Abstract

The invention discloses an optocoupler relay-based dual-battery seamless switching power supply realization method, and relates to the technical field of wireless equipment power supply. A power supply access of a solar battery and a power supply access of a lithium battery are connected to a normally open contact pin and a normally closed contact pin of the optocoupler relay respectively to be used as an input end and an output end to supply power for the equipment; based on the quick switching characteristic of the optocoupler relay and through voltage change at the control end, seamless switching of the solar battery power supply and the lithium battery power supply is realized; meanwhile, by virtue of matching of a lithium battery charging circuit, the solar battery supplies power forthe equipment and charges the lithium battery in a sufficient illumination condition; and at night or in a cloudy day, the lithium battery supplies power for the equipment, thereby ensuring long-termand reliable operation of the equipment.

Description

technical field [0001] The invention discloses a method for realizing seamless switching power supply of batteries, relates to the technical field of power supply for wireless devices, and in particular relates to a method for realizing seamless switching power supply of dual batteries based on optocoupler relays. Background technique [0002] Nowadays, more and more wireless devices are used in various industries for data collection and transmission. Most of these devices use manual battery replacement or solar battery power supply. However, the artificial method not only increases the cost, but also reduces the efficiency of monitoring. Even if solar cells are used, the power supply of solar cells is likely to be insufficient when the illumination time is short or the intensity is insufficient. The present invention provides a method for realizing the seamless switching power supply of dual batteries based on optocoupler relays. The input terminal and the output terminal ...
