Be provided with command center system, the signal of the control point that receiver receives flows to switch and computer by distributor, and computer transmits signal to higher level command centre by management information system (MIS Management Information System).
Advantageous effect of the present invention is as follows:
1, technological precedence: adopt up-to-date transmission technology COFDM (coding, quadrature, frequency division, multiplexing) modulation technique, realize the middle transmission of moving of monitored some video-audio signal, overcome video-audio signal have can't high-quality transmission in blocking and moving problem, signal quality has reached broadcast level SD standard, be particularly suitable for the needs of on-the-spot emergency first-aid repair, handle significant accident.
2, economical and practical: as to adopt optimized design to reduce cost.
3, easy to use: it is in use convenient especially to adopt advanced control technology to make.
4, safeguard facility: adopt the modularized design maintenance convenient.
5, powerful: advanced design concept makes systemic-function powerful, can give full play to systemic effect (video transmission, audio transmission, television relay etc.).
6, expansion is strong: system design has taken into full account the needs of upgrading in the future, has very strong upgrade function (two-way video, bi-directional data etc.).
In addition, advanced person's of the present invention technology, advanced design concept, powerful function of use have excellent popularization and are worth, many cover systems unite use just can form the wireless mobile transmission network of the whole province safety in production, the accident of electric power are handled significant, to ensure supply of electric power, safeguarding national security to stablize has irreplaceable important function.Enlarged the signal cover of communication van greatly, further improved communication van function, well solved the signal transmission issues of complex environment.
