The invention relates to an auxiliary monitoring system for electricity transformation and distribution safety production and a monitoring method of the auxiliary monitoring system for electricity transformation and distribution safety production. The auxiliary monitoring system comprises a station terminal device and a concentrated monitoring center; the station terminal device comprises an Internet of Things intelligent host, a video server, an IPCAM and various sensing devices like a transformer core temperature controller, a winding temperature controller, an electricity distribution module, a fire control device, a security and protection control device, a temperature and humidity control device, an air-conditioner control device, a dehumidifier control device, a heater control device and other intelligent control devices. The concentrated monitoring center comprises a management server, a data communication server, an alarm processing server, an authentication server, a streaming media live telecast server, a streaming media demand server and a PC client terminal. By means of the system and the method, intelligentization of the monitoring system is achieved, and early warning and alarming of safety production in an electricity transformation and distribution site are achieved. By means of the auxiliary monitoring system, existing walkaround inspection is changed into automatic monitoring, and the scattered walkaround inspection is changed into concentrated monitoring, so that the labor cost is reduced, the labor intensity of an operator on duty is greatly reduced, and the social benefits of energy saving, emission reduction, staff downsizing and efficiency improving are achieved.
