Embodiment 1
[0140] According to the designed station data, geographic data, antenna data and other information, the present invention adopts a suitable propagation prediction model to predict the coverage field strength of the radio and television coverage network, and provides it to users for reference in a graphical manner, and the prediction results The basis for network analysis. According to the distribution of field strength, the functions of interference between each transmission point, overall coverage statistics, and reasonable frequency selection are completed. The test data of the overlay network can be used to correct the parameters of the propagation prediction model, use the optimized model to analyze the network optimization of the entire network, and finally complete the planning of the entire overlay network.
[0141] see figure 1 , image 3 , the present invention discloses a radio and television coverage network planning system, the system includes a database subsyste...

The invention discloses a system for planning coverage networks of broadcasting and television. The system comprises a database subsystem, a network design subsystem and a network optimization subsystem, wherein the database subsystem comprises a geographical information database, a station database, an antenna database and a drive test information database; the network design subsystem comprisesa coverage analysis module, an interference analysis module, a frequency analysis module and a network analysis module; and the network optimization subsystem comprises a station geographic position optimization module, a transmitting power optimization module and an antenna automatic forming module. The system and the method for planning coverage networks of broadcasting and television have the functions of automatic addressing, automatic optimization of transmitting power and automatic forming of antenna parameters, and can realize reduction of construction cost and energy consumption underthe premise of meeting network coverage requirements.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a planning system, in particular to a broadcasting and television coverage network planning system; at the same time, the invention also relates to a method for realizing the above-mentioned planning system. Background technique [0002] At present, domestic and foreign radio and television are gradually transforming from analog technology to digital technology, and the radio and television coverage network is also transitioning from the original analog transmission network to the digital transmission network. requirements, and better provide radio and television programs for the broad masses of the people. [0003] In large and medium-sized cities, due to the high density of buildings, higher requirements are put forward for the network of radio and television coverage networks. A single high-power transmission point of a high tower will cause coverage one by one du...
