Description

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 sections.

[0002]

2. Description of the Related Art In recent years, electronics in vehicles have been promoted. Along with the progress of these electronics, the number of connecting wires, that is, wire harnesses, between a plurality of terminal devices and each operation unit for operating them increases, and the increase in the wire harness increases the overall weight. There was a problem that the reliability of the device was lowered.

Therefore, in recent years, various so-called multiplex communication systems have been developed which are capable of transmitting information relating to the operation of a large number of operating sections through a small number of connecting lines.

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 operating side slave station J1 to which a plurality of operating sections are connected are provided.
, Jn, and a plurality of these slave stations and a central side master station SS are connected by 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. 10, the master station S
S is composed of a communication control device 101 and a control device 103. The slave station J1 is connected with a plurality of switches SW1, SW2, SW3, SW4, and SW5, and information regarding these switch operations is input to the communication control device 107 via the input interface 105. It

When the slave station J1 is designated by polling from the master station SS as shown in FIG.
Switches SW1 and S1 connected to themselves in response to the instruction of S
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 the logical value "1" and transmitted.

Similarly, when the slave stations J2, J3, ... Are designated by polling from the master station SS, each designated slave station is connected to itself immediately after that in response to the instruction from the master station SS. Information on the operation unit such as a switch is transmitted.

[0008]

By the way, when 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.

However, the information of the operation section transmitted by each slave station is only the information indicating the operating state of whether the switch is in the on state or the off state. For example,
In the slave station J1, the switches SW1, SW2, SW3, SW4 and SW5 operated between the time designated by the previous polling and the time designated by the current polling.
Information indicating the on or off state of the switch SW
It was only transmitted in the order of 1, SW2, SW3, SW4, SW5. Therefore, in the master station SS, the switches SW1,
Whether SW2, SW3, SW4 and 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, when it is attempted to determine the order in which a plurality of switches are operated, the switches are operated at intervals longer than the polling cycle from the master station, or
It is necessary to perform polling at a communication speed higher than the expected switch operation speed, that is, at a cycle shorter than the switch operation speed.
