Therefore, it can be seen that this application acquires earlier after the power pin and the data enable pin of IO interface control GPRS module that utilize smart electric meter the type information of GPRS module, again according to the type information, to the corresponding AT instruction is sent to the GPRS module, in order to control the GPRS module is connected to the network, then according to the communication trigger information who monitors, accomplishes corresponding communication, can match with the GPRS module of different grade type like this to accomplish smart electric meter communication, the commonality is strong, and utilizes smart electric meter directly to supply power for the GPRS module, has practiced thrift communication cost.

In this embodiment, when the smart meter has an event status word or a load curve that needs to be actively pushed to the network server, the triggered communication behavior is to actively push data to the network server. When data needs to be actively pushed to the network server side, whether a pushing channel between the intelligent electric meter and the GPRS module is closed or not is judged firstly.
Step S26: and if the push channel is closed, sending a corresponding instruction to the GPRS module, controlling the GPRS module to establish the push channel, and sending target push data to the GPRS module through the push channel.
It can be understood that, if the push channel is closed, the smart electric meter sends a corresponding AT instruction to the GPRS module, controls the GPRS module to establish the push channel, and then sends target push data to the GPRS module through the push channel.

In order to prevent the situation that all the intelligent electric meters send data to the network server side at the same time and occupy a large amount of server resources, so that server paralysis occurs, before judging whether the pushing channel is closed, discrete time delay needs to be performed on the pushing action of the GPRS module according to the meter number of the intelligent electric meter. Specifically, a program used for discrete time delay is prestored in the intelligent electric meter, and the intelligent electric meter operates the program before judging whether the push channel is closed, so that discrete time delay is performed on the push behavior of the GPRS module.
It can be understood that after the intelligent electric meter sends the target push data to the GPRS module, the push channel is controlled to be disconnected after a preset time. The preset time period may be set by an object identification system (object identification system) in the smart meter. Wherein the obis is used to provide a unique identification code for each commonly used data item in the metering device.

Step S35: and if the communication behavior is that the network client end points copy the data of the intelligent electric meter, analyzing the first remote frame data transmitted by the GPRS module, and determining the data copied by the target point.
In a specific implementation process, after receiving first remote frame data sent by the network client, the GPRS module directly transmits the first remote frame data to the smart meter without any processing.
Step S36: and converting the target point copied data into second remote frame data, and sending the second remote frame data to the GPRS module so that the GPRS module can upload the second remote frame data to the network client.
In a specific implementation process, if the GPRS module receives first remote data of the intelligent electric meter data copied by the network client, a communication behavior of the network client for copying the intelligent electric meter data by the endpoint is triggered. Specifically, after receiving the first remote frame data, the GPRS module sends a corresponding AT instruction notification table to the smart meter, after receiving the AT instruction notification table, the smart meter sends a corresponding AT instruction to the GPRS module to acquire the first remote frame data and a remote spot-copied ip address as a socket number, analyzes the first remote frame data, determines target spot-copied data, converts the target spot-copied data into second remote frame data after acquiring the target spot-copied data, and sends the second remote frame data to the GPRS module, so that the GPRS module uploads the second remote frame data to the network client.
