Embodiment 1

[0028] see figure 1 A flow chart of a control method for a smart meter is shown. The method is described from the controller side of the smart meter as an example, and includes the following steps:

[0029] Step S102, receiving the current current data of the specified line and the load information currently connected to the specified line from the data collector of the smart meter; the load information includes the load type, the rated current value of the load, and the rated power value of the load;

[0030] Step S104, according to the current load type of the specified line, search for the normal current threshold corresponding to the load type in the pre-established current threshold library, and judge whether the received current data is abnormal current data according to the normal current threshold; wherein, the normal current The threshold includes a normal current lower limit and a normal current upper limit; for example, when the current data is outside the normal cu...

Embodiment 2

[0044] For the control method for the smart meter provided in the first embodiment, the embodiment of the present invention provides a control device arranged on the controller side of the smart meter, see figure 2 As shown, the device includes the following modules:

[0045] The data receiving module 22 is used to receive the current current data of the specified line and the load information currently connected to the specified line from the data collector of the smart meter; the load information includes the load type, the rated current value of the load and the rated power value of the load ;

[0046] The abnormality judgment module 24 is used for searching the normal current threshold corresponding to the load type in the pre-established current threshold library according to the current load type of the designated line, and judging whether the received current data is abnormal current data according to the normal current threshold; Wherein, the normal current threshold...

Embodiment 3

[0059] In conjunction with the control device for smart meters provided in the foregoing embodiments, see image 3 As shown, the embodiment of the present invention provides a smart meter, including the control device 10 of any one of the second embodiment, and also includes a data collector 20 connected to the control device 10, an action executing component 30, a display screen 40, SIM card 50 and siren 60; Wherein, action execution unit 30 comprises circuit breaker, leakage protector, short circuit protector or overcurrent protector;

[0060] The data collector 20 is used to collect the current current data of the specified line and the load information currently connected to the specified line, and send the current data and load information to the control device;

[0061] The action execution component 30 is used to receive the action execution instruction sent by the control device, and execute the operation corresponding to the action execution instruction;

[0062] The...

Abstract

The invention provides a smart electric meter and a control method, a control device and a control system thereof. The control method comprises the following steps: receiving current data and load information sent by a data collector; querying in a current threshold library for a normal current threshold corresponding to a load type according to the load type, and judging whether the received current data is abnormal current data or not according to the normal current threshold; when the current data is abnormal current data, querying in an abnormality database for an abnormality cause corresponding to the abnormal current data; determining a solution corresponding to the abnormality cause according to the abnormality cause and a solution database; triggering an action execution part to execute a corresponding operation; sending announcement information to a pre-associated mobile terminal through an SIM card in a smart electric meter; and sending display information to the display screen of the smart electric meter so the display screen can display the display information. Improvement can be made for the problem that the existing electric meter is of low safety and reliability.

Description

technical field [0001] The invention relates to the technical field of electric meters, in particular to a smart electric meter and its control method, device and system. Background technique [0002] At present, due to poor management of electricity consumption, accidents such as family fires and personal electric shocks occur from time to time. Even if the existing electricity meters are transformed by the power supply company, most of them are mechanical transmission devices, which cannot respond to failures in time. Moreover, the action sensitivity is not high, and it is prone to misoperation, etc., and the reliability is poor. In addition, the user cannot know the exact reason, so the user experience is not high. [0003] Aiming at the problem of low safety and reliability of the electric meter in the above prior art, no effective solution has been proposed yet. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a s...
