In 20 19, the Ministry of Education issued JY T 061919 "Configuration Standard for Physics Teaching Equipment in Junior High School", which guided the configuration of physics experimental equipment in junior high school, including the configuration requirements for physics inquiry laboratories, from computers to data collectors to sensors and experimenters.
According to the standard, the relevant requirements for configuring the data collector in the geophysical exploration laboratory scheme are: "It can communicate with computer USB interface or wireless communication, and support four-channel parallel data acquisition with wired connection. The recommended configuration number is1~13 ";
The software for collecting and processing experimental data should be "Simplified Chinese Interface". After the data collector is connected to the computer, it can identify the data collector and its status by its own weight, display experimental data or curves in real time, and has a variety of data processing and analysis tools for experimental data and graphics. The experimental data can be exported to table or text format (see the screenshot of Wei Chengya's digital software) ".
The scheme configuration of junior middle school physics inquiry laboratory should include computer, data collector, software, sensors and supporting accessories, among which there are many kinds of sensors and accessories. The recommended configuration number is generally: 1~ 13 sensors, such as force sensors, micro-force sensors, temperature sensors, surface temperature sensors, etc. 13~25 experimental instruments (accessories), such as friction tester, or 1~25, such as liquid internal pressure tester; Demonstrators (accessories) 1~2 sets, such as buoyancy principle, the relationship between fluid pressure and flow rate, etc.
It should be noted that the accessory parameters configured in the geophysical laboratory scheme must meet the standard requirements. For example, the friction testing machine requires "providing three friction surfaces of the same material with different roughness and friction surfaces of different areas with the same roughness", and there are provisions on the size, flatness error and acceptable range of motor pulling speed of friction plates and friction blocks.

In recent years, Wei Chengya has reached an R&D cooperation with Tsinghua University Research Center, focusing on the innovation of digital experimental equipment, which can provide scientific physics exploration laboratory scheme configuration services for schools, help schools cultivate middle school students' scientific exploration consciousness, methods, skills, innovative spirit, thinking ability and cooperation consciousness, and further promote students' all-round development.
