Vehicle-mounted water dispenser control system based on single-chip microcomputer

Abstract

The invention discloses a vehicle-mounted water dispenser control system based on a single-chip microcomputer, and the system comprises the single-chip microcomputer which is connected with a power line. The vehicle-mounted water dispenser control system further comprises a temperature sensor, a relay, an alarm, a keyboard and a water level monitoring circuit. The single-chip microcomputer is in circuit connection with a temperature sensor arranged in the water tank through a temperature acquisition circuit, is in circuit connection with a relay through a relay control circuit, is in circuit connection with an alarm through an alarm circuit, is connected with a keyboard through a pin, and is in circuit connection with a water level monitoring circuit through a pin. According to the vehicle-mounted water dispenser control system, the voltage stabilizing circuit is adopted for carrying out voltage stabilizing operation on the vehicle-mounted storage battery, it is guaranteed that the VCCend for supplying power to the control system has stable voltage, and therefore the situation that the control system of the vehicle-mounted water dispenser frequently breaks down due to the fact that the voltage is unstable is avoided.

Description

technical field [0001] The invention relates to the field of water dispensers, in particular to a control system for a vehicle-mounted water dispenser based on a single-chip microcomputer. Background technique [0002] In the prior art, the current of the vehicle-mounted water dispenser is not stable enough, which easily leads to the failure of the control circuit of the vehicle-mounted water dispenser, and the water temperature of the vehicle-mounted water dispenser is usually heated to 100 degrees and then stops heating. Make people can't drink the hot water in the water dispenser when they are in urgent need of drinking water, which brings great inconvenience to people's life. Contents of the invention [0003] The purpose of the present invention is to address the above problems and provide a single-chip microcomputer-based vehicle water dispenser control system that is simple in structure and easy to use. [0004] In order to achieve the above object, technical schem...
