the inputted information with the data of the address map stored in it, and can judge that the inputted information is from which hall controller of which hall transmission line, and therefore, it is possible to add these pieces of information to the received data and transmit them to the network
101
.
Next, according to a second method, data of an address map set in the master communication portion
107
are outputted to the plurality of slave communication portions
108
A to
108
N. When each of the slave communication portions
108
A to
108
N receives arbitrary information, together with an intrinsic number, transmitted from the landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
through the hall transmission lines
110
A to
110
N, it compares the intrinsic number contained in the received data with the data of the address map, adds an intrinsic number of the hall transmission line which is controlled by the slave communication portion itself, and transmits them to the master communication portion
107
. In this case, by directly transmitting the data received from the slave communication portions
108
A to
108
N to the network
101
, the master communication portion
107
can transmit the data containing the information of the transmission lines and the floors to which the landing floor terminals (hall controllers)
105
a
to
105
k
, and
106
a
to
106
k
belong, and the information of the floor.
Although the known communication device is constructed as described above, the foregoing method for identifying the hall transmission line and floor to which the landing floor terminal (hall controller) belongs, which is realized by such a known communication device, has problems as follows:
That is, first, in the elevator control system, the hall button connected to each of the hall controllers
105
a
to
105
k
, and
106
a
to
106
k
is made to hav
