Problems solved by technology

[0002] The 2013 version of the State Grid Corporation of China's technical specifications for smart energy meters series stipulates the technical requirements, type, function, communication and safety certification of smart energy meters. However, the procedures in the energy meters manufactured by various energy meter manufacturers are different. After an active report event occurs on the energy meter, when performing a large message reading test on the energy meter, if there is a loophole in the program of the energy meter, it may be because the energy meter cannot determine whether the read data is an active report event or long data frame data. Make the energy meter crash and restart, resulting in power loss

Embodiment Construction

[0019] Combine below figure 1 And embodiment the present invention is described further.

[0020] Such as figure 1 as shown, figure 1 To detect the flow chart of this method, it is finally judged whether there are loopholes in the program by observing the working status of the electric energy meter. This embodiment adopts the following steps to realize:

[0021] 1) Apply the rated voltage to the smart watt-hour meter, set the smart watt-hour meter through the carrier or RS485 port and read the data items in the smart watt-hour meter.

[0022] 2) Read the running status feature word of the smart energy meter to ensure that the smart energy meter actively reports that the subsequent frame is turned on (the value is "1"). If it is not turned on, set it to the turned on state through the meter reading software.

[0023] 3) Read the active reporting status word of the smart energy meter event to ensure that no active reporting event has occurred in the smart energy meter. If th...

Abstract

The invention discloses an intelligent electric energy meter large message reading test detection method. The method includes the following steps that: 1, rated voltage is applied to an intelligent electric energy; 2, the operating state feature words of the intelligent electric energy meter are read; 3, whether intelligent electric energy meter' actively reporting subsequent frames is enabled is judged, if intelligent electric energy meter' actively reporting subsequent frames is not enabled, the intelligent electric energy meter is set to an intelligent electric energy meter' actively reporting subsequent frame enabled state through meter reading software, and the method returns to step 2, if the intelligent electric energy meter' actively reporting subsequent frames is enabled, a step 4 is executed; 4, intelligent electric energy meter event active report state words are read; 5, whether an intelligent electric energy meter active report event occurs is judged, if an intelligent electric energy meter active report event occurs, the intelligent electric energy meter active report event is cleared through the meter reading software, and the intelligent electric energy meter is recovered to an active report event non-occurrence state, and the method returns to the step 4, if an intelligent electric energy meter active report event does not occur, a step 6 is executed; 6, intelligent electric energy meter event active report pattern words are read, and one of enabled active report events is selected; an active report event is generated through software simulation; 8, long data frame data of the intelligent electric energy are read; and 9, the working state of the intelligent electric energy meter is observed.

Description

technical field [0001] The invention relates to a test and detection method for copying and reading a large message of an intelligent electric energy meter, which belongs to the field of electric energy meter detection. Background technique [0002] The 2013 version of the State Grid Corporation's technical specifications for smart energy meters series stipulates the technical requirements, type, function, communication and safety certification of smart energy meters. However, the procedures in the energy meters manufactured by various energy meter manufacturers are different. After an active report event occurs on the energy meter, when performing a large message reading test on the energy meter, if there is a loophole in the program of the energy meter, it may be because the energy meter cannot determine whether the read data is an active report event or long data frame data. Make the energy meter crash and restart, resulting in power loss. Contents of the invention [...
