Description
Technical field
The utility model relates to measurement mechanism, especially a kind of portable surveying instrument carrying out transfer of data.
Background technology
At present, the audience rating investigation method that each broadcasting station generally adopts is questionnaire type investigation method, by the investigation that the mode that fills in questionnaires is carried out about aspects such as program of radio station listening period, interest, customs to respondent, then manually gather, there is very large human error in the audience rating data drawn like this, be that investigator and respondent must exist certain subjective judgement, affect the authenticity of result, and the generation of data then have the very long cycle.
Utility model content
The purpose of this utility model is to provide a kind of portable type measuring, really can realize the record of broadcast audience rate and the conversion of statistics from manual operation to automatic electronic.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of portable surveying instrument carrying out transfer of data, it comprises MCU module, control panel, display module, radio module, GPRS wireless communication module, data center and SD card interface circuit, wherein MCU module is connected respectively at control panel, display module, radio module, MCU module is also connected with GPRS wireless communication module, the mutual communication of GPRS wireless communication module and data center.
Preferably, be provided with real time clock circuit, this real time clock circuit is connected with MCU module.
Preferably, described display module is LED display module, and LED display module is connected with MCU module through LED drive circuit, this LED drive circuit driving LED display module.
Preferably, described control panel is button and indicator light display circuit.
Preferably, described radio module is AM/FM radio receiver module.
After the utility model adopts said structure, this device take MCU module as core, by the communication of GPRS wireless communication module and data center, realize the record of broadcast audience rate and the conversion of statistics from manual operation to automatic electronic, and when GPRS wireless communication module interrupts, the data of collection are kept in SD card, by SD card interface, by the data importing data center in SD card, guarantee that the data collected can preserve in time.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of portable surveying instrument carrying out transfer of data, it comprises MCU module, control panel, display module, radio module, GPRS wireless communication module, data center and SD card interface circuit, wherein MCU module is respectively at control panel, display module, radio module is connected, MCU module is also connected with GPRS wireless communication module, the mutual communication of GPRS wireless communication module and data center, power supply is that modules is powered, this device take MCU module as core, by the communication of GPRS wireless communication module and data center, realize the record of broadcast audience rate and the conversion of statistics from manual operation to automatic electronic, and when GPRS wireless communication module interrupts, the data of collection are kept in SD card, by SD card interface, by the data importing data center in SD card, guarantee that the data collected can preserve in time.
Be provided with real time clock circuit, this real time clock circuit is connected with MCU module, realizes portable surveying instrument 24 hours and carries out record in seconds and storage to the investigation sample behavior of listening to incessantly, synchronous recording broadcast audience time and frequency.
MCU module is the core control part of this device, and all operations completing this measuring instrument controls.The work such as the collection of data, temporary, transmission, have MCU to come.Described display module is LED display module, and LED display module is connected with MCU module through LED drive circuit, this LED drive circuit driving LED display module.
Described control panel is button and indicator light display circuit, user is carried out switching on and shutting down, channel selection, the switching of receipts platform pattern by button, is listened to place switching, volume adjusting and AM/FM switching, sound is play by audio power amplifier circuit, and show this portable surveying instrument by indicator light and be in which kind of pattern, by all operations action of button, all by MCU module record, storage, send data center to by GPRS wireless communication module or SD card.
The above is preferred implementation of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection range of technical solutions of the utility model.
