Dynamic shear rheometer temperature calibration device based on GPRS communication

Abstract

The invention provides a dynamic shear rheometer temperature calibration device based on GPRS communication, which is mainly characterized in that a communication port PF6 of a single chip microcomputer is connected with a clock line communication port SCL of a temperature sensor SMBus; a communication port PF7 of the single-chip microcomputer is connected with a data line connection communicationport SDA of the temperature sensor SMBus; a communication port GND of the single-chip microcomputer is connected with a communication port GND of the temperature sensor SMBus; a communication port 3.3V of the single-chip microcomputer is connected with a communication port VCC of the temperature sensor SMBus; a communication port PB10 of the single-chip microcomputer is connected with a line communication port R of the GPRS module; a communication port PB11 of the single-chip microcomputer is connected with a line communication port T of the GPRS module; the communication port 3.3V of the single-chip microcomputer is connected with a line communication port VMCU of the GPRS module; a communication port 5V of the single-chip microcomputer is connected with a line communication port VCC ofthe GPRS module; and the communication port GND of the single-chip microcomputer is connected with a line communication port GND of the GPRS module. The advantages are that the device has the characteristics of being portable and capable of supporting power supply in various modes and supporting secondary development and the like, the device can be connected with different server IPs according touser requirements, and the problems of temperature calibration and long-distance monitoring of the dynamic shear rheometer are solved.

Description

technical field [0001] The invention relates to a temperature calibrating device, in particular to a GPRS communication-based dynamic shear rheometer temperature calibrating device. Background technique [0002] Highway transportation plays an indispensable role in the development process of our country. It has become an important development element of the current highway construction to promote the development of my country's highways in the direction of informatization and intelligence. In the transportation industry, the asphalt PG grade evaluation has been applied by most of the expressway construction in China. In the "Technical Specifications for Asphalt Pavement Construction" and "Asphalt and Asphalt Mixture Test Regulations", the asphalt PG classification test is specified accordingly, and the dynamic shear rheometer is used to measure the dynamic shear modulus and phase of asphalt. horn. Dynamic shear rheometer is a high-precision instrument and equipment, which ...
