Description
Technical Field
The invention relates to the field of electric meters, in particular to a registration method of an electric meter.
Background
The intelligent power grid realizes remote information acquisition through an IP network, and the ammeter is used as terminal equipment for remote electric quantity information acquisition and is distributed in vast cities, rural areas and industrial occasions, and the use environment is complex. Because the number of the ammeter terminals is large, the distribution is wide, the installation time is different, and how to realize timely and reliable network connection between each ammeter and the electricity selling management system database and timely report data becomes a key link for intelligent power grid information acquisition.
Aiming at the problems, a server/client model is generally adopted in the prior art to realize data interaction between the ammeter and the electricity selling management system. The electricity selling management system (hereinafter referred to as a master station) is used as a server and is provided with a fixed IP address, the electricity meter is used as a client, and after the electricity meter is installed, the electricity meter actively logs in the master station IP to establish connection. After receiving the login information, the master station can acquire the information of the ammeter, and the master station is connected with the ammeter through heartbeat; however, since the ammeter is used as a client, no fixed IP address exists, and the data can be read only when the ammeter is connected. The primary station cannot access the meter information once the heartbeat is lost. Further improvements are needed for this purpose.

step 3, judging whether the master station receives a registration message of the ammeter in a set time, if so, sending confirmation information to the ammeter to inform that the ammeter registration is successful, and switching to step 4; if not, the ammeter retransmits the registration message to the master station according to the preset time interval, and the step 3 is continued;
step 4, after the ammeter receives the registration confirmation information, stopping registration, and switching to step 5 until the next time that the IP address or monitoring port information of the ammeter is changed is detected, re-dividing the ammeter into registration messages according to the steps and re-sending the generated registration messages to the master station to initiate the registration messages;
and 5, after the ammeter registration is successful, the master station establishes a temporary session with the ammeter according to the formulated acquisition task, reads ammeter data after the temporary session is established, and finishes the session and disconnects after the ammeter data is read.
The registration message is generated according to one or more of a logical device name, an ammeter number ID, an ammeter IP address, a monitoring port and MAC address information.
In order to avoid blocking the network channel, preferably, in the step 2, when it is detected that the electric meter needs to register, the electric meter waits for a first time T2, and initiates a registration message to the master station after the first time T2 expires.
Further, the condition that the ammeter needs to be registered is ammeter reset or IP information change.
In order to further reduce the network congestion probability and improve the data communication acquisition rate, the method for retransmitting the registration message by each ammeter in the step 3 comprises the following steps:
step 3-1, initializing retransmission times when the master station does not receive a registration message sent by the ammeter for the first time; wherein the initial value of the number of retransmissions is 0;
step 3-2, judging whether the retransmission times at the moment reach an upper limit value CNT, if so, waiting for a third time T3, ending after the third time T3 is up, and waiting for the ammeter to be registered again; if not, the ammeter waits for the second time T1 and retransmits the registration message, and after adding 1 to the current retransmission times, the ammeter updates the current retransmission times, and then the ammeter shifts to the step 3-3;
step 3-3, judging whether the master station receives a registration message of the ammeter in a set time, if so, stopping registration; if not, go to step 3-2.
The second time T1 is configured according to the installation capacity of the station and the network condition in order to maximally solve the network congestion and affect registration.
Further, the third time T3 is configured according to the number of installed electric meters in the area and the network condition.
In order to save communication traffic, preferably, the communication between the electricity meter and the master station is kept in a short time connection, and the connection is automatically disconnected after each communication is completed for T minutes. Therefore, the connection is automatically disconnected after the communication is completed for T minutes, so that the communication connection between the ammeter and the master station is not required to be kept for a long time, and the communication flow is saved.
The communication between the electric meter and the master station is various, wherein the first preferable mode is that the electric meter is communicated with the master station through a communication module.
The second mode of communication between the ammeter and the main station is that a wireless module is arranged in the ammeter, and the wireless module is communicated with the main station through a collector.
Compared with the prior art, the invention has the advantages that: taking an ammeter as a server, taking a master station as a client, controlling access to ammeter data by the master station, and reducing the pressure of the server; the master station is used as a client and is provided with a fixed IP address for interception and reporting, and the master station is informed of information in a registration mode when the ammeter logs in each time or dynamic IP changes. By the method, the master station can know the real-time IP information of each ammeter, so that only the master station needs a fixed IP address, the meter IP address is dynamically produced, and IP resources are saved.
