Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
The invention provides a kind of subgrade settlement monitoring system, be applied in the railway security supervisory system.As shown in Figure 1, subgrade settlement monitoring system provided by the invention comprises: subgrade settlement detection system, monitoring host computer system and subgrade settlement sensing system.Wherein subgrade settlement sensing system sensing subgrade settlement change information transfers to the subgrade settlement detection system, the subgrade settlement detection system is accepted to change sensing signal and transfer to the monitoring host computer system behind the subgrade settlement change information, and the monitoring host computer system stores is also processed the subgrade settlement change information that receives.The signal of monitoring host computer system processes sensor output, this subgrade settlement change information real-time Transmission is to monitor terminal the most at last, and the information of monitor terminal in can the Real-time Obtaining monitoring host computer is consulted the subgrade settlement situation, in order in time process dangerous situation.
As depicted in figs. 1 and 2, this subgrade settlement sensing system is comprised of a plurality of sensors, the series connection of sensor multiple spot.Sensor preferred fiber sensor is preferably selected fiber-optic grating sensor, and Fibre Optical Sensor also is connected with light source.Certainly, the sensor of subgrade settlement sensing system is not limited only to Fibre Optical Sensor, and other sensor devices with same function still can be realized the sensing to subgrade settlement.The quantity of Fibre Optical Sensor can be according to the engineering monitoring demand series connection of reality, and for example two to dozens of.When subgrade settlement occured, Fibre Optical Sensor is simultaneously distortion also, externally embodies the variation of the light signal of Fibre Optical Sensor sensing.Along with the time changes, each point that detects in real time just becomes a curve, i.e. roadbed bulk deformation curve.The Fibre Optical Sensor of subgrade settlement sensing system can be along railway bed laying, and light source sends light signal in real time.After the subgrade settlement monitoring system started, when railway bed generation sedimentation, the subgrade settlement of Fibre Optical Sensor sensing changed, and the subgrade settlement change information is sent to the subgrade settlement detection system with the light signal form.According to the characteristics of Fibre Optical Sensor, this subgrade settlement sensing system can be monitored subgrade settlement, but and not worked by electromagnetic interference (EMI), the high real-time online of precision.
As depicted in figs. 1 and 2, the subgrade settlement detection system among the present invention arranges monitoring module, and monitoring module comprises signal receiving module, signal processing module and communication module.The subgrade settlement detection system gathers the subgrade settlement change information of subgrade settlement sensing system transmission, changes this subgrade settlement change information and transfers to the monitoring host computer system by communication link.After the subgrade settlement monitoring system started, the signal receiving module of subgrade settlement sensing system received in real time the subgrade settlement change information of subgrade settlement sensing system real-time Transmission and transfers to signal processing module; Signal processing module is collected the subgrade settlement change information that signal receiving module receives, and becomes electric signal transmission to communication module the analog signal conversion of this subgrade settlement change information; Subgrade settlement change information after communication module will be changed transfers to the monitoring host computer system.
As depicted in figs. 1 and 2, subgrade settlement detection system and subgrade settlement sensing system preferably adopt two groups of subgrade settlement sensing systems and two groups of subgrade settlement detection system double copies patterns.Two groups of subgrade settlement sensing systems are laid in respectively the track bed both sides, measure in real time the subgrade settlement of railroad track both sides and change.Two groups of subgrade settlement detection systems work alone fully, and the subgrade settlement change information of respectively reception group subgrade settlement sensing system transmission does not interfere with each other.Adopt the double copies mode greatly to improve the reliability of system and the degree of accuracy of sensing.
The course of work of subgrade settlement monitoring system provided by the invention is such: after the present invention starts, light source sends light signal in real time, the subgrade settlement change information of the real-time sensing railway of the Fibre Optical Sensor of subgrade settlement sensing system, and to this subgrade settlement change information of subgrade settlement detection system real-time Transmission.The signal processing module of subgrade settlement detection system is collected the subgrade settlement change information that signal receiving module receives, and becomes electric signal transmission to communication module the analog signal conversion of subgrade settlement change information; Subgrade settlement change information after communication module will be changed transfers to the monitoring host computer system.The monitoring host computer system transfers to monitor terminal with this subgrade settlement information storage and after processing, and the subgrade settlement change information of monitor terminal in can the Real-time Obtaining monitoring host computer consulted the subgrade settlement situation, in order in time process dangerous situation.Before the subgrade settlement change information that monitor terminal obtains surpassed alarm threshold value, this subgrade settlement monitoring system just can display the subgrade settlement infotech and can real-time report.
By adopting subgrade settlement monitoring system provided by the invention can improve the monitoring information content of disaster prevention system, realized the Real-Time Monitoring to railroad bed settlement information.The antijamming capability of equipment is strong simultaneously, adopts the many Fibre Optical Sensors of two groups to improve availability, the safety and reliability of system.Can accomplish uninterrupted monitoring, before roadbed change to surpass safe range, the effectively generation of the accident such as pre-train derailing prevention.
The above has been described in detail subgrade settlement monitoring system provided by the present invention.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention it being done all will consist of infringement of patent right of the present invention, will bear corresponding legal liabilities.
