S201: at the first time according to the networking saved for each intelligent meter, judge corresponding at the first time in the networking First time period in whether receive the networking solicited message that corresponding intelligent meter is sent.
A kind of method of network entry of intelligent meter provided in an embodiment of the present invention is applied to application server.
Application server is directed to each intelligent meter, preserves the networking first time of the corresponding intelligent meter, application server For each intelligent meter save networking at the first time can be identical, can also entirely different or part it is identical.And Application server can determine its corresponding first time period, such as can according to the networking at the first time according to default rule Be comprising the networking at the first time, length be setting value a period, preferably the networking at the first time be this first Minimum value in period.
For example, the networking that application server is saved for some intelligent meter is at the first time 8:00 on October 1st, 2016, Corresponding first time period can be 8:00-8:10 on October 1st, 2016, therefore be directed to the intelligent meter, and application server judges Whether the networking solicited message of intelligent meter transmission is received in this period of 8:00-8:10 on October 1 in 2016.
S202: it if it is judged that for when being, when the device number information for judging to carry in the networking solicited message, applies Identifier information, using key information and the device number information itself pre-saved for the intelligent meter, using identifier information, When consistent using key information, unpaired message is sent to the intelligent meter, so that intelligent meter is at set time intervals, is generated more Networking first time after new, and the application server is at set time intervals, generates updated networking first Time.
If application server receives the networking of intelligent meter transmission in the corresponding first time period at the first time that networks Solicited message, wherein application server is the networking solicited message that intelligent meter transmission is received by base station, needs to sentence at this time The device number information that is carried in the networking solicited message of breaking, using identifier information, using key information and itself for should Device number information that intelligent meter pre-saves, using identifier information, whether consistent using key information, if unanimously, passed through Base station sends unpaired message to intelligent meter, and the unpaired message includes application layer key information, device address information and network layer Key information.
Meanwhile application server is at set time intervals, updated networking is generated at the first time, so as to intelligent meter It is networked again at the first time according to the updated networking.
Specifically, the networking can be generated at the first time based on preset algorithm, and application server and intelligent meter are adopted The networking is generated at the first time with identical algorithm, thus guarantee the time consistency that the two generates, and the networking at the first time can To be generated based on program.In addition, the record in order to realize the time interval, application server may include timer, application The time interval that server is set according to timer passes through the updated networking first of the operation Program Generating in application server Time.The time interval can be shorter time, such as 20s, 30 minutes etc., be also possible to longer time, such as 5 days, 10 days etc..
For example, the time that application server sends unpaired message is 8:00 on October 8th, 2016, the time of timer setting Interval can be 2 days, then application server passes through the operation Program Generating in application server in 8:00 on October 10th, 2016 At the first time, the updated networking can be at the first time 8:00 on October 15th, 2016 for updated networking, then exist In on October 15th, 2016 corresponding 8:00-8:10 in 15 days October 2016 period of 8:00, application server judges whether to connect Receive the networking solicited message that corresponding intelligent meter is sent.
Since in embodiments of the present invention, application server is directed to each intelligent meter, it is right at the first time to judge to network at it Whether networking solicited message that corresponding intelligent meter send is received in the first time period answered, if not, starting intelligent meter is different Often alarm, so that the judgement true and false to intelligent meter is realized, if receiving networking solicited message, after verification passes through, to this Intelligent meter sends unpaired message, so that intelligent meter is at set time intervals, generates updated networking at the first time, still It is updated networking be at the first time intelligent meter at set time intervals, generated by preset algorithm, therefore, false intelligence Energy table cannot obtain updated networking at the first time, therefore further ensure the safety of intelligent meter, so as to avoid operation The loss of enterprise.
Certainly, if the device number information carried in the networking solicited message, believed using identifier information, using key Breath with itself be directed to device number information that the intelligent meter pre-saves, using identifier information, inconsistent using key information, this When, application server determines that intelligent meter verification does not pass through, after application server does not send unpaired message and update to intelligent meter Networking at the first time.
S203: if it is judged that when being no, start intelligent meter abnormal alarm.
If application server does not receive entering for intelligent meter transmission in the corresponding first time period at the first time that networks Net solicited message, application server starts intelligent meter abnormal alarm at this time.
Specifically, because application server preserves its corresponding networking at the first time for each intelligent meter, if When not receiving the networking solicited message that corresponding intelligent meter is sent in a certain corresponding first time period at the first time that networks, because Application server itself records the identification information for having the intelligent meter, therefore when starting intelligent meter abnormal alarm, can carry the intelligence The identification information of energy table, wherein the identification information of the intelligent meter can be the letter of the unique identifications intelligent meter such as device number of intelligent meter Breath.
Due in embodiments of the present invention, for each intelligent meter, judging when it networks first time corresponding first Between the networking solicited message that corresponding intelligent meter is sent whether is received in section, if not, starting intelligent meter abnormal alarm, thus Realize the judgement true and false to intelligent meter.
