Embodiment Construction

[0012] Combine below Figure 1 to Figure 3 , the present invention is described in further detail.

[0013] Such as Figure 1 to Figure 2 As shown, a kind of train approaching alarm provided by the present embodiment includes an acquisition unit 10, a processing unit 20, and an alarm unit 30; the acquisition unit 10 is used to collect sound vibration signals of tracks and transmit the collected sound vibration signals to The processing unit 20; the processing unit 20 is used to process the sound vibration signal to obtain the distance and speed of the train approaching, and output a control signal according to the distance of the train approaching to drive the alarm unit 30 to issue an alarm message.

[0014] Specifically, the acquisition unit 10 in this embodiment is an acoustic sensor, which is installed close to the inner wall of the alarm housing.

[0015] It should be noted that the vibration emitted by the train running on the rails is a characteristic noise wave, and ...

Abstract

The invention discloses a train approach warning device and belongs to the technical field of electronic instruments. The train approach warning device comprises an acquisition unit, a processing unit and a warning unit, wherein the acquisition unit is used for acquiring sound vibration signals of tracks and transmitting the acquired sound vibration signals to the processing unit, and the processing unit is used for processing the sound vibration signals to obtain train approach distances and speeds and outputting control signals according to the train approach distances to drive the warning unit to send warning information. The train approach warning device has the advantages that the train approach warning device is small in size, portable and convenient to mount for defense and dismount; being multipurpose, the train approach warning device can be inserted into a turnout during turnout sweeping so as to be capable of warning when a train approaches and preventing turnout movement and clamping injury of turnout sweepers, can be attracted on the side face of a rail for defense during track construction protection, or can be arranged at a railway crossing to warn a coming vehicle.

Description

technical field [0001] The invention relates to the technical field of electronic instruments, in particular to a train approaching alarm. Background technique [0002] At present, with the increase of railway traffic volume and train speed, the workload of railway line construction and turnout cleaning has also increased dramatically. However, because railway workers have been working in the same environment for a long time and are familiar with the working environment and operating procedures, their sense of urgency tends to gradually diminish, and the sound from the running of locomotives and vehicles is difficult to arouse the vigilance of construction workers and turnout cleaning workers, resulting in vehicle injury accidents. Happens frequently. [0003] At present, many railway research institutes have carried out certain researches on train approaching alarms, and have also obtained some results. These alarms use special-purpose wired or wireless network communicati...
