The display that links to each other with described processor, show current information to be displayed in the described electric parameter.
Wherein, described display is liquid crystal display.
Wherein, also comprise:
At least one button that links to each other with described processor, adjust the current demonstration information of described liquid crystal display.
Wherein, described display is touch-screen display.
Wherein, also comprise:
The communication interface that connects described processor and a terminal.
Wherein, also comprise:
The storer of electric parameter that link to each other with processor, the described processor analyzing and processing of storage process.
At least a electric parameter of the current monitoring rail that the processor reception sample circuit in the monitoring of stray current device that the utility model embodiment provides gathers, and received electric parameter carried out analyzing and processing, current information to be displayed in the electric parameter is sent to display, and this display shows received current information to be displayed.As seen, compared with prior art, monitoring of stray current device provided by the utility model can accurately show by a display at least a electric parameter of institute's monitoring rail.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do simple the introduction to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of monitoring of stray current device provided by the utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
For the multiple electric parameter of while rail that Obtaining Accurate is monitored, the utility model provides a kind of monitoring of stray current device.
As shown in Figure 1, a kind of monitoring of stray current device provided by the utility model can comprise:
Gather the sample circuit 110 of at least a electric parameter of current monitoring rail;
The processor 120 of the electric parameter 110 that link to each other with sample circuit, that analyzing and processing sample circuit 110 gathers;
120 that link to each other with processor, as to show current information to be displayed in this electric parameter display 130.
In the monitoring of stray current device that present embodiment provides, processor receives at least a electric parameter that sample circuit gathers, and received electric parameter carried out analyzing and processing, current information to be displayed in the electric parameter is sent to display, and this display shows received current information to be displayed.As seen, compared with prior art, monitoring of stray current device provided by the utility model can accurately show by a display at least a electric parameter of institute's monitoring rail.
Wherein, this sample circuit can for an integrated circuit that can gather at least a electric parameter, perhaps, gather the set of the multiple sample circuit of different electric parameters.The electric parameter that sample circuit gathers can comprise at least: the rail structure voltage of rail, the corresponding polarizing voltage of rail etc.And display can directly show the electric parameter information that sample circuit gathers, and perhaps, shows the electric parameter information of processing through processor, such as: maximal value, minimum value or the mean value etc. of rail structure voltage.Certainly, display can also show the information that some are met consumers' demand under the control of processor, such as: current time, ambient temperature etc.
Be understandable that this monitoring of stray current device can be set to portable casing, to make things convenient for the staff to the monitoring of the electric parameter of different rails.
