The invention discloses an electric power system information acquisition wireless alarm method based on image recognition, and belongs to the field of power system alarm methods. A monitoring terminaland a monitored terminal are included. The monitoring terminal is provided with communication equipment, the monitored terminal is provided with a display device, a processing device and a monitoringdevice. The monitoring device is used for shooting telemetry data displayed by the display equipment, then the processing device is used for processing shot pictures to enable the shot pictures to befinally converted into binary images, and the processing device judges whether to send an alarm signal to the communication equipment of the monitoring terminal or not according to the size of an area occupied by the abnormal telemetry data in the binary images. The alarm method provided by the invention has the advantages of simplicity in operation, quickness in analysis and the like; once telemetry data is abnormal, the monitoring terminal can be notified in time, the purpose of wireless alarm is achieved, the alarm accuracy can be effectively improved, the labor cost can be saved, and themethod is an intelligent, efficient and environment-friendly novel information collection wireless alarm method.
