Data collection system based on Lora communication and networking method thereof

Abstract

The invention discloses a data collection system based on Lora communication. The system comprises a plurality of smart iron shoes, a plurality of relay nodes, a coordinator node and a smart anti-slip monitoring host. The smart iron shoes comprise sensor modules, iron shoe CPUs and iron shoe Lora communication modules. The relay nodes comprise relay CPUs and relay Lora communication modules. The coordinator node comprises a coordinator Lora communication module, a coordinator CPU and an Ethernet module. The plurality of smart iron shoes, the plurality of relay nodes and the coordinator node carry out wireless networking and communication based on a Lora communication protocol. The system is characterized by high efficiency, easy operation and high reliability. The smart iron shoes and the coordinator node carry out direct communication or carry out indirect communication through the relay node with the strongest signal. A state of an anti-slip device is monitored in real time. The system has very important significance and practical value in ensuring the safe operation of a railway.

Description

technical field [0001] The invention relates to the field of parking and anti-slipping of railway vehicles, and is especially suitable for realizing real-time data acquisition and management of on-site parking and anti-slipping of railway vehicles, in particular to a data acquisition system based on Lora communication and a networking method thereof. Background technique [0002] At present, the traditional anti-slip device has the following problems: it is difficult to monitor whether the anti-slip device is placed in place; it is also difficult to monitor whether the anti-slip device has been taken out when the car starts; the anti-slip device is stolen and cannot be reported in time; the collection, placement and removal of the anti-slip device The return and return are all done by manual operation, and the on-duty staff cannot promptly determine whether the anti-slip device is in a standardized and safe state; based on the simple point-to-point Lora communication method, ...

Problems solved by technology

[0002] At present, the traditional anti-slip device has the following problems: it is difficult to monitor whether the anti-slip device is placed in place; it is also difficult to monitor whether the anti-slip device has been taken out when the car starts; the anti-slip device is stolen and cannot be reported in time; the collection, placement and removal of the anti-slip device The return and return are all done by manual operation, and the on-duty staff cannot promptly determine whether the anti-slip device is in a standardized and safe state; based on the simple point-to-point Lora communication method, there are data packets lost in communication, and it is impossible to confirm whether the communication is through the most stable channel and the communication distance Issues that need to be further developed
