3. Simultaneous transmission of audio and video to realize multimedia transmission of video and data;
4. Multiple nodes cover the city, enabling mobile nodes to access at any time;
The long-distance transmission wifi module public security emergency command system scheme has the following characteristics:
1. Camera image bandwidth. Adaptively adjust the resolution and frame rate according to the channel bandwidth;
2. The image scheduling software can display multiple images at the same time, and supports local storage;
3. The small PTZ camera supports remote PTZ control and can be operated in real time on the background software;
4. The wireless ad hoc network system can support more than four broadcast voice calls, and the intra-group teleconference mode can be realized between nodes, and the operator can talk in two directions without buttons;
5. The wireless ad hoc network equipment control terminal can support more than four channels of broadcast video playback, and can realize the intra-group video conference mode;
6. The transparent IP data transmission network of the wireless ad hoc network system can realize the two-way communication of IP data between any nodes, and can construct image transmission modes such as multi-point uploading images/multi-node relay uploading images/two-way video conferencing;
7. Support TCP/UDP protocol, realize message, instruction, short message, real-time transmission of pictures and other data;
8. All wireless ad hoc network devices support external WIFI module, which is convenient for users to connect various forms of data terminals;
9. The background software of the wireless ad hoc network device of the long-distance transmission wifi module can display the network access of all nodes. Configure the parameters of all nodes in the off-network state;
Through the public security emergency command system, the interaction between the coordinated command of the public security department and the information plan can be realized, so that experts can realize. The responsible departments at all levels can successfully complete the discussion and decision-making, and minimize the inconvenience caused by the space distance. More emergency command systems.
Introduction to the wireless transmission system of wifi module for long-distance transmission in smart parks, all kinds of industrial parks in my country are developing rapidly, and the scale expansion is becoming more and more obvious. High-tech enterprises have settled in one after another. Enterprises have higher and higher requirements for the informatization of the park, and also put forward higher requirements for the service and management level of the park. The park has gradually become a centralized research and development site for high-tech industries, a high-tech enterprise cluster, and a high-tech product incubation and production base. Through the construction of informatization, the construction of industrial parks is interconnected. Driving industrialization with informatization is an important part of accelerating the development of industrial parks.
The reasons for the backwardness of the overall management model of parks in my country are mainly reflected in the following aspects:
1. The self-built local area network in the park needs to deploy a large number of optical fibers, network cables, switches and other equipment, and conventional overhead and buried construction methods must face the complex environment, which will eventually result in huge construction costs, the construction period is completely uncontrollable, and it is difficult to maintain in the later stage;
2. Due to inconvenient construction and cost constraints, the access network has not been deployed on a large scale in the park. Wired broadband is basically deployed at the entrance of the park or the management center, which cannot fully meet the network requirements of the park, such as the needs of mobile vehicle personnel and scanning personnel.
3. The information construction of the park is self-contained, the level of informatization is low, the remote and centralized control mode is lacking, the business system is closed, the software and hardware systems are relatively independent, the database is relatively independent, and information resources cannot be shared.
The three problems that need to be solved in the wireless transmission scheme of the long-distance transmission wifi module in the smart park:
1. The conditions of the park must be fully considered, and network coverage should be constructed wirelessly as much as possible to save a lot of construction costs and damage the existing park environment. At the same time, the wireless mode can greatly reduce the maintenance cost during use;
2. The difficulty of on-site power supply must be fully considered to meet the needs of the network when moving, and portable batteries should be used as much as possible;
3. In order to ensure satisfactory results, the complex environment of the workshop in the park must be considered, and the wireless transmission between devices must have a certain degree of penetration;
The intelligent park long-distance transmission wifi module wireless video surveillance system is mainly composed of the following three parts:
1. The front end is composed of high-definition network cameras, which are mainly used for video surveillance of roads and main places in the park. 720P, 1080P dome cameras or bolts are often used.
2. The middle end is composed of digital wireless video transmission equipment, which is mainly used for video transmission of each monitoring point. High-power wireless bridges and portable ad hoc network equipment are often used.
3. The back end is composed of monitoring equipment and data storage equipment, which is mainly used for real-time remote monitoring of each monitoring point, recording all monitoring videos, periodic retrieval and viewing, often using monitoring display, wireless transmission management system, etc.
The company has a professional smart park long-distance transmission wifi module wireless transmission scheme. On the premise of not destroying the existing environment of the park, a full-featured fixed and mobile service area on-site communication management system can be established; at the same time, the system also has high scalability, low latency, rapid deployment and rapid network link formation Deployment and automatic recovery. The communication service and management level of the park have been greatly improved.
