I. Overview of weak network aggregation communication guarantee system Wireless aggregation communication system, based on a new generation of information technology, is a new technology that is specially used for multimedia data transmission and processing in video, audio, text, pictures and other formats. Through the aggregation of any signal captured on the scene to form a large and anti-jitter uplink and downlink channels, the network transmission protocol in the form of continuous media streams from the source to the destination, and after the destination receives, cached, according to the time of the network transmission Play in real time in order. Second, the system platform to achieve the program Weak network multi-link aggregation communication system Illustration: The core application of the system is to provide a stable communication environment in the case of weak networks, network jitter, and base station damage. It supports international standard mobile broadband network standards (such as 2G/3G/4G) and supports private networks 1.4G and 1.8. G-band, while supporting WIFI, cable, forming a large and anti-jitter uplink and downlink channels, with "high traffic volume, high stability, high security, high convenience, low cost" features. The program consists of seven parts: front-end coding system, front-end communication system, back-end aggregation system, streaming media system, acceleration system, central control system and viewing system. 1. Front-end coding system Front-end coding system can connect multiple sources, including HDMI source, sdi source, etc. Up to 60 frames per 4k can be transmitted. It can be connected to cameras, mobile phones, drones, surveillance cameras and other front-end devices. . 2. Front-end communication system The front-end communication system receives the data of the encoding system and completes the re-unpacking and link selection and transmission of the data. The load has a fast and reasonable load and is a core component for large-volume data transmission. 3. Backend polymerization system The system is responsible for sorting and aggregating the data of each physical link drive, restoring the front-end unpacking data back to the original data, and the system is also responsible for forward error correction. 4. Streaming media system This solution provides our own streaming media system, which has the characteristics of large access data and rapid processing. 5. Acceleration system For the data that has been transmitted to the server, if it needs to be allocated to multiple people, this solution also provides an acceleration system (mainly for streaming media), which can carry a higher level of access. 6, in the control system This program provides a sub-privilege control system, which can be used for multi-decentralized management of the raw data from the front-end drive, and better meets the relevant requirements of the emergency system for confidentiality. Third, the core module technology analysis The system is equipped with the first high-performance, high-value-added and network-free configuration in China -- the "Universal High-traffic Aggregation Communication Module": The modular device is a general-purpose platform product that can provide a network for communication equipment. Aggregated wireless links can also be used to aggregate wired links. They can aggregate private network frequency bands and aggregate public network frequency bands (communicated by the three public networks: Telecom, Mobile, and Unicom). The entire system has good compatibility. In areas where private networks have been deployed, private network transmission will be mainly selected, and public network links may be aggregated in areas not covered by the private network. Therefore, the communication module has good actual combat capabilities. 1, high traffic volume The demand for communications security is often caused by severe signal attenuation or densely populated places. The communication capability of a single link will drastically decline. Under such circumstances, relying on a single link to achieve rapid transmission of large volume of information becomes extremely difficult. This solution can be used to aggregate multiple A small-capacity channel forms a large-capacity channel. According to the structure of the front-end communication module, it is divided into multiple mechanisms such as 4x capacity expansion, 8x capacity expansion, and 16x capacity expansion. Not only that, the information transmitted by this solution is implemented via different links. After the packet is received, the link reselection and retransmission across the packet can be started quickly, ensuring the relative orderly arrival of the real-time information flow, thus avoiding waiting for timeouts, etc. Caused by the information flow. 2, high stability From single-link extension to multi-link aggregation transmission, it can provide better stability for emergency communication stability. By adopting a non-reliable transmission mechanism, the front-end does not need to wait for back-end information feedback, so the instantaneous jitter of a link can be detected within 5 ms. The data of the front-end drive can be used to better optimize the link and load configuration, thus effectively avoiding Link congestion caused by blind data transmission makes full use of all available channels to form a stable communication link. The system also provides forward error correction mechanism. The fault tolerance rate is 5% - 75% optional. Back-end restoration can be performed on the irresistible packet loss by configuring a reasonable redundant packet to further reduce possible data loss and further improve stability. . 3, high security Another advantage that single link expansion brings to multiple links is: data security. First of all, after unpacking the original data of the information flow in this scheme, it does not load each link according to the determined distribution ratio. The only load principle is based on the actual transmission capacity of each link within 5ms, each within 5ms. The amount of data transmitted on the link is changing, so it is difficult to perform packet capture analysis on a single link. Second, since the original data is transmitted via different physical links, the data of a single link is incomplete, and illegal users do not have availability even if they intercept data. Again, because of the indefinite amount of redundant data configured, it is difficult to parse data halfway unless it reaches the end. 4, high convenience This solution minimizes the use of first-line users. The front-end equipment is configured with only one switch key. Other configurations are self-adaptive. Whether it is the on-board system or the individual soldier system, personnel arrive at the site and communication support can be started within 10 seconds. 5, low cost The cost of this solution is about one-hundredth of that of the latter in relation to satellite communications with equal traffic and stability. At the same time, the installation cost of this solution has obvious cost advantages over other solutions. Fourth, application areas Applicable to the full scene data transmission scenarios under basic communications security, including policing/political affairs/city administration/garden/scenery/emergency rescue. It is specifically divided into two subdivision schemes, namely the on-board communication program and the individual soldier program. 1. Vehicle Communication System The on-vehicle communication security transformation is relatively simple and easy. The source is sent to the vehicle-mounted multi-link aggregation transmission route via the encoding device. The multi-link transmission route carries out reasonable load transmission after unpacking the original data. It has simple implementation, rapid startup, and Small consumption, anti-jamming and other characteristics. 2. Individual soldier system In the emergency place where it is difficult to get a vehicle in the field, this plan provides a single soldier program. It can be realized by carrying a single person, full power can achieve 8 hours of work, while providing replaceable batteries, support for hot swap. V.
