Description
Technical Field
The present application relates to the field of radio frequency testing technologies, and in particular, to a topology control method for a distributed dynamic radio frequency testing apparatus.
Background
With the development of wireless technology, the use of radio frequency technology in the fields of wireless communication, electronic countermeasure, radar and the like is more and more complex; further, more requirements of complexity and diversity are provided for radio frequency testing, and a radio frequency testing system is required to get rid of the dilemma of one module in the original scheme, and must have the capability of solving most of the existing radio frequency testing requirements. Each time the radio frequency test scheme is changed, almost a doubling of development cycle and cost results. In order to solve the problems of too long development period and too high research and development cost, the radio frequency test system must have a processing scheme for flexibly collocating different radio frequency functional modules, managing a global architecture and processing different test cases.
At present, a radio frequency test system generally uses passive devices, for example, basic devices such as an amplifier, a radio frequency switch, a step attenuator, a phase shifter, and the like to build a radio frequency link, so as to implement preprocessing of radio frequency signals, and the radio frequency signals are finally sent to equipment such as a signal source frequency spectrograph through a test circuit, thereby completing radio frequency testing. In the verification stage of the radio frequency test scheme, pure manual operation is usually adopted, each test case generates a radio frequency test requirement, a link structure needs to be designed, and the structure is manually built to complete test verification. With the increase of test cases, the complete manual operation brings a great deal of repeated labor. Therefore, it is common practice to design a theoretical design and verify by hand, then form an integrated automatic test scheme, and then implement an interface device according to the scheme. The device comprises all radio frequency devices of the verification scheme, a control circuit and embedded software; and the external part is connected with a tested part (DUT) and a test instrument, and a set of Automatic Test Equipment (ATE) is formed under the control of the upper computer software. In order to realize an interface device with a fixed structure and a fixed function, besides the purchase or self-manufacture of radio frequency components, a matched control module is required to be produced to compile corresponding embedded software. If a new radio frequency test requirement exists, the radio frequency signal link design needs to be carried out again, and the development of an interface device needs to be carried out again. At present, the construction of an interface device needs to rely on a large amount of experience of developing and designing radio frequency signal link simulation estimation, although the problem of requirement complexity and diversity improvement can be solved, the radio frequency module dominates the mode of constructing a test system, the function of each type of the interface device is fixed, and a control circuit and embedded software which are designed and developed for completing the function are also fixed; the limitations result in the need to redesign and produce the "interface device" for each new rf test requirement, which greatly increases the development cost and production cycle of the embedded software and control circuit part in the project development. Meanwhile, with the improvement of diversity and complexity of radio frequency test requirements, the complexity and cost of technical state management are also improved by the non-universal scheme.

s901 if the data information is direct control data, the main control board analyzes the data information and then directly sends the control data to a radio frequency module node through a CAN bus, and sets a processing mode to be mode 1, and the radio frequency module node sends the direct control data of the CAN bus to a radio frequency function module through an IO port; if the data information is not direct control data, the flow proceeds to step S902.
S902, if the data information is batch data control information, the main control board analyzes the data information and then sends the batch data control information to the radio frequency module node through the CAN bus, and sets the processing mode to be mode 2, wherein in the mode, the batch data control information CAN be directly stored in a storage area inside the single chip microcomputer; if not, the flow proceeds to step S903.
Optionally, the method may adopt one of two control modes to test the upper computer:
direct control mode (mode 1): the control mainboard directly sends control information to the radio frequency function module of the radio frequency module node through the bus, and directly performs link control. In this mode, the radio frequency module nodes such as the switch node, the attenuator node, the phase shifter node and the like directly transmit the control information in the received CAN information to the corresponding radio frequency element, which means that the control main board directly controls the IO port of each distributed radio frequency module node.
Storage trigger mode (mode 2): and the radio frequency module node stores the control information sent by the control mainboard through the bus, and synchronously executes link control under the condition of receiving the trigger signal sent by the control mainboard. Under the module, radio frequency module nodes such as a switch node, an attenuator node, a phase shifter node and the like can store multiple groups of data sent by a control mainboard in a storage area in advance, and when a trigger signal sent by the control mainboard is received, the radio frequency module node receiving the trigger signal synchronously executes one-time link control.
S903, if the data information is trigger control information, the main control board analyzes the data information to obtain the starting time, the ending time and the step length of sending a trigger signal, the sending rule of the trigger signal within a period of time is realized through a timer, the trigger signal is sent to a radio frequency module node through a CAN bus, and the control of a radio frequency function module is realized based on batch data control information stored in an internal storage area of a single chip microcomputer; if not, the process proceeds to step S800.
Optionally, the trigger signal may include: a soft trigger signal comprising a specific broadcast signal on the bus; and the hard trigger signal comprises a synchronous trigger signal sent by the signal enhancer of the control mainboard.
Fig. 10 is a schematic flow chart diagram of a distributed dynamic radio frequency testing method according to another embodiment of the present application. Correspondingly, the radio frequency module node is firstly powered on and started, receives bus information after various preparations of an IO port, a node ID and a bus are carried out, and carries out corresponding operation according to the type of data information sent by the bus. For example, in the direct control mode, after receiving the direct control information, the node directly sends the required data to the IO port of the node to complete the sending task. And in the trigger control mode, after receiving the batch data control information, the node stores the data into the storage area, and under the condition of receiving the trigger control information, the node takes out the data from the storage area and sends the data to an IO port of the node so as to complete a sending task.
It is to be understood that the data information is not limited to the above cases, and the steps are not necessarily executed in the above order.
The method integrates two data structures of a topological graph and a distributed node tree table of the radio frequency test interface device to dynamically construct software of the radio frequency test interface device, and provides a simple and friendly instruction system as a whole. The abnormal judgment and the alarm are carried out based on the node tree, so that the reliability of the radio frequency test is improved; the distributed system concept is adopted, and radio frequency testing basic function modules such as a radio frequency switch, a step attenuator, a phase shifter and the like are combined to complete a radio frequency testing function, so that the method has high universality and flexibility.
The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
