Abstract
The invention is a portable traffic information acquisition system, which consists of PDA and GPS receiver. The PDA sets up a database and interface to inter-communicate with computer. The GPS and PDA are inter-connected. PDA gets roads basic attribute information from computer, then PDA automatically generate electronic survey sheets for field data collection according to the information. PDA as a handheld device is taken to the scene for data collection. The collected traffic information inputs to the database in PDA directly, meanwhile GPS receiver transmits the scene position information to PDA. PDA then transmits the data that have been in the database to computer for the follow up of data processing, analysis and store.
Description
Technical field
The present invention relates to physical field, relate in particular to the measurement and the recording technique of transport information, particularly a kind of portable traffic information data collecting system.
Background technology
The collection of traffic information data is all significant for theoretical research, traffic programme, traffic administration or traffic evaluation.In the prior art, gather the technological means that traffic information data remains general practicality by the mode of hand-written record, the mode of the hand-written record papery investigation form that need be prepared in advance, then when carrying out on-site data gathering with the data book write record on the papery investigation form, at last with papery investigation form filing or by manually with the storage of the input of the data in papery investigation form robot calculator.But because object, content, place or the purpose difference of each traffic study, the form of each traffic study is also different.Even once investigation also can increase a lot of same forms along with the difference of period.Therefore, in order to finish data acquisition, all need to make or change different forms, and same form needs to prepare number of iterations again, the preliminary preparation burdensome that makes data acquisition at every turn.In addition, carry a large amount of papery investigation forms and carry out the data acquisition inconvenience to the scene, cause condition of work not good, as clipboard, stopwatch and the pen of holding form in the hand, can't handle other special event, especially for worker in car for a long time, be difficult to adjust the state that own posture arrives the most comfortable.And the form of each cell is the same, causes the investigator to record wrong cell easily.And, also need the certain reaction time just can sit in the right seat for new hand, to some degree, caused the reduction of work efficiency and the raising of error rate.In addition, the data that are recorded on the papery investigation form are difficult for backup, lose breakage easily, influence safety of data, and adopt the artificial method of importing that data are imported robot calculator and store, make mistakes easily, influence the accuracy of data, the typing work of each image data is the expensive again time dry as dust.Also have and since with the mode of writing with data recording to paper, add the situation that will change paper, might cause some traffic study to have little time record, thereby cause investigation inaccurate; Or Dynamic Data Acquiring point also can influence investigation result with the inconsistent issuable error of static data measuring point.
Summary of the invention
The purpose of this invention is to provide a kind of portable traffic information data collecting system, described this portable traffic information data collecting system to solve in the prior art with transport information hand-written be recorded on the paper carrier the data acquisition modes workload greatly, lose easily, data are made mistakes easily, the technical matters of inefficiency.
This portable traffic information data collecting system of the present invention is by personal digital assistant device (Personal Digital Assistant, hereinafter to be referred as PDA), GPS receiver (Global PositionSystem, hereinafter to be referred as GPS) and the personal computer formation, wherein said PDA is connected by serial communication interface with the GPS receiver, PDA is provided with Computer Communications Interface, PDA is connected with personal computer by described Computer Communications Interface, be provided with first database in the personal computer, be provided with second database among the PDA, store the basic attribute data of road in described first database.
The present invention also provides a kind of method of utilizing above-mentioned portable traffic information data collecting system to gather traffic information data, wherein, at first the basic attribute data with the road stored in first database is delivered in second database, the input media that utilizes PDA then at the scene is to input of second database and storage traffic data, the field position information data input that simultaneously the GPS receiver is received is also stored second database into, and the traffic data with the collection in worksite in second database is delivered in first database then.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes embedded type terminal equipment PDA and database technology to realize the collection in worksite of information data easily, and by having realized the automatic record of field position information with combining of GPS receiver.Aspect file processing, by utilizing the information interaction of PDA and computing machine, utilizing existing basic data on the computing machine before the data acquisition, after data acquisition, can also easily field data be passed to and carry out subsequent treatment in the computing machine.The present invention utilizes PDA as the carrier of service data acquisition software and the media of data recording, change traditional written record mode into software application based on PDA, man-machine conversation by data acquisition personnel and PDA, realize the record of data, and realize the transmission of data by the data-interface of PDA and PC.The self-clocking function that utilization simultaneously itself is had and realize automatic positioning function with the extended function of GPS compatibility.
Purpose of the present invention, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
Description of drawings
Fig. 1 is the illustrative view of functional configuration of a preferred embodiment of a kind of portable traffic information data collecting system of the present invention.
Fig. 2 is the process flow diagram of a preferred embodiment of a kind of portable traffic information data collecting system of the present invention.
Embodiment
As shown in Figure 1, a kind of portable traffic information data collecting system of the present invention is made of personal digital assistant device PDA1, GPS receiver 2 and personal computer 3, wherein said PDA1 and GPS receiver 2 are connected by serial communication interface, PDA1 is provided with Computer Communications Interface, PDA1 is connected with personal computer 3 by described Computer Communications Interface, be provided with first database in the personal computer 3, be provided with second database among the PDA1, store the basic attribute data of road in described first database.
As shown in Figure 2, the present invention also provides a kind of method of utilizing above-mentioned portable traffic information data collecting system to gather traffic information data, wherein, at first the basic attribute data with the road stored in first database is delivered in second database, the input media that utilizes PDA1 then at the scene is to input of second database and storage traffic data, the field position information data input that simultaneously GPS receiver 2 is received is also stored second database into, and the traffic data with the collection in worksite in second database is delivered in first database then.Undertaken follow-up according to processing by personal computer 3.
