Electronic switching unit without energy consumption for standby power supply of model airplane receiver

Abstract

The invention discloses an electronic switching unit without energy consumption for a standby power supply of a model airplane receiver. Along with the constant development and popularization of model airplane activities, amateurs who are high on large-level model airplanes become more and more, but a lot of amateurs are only equipped with the cognitive level on that airborne equipment of small-class model airplanes consumes power and usually ignore or forget the state of charge of the battery of the model airplane receiver during outfield flight, so that non-maneuvering accidents caused by the power shortage of the receiver usually occur. According to the power consumption characteristics of the model airplane receiver and a steering engine as well as the technical requirements for a battery pack, the invention solves the problem that when the model airplane receiver is short of power in the air, the standby power supply can be quickly and directly switched to for the emergency power supply of the receiver, and can effectively control airplane crash accidents caused by the power shortage of the battery pack of the model airplane receiver. The electronic switching unit is formed by that a design idea of computer online emergency power supply, which is quick in response, is borrowed, a micro-power consumption voltage detector is used as a core, a P-channel high-power field effect transistor is used as a switching actuating element for a main power supply and the standby power supply, a few discrete electronic elements are used as supplement elements, and a circuit not only has simple and direct and reliable structure, but also has no need of debugging.

Description

technical field [0001] The invention belongs to the technical field of model airplanes and electronics, and relates to a non-power consumption electronic switching device for a standby power supply of a model airplane receiver. Background technique [0002] With the continuous popularization of aviation model science and technology activities, more and more enthusiasts are keen on large-scale aviation models, such as gasoline engines. However, some aviation model enthusiasts have not paid enough attention to technical issues such as the rapid increase in power consumption of large-scale air-model steering gear and other airborne equipment, but have stayed at the level of awareness of power consumption of small-scale air-model airborne equipment. It was released to the field without conducting a full-scale simulation test on the on-board battery pack on the ground. During the uninterrupted take-off and landing flight in the field, the problem of the remaining power of the ba...
