Emergency base station and method for realizing emergency communication

Abstract

The embodiment of the invention relates to an emergency base station and a method for realizing the emergency communication. The emergency base station comprises an analog processing front end, a D / A-A / D conversion module, an interface programmable logic array FPGA, a base-band processing module, a protocol control processing module, an E1-Ethnet conversion module, a power supply and a clock module. The application of the emergency base station and the method can provide a high emergency communication bandwidth in complex environment, reduce the power consumption and prolong the working time effectively.

Description

technical field [0001] The invention relates to the technical field of wireless communication equipment, in particular to a low-power broadband emergency base station equipment and a method for realizing emergency communication that can be used flexibly in complex environments. Background technique [0002] With the development of wireless communication technology, the dependence of the government and citizens on communication will become more obvious, especially in the event of emergencies and disasters, it is more necessary to use various communication means to report danger, command rescue and implement emergency assistance, etc. And a rapid response, comprehensive and efficient mobile emergency communication equipment that can be applied to military, anti-terrorism, security, water conservancy, land resources, forest fire prevention, public emergencies, environmental monitoring and other occasions will ultimately reduce the loss of the country and the people, maintain S...

Problems solved by technology

[0003] The wireless emergency communication equipment commonly used at present is mainly converted from traditional GSM (Global System for Mobile communications, Global Communications) or CDMA2000 (Code Division Multiple Access, Code Division Multiple Access) integrated base station, in which the schematic diagram of GSM is taken as an example like figure 1 Shown: However, based on the composition of this kind of emergency communication equipment, it is often narrowband-based, basically only supports voice or data services with small bandwidth, it is difficult to provide high bandwidth, and cannot meet the current requirements for broadband wireless emergency communication At the same time, at the emergency communication site, in addition to putting in new equipment for communication, it is also necessary to maximize the effectiveness of the existing public communication equipment

And as figure 1 As shown in the traditional emergency communication equipment, when the link between the GSM base station controller and the mobile switch fails, all the base stations served by the base station controller cannot work, so a large number of users cannot use the existing network; and, due to The spectrum situation at the emergency site is relatively complicated. Traditional wireless emergency communication equipment does not have the spectrum sensing function. The working frequency and the power of the transmitted signal are usually configured by the user. Therefore, the wireless network at the emergency site is troublesome.

[0004] At the same time, due to the high power consumption of traditional emergency base station equipment, it needs mains power or bulky power supply equipment to work at the emergency site, but the emergency site may not be able to provide mains power, and the communication equipment's own power supply or battery guarantees its communication work The time is also very limited, which puts forward better requirements for the power consumption of emergency base station equipment
