The invention discloses a remote monitoring system for the loosening state of a fastening bolt of a power transmission line. The remote monitoring system comprises an intelligent nut, a ground receiving device, terminal equipment and handheld equipment. The intelligent nut is used for detecting whether the fastening bolt connection point is abnormally heated or not, temperature rise caused by abnormal heating is converted into electric energy to supply power to the intelligent nut, and the intelligent nut transmits a wireless alarm signal; the ground receiving device judges whether the temperature is abnormal or not according to the time interval of the adjacent early warning signals, so that the loosening state of the bolt is judged; the system forms a data transmission network by virtue of each ground receiving device, and bolt loosening data is transmitted to terminal equipment of a control room, so that early warning of abnormal heating of a fastening bolt connection point is realized; the handheld device
