One monitoring terminal is installed in monitoring range, on each high pressure shaft tower.Weather ginseng near Timing measurement shaft tower
Number combines the timing acquiring condition of backstage setting according to the climatic information acquired, and when specific weather condition meets, startup is let out
The acquisition of leakage current, spread voltage and image.Each terminal is fitted with a burglar alarm, stolen when there is shaft tower tower material
When phenomenon, burglar alarm sends a signal to terminal, and terminal starts camera and takes pictures.Monitor terminal and background monitoring center
Between can be carried out data transmission by GSM/GPRS both of which, terminal can be to backstage upload gathered data, from the background can be with
Data, modification configuration etc. are inquired in time to terminal.Meanwhile by GSM network, monitoring personnel can also be by handset dialing and short
Message mode sends order, modification configuration and inquiry data etc. to terminal.Background monitoring central host is connect with database, immediately
Various data are stored, monitoring software uses expert system, the various data that network analysis acquisition comes to show number by General Purpose Interface
According to, while according to the data obtained, various charts are drawn, judge the subcase that insulate, and when reaching dangerous values in time to monitor
Member's early warning by way of short message.Meanwhile expert analyzing system also matches with the general-purpose interface of electric system, can facilitate
Realize data in the power system shared in ground.
As shown in Fig. 2, the external SIM card of G24 needs of work, host scm G24 communications are by sending AT to UART buses
It orders to realize.ON_N controls the switch of G24；RI_N is ring indication signal, when data communications equipment receives telephone exchange
When the bell signal of equipment, notification data terminal device（F040）Data communications equipment（G24）Receive artificial calling；And WKUPI_
N controls G24 enters or exits suspend mode；RTS is request to send signal, and CTS is to allow to send signal, when data communication is set
After receiving the RTS signals that data terminal equipment is sent, then first starts sending function, then send out CTS to data terminal equipment
Signal allows data terminal equipment to start transmission data；DTR is that data terminal equipment gets out signal, and DSR is that data communication is set
