[0002] As traditional energy sources become increasingly scarce, alternative energy sources (such as wind and photovoltaics) are developing rapidly and playing an increasingly important role in daily industrial production and residents' lives. However, single power generation equipment suffers from weaknesses such as low power, poor storage, and low utilization. This has led to the development of power generation and distribution systems composed of multiple energy devices and energy storage devices, namely microgrids.

[0003] A microgrid is an autonomous system capable of self-control, protection, and management. It is a distributed power generation system that can operate in parallel with an external power grid or in isolation. The emergence of microgrids has changed the traditional single power generation model and is an important way to solve the problem of utilizing new energy. Due to the increasing environmental problems and the increase in energy demand, distributed energy has been rapidly developed.

[0135] In the 4G communication module of the embodiment of the present invention, the model of the 4G communication module is EC200A-CNMiniPCIe-C, and the 4G communication module is externally connected through the KH_PCIE5.2H card slot. There are two ways to lead out the antenna of the 4G communication module. One is to directly install the RF connection cable from the 4G communication module to the casing using an IPEX to SMA connector; the other is to use an RF extension cable with IPEX at both ends to connect the antenna signal of the 4G communication module to the IPEX socket on the control board, and then transfer it out through the SMA connector. However, the SMA connector cannot be directly connected to the metal casing. The SMA interface needs to be isolated from the casing and covered with a T-shaped protective coil.

The antenna of the WIFI module is led out in the same way as the antenna of the 4G communication module, and two methods are also adopted. It can be output directly from the SMA connector, or it can be output to the casing using an IPEX to SAM connector. In the embodiment of the present invention, the antenna of the WIFI module is led out using the former method. If the latter method is to be used, a resistor and a seat need to be welded. The antenna of the WIFI module has been impedance matched, so a T-shaped protective coil needs to be added between the SMA interface and the metal casing.
