Method for realizing transmission and coverage of security monitoring information in user resident region

Abstract

The invention discloses a method for realizing transmission and coverage of security monitoring information in a user resident region. The method comprises the following steps that: in a downlink direction, after a security monitoring data signal is converted into a radio frequency signal via modulation and upper conversion, the radio frequency signal is combined with other service downlink radio frequency signals to form an electric signal, the electric signal is shunted and transmitted after the electric signal is converted into an optical signal; the optical signal is converted into the electric signal, and is shunted and transmitted to an inferior transmission unit or a user service interface unit after the electric signal is subjected to compensated amplification; the optical signal is converted to the electric signal once again, the electric signal is outputted after filtering and amplifying, and is transmitted to an antenna through a feeder line and radiated to user mobile phones in various mobile networks in the corresponding coverage region, wherein the security monitoring radio frequency signal is transmitted to corresponding PDA and PC user terminals by utilizing the 'Bluetooth' technology and the internet. Signal processing in the uplink direction is opposite to that in the downlink direction. The method provides a scheme for accessing various network signals including the security monitoring information for users in the resident region, and completes access, load transmission and coverage distribution functions to various user information service in the resident region.

Description

technical field The invention relates to the technical field of communication, in particular to a technical method for realizing security monitoring information transmission and signal coverage in a user premises area access network. Background technique There are a large number of security monitoring information transmission and signal coverage distribution requirements in all user resident areas. For example, various safety monitoring information such as fire prevention, anti-theft, personal safety (distress, sudden illness, etc.), traffic safety, etc. in residential quarters need real-time transmission and seamless coverage. The safety monitoring information includes video monitoring information, smog warning information, gas (natural gas or coal gas) leakage concentration in the air, and the like. With the modernization of social public facilities and the rapid development of digital homes and personal digital assistants (PDAs), not only property management and communit...

AI Technical Summary

Problems solved by technology

However, many existing radio frequency service signal access methods in customer premises are not applicable due to different standards, or the narrow frequency band cannot implement multi-network integration, and it is impossible to independently build a network that can implement multi-source access including security monitoring information Unified resident access network
