In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a multi-interface testing apparatus provided in the present invention, the apparatus includes:
a communication module 11;
the control module 12 is configured to receive an interface signal sent by the server through the communication module 11, and generate a control signal according to the interface signal, where the interface signal includes information of a current interface to be tested on the server, the server includes N interfaces to be tested, and N is an integer not less than 2;
the connector 13 comprises N connecting interfaces, and one ends of the N connecting interfaces are connected with the N interfaces to be tested one by one;
the selection module 14 is used for receiving a preset test signal sent by the server through the connection interface corresponding to the current interface to be tested when receiving the control signal, and sending the preset test signal to the test module 15;
the test module 15 connected to the second interface of the selection module 14 is configured to generate a first reply signal according to a preset test signal, and send the first reply signal to the server through the connection interface corresponding to the current interface to be tested, so that the server determines whether the current interface to be tested is normal according to the first reply signal.
In order to conveniently and quickly test whether the N interfaces to be tested on the server are normal, in the application, the selection module 14 and the connector 13 are firstly arranged, the connector 13 includes N connection interfaces, so as to be connected with the N interfaces to be tested on the server one by one, in actual work, the number of the interfaces to be tested on the servers in different styles is considered to be different, in order to be suitable for the servers in various styles, the connection interfaces included in the connector 13 can be larger than the number of the interfaces to be tested of the server, and the number of the connection interfaces in the connector 13 is not limited by the application. The other end of each connection interface is connected to each first interface of the selection module 14, so that a preset test signal sent by the server from any interface to be tested can be sent to the selection module 14 through the corresponding connection interface on the connector 13, so that the selection module 14 sends the preset test signal to the test module 15. Furthermore, the selection module 14 does not affect the communication protocol of the preset test signal, for example, when the sent preset test signal is the preset test signal of the I2C protocol, the selection module 14 can send the preset test signal of the I2C protocol to the test module 15.
In order to control the selection module 14 to select the connection interface corresponding to the current interface to be tested, a control module 12 and a communication module 11 are further provided, specifically, before the server sends the preset test signal, the server sends an interface signal to the communication module 11, the interface signal includes information of the current interface to be tested, after receiving the interface signal, the communication module 11 converts the interface signal into an interface signal in a format readable by the control module 12, and then sends the interface signal to the control module 12, and the control module 12 controls the selection module 14 to select the connection interface corresponding to the current interface to be tested according to the interface signal, so that the preset test signal can be sent to the test module 15 from the connection interface corresponding to the current interface to be tested. That is, before the server sends the preset test signal, the communication module 11 informs the control module 12 that the subsequent preset test signal will come from which interface to be tested, and then the control module 12 controls the selection module 14 to select the connection interface corresponding to the interface to be tested, so that when the preset test signal really comes, the connection interface corresponding to the current interface to be tested can be sent to the selection module 14, and then the connection interface corresponding to the current interface to be tested can be sent to the test module 15 from the selection module 14.
In order to enable the server to determine whether the current interface to be tested is normal, the test module 15 is provided, and the test module 15 can receive a preset test signal and generate a reply signal according to the preset test signal. Specifically, the preset test signal may be a signal corresponding to a certain instruction in the test module 15, the reply signal is a signal generated according to the signal of the instruction, and since a communication protocol of the preset test signal is related to the type of the interface to be tested of the server, in actual work, the test module 15 that is actually used needs to be selected according to the communication protocol of the preset test signal, for example, when the interface to be tested of the server is an I2C interface, the communication protocol of the preset test signal is an I2C protocol, and at this time, it may be determined that the test module 15 that needs to be used is the test module 15 that supports the I2C protocol; the preset test signal may be a signal for querying a model of the test module 15, when the test module 15 receives the signal for querying the model, a reply signal including the model of the test module 15 itself may be generated, then the test module 15 may send the reply signal to the server through the connection interface corresponding to the current interface to be tested, that is, the reply signal is sent to the server through the original path, after the server receives the reply signal, it may be determined whether the model of the test module 15 in the reply signal is consistent with the model of the preset test module 15, when consistent, the server determines that the current interface to be tested is normal, otherwise, it determines that the current interface to be tested is abnormal. In addition, before the server determines whether the model of the test module 15 in the reply signal is consistent with the preset model of the test module 15, the server may first determine whether the current interface to be tested is normal according to whether the reply signal is received within a preset time, if the reply signal is not received within the preset time, the current interface to be tested is determined to be abnormal, if the reply signal is received within the preset time, the server then performs the step of determining whether the model of the test module 15 in the reply signal is consistent with the preset model of the test module 15, and the method for the server to specifically determine the current interface to be tested is not limited in the present application.
In order to cooperate with the multi-interface test apparatus, a test script for each interface to be tested may be set in the server, and may be, for example, the following test script: the server firstly determines the number of interfaces to be tested which are communicated with corresponding connection interfaces in each interface to be tested, determines the test sequence of each interface to be tested according to a preset interface sequencing mode when the number is consistent, then takes the first interface to be tested as the current interface to be tested, generates an interface signal containing the information of the current interface to be tested, sends the interface signal to the communication module 11, generates a preset test signal, sends the preset test signal to the test module 15 through the connection interface corresponding to the current interface to be tested, and then judges whether the current interface to be tested is normal or not based on a reply signal generated by the test module 15; then, if the current interface to be tested is not the last interface to be tested in the preset interface sequence to be tested, taking the next interface to be tested of the current interface to be tested as a new interface to be tested, and returning to the step of generating an interface signal containing the information of the current interface to be tested and sending the interface signal to the communication module 11 until the current interface to be tested is the last interface to be tested; and finally, generating a log containing the test result of each interface to be tested, the preset test signal of each interface to be tested and the corresponding reply signal so that a worker can check the test result of each interface to be tested. In addition, the method and the device for judging whether the current interface to be tested is the last interface to be tested are not limited by the server.
In summary, by providing the communication module 11, the control module 12, the selection module 14, the test module 15, and the connector 13 having N connection interfaces, where the N connection interfaces are connected to the N interfaces to be tested on the server one by one, when the control module 12 receives an interface signal including a current interface to be tested and sent by the server through the communication module 11, the control module can generate a corresponding control signal and send the control signal to the selection module 14, when the selection module 14 receives the control signal, the selection module 14 can send a preset test signal sent by the server through the connection interface corresponding to the current interface to be tested to the test module 15, when the test module 15 receives the preset test signal, the test module 15 can generate a corresponding reply signal and send the reply signal to the server through the connection interface corresponding to the current interface to be tested, so that the server determines whether the current interface to be tested is normal, when the interface to be tested of the server is the I2C interface, a plurality of even all I2C interfaces on the server can be connected to the connector 13 at the same time, that is, the testing of all I2C interfaces on the server can be completed by using one multi-interface testing device, the testing process of a plurality of I2C interfaces is simplified, manual dismantling and installation for many times are not needed, and the application range is expanded.
On the basis of the above-described embodiment:
as a preferred embodiment, the control module 12 is further configured to determine, when the N connection interfaces are connected to the N interfaces to be tested one by one, an overturning number of a connection interface whose level is overturned in the N connection interfaces, and send the overturning number to the server, so that the server enters the step of sending the interface signal when determining that the overturning number is equal to the preset number of the interfaces to be tested.
Because each interface to be tested on the server is connected with each connection interface one by one, when the number of the interfaces to be tested which are communicated with the corresponding connection interfaces in each interface to be tested is less than the number of the interfaces to be tested which are preset on the server, the fact that the interfaces to be tested are abnormal exists is considered, for example, when the wire rod between the interface to be tested and the corresponding connection interface is broken or the interface is short-circuited, the communication between the interface to be tested and the corresponding connection interface can not be achieved. In order to determine the number of the communicated interfaces to be tested, in the application, when each connection interface is connected with each interface to be tested one by one, the server sends a level signal to the corresponding connection interface from each interface to be tested, so that the level of each connection interface is inverted at the moment, for example, when the connection interface is not connected with the interface to be tested, the level of the connection interface is a low level, and when the connection interface is connected with the interface to be tested, the level of the connection interface is inverted into a high level. Because the level of the connection interface is turned over to indicate that the connection interface and the interface to be tested are normally communicated at the moment, the control module 12 can determine the number of the connection interfaces with the level turned over in each connection interface, namely the turning number, and then sends the turning number to the server, when the server receives the turning number, the server judges whether the turning number is consistent with the preset number of the interfaces to be tested, when the turning number is consistent, the step of sending an interface signal is started, when the turning number is inconsistent, a worker can be prompted to find the specific unconnected interface to be tested, so that the worker can repair the unconnected interface to be tested, and the method does not limit the subsequent steps when the turning number is inconsistent.
As a preferred embodiment, the selection module 14 is specifically configured to control the connection interface corresponding to the current interface to be tested to be connected with the test module 15 when receiving the control signal, and control each connection interface except the connection interface corresponding to the current interface to be tested to be disconnected from the test module 15.
In order to avoid that a plurality of preset test signals are sent to the test module 15 through the connection interfaces corresponding to the plurality of interfaces to be tested at the same time, and logic confusion is caused by the fact that the test module 15 receives the plurality of preset test signals, in the present application, the selection module 14, after receiving the control signal corresponding to the interface signal, controls the connection between the connection interface corresponding to the current interface to be tested and the test module 15, and disconnects other connection interfaces from the test module 15, which is equivalent to that in each connection interface at this time, only the connection interface corresponding to the current interface to be tested can transmit the preset test signal to the test module 15, and the selection function realized by the selection module 14 can be regarded as being basically the same as the function of the multiplexer. In addition, the selection module 14 may keep the connection interface corresponding to the current interface to be tested and the test module 15 to be connected after receiving one control signal until receiving the next control signal. Because the selection module 14 can only allow one connection interface to be connected with the test module 15, the situation that a plurality of preset test signals are sent to the test module 15 through the connection interfaces corresponding to the plurality of interfaces to be tested at the same time is avoided, and the situation that the test module 15 generates logic confusion due to the fact that the plurality of preset test signals are received is further avoided.
As a preferred embodiment, the communication module 11 includes:
one end of the USB connecting interface is connected with the USB interface of the server;
the USB-to-UART module, of which the input end is connected to the other end of the USB connection interface and the output end is connected to the control module 12, is configured to receive the interface signal through the USB connection interface, convert the interface signal into an interface signal in the UART format, and send the interface signal in the UART format to the control module 12.
In order to flexibly receive an interface signal sent by a server, in the present application, please refer to fig. 2, fig. 2 is a schematic structural diagram of another multi-interface testing apparatus provided by the present invention, in consideration that substantially all servers are provided with USB (Universal Serial Bus) interfaces, instructions of the servers can be transmitted to other devices linked to the USB interfaces through the USB interfaces, and since the USB interfaces support hot plug functions and have advantages of small interface volume, convenient plugging and unplugging, and small circuit area, a USB connector 13 and a USB to UART (Universal Asynchronous Receiver/Transmitter) module are provided in a communication module 11, one end of the USB connector 13 is connected to the USB interface on the server, the other end is connected to the USB to UART module, the interface signal sent by the server enters the USB to module through the USB interface first, the USB to UART module converts the interface signal in the USB format into an interface signal in the UART format, and finally sends the interface signal to the control module 12. The selection module 14 not only can flexibly receive the interface signal sent by the server, but also can transmit the interface signal to the control module 12 faster through the UART, with a faster data transmission speed, usually 1Mbps per second.
In a preferred embodiment, the control module 12 is an MCU.
In order to simply implement the function of the Control module 12, in the present application, the Control module 12 is an MCU (Micro Control Unit), which is a highly integrated chip, and not only has a small circuit area and simple development, but also has a lower cost compared to a CPU (Central Processing Unit), and can implement the function of the Control module 12, that is, the function of generating a corresponding Control signal according to an interface instruction and sending the Control signal to the selection module 14. The MCU is adopted as the control module 12, and the function of the control module 12 can be simply realized.
As a preferred embodiment, further comprising:
and the power supply module is used for supplying power to the communication module 11, the control module 12, the selection module 14 and the test module 15.
Considering that the communication module 11, the control module 12, the selection module 14 and the test module 15 all need to supply power, in the present application, a power module is further provided, since these modules all need to be supplied with power to operate normally, if the modules are connected to the power supply interfaces corresponding to the respective modules through external power equipment to supply power to the modules, not only additional interfaces and wires are needed, but also the modules may not realize normal functions because the voltage of the external power equipment is different from the voltage needed by the respective modules, and even the modules may be burned out because the voltage of the external power equipment is too large, one power module may be provided to be connected with other modules one by one, specifically, the power module may determine the magnitude of the operating voltage needed by the respective modules in advance, and then determine the voltage value of the power module according to the required operating voltage, so that the power supply voltage of the power module can be consistent with the voltage needed by the respective modules, the power supply module can not be burnt down due to overlarge voltage, and in addition, the power supply module can be provided with interfaces for outputting different voltages so as to be connected with each module more flexibly.
As a preferred embodiment, the power module is a rechargeable battery.
In order to recycle the power module, the power module is a rechargeable battery in the application, and the rechargeable battery can be put into use again only after being charged for a period of time after consuming electric quantity, so that a new battery is not required to be replaced, the power module can be recycled, and environmental pollution caused by frequent replacement of the new battery is avoided. In consideration of the practicability in actual work, the power supply interface of the rechargeable battery can be connected with the power supply interface on the server, such as a USB interface, so that the power supply module can be charged while the interface to be tested of the server is tested, and the cruising ability and the practicability of the power supply module are improved.
As a preferred embodiment, when there is an external test device connected to the selection module 14, the selection module 14 is further configured to send a preset test signal to the external test device through a connection interface corresponding to the current interface to be tested when receiving the control signal, so that the external test device generates a second reply signal according to the preset test signal, and sends the second reply signal to the server through the connection interface corresponding to the current interface to be tested, and the server determines whether the current interface to be tested is normal according to the second reply signal.
In order to flexibly receive the preset test signal, in the present application, the selection module 14 may also be connected to an external test device, when the external test device is connected with the selection module 14, when receiving the preset test signal, sends the preset test signal to the test module 15 through the connection interface corresponding to the current interface to be tested, and also sends the preset test signal to the external test device through the connection interface corresponding to the current interface to be tested, so that the external test device generates a second reply signal according to the preset test signal, and then, the second reply signal is sent to the server through the connection interface corresponding to the current interface to be tested, that is, the server can not only judge whether the current interface to be tested is normal according to the reply signal generated by the test module 15, but also judge whether the current interface to be tested is normal according to the reply signal generated by the external test device. Specifically, the type of the external test device may be adapted to vary according to the type of the actual Interface to be tested, and the external test device may be any device capable of presetting a test signal to generate the second reply signal, for example, when the type of the Interface to be tested is an I2C Interface, the external test device may be an I2C dedicated test fixture, a hard disk backplane, or another test device supporting an I2C protocol, and may generate the second reply signal according to a preset test signal of the I2C protocol, such as an IPMI (Intelligent Platform Management Interface) related signal. In practical situations, when the test module 15 is damaged, the server can still determine whether the current interface to be tested is normal according to the second reply signal sent by the external test device due to the connection of the external test device, and can more flexibly receive the preset test signal. In addition, because external testing arrangement is comparatively diversified, can receive the test signal of predetermineeing that other test module 15 can not receive, can make the test range of server to the test of interface that awaits measuring wider.
