Time division and temperature division controller

Abstract

The invention discloses a time division and temperature division controller. The time division and temperature division controller comprises a control chip, a DC24V switching power supply, a DC-DC conversion circuit, a touch screen, an RS232 communication circuit, two RS485 communication circuits, two linear isolation analog input circuits, an RTC real-time clock circuit, two analog input circuits and a PWM analog output circuit. The input end of the DC-DC conversion circuit is connected with the output end of the DC24V switching power supply, the DC-DC conversion circuit provides a direct current power supply, the touch screen is connected with the control chip through the RS232 communication circuit, and the two RS485 communication circuits, the two linear isolation analog input circuits, the RTC real-time clock circuit, the analog input circuits and the PWM analog output circuit are all connected with the control chip. Energy consumption is reduced while the heating effect is guaranteed.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a time-division and temperature-division controller. Background technique [0002] There are many colleges and universities that need collective heating in winter in our country, which consumes a lot of money. Some colleges and universities consume 50% of the total energy expenditure for heating every year. At present, the winter heating of colleges and universities in my country is not regulated according to the different conditions of various buildings used and the change of outdoor temperature in a day. For example, for public buildings, such as teaching buildings, office buildings, libraries, gymnasiums, laboratory buildings, etc., they are used during the day, but they are still heated at night when no one uses them; for student apartment buildings, they are used by students during the school term, but basically not during winter vacation. The use of heating is still carried out ...

AI Technical Summary

Problems solved by technology

For example, for public buildings, such as teaching buildings, office buildings, libraries, gymnasiums, laboratory buildings, etc., they are used during the day, but they are still heated at night when no one uses them; for student apartment buildings, they are used by students during the school term, but basically not during winter vacation. The use of heating is still carried out as usual; for example, the residential buildings of school staff and their families must ensure that the heating meets the standard at any time during the heating period. Causing some district heating to overheat

resulting in huge waste

In view of the different needs of these heating areas, heating heat or heating time, the existing heating methods are conveyed by the same main pipe or separated by branches, etc., which will cause problems such as uneven cold and hot, excessive heat loss, etc.
