IoT-based integrated management type switchgear system according to the invention can in general, switchgear (high voltage switchgear, a low-pressure distribution panel), switchgear, distribution boards, power status information, device state information of the power distribution devices, such as the MCC (Motor Control) is integrally detected the power over the unit over the integrated simply and smoothly to the monitoring / management as being vulnerable environment condition information transmission and reception is to be by the BLE communication (low accessibility, etc.) open field in the administrator or the gate of the power distribution device in which the to that site administrators power status information of the power distribution device, the device state information may be quickly and easily transmitted to the Bluetooth communication, the power of the power distribution device state information, monitoring information, and device error monitoring information such as the scene information output from the field equipment and remote terminals or mobile site administrator text / voice messages via the handset, text / sound information for alerts And quickly and seamlessly outputted in various forms, such as, in particular, the three-axis acceleration power distribution detected by the sensor device movement information device such as a bolt determining whether information extracting the important points from the shake feature information derived by the FFT frequency analysis of the state determination and the information is being subject to grasp the shake and the device more / damage accordingly be accurately and precisely generated by earthquakes calculated, accident and through which the field manager to quickly identify the source of the device more / damage can respond It has a technical feature which can minimize the occurrence.
