Safety alarm device

Abstract

The invention relates to the technical field of safety alarm, in particular to a safety alarm device applied to sanitation operation.When the safety alarm device is used, the safety alarm device is arranged on the body of a sanitation worker, when the sanitation worker conducts the sanitation operation, an emitting unit emits a detection wave to a preset distance at preset intervals, the detection wave is used for covering a preset range, if a moving object exists in the preset range, a detection unit can determine whether the moving object exists in the preset range or not according to a reflected wave of the detection wave, and an alarm unit outputs an alarm signal if the detection result shows that the moving object exists in the preset range.Transmission of the detection waves is not restrained by light rays, and even if on the condition that the light rays are insufficient, the safety of the sanitation operation is greatly improved as long as the sanitation worker carries the safety alarm device.

Description

technical field [0001] The invention relates to the technical field of safety alarms, in particular to a safety alarm device used in sanitation operations. Background technique [0002] In recent years, sanitation workers in our country have become people with a high incidence of car accidents. On average, one sanitation worker is involved in a car accident every 5 days, and one sanitation worker dies every 73 days. There are many reasons why sanitation workers frequently cause car accidents. Objectively speaking, one is sanitation workers The job is on the road, and the environment is special, so the probability of encountering an accident is relatively high. Second, because of the uncivilized driving habits of drivers and passengers, drivers or passengers throw melon peels and shells out of the window and discard them. On the road, sanitation workers are artificially "set" a trap for car accidents. The third is the driver's uncivilized driving habits, such as carelessness ...

AI Technical Summary

Problems solved by technology

Sanitation workers in this age group are often not responsive enough, have low ability to predict accidents, and are often helpless when encountering emergencies, which leads to accidents

[0003] In order to improve the safety of the working environment of sanitation workers, sanitation workers must usually wear fluorescent clothing during sanitation work. There must be two color blocks on the fluorescent clothing, usually with a width of two centimeters, which can make other drivers or pedestrians walk within 60 meters. Sanitation workers can be seen from a distance, but this method has limited effect in poor light conditions

In the process of high-speed driving, the distance of 60 meters is relatively short, and the vehicle sometimes cannot brake or avoid in time due to the speed of the vehicle, so the above-mentioned method has a low effect on improving the safety of the sanitation work environment
