Online power supply and data acquisition equipment are stablized in configuration along burying sensor under road surface and needing.Road is that coverage area is big, edge
The structure that line style extends, unlike the engineering structures such as bridge, building, pass of the road due to can not characterize structure feature
Key component, therefore the monitoring system of road needs the data transmission network to the sense line and complexity for laying long range along the line
Network, to increase the cost of monitoring system.Patent CN2591264Y discloses a kind of road piezoelectric type power generator.The invention
Including road surface cover plate, below pit, beam and be affixed on the piezo-electric generating containing multilayer build-up piezoelectric patches thereon in length and breadth in hole
Device.When vehicle crosses road surface cover plate, the pressure that cover plate generates makes the piezoelectric patches on beam deform, to obtain electricity
Energy.The patent extracts energy from ambient vibration, can solve sensor powerup issue to a certain degree, however substantially can only be
Vehicle can not reach the requirement that data acquisition equipment stablizes online power supply by power supply in rear a period of time, therefore not solve
The problem of data acquire.In addition, the technology that the patent is protected could not organically combine power generator with pavement structure,
When installation and operation will road pavement road structure and sensing device damage so that the system can not both be used continuously, tool
There is some potential safety problems.
Carbon fiber is a kind of novel sensing material, since it is with high-strength, corrosion resistant physical characteristic, than traditional gold
Belong to resistance strain type sensor and has more long-term stability.Patent CN103868445A discloses a kind of long gauge-length carbon fiber and answers
Become sensing technology, the technology is by comparing different types of carbon fiber sensor, it was found that the carbon fiber for characterizing linear strain is special
Sensing length is levied, highly sensitive and small transversal effect stabilization sound state strain measurement is realized.By by carbon fiber and coagulation
For on the one hand can use the physical property of carbon fiber itself in road structure after the fusion of the materials such as soil, steel, composite material
The mechanical property of structure is improved, while being conducive to its sensing capabilities for meeting strain measurement and developing various forms of intelligent Components,
Realize the intelligent sensing material of high-performance, Gao Naijiu.
The research for making a general survey of domestic and international related roads monitoring, is primarily present sensing network currently used for roadway monitoring system and supplies
The problem of electricity, great number data acquisition equipment lead to sensor-based system increased costs.For this purpose, we, which have developed one kind, is suitable for road surface road
Road engineering is mated formation, and situ configuration power supply and data collector are not needed, with good Quick Acquisition characteristic and economic benefit
Road information collection system.
