Abstract
The utility model discloses a three-phase intelligent meter capable of acquiring information of power distribution and power utilization. The three-phase intelligent meter comprises a sampled signal conditioning unit, an electric energy measurement unit, a power supply module, a central processing unit, an RS485 communication unit, an infrared communication unit and an alarm output unit, wherein the signal output end of the sampled signal conditioning unit is connected with the central processing unit through the electric energy measurement unit; the central processing unit is connected with the RS485 communication unit, the infrared communication unit and the alarm output unit; the RS485 communication unit is in communication with a meter reading terminal; and the RS485 communication unit is connected with a backup power supply. The RS485 communication unit of the intelligent meter can be in communication with a connected acquisition terminal continuously under the condition that a power distribution network stops supplying power, and can report the data information of power distribution equipment before and after malfunction to the terminal through message interaction.
Description
Technical field
The utility model relates to information acquisition field, relates in particular to the three-phase intelligent table that realization is joined, power information gathers.
Background technology
At present, national grid conventional three-phase intelligent table in " power information acquisition system " just possesses conventional metering and event discrimination function, and, the in the situation that of power distribution network power-off, RS485 module cannot continue to communicate by letter with acquisition terminal because power supply disappears, thereby device fault information cannot be reported to main website, cause distribution network failure not found in time and to process.
Utility model content
The purpose of this utility model is to provide a kind of for the three-phase intelligent table of joining, power information gathers, can be to terminal to report controller switching equipment at the data message of front and back that breaks down.
The utility model adopts following technical proposals: a kind of realization joined, the three-phase intelligent table that power information gathers, include sampled signal conditioning unit, electric energy measurement unit, power module, CPU (central processing unit), RS485 communication unit, infrared communication unit and warning output unit, the signal output part of sampled signal conditioning unit connects CPU (central processing unit) by electric energy measurement unit, CPU (central processing unit) connects respectively RS485 communication unit, infrared communication unit and warning output unit, communicate by letter with meter reading terminal in RS485 unit, described RS485 unit is connected with standby power supply.
The storage unit of profile data when described CPU (central processing unit) is connected with storage failure generation.
Described CPU (central processing unit) is connected with clock unit, button/display unit.
Described CPU (central processing unit) is connected with detection of power loss unit.
The utility model proposes a kind of three-phase intelligent table; The RS485 module of this intelligent meter, in the situation that power distribution network power supply disappears, can continue and the acquisition terminal communication being connected, and by interacting message, the data message to terminal to report controller switching equipment before and after breaking down.
Brief description of the drawings
Fig. 1 is intelligent electric meter general structure block diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of realization to join, the three-phase intelligent table that power information gathers, include sampled signal conditioning unit, electric energy measurement unit, power module, CPU (central processing unit), RS485 communication unit, infrared communication unit and warning output unit, the signal output part of sampled signal conditioning unit connects CPU (central processing unit) by electric energy measurement unit, CPU (central processing unit) connects respectively RS485 communication unit, infrared communication unit and warning output unit, communicate by letter with meter reading terminal in RS485 unit, described RS485 unit is connected with standby power supply.Primary power and modular power source, standby power supply are all modules power supply by power management and conditioning unit, after communication power supply disappears, standby power supply can be still RS485 loop power supply, three-phase intelligent table still can be communicated by letter with acquisition terminal after distribution system loses power supply, and the status data in electric energy meter is reported to acquisition terminal.Wherein standby power supply can adopt battery.
The storage unit of the profile data (time on date, current/voltage instantaneous flow, electric flux) when described CPU (central processing unit) is connected with storage failure generation; Described CPU (central processing unit) is connected with clock unit, button/display unit; Described CPU (central processing unit) is connected with detection of power loss unit.CPU (central processing unit) is connected with house dog, security protection, temperature sensor, relay control unit.
