Description
Technical field
The utility model relates to a kind of supervisory control of substation technical field, particularly a kind of transformer station's voice monitoring device based on power line carrier, PLC.
Background technology
Transformer station is an important part of electric system, and therefore, the maintenance of contrast transformer station is all generally that assistant director safeguards, and needs authentication.But, in the operation of existing transformer station, still existing amateur staff enters, or professional carries out nonstandard operation after operation is discussed in the inside, although it has video monitoring, but to the generation of accident, still there is blind area in imputation, the evidence obtaining of responsibility, therefore, provides a kind of the comprehensive sound monitoring of transformer station is necessary.
Utility model content
The utility model can be realized transformer station is carried out to omnibearing voice monitoring, for managerial personnel provide monitoring foundation.
The utility model is realized by the following technical solutions: a kind of transformer station's voice monitoring device based on power line carrier, PLC, is characterized in that: comprise that several are arranged at voice acquisition module and a main frame on power transformation box; Described voice acquisition module comprises the pickup circuit, noise filtering circuit, A/D change-over circuit and the ZigBee wireless transmitter module that connect successively; Described main frame comprise one with the ZigBee wireless receiving module of described ZigBee wireless receiving module communication, the output terminal of described ZigBee wireless receiving module is connected with CPU, described CPU is connected with SD draw-in groove circuit and a power carrier communication circuit.
In the utility model one embodiment, described main frame is arranged in a power transformation box, and it is that described main frame is powered by the civil power in this power transformation box through decompression voltage regulator.
In the utility model one embodiment, described CPU is also connected with a key circuit.
The utility model utilizes ZigBee wireless module transmitting audio data, utilizes power line carrier, PLC module to carry out remote data transmission, and circuit structure is simple, need to not connect up at substation secondary, layouts by multi-faceted, realizes and gathers non-blind area.
Brief description of the drawings
Fig. 1 is the utility model embodiment schematic block circuit diagram.
Fig. 2 is the utility model voice acquisition module circuit theory diagrams.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As depicted in figs. 1 and 2, a kind of transformer station's voice monitoring device based on power line carrier, PLC, is characterized in that: comprise that several are arranged at voice acquisition module and a main frame on power transformation box; Described voice acquisition module comprises the pickup circuit, noise filtering circuit, A/D change-over circuit and the ZigBee wireless transmitter module that connect successively; Described main frame comprise one with the ZigBee wireless receiving module of described ZigBee wireless receiving module communication, the output terminal of described ZigBee wireless receiving module is connected with CPU, described CPU is connected with SD draw-in groove circuit and a power carrier communication circuit.The output transmittability that the utility model relies on ZigBee wireless module and power carrier communication circuit to possess, by the transmitting voice signal of transformer station's multipoint acquisition to remote control center, not only simple in structure, avoid in transformer station secondary wiring, and this speech data can provide foundation for the situation that supvr monitors transformer station.
Preferably, in the present embodiment, described main frame is arranged in a power transformation box, and it is that described main frame is powered by the civil power in this power transformation box through decompression voltage regulator.Main frame is arranged in power transformation box, can not only avoid main frame to be destroyed by people, and can directly utilize the power supply of power transformation box and line of electric force to carry out communication.
For better control, in the utility model one embodiment, described CPU is also connected with a key circuit.By this key circuit, user can carry out man-machine interaction.
What deserves to be explained is, ZigBee wireless module and power carrier communication circuit that the utility model adopts are all the hardware with data-transformation facility, and what the utility model was protected is hardware configuration.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
