The anti-electricity-stealing intelligent meter tail with the communication function has the advantages of simple installation, simplified construction difficulty, improved installation quality and no occupation of any communication interface, and realizes communication with a master station or handheld equipment.
Example 2, as shown in fig. 1 and 2; the utility model provides a take anti-electricity-stealing smart meter tail of communication function, it is including:
the utility model provides a take communication function's anti-electricity-stealing smart meter tail, it includes: the method comprises the following steps: the device comprises a meter tail sealing unit, a 485 communication unit, an LORA communication unit and a temperature detection unit;
the meter tail sealing unit is arranged at the tail end of the meter and seals the whole meter tail, so that a user cannot open the meter tail or steal electricity across the meter through an electric wire of the meter tail;
485 communication unit, the built-in 485 chips of smart meter tail, this chip is connected to the 485 interface of table meter, and simultaneously, the table tail can be external out with the 485 interface of table meter, connect the 485 interface to the personnel of convenient power supply company, or carry out 485 half carrier and check meter, the smart meter tail once fixed, begin promptly with 485 communication, in case unable with table meter communication, just it has been opened by the people for meaning the table tail, through the built-in number of times of opening of detection table tail, the judgement of opening the number of times is judged from table tail and forceful electric power connection and 485 junction. That is, if the forceful electric power of smart meter tail disappears, the smart meter tail can communicate with the electric energy meter through 485 this moment, knows the state of electric energy meter, if the electric energy meter also cuts off the power supply, then the meter tail can regard this as a conventional power failure action. If the strong electricity of the smart meter tail disappears, but the electricity meter still has electricity, the smart meter tail is considered to be opened. At the moment, the internal software can automatically record, and once the meter tail is installed back again, the information is reported to the master station through 485 communication. The zero line current and the live line current in the meter are read at regular time through 485, once a user steals electricity, the difference value of the zero line current and the live line current is increased, and the method can prevent electricity from being stolen around the meter without changing the meter tail.
The temperature detection unit is used for detecting extra temperature, detecting the problems of the surrounding environment and the tail of the anti-electricity-stealing meter, and recording and reporting events for abnormal temperature;
the LORA communication unit can check the state of the tail of the intelligent meter in a long distance (100 meters) through a handheld LORA palm machine, and is used for old meters and electric energy meters incapable of reporting states.
The specific implementation process of the invention is as follows:
(1) the smart meter tail is connected to the AC220V screw and the RS485 screw of ammeter through the telescopic spring post on, 2 strong electricity, 2 weak electricity.
(2) The strong electric spring column has the following functions: taking electricity from the tail of the intelligent meter; monitoring whether the meter tail is detached by a person, if so, cutting off the meter tail strong electricity, and automatically recording a power-off event by an internal processor; at the moment, the state of the electric meter is detected through the 485 interface, and if the electric energy meter does not have electricity, a normal power failure event occurs; if the electric energy meter is charged, recording an exception.
(3) Weak current 485 spring post: and the 485 terminal is connected and used for communicating with the electric meter and reading the power failure state and the related data quantity of the electric meter.
(4) Considering that part of the electric meter is left open before the meter, sometimes the line is installed or handled and the user is powered down together with the electric meter. Thus, the data records only show anomalies and do not directly indicate electricity stealing behavior.
(5) And the LORA module is used for wirelessly receiving the data of the whole station area. Because the carrier link is invalid after the user disconnects the open, data summarization is carried out only through the wireless link, the communication distance of the LORA module is 5km in the open, and under the condition of shielding, the estimation is conservative according to the radius of 100 meters.
(6) The intelligent meter tail judges whether the electric meter is abnormal or not by reading the zero line current and the live line current of the electric meter, and if the two-phase current is unbalanced, abnormal acquisition is also carried out.
(7) The temperature detection unit is used for detecting the tail of the anti-theft electric meter and the ambient temperature of the anti-theft electric meter, the sensor is attached to the shell of the tail of the anti-theft electric meter, temperature detection can be achieved, and detected temperature abnormity is transmitted back to the control chip through the IIC communication interface.
(8) An operator can hold the LORA signal acquisition equipment in hand, and the LORA signal acquisition equipment moves in a platform area where the intelligent meter tail is installed, so that data of all meter tails can be acquired back (including temperature abnormity). An abnormal meter may be discovered.
The anti-electricity-stealing intelligent meter tail with the communication function has the advantages of simple installation, simplified construction difficulty, improved installation quality and no occupation of any communication interface, and realizes communication with a master station or handheld equipment.
