Description
Technical field
The utility model relates to smart electricity meter device field, specifically a kind of anti-high frequency stealing terminal box.
Background technology
In recent years, stealing criminal offence, except having disguise, mobility, the essential characteristic such as sudden, also presents the trend of specialization, high-technicalization, transprovincially fleeing, and investigates and prosecutes difficulty increasing.From the case investigated and prosecuted, part stealing family takes that special messenger is on duty, installing monitoring remote control equipment, obstruct power utility check personnel and enter scene, rapidly destroy the means such as the on-the-spot evidence of stealing, take precautions against, stop inspection of opposing electricity-stealing, even besiege, abuse, hit the personnel of opposing electricity-stealing, the problems such as investigation of therefore opposing electricity-stealing is difficult, evidence obtaining is difficult, process is difficult are comparatively outstanding.In a word, mainly there is following several respects problem at present:
One, time power utility check personnel arrive the inspection of suspicion user measuring apparatus, the stealing equipments such as such as high frequency remove by lawless person in advance, are difficult to find.
Even if two find the phenomenons such as table case is destroyed, owing to lacking strong evidence, lawless person does not admit that stealing is true yet, causes the present situation that process is difficult.
Three, the stealing mode such as high frequency is difficult to find due to power information acquisition system, is in the white space of monitoring at present.
In addition, some enterprises take stealing mode to reduce operating cost, illegitimately make exorbitant profits, and also destroy market fair competition principle simultaneously, compromise the interests of lawful operation person of the same trade or business; Often cause the serious problems such as power supply and power use facilities damage, large-area power-cuts and personal injury, threaten power grid security and social safety, make a very bad impression, very harmful.How efficiently and effectively carries out the Controlling line loss work of power supply enterprise, improves the management level of power supply enterprise further, is the important topic of pendulum in face of power supply enterprise.
The frequency range that intelligent electric meter is " GB/T17626.3 experiment and measuring technique radio frequency electromagnetic field immunity experiment " about the design standards of anti-Radio frequency interference (RFI) is 80MHz ~ 100MHz, and the highest laboratory strength is 10V/m.Present intelligent electric meter is all produced according to this standard design.Then, " powerful signal generator " signal intensity, up to 680V/m, is 68 times of national standard.Under strongly disturbing condition, computation chip can not normally measure.
Current intelligent electric meter all have employed intelligent metering chip, no matter is phase three-wire three, the intelligent electric meter of three-phase and four-line, or the step price ammeter of single-phase resident, is all faced with problem disturbed equally.
Utility model content
The purpose of this utility model is to provide a kind of anti-high frequency stealing terminal box, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of anti-high frequency stealing terminal box, comprise high-frequency signal acquisition module, memory module, control module and communication module, high-frequency signal acquisition module, memory module, control module and communication module are all arranged on junction box, high-frequency signal acquisition module output terminal and memory module input end are of coupled connections, gather current signal in terminal box by high-frequency signal acquisition module, and be stored in memory module; Memory module output terminal and control module input end are of coupled connections; The output terminal of control module and the input end of communication module are of coupled connections.
As further program of the utility model: communication module output terminal is connected by network with remote monitoring terminal.
As further program of the utility model: described network is Ethernet or GPRS communication network.
As further program of the utility model: the input end of control module connects clock module.
Compared with prior art, the beneficial effects of the utility model are: by the collection of high-frequency signal acquisition module is set to about 2ms/ time, frequency range is 80MHz ~ 2GMHz, thus high-frequency signal is gathered fast and accurately, when collecting signal, inform inspector by the mode of Ethernet or GPRS, prevent electricity filching behavior in time.
