Problems solved by technology

[0002] In the past, in middle school laboratories, separate experimental instruments were used for experiments. To measure one kind of data, it was necessary to change another kind of instrument.
At present (in the prior art), a digital experiment system has appeared in the laboratory, but it has low measurement precision, complicated man-machine exchange, does not have portable offline test function, or the operation time is short when offline, and storage Low volume and less computer interface, inconvenient measurement and other issues

Abstract

This invention relates to one intelligent experiment system, which comprises display screen, computer, bus power, bus controller on the control circuit, two power modules, USB interface on the bus controller, memory, I2C bus and intelligent sensor through multi-core terminal and I2C bus, wherein, the bus controller collects data from sensor to process data and to display the test signals through screen for storage for output through USB.

Description

technical field [0001] The invention relates to an intelligent digital experiment system, which is suitable for measuring various signal data, including: a test system for current, voltage, air pressure, force, magnetic field, temperature and light intensity. Background technique [0002] In the past, in middle school laboratories, separate experimental instruments were used for experiments. To measure one kind of data, it was necessary to change another kind of instrument. At present (in the prior art), a digital experiment system has appeared in the laboratory, but it has low measurement precision, complicated man-machine exchange, does not have portable offline test function, or the operation time is short when offline, and storage Low volume and less computer interface, inconvenient measurement and other issues. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent digital experiment system, which can overcome the problem...
