A smart car parking control system and method based on copper wire melting

Abstract

An intelligent car parking control system and method based on copper wire melting and breaking belong to the technical fields of physical chemistry and intelligent control. The system includes a copper wire reaction module, a potential detection module, a single-chip microcomputer, a control module, a motor, and a power supply module; the copper wire reaction module includes a reaction circuit and a reaction vessel containing a ferric chloride solution; the reaction circuit includes a plurality of parallel branches, Each branch is connected with copper wire in series; the part of the copper wire to be dissolved is immersed in ferric chloride solution; the potential detection module detects the port potential of the reaction circuit, and sends the electrical signal to the single-chip microcomputer and the control module in turn, and the control module outputs the output The PWM signal controls the motor to rotate when the copper wire is not broken and to stop when the copper wire is broken. The method is implemented based on the above system. The invention makes the intelligent trolley stop automatically after traveling a predetermined distance, achieves the purpose of accurately delivering articles, is less restricted by external environmental conditions, and has practical application value.

Description

technical field [0001] The invention relates to the technical fields of physical chemistry and intelligent control, in particular to an intelligent trolley parking control system and method based on copper wire melting. Background technique [0002] The current parking control system often relies on the GPS system to realize remote parking, which cannot be realized normally in the scene of weak GPS signal. In the field of smart cars based on chemical reaction timing, most teams use the parking control system based on the iodine clock reaction, which uses a photosensitive sensor to convert the optical signal of the iodine clock reaction into an electrical signal and delivers it to the single-chip microcomputer, which is compiled and processed by the single-chip microcomputer to output another An electrical signal is sent to the control module, and the control module then outputs a PWM signal to control the rotation of the motor based on the electrical signal. However, the pa...
