1、 Product Introduction

The intelligent experimental equipment management system is an automated networked remote collection, monitoring, and management system for experimental equipment that integrates sensing technology, automation control technology, wireless communication technology, and network technology. The 'Experimental Testing and Monitoring System' consists of three main parts: the 'Automatic Data Collection and Processing System', the 'Remote Data Transmission System', and the 'Data Monitoring Analysis and Processing Center'.

The intelligent testing equipment management system monitors the real-time test data of the universal machine and press in the mechanical laboratory during the process of pulling steel bars and pressing prefabricated stones, and calculates the tensile strength, yield strength, maximum force, and test pass rate of the universal machine, as well as the compressive strength and pass rate of the press. All monitoring data is automatically connected to the network and uploaded to the server. Owners and supervisors can remotely monitor experimental data in real-time through a browser.

2、 System operation process

Due to the variety of manufacturers and models of universal machines and presses used in the laboratory, including manual, digital, and automatic ones, the technical level varies. According to different situations, different information technologies are used to install a "data automatic acquisition and processing system" on the computer control host of the press and universal machine in each supervision and section laboratory. The required models are set up to automatically process machine models, test parameters, etc., ensuring that all displayed data is consistent.

At the same time as displaying data and controlling the press or universal machine on the laboratory computer, the system automatically extracts relevant test data from the generated database through the "data remote transmission system". Then, through the "data monitoring, analysis and processing center", these test data are analyzed to extract real-time values of the measured parameters. When the preset upper and lower limit alarm settings are reached, warning and control signals will be issued to prompt the operator to take relevant measures. The alarm can detect parameter changes in real time and accurately, and can provide reliable and error free warnings for a long time. At the same time, the "data remote transmission system" is used to send test data, warning information, related processing, etc. to the owner, supervisor, and other platforms.

3、 System functions

1 Automatically create reports and ledgers

The data monitoring equipment shall establish a report ledger according to the laboratory name, which can intuitively retrieve and view engineering information such as test time, sample number, test type, design strength, pressure bearing area, age, load, etc. of each press. It is possible to perform historical queries on the testing data of press and universal machine laboratories.

2 Eliminate concrete with substandard strength

Set design strength or strength standards in the system, automatically retrieve unqualified test reports, and mark them in red font. Arrange quality and safety inspections as soon as possible to prevent the occurrence of quality hazards. The handling results can also be recorded and queried in the ledger.

3 Effectively controlling the discreteness of concrete strength

The system has the function of quickly conducting mathematical and statistical evaluation according to the engineering parts, intuitively reflecting the quality status of concrete in each engineering part. According to the size of the sample, the correct evaluation method can be selected. Through software quality analysis, it is possible to more intuitively reflect the signs of data dispersion, timely check for possible factors that may affect the quality of concrete, such as material quality, construction technology, and engineering management, and correct them in a timely manner.

4 Comprehensive statistics

The system conducts comprehensive statistical analysis of a large amount of data. When the experimental data indicators show non normal distribution and the confidence level of the data is outside 5%, it indicates the existence of quality risks. The system will automatically recommend a special inspection.

5 comparative analysis

The system provides a comparative analysis function for the strength of concrete with the same model and grade conditions, and issues a comparative analysis report.

6 Comparative test

The system has a comparison test function. As long as the same samples are distributed to each laboratory for testing, the system will automatically generate a "comparison test summary report" after uploading the test data and report. The report records information such as consensus strength, mean value, standard deviation, qualified number, and deviation value, directly reflecting the technical level of each laboratory.

4、 System features

1. The terminal program extracts data in real-time, while the B/S system displays data in real-time.

2. Analyze the qualified and unqualified data of the experiment and provide a network solution process.

3. Automatically generate a curve graph of force values versus time.

4. It is possible to perform historical data queries on the testing data of press and universal machine laboratories.
