Description
Technical field
The utility model relates to a kind of temperature control system, especially relates to a kind of central temperature controller system based on the electric current overall control.
Background technology
At present general dwelling house generally adopts 40 amperes and 60 ampere demand meters even use the situation of 20 ampere demand meters in addition in outdated building, use separately (refrigeration) equipment that heats simultaneously in a plurality of rooms because not enough frequent tripping operation even the overheated fire that causes of circuit of occurring of electric current total amount, heat (refrigeration) though equipment can be avoided by switch sections room artificially, but it is, both dangerous also inconvenient because the people can't estimate exactly that the size of current in each room makes that the blindness of this operation is bigger.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to propose a kind of central temperature controller system based on the electric current overall control.
A kind of central temperature controller system based on the electric current overall control, comprise central processing unit and a plurality of terminal control unit, establish a connection between terminal control unit and the central processing unit, be used for transfer control signal and data, this annexation can be that wired connection also can be wireless connections.Wherein central processing unit comprises current comparing module, and current comparing module is used for the comparison system electric current and whether surpasses current limit.Also comprise current detection module, the system power that is produced when being used to detect each terminal operating, and feed back to current comparing module.Also comprise terminal ordering and execution module, be used to set same terminal in the different periods the running priority order and according to electric current overall control principle according to the same period in each terminal priority carry out operation.
Its principle of work is that one day is divided into some heat supplies (refrigeration) period, and in the period whole heat supplies (refrigeration) terminal is carried out priority ordering in same heat supply (refrigeration), when arbitrary terminal of switching on is cut off the power supply because of having reached design temperature all to the central processing unit feedback information, central processing unit is promptly to just sending electrical instruction in the terminal of heat supply terminal priority ordering first afterwards before this, and detection house lead in total current, if detected electric current is less than the program default value, then central processing unit promptly after ordering is in the energising terminal terminal of priority ordering first send electrical instruction, so repeatedly when opening a terminal detected electric current greater than the current value of program setting, and no longer send electrical instruction to this terminal, to guarantee to register one's residence the current value of bus current less than program setting.Otherwise, send information to central processing unit when being reduced to design temperature under arbitrary terminal Yin Wendu and switching on, central processing unit detects the house lead in total current, if detected electric current is greater than the program default value, then central processing unit is in the terminal that end position switching on to ordering and sends cut-offing instruction, so repeatedly up to the detected house lead in total current of central processing unit less than programmed values.
The arbitrary terminal of system all can change design temperature at any time arbitrarily and close fully.
The beneficial effects of the utility model are can avoid automatically loading the excessive various dangerous incident that causes.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
A kind of central temperature controller system based on the electric current overall control, comprise central processing unit and a plurality of terminal control unit, establish a connection between terminal control unit and the central processing unit, be used for transfer control signal and data, this annexation can be that wired connection also can be wireless connections.
Its principle of work is that one day is divided into some heat supplies (refrigeration) period, and in the period whole heat supplies (refrigeration) terminal is carried out priority ordering in same heat supply (refrigeration), when arbitrary terminal of switching on is cut off the power supply because of having reached design temperature all to the central processing unit feedback information, central processing unit is promptly to just sending electrical instruction in the terminal of heat supply terminal priority ordering first afterwards, and detection house lead in total current, if detected electric current is less than the program default value, then central processing unit promptly is in the terminal that comprises the priority ordering first after interior energising terminal of firm energising terminal to ordering and sends electrical instruction, so repeatedly when opening a terminal detected electric current greater than the current value of program setting, send cut-offing instruction to this terminal immediately, to guarantee to register one's residence the current value of bus current less than program setting.Otherwise, when switching on, design temperature sends information owing to being reduced under arbitrary terminal Yin Wendu of ordering before position, the end ordering terminal of powering to central processing unit, central processing unit detects the house lead in total current, if detected electric current is greater than the program default value, then central processing unit is in the terminal that end position switching on to ordering and sends cut-offing instruction, so repeatedly up to the detected house lead in total current of central processing unit less than programmed values.
The arbitrary terminal of system all can change design temperature at any time arbitrarily and close fully.
