Abstract

The utility model discloses a resident trip survey data acquisition system which consists of mobile equipment, a resident trip survey module, a local data module, a local resident trip survey database module, a local resident trip survey data export module, a survey data remote receiving module, a remote database module, an earphone, a global position system (GPS) module and a personal computer (PC), wherein the mobile equipment is connected with the resident trip survey module, the GPS module and the external earphone; the resident trip survey module is respectively connected with the local data module and the local resident trip survey database module; the local resident trip survey data export module is connected with the remote database module; and the survey data remote receiving module is connected to the PC. After the resident trip survey data acquisition system is used, the questionnaire quality and the survey precision are greatly improved, the manual recording cost is saved, and the resident trip survey is realized by means of electronization and informatization.

Description

The resident trip survey data acquisition system (DAS)

Technical field

The utility model relates to a kind of data acquisition system (DAS), relates in particular to a kind of resident trip survey data acquisition system (DAS).

Background technology

Existing resident trip survey means are mainly by design resident trip survey questionnaire, by visit personnel Door-to-door Interview, at specific accessed crowd, fill in questionnaires face to face or keep somewhere questionnaire, thereby gather the situation of family characteristic information, personal characteristic information and the trip information of resident in certain time period.After reclaiming questionnaire, questionnaire coding and the typing of questionnaire data by unified form the database file based on excel or access, to offer data analysis application unit.Such technique for investigation is in the present situation in the face of the existing difficulty of registering one's residence, the difficulty of filling in a form, and the technical bottleneck of existence displays gradually.These gordian technique bottlenecks are:

(1) data acquisition precision is not high;

(2) traffic study microzonation offshoot program is irreversible;

(3) can't collect the trip routing information;

(4) the form recovery difficult is big;

(5) data typing work is heavy and the cycle is long;

(6) Quality Control Links is too much;

(7) questionnaire is checked before the typing;

(8) primary investigation data accumulation inconvenience;

(9) the investigation cost is big.

Because existing resident trip survey has adopted the papery questionnaire to carry out door-to-door survey, at sample households, we must print corresponding questionnaire and investigate with " traffic zone code pattern " before the investigation, questionnaire also needs to organize lot of data typing personnel to carry out the data typing after reclaiming and finishing, these working links not only need to expend certain material and personnel cost, also increased a lot of time costs, therefore needed a kind of device systems that utilizes electronization and information-based means to carry out resident trip survey to planning.

The utility model content

Carry out the relevant issues that resident trip survey exists in order to solve the artificial papery of above-mentioned employing, the utility model provides a kind of resident trip survey data acquisition system (DAS).

For solving above technical matters, the technical solution adopted in the utility model is: a kind of resident trip survey data acquisition system (DAS) is characterized in that: it is derived module, the long-range receiver module of enquiry data, teledata library module, receiver, GPS module and PC by mobile device, resident trip survey module, local data module, local's trip survey database module, local's trip survey data and forms; Described mobile device and resident trip survey module, GPS module and external receiver are connected; The resident trip survey module is connected with local data module, local's trip survey database module respectively; Local's trip survey data derive module and are connected with the teledata library module; The long-range receiver module of enquiry data is connected on the PC.

The resident trip survey module is made of investigation and verification standard customized module thereof, an investigation input validation module, electronic chart rendering module, address searching locating module, trip path calculation module.

The local data module is made of electric map module, investigation item and verification standard configuration file module thereof.

Application of the present utility model has improved questionnaire quality and investigation precision greatly, has saved the typing cost of labor, has realized utilizing electronization and information-based means to carry out resident trip survey.
