Separate cascading guardrail falling off sensing device

Abstract

The invention relates to a separating cascade guardrail disengagement sensing device which comprises a disengagement sensing mechanism fixed between a guardrail stand column and a guardrail cross beam. The disengagement sensing mechanism comprises an electronic switch module, a plug and a socket, wherein the electronic switch module and the socket are fixed in the guardrail stand column, the electronic switch module is electrically connected with the socket, the plug is fixed in the guardrail beam, and the plug and the socket are connected in a plugging mode. Separating cascade guardrail disengagement sensing devices are installed on all the stand columns of a road guardrail, the position state of each section of the guardrail can be sensed, the structure is simple, installation is convenient, cost is low, a circuit processing module is only powered on when the road guardrail inclines and disengages for a certain length, the current of the electronic switch module is at the uA level when inclination or disengagement does not occur, and the problem of the power source management of an alarming system is effectively solved.

Description

technical field [0001] The invention relates to the field of road facilities, in particular to a separate cascaded guardrail fall-off sensing device for road guardrails. Background technique [0002] On the traffic roads such as urban ground traffic roads and traffic trunk roads in suburban junctions, in order to make pedestrians, non-motor vehicles and motor vehicles further abide by traffic rules and reduce the occurrence of traffic accidents, in terms of technology, mobile vehicles are widely used at home and abroad. traffic barrier. However, this type of traffic guardrail is easily toppled by vehicles, high-intensity winds, or even twisted and pushed away from the original position, which can easily cause secondary traffic accidents. This puts forward higher requirements for the maintenance and management of traffic barriers. At present, some technical means have been used to realize the intelligent management of traffic guardrails. For example, the Chinese patent docu...

Problems solved by technology

At present, some technical means have been used to realize the intelligent management of traffic guardrails. For example, the Chinese patent document CN102063780A titled "Highway Guardrail Impact Location and Alarm System and Method Based on Internet of Things Technology" is based on Internet of Things. The on-site terminal adopts the polling method for detection, which makes the system more complicated, and each component must be in working condition all the time, which increases the construction complexity; another example is the Chinese patent document CN103354014A titled "Road Traffic Guardrail Intelligent Management System", which uses acceleration The detection of sensors and active working methods requires uninterrupted power supply for the detection circuit in the system, which increases the complexity of the system

In the existing technology, it can be seen from the preferred scheme that there are still common defects: 1. Cannot effectively sense the connection status and dumping situation of each section of guardrail; 2. The detection method makes some or all circuits, including the microprocessor, always in the Working state, resulting in waste of electric energy, the equipment is easy to age
