Along with the development of mobile communication technique, mobile GPRS (General Package Radio Service) platform can realize IP connection anywhere and end to end wireless transparent transmission, so that it can provide convenient solution for electric power system existing long-distance connection of intelligent terminal with host station.
The county-level electric power network dispatch automation system is often upgraded with the developments of computer technology and electric power system automation. The upgrade project is primarily on the improvements of the host station end.
from the implementation, the software is composed of main-station communication module, PDA communication module, timing module, reading meter module, storing data module, frequently inspect module and remote update module.
The system may support any connection protocols that connect to the main-station system and other automated systems through the independent port processing course and the protocol processing program (dynamic library) which can be disposed.
A main station with a 100-m mast is situated at the NE urban/rural border.
In addition to the main station, the project comprises: measurements from two 14-m masts, one on the top of a centrally located building, the other mobile; pilot balloon ascents; tethered balloon soundings, car-borne temperature traverses etc.
A two-year study (1977/78 and 1978/79) was carried out using GT I seedlings raised in polybags at the Rubber Research Institute of Nigeria (RRIN) main station, to determine the response of rubber seedlings to the application of N, P, K fertilizer.
According to the system's specification, a battery must be used to provide adequate power to operate the main station.
Alternatively, the main station of Heidelberg is only 1 km away from the city centre and is connected with the most important European cities.
