Abstract

A communication system is provided. The communication system includes slave modules outputting collected data to a master module, and outputting data priority processing request information to the master module; and the master module connected to slave modules, collecting data from the slave modules, and processing, by priority, data from a corresponding slave module based on the data priority processing request information received from at least one slave module.

First claim

What is claimed is:

1 . A communication system comprising:
slave modules outputting a response signal corresponding to a request signal received from a master module, and outputting a data priority processing request message to the master module; and the master module connected to slave modules, collecting data from the slave modules, and processing, by priority, data from a corresponding slave module based on the data priority processing request message received from at least one slave module.

2 . The communication system according to claim 1 , wherein the master module comprises:
a first communication unit transmitting a data request signal to the slave modules and receiving a response signal corresponding to the request signal; and a second communication unit connected to a second serial bus that receives the data priority processing request message from the slave modules and collects corresponding data.

3 . The communication system according to claim 2 , wherein the slave module comprises:
a first communication unit connecting to a first serial bus that outputs data to the master module according to a preset sequence; and a second communication unit connected to a second serial bus that outputs information for a data priority processing request and corresponding data among pieces of received data.

4 . The communication system according to claim 2 , wherein the master module collects data sequentially from a slave module nearest to the master module through the first communication unit.

5 . The communication system according to claim 2 , wherein the master module further comprises a communication drive according to a signal output through the first communication unit.

6 . The communication system according to claim 5 , wherein the first communication unit outputs a transistor transistor logic (TTL).

7 . The communication system according to claim 1 , wherein in a case where the slave module transmitting the data priority processing request message among the slave modules is in plurality, the master module collects and processes corresponding data according to priorities set for corresponding slave modules.

8 . The communication system according to claim 7 , wherein a slave module nearest to the master module has a top priority.

9 . The communication system according to claim 7 , wherein the priority is preset by the master module or is based on information on data to be collected from the slave module.

10 . The communication system according to claim 1 , further comprising switch units that correspond to the slave modules,
wherein the switch units are disposed between the slave modules and the master module.

11 . The communication system according to claim 10 , wherein the switch unit comprises:
a first buffer drive setting a path for outputting a priority processing request message from a slave module corresponding to the switch unit; and a second buffer drive setting a path for outputting, to the master module, a priority processing request message from a slave module that does not correspond to the switch unit.

12 . The communication system according to claim 11 , wherein the first buffer drive and the second buffer drive alternately operate.

13 . The communication system according to claim 12 , wherein the second buffer drive is enabled and the first buffer drive is disabled when the master module performs the sequential data collection mode on the slave module.

14 . The communication system according to claim 12 , wherein the second buffer drive transmits a data priority processing request message to the master module and shifts to a disable state, when in an enable state, a data priority processing request is sensed from the slave module.

15 . The communication system according to claim 14 , wherein the first buffer drive shifts from the disable state to the enable state to output the priority processing request data when the second buffer drive shifts to the disable state.

16 . A communication system comprising:
a slave module outputting a response signal for a request signal received from a master module, transmitting a data priority processing request message to the master module, and outputting data to the master module according to a preset priority; and a switch unit connecting the master module and slave modules and setting a data output path according to the data priority processing request.

17 . The communication system according to claim 16 , wherein the switch unit comprises:
a first buffer drive setting a path for outputting a priority processing request message from a slave module corresponding to the switch unit; and a second buffer drive setting a path for outputting, to the master module, a priority processing request message from a slave module that does not correspond to the switch unit, wherein the first buffer drive and the second buffer drive alternately operate.
