DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device, and more particularly to a communication device capable of transmitting information related to the operation order of a plurality of operation units.

[0002]

2. Description of the Related Art In recent years, electronics in vehicles have been promoted. With the development of these electronic devices, connection lines between a plurality of terminal devices and respective operation units for operating the terminal devices, that is, wire harnesses are increased, and the total weight is increased due to the increase of the wire harnesses. There has been a problem that the reliability of the device is reduced.

[0003] In recent years, various so-called multiplex communication systems capable of transmitting information relating to the operation of a large number of operation units through a small number of connection lines have been developed.

In the conventional multiplex communication system shown in FIG. 10, a terminal-side slave station (not shown) to which a plurality of terminal devices are connected and an operation-side slave station J1 to which a plurality of operation units are connected.
Jn, J3,..., Jn, and the plurality of slave stations are connected to the central master station SS via a common communication line LL. A desired terminal device is driven by performing multiplex communication between these slave stations and the master station SS.

For example, in the conventional example shown in FIG.
S is composed of a communication control device 101 and a control device 103. Further, switches SW1, SW2, SW3, SW4, and SW5, which are a plurality of operation units, are connected to the slave station J1, and information related to these switch operations is input to the communication control device 107 via the input interface 105. You.

When the slave station J1 is designated by polling from the master station SS as shown in FIG.
Switches SW1 and S connected to itself according to the instruction of S
The information of W2, SW3, SW4, and SW5 is transmitted. For example, when the switches SW1, SW2, and SW5 are turned on, as shown in FIG.
2, only the first, second, and fifth bits corresponding to SW5 are set to logical value "1" and transmitted.

Similarly, when the slave stations J2, J3,... Are designated by polling from the master station SS, each of the designated slave stations is immediately connected to itself according to the instruction of the master station SS. The information of the operation unit such as a switch is transmitted.

[0008]

When, for example, a plurality of push button switches of a telephone are connected as the operation unit connected to the slave station, it is necessary to grasp the operation order of each push button switch.

[0009] However, the information of the operation unit transmitted from each slave station is only information indicating the operation state of whether the switch is on or off. For example,
In the slave station J1, the switches SW1, SW2, SW3, SW4, and SW5 operated between the time specified by the previous polling and the time specified by the current polling.
Information indicating the ON or OFF state of the switch SW
1, only SW2, SW3, SW4, and SW5 were transmitted in that order. Therefore, in the master station SS, the switches SW1,
Whether SW2, SW3, SW4, SW5 are on,
Although it is possible to determine whether the switch is in the off state, it is not possible to determine the order in which the plurality of switches SW1, SW2, SW3, SW4, and SW5 are operated.

Therefore, in order to determine the order in which a plurality of switches have been operated, the switches must be operated at intervals longer than the polling cycle from the master station, or
Polling must be performed at a communication speed higher than the expected switch operation speed, that is, at a cycle shorter than the switch operation speed.
