Fire and disaster relief command and communication ad hoc network solutionFire and disaster relief command and communication ad hoc network solution overview Due to the rapid growth of social economy, the types and quantities of urban construction are increasing, the population is becoming more and more densely inhabited, the types and properties of various combustibles are becoming more and more complex, and the uncertain factors in the building structure, road layout, water source distribution and other elements have greatly increased, all of which have increased the difficulty of fire fighting and rescue activities of the fire fighting force. For a long time, the commander on the fire ground mainly relies on experience and intuition to command the troops to carry out rescue activities, and the fire command often has great blindness, and lacks the scientific and technological basis of the on-site command, so the success rate and efficiency of fire fighting and rescue are low. On the basis of integrating and utilizing existing resources, Wanlan Communication has launched the use of advanced technology to establish a multimedia fire communication dispatching and command system integrating communication, command and dispatch, with a high degree of intelligence, to respond quickly to various alarms of the public, and to realize the diversification of the province's fire fighting and rescue alarm information reception, the accuracy of the fire rescue location, the scientific compilation of dispatched forces, and the rapid dispatch of dispatch orders and fire rescue information dynamics. The informatization of fire command and the visualization of revealing fire information will ultimately realize the province-wide digital alarm reception, dispatch and command, improve the rapid response and scientific decision-making ability of the fire brigade, effectively respond to all kinds of major and malignant fire accidents, minimize the losses caused by disasters, and ensure the safety of people's lives and property. Background description On April 3, 2022, according to the Fire and Rescue Bureau of the Ministry of Emergency Management, in the first quarter, a total of 219,000 fires were reported across the country, with a total of 625 people killed and 397 injured due to fires, with direct property losses of 1.52 billion yuan. Compared with the same period last year, the number of fires, injuries and losses decreased by 11.6 percent, 8.5 percent and 20.5 percent respectively, and the number of fatalities increased by 4.9 percent, of which 29 were major fires, an increase of 6 over the same period last year. Analysis of the current situation When major disasters occur (such as fires, earthquakes, tsunamis, floods, mudslides, major traffic accidents, etc.), they are usually accompanied by the damage and paralysis of infrastructure such as communications, and the means of communication used in ordinary times are basically ineffective, and the affected areas are basically in a state of information islands, and a powerful emergency command wireless communication system is a necessary condition for effectively carrying out rescue and disaster relief operations. In this regard, Wanlan Communication has a complete set of solutions, that is, emergency command wireless ad hoc network communication system. In the event of an emergency and disaster, it provides a unified emergency communication system that can carry voice, image, and data. The integration of ad hoc network voice communication, video transmission, data scheduling and other functions can realize the unified coordination of command and communication between urban areas to counties, county government offices to township offices, township offices to natural village committees, rapid response and joint action, truly realize the linkage of emergency disaster response, and effectively respond to sudden public events. Wanlan ANYMESH ad hoc network radio can quickly deploy at the disaster site, quickly build a command and communication network, and provide real-time information for disaster relief command, so that the command can quickly understand and grasp the disaster and loss situation, reasonably deploy disaster relief resources, formulate disaster relief plans, unify the command of the joint work of various disaster relief units, and take effective measures to quickly carry out disaster relief operations to minimize disaster losses. Scenario introduction City, county (district) consumer management departments need to be in the event of a fire, the rescue team can quickly rush to the scene to set up a rescue communication link, rescuers need to realize voice and video communication between personnel through the link, and the command center and on-site command vehicle can also command the rescue work in real time through the wireless link. Solve the problem of emergency rescue command and communication in various extreme situations. ANYMESH ad hoc network radio has good radio communication ability, and can quickly form a centerless network through the free networking between ANYMESH ad hoc network radio stations without relying on the public network. This system is composed of ANYMESH handheld radio, ANYMESH knapsack radio, ANYMESH vehicle-mounted radio, ANYMESH airborne radio and ANYMESH ad hoc network base station equipment and integrated emergency command information platform, which can build a broadband self-organizing communication network with wide area coverage, flexible and mobile, and supports multi-service types. The location, status and other information of all connected nodes are summarized in real time to the back-end network management system for unified scheduling, management, and control. solution The maximum point-to-point communication distance of the limit coverage of NYMESH ad-hoc network radio is 160 kilometers, and the maximum system bandwidth is 100M, which realizes the real-time processing capability of voice, video, image, message, positioning and other information, and realizes horizontal integration and communication with the existing digital ultra-short wave and satellite communication. 方案设计如下：
As shown in the figure above, the design of the entire consumer rescue command and communication scheme is divided into four parts. The portable node part of the ad hoc network: the intelligent terminal of the front-end ground detector personnel is connected with the ANYMESH ad hoc network individual soldier carrying node device through WiFi, and the individual soldier nodes of the ad hoc network can communicate with each other through mesh Ad hoc network airborne node part: the ad hoc network airborne node equipment carried by the UAV in the air and the self-organizing network individual soldier carrying node equipment can also be interconnected through mesh networking, and the communication distance from the general UAV to the ground detection personnel can reach more than 10-20KM; Emergency communication command vehicle node part: install an ANYMESH ad hoc network vehicle node equipment on the emergency communication command vehicle 20 kilometers away from the front-end detection personnel at a distance, and the ad hoc network vehicle node equipment builds a wireless communication network with the ad hoc network airborne node equipment on the UAV through a wireless MESH link The main command center part: the emergency communication vehicle can build a communication link with the command center through 4G/5G and nearby communication base stations or through satellite signals. Equipment introduction Ad hoc network handheld
