Description

Energy saving intelligent control method for residential heating

Technical field

The invention relates to an energy-saving intelligent control method for residential heating, which belongs to the technical field of computer automatic control of heating and heating systems.

Background technique

At present, known heating temperature controllers are mainly mechanical radiator temperature control valves, which are composed of a temperature sensing element, namely a temperature bulb, a hot water flow regulating valve and a knob for adjusting temperature. Disadvantages of this temperature controller: the indoor temperature is set in a manual adjustment mode, and it is impossible for all temperature control valves to be adjusted once a day by a special person on and off work, or to turn off the heat in time when there is no one in the room for a long time, resulting in no room in some rooms. People also provide heat as usual; in most rooms, the temperature control valve knob is adjusted to the highest temperature position, which makes the indoor heating temperature too high, and even opens the windows to release heat, resulting in a great waste of energy.

Contents of the invention

In order to overcome the above-mentioned deficiencies, the object of the present invention is to provide a kind of residential heating energy-saving intelligent control method, for the house, the room temperature is controlled at the antifreeze temperature during working hours, and the room temperature is controlled at the set temperature during non-working hours; The three states of "on heat" state, "off heat" state of normal antifreeze temperature, and "off work" state of antifreeze temperature during working hours and set temperature during non-working hours can be mutually converted; use the indoor maximum temperature locking function to limit the maximum indoor temperature. Temperature; set the date and time in advance when there is no one at home for a long time during business trips and tourism, automatically turn off the heat on time, and automatically restore the original working state when returning; realize intelligent control. Utilizing the method can greatly save energy and increase comfort.

The technical solution adopted by the present invention to solve the technical problems is: in order to achieve the above object, the present invention is achieved through the following technical solutions, a single-chip computer control system, which consists of a single-chip computer unit, a voice output unit, an infrared receiving circuit, Composed of perpetual calendar unit, heating actuator, room temperature detection circuit, household infrared remote controller and special remote controller for locking temperature; I/O port connection.

Please refer to Fig. 7, Fig. 7 is holiday subroutine, judges whether the date of current perpetual calendar is " New Year's Day ", " Spring Festival ", " May 1st ", " October 1st " one of these four statutory holidays, if so then will Holiday flag position 1, used to mark the holiday "hot".

First, the system reads the perpetual calendar date and time in step 701, and then in step 702, according to the date query, the lunar calendar and the Gregorian calendar date comparison table stored in the single-chip computer unit are pre-compiled, and in step 703, it is judged whether the day is a Spring Festival holiday: Yes , then in step 704 the holiday mark position is set to 1; no, then in step 705 it is judged whether the current date is New Year’s Day: yes, then the holiday mark position is set to 1 in step 706; May 1": Yes, then set the holiday flag position to 1 in step 708; No, then determine whether the current date is "October 1" in step 709: Yes, then set the holiday flag position to 1 in step 710; No, then In step 711 the holiday flag bit is set to 0.

Please refer to Fig. 8, Fig. 8 is " turn off heat " key subroutine, at first judge whether to press " turn off heat " key in step 801: No, then return in step 805; , in step 803 will open the flag position 0, in step 804 will execute the subroutine of heat-off action, then return in step 805.

Please refer to Fig. 9, Fig. 9 is " heating " key subroutine, at first judge whether to press " heating " key in step 901: No, then return in step 905; , in step 903 will open the flag position 1, in step 904 will execute the subroutine of heating action, and then return in step 905.

Please refer to Fig. 10, Fig. 10 is " go to work " key subroutine, at first judge whether to press " go to work " key in step 1001: No, then return in step 1004; Step 1003 will turn on flag location 0, then return at step 1004.

Please refer to Fig. 11, Fig. 11 is a subroutine for locking the maximum limit temperature, which receives the locked temperature input by the special remote controller for the locked temperature and stores it in the memory. In the set temperature plus 1°C and minus 1°C subroutines, the set temperature is selected between the antifreeze temperature and the locking temperature. The lock temperature manager can adjust between +5°C and +35°C with the special remote control for lock temperature according to needs.

First in step 1101, judge whether the user presses the lock temperature key: if no, then return in step 1108; Whether the value is greater than 35: if no, save the value in step 1107; if yes, set the value to 5 in step 1105, and then save the value in step 1106.

Please refer to Fig. 12, Fig. 12 is a business trip subroutine, and the user uses the infrared remote controller to input the date of travel, time and return date, time into the single-chip computer unit, and store it in the memory. According to judging whether the current date and time are within the travel date and time and the return date and time, the heat is turned off when traveling, and the room temperature control state before returning is restored when returning. In step 1201, the system first reads the current perpetual calendar date and time, and then judges in step 1202 whether the current date and time are earlier than the date and time of the business trip: if yes, then keep the original control state unchanged in step 1203; if not, continue in step 1204 Judging whether the current date and time have passed the return date and time: yes, the control state before the business trip is restored in step 1205, and the business trip flag is set to 0 in step 1206;
