Description

Light curtain warning system for children to take escalator independently

Technical Field

The utility model belongs to the technical field of special equipment safety, concretely relates to take light curtain alarm system of automatic escalator alone to children.

Background

The escalator system is used as an important electromechanical device in stations, airports and public places with large pedestrian flow. Has the characteristics of wide application range, high technical requirement, wide safety influence range and the like. Because the holding capacity of the escalator is increasing day by day, and the number of users rises rapidly, passenger injury accidents of the escalator are frequent. For example, 126 passenger injuries occur in the year 2020 on Chongqing subway No. 10 line, wherein 117 passenger injuries of the escalator account for 92.8% of the total number of passenger injuries. The reasons for the occurrence of accidents can be classified into two aspects, namely, poor working conditions of the equipment on one hand and improper use of passengers on the other hand. In recent years, the proportion of passenger accidents caused by improper use of passengers has rapidly increased, and the proportion of passenger accidents particularly caused when children take escalators alone is the most prominent.

Aiming at the injury accidents caused by the dangerous behaviors of children taking the escalator, the traditional technical means has insufficient prevention effect. In recent years, with the rapid development and application of infrared pyroelectric sensors (PIR sensors), the PIR sensors have the possibility of analyzing human behaviors and postures, and will bring new solutions for recognizing dangerous behaviors of passengers of the escalator. Traditional voice alarm is probably ignored by the passenger who drives in the wrong direction, in order to improve the warning effect of system to the passenger, an electronic light curtain that interception performance is strong, warning effect is good is urgently needed.

Reference numerals:

1-a detection column; 11-low sensor; 12-high sensor; 2-warning door frame;

21-a laser; 22-smoke generator.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The light curtain warning system as shown in fig. 1 comprises a detection column 1 and a warning doorframe 2, both of which are arranged on an entrance channel of the escalator, wherein the detection column 1 is positioned in front of the warning doorframe 2.

The detection column 1 is specifically provided with two groups of position sensors which are respectively positioned at two sides of an entrance channel of the escalator, the detection column 1 is provided with two groups of position sensors which are respectively a low position sensor 11 and a high position sensor 12, the low position sensor 11 is arranged at the lower part of the detection column 1, the height of the low position sensor is matched with the height of a child, for example, the height of the low position sensor is set below 1 meter, but the height of the low position sensor is guaranteed to be more than 20cm as far as possible so as to avoid the problem of sensor failure caused by foot lifting and crossing in normal walking, and the high position sensor 12 is arranged at the upper part of the detection column 1, and the height of the high position sensor is matched with the height of an adult, for example, the height of the high position sensor is set above 1.4 meters; the position sensors are used for detecting the passing condition of people, and when people pass through the position sensors, the position sensors are shielded, so that the position sensors are triggered, and the SM04-IRA01 type pyroelectric infrared sensors can be selected as the two groups of sensors; whether the children take the escalator alone is judged through the trigger condition identification of the two groups of infrared sensors in the embodiment, wherein when only the low-level sensor 11 is triggered, the children are judged to take the escalator alone without accompanying with adults.

The warning door frame 2 stretches across an entrance channel of the escalator, a plurality of lasers 21 are arranged on upright posts on the side edge of the warning door frame 2, the lasers 21 are arranged at equal intervals in the vertical direction, the lasers 21 are emitted from one side of the door frame to the other side, and the lasers 21 specifically adopt a point-like laser generator with performance parameters of 532nm-50 mW; the laser 21 is used for displaying a laser column in the range of the door frame, so that the intercepting and warning functions in visual sense are achieved. In order to enhance the display effect of the laser column, a smoke generator 22 is arranged on a cross beam at the top of the warning doorframe 2, and the scattering openings of the smoke generator 22 are vertically arranged downwards and are uniformly distributed along the horizontal direction of the cross beam; by arranging the smoke generator 22, suspended smoke or water mist is dispersed in the air within the range of the warning door frame 2, so that the Tyndall effect of laser in the air is enhanced, and the display effect of a laser column is also enhanced.

Through above-mentioned light curtain alarm system, when having children to take the staircase alone through detecting post 1 detection discernment, laser instrument 21 and smoke generator 22 work of cooperateing for demonstrate multichannel laser post in warning door frame 2, play the warning interception effect with this.

Can also set up bee calling organ or voice broadcast ware in warning door frame 2 to when accomplishing the interception of visual warning, still the cooperation uses voice warning, with this warning children or near adult of furthest, avoid children to take the staircase alone.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
