Description
Technical field
The present invention relates to field of electrical equipment, more particularly to a kind of anti-electricity-theft intelligent electric meter.
Background technology
Currently, status of the anti-theft electricity technology of electronic electric energy meter in electric energy meter industry is more and more important, country variant,
The electric energy meter market in area all requires the electricity stealing preventive metering of electric energy meter to varying degrees.In order to reduce the loss of national wealth,
Prevent the generation of electricity stealing, power supply department makes criminal not connect using electric energy meter is placed in anti-theft electricity meter box
The mode of electric energy meter is contacted, but this antitheft mode can only prevent the mesh of electricity filching person stealing on the circuit of electric energy meter
, and electricity filching person can not be prevented and carry out stealing using other means.
Remote control is realized by the magnetic latching relay installed in ammeter to the power on/off of user at present, that is to say, that use
Family arrearage is to disconnect relay by remote signal, if under the interference of outer high-intensity magnetic field (such as Nd-Fe-B permanent magnet, magnet
Deng) can break not open relay, that is it is the electricity that do not break in the case of arrearage, terminal shows that arrearage powers off, but uses
Family is still in electricity consumption.That is stealing electricity phenomenon progressively high-technicalization, high frequency, Gao Ci, high pressure tactics interference electrical equipment are often utilized
The operation of element, the tradition means of opposing electricity-stealing can not effectively prevent this stealing electricity phenomenon.
The content of the invention
It is an object of the invention to：Solve the problems, such as that existing intelligent electric meter can not power off under high-intensity magnetic field, there is provided a kind of
Anti-electricity-theft intelligent electric meter.
The technical solution adopted by the present invention is as follows：
A kind of anti-electricity-theft intelligent electric meter, including it is MCU, AC/DC module, DC/DC modules, clock module, metering module, aobvious
Show module, current sample module and voltage sample module, it is characterised in that：Also include communication module, the ESAM moulds being connected with MCU
Block, alarm module, magnetic latching relay, Magnetic Sensor and light coupling relay, the magnetic latching relay and light coupling relay
Output is series at externally fed circuit.
In order to reduce influence of the temperature to electronic component i.e. temperature drift, further, the intelligent electric meter also includes temperature
Sensor and radiator.
In order to prevent that further, the ESAM security modules enter line number to intelligent electric meter using aes algorithm by malicious intrusions
According to encryption and decryption.
In order to ensure the intelligent electric meter energy wireless telecommunication, further, the communication module is GPRS communication moulds
Block or NB-IoT communication modules.
Preferably, the communication module uses DL/T645-2007 communication protocols.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. under high-intensity magnetic field, intelligent electric meter also can normal power down；
2. reducing influence of the temperature to electronic component, the measurement accuracy of ammeter is improved；
3.ESAM security modules employ the aes algorithm more safer than DES, effectively prevent intelligent electric meter and are maliciously entered
Invade, and then the telecommunication of safety can be carried out.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is a kind of structured flowchart of anti-electricity-theft intelligent electric meter of the present invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
The present invention is elaborated with reference to Fig. 1.
A kind of anti-electricity-theft intelligent electric meter, including it is MCU, AC/DC module, DC/DC modules, clock module, metering module, aobvious
Show module, current sample module and voltage sample module, it is characterised in that：Also include communication module, the ESAM moulds being connected with MCU
Block, alarm module, magnetic latching relay, Magnetic Sensor and light coupling relay, the magnetic latching relay and light coupling relay
Output is series at externally fed circuit.
In order to reduce influence of the temperature to electronic component i.e. temperature drift, further, the intelligent electric meter also includes temperature
Sensor and radiator.
In order to prevent that further, the ESAM security modules enter line number to intelligent electric meter using aes algorithm by malicious intrusions
According to encryption and decryption.
In order to ensure the intelligent electric meter energy wireless telecommunication, further, the communication module is GPRS communication moulds
Block or NB-IoT communication modules.
Preferably, the communication module uses DL/T645-2007 communication protocols.
Inputted when Magnetic Sensor detection external magnetic field value is converted to electric current to MCU, MCU judges whether that exceeding magnetic keeps relay
The quantity of magnetism needed for device closure, now magnetic latching relay be in can not off-state, MCU starts alarm input to alarm module, leads to
Cross communication module and alarm signal is uploaded to remote supervisory and control(ling) equipment, while MCU judges to open if ammeter electricity is less than or equal to zero
Light coupling relay powers off power supply circuit, avoid not breaking in the case of arrearage electric user can also normal electricity consumption situation.
In summary, by adopting the above-described technical solution, intelligent electric meter of the present invention also can be just under high-intensity magnetic field
Normal off electricity；Influence of the temperature to electronic component is reduced, improves the measurement accuracy of ammeter；ESAM security modules employ ratio
Aes algorithm safer DES, intelligent electric meter is effectively prevent by malicious intrusions, and then can carry out the telecommunication of safety.
