Problems solved by technology

[0002] At present, 40-ampere and 60-ampere ammeters are generally used in general houses, and even 20-ampere ammeters are used in old buildings. Separate heating (cooling) equipment is used in multiple rooms at the same time. Fire can be avoided by artificially switching some rooms, but because people cannot accurately estimate the current in each room, this operation is blind, which is neither safe nor convenient.
[0003] The existing technology does not propose a corresponding technical solution to control the operation of the terminal for the above situation, which may lead to various unsafe events caused by excessive current load

Embodiment

[0012] The maximum current allowed by the default incoming line is I=40 amperes, and the working currents of heating terminals A, B, C, D, E, F, G, H, and J are respectively I a =10, I b =13, I c =8, I d =11, I e =12, I f =13, I g =13, I h =12, I j =12 amps, ， The heating period of a day is divided into six periods, namely 5:30~8:00, 8:00~11:30, 11:30~13:30, 13:30~17:30, 17:30~21:30 , 21:30~5:30. Now take the 5:30~8:00 heating period as an example, the system setting is shown in Figure (1). When the system is working, it first determines that the current date is Tuesday, and then determines that it is currently in the 5:30~8:00 heating period and the period The priority numbers corresponding to all heating terminals in the interior are A-5, B-2, C-6, D-4, E-1, F-3, G-7, H-9, J-8, and the central processing The device sends a power-on command to the sorting No. 1 terminal E, and the central processing unit detects that the incoming bus current=I e =12 amperes b +I ...

Abstract

The invention relates to a multi-terminal heating and cooling control method based on total current control, which prioritizes all heating and cooling terminals in the same heating and cooling time period; a central processing unit sends an electrification instruction to a terminal which is prioritized in the first place; the maximum rated current of a system is assumed to be a value; the central processing unit sets an upper current limit which is more than the present current of a current detection module detection system; if the maximum rated current of the system is more than the upper current limit, the central processing unit sends the electrification instruction to the terminal which is prioritized in the first place after an electrified terminal; and the process is repeated, until the present current in the system after one terminal is electrified is more than the set current, and the central processing unit immediately sends a power-off instruction to the terminal. The multi-terminal heating and cooling control method based on total current control has the beneficial effect that: the occurrence of various unsafe events caused by too large load can be effectively avoided.

Description

technical field [0001] The invention relates to a control method for heating and heating terminals, in particular to a multi-terminal heating and cooling control method based on total current control. Background technique [0002] At present, 40-ampere and 60-ampere ammeters are generally used in general houses, and even 20-ampere ammeters are used in old buildings. Separate heating (cooling) equipment is used in multiple rooms at the same time. Fires can be avoided by artificially switching some rooms, but because people cannot accurately estimate the current size of each room, this operation is blind, which is neither safe nor convenient. [0003] The prior art does not propose a corresponding technical solution to control the operation of the terminal for the above situation, which may lead to various unsafe events caused by excessive current load. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the present invention proposes ...
