Universal serial bus (USB) flash disk type electronic temperature recorder

Abstract

The invention relates to a temperature record output device, in particular to a universal serial bus (USB) flash disk type electronic temperature recorder which can directly generate an Adobe portable document format (PDF). The USB flash disk type electronic temperature recorder comprises a temperature meter and a USB flash disk, wherein the USB flash disk and the temperature meter are integrated. The USB flash disk type electronic temperature recorder is characterized in that data of the temperature meter in the measurement process are stored in the USB flash disk of the temperature meter, and when the USB flash disk is connected with a USB interface of a computer, the USB flash disk can transmit an imaged report file in the Adobe PDF to the computer. In the generated PDF report file, a trend curve of measurement temperature and time, the configuration time of the temperature recorder, a measurement interval, measurement starting time, measurement stopping time and points of measured data amount are described in detail; and moreover, statistical parameters such as maximum temperature, minimum temperature, mean temperature, mean kinetic temperature (MKT), high temperature alarm limit, low temperature alarm limit and standard deviation of measurement data are described.

Description

technical field [0001] The invention relates to a temperature record output device, in particular to a U-disk electronic temperature recorder which can directly generate Adobe PDF format. Background technique [0002] Temperature recorders are widely used in temperature detection and recording in the fields of drug and food cold chain transportation, storage, fresh-keeping and other industries. However, under the current technical conditions, the measured temperature data often cannot be synchronously connected with the computer for a short period of time. It is necessary to first transmit the original measurement data to the computer through a reader or serial port, and then through the management software in the computer according to the Raw data draw trend curves and calculate statistical parameters. Such a temperature data transmission method is time-consuming and laborious, which increases the workload; and errors may occur during the transmission process, which brings...

However, under the current technical conditions, the measured temperature data often cannot be synchronously connected with the computer for a short period of time. It is necessary to first transmit the original measurement data to the computer through a reader or serial port, and then through the management software in the computer according to the Raw data draw trend curve and calculate statistical parameters

Such a temperature data transmission method is time-consuming and laborious, which increases the workload; and errors may occur during the transmission process, which brings instability to the temperature detection work
