Controller of ultra-low power consumption infrared sensor trash bin

Abstract

The invention provides a controller of an ultra-low power consumption infrared sensor trash bin, comprising a single chip, wherein, the single chip is respectively connected with an infrared sensing circuit and a power supply; the infrared sensing circuit comprises an infrared transmission circuit and an infrared receiving circuit; the infrared receiving circuit is composed of a receiving tube, a first-grade amplifier circuit, a second-grade amplifier circuit, a wave shaping circuit, a wave phase-inverter circuit and a receiving circuit power supply connected sequentially; the output end of the wave phase-inverter circuit is connected with the single chip, the receiving circuit power supply is connected with the single chip, and one output end of the single chip is connected with a motor. On one side, in the invention, the antijamming capability of the control circuit is enhanced; on the other side, the controller utilizes fragmented components to form the infrared receiving circuit, and the receiving circuit utilizes pulse to supply power, so only the power supply of the infrared receiving circuit needs to be started during work; single pulse signals are transmitted by the transmission circuit, thereby greatly reducing the work time of the transmission circuit and the receiving circuit, and simultaneously greatly reducing power consumption of the circuit.

Description

technical field [0001] The invention belongs to the technical field of infrared induction controllers, and in particular relates to an ultra-low power consumption infrared induction trash can controller. Background technique [0002] At present, the structure of the existing dustbin used is that the upper port of the dustbin is equipped with a cover that is movable and pivotally connected, and what has is also equipped with a mechanism for stepping on and off the dustbin lid. Its shortcoming is that when people dump rubbish in the trash can, they all open the lid manually or with their feet. When the rubbish is dumped, the lid will be closed by stepping on it with hands or feet, which brings inconvenience to the user, and the more important thing is that there is a hidden danger of hygienic infection. Later, people designed an infrared induction trash can. The infrared induction trash can controller is the core component of the infrared induction trash can, and the infrared...

Problems solved by technology

Its shortcoming is that when people dump rubbish in the trash can, they all open the lid manually or with their feet. When the garbage is dumped, the lid must be closed by stepping on it with hands or feet, which brings inconvenience to the user, and more importantly, there is a hidden danger of sanitary infection

Later, people designed an infrared induction trash can. The infrared induction trash can controller is the core component of the infrared induction trash can, and the infrared receiving circuit is the core part of the infrared induction trash can controller. The disadvantage is: because most of them use integrated infrared receivers, the power consumption is relatively large, and 4 new AA batteries can only be used for 3 months

In addition, some discrete components are used. Due to the failure to deal with the problem of analog distortion or the wrong selection of components, the sensing distance is too close, or it is disturbed under strong light. Therefore, it is necessary to improve the existing trash can controller.
