Operation environment monitoring device for relay protection device and monitoring method thereof

The invention discloses an operation environment monitoring device for a relay protection device. The operation environment monitoring device for the relay protection device comprises a monitoring terminals, the monitoring terminals are respectively connected with the relay protection device, a video collecting device and an on-line operation environment collecting device, and the on-line operation environment collecting device is connected with an air sensor, a temperature sensor, a humidity sensor and a vibration sensor. The air sensor, the temperature sensor, the humidity sensor and the vibration sensor are installed on a cabinet wall of the relay protection device, and full shielding design is adopted by the air sensor, the temperature sensor, the humidity sensor and the vibration sensor. According to the operation environment monitoring device for the relay protection device, real time data collected by the relay protection device is obtained, operation environment on-line monitoring information is received, and thereby the integrated monitoring device for the relay protection device is formed. When a relay protection device operation environment index is beyond a normal operation allowed range, the monitoring device alarms to avoid malfunctions of the relay protection device caused by environment factors, and the operation safety and reliability of the relay protection device are improved.
