Abstract
The utility model discloses an optical communication data acquisition module, including a power supply unit, a main control unit, a plurality of AD conversion units, an electro-optic conversion unit, an optic digital signal output unit and a synchronous pulse demodulation unit. A control end of each AD conversion unit is connected with the main control unit. By receiving external synchronous acquisition pulses with the synchronous pulse demodulation unit, the optical communication data acquisition module can control the AD conversion units to perform synchronous acquisition under a strict clock synchronous condition, and plural acquired electric power data are good in synchronism and high in accuracy; and the electric power data after collection are subjected to electro-optic conversion and then transmitted at a fast transmission speed while an excellent synchronous effect of the data after transmission is maintained.
Description
Technical field
The utility model relates to the data acquisition technology field, is specially a kind of optical communication data acquisition module.
Background technology
In order to ensure better the normal reliable work of electric system, in electric system, generally need the various electric quantity collectors of configuration detect in real time and gather various piece.In the electric quantity acquisition process, to solve electric quantity data how synchronous, collect and the problem such as transmission, and meet the requirement of DL/T 860.5.The technical scheme that existing technology adopts is various, but all can not solve in good condition above-mentioned whole issue.
Summary of the invention
For the problems referred to above, the utility model provides a kind of all-in-one-piece optical communication data acquisition module, this module can solve in good condition electric quantity data synchronous acquisition, converge and transmission problem.
The utility model is that the technical scheme that its technical matters of solution adopts is:
The optical communication data acquisition module comprises: for the power supply unit of power supply; Main control unit; For several AD conversion unit that receive the analog acquisition signal and change, the control end of AD conversion unit is connected with main control unit; Electrooptic switching element, the input end of electrooptic switching element is connected with the output terminal of AD conversion unit, and control end is connected with main control unit; Light digital signal output unit, the input end of light digital signal output unit is connected with electrooptic switching element; For the synchronizing pulse demodulating unit that receives the external sync acquisition pulse and carry out demodulation, the output terminal of synchronizing pulse demodulating unit is connected with main control unit.
The beneficial effects of the utility model are: receive the external sync acquisition pulse by the synchronizing pulse demodulating unit, the utility model can be controlled AD conversion unit and carry out synchronous acquisition under strict clock synchronous implementations, a plurality of electric quantity data synchronisms that gather are good, and accuracy is high; Electric quantity data after collecting transmits after by electric light, changing again, and transmission speed is fast, also can keep splendid synchronous effect after transmission.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, be further detailed:
Fig. 1 is the block diagram of system of the present utility model.
Embodiment
With reference to Fig. 1, optical communication data acquisition module of the present utility model comprises power supply unit 1, main control unit 2, a plurality of AD conversion unit 3, electrooptic switching element 4, light digital signal output unit 5, synchronizing pulse demodulating unit 6.Above-mentioned unit can both utilize various relevant components and parts of the prior art and circuit to realize, does not repeat them here.
AD conversion unit 3 is be used to receiving the analog acquisition signal and changing, and the analog acquisition signal received generally comprises magnitude of voltage and current value etc., and AD conversion unit 3 carries out magnitude of voltage and current value to export after respective handling and conversion.The process of processing and changing is subjected to the control of main control unit 2.In specific embodiment, the quantity of AD conversion unit 3 can arrange as required.
The input end of electrooptic switching element 4 is connected with the output terminal of AD conversion unit 3, is converted to light signal for the electric signal by AD conversion unit 3.The process of conversion is subjected to the control of main control unit 2.
The input end of light digital signal output unit 5 is connected with the output terminal of electrooptic switching element 4, exports to outside for the light signal that electrooptic switching element 4 is converted to.During concrete application, the utility model generally coordinates merge cells to use, and therefore, this light digital signal output unit 5 generally is connected with merge cells, by optical signal transmission in merge cells.
Synchronizing pulse demodulating unit 6 is be used to receiving the external sync acquisition pulse and carrying out demodulation.The utility model is controlled the electric quantity data synchronous acquisition work of AD conversion unit 3 under this strict clock synchronous implementations.
Embodiment of the present utility model is not restricted to the described embodiments, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
