Problems solved by technology
At the same time, the system operates under high-intensity and complex conditions for a long time, making the possibility of failures unabated. Therefore, the analysis of operating data is a necessary link for troubleshooting and maintenance of train control systems
[0003] Troubleshooting and maintenance of the train control system needs to be analyzed using the recorded data of on-board equipment during train operation. The recorded data includes status information of key on-board equipment, data interaction information of each module, and interaction information with the ground. However, currently When the train control system equipment fails, it is still necessary to rely on the on-site personnel to get on the train to download the operation and status data of the train control equipment
At the same time, due to the variety of functions, on-site personnel need to download the data of different devices through cumbersome processes, which consumes a lot of manpower and time

The embodiment of the invention provides a communication system and method based on LoRa and visible light, equipment and a storage medium. The communication system based on the LoRa and the visible light comprises a vehicle-mounted equipment and a roadside equipment, the vehicle-mounted equipment comprises a first LoRa communication unit and a first visible light communication unit; the roadside equipment comprises a second LoRa communication unit and a second visible light communication unit; the first LoRa communication unit is set to communicate with the second LoRa communication unit so as to determine whether a service data transmission condition is satisfied between the vehicle-mounted equipment and the roadside equipment; and the first visible light communication unit is set to communicate with the second visible light communication unit under the condition of determining that the service data transmission condition is met so as to complete transmission of service data. According to the wireless communication scheme provided by the embodiment of the invention, high-speed and safe wireless data transmission is realized by fully utilizing respective advantages of LoRa communication and visible light communication.
Description
technical field [0001] The present invention relates to but not limited to the field of wireless data transmission, and specifically relates to a communication system, method, device and storage medium based on LoRa and visible light. Background technique [0002] With the integration of information technology and the railway industry, it has brought a profound impact on railway construction, operation and maintenance, etc. Intelligent railway has become the trend of future railway development. With the increasing number of train operating equipment and the continuous change and improvement of on-board control functions, the complexity of the equipment and functions of the automatic train control system (ATP) makes the workload of system maintenance increasing day by day. At the same time, the system operates under high-intensity and complex conditions for a long time, which increases the possibility of failures. Therefore, the analysis of operating data is a necessary link ...
