Description

[0001] Safety guidance block for gait signals and direction display improved visibility and discrimination [

[0001] The present invention relates to a safety inductive block, and more particularly, to a safety inductive block for guiding a walking signal and a moving direction, which improves visibility and discrimination ability by using a driving signal and an LED, will be.

In general, the safety guide block forms a protrusion pattern on a sidewalk block installed on the entrance line of a crossing board or on a waiting line of a subway, so that when a visually impaired person senses a protrusion pattern formed on a sidewalk block through a foot or a cane, To be recognized,

In accordance with the Enforcement Regulations of the Act for the Promotion of Convenience Promotion of Elderly Persons with Disabilities, etc., a linear or protruding pattern of a certain size is formed on the top of a 30cm x 30cm x 6cm board block.

This is because the eyes of blind people are all invisible, but only one eye is blind, or the blindness is visible in the case of visible amblyopia.

However, there is a problem that visibility deteriorates due to dirty inductive block over time. The built-in LED module inside the sidewalk block connects the signal module with the signal lamp, and when the signal light is turned on, the LED lights automatically and high visibility and discrimination power Although the induction block to be imparted has been developed,

This is because the controller 42 or the melody box 43 of the signal lamp 40 and the plurality of inductive blocks are connected by a cable and can be operated by supplying power,

In addition, since it is vulnerable to moisture, frequent failures due to short-circuiting occur, and even if a part of the faulty induction block is replaced, there is a problem that it is inconvenient to disassemble all the sidewalk blocks installed in the vicinity and re- There is a problem that a lot of labor costs arise.

In addition, if some of the inductive blocks fail and stop, the remaining inductive blocks connected to the inductive block are disconnected and the operation of the peripheral inductive blocks automatically stops.
