Fig. 1 is a structural block diagram of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figure 1, a portable measuring instrument capable of data transmission includes an MCU module, a control panel, a display module, a radio module, a GPRS wireless communication module, a data center, and an SD card interface circuit. The panel, the display module and the radio module are connected, the MCU module is also connected with the GPRS wireless communication module, the GPRS wireless communication module communicates with the data center, and the power supply supplies power for each module. Communication with the data center realizes the conversion of the recording and statistics of radio listening rate from manual operation to electronic automation, and when the GPRS wireless communication module is interrupted, the collected data is stored in the SD card, and through the SD card interface, the SD The data in the card is imported into the data center to ensure that the collected data can be saved in time.

A real-time clock circuit is provided, and the real-time clock circuit is connected with the MCU module, so that the portable measuring instrument can record and store the listening behavior of the survey sample in seconds without interruption for 24 hours, and record the broadcast listening time and frequency simultaneously.

The MCU module is the core control part of the device, and completes all operation controls of the measuring instrument. Data collection, temporary storage, transmission and other work are all done by MCU. The display module is an LED display module, and the LED display module is connected with the MCU module through an LED driving circuit, and the LED driving circuit drives the LED display module.

The control panel is a button and an indicator light display circuit. The user can switch the machine, select a channel, switch the receiving mode, switch the listening location, adjust the volume and switch AM/FM through the button. The sound is played through the audio power amplifier circuit, and through the instruction The light shows which mode the portable measuring instrument is in. All the operation actions through the buttons are recorded and stored by the MCU module, and transmitted to the data center through the GPRS wireless communication module or SD card.

The above description is only a preferred embodiment of the utility model, and of course it cannot limit the scope of rights of the utility model. Replacement does not depart from the protection scope of the technical solution of the utility model.
