Description
Technical field:
The utility model relates to a kind of handheld terminal of the station user identification apparatus based on ac rectifier, is widely used in the reality of low-voltage platform area user's census operations.
Background technology:
For realizing marketing fine-grained management and completing the needs of consumption reduction impairment target assessment, station user identification apparatus (business generaI investigation instrument) must be widely used in the census operations of platform district.Station user identification apparatus is the professional instrument that electric power system is used for distinguishing the separate and attribute of electric energy meter, can investigate thoroughly that where mutually user is by information such as which platform transformer, which bar circuit, power supplies, reflect the basic data data of each user under platform district truly, promote management of power use department unit-area management means.
The two-way confirmation method again that the Novel desk user identification apparatus of current use adopts pulsed current signal and power carrier signal to combine carries out the identification of platform district, when adjacent stations become altogether high pressure, altogether, altogether cable duct also can accurately test.
Station user identification apparatus comprises main frame and handheld terminal two parts, and main frame is arranged on substation transformer three-phase low-voltage side, and platform district census enumerator takes handheld terminal and carries out identification in user side.But in the process of reality generaI investigation, because most of user is positioned at old town, cabling situation is complicated, census enumerator often need enter the rather dark or pitch-dark place such as old unit, basement and carry out user's identification, identifier screen of handheld terminal cannot be seen clearly, in addition the instruments such as basis, pen, torch that carry cause operation inconvenience, and slow-down, reduces generaI investigation efficiency.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of structure simple, easy for installation, easy to carry, flexible, reduce artificial and instrument cost, improve the handheld terminal of the station user identification apparatus based on ac rectifier of generaI investigation efficiency.
The purpose of this utility model can be reached by following measure: a kind of handheld terminal of the station user identification apparatus based on ac rectifier, it comprises handheld terminal body, CPU module is provided with in handheld terminal body, CPU module connects carrier signal receiver module, pulse current generation module respectively, it is characterized in that the power supply terminal of pulse current generation module connects AC/DC power transfer module, AC/DC power transfer module connects rechargeable battery, rechargeable battery connecting luminous diode.
The utility model can produce following good effect compared with the prior art: the utility model can reduce the instrument of platform district generaI investigation entrained by field personnel, improves convenience and dirigibility; When rather dark or pitch-dark, the utility model both position census enumerator can provide illuminating effect when needed, the displaying contents of clear identification screen of handheld terminal can be helped again, improve census operations efficiency, be conducive to advancing platform district user census operations to carry out quickly and accurately.It has:
1, structure is simple, easy for installation.Rechargeable battery can be installed on the space under handheld terminal bonnet, light emitting diode be fixed on handheld terminal top.
2, easy to carry, flexible.Do not occupy redundant space, volume is little, lightweight.
3, reduce cost of labor and instrument cost, illuminance is high.Reduce census enumerator's workload, for census enumerator provides convenience; Without the need to using torch, reduce costs; Improve generaI investigation efficiency, illuminance can meet on-the-spot actual requirement.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment: preferred forms of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of handheld terminal (see Fig. 1) of the station user identification apparatus based on ac rectifier, it comprises handheld terminal body 8, CPU module 3 is provided with in handheld terminal body 8, CPU module 3 connects carrier signal receiver module 1, pulse current generation module 5 respectively, the power supply terminal 4 of pulse current generation module 5 connects AC/DC power transfer module 6, AC/DC power transfer module 6 connects rechargeable battery 7, rechargeable battery 7 connecting luminous diode 2.
The utility model installs rechargeable battery and light emitting diode additional on identifier handheld terminal, realizes illumination functions; Draw leading-out wire from the power supply terminal of handheld terminal simultaneously, changed by AC/DC power module, the emergent charging that can be used as rechargeable battery uses.
Carrier signal receiver module, reception carrier signal, and confirm according to the carrier signal received and connect the subscriber board district of handheld terminal and separate information.
Pulse current control module, by chip microcontroller, samples to the user side of circuit or end alternating voltage, generates conductivity control signal and also controls CPU module.
CPU module, adopt controllable switch element, conducting under the control of pulse current control module, sends pulsed current signal.
In terminal, CPU module sends pulsed current signal under the control of pulse current control module, then station user identification apparatus main frame to carrier signal receiver module send carrier signal, handheld terminal according to the carrier signal received determine and connect subscriber board district and separate information.
