Problems solved by technology

[0004] (1) High labor intensity, time-consuming and labor-intensive, and low detection efficiency
[0005] ⑵Due to the heavy reliance on labor in the entire testing process, the testing process lacks controllability, resulting in a series of management and monitoring problems, and the accuracy of the testing results will also be affected
[0006] ⑶In the actual testing process, it is greatly affected by human factors, which has a negative impact on the quality of the project, the reputation of the testing agency, and the interests of consumers
[0007] (4) The detection time of manual operation is very limited, usually only during the daytime, and the flexibility of detection time is poor

Embodiment 1

[0045] Such as figure 1 , 2 Shown, be a kind of concrete compressive strength automatic detection method of the present invention, comprise the following steps:

[0046] 1. According to the information of the concrete test block provided by the sample sending unit, including the age of the concrete test block, collection time, size, strength grade, serial number, etc., the concrete test block in this embodiment is a concrete test block of 150×150×150mm block (24 days old), enter the information of the concrete test block into the computer, and synchronize the information of the concrete test block to the central control system. The central control system generates a management code for each concrete test block, and each concrete in the control system The management code of the test block corresponds to the information of the concrete test block, the management code is set on the concrete test block, and the entire work process is controlled by the central control system;

[...

Embodiment 2

[0066] The difference between this embodiment and the embodiment is that the concrete test block is a 150×150×150mm concrete test block (the age is 28 days), and the basic information of the concrete test block is entered first, and then placed in the first pressure On the sensor 1, the first pressure sensor 1 feeds back the pressure signal to the central control system 13, and the central control system 13 starts the transport belt, and the concrete test block is transported through the infrared scanning device, and the information of the test block is fed back to the central control system 13, and the central control system 13 The control system 13 judges that the sample is an aged sample according to its age of 28 days, opens the push separation mechanism 3, closes the push separation mechanism 5, and directly transports the test block to the storage rack of the sample temporary storage room 7 through the belt and the push separation mechanism Above, the central control syst...

Embodiment 3

[0068] The difference between this embodiment and the embodiment is that the concrete test block is a concrete test block (age of 30 days) of 150 × 150 × 150mm, the management code is set on the concrete test block, and the basic information is entered (information input Incomplete), then placed on the first pressure sensor 1, the first pressure sensor 1 feeds back the pressure signal to the central control system 13, the central control system 13 starts the transport belt of the detection system, and the concrete test block is transported through the belt and passes through the infrared scanning device, Infrared scanning equipment detects that the sample information is incomplete, and immediately gives an alarm prompt. The central control system 13 activates the push separation mechanism 3 and the conveyor belt to transport the sample to the temporary storage platform, and puts it into the detection system again after the information is completed.

Abstract

The invention discloses a concrete crushing strength automatic testing method and system. The method comprises the steps of 1, inputting the information of concrete test blocks into a computer and synchronizing the information to a central control system, wherein a management code is generated for each concrete test block by the central control system; 2, conveying the concrete test blocks to enable the concrete test blocks to pass through the scanning management codes; 3, conveying the concrete test blocks reaching the predetermined age to a test platform; 4, conducting pressure testing on the concrete test blocks, acquiring test data, obtaining a test result through calculation, and outputting the test result. By the adoption of the method and system, high automation degree can be realized, automatic conveyance and testing are decided and started through a computer, unattended testing is achieved, labor intensity is relieved, and working efficiency is improved; the accuracy of test data can be guaranteed, and the reliability of tested sample data can be guaranteed; automatic testing is conducted through the central control system according to acquired sample information, no time limitation exists, and testing can be conducted at any time as long as relevant parameters are well set.

Description

technical field [0001] The invention relates to an automatic detection method of concrete compressive strength and a detection system using the method, which can realize unattended automatic detection of concrete compressive strength. Background technique [0002] Concrete compressive strength testing, as one of the most routine testing items in engineering projects, has a great demand in actual testing. However, at present, most concrete compressive strength tests in China are highly dependent on manual work. During the process of concrete compressive strength testing, sample information entry, sample storage and transfer, sample strength testing, post-test cleaning, data collection and comprehensive processing, etc. All steps require manual operation. [0003] There are the following defects in the manual operation of concrete compressive strength testing: [0004] (1) High labor intensity, time-consuming and labor-intensive, and low detection efficiency. [0005] ⑵Beca...
