Abstract
The utility model discloses an SCM controller for displaying the auxiliary temperature of an electric water heater on a train, which belongs to the SCM technology applied to the control field of the electric appliance. The utility model comprises a temperature controller, an SCM, an executive circuit of a switch tube and a display screen. The utility model is characterized in that the temperature controller is connected with the I/O input end of the SCM, and the I/O output end of the SCM is connected with the executive circuit of the switch tube and the display screen. The utility model transfers water temperature in the electric water heater through a time-base integrated circuit, and the display screen is driven by the SCM for displaying the current water temperature. The power supply of electrically heating heater is cut off when water comes to the boil. The utility model is good for the water temperature observation for the water temperature in the electric water heater and controls the drinking time to avoid the waste of electric resources when water comes to the boil and is continuously heated. The utility model is suitable for electric water heaters without temperature display on trains.
Description
Technical field the invention belongs to singlechip technology in the electrical equipment control Application for Field.
Before background technology the invention applying date, the train electric heating water heater cuts off the function of electric heating warming device power supply when not having the Current Temperatures demonstration and reaching boiling point, current water temperature of passenger observation and the time of drinking are made troubles, uninterruptedly heat simultaneously and cause the waste of electric resources.
The purpose of summary of the invention the invention provides the attached temperature display monolithic processor control device of a kind of train electric heating water heater.
The invention solves the technical scheme that its technical matters adopts: comprise temperature controller, single-chip microcomputer and switching tube executive circuit display screen; Temperature controller is connected with the single-chip processor i/o input end, and the single-chip processor i/o output terminal is connected with switching tube executive circuit and display screen.Temperature controller is made up of temperature sensor and time-base integrated circuit, and the input end of temperature sensor is connected with the input end of time-base integrated circuit, and the output terminal of time base circuit is connected with monolithic I/O input end.The single-chip processor i/o output terminal is connected with the switching tube executive circuit, and the switching tube executive circuit comprises switching tube and relay, and the normally opened contact of relay is connected with electric heating warming device power supply.
The beneficial effect of the invention is: the invention is installed on the temperature sensor in the train electric heating water heater, by the water temperature of time-base integrated circuit in single-chip microcomputer transmission electric heating water heater, by the Micro Controller Unit (MCU) driving display screen, show current water temperature, and when reaching boiling point, cut off electric heating warming device power supply.The invention helps the water temperature in the electric heating water heater is observed; The electric resources waste that grasp is drunk the time and avoided uninterruptedly heating when reaching boiling point and cause is applicable to the train electric heating water heater that no temperature shows.
Appended drawings 1 is the embodiment schematic diagram of the invention.
Embodiment is consulted accompanying drawing 1.The invention single-chip microcomputer uses PIC16C54.Temperature controller is made up of temperature sensor LM135, time-base integrated circuit 7555 and peripheral circuit.The input end of temperature sensor is connected with the input end of time-base integrated circuit 7555, and the output terminal of time-base integrated circuit 7555 is connected with single-chip processor i/o input end I/O (1), I/O (2) respectively.Single-chip processor i/o output terminal I/O (5), I/O (6), I/O (7), I/O (8), I/O (9), I/O (10) are connected with the input end of display screen respectively.Present embodiment is the LCD LCDs.Single-chip processor i/o output terminal I/O (11), I/O (12) and switching tube G
