The multifunctional integrated data collection system comprises a data transmission and level conversion module, a plurality of temperature and pressure sensing components and a computer. Each temperature and pressure sensing component is connected to the data transmission and level conversion module. The other end of the data transmission and level conversion module is connected with a port of the computer. The temperature and pressure sensing components transmit collected pressure and temperature data information to the data transmission and level conversion module in parallel through RS485 communication. The data transmission and level conversion module converts the received data information and finally the data information obtained after conversion is fed back to the computer in real time through RS232 communication. The multifunctional integrated data collection system for an indoor oscillation test platform is novel is concept and compact and reasonable in structure, is convenient to operate, can measure temperature and water level data at the same position at the same time and also can measure the temperature and water level data at different positions at the same time.

technical field The invention relates to a test equipment for obtaining hydrogeological parameters, in particular to a multifunctional integrated data acquisition system of an indoor oscillation test platform. Background technique At present, with the rapid development of social economy, engineering problems, resource problems and environmental problems related to groundwater science are becoming more and more prominent. All these problems involve the need to master the hydrogeological characteristics of the aquifer, especially the hydrogeological parameters of the aquifer. Therefore, at present, there have been many researches and developments on the experimental theories and methods for determining the hydrogeological parameters of the aquifer. , especially, the oscillation test method has been developed in recent years.

AI Technical Summary

Problems solved by technology

However, domestic research on oscillation tests has been relatively lagging behind for a long time. Due to the lack of a systematic and clear conclusion on the theoretical basis, scope of application, measurement standards, and operating procedures of oscillation tests in China, the research results of oscillation tests have not been implemented in practice. Widely promoted, there are few applied research reports and papers on the micro-water test

Therefore, in order to study the applicability and accuracy of the theory and technical methods of the vibration test in the actual field test in the relevant research universities and institutes in China, it is necessary to build an indoor vibration test platform to carry out the research work of the vibration test, but At present, when building an indoor oscillation test platform to carry out oscillation tests, the observation of the water level change in the aquifer is basically read manually through the change of the height of the piezometric tube. Due to the short test process of the oscillation test, if If you continue to use the traditional piezometer reading, you will not be able to read the piezometer reading well, because the oscillation test sometimes needs to read 10 water level change data within 1 second, so if you continue to use manual reading The change and distribution of the water level of the aquifer during the oscillation test will not be well understood. Therefore, an intelligent method is needed to quickly read the change of the water level. Therefore, it is necessary to develop a multifunctional integrated data acquisition system to meet the needs of the indoor oscillation test platform
