Abstract

The embodiment of the invention provides a method, a device, and equipment for monitoring the state of an identification card. According to the method, an acceleration of a to-be-detected identification board in a three-dimensional direction is collected; according to an expression, a sum acceleration a of the to-be-detected identification board is determined, wherein ax expresses an accelerationof the to-be-detected identification board in an x direction, ay expresses an acceleration of the to-be-detected identification board in a y direction, and az expresses an acceleration of the to-be-detected identification board in a z direction; whether the to-be-detected identification board falls down or is loosened is determined based on the sum acceleration; and if so, alarm information is generated and the generated information is sent to a terminal. Therefore, when the to-be-detected identification board is loosened, the phenomenon can be discovered timely.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of road traffic, and in particular to a method, device and equipment for state monitoring of a signboard. Background technique [0002] Traffic signs are graphic symbols that display traffic regulations and road information. They are used to regulate and control traffic, prompt road conditions, and remind and guide drivers to reduce the incidence of traffic accidents. Due to the influence of external force and natural factors, signboards often loosen or fall, which not only causes huge losses to the traffic management department, but also brings huge traffic safety hazards. [0003] At present, the damage of signboards is usually found through manual inspections or reports from the masses. [0004] However, the inventors have found that there is a problem that the signboard cannot be found in time after the identification plate becomes loose or falls in the mode of manual inspectio...
