Embodiment

[0053] In this embodiment, the models of the two electronic balances selected are respectively LT15KA-1 and LT3KA-1, the data acquisition terminal selects an STM32 single-chip microcomputer and an external reset button, the camera is a DS-2CD3410FD-IW wireless network camera, and the speaker is DS-925 ceiling speaker, the microphone is SY-100A microphone.

[0054] This system can realize the monitoring of the crushing value test of coarse aggregate and the screening test of coarse and fine aggregate. The following will introduce them respectively:

[0055] The coarse aggregate crushing value test is used to measure the ability of the stone to resist crushing under gradually increasing loads. In this embodiment, three samples of the same quality are taken in the test process to carry out parallel tests. The test process is roughly as follows: firstly, the sample is evenly loaded into the test mold; then the test mold with the sample is placed on the press to start the press, an...

Abstract

The invention discloses a real-time monitoring system and method for an aggregate test, comprising an electronic balance, a data collection terminal, a test data processing module, a host computer, a monitoring device and a remote server; one end of the data collection terminal is connected to the RS232 serial port of the electronic balance, and the other One end is connected to the test data processing module, and the test data processing module is set inside the upper computer, and the upper computer and the monitoring device are connected to the remote server through the Internet. Number the test sample, set the storage format, and transmit real-time information to the remote server; measure the weight data of each stage of the test sample and transmit it to the data acquisition terminal and then to the test data processing module, store and generate test data according to the storage format; transmit the test data to a remote server for analysis and processing to generate a test report. It realizes the transparent management of the test data and test process of the aggregate test, guarantees the authenticity of the test data to the greatest extent and improves the engineering construction management level.

Description

technical field [0001] The invention belongs to the field of highway construction, and relates to a real-time monitoring system and method for an aggregate test. Background technique [0002] With the vigorous development of highway construction in our country, the usage of cement concrete and asphalt mixture is increasing year by year. Aggregate is a kind of aggregate that plays the role of skeleton and filling in the mixture, and its quality has a great influence on the performance of the concrete made. Among them, poor gradation of coarse and fine aggregates will reduce the workability of concrete mixtures; unqualified mechanical properties of coarse aggregates will greatly affect the quality of the project. Therefore, in order to meet the requirements of highway engineering for the quality of aggregates, my country has issued relevant specifications requiring the crushing value test of coarse aggregates and the screening test of coarse and fine aggregates for aggregates...
