Overflow type anti-span guardrail triggered by medium and short distance induction

Abstract

The invention discloses an overflow type anti-span guardrail triggered by medium and short distance induction. The overflow type anti-span guardrail mainly comprises a column and a fence, wherein thecolumn is internally provided with an infrared sensor, a PLC, a small motor, a miniature electronic water pump I, and a miniature electronic water pump II, a plurality of pipes and a water tank, and the fence is composed of an upper horizontal bar, a middle horizontal bar, a lower horizontal bar, a hollow vertical bar and a solid vertical bar. By connecting the horizontal bars and the vertical bars in the fence through the pipes in the column and the water tank, a water circulation structure composed of the upper horizontal bars, the hollow vertical bar, the middle horizontal bar, the lower horizontal bar and the water tank is formed; an object is identified by an infrared sensing technology, and signal commands are processed and transmitted by the PLC to control the overflow of the wholeupper horizontal bar to achieve the goal of preventing people from spanning. The overflow type anti-span guardrail has high safety performance and high efficiency, and can be used as an option for anyguard fence.

Description

technical field [0001] It relates to the field of building facilities, in particular to an overflow type anti-crossing guardrail triggered by medium and short distance induction. technical background [0002] Guardrails are relatively common in daily life. They are mainly used in residences, highways, public places and other occasions to play the role of isolation and protection. Although the guardrail is small, its role should not be underestimated. With the maturity of product development, guardrails have also become an important branch of the construction industry, and the classification of guardrails is also increasing. The isolation and protective functions of traditional guardrails are effective in most cases, but they cannot stop everything, such as school fences, traffic guardrails, scenic spot guardrails, etc. People often cross and climb guardrails. If you learn from others, more and more people will climb the guardrail one after another, so the guardrail will onl...

Problems solved by technology

[0003] At present, a municipal traffic guardrail with the application number CN201721387920.9 is disclosed. It adopts the design of adding sharp anti-crossing tooth marks on the horizontal bar on the guardrail. It is also a common way to warn people to prohibit crossing. Although this design Simple and effective, but it is dangerous and not suitable for installation anywhere

[0004] There is also an anti-crossing road guardrail with application number CN201520639790.8, which discloses the use of an infrared camera to detect whether people have climbed over the guardrail. If someone climbs over the guardrail, the infrared camera will transmit information to the alarm in the form of an analog signal. , so that the alarm will alarm and warn people not to cross; although this warning method is not dangerous, it is obviously insignificant in the role of expulsing people who hurdle, and the efficiency is low
