Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in Figures 1 and 2, the transmitter 50 is a box as a whole, with a handle 1 on the top of the box, and a photoelectric induction device 2 next to the handle 1. There are wireless transmitting equipment and lithium batteries inside the box. Lithium battery voltage display table 3, wireless transmitting antenna 4, power switch 5, wireless transmitting power switch knob 6, wireless transmitting channel selection knob 7, lithium battery charging interface 8 and lithium battery power indicator light 9. Such as figure 2 As shown in the schematic diagram, the lithium battery supplies power to the photoelectric sensing device 2, etc. When the locomotive arrives, the locomotive covers the warning device, and the photoelectric sensing device 2 detects the arrival information of the locomotive. At this time, the wireless transmitter works to emit ...

Abstract

The invention relates to a railway line construction double-direction safety pre-warning device and method. The device comprises an emitter and two responders, and the emitter comprises a photoelectric induction device, a wireless emission device and an emission lithium battery; the emitter is mounted on the rail, and the photoelectric induction device is arranged upwards; each responder comprises a wireless receiving device, a signal processing device, a response lithium battery and a buzzer; one responder is mounted beside a railway line construction person, and the other responder is placed on a locomotive; when the locomotive passes through the emitter, the two responders receive signals of the emitter at the same time to generate pre-warning, and after the railway line construction person hears a pre-warning signal, the person can be evacuated from the construction site in time; and when a locomotive driver hears the pre-warning signal, the driver is on the alert and attentions whether the construction person in front of the locomotive safely evacuates or not, so that the driver can take necessary emergency measures. The emitter and the responder A are portable and are powered through the lithium batteries; the responder B is powered on through an onboard power source. The method is simple, the field application is convenient, and extra power supply or construction is not needed.

Description

technical field [0001] The invention relates to a safety early warning device and method, in particular to a two-way safety early warning device and method for construction along a railway. Background technique [0002] There are many forms of traditional early warning for construction safety along the railway line. Most early warning equipment uses equipment instead of manual early warning to improve the safety of protection and reduce the waste of manpower. [0003] The equipment early warning that adopts at present, some adopt the laying very long signal cable on the construction site; Some adopt the infrared shaft temperature detection method etc., these methods all are the information that the locomotive will arrive at the construction site to notify the construction personnel of the construction site, safe evacuation. However, when the locomotive passes the early warning device or transmitter, the locomotive driver does not know whether there is construction work on th...
