Description
Technical field
The utility model relates to a kind of measurement mechanism to solar energy power generating header box terminal.
Background technology
For the large-sized photovoltaic grid-connected system, in order to improve the reliability between photovoltaic module and the inverter, the photovoltaic generation situation is monitored in real time, generally need between photovoltaic module and inverter, increase solar energy header box device.Generally be directly to gather direct current signal at present by digital technology, and calculate, and then carry out various parameters and handle, control and transmit, but owing to need the direct current branch of collection more, voltage is higher, and calculation of complex can cause the hardware configuration cost of whole data collection system higher, even the electric energy loss of some data acquisition system self is just very big, has reduced the efficient of solar energy power generating.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art and a kind of low cost that provides, the solar energy header box device of low-power consumption, and it is succinct, reliable, and can keep certainty of measurement and other additional function.
Realize that concrete technical scheme of the present utility model is:
Solar energy header box device comprises: single-chip microcomputer, current sample part, voltage sample part, open into amount importation, remote control output, externally communication port, display part, wherein voltage sample part, open into the amount importation., the remote control output, externally communication port, display part, current sample partly are divided into two groups, are connected in single-chip microcomputer.
The utility model is simple for structure, the precision height, and good reliability, low in energy consumption, cost is low, is suitable for the solar energy power generating industry and is extensive use of.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Consult accompanying drawing 1, single-chip microcomputer 1 in the utility model adopts the MSP430 single-chip microcomputer of TIX, it carries out analytical calculation to the current sample part 2 that receives, the sample information of voltage sample part 3, the signal into amount importation 4 is opened in monitoring, control remote control output 5 is supported external communication port 6 and display part 7; Current sample part 2 is divided into 2 groups, every group of sampling of being responsible for realizing 8 road direct currents; Voltage sample part 3 is responsible for the sampling of 1 road direct voltage; Open into amount importation 4 and comprise filtering, photoelectricity two isolated parts, can receive 2 way switch amount signals; Control remote control output 5 is made up of relay and drive circuit, provides remote control command to carrying out action; Externally communication port 6 is provided with 1 road RS-485 mouth; The digital demonstration of 5 LED is adopted in display part 7.
The utility model is work like this: direct current, direct voltage enters the AD of single-chip microcomputer through over-sampling, amplifier, by the calculating of single-chip microcomputer inside, draws 16 road direct currents again, the value of 1 road direct voltage, these data can realize distant place communication by external communication port 6; Single-chip microcomputer 1 is also finished monitoring switch amount signal, control remote signal, is supported the function of display part.
Though the present invention is with preferred embodiment openly as above, they are not to be used for limiting the present invention, anyly have the knack of this skill person, without departing from the spirit and scope of the invention, and certainly when can doing various variations or retouching, but equally within protection scope of the present invention.What therefore protection scope of the present invention should be defined with the application's claim protection range is as the criterion.
