Abstract

A communication system is provided. The communication system includes a plurality of remote terminal units (RTUs) outputting a state signal. The communication system includes a communication device receiving the output state signal from each of the plurality of RTUs and generating signal quality information, which is quality information on the received state signal. The communication system includes a control device obtaining the signal quality information and the state signal, determining at least one RTU among the plurality of RTUs as a load according to a preset condition in response to the obtained signal quality information, and generating system analysis information on the plurality of RTUs, which includes the at least one RTU determined as the load, on the basis of the state signal.

Claims

1. A communication system comprising:

a plurality of remote terminal units (RTUs) configured to output a state signal;

a communication device configured to receive the output state signal from each of the plurality of RTUs and generate signal quality information of the state signal, wherein the signal quality information represents whether the state signal is normal or erroneous; and

a control device configured to;

receive the state signal from the plurality of RTUs through the communication device,

receive the signal quality information from the communication device,

determine whether the signal quality information of the state signal received from the plurality of RTUs is erroneous signal information or normal signal information,

when it is determined that at least one RTU among the plurality of RTUs has a normal state signal based on the signal quality information, generate analysis information for the at least one RTU based on the normal state signal of the at least one RTU,

when it is determined that the signal quality information corresponding to a specific RTU among the plurality of RTUs is the erroneous signal information, determine the specific RTU as a resistor load so that values obtained from the at least one RTU are not affected, and generate analysis information for the specific RTU based on the state signal of the specific RTU, wherein the signal quality information corresponding to the specific RTU is received after receiving a state signal of the specific RTU, and

generate system analysis information for the plurality of RTUs based on the analysis information of the at least one RTU and the analysis information of the specific RTU by analyzing the specific RTU as the resistor load without using the state signal of the specific RTU,

wherein the control device controls each of the plurality of RTUs on a basis of the generated system analysis information.

2. An operating method of a communication system, the operating method comprising:
