A low-power train approaching early warning system and method based on lora local area networking

Abstract

The invention discloses a low-power consumption train approach pre-warning system and method based on LoRa (long-range) local area network establishing. The low-power consumption train approach pre-warning system and method based on LoRa local area network establishing comprises a first uplink detection node, a second uplink detection node, a plurality of relay nodes, a first downlink detection node, a second downlink detection node and an alarming terminal; the first uplink detection node and the second uplink detection node are both arranged on an uplink track; the first downlink detection node and the second downlink detection node are both arranged on a downlink track; the first uplink detection node is linked with the second uplink detection node, the plurality of relay nodes, the second downlink detection node and the first downlink detection node in sequence to form a main network; and the main network performs information interaction with the alarming terminal on the peripheryin a polling manner to as to mutually form a local area network. According to the low-power consumption train approach pre-warning system and method based on LoRa local area network establishing, technical problems that the transmission distance of the existing automatic train approach pre-warning method is limited in regions with poorer communication statuses, the existing automatic train approach pre-warning method cannot ensure that construction personnel can accurately receive alarming signals, and the practicability is poor can be solved.

Description

technical field [0001] The invention belongs to the field of railway operation safety, and more specifically relates to a low-power train approach early warning system and method based on LoRa local area networking. Background technique [0002] Railway track construction is an important work to ensure the normal operation of railway transportation. If the train approaches the construction section and the railway site construction personnel cannot be notified in advance to evacuate to a safe area, it will easily lead to dangerous situations. In view of this, the train approaching early warning method is widely used at present. [0003] Nowadays, train approach early warning methods adopted in railway track construction include manual monitoring methods and automatic early warning methods. [0004] Manual monitoring methods mainly include job scheduling and manual observation, but these two methods cannot fully meet the safety requirements of railway track construction, espe...
