Abstract

A noise detection device includes a connector used for connecting a multicore cable, a connector used for connecting the communication device, a noise-detecting data generation unit which generates noise-detecting data with an error detection sign to detect the noise, and a detection unit which continuously transmits or receives the noise-detecting data using at least one core line not used in the communication among core lines of the multicore cable to detect an error.

Claims

1. A noise detection device connected between an end of a multicore cable and a communication device to detect a noise generated when a communication is performed between the communication devices, comprising:

a connector used for connecting the multicore cable;

a connector used for connecting the communication device;

a noise-detecting data generation unit generating noise-detecting data to detect the noise;

a data transmitting/receiving unit continuously transmitting or receiving the noise-detecting data using at least one core line not used in the communication among core lines of the multicore cable;

a detection unit checking the received noise-detecting data to detect an error; and

an optical connector connecting an optical cable to perform data communication,

wherein the data transmitting/receiving unit includes a plurality of switchable transmission clocks, and

wherein the data transmitting/receiving unit includes a plurality of switchable drivers/receivers.

2. The noise detection device according to claim 1, further comprising:

a switch unit switching a communication line in the multicore cable to transmit or receive the noise-detecting data.

3. The noise detection device according to claim 2, further comprising:

a display unit displaying an error when the error is detected by the detection unit.

4. The noise detection device according to claim 2, further comprising:

a wireless transmission unit transmitting information of an error detected by the detection unit together with an ID uniquely assigned to the noise detection device.

5. The noise detection device according to claim 1, further comprising:

a display unit displaying an error when the error is detected by the detection unit.

6. The noise detection device according to claim 5, further comprising:

a wireless transmission unit transmitting information of an error detected by the detection unit together with an ID uniquely assigned to the noise detection device.

7. The noise detection device according to claim 1, further comprising:

a wireless transmission unit transmitting information of an error detected by the detection unit together with an ID uniquely assigned to the noise detection device.

8. A noise detection system comprising:

the noise detection device according to claim 7; and

a monitor device,

wherein the monitor device includes

a wireless reception unit used to receive the error information from the wireless transmission unit of at least one or more noise detection devices, and

a display unit displaying the error information for each ID.
