Fig. 1 is an exemplary block diagram of a dual-mode communication system according to some embodiments of the present application. As shown in fig. 1, in some embodiments, dual-mode communication system 100 may include a metering terminal 110 and a management terminal 120, which are described in detail below.
In some embodiments, the metering terminal 110 is configured to collect the metering information and/or the sensing information, and report the metering information and/or the sensing information to the management terminal.

In some embodiments, the metering terminal 110 may be an electricity meter that automatically collects electricity consumption information, and the electricity consumption information may be collected in the metering terminal 110. In some embodiments, the metering terminal may be a smart single-phase meter or a smart three-phase meter.
It can be understood that when the metering terminal 110 collects the electricity utilization information, the electricity utilization information is uploaded to the management terminal 120, so that the management terminal 120 counts and manages the electricity utilization information collected by the plurality of metering terminals 110.
The first dual-mode communication device 112 may be a device having two communication methods (for example, carrier communication and wireless communication). It is understood that the metering terminal may be connected to the management terminal via a carrier communication via the first dual-mode communication device. Further, the first dual-mode communication device is connected with a second dual-mode communication device in the management terminal in a carrier communication mode. Therefore, the first electric meter and the collector can transmit the electricity utilization information to the management terminal in a carrier communication mode.
In some embodiments, the first electric meter is in communication with the collector, wherein the number of the first electric meters is one or more and the number of the collector is one or more. The first dual-mode communication device in the first ammeter is connected with the first dual-mode communication device in the collector in a carrier communication mode and/or a wireless communication mode. In some embodiments, the first electric meter may also be in communication with the first electric meter, and the collector may also be in communication with the collector.
It can be understood that the plurality of first electric meters and the plurality of collectors may be connected to the management terminal in a tree type.
In some embodiments, the metering terminal may be a collector. The collector is used for collecting the sensing information and/or the metering information and reporting the sensing information and/or the metering information to the management terminal 120.
The collector can be a device with a data collecting function and can be used for collecting sensing information and/or metering information. The sensing information can be information detected by a sensor, and the metering information can be electricity utilization information acquired by the collector. It can be understood that the collector can collect the sensing information through the sensor and collect the electricity utilization information through the electricity meter.
It can be understood that the collectors may upload the collected sensing information and/or the electricity consumption information to the management terminal 120, so that the management terminal 120 may count and manage the sensing information and/or the electricity consumption information of the plurality of collectors.
The management terminal 120 is communicatively connected to the metering terminal 110 (i.e., the first meter and/or the collector), and the management terminal 120 is configured to receive the metering information and/or the sensing information. Wherein the management terminal 120 comprises a second dual mode communication device 122.
In some embodiments, the management terminal may be a device having a data management function, such as a concentrator, a zone convergence terminal, an energy controller, and the like. The management terminal has the functions of networking control, network maintenance management, data centralized reading and the like.
The second dual-mode communication device 122 is similar to the first dual-mode communication device 112 in structure and function, and is not described herein again. It can be understood that the management terminal may be connected to the collector or the first electric meter through carrier communication via the second dual-mode communication device.

In summary, as shown in fig. 1, when the management terminal needs to acquire the electricity meter information in the metering terminal 4, the metering terminal 4 needs to transmit the electricity consumption information to the management terminal through the metering terminal 3 and the metering terminal 2 by a carrier or wireless communication method.
When the carrier communication in the metering terminal 3 is disconnected and the wireless communication of the metering terminal 2 is disconnected, the metering terminal 4 can transmit the electricity consumption information to the metering terminal 3 in a wireless communication mode, switch to the carrier communication in the metering terminal 3 and transmit the electricity consumption information to the metering terminal 2, and then transmit the electricity consumption information to the management terminal.
Therefore, when switching to the bluetooth communication mode, it is not necessary to start transmission again from the metering terminal 4 by the wireless communication mode, but to connect to the metering terminal whose carrier communication is disconnected by the wireless communication. It can be understood that when the wireless communication is disconnected, the metering terminal which is disconnected from the wireless communication is connected through carrier communication, and the electricity utilization information and/or the sensing information are continuously transmitted. Therefore, the communication stability with the management terminal is ensured, and the efficiency of acquiring the electricity utilization information is improved.
It can be understood that, as shown in fig. 1, when the management terminal needs to obtain the electricity meter information in the metering terminal 6, the metering terminal 6 is required to transmit the electricity consumption information to the management terminal through the metering terminal 5 by a carrier wave or wireless communication mode.
When the carrier communication in the metering terminal 5 is disconnected, the metering terminal 6 may directly switch the wireless communication mode to be connected to the metering terminal 5, so that the metering terminal 5 transmits the electricity consumption information to the management terminal by wireless communication.
