Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of single-phase electric energy meter.
Background technology
The single-phase electric energy meter of prior art comprises microcontroller, LCD display module, memory module, RS485 communication module and electric current and voltage sampling module, and described LCD display module, memory module, RS485 communication module, electric current and voltage sampling module all are connected with microcontroller.There is following defective in the single-phase electric energy meter of said structure in the use procedure of reality: because the RS485 communication module is not supported multiple communication media, communication distance is short, node capacity is little and poor anti jamming capability, therefore must cause adopting the single-phase electric energy meter of RS485 communication module to be subject to very big impact, and then cause the functional reliability of single-phase electric energy meter poor and the scope of application is little.Therefore, for these reasons, needing to demand the high and single-phase electric energy meter applied widely of a kind of functional reliability urgently, to address the above problem.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of functional reliability high and single-phase electric energy meter applied widely.
The technical solution of the utility model is, a kind of single-phase electric energy meter is provided, comprise microcontroller, LCD display module, memory module, RS485 communication module and electric current and voltage sampling module, described LCD display module, memory module, RS485 communication module, electric current and voltage sampling module all are connected with microcontroller, described single-phase electric energy meter also comprises the LonWorks communication module, and described LonWorks communication module is connected with microcontroller.
Described microcontroller is single-chip microcomputer; The model of described single-chip microcomputer is ATT7025.
Described single-phase electric energy meter also comprises the peak-trough electricity pilot lamp, and described peak-trough electricity pilot lamp is connected with microcontroller.
After adopting above structure, the utility model compared with prior art has the following advantages:
It is main that the utility model adopts the LonWorks communication module, the RS485 communication module is auxiliary structure, because the LonWorks communication module is supported multiple communication media, communication distance is long, node capacity is large and antijamming capability is strong, therefore generally use it for long-distance transmissions, good and applied widely with the functional reliability that guarantees single-phase electric energy meter.The RS485 communication module is then used short range transmission, thereby avoids the abandoning of checkout equipment of the existing RS485 of employing communication module, has reduced to a certain extent use cost.
As improvement, described single-phase electric energy meter also comprises the peak-trough electricity pilot lamp, and described peak-trough electricity pilot lamp is connected with microcontroller, by this peak-trough electricity pilot lamp reminding user effectively, thereby is conducive to taking full advantage of of electric energy.
