Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of large user's ammeter long-distance management device that is used for, comprise power module 1, acquiring electric energy information unit 2, meter reading unit 3, remote transmission unit 4, LCD 5, infrared communication module 6 and main control module 7, described power module 1 is connected with acquiring electric energy information unit 2, meter reading unit 3, remote transmission unit 4, LCD 5, infrared communication module 6, main control module 7 respectively, and described main control module 7 is connected with acquiring electric energy information unit 2, meter reading unit 3, remote transmission unit 4, LCD 5, infrared communication module 6 respectively.
Power module 1 is made up of devices such as three single transformers, DC-DC electric energy chip and resistance, electric capacity, inductance, can compatible phase three-wire three and the mode of connection of three-phase and four-line, under the three-phase and four-line pattern, support single phase power supply and heterogeneous power supply, under the phase three-wire three pattern, need only any two-phase and insert power module, power module gets final product the required level of normal output services, and feed system uses.
Acquiring electric energy information unit 2 is changed to the small-signal that the energy computation chip of can powering is gathered by sample circuits such as current transformer and voltage transformer (VT) with electric current and voltage signal dress, thereby electric energy computation chip is by measuring the true electrical energy parameter of inferring in the electrical network to the small-signal after the conversion.
What LCD 5 adopted is the wide short in size liquid crystal of high temperature, can realize the convenient inquiry of local data, guarantees the stable operation in rugged surroundings.Liquid Crystal Module is used for the various information in the local search terminal, convenient on-the-spot inquiry maintenance.
Main control module 7 is by a MCU, and external FLASH chip and eeprom chip adopt Rx8025 that system clock is provided, and are responsible for each task module of scheduling, realizes the storage of data and reads, and realizes the allomeric function of terminal.
This terminal has realized the long-range copy reading of large user's ammeter and management have automatically been realized the real-time monitoring to the distribution scene, has helped improving the automaticity of electrical power trans mission/distribution system.
