The invention discloses a system and a method for intelligently protecting a metering box. The system comprises a metering box intelligent monitoring module and a remote control master station. The metering box intelligent monitoring module is used for monitoring the running state data of a metering box, determining an abnormal event, encrypting the abnormal event and reporting the abnormal eventto the remote control master station. The metering box intelligent monitoring module comprises an electronic lock control unit, a camera acquisition unit, an RFID radio frequency tag reading unit, a DC magnetic field monitoring unit, a high-frequency magnetic field monitoring unit, a temperature and humidity monitoring unit, an incoming line current measuring unit, a security key control unit anda CPU control unit. The remote control master station is used for issuing a control command through the backstage or a mobile terminal to perform safety control on the metering box. Running state dataonline monitoring, remote control and abnormal event reporting in the running link of the metering box are realized in an all-round manner. Intelligent power use is fully supported. The risk of electricity stealing is reduced. The abnormal loss of lines is greatly reduced. The damage to field operation equipment is reduced.
