Problems solved by technology

If the system control interface unit is designed by each module manufacturer, the technical solutions and circuit designs of each manufacturer are different, which will cause the following problems: 1) Intercommunication problems: the design capabilities and technical solutions of each contracting manufacturer are different, and the general interface designed is in the bus interface circuit. There will be differences in level, data / control timing, data frame format, communication reliability, etc., which will adversely affect the robustness and stability of the system bus, and various interface levels, signal sending and receiving formats and 2) Non-standard communication interfaces increase the difficulty of design: due to the lack of understanding of CNS system architecture, working methods and control timing by various contract manufacturers, it is difficult to guarantee the design The general interface with strong fault tolerance and stable reliability increases the difficulty of module design; 3) The system test is complex: the test of the communication interface is a complex test, among which the interface level, data frame format and other items are easy to test, but it involves For the testing of communication interface integrity and robustness, such as error detection, fault tolerance, and retransmission recovery, if the interface design of each module is not uniform and needs to be tested separately, not only is it difficult to build a test environment, but the test content is complicated and the workload is huge

Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the implementation methods and accompanying drawings.

[0023] refer to figure 1 . In a preferred embodiment described below, the multifunctional radio frequency module general interface system of the present invention includes a system control management module, a general bus interface module, and a general radio frequency module. The system control management module uses a high-speed digital signal processing chip as the main control core, and communicates with the universal bus interface module through a synchronous bus to complete the delivery of system control instructions and data, such as configuring system operating modes, operating parameters and other control commands. At the same time, it receives the response data frame from the universal bus interface module and the status info...

Abstract

The invention discloses a universal interface system for a multifunctional radio-frequency module, and belongs to the technical field of communication. The universal interface system comprises a system control management module, a universal bus interface module and a universal radio-frequency module, wherein the system control management module communicates with the universal bus interface module through a synchronous bus, and is used for issuing a system message, a control command and data, and receiving and processing self-check and state information reported by the universal radio-frequency module through the universal bus interface module at the same time; the universal bus interface module is a bridge between the system control management module and the universal radio-frequency module, and is used for finishing forwarding and processing of a system control command and data forwarding; and the universal radio-frequency module is applied to receiving-transmitting and up / down conversion of radio-frequency signals and modulation and demodulation of baseband signals, and executing the control command issued by the system control management module. The universal interface system is applied to radio communication, navigation and monitoring systems. Through adoption of the universal interface system, the system integration testing amount can be reduced effectively, and the system stability is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a general interface of a multifunctional radio frequency module applied to a comprehensive radio communication, navigation and monitoring system.
