Warning board

Abstract

The invention provides a warning board made of an abrasive resistant material, wherein the warning information content of the warning board comprises general information and variable information, and the general information and the variable information are respectively expressed by a general information module and a variable information module. Preferably, the warning board is divided into an adhesive layer, an abrasive resistant basic layer and a surface coating. The general information module and the variable information module are made of the same or similar materials with the same thickness and are respectively composed of corresponding character modules and baseplates. The warning board is used with a flaky embedded or cylindrical separate memory chip without an external power. By adopting the technical proposal of the invention, electronic management can be achieved on concealing equipment and facilities, and the probability that the warning board is stolen is lowered; an embedded structure adopted in the invention avoids information loss due to surface wear, thus prolonging the service life; and by adopting the design of the character modules, each character corresponds to a production die which can be reused, thus lowering the production cost of the warning board.

Description

technical field [0001] The invention relates to a warning sign. Background technique [0002] Warning signs are a common and effective means of municipal management. For example, in the management of hidden equipment and facilities such as underground pipelines, metal or wear-resistant material warning signs are set on the ground. [0003] Warning signs usually include general information and change information in content. General information includes high-voltage cables, communication pipelines, water supply pipelines, heat pipelines, street lamp pipelines, public trenches, sewage pipelines and other categories of definition names, and change information includes road names, numbers, connection methods, etc. In actual use, it is usually used to corrode, spray, and engrave information on metal plates such as stainless steel plates and aluminum plates, or to spray and engrave information on rubber and plastic plates, and fix them in areas or positions that need to be warned ...

AI Technical Summary

Problems solved by technology

[0004] However, there are some problems in adopting the above-mentioned methods and materials: metal warning signs have recycling value, and are often lost due to criminals stealing; Lost meaning; if the rubber and plastic warning signs are made by die stamping and engraving, it can effectively solve the problem of wear resistance, but it is impossible to make one brand and one model for changing information

[0005] These problems limit the actual use of existing warning signs and cannot be mass-produced and applied
