Embodiment 1
[0028] refer to figure 1 , a method for detecting a security access event of an electric meter provided by an embodiment of the present invention, wherein, when applied to an electric meter, the method includes the following steps:
[0029] Step S101 , acquiring an access request of the client; wherein, the access request carries the identity information of the client, the encryption mechanism of the client, the password information of the client, and the access content.
[0030] In this embodiment of the present invention, the client is generally a master station or a handheld unit. The identity information of the client includes but is not limited to: users, operators and administrators. The encryption mechanism may refer to the permission level, and the permission level includes but is not limited to: high-level permission level and low-level permission level. The password information of the client is associated with the encryption mechanism, that is to say, the password ...
Embodiment 2
[0064] refer to Figure 4 , a device for detecting a security access event of an electric meter provided by an embodiment of the present invention, wherein, applied to an electric meter, includes the following modules:
[0065] The obtaining module 11 is used to obtain the access request of the client; wherein, the access request carries the identity information of the client, the encryption mechanism of the client, the password information of the client and the access content;
[0066] The first determination module 12 is configured to determine the occurrence of a security access event based on the target detection information; wherein, the target detection information includes at least one of the following: an encryption mechanism of the client, password information of the client, and access content;
[0067] The second determining module 13 is used to determine the security access event type based on the identity information of the client and the security access event;

Abstract
The present invention provides a method and device for detecting a security access event of an electric meter, which relates to the technical field of smart grids, and includes: first obtaining an access request from a client; wherein the access request carries the identity information of the client, the encryption mechanism of the client, and the password of the client information and access content; then determine the occurrence of a security access event based on the target detection information; wherein, the target detection information includes at least one of the following: the client's encryption mechanism, the client's password information and access content; and then based on the client's identity information and security access events The security access event type is determined; finally, the security access event is recorded based on the security access event type and the preset coding table. The invention determines different types of security access events, and improves the comprehensiveness of the security access event types and the corresponding codes of the event types. Based on different types of security access events, the present invention can also cover various reasons for the failure of the client to access the electricity meter.
Description
technical field [0001] The present invention relates to the technical field of smart grids, and in particular, to a method and device for detecting a security access event of an electric meter. Background technique [0002] Smart meters are increasingly focusing on security modules, so by logging security access events, customers can be reminded of everything happening in meter communications. The prior art mainly records two types of electricity meter security access events, wherein the first type of electricity meter security access event is a low-level authority password error event, and the second type of electricity meter security access event is a high-level authority access failure event. The above two types of meter security access events are described in too general terms, that is, there are few event types and incomplete coding. Therefore, the prior art cannot cover the specific reasons why the client fails to access the meter. SUMMARY OF THE INVENTION [0003] ...
