Abstract

The invention discloses a charging circuit, a charging device and a capsule endoscope charging system, wherein the charging circuit includes an electric energy input terminal, a sampling control circuit, a comparison circuit, a pulse generating circuit and a power supply circuit; the electric energy input terminal is connected to the sampling control circuit in sequence and the power supply circuit; the polarity control terminal of the power supply circuit is connected to the pulse output terminal of the pulse generating circuit, and is configured to switch the charging polarity direction under the action of the pulse signal; the comparison circuit includes a first comparison branch, and the first comparison branch passes sampling The input terminal is connected to the sampling output terminal of the sampling control circuit, and connected to the limiting input terminal of the pulse generating circuit through the first comparison output terminal, and is configured to control the output electrical signal of the pulse generating circuit to be constant when the sampling electrical signal meets the first preset condition. The charging circuit provided by the invention can self-adaption polarity charging, shorten the duration of the reverse connection state, adjust the output in time, and adapt to various devices to be charged.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging circuit, a charging device and a charging system for a capsule endoscope. Background technique [0002] Batteries are widely used in various electronic devices. They can not only provide electrical energy for electronic devices to realize their functions through discharge, but also receive external electrical energy input to achieve recycling. At present, devices with batteries are usually configured for unidirectional charging. Users need to strictly distinguish the polarity direction of the device connected to the charging circuit so that it can cooperate with the charging circuit to charge normally. [0003] The prior art provides a scheme of polarity judgment and switching to solve this problem, but on the one hand, the polarity judgment process mostly adopts the scheme of configuring the electronic equipment to discharge to the charging circuit side, and the char...
