Embodiment Construction
[0019] The features and principles of the present invention will be described in detail below, and the examples given are only used to explain the present invention, not to limit the protection scope of the present invention.
[0020] The detection method of the guardrail collision is to attach multiple sections of optical fiber to the expressway corrugated plate along its length direction. Each section of optical fiber can be one or more. A signal transmitter is arranged at one end corresponding to each section of the optical fiber, and a corresponding signal receiver is arranged at the other end.
[0021] Sequentially number each section of optical fiber, and the signal receiver transmits the detection signal to the guardrail maintenance department through wireless. Correspondingly, the guardrail maintenance department is equipped with signal processing and display equipment. If there is a problem with the corresponding road section guardrail, the signal receiver cannot tra...

The invention discloses a guardrail collision detection method. A plurality of sections of light-guide fibers are attached to the highway corrugated plate in the length direction of the highway corrugated plate. One end of the light-guide fiber is provided with a signal emitter, and the other end is provided with a signal receiver. All the sections of light-guide fibers are numbered in sequence, and the signal receiver transmits detection signals to a guardrail maintenance department in a wireless mode. One or more light-guide fibers are attached to the outer side or the inner side of the highway corrugated plate in the length direction. One end of the light-guide fiber emits a light source, and the other end receives a signal. In this way, the receiver actually performs collision localization. One or more light-guide fibers are attached to the outer side or the inner side of the highway corrugated plate in the length direction. One end of the light-guide fiber emits a light source, and the other end receives a signal. If the guardrail is collided, the optical fiber is broken, the receiving end loses the signal, and a signal alarm is sent out. The device is composed of multiple sections of optical fibers and a receiver, so that the receiver actually performs collision localization.
Description
technical field [0001] The invention relates to the technical field of highway maintenance, in particular to a detection method for guardrail collision. Background technique [0002] China has now entered a period of rapid development of expressways, and the construction of expressways has largely promoted the development of local economies. However, during the use of expressways, there are generally phenomena such as severe early damage to the road surface, and the service life cannot meet the design requirements. However, in the process of maintenance, if the construction quality cannot be effectively controlled, it may seriously affect the economic and social benefits of the expressway. [0003] The status quo of maintenance and treatment of highway guardrails, the maintenance and operation mechanism is relatively backward. Too much attention has been paid to the construction of highway guardrails, but the maintenance work has been left behind. Too little money is spen...
