[0065] Example

[0066] like Figure 1 As shown, this embodiment provides an integrated communication system channel test system based on software radio architecture, including an integrated communication system hardware platform and host computer test software, wherein the integrated communication system hardware platform is composed of a universal channel module, a security and confidentiality module, a universal control module, a universal switching module, a universal information processing module, and a universal storage module connected through a backplane module bus, and the host computer test software is connected to the universal control module.

[0067] like Figure 3 As shown, the integrated communication system channel testing method based on software radio architecture provided in this embodiment includes the following steps:

[0068] Step 1: The integrated communication system is powered on and relevant initialization work is completed. The host computer test software is started. The initialization work includes initializing relevant hardware modules, configuring the addresses of various hardware modules, starting the software radio platform, etc.

[0069] Step 2, the host computer test software connects to the hardware abstraction layer device of the universal control module. In this embodiment, the host computer software connects to the hardware abstraction layer device through the external Ethernet port set on the universal control module through the hardware abstraction layer device IP address + port number;

[0070] Step 3: The host computer test software generates a test data packet for the target hardware module to be tested and sends it to the hardware abstraction layer device of the general control module, such as Figure 4 As shown, the front part of the data packet is the logical address of the destination hardware module to which the data packet is sent, and the back part is the data packet content;

[0071] The hardware modules on the backplane module have different logical addresses. The module to which the data packet is sent is determined according to the logical address. Table 1 shows the logical addresses corresponding to the modules used in this embodiment.

[0072] Table 1 Logical addresses of target hardware modules

[0073]

[0074] Step 4: The hardware abstraction layer device parses the test data packet in the write function, determines the target hardware module of the data packet according to the logical address contained in the data packet, and calls the target hardware module interface function to send the test data packet to the target hardware module. In this embodiment, the hardware abstraction layer device write function is:

[0075] Mhal_Write(unsigned char*message,UINT16 length)

[0076] Where message is the data packet generated in step 3 containing the logical address information of the target hardware module, and length is the length of the data packet;

[0077] Step 5: The target hardware module receives the test data packet and generates a response data packet according to the test protocol, and sends the response data packet to the public buffer of the general control module;

[0078] The test protocol is formulated when each module software is implemented, that is, the unified regulations for sending and receiving related data packets between two hardware modules. In this embodiment, a channel test is performed between the general control module and the general information processing module, wherein the general control module sends two test data packets in the following format to the general information processing module:

[0079] Test data packet 1: 00A2, 0011, 0022, 0033, 0044

[0083] Response data packet 2: 00A0, 0C0C, 0D0D, 0E0E, 0F0F;

[0084] Step 6: The hardware abstraction layer device of the general control module reads the target hardware module response data packet from the public buffer and sends it to the host computer test software, as follows:

[0085] Start the public buffer read thread in the hardware abstraction layer device. When data is detected in the public buffer, the data read thread will transparently transmit the data to the host computer test software. The format of the hardware abstraction layer device reading response data packet function is:

[0086] MHAL_Read(unsigned char*message)

[0087] The read response data packet is located in message.

[0088] Step 7: The host computer test software receives the response data packet and checks the data packet based on the test protocol to determine whether the channel between the system general control module and the target hardware module is normal;

[0089] The local database of the host computer test software stores the preset response data packet format of each hardware module. When executing a module test, the received data packet is compared with the preset response packet to determine whether the tested channel is normal.

[0090] The present invention and its implementation methods are described schematically above, and the description is not restrictive. The drawings show only one implementation method of the present invention, and the actual structure and method are not limited thereto. Therefore, if a person skilled in the art is inspired by it and, without departing from the purpose of the invention, designs a structure, method flow and embodiment similar to the scheme without creativity, they shall all fall within the protection scope of the present invention.
