The communication transmission of the utility model cannot be restricted by the connection angle of the interface, and normal communication can be ensured all along.
Description
Technical field
The utility model relate to a kind of be used for electric energy meter and computer and (or) infrared transmission device of communicating by letter between the data Copy and reading apparatus, especially relate to be used for computer and (or) infrared transmission means of data Copy and reading apparatus end.
Background technology
In the electric energy meter industry, national standard DL/T645 has stipulated the closely communication interface of infrared transmission of a kind of employing; International standard IEC1107 also has identical regulation.This kind interface two groups of infrared receiver tubes of definition and power valve between the both sides of communication constitute the data channel of both direction in pairs and set up physical data channel.According to these standards, prior art the both sides of needs communication be electric energy meter one side and computer and (or) infrared transmission means of data Copy and reading apparatus one side employing all has only an infrared receiver and an infrared emission unit, like this communication two party especially computer and (or) position of data Copy and reading apparatus one side's infrared transmission means must be on the fixed angle of specifying circular interface, this brings greater inconvenience to operation, the restriction of position simultaneously brings communication disruption and data exception easily, can't proper communication when circular interface connection angle changes.
The utility model content
For solving exist in the prior art unreliable and cause the problem of communication abnormality easily, the purpose of this utility model be to provide a kind of can be in circular interface the infrared transmission means to realize under the situation that angle connects arbitrarily communicating by letter.
This infrared transmission means that the utility model provides, comprise infrared emission circuit and infrared receiving circuit, wherein the infrared emission circuit comprises the transmitter unit that contains a driver and a power valve, infrared receiving circuit comprises phase inverter and contains the receiving element of a receiving tube, it is characterized in that having two transmitter units in the described infrared emission circuit at least, also has an output driver, this output driver is in parallel with all transmitter units, described infrared receiving circuit has two receiving elements at least, a logical adder, all receiving elements are connected with described logical adder, and this logical adder is connected with phase inverter again.
Each transmitter unit is worked simultaneously during the utility model work, and all transmitter units are externally exported infrared signal simultaneously when sending data; Each receiving element uses logical "or" computing, as long as then export received signal when having a receiving element to receive useful signal.Therefore communications of the present utility model is not subjected to the restriction of interface connection angle, can guarantee proper communication all the time.
