Aiming at the energy and endurance issues of real-time status monitoring of package transportation, this paper designs a self-powered logistics environment monitoring system. an electromagnetic vibration energy harvester and energy management circuit are designed and a physical and mathematical model of the energy harvester is established by analyzing the vibration distribution of road transport vehicles; through simulation and experiment, the model of the collector proposed in this paper is compared with the measured output results, and the performance of the energy management circuit and the corresponding impedance matching analysis are tested. The simulation results of the collector are basically consistent with the measured results, and the peak value of the output voltage is higher than 1 V. The energy management circuit proposed in the article can effectively complete the boost and rectification of the collector output voltage, and the charging efficiency can reach up to 51.1% when combined with the collector. the output effect is the best when the impedance matching is 1 kΩ. The mathematical model proposed in the article is effective and reliable, and the self-powered logistics environment monitoring system program effectively improves the feasibility of improving the endurance of real-time package monitoring.
