Description

Decentralized vehicle-mounted terminal scheduling system Technical Field The application relates to a decentralized vehicle-mounted terminal scheduling system, and belongs to the technical field of communication. Background The decentralization of the command and dispatch system is to break the physical space limitation of the traditional command center, so that the command decision is not limited to a fixed place any more, and the mobile vehicle-mounted command console can be utilized to realize information acquisition and decision making at any time and any place through a distributed architecture and multi-network fusion technology means. This transition not only increases the flexibility and response speed of the command and dispatch, but also enhances the reliability, risk resistance and emergency response capability of the system. Through the integration construction mobile vehicle-mounted platform with traditional management software and intelligent pad, vehicle-mounted platform passes through 5G network, lora and wifi, creates a "mobile command terminal", is applied to emergent command field. Most of the existing command scheduling systems are not fast enough in response speed to sudden events, wait for central scheduling when facing complex and changeable conditions, are not flexible enough in adaptability and adjustment capability, and have the problem of emergency response lag. Although the current vehicle-mounted command system (such as the prior art CN 112055365A) has basic terminal election and failover capabilities, four major limitations exist: (1) The security is that encryption measures are not adopted among the terminals, so that huge potential safety hazards exist, and network information is easily captured by other equipment to perform information counterfeiting; (2) The manual dependency is strong, an infrastructure (such as a base station or a central server) is required to be preset, a terminal list is completely invalid when a network is interrupted due to a disaster, and a newly added terminal cannot be efficiently networked; (3) The data is not synchronous, and a new command center needs to acquire the data again during switching, so that command delay (usually reaching the minute level) is caused; (4) The terminal cannot automatically find that, after losing connection with other terminals for some reasons, it cannot automatically join other networking terminals.
