Abstract
The utility model relates to the field of data remote communication of ultrasonic heat meters, and specifically relates to a structure with a remote communication circuit board and a main control board separated. The structure comprises the remote communication circuit board and the main control board which are connected by pins. Three optoelectronic couplers TL521 are installed in the connection between a core component TSS721A of the remote communication circuit board and the main control board so that the remote communication circuit board and the main control board are electrically isolated. When the circuit board is burned out because of mistaken connection of an external circuit, lightning strikes and the like, it is only necessary to replace the remote communication circuit board, which is easy to plug and pull and convenient for replacement. Thus time is saved, and costs can be effectively reduced.
Description
Technical field
The utility model relates to the data remote communication field of ultrasonic calorimeter, specifically a kind of teletransmission communicating circuit plate structure separated with master control borad.
Background technology
At present, the function of known ultrasonic calorimeter master control borad mainly comprises temperature sensor collection, flow sensor collection, data remote communication, data calculating, storage and shows, all functions are all gathered on a master control borad, data remote communication need to connect PERCOM peripheral communication circuit, at this moment can cause circuit board to produce some uncontrollable faults; Such as: PERCOM peripheral communication circuit spread of voltage, outside line live line working when connecting, exterior static or thunderbolt, all can cause certain injury to the function of circuit board.These are all fatal problem for thunderbolt and outside line misconnection high voltage, and high voltage can burn out the master control borad of whole product by the teletransmission part of product.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the utility model provides a kind of teletransmission communicating circuit plate the structure separated with master control borad, has solved data remote communication while going wrong, these problems that maintain and replace need to all be changed monoblock master control borad again.
The utility model solves the technical scheme that its technical problem adopts: a kind of teletransmission communicating circuit plate structure separated with master control borad, comprises teletransmission communicating circuit plate and master control borad; Described master control borad is comprised of temperature sensor, flow sensor, data remote communication module, data computation module, memory module and display module.
Described teletransmission communicating circuit plate is comprised of three photoelectrical coupler TL521, teletransmission communication signal regulator rectifier circuit, a teletransmission core devices TSS721A.
Between described teletransmission communicating circuit plate and master control borad, adopt the connected mode of contact pin, between the core devices TSS721A of teletransmission communicating circuit plate and the connection of main control board, three photoelectrical coupler TL521 are installed, make to have produced electrical isolation between teletransmission communicating circuit plate and main control board.
Described photoelectrical coupler is to take a kind of electricity-light-power conversion device that light is the media transmission signal of telecommunication.
Operation principle: the temperature sensor of ultrasonic calorimeter collects temperature signal, flow sensor collects flow signal, temperature signal and flow signal pass to single-chip microcomputer, single-chip microcomputer is to data analysis, process, calculate, and will process, result of calculation shows, storage and data remote communication, photoelectrical coupler is comprised of light emitting source and light-receiving device two parts, the pin of light emitting source is input, the pin of light-receiving device is output, at photoelectrical coupler input, adding signal of telecommunication VCC makes light emitting source luminous, after this illumination is mapped on the light-receiving device being packaged together, because photoelectric effect has produced photoelectric current, by light-receiving device output through drawing, so just can realize the conversion of electric light one electricity.
The beneficial effects of the utility model are, a kind of teletransmission communicating circuit plate structure separated with master control borad, between teletransmission communicating circuit plate and master control borad, use photoelectrical coupler to leave every TL521, when the external connection line of teletransmission communicating circuit plate causes circuit board to burn out because of static, outside line misconnection, thunderbolt etc., only also now that teletransmission communicating circuit plate is burnt out, main control board is unaffected, as long as change teletransmission communicating circuit plate, and easily plug, it is convenient to change, save time, can effectively reduce costs.
