Monitoring network system is made of terminal device (line loss registering instrument), networking facility and host computer (monitoring center) three parts.
Be installed on each transformer secondary loop, district (or other monitoring point) and carry out on-site data gathering and analyzing and processing.Distribution intelligence line loss registering instrument is formed management system for monitoring as field device by certain transmission mode and center cluster; When the field monitoring instrument is not networked, also can be used as independent data processing and use.
Monitoring parameter comprises: line loss electric weight, k-factor, voltage (electric current), power, frequency, power factor etc.Can show at the scene, store, also can be provided with and freeze day detected parameters such as line loss to be stored.
Can report to the police according to being provided with initiatively for voltage, electric current, transfiniting of power.
According to different networking modes, adopt corresponding networking facility, general GPRS terminal is mainly communicated by letter by following several modes to connecting between the server:
1, server adopts fixedly IP of public network, and the GPRS terminal is connected by commmunication company's public network route foundation and server.This mode networking is fairly simple, and cost is lower, is convenient to upgrade maintenance.
2, server and GPRS terminal adopt the networking of VPN private network mode
This mode networking needs the customization GPRS of commmunication company terminal SIM card, divides private ip address, and server address directly inserts the VPN private network.Server is directly incorporated GPRS network into like this, and other public network IP can't insert VPN, and server is safer like this, and it is faster to communicate by letter.This mode advantage: network is safer, and it is faster to communicate by letter, but cost is higher.Shortcoming: networking is cumbersome, needs commmunication company to cooperate inconvenient remote maintenance.
