Description
Technical field
The utility model relates to intelligent transportation field, is meant a kind of being placed on the carriageway surfacing especially, is used to detect the traffic flow analysis instrument that vehicles such as car speed, travel direction, vehicle classification dynamically reach static information.
Background technology
Along with development economic and society, the raising of living standards of the people, automobile has entered huge numbers of families as a kind of walking-replacing tool, the vehicle guaranteeding organic quantity fast lifting, the traffic congestion phenomenon of avenue and highway is also just more and more serious thereupon, particularly at the arterial traffic of some large-and-medium size cities, traffic congestion takes place especially constantly.For addressing this problem, often most of fund is all put into and enlarged in city size, the construction of rectification build road-based infrastructure, but the speed that enlarges city size, rectification build road is unable to catch up with the speed that traffic pressure increases far away, the just aggravation of following of traffic pressure.But then, many path resources do not make full use of, and cause a large amount of wastes.Traffic information system and traffic control system just are based on this purpose and produce, and the traffic detector is an indispensable instrument of gathering traffic information data.
Existing traffic detector all is to use the toroid winding detection technique, and its principle of work is to utilize the toroid winding be embedded under the carriageway surfacing, and whether respond to has vehicle to pass through or exist.This detecting device have cost low, easy for installation, highly sensitive, be subjected to advantages such as climate effect is little.But in actual use, increase because of factors such as road construction, surface deformation make the spoilage of coil, will enter the highway main body when changing installation and maintenance, influence communications and transportation, cause cost to raise, maintenance workload is bigger; Its data extract for traffic flow is also very limited, generally only can detect car speed.
Summary of the invention
The purpose of this utility model is to provide a kind of and is installed on the carriageway surfacing, can detect vehicles such as car speed, travel direction, vehicle classification and dynamically reach static information, and by external data interface is set the information uploading that collects be downloaded; Firm in structure, cracky not; And simpler, the lower-cost traffic flow analysis instrument of installation and maintenance.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of traffic flow analysis instrument, be installed under the carriageway surfacing, comprise housing, supply module, magnetic imaging sensing module, AD modular converter, central processing unit, memory module, data-interface, it is characterized in that: described supply module links to each other with magnetic imaging sensing module, AD modular converter, central processing unit, memory module, data-interface, described magnetic imaging sensing module links to each other with the AD modular converter, and described AD modular converter, memory module and data-interface all link to each other with central processing unit.
As preferably, described supply module, magnetic imaging sensing module, AD modular converter, central processing unit, memory module, data-interface all are installed in the sealing rigid housing.
As preferably, described data-interface is RS232, RS485 or wireless communication interface.
As preferably, described supply module is wired power supply, accumulator or the solar battery group with mu balanced circuit.
As preferably, described magnetic imaging sensing module comprises the detecting element that at least one is made up of strong permeability magnetic material.
As preferably, described central processing unit is FPGA or arm processor.
Principle of work of the present utility model is: because the difference of car body ferrous metal distribution of material, the deformation effect of magnetic flux line generation is different over the ground, the voltage-time curve that is drawn is also inconsistent, when vehicle passes through, just start working by the magnetic imaging sensing module of in housing, installing, collect corresponding magnetic induction change information, the information of collecting is sent in the AD modular converter by designated lane, the AD modular converter becomes central processing unit can discern the digital signal of handling analog signal conversion, central processing unit to the certain algorithm process of corresponding information via after, whether have vehicle pass through, and can calculate the type by vehicle if can judge, running time, length, relevant informations such as speed.And the relevant information after central processing unit will be judged stores jumbo memory module into.The traffic flow analysis instrument can be communicated by letter with PC by RS232 or GPRS communication interface, the data upload in the jumbo memory module is arrived PC, to be correspondingly processed.
Compared with prior art, the utility model not only can detect car speed, can also detect vehicle multidate information and static informations such as travel direction, type of vehicle; And be provided with external data interface, and the information uploading that collects is downloaded, easy to use; Firm in structure, cracky not; And installation and maintenance are simple more, cost is lower.
