Abstract
The utility model discloses a single-phase local charge-control electric energy meter comprising a main data processor, an LCD display device, an IC card connection opening, a storage device, a metering chip, a power source, and a cover-opening monitoring module, wherein the LCD display device, the IC card connection opening, the storage device, the metering chip, the power source, and the cover-opening monitoring module are connected with the main data processor. The cover-opening monitoring module comprises a cover-opening monitoring probe, a timing device, and an auxiliary processor, wherein the timing device is connected with the cover-opening monitoring probe, the auxiliary processor is connected with the timing device, and the auxiliary processor is also connected with the storage device and the power source. The single-phase local charge-control electric energy meter is advantageous in that after the cover-opening monitoring module is added and mounted, whether an electric energy meter cover is opened can be sensed, opening time can be recorded in detail and data can be stored in the storage device, monitoring workers can call out cover-opening record of the electric energy meter through instructions, and lawless persons can be prevented from refitting the electric energy meter.
Description
Technical field
The utility model relates to the single-phase local cost control electric energy meter.
Background technology
The single-phase local cost control electric energy meter is deducted fees by inserting the IC-card of having supplemented with money in advance.Existing single-phase local cost control electric energy meter all is to adopt sealing cap to carry out electric energy meter anti-Kaifeng identification, and so anti-seal opening device is relatively backward, if there is such sealing cap also to be easy to electric energy meter is juggled things in lawless person's hand.
The utility model content
The purpose of this utility model is to provide the single-phase local cost control electric energy meter, can effectively solve the problem that the anti-seal opening device of existing single-phase local cost control electric energy meter does not have illegally to open in detail record.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the single-phase local cost control electric energy meter, comprise master data processor, the LCD display that links to each other with master data processor, IC-card interface, storer, computation chip, power supply, also comprise the monitoring modular of uncapping that is connected with master data processor, the described monitoring modular of uncapping comprises the monitoring probe of uncapping, the timer that links to each other with the monitoring probe of uncapping, the auxiliary processor that links to each other with timer, and described auxiliary processor also links to each other with power supply with storer.
Preferably, also be connected with load voltage monitoring modular and load current monitoring modular on the described master data processor; The load current of monitor user ' and voltage abnormal conditions occur and can in time take power-off protection.
Preferably, also be connected with the infrared data interface on the described master data processor; Can carry out exchanges data by the infrared data interface with external unit.
Preferably, also be connected with the RS485 interface on the described master data processor; Carry out remote control by network.
Preferably, also be connected with the carrier communication interface on the described master data processor; Utilize power transmission line to carry out telecommunication, be conducive to remote meter reading, save labour cost.
Compared with prior art, the utility model has the advantages that: by installing the monitoring modular of uncapping additional, can whether open by the perception electrical-energy meter cap, and detail record time of opening, these data are stored in the storer, the monitor staff can access by instruction the record of uncapping of this electric energy meter, prevents that the lawless person from reequiping electric energy meter.
Description of drawings
Fig. 1 is the structured flowchart of the utility model single-phase local cost control electric energy meter.
Embodiment
Consult the embodiment that Fig. 1 is the utility model single-phase local cost control electric energy meter, the single-phase local cost control electric energy meter, comprise master data processor 1, the LCD display 2 that links to each other with master data processor 1, IC-card interface 3, storer 4, computation chip 5, power supply 6, also comprise the monitoring modular 7 of uncapping that is connected with master data processor 1, the described monitoring modular 7 of uncapping comprises the monitoring probe 8 of uncapping, the timer 9 that links to each other with the monitoring probe 8 of uncapping, the auxiliary processor 10 that links to each other with timer 9, described auxiliary processor 10 also links to each other with power supply 6 with storer 4, also be connected with load voltage monitoring modular 11 and load current monitoring modular 12 on the described master data processor 1, also be connected with infrared data interface 13 on the described master data processor 1, also be connected with RS485 interface 14 on the described master data processor 1, also be connected with carrier communication interface 15 on the described master data processor 1.
The monitoring probe 8 of uncapping is installed in the electric energy meter body of electrical-energy meter cap below, can be that photosensitive probe also can be the contact probe, when electrical-energy meter cap is dug, the monitoring probe 8 of uncapping starts, timer 9 begins to record the electrical-energy meter cap opening time simultaneously, to auxiliary processor 10, auxiliary processor 10 is recorded in the storer 4 after data are handled well with these data feedbacks.The testing staff just can check by instruction the opening time of this electric energy meter later on, to determine whether this table was moved trick by the lawless person.This apparatus structure is simple, has changed traditional shortcoming that installs lead sealing or the easy destroyed rear easy recovery of sealing cap additional, can effectively monitor and record the electric energy meter cover opening situation, whether this electric energy meter is unlocked plays effective monitoring.
The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
