[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] The signal debugging adapter module is mainly used to implement the interface adaptation of the test host and the interface adaptation and position fixation of the resident board 2 to be tested. The signal debugging adapter module serves as a bridge connecting the test host and the resident board 2 to be tested, and its purpose is to adapt and convert the electrical and data bus interfaces between the two. The signal debugging adapter module of this application adopts a connector to be connected to the test host through a test cable, and is finally connected to the bus board inside the test host to complete the adaptation of the test host end. In addition, according to the user's test system requirements, the test system needs to include a signal debugging adapter module, which transparently transmits the data of the resident board 2 to be tested to the test host, and during the bus drive test process, burns the use case and control program to the resident board 2 to be tested. Therefore, the test cable connected in this application includes a first test cable and a second test cable in addition to the bus cable. Among them, the first test cable is an Ethernet interface cable, which is used to connect the network port 11 on the debug board in the signal debugging adapter module of this application and the debugging network port on the test host; the second test cable is an RS232 serial port cable, which is used to connect the serial port 7 on the debug board in the signal debugging adapter module of this application and the debugging serial port on the test host. This application is connected to the test host through the RS232 serial port 7 or the network port 11, and can realize program burning, data communication and test control. That is, the user can perform data communication and program burning and downloading on the resident board 2 to be tested through the host computer program of the test host and the serial port 7, the network port 11 or the separately set download port 10, and can also control the test process, thereby increasing the flexibility of the signal debugging adapter module.
[0024] This application discusses the signal debugging adapter module provided in this application from four major aspects: signal debugging adapter module composition, signal debugging adapter module function design, signal debugging adapter module power supply design and signal debugging adapter module interface adaptation design.
[0025] (I) Composition of signal debugging and switching module.
[0026] like Figure 1As shown, the signal debugging adapter module disclosed in the present application is mainly composed of a shell structure 12 and a debugging board, an interface adapter board 1, a connector, a switch 3, a power signal indicator light 5, a power test interface 4, a first power module (switching power supply) and a plurality of fans 6 arranged in the shell structure 12. The debugging board and the interface adapter board 1 are core components of the signal debugging adapter module of the present application. The switch 3 is connected to the first power module and is used to control the power-on state of the first power module. Among them, the debugging board is equipped with a secondary power module composed of a plurality of DC-DC modules. The signal debugging adapter module supplies power to the resident board 2 to be tested through the secondary power module while integrating the test host resources and performing signal conditioning. Specifically, the debugging board includes a secondary power module and a connector. The input end of the secondary power module is connected to an external input power supply, and the secondary power module is used to output power supply signals of multiple specifications. One end of the connector, i.e. Figure 1 The bus interface of the debugging board part is connected to the card connector of the debugging board, and the other end is connected to the bus interface of the test host through a bus cable. The debugging board receives the bus signal of the test host through a connector and performs interface adaptation. The operating system controller in the test host is a CPU, and the bus board is used to communicate with the product. The input end of the first power module of the present application is connected to the distribution cabinet for converting AC power into DC power. Since the output of the distribution cabinet of the present application is 220V AC power, the first power module in the signal debugging adapter module is connected to the distribution cabinet through a 220V power supply interface 8, then the first power module is used to convert the external input 220V AC power into 36V DC power, and the output end of the first power module is connected to the input end of the secondary power module through a 36V socket. Subsequently, the present application converts the 36V DC power into 28V, 15V, 12V and 5V DC respectively through the built-in secondary power module of the debugging board, and obtains power supply signals of different specifications, and finally distributes these signals to the resident board 2 to be tested through the interface adapter board 1, and forms a complete physical connection path in sequence. Specifically, the output end of the secondary power module and one end of the connector are connected to the interface adapter board 1 through a board-level rectangular connector, and the signal debugging adapter module is connected to the resident board 2 to be tested through the interface adapter board 1. In addition, the power signal indicator light 5 is an LED light, which serves as a normal power indicator. Normal display indicates that the power is normal; the power test interface 4 is used for external power detection; the shell structure 12 is used to integrate each module and the fan 6, and the fan 6 is connected to the debugging board through the socket on the debugging board. The signal debugging adapter module has a built-in control circuit to realize multi-channel power detection control, and at the same time controls multiple fans 6 inside the signal debugging module to dissipate heat for the debugging board.
[0027] (2) Functional design of signal debugging and switching module.
[0028] like Figures 1 to 3As shown, the debugging board is the main component of the signal debugging adapter module of the present application. The debugging board integrates all the signals provided by the test host and combines with the internally converted power interface, so that the entire signal debugging adapter module of the present application provides all the resources to the resident board 2 to be tested, including the hardware interface: supporting the LED indication function of power supply 28VDC, 15VDC, 12VDC and 5VDC, and using the banana socket test hole as the reserved power test interface 4; the rear panel of the signal debugging adapter module of the present application has the functions of network port 11 and RS232 serial port 7, which can realize the functions of program burning, data communication and test control with the resident board 2 to be tested.
[0029] The connector connects all signals of the test host through the signal interface 9, redistributes the signals through the signal debugging adapter module, and transfers the signals to the corresponding resident board 2 to be tested through different interface adapter boards 1. In addition, the interface adapter board 1 supports locking and plug-in functions; the shell structure 12 has a handle and a footrest for easy carrying and placement; the color of the shell structure 12 can be defined by the user; the connector uses high-quality aviation-grade products to ensure reliable signal transmission.
[0030] (3) Signal debugging adapter module power supply design.
[0031] The overall power supply of the signal debugging adapter module is set according to the 220VAC / 50H input voltage. As a specific embodiment, the signal debugging adapter module of the present application is powered by standard AC220V / 50HZ, and is connected to the power supply using a herringbone power connector, meeting the standard requirements of a universal 10A socket. After the signal debugging adapter module connects the external AC220V / 50HZ, it is converted by the first power module to obtain a 36V DC power supply, which is then converted by a secondary power module composed of multiple DC-DC modules to form four power outputs such as 5VDC, 12VDC, 15VDC, and 28VDC. Specifically, the secondary power supply module includes a first DC-DC module, a second DC-DC module, a third DC-DC module and a fourth DC-DC module, and the input ends of the first DC-DC module, the second DC-DC module, the third DC-DC module and the fourth DC-DC module are all connected to the output end of the first power supply module; the output ends of the first DC-DC module, the second DC-DC module, the third DC-DC module and the fourth DC-DC module are all connected to the interface adapter board 1 through a board-level rectangular connector.
[0032] The DC-DC modules on the signal debugging adapter module uniformly use 36VDC as the input voltage for power conversion, which avoids passive failure of other power supplies when a power supply fails. At the same time, each power supply is designed with a power signal indicator 5 and a power test interface 4, which is convenient for the operator to visually detect the status of each power supply from the outside, and the power supply test can be completed without disassembling the machine when a failure occurs. Specifically, multiple power signal indicator lights 5 are connected to the first DC-DC module, the second DC-DC module, the third DC-DC module, and the fourth DC-DC module in a one-to-one correspondence to display whether the power supplies of 28VDC, 15VDC, 12VDC, and 5VDC are working normally; multiple power test interfaces 4 are connected to the first DC-DC module, the second DC-DC module, the third DC-DC module, and the fourth DC-DC module in a one-to-one correspondence to respectively detect the power supply voltage of the first DC-DC module, the second DC-DC module, the third DC-DC module, and the fourth DC-DC module.
[0033] (IV) Signal debugging adapter module interface adaptation design.
[0034] The signal debugging switching module of the present application is composed of a debugging board and an interface adapter board 1, and the design scheme of the two boards is as follows.
[0035] Debug board: In the signal debugging adapter module, the main function of the debugging board is to integrate various bus communication signals as well as serial and network port signals from the test host. At the same time, it powers the resident board 2 to be tested and the entire signal debugging adapter module. The debugging board converts 220V AC into 36V DC through the first power module. Four DC-DC modules are provided on the debugging board to provide 4 different voltage inputs for the resident board 2 to be tested, and to power the signal debugging adapter module as a whole. In order to facilitate power status monitoring, the interface adapter motherboard has 4 power signal indicator lights 5 and 4-way power test interfaces 4. The debugging board organizes all bus signals, serial and network port signals, and power supply voltage signals on the board into a large board-level rectangular connector. The board-level rectangular connector integrates the interface resources of the entire test environment and is connected to the interface adapter board 1.
[0036] Interface adapter board 1: In the signal debugging and switching module, the main function of the interface adapter board 1 is to adapt to various different resident boards 2 to be tested. As the middleware between the debugging board and the resident board 2 to be tested, the interface resources such as the bus signal, serial port signal, network port signal and power supply signal generated by the debugging board integrated on the debugging board are classified and allocated to the resident board 2 to be tested as needed, and finally the transparent transmission between the resident board 2 to be tested and the test host is realized. Since there are many kinds of resident boards 2 to be tested and the interface forms vary greatly, the interface adapter board 1 that matches it one by one is designed according to different resident boards 2 to be tested. The function of the interface adapter board 1 is interface conversion, which converts different connectors into the same connector, plugs it into the debugging board, and completes the adaptation of the physical interface.
[0037] The signal debugging adapter module of the present application has a free and rich connection mode, supports the test host interface corresponding to each type of resident board and the signal switching in various test scenarios, and provides a variety of power supply voltage options for the resident board 2 to be tested. The signal debugging adapter module of the present application is also scalable, and can adapt to the resident board 2 to be tested of a new type and a new interface by developing a new interface adapter board 1, which can be achieved by ensuring that the connector type and signal definition on the debugging board side are the same.
[0038] The test host is connected to the signal debugging adapter module through a customized bus cable, serial port 7 and network port 11. The power distribution cabinet supplies power to the debugging adapter module through a triangle socket. The resident board 2 to be tested is plugged into the interface adapter board 1 of the signal debugging adapter module through a board-level rectangular connector. The interface adapter board 1 is buckled onto the debugging board through a buckle board connector.
[0039] In summary, the signal debugging adapter module of the present application is mainly composed of a debugging board, an interface adapter board 1, a first power supply module, a switch 3, a fan 6, a connector and other components, which can realize the interface adaptation and power supply of the resident board 2 to be tested, and transmit the adapted signal to the test host, and at the same time, burn the version of the resident board 2 to be tested through the serial port 7 and the network port 11 on the debugging board. Among them, the signal transmitted between the debugging board and the interface adapter board 1 is a full coverage of all resources of the test host. After passing through the interface adapter board 1, part of the signal is adapted to different models of resident boards 2 to be tested, thereby completing the adaptation function of the electrical signal. The resident board 2 to be tested is also provided with an LC optical port interface and an LRM connector interface. The LRM connector interface is connected to the interface adapter connector in the interface adapter board 1, and the LC optical port interface and the LRM connector interface are respectively used to connect to the test host and the debugging adapter module.
[0040] Compared with the existing signal debugging adapter module, the signal debugging adapter module of the present application has the following advantages.
[0041] 1. The signal debugging adapter module of this application has strong adaptability. By combining the debugging board and the interface adapter board 1, the flexibility and versatility of the signal debugging adapter module are enhanced. If the bus board is within the range of the test host, only a simple interface adapter board 1 needs to be developed to carry out the test, avoiding the need to rebuild the test environment and saving a lot of time. If the test board is not within the range of the test host, only the corresponding test board needs to be added to the test host, and then the signal of the newly added test board is connected to the reserved serial port 7 or network port 11 of the signal debugging adapter module of this application to test the newly added signal, thus avoiding duplication of work and improving the efficiency of environment construction.
[0042] 2. The signal debugging adapter module of this application is easy to use and has its own power distribution function. The external power supply of the signal debugging adapter module of this application only needs 220V AC power to complete the power supply of the signal debugging adapter module and the resident board 2 to be tested. The signal debugging adapter module of this application is equipped with a rich power conversion circuit inside, providing a variety of power supply solutions for the resident board 2 to be tested.
[0043] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
