Embodiment Construction

[0033] The invention utilizes the noise generated by trains in the tunnel, and is composed of piezoelectric power generation modules and intelligent control modules arranged on both sides of the tunnel to realize the electric energy conversion of the train noise in the tunnel and the intelligent control of lighting. The present invention uses PTZ-5H as the power generation material, utilizes the piezoelectric effect of the material to convert the sound energy into electrical energy, expands it to the charging voltage through series connection, and then converts the alternating current into a stable DC electric energy through an AC / DC converter, and finally passes through The boost circuit stores electrical energy to the battery pack. The intelligent control module is composed of a sound sensor, a power sensor of the main battery pack, a single-chip microcomputer and related auxiliary equipment. The single-chip microcomputer collects the charge state information of the main bat...

Abstract

The invention discloses an intelligent train tunnel noise generating system based on single chip microcomputer control, which comprises a mounting structure and an integrated device (4) connected with the mounting structure, wherein the integrated device (4) comprises a single chip microcomputer processing unit, a noise generating unit, a piezoelectric ceramic generating module connected with the single chip microcomputer processing unit through a data line, a voltage-stabilizing energy storage module and an intelligent control module. Noise generated by the train in the tunnel is used, and through the piezoelectric generating module and the intelligent control module arranged at two sides of the tunnel, electric energy conversion by the tunnel train noise and intelligent lighting control are realized; and the recovery and the utilization of noise energy can be effectively realized, the energy is saved while the purpose of noise reduction is achieved, and the line arrangement in the tunnel is simplified.

Description

technical field [0001] The invention is a noise-reducing power generation device with piezoelectric effect and single-chip microcomputer control as the core. Its essence is a device that uses the piezoelectric effect of piezoelectric ceramics to convert the noise and vibration in the train tunnel into electrical energy and transmits it to the lighting grid through a single-chip microcomputer. Background technique [0002] The harm of noise to the human body is systemic, which can not only cause changes in the auditory system, but also affect the non-auditory system. The early stages of these effects are mainly physiological changes, and long-term exposure to relatively strong noise can cause pathological changes. In addition, the noise in the workplace can also interfere with language communication, affect work efficiency, and even cause accidents. [0003] Take the noise decibels and the train tunnel with greater impact as an example. Because the tunnel body is a relativ...
