Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric energy meter, in particular to an electric energy meter electricity larceny prevention method and system. BACKGROUND

[0002] The existing electric energy meter electricity larceny prevention method mostly needs to cooperate with the hardware peripheral circuit to detect, such as bypass electricity larceny detection and magnetic interference electricity larceny detection. The bypass electricity larceny detection needs the electric energy meter to support two-way current sampling circuit, and the magnetic interference electricity larceny detection needs the electric energy meter to have a magnetic detection chip. When the electric energy meter detects that the electricity larceny behavior occurs, the corresponding event is recorded, and then the alarm lamp is lit, but the user can normally use electricity. The specific electricity larceny prevention process is as follows: the alternating voltage on the electric energy meter starts to work normally; the electric energy meter detects the electricity larceny in real time in the second task, that is, each second judges various electricity larceny events such as bypass and magnetic interference; if the electricity larceny event occurrence condition is met, the corresponding electricity larceny event is recorded and stored in the storage chip for later reading by the staff. If the electric energy meter hardware supports the alarm lamp, the alarm lamp is lit to warn the staff that the meter has an electricity larceny event; if the electricity larceny event occurrence condition is not met, the judgment is continued in a loop; after the electricity larceny occurs, the user can normally use electricity. However, the existing technology has the following technical problems: 1. The electricity larceny detection needs to be assisted by the hardware circuit or chip to detect, which increases the cost; 2. The storage chip EEPROM storing important data such as electricity larceny events and electricity cannot be detected whether it is replaced, so that the confidentiality and accuracy of the electric energy meter data cannot be guaranteed; 3. After the electricity larceny occurs, the user can normally use electricity, and there is no any punishment metering measure, which is not conducive to the reasonable management of electricity.

[0021] Fig. 2 Fig. 2 shows a complete electric energy meter first power-on and electricity stealing prevention processing flowchart according to the present application. DETAILED DESCRIPTION

[0022] The following description is provided to enable any person skilled in the art to practice the present application. The preferred embodiments described below are only examples of the present application, and other obvious modifications can be made by those skilled in the art. The basic principles defined in the following description can be applied to other embodiments, modifications, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present application.

[0023] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0024] In conjunction with Figs. 1-2 The application discloses an electricity stealing prevention method and system for an electric energy meter, wherein the method comprises: first, power-on of the electric energy meter is required, and whether the current electric energy meets the power-on condition is judged, such as whether the voltage, current and other parameters of the electric energy meter connected to the power grid meet the power-on requirement. If the power-on requirement is met, the power-on operation of the electric energy meter is performed. After the power-on of the electric energy meter is completed, the first data of the last 4 bytes in length is read by the main chip of the electric energy meter, and the storage chip in the application preferably adopts EEPROM, and the last 4 bytes of the EEPROM are the storage area of the first data. Further, the second data of the fixed flash area of the main chip storage area is obtained by the main chip of the electric energy meter. Further, the first power-on mark configuration data of the first data and the second power-on mark configuration data for the second data are pre-configured. Wherein the application stores the power-on mark configuration and identification strategy in the main chip of the electric energy meter, the strategy is used to judge whether the current storage chip and the electric energy meter are new, and after the first data of the storage chip and the second data of the main chip of the electric energy meter are obtained, the current electric energy meter is output whether it is a new electric energy meter or whether there is a power stealing behavior of replacing the storage chip. The power stealing punishment strategy and the power stealing alarm strategy are also pre-stored in the main chip of the electric energy meter, and the power stealing punishment and the external power stealing alarm are performed respectively. It should be noted that the above strategy can be stored in the electric energy meter or the upper computer in the form of a computer program, and the corresponding first power-on mark configuration data and the second power-on mark configuration data for the second data can be configured in the upper computer.

[0025] Specifically, when the electric energy meter performs power-on, first, the first data of the last 4 bytes of the storage chip EEPROM is read by the main chip of the electric energy meter, and it is judged whether the first data is same as the first power-on mark configuration data. The first power-on mark configuration data in the application can be configured as 0xA5, if the first data of the last 4 bytes of the storage chip EEPROM of the current electric energy meter is also 0xA5, it is indicated that the EEPROM of the current electric energy meter is a non-new storage chip. Further, the second data stored in the fixed area of 4 bytes of the flash of the storage area of the electric energy meter is read by the main chip, if the read second data is same as the second power-on mark configuration data, it is determined that the current electric energy meter is a non-new electric energy meter. At this time, according to the preset power-on mark configuration and identification strategy, the determination result of the first data and the second data can determine that the current electric energy meter is in normal state, and the current electric energy meter can normally meter the user's electricity.

[0026] If the first data of the last 4 bytes of the EEPROM read by the main chip of the electric energy meter is not the preset first power-on mark configuration data 0xA5, it is determined that the current EEPROM is a new storage chip. At this time, the current EEPROM storage chip may be a replaced storage chip, or it may be a new storage chip without power-on. Therefore, the main chip of the electric energy meter also needs to read the second data stored in the fixed area of 4 bytes of the flash of the storage area, if the read second data is same as the preset second power-on mark configuration data, for example, the second power-on mark configuration data in the application can be fixedly written as 0xBA, and the read second data is also 0xBA, it is determined that the current electric energy meter itself is a non-new electric energy meter which has been initially powered on. Further, according to the power-on mark configuration and identification strategy, the determination result of the first data and the second data can determine that the current electric energy meter has a non-normal storage chip electricity stealing behavior. The main chip of the electric energy meter triggers the electricity stealing punishment strategy and the electricity stealing alarm strategy.

[0027] It is worth mentioning that the application can effectively reduce the misjudgment phenomenon of single identification by configuring power-on identification for the storage chip and the storage area of the main chip of the electric energy meter respectively, and through the linkage identification and judgment mode. The linkage identification and judgment can identify whether it is a new behavior of the whole electric energy meter, and the configuration strategy of the power-on identification is executed for each whole new electric energy meter. The configuration strategy of the power-on identification includes: if the current electric energy meter is powered on, the electric energy meter main chip reads the first data stored in the last 4 bytes of the storage chip and the second data stored in the flash fixed area of the storage area of the main chip in turn, and then identifies the storage chip corresponding to the first data as a new storage chip and a new electric energy meter main chip according to the identification strategy of the power-on identification. At this time, the electric energy meter main chip starts the power-on identification configuration strategy, and configures the first power-on mark configuration data and the second power-on mark configuration data in the host computer to the storage positions corresponding to the first data and the second data in turn. After completing the power-on identification configuration, the new electric energy meter can identify the electricity stealing behavior of replacing the corresponding storage chip. And execute the electricity stealing punishment strategy and the electricity stealing alarm strategy corresponding to the electricity stealing behavior. If the electricity stealing behavior occurs, enter the electricity stealing indication, such as liquid crystal only displaying OPENED, not displaying other important information such as power, and the alarm light is on, reminding the power bureau staff that the electric energy meter has replaced EEPROM, tampered with important information such as power consumption of the electric energy meter. At this time, the electric energy meter does not measure according to the normal metering, and needs to enter the punitive metering stage, and measures according to the rated voltage and the maximum current, which plays a kind of punishment on the electricity stealing behavior. After confirming the electricity stealing behavior and processing, the first power-on mark configuration data is reconfigured for the last 4 bytes length area of the current replaced EEPROM, so as to detect the next replacement electricity stealing behavior.
