The invention discloses a cable operation information monitoring system and an implement method thereof. The cable operation information monitoring system comprises an information sensor assembly, an information collecting terminal, a data managing repeater, a monitoring center and a field detection terminal; the information collecting terminal is composed of a voltage signal collecting circuit, a current signal collecting circuit, an analogue switch, a first advanced RISC machine (ARM) processor and a first wireless transmitting and receiving module; an output end of the analogue switch is connected with a corresponding input end of the first ARM processor; the data managing repeater is composed of a global positioning system (GPS) timing module, a first general packet radio service (GPRS) module and a second ARM module; and the monitoring center comprises a web server, a database server and a second GPRS module. By means of the cable operation information monitoring system, information of cable temperatures, current, electric field changes and the like is effectively evaluated and diagnosed, data records are periodically collected in 24 hours, and power distribution reliability is greatly improved by means of condition based maintenance.
