Abstract

The invention discloses a low-carbon environment-friendly China mobile multimedia broadcasting (CMMB) signal monitoring device. The device comprises a control module, and a storage module, a CMMB signal acquisition module and a wireless communication module which are connected with the control module, and further comprises a power management module, a power conversion module, a battery module and a solar module, wherein the power conversion module and the battery module are connected with the power management module; and the solar module is connected with the power conversion module. The device is low-carbon and environment-friendly due to the adoption of solar power supply and advanced power management, and can be arranged at an intensive monitoring position in a distributed way and run in an unattended way free from the influence of a geographical environment to greatly save man power and overcome the shortcoming that a mounting position is restricted by power supply conditions in a conventional mounting mode.

Description

technical field [0001] The invention relates to a low-carbon and environment-friendly CMMB signal monitoring device, which belongs to the field of wireless signal testing. Background technique [0002] China Mobile Multimedia Broadcasting (CMMB for short) is a set of mobile TV and multimedia standards currently used in my country. It is formulated and promoted by the State Administration of Radio, Film and Television. It is based on the satellite and Ground Interactive Multi-Service Architecture (STiMi). [0003] CMMB's satellite signal uses S-band 2.635-2.660GHz for coverage, urban ground signal uses U-band 470-798MHz for coverage, and provides 25 sets of video, 30 sets of audio programs and additional data channels with a bandwidth of 25MHz. In order to better provide multimedia broadcasting services, a series of tests are required during the construction and operation of CMMB, such as measuring signal coverage and signal strength, and making improvements based on the test...
