Abstract

The invention relates to the technical field of experimental systems, and specifically relates to a multifunctional physical experimental instrument. The multifunctional physical experimental instrument comprises a projector bulb preheating protection circuit, a projector theft-proof system, a CAN bus, a luminosity adjusting system and a main control system, wherein the projector bulb preheating protection circuit is connected with a lighting system of the projector system, and is used for preventing too high impulse current and protecting a bulb; both the projector theft-proof system and the luminosity adjusting system are connected with the main control system via the CAN bus; the projector theft-proof system adopts a plurality of mercury switches and normally-closed switches, acquires the voltage change caused by circuit change by using an A / D converter inside Attiny13, and then judges whether to give an alarm; and a terminal node controller of the luminosity adjusting system receives data from a coordinator node via a CC2420 radio frequency module, and controls a relay according to the indication of the coordinator node, thus switching the states of lamp switches in a laboratory. The multifunctional physical experimental instrument realizes remote monitoring, is high in intelligence and safer, and has strong creativeness.

Description

technical field [0001] The invention relates to the technical field of experiment systems, in particular to a multifunctional physical experiment instrument. Background technique [0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. Its theoretical structure fully uses mathematics as its working language, and experiments are the sole criterion for testing the correctness of the theory. It is the most sophisticated natural science discipline today. Physics is the regular summary of people's knowledge of the transformation of matter in inanimate nature. This movement and transformation should be of two kinds. One is the extension of early people's sensory vision, and the ...
