Description
Technical field
The utility model relates to the current monitoring system in low-voltage distribution system, specifically the current monitoring hardware unit based on miniature circuit breaker.
Background technology
Low-voltage distribution system is not all monitored the electric current major part of user side at present, and user is unclear to the electricity consumption situation in each loop.The system that has individually monitoring is also to connect up in addition, and in distribution box, takies larger space, very inconvenient.
Along with the increase of power consumption equipment, improve electricity consumption reliability and the stability of household or office space distribution system, electricity consumption loop current Real-Time Monitoring is become to a lot of users' requirement.But it is not too convenient again additionally to increase in the on-the-spot installation of measuring unit and wiring.
Utility model content
The purpose of this utility model is to provide a kind of current monitoring hardware unit based on miniature circuit breaker, relies on this hardware, and those skilled in the art are as long as coordinate existing voltage, current processing software just can realize the monitoring of current monitoring.
The utility model adopts following scheme to realize: a kind of current monitoring hardware unit based on miniature circuit breaker, comprises distribution box; In described distribution box, be provided with several miniature circuit breakers for the protection of the normal operation of each loaded line; It is characterized in that: the end of incoming cables of described miniature circuit breaker is all integrated with current acquisition unit, Hall instrument transformer and RS485 communication module that described current acquisition unit is connected by main control chip and with this main control chip form; Described current acquisition unit is connected with a main control unit through quad; Electric energy metering module and human-computer interaction module that described main control unit comprises CPU and is connected with this CPU; Described electric energy metrical unit is also connected with for gathering the main primary voltage of user power utilization, the voltage of current signal, current sampling circuit; In described quad two for giving the power supply of described current acquisition unit, and other two is RS485 communication bus, communicates by letter with described CPU to realize this current acquisition unit.
In the utility model one embodiment, described CPU is also provided with overvoltage, under-voltage protecting circuit.
In the utility model one embodiment, described CPU model is STM32.
In the utility model one embodiment, described human-computer interaction module is touch control display module.
The utility model is integrated in collecting unit the end of incoming cables of miniature circuit breaker, compact conformation, and volume is little, and coordinates existing software, can realize the monitoring of user power utilization quantitative statistics and electric current.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figures 1 to 4, a kind of current monitoring hardware unit based on miniature circuit breaker, comprises distribution box; In described distribution box, be provided with several miniature circuit breakers for the protection of the normal operation of each loaded line; It is characterized in that: the end of incoming cables of described miniature circuit breaker is all integrated with current acquisition unit, Hall instrument transformer and RS485 communication module that described current acquisition unit is connected by main control chip and with this main control chip form; Described current acquisition unit is connected with a main control unit through quad; Electric energy metering module and human-computer interaction module that described main control unit comprises CPU and is connected with this CPU; Described electric energy metrical unit is also connected with for gathering the main primary voltage of user power utilization, the voltage of current signal, current sampling circuit; In described quad two for giving the power supply of described current acquisition unit, and other two is RS485 communication bus, communicates by letter with described CPU to realize this current acquisition unit.
In addition, above-mentioned main control unit also has overvoltage, under-voltage protection and electric energy metrical function, can protect user's power consumption equipment can not damage because voltage is undesired, and also has electric energy metrical function, can as clear as noonday electricity consumption.
Please continue referring to Fig. 1, in figure, can substantially be divided into: host computer, main control unit, three parts of collecting unit.Host computer can connect multiple main control units (maximum 247) below, and main control unit can connect again multiple collecting units (maximum 64) below, can form thus a huge current monitoring network; In distribution box, there are multiple miniature circuit breakers to protect each loaded line normally to move.Collecting unit is directly integrated in to miniature circuit breaker end of incoming cables, and circuit arrives miniature circuit breaker end of incoming cables again through collecting unit, between main control unit and collecting unit, adopts quad to be connected, and wherein powers to collecting unit for two, and other two is RS485 communication bus.Main control unit equally by RS485 communication bus by data upload to host computer.
It is worth emphasizing that, it is little that hardware connection of the present utility model has volume, and wiring is convenient, the features such as compact conformation, this hardware configuration has good use value, relies on this hardware, as long as at the existing software of middle control burning, just can realize current monitoring and electric quantitative statistics.What the utility model was claimed is this hardware configuration, is all the signal processing software of existing routine for software, does not require protection here.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
