Permanent-magnet magnetic levitation rail transit control system based on 5G communication technology

A permanent-magnet maglev rail transit control system based on a 5G communication technology, comprising an intelligent control center and a 5G communication platform, wherein

• the intelligent control center comprises an electrical control system, a data exchange device, a communication device and a central server;
• the electrical control system and the data exchange device is in communication connection with the central server;
• the central server is in communication connection with the communication device;
• the electrical control system is configured to drive a permanent-magnet maglev train to run according to instructions of the central server;
• the data exchange device comprises a data storage array, a data management unit and an input and output interface;
• the data storage array is used for data storage, and is connected with the data management unit through the input and output interface;
• the data management unit is in communication connection with the central server;
• the data management unit is configured to select corresponding data from the data storage array according to a request of the central server and transmit the corresponding data to the central server;
• the 5G communication platform comprises a 5G base station and a train communication support unit;
• the 5G base station is arranged along a running route of the permanent-magnet maglev train;
• the train communication support unit comprises a front-end communication module, a back-end communication module, a controller and a WiFi transmission module;
• the front-end communication module, the back-end communication module and the WiFi transmission module are in communication connection with the controller;
• the controller is in communication connection with the central server;
• the front-end communication module and the back-end communication module are separately installed at a front end and a tail end of the permanent-magnet maglev train;
• each compartment of the permanent-magnet maglev train is provided with the WiFi transmission module;
• the communication device is in communication with the 5G base station;
• and
• the 5G base station is connected to an external Ethernet to provide a wireless communication service, and services such as installation of the 5G base station are provided by operators;
• in the train communication support unit, the controller is configured to acquire a current running position of the permanent-magnet maglev train from the central server, control the back-end communication module to be in communication connection with a current nearest 5G base station according to the current running position of the permanent-magnet maglev train and the installation position of the 5G base station, and control the front-end communication module to be in communication connection with a next approaching 5G base station;
• when the permanent-magnet maglev train gradually leaves away from the nearest 5G base station and gets close to the next 5G base station, signals received by the back-end communication module gradually become weaker, while signals received by the front-end communication module gradually become stronger;
• when the controller detects that the signals received by the back-end communication module are weaker than that received by the front-end communication module, that is, the 5G base station connected with the front-end communication module becomes the current nearest 5G base station, the controller controls the back-end communication module to disconnect the communication connection from the original 5G base station and to be in communication connection with the 5G base station connected with the front-end communication module;
• when the controller monitors that the back-end communication module is in stable connection with the current nearest 5G base station, the front-end communication module is controlled to be disconnected from the current connected 5G base station and is controlled to be connected with an approaching 5G base station of the permanent-magnet maglev train according to the current running position of the permanent-magnet maglev train and the installation position of the 5G base station;
• and the WiFi transmission module is in communication connection with the controller to transmit WiFi signals so as to provide a wireless communication signal for a passenger and equipment in each compartment,
• wherein the permanent-magnet maglev rail transit control system further comprises a train security system, wherein the train security system comprises a face recognition unit, an in-station monitoring unit, an object detection unit, a communication unit and an alarming unit;
• the face recognition unit, the in-station monitoring unit, the object detection unit and the alarming unit are in communication connection with the communication unit;
• the communication unit is in communication connection with the 5G base station;
• the face recognition unit is configured to acquire face information of the passenger and send the face information to the central server through the communication unit so as to realize real-time online face recognition, and the central server sends an instruction about whether the passenger is allowed to pass or not to the face recognition unit according to recognition results;
• the object detection unit is configured to detect baggage and belongings of the passenger and send detection information to the central server through the communication unit, and the central server identifies whether there are one or more specific objects or not;
• when the central server discovers that there are the one or more specific objects, the communication device sends an alarm control signal to the alarming unit, and the alarming unit gives an alarm;
• and the in-station monitoring unit is configured to monitor the behaviors of people on a platform and send monitoring information to the central server through the communication unit, the central server judges whether there are one or more specific behaviors or not, and if so, the central server sends an alarm control signal to the alarming unit through the communication device, and the alarming unit gives an alarm.
