Abstract
The utility model relates to a power adjusting system for bidirectional broadcast transmission. The power adjusting system comprises a radio frequency circuit, a wireless chip, a data processing CPU (Central Processing Unit) and a signal control module, wherein the radio frequency circuit, the wireless chip, the data processing CPU and the signal control module are electrically connected in sequence and used for transmitting signals; an input/output module is arranged on the data processing CPU; and the signal control module is electrically connected with the wireless chip. According to the power adjusting system for the bidirectional broadcast transmission, disclosed by the utility model, the bandwidth distribution and the power control are organically combined, the uplink bandwidth is properly reduced at a cover edge, the transmission rate of the system is reduced, and the signal power spectrum density is increased, so that the farther transmission distance is obtained.
Description
[technical field]
The utility model relates to a kind of power regulating system, is specifically related to a kind of broadcasting transmitted in both directions power regulating system.
[background technology]
Traditional broadcast television technique is being combined with broadband technology; When realizing two-wayization of radio and television; The high-power covering that how to guarantee radio and television covers the consistent of maintenance coverage with the small-power honeycomb of broadband technology, is a pendulum significant problem that needs to be resolved hurrily in the field of business.
For solving the problems of the technologies described above, necessary a kind of structure improved broadcasting transmitted in both directions power regulating system that has is provided, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of the utility model is to provide a kind of and can allocated bandwidth and power control be organically combined, and effectively improves the broadcasting transmitted in both directions power regulating system of signal transmission distance.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of broadcasting transmitted in both directions power regulating system, and it comprises radio circuit, wireless chip, data processing CPU and signal controlling module; Wherein, said radio circuit, wireless chip, data processing CPU and signal controlling module electrically connect and transmit signal successively; Said data processing CPU is provided with an input/output module; Said signal controlling module and wireless chip electrically connect.
The broadcasting transmitted in both directions power regulating system of the utility model further is set to: in said data processing CPU also and be connected to SDRAM, flash memory, VPN chip and USB chip.
Compared with prior art; The utlity model has following beneficial effect: the broadcasting transmitted in both directions power regulating system of the utility model can organically combine allocated bandwidth and power control; Covering the edge, suitably reduce upstream bandwidth, reduce system transmissions speed; Improve the signal power spectrum density, reach farther transmission range.
[description of drawings]
Fig. 1 is the schematic diagram of the broadcasting transmitted in both directions power regulating system of the utility model.
[embodiment]
See also shown in the Figure of description 1, the utility model is a kind of broadcasting transmitted in both directions power regulating system, and it is made up of elements such as radio circuit 1, wireless chip 2, data processing CPU3 and signal controlling modules 4.
Wherein, said radio circuit 1, wireless chip 2, data processing CPU3 and signal controlling module 4 electrically connect and transmit signal successively.Said data processing CPU3 is provided with an input/output module 31.Said signal controlling module 4 electrically connects with wireless chip 2.
Further; In said data processing CPU3 also and be connected to SDRAM32 (Synchronous Dynamic Random Access Memory, synchronous DRAM), flash memory 33; VPN (Virrual Private Network, VPN) chip 34 and USB chip 35.
The operation principle of the broadcasting transmitted in both directions power regulating system of the utility model is following: when broadcast singal carries out long-distance transmissions; Suitably reduce upstream bandwidth distribution through data processing CPU3 and signal controlling module 4; And feed back to wireless chip 2 through signal controlling module 4, and make it improve the signal power spectrum density, increased covering; And remaining effective binding of broadcast system and bilateral system, error rate of system is in minimum state all the time.Otherwise when finding that uplink signal strength is higher than set point, when promptly carrying out short-distance transmission, maximum bandwidth is recovered at the terminal gradually.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
