In this scenario, the controlled station can refer to an electric device, such as an electric meter, accessing the DTU device. The DTU equipment is connected to an upper computer (for example, the upper computer is connected with the DTU equipment through an RS232 bus). The upper computer stores a protocol parameter list and a protocol content list. The protocol parameter list is used for matching link layer communication parameters of the electric meter, and the protocol content list is used for matching protocol content parameters of electric power communication protocol contents of the electric meter. For convenience of understanding, a multifunctional three-phase active electric energy meter (hereinafter referred to as "electric meter") supporting the 104 protocol is taken as an example of a controlled station, and the electric meter is connected to a DTU device, namely the control station. The upper computer is connected and communicated with the DTU equipment through an RS232 bus. And the upper computer sends an automatic detection instruction, and the DTU equipment starts to automatically detect the communication parameters and the communication protocol of the ammeter based on the instruction. The specific principle and process of detection can be: the upper computer stores a large number of conventional areas, wherein the protocol parameter area is the first protocol parameter area, and the protocol content area is the second protocol content area. The protocol parameter area is used for matching link layer communication parameters of the electric meter, the link communication parameters (such as 9600bps and 8-bit even check parameters) of the electric meter are found in a limited parameter list through a running dictionary method, then the electric power communication protocol (such as IEC104 protocol) of the electric meter is found by using the data in the protocol content area through the same method, and therefore protocol self-identification of the electric meter is completed.

In the process, the control and the monitoring between the control station and the controlled station are intermittent, and the electric meter data is continuously monitored. The server receives only messages of the conditional cause of the activation of the change balance occurrence trigger.
