[0029] The present application relates to a communication conversion device for a power terminal. The communication conversion device can be connected to a sensor or a control device, such as an energy controller. The communication conversion device can integrate multiple different types of functions required by the energy controller, such as data acquisition, data communication, etc. The communication conversion device can be connected to a host, such as a host computer, for receiving the instruction data of the host computer to implement the use or switching of different virtual modules. Specifically, the user can control the communication conversion device through the host to configure different virtual modules, such as DC analog quantity, CAN communication, etc., and support the real-time data acquisition and display of the energy controller to help the user monitor and analyze the system status. The user can also customize the module information and module data of the virtual module. For example, the user can generate instruction data through the application program of the host and send it to the communication conversion device, so that the hardware and software can work together. When the communication conversion device is connected to the host, the software can automatically identify and initialize the hardware, collect and display data in real time, and at the same time adjust the working mode of the module according to the user configuration.

[0030] As Figures 1 to 7 shown, the present application provides a communication conversion device 1 for a power terminal, including: a communication module 12, a first control module 10 and a second control module 11 that are connected to each other.

[0031] In some embodiments, the first control module 10 may be configured to process the collected data from the energy controller 2 based on the corresponding functions of the virtual modules to generate test data for the energy controller 2. The second control module 11 may be configured to control the first control module 10 to simulate a virtual module with corresponding functions and switch the first control module 10 from one virtual module to another according to the instruction data from the host 3. The communication module 12 may be communicatively connected to the energy controller 2 and the host 3 for the interaction of various types of data.

[0032] In some embodiments, the instruction data may carry data information such as the specific functional module, module information, and module data that the first control module 10 needs to simulate or switch. After the second control module 11 processes the instruction data to obtain the data information, it may synchronize the data information to the first control module 10. The first control module 10 may simulate a virtual module with corresponding functions according to the data information. After the energy controller 2 generates the collected data based on the virtual module, it may send the data to the first control module 10 via the communication module 12. The first control module 10 may generate test data based on the collected data. The communication module 12 may send the test data to the energy controller 2 and / or the host 3. The first control module 10 may switch to other virtual modules according to the instruction data to generate multiple test data.

[0067] In this application, after the first control module 10 is simulated into a virtual module with corresponding functions, the first control module 10 and the second control module 11 respectively process various types of data from the energy controller 2 and from the host side 3. At the same time, by setting the communication module 12, the transmission of various types of data between the energy controller 2 and the host side 3 is realized. In this case, multiple functions required for the production test of the energy controller 2 can be realized based on the cooperation between the host side 3 and the communication conversion device 1, that is, multiple functions of the required hardware modules can be integrated. Therefore, the dependence of the energy controller 2 on the hardware modules can be reduced, and thus it is convenient to perform data acquisition, testing, and control of the energy controller 2. By reducing the hardware requirements, the system cost can be reduced, and the flexibility can be further improved.
