Detailed Description
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, 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 diagram illustrating one connection method of a KVM agent system according to an embodiment of the present invention. The KVM seat system mainly includes an access device, a switch device, and a management and control device, any two devices are interconnected by using an optical fiber/network cable, the optical fiber/network cable is used for transmitting a video code stream and an in-band signaling, all the devices realize video code stream transmission based on hardware and software, the commonly used hardware is an FPGA (Field Programmable Gate Array), and the commonly used software is an embedded software. The FPGA is used for realizing the exchange of video coding and decoding and video code streams and providing an in-band signaling channel for embedded software; the embedded software handles mainly in-band signaling.
It should be noted that the KVM seat system in fig. 1 is only an example, and the present invention is not limited to the KVM seat system in fig. 1, and may be a KVM seat system with other connection modes, which is not specifically limited herein.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a self-testing method of a KVM agent system according to an embodiment of the present invention, the method includes the following steps:
s10, based on the preset first check rule, checking whether the video code stream transmission among the devices in the KVM seat system is abnormal or not, and obtaining a first check result.
In order to detect whether transmission of a video code stream in each device of the KVM seat system is normal, in this embodiment, based on a preset first check rule, whether transmission of the video code stream between each device of the KVM seat system is abnormal is automatically checked, and a first check result is obtained. The first check result comprises that video code streams transmitted by all devices in the KVM seat system are consistent, video code streams transmitted by part of devices are inconsistent or video code streams transmitted by all devices are inconsistent. If the first verification result is that the video code streams transmitted by all the devices in the KVM seat system are consistent, the video code streams are normally transmitted in all the devices in the KVM seat system; if the first check result indicates that the video code streams transmitted by only part or all of the devices in the KVM seat system are inconsistent, it indicates that the transmission of the video code streams in each device of the KVM seat system is abnormal. Thus, in the embodiment, by checking the video stream of the KVM agent system, data check statistics and continuity statistics can be performed on the video stream.
Referring to fig. 3, in one embodiment, step S10 includes the following sub-steps:
s11, checking whether the video code stream transmitted by each device in the KVM seating system is accurate and continuous;
s12, if the video code stream transmitted by each device in the KVM seat system is accurate and continuous, the first verification result is that the video code stream is normally transmitted;
and S13, if the video code stream transmitted by each device in the KVM seating system is inaccurate and/or discontinuous, the first verification result is that the video code stream is transmitted abnormally.
In this embodiment, at the source of the video stream (i.e., the access device), the source data of each frame of the video stream is added with the check data and the frame number. The switching equipment detects the verification data of the received video code stream while exchanging data based on the ports, namely the accuracy and the continuity of the verification of the monitoring video code stream. The control equipment is responsible for decoding and displaying videos, and simultaneously monitors the check data and the frame continuity of the received code stream. Therefore, data check statistics and continuity statistics can be carried out on the video code stream in both the switching equipment and the control equipment.
Specifically, in step S11, the verifying whether the video code stream transmitted by each device in the KVM seat system is accurate and continuous includes: and checking whether the video code streams transmitted by the devices are complete and whether the frame serial numbers of the video code streams are continuous through the checking data of the video code streams transmitted by the switching device and the management and control device in the KVM seat system and the checking data of the access device.
If the video code stream transmitted by each device is verified to be complete and the frame sequence numbers of the video code streams are continuous through the verification data of the video code streams transmitted by the switching device and the management and control device in the KVM seat system and the verification data of the access device, the first verification result indicates that the video code streams are normally transmitted.
If the video code stream transmitted by each device is checked to be incomplete and/or the frame sequence number of the video code stream is not continuous through the check data of the video code stream transmitted by the switching device and the management and control device in the KVM seat system and the check data of the access device, the first check result is that the video code stream is abnormally transmitted.
And S20, based on a preset second check rule, checking whether the actual link connection relation of each device in the KVM agent system is consistent with the expected link connection relation, and obtaining a second check result.
In order to test whether the hardware connection and the link connection of each device in the KVM agent system are normal, in this embodiment, based on a preset second check rule, whether the actual link connection relationship and the expected link connection relationship of each device in the KVM agent system are consistent is automatically checked, and a second check result is obtained. In this way, the present embodiment can find out the link configuration packet loss or the link configuration error problem through the mutual inspection of the expected link and the real connection link.
Referring to fig. 4, in a specific embodiment, the KVM agent system includes a first device and a switch device, the first device includes a management device and/or an access device, and step S20 includes the following sub-steps:
s21, acquiring actual connection information of the first equipment; the actual connection information comprises equipment information of the first equipment and an actual link connection relation;
s22, obtaining the expected connection information of the exchange equipment; the expected connection information comprises device information of the first device and an expected link connection relationship;
s23, if the actual link connection relation of the first device is consistent with the expected link connection relation of the first device, the second check result is that the first device is normally connected;
s24, if the actual link connection relationship of the first device is inconsistent with the expected link connection relationship of the first device, determining that the connection of the first device is abnormal as a second check result.
In this embodiment, the actual connection information and the expected connection information of the first device may be obtained by in-band signaling. The actual connection information includes device information of the first device and an actual link connection relationship, the device information represents identification information and attribute information of the first device, and the actual link connection relationship reflects interconnection information of the first device and other devices.
In one embodiment, step S21 includes the following sub-steps:
acquiring an ID number of the first equipment timing broadcast;
and generating actual connection information of the first equipment based on the ID number broadcasted by the first equipment at regular time.
In terms of in-band signaling, the first device broadcasts the ID number of the corresponding device at regular time, so that the first device can detect the real device interconnected therewith. For example, the management and control device 1 and the management and control device 2 are interconnected, the management and control device 1 and the management and control device 3 are not interconnected, and the management and control device 1, the management and control device 2, and the management and control device 3 broadcast the corresponding ID numbers at regular time, so that the management and control device 1 can detect that the real device interconnected with the management and control device 1 is the management and control device 2 by broadcasting information mutually. At the same time, the switching device broadcasts the expected link connection relationship to all the first devices in the KVM agent system each time a link switch is made or a new connection is established.
Since the first device can directly acquire its actual connection information and acquire the expected connection information of the first device from the switching device, the verification process of step S20 can be performed in the first device, i.e., the first device verifies whether its actual link connection relationship is consistent with the expected link connection relationship.
In another embodiment, the switching device may also obtain the actual connection information of the first device from the first device, and therefore, the verification process of step S20 may also be performed in the switching device, which is not specifically limited herein.
Referring to fig. 5, in an embodiment, before the step S21 obtains the actual connection information of the first device, the step S10 checks whether the transmission of the video stream between the devices in the KVM agent system is abnormal based on a preset first check rule, and obtaining a first check result further includes the following steps:
s51, when the first device receives a link change instruction or exceeds a preset reporting time, determining whether an interface of the first device is abnormal;
s52, if the interface of the first device is confirmed to be abnormal, reporting abnormal data to the switching device;
s53, if the interface of the first device is confirmed to be normal, further confirming whether the actual link connection relation of the first device is abnormal;
and S54, if the actual link connection relation of the first equipment is confirmed to be abnormal, reporting abnormal data to the switching equipment.
In this embodiment, the transmission abnormality of the video code stream includes an accuracy check abnormality, a continuity check abnormality, or an optical fiber communication Physical link abnormality of the video code stream, and therefore, the FPGA of the first device can also count the optical port/network port communication abnormality through a bottom layer abnormality provided by an optical port/network port PHY (Physical layer), so as to identify the optical fiber/network cable abnormality or the optical module abnormality. Therefore, when the first device receives the link change instruction or exceeds the preset reporting time, whether the interface of the first device is abnormal or not is confirmed, if the interface is abnormal, the data with the abnormal interface is reported to the switching device, and then the FPGA stops timing counting; and if the link connection relation is normal, further confirming whether the actual link connection relation of the first equipment is abnormal. Therefore, the problem of the abnormality of the first equipment interface is conveniently positioned.
In order to realize the test function, a tester manually or a monitoring terminal automatically issues a link change instruction so as to change the actual connection information of the first device. When the first device receives the link change instruction and confirms that the interface of the first device is normal, whether the link connection relation of the first device is abnormal needs to be confirmed again, if the link connection relation is normal, the current connection relation is kept, and if the link connection relation is abnormal, abnormal data are reported to the exchange device.
In addition, by means of overtime triggering, when the time for the first device to report the abnormal data last time exceeds the preset reporting time, whether the actual link connection relationship of the first device is abnormal can be confirmed again.
Specifically, as shown in fig. 5, the FPGA of the first device has a function of timing counting, and when the time for the first device to report the abnormal data last time exceeds the preset reporting time, the FPGA triggers a process of reconfirming whether the actual link connection relationship of the first device is abnormal, if the actual link connection relationship is normal, the first device maintains the current connection relationship, and then the FPGA continues to count at regular time; and if the data is abnormal, the first equipment reports abnormal data to the exchange equipment, and then the FPGA stops timing counting. Through the function of timing counting, the abnormal data can be prevented from being reported too much, so that the normal operation of the whole KVM seat system is interfered under the condition that the fault of the individual first equipment occurs, and in addition, the load of the first equipment is lightened in order to reduce the frequency of detecting the abnormal data by the first equipment.
With continued reference to fig. 5, in one embodiment, the method further comprises the steps of:
s55, if the actual link connection relation of the first equipment is confirmed to be normal, further confirming whether the actual connection information of the first equipment is updated according to the link change instruction;
and S56, if yes, storing the updated actual connection information of the first device.
In this embodiment, when it is determined that the actual link connection relationship of the first device is normal, it is further determined whether the actual connection information of the first device is updated according to the link change instruction, and if so, the actual connection information is saved and the FPGA continues to count at regular time; if not, the actual connection information is not stored, and the FPGA continues to count at regular time. And when the timing of the FPGA exceeds the preset time, triggering the first device to execute the step S51 so as to confirm whether the interface of the first device is abnormal. In this way, the first device can save the normal actual connection information of the first device through the above steps.
The above embodiment describes in detail the processing flow of the exception detection and the exception reporting of the first device, and the following embodiment describes in detail the processing flow of the exception detection and the exception reporting of the switching device.
Referring to fig. 6, in a specific embodiment, the switching device is configured to connect to a monitoring terminal, and the step S22 of obtaining expected connection information of the switching device includes the following steps:
s61, confirming whether the test instruction sent by the monitoring terminal to the switching equipment is a link change instruction;
s62, if the test instruction is confirmed to be a link change instruction, further confirming whether the switching equipment configures a link corresponding to the link change instruction;
s63, if it is determined that the switch device does not configure the link corresponding to the link change instruction, configuring the corresponding link and updating the expected connection information of the switch device based on the link change instruction, and then broadcasting the updated expected connection information to the first device by the switch device.
In this embodiment, the monitoring terminal is connected to the switching device through a TCP/IP protocol, other than the KVM agent system, and is configured to configure and manage the client software of the entire KVM agent system. The monitoring terminal can send a test instruction to the switching device, where the test instruction includes a link change instruction or other instructions, and the link change instruction includes a new link/switch link instruction. It will be appreciated that the link change instructions define the links that need to be newly established/switched and the corresponding device information. Illustratively, taking a link change instruction as a link switching instruction as an example, for example, a link between the management and control device 1 and the management and control device 2 is switched to a link between the management and control device 1 and the management and control device 3; taking the link change instruction as a new link instruction as an example, for example, adding the management and control device 4, if the management and control device 1 and the management and control device 4 need to be interconnected, the link of the management and control device 1 and the management and control device 4 needs to be configured.
When the switching device receives the link change instruction, the switching device needs to further confirm whether the switching device configures a link corresponding to the link change instruction, if not, based on the link change instruction, a backplane switching link register is configured to configure a corresponding link and update expected connection information of the switching device, then the switching device broadcasts the updated expected connection information to all first devices, and the first devices can also refresh the expected connection information on their on-screen displays (OSD) so that the first devices can automatically judge the consistency of real connection and expected connection based on actual connection information and expected connection information.
With continued reference to fig. 6, in one embodiment, the method further includes the steps of:
s64, if the test instruction is not confirmed to be the link change instruction, further confirming whether the test instruction is abnormal data;
s65, if the test instruction is confirmed to be abnormal data, writing the abnormal data into a log and reporting the log to the monitoring terminal by the exchange equipment;
s66, if the test instruction is not confirmed to be abnormal data, further confirming whether the test instruction contains an abnormal log request;
and S67, if the test instruction contains an abnormal log request, summarizing the historical log and reporting the historical log to the monitoring terminal by the switching equipment.
In the embodiment of the invention, to realize the function of automatically reporting abnormal test data, when the test instruction received by the switching equipment is not a link change instruction, whether the test instruction is abnormal data needs to be further confirmed, if the test instruction is confirmed to be abnormal data, the abnormal data is counted and written into a LOG, and then the LOG is reported to the monitoring terminal by the switching equipment; if the test instruction does not contain the abnormal LOG request, as shown in fig. 6, it is further determined whether the test instruction contains the abnormal LOG request, if the test instruction contains the abnormal LOG request, the LOG data is organized and counted, and then the LOG data is reported to the monitoring terminal by the switching device, and if the test instruction does not contain the abnormal LOG request, the switching device does not need to report the LOG data to the monitoring terminal.
When the first device detects a link connection error or various abnormalities counted by the FPGA, the first device reports data to the switching device, the data reported by the first device and the data monitored by the switching device are summarized and counted on the switching device, and a tester can visually see whether the whole KVM seat system has the abnormality or not on the switching device. Therefore, by implementing the embodiment of the invention, the tester of the KVM seat system performs manual or automatic link configuration after completing interconnection of related equipment, and then can judge and check the first check result and the second check result through log software provided by the system, so as to judge whether the communication network of the system has problems or not, rather than observing through a large amount of eyes for a long time, the testing efficiency is high, and the research and development cost of a test product is reduced.
In addition, still improved the maintainability of KVM seat system at the user scene, promoted the on-the-spot problem location efficiency of product: after a field tester passes certain training, LOG LOG data can be roughly analyzed, and partial non-equipment quality BUG can be distinguished; meanwhile, field support testers can easily acquire relatively comprehensive LOG LOG data for analysis of background research and development personnel.
And S30, summarizing and outputting the first check result and the second check result.
After the first check result and the second check result are obtained, the switching equipment collects and outputs the first check result and the second check result, so that a tester can visually see whether the whole KVM seat system has abnormality or not on the switching equipment.
In other embodiments, the switching device may output the first verification result and the second verification result to the monitoring terminal, so that the tester can visually see whether there is an abnormality in the entire KVM seat system on the monitoring terminal.
In summary, by implementing the embodiment of the present invention, the KVM seat system has a test function, and specifically, based on a preset first check rule, it is checked whether video code stream transmission between devices in the KVM seat system is abnormal, so as to obtain a first check result; based on a preset second check rule, checking whether the actual link connection relation of each device in the KVM seat system is consistent with the expected link connection relation or not to obtain a second check result; and summarizing and outputting the first check result and the second check result. Therefore, the embodiment of the invention solves the product testing problems of multiple video matrix ports, multiple communication connection links, multiple modes of connection links, multiple use scenes and the like in the KVM seating system on one hand, releases testing personnel from a large amount of repeated test execution work and improves the testing efficiency; on the other hand, the maintainability of each device of the KVM seating system meeting the technical problems of related products when the device is used on the spot by a user is improved, and the on-spot problem positioning efficiency of the products is improved. In addition, problem location of the KVM seating system can be layered, and software designers organize and package scattered debugging information of bottom layer hardware/FPGA, namely, problem location ideas of the bottom layer hardware are arranged into software codes. When a product problem occurs, upper software personnel quickly analyze the probable cause of the problem and classify the problem, quickly identify the non-product quality problem and avoid the dilemma that all product developers must arrive at the site to solve once the product problem occurs.
