The household electricity supervising device
The utility model relates to a kind of Monitor for electricity use, especially a kind of household electricity supervising device.
At present, because electric energy meter can only show the total electricity consumption of each household, and can not show the electricity consumption situation (as voltage, electric current, power, power factor etc.) of each time period of household electrical appliance respectively, can't reasonably make overall planning for household electricity definite data are provided, cause family's rational utilization of electricity planning to have no way of carrying out, be created in power consumption in the period excessively and cause the situation of line impairment to take place, can not effectively utilize electric energy; On the other hand,, check also inconvenience, provide foundation so existing ammeter can only be collected the electricity charge for power supply department, and can't really provide the electricity consumption data for the user because ammeter is installed in the ammeter box usually.
Summary of the invention
The purpose of this utility model is that provide for the deficiency that solves above-mentioned technology a kind of can timesharing show each time period electricity consumption situation of household electrical appliance, and definite data are provided, and checks household electricity supervising device easily.
In order to achieve the above object, the household electricity supervising device that the utility model is designed, it mainly comprises host computer, also comprise the voltage detection unit and the current detecting unit that are used to detect the Household Appliance situation, described voltage detection unit and current detecting unit signal input to corresponding power information harvester, and this power information harvester and described host computer communicate to connect.The power information harvester can be by various microcomputerized control such as single-chip microcomputers, and integrated energy data computing function, can calculate other power consumption parameter according to voltage signal and current signal, and this function also can be integrated on the host computer.Described communicating to connect is meant the exchange of finishing mutual data between power information harvester and the host computer by existing communication mode, communication protocol, and this communication technology is a routine techniques at communication, electronic applications, do not add tired stating at this.The power information harvester can send to host computer with the detection information of voltage, current detecting unit signal, human interface software by host computer shows or data storage, wherein host computer can be a computer, also can be other man-machine interface screen HMI, show and do data storage processing to be electric field routine techniques by human interface software (as Siemens WINCC software), do not doing tired stating a bit.
In order to make layout more convenient, structure is more simple, preferred scheme is that described power information harvester is connected with the first wireless communication unit signal, described host computer is connected with the second wireless communication unit signal that matches, and described power information harvester communicates to connect by first wireless communication unit and second wireless communication unit and host computer.Can be two wireless communication units as total transceiver, and supporting first wireless communication unit separately of each household electrical appliance.
For more compact, preferred scheme is that described voltage detection unit, current detecting unit, power information harvester and the first wireless communication unit signal link into an integrated entity, thus can be conveniently to household electrical appliance configuration pick-up unit separately.
The household electricity supervising device that the utility model obtains, can timesharing show each time period electricity consumption situation of household electrical appliance, and definite data can be provided, thus be convenient for people to overall planning to household electricity, make household electricity more reasonable, when producing big electric current, can arrange the part household electrical appliance in the work of other times section, reduce line loss, some inessential electrical equipment then can quit work, save electricity consumption more, the electricity consumption of this device shows more convenient in addition.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1 shunting plate body;
Among the figure: host computer 1, voltage detection unit 2, current detecting unit 3, power information harvester 4, first wireless communication unit 5, second wireless communication unit 6.
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the described household electricity supervising device of present embodiment, it mainly comprises host computer 1, also comprise the voltage detection unit 2 and the current detecting unit 3 that are used to detect the Household Appliance situation, voltage detection unit 2 and current detecting unit 3 signals input to corresponding power information harvester 4, power information harvester 4 integrated energy data computing functions can calculate other power consumption parameter according to voltage signal and current signal.Power information harvester 4 is connected with first wireless communication unit, 5 signals, host computer 1 is connected with second wireless communication unit, 6 signals that match, power information harvester 4 communicates to connect with host computer 1 by first wireless communication unit 5 and second wireless communication unit 6, and its communication mode is the RF wireless transmission method.Wherein: described voltage detection unit 2 is the mutual voltage detecting device, described current detecting unit 3 is a manganese copper diverter, detection mode to electric current, voltage in the prior art is varied, present embodiment also can adopt other checkout equipment voltages, electric current to detect, and does not add tired stating at this.
During use, voltage detection unit 2 and current detecting unit 3 with the voltage and current signal conveys of household electrical appliance to power information harvester 4, this power information harvester 4 is by computing, draw data such as power, power factor, and send the data to host computer 1 by communication, host computer 1 is given the user with these data presentation, performs simultaneously to store backup, inquires about at any time being used for.
This family Monitor for electricity use can timesharing show each time period electricity consumption situation of household electrical appliance, and definite data can be provided, thereby is convenient for people to the overall planning to household electricity.
