Description

Technical Field

[0001] This application relates to the technical field of communication quality testing, and in particular to a method, apparatus, device and storage medium for testing the communication quality of two machines. Background Technology

[0002] In embedded systems fields such as smart homes and industrial control, the reliability of dual-machine communication is crucial to ensuring stable system operation; therefore, it is essential to conduct thorough and effective testing of the quality of dual-machine communication during production testing and R&D verification.

[0003] Currently, the quality of communication between two devices is mostly tested manually. For example, the tester triggers a specific action on one end of the device, such as controlling the motor to rise and fall simultaneously, and observes whether the other end of the device can respond synchronously, in order to determine whether the communication data packets are lost.

[0004] However, this testing method, which relies on manual triggering and visual observation, has obvious limitations: First, for a large amount of test data, this method requires a lot of manpower and time, making it difficult to conduct long-term continuous testing and resulting in low testing efficiency; second, human judgment is subjective and prone to error, and cannot guarantee testing accuracy. Summary of the Invention

[0005] This application provides a method, apparatus, device, and storage medium for dual-machine communication quality testing, which can realize automated dual-machine communication quality testing and significantly improve testing efficiency and accuracy.

[0006] In a first aspect, this application provides a method for detecting the quality of dual-device communication, applied to a communication system including a first device and a second device, comprising: after the first device and the second device complete a handshake operation, initializing a plurality of first counters in the first device and controlling the first device to send a test command to the second device; dynamically updating the first count values ​​corresponding to the plurality of first counters based on whether the first device receives response data returned by the second device within a preset time; evaluating the communication quality between the first device and the second device based on the updated first count values, and outputting a communication quality result.

[0007] In one possible implementation, the plurality of first counters includes a first transmit counter, a first receive counter, a first retransmit counter, and a first failure counter.

[0008] In one possible implementation, initializing the plurality of first counters in the first device specifically includes: setting the first transmission count value corresponding to the first transmission counter, the first reception count value corresponding to the first reception counter, the first retransmission count value corresponding to the first retransmission counter, and the first failure count value corresponding to the first failure counter to zero, respectively.

[0009] In one possible implementation, controlling the first device to send a test command to the second device specifically includes: detecting whether the current first receive count value corresponding to the first receive counter is greater than a preset threshold; if so, incrementing the first send count value corresponding to the first send counter to obtain an updated first send count value, and obtaining the current first send count value of the first send counter and the current first receive count value of the first receive counter; otherwise, directly obtaining the current first send count value of the first send counter and the current first receive count value of the first receive counter; constructing a test command based on the current first send count value and the current first receive count value, and sending the test command to the second device.

[0010] In one possible implementation, the first count value corresponding to the plurality of first counters is dynamically updated based on whether the first device receives response data returned by the second device within a preset time. Specifically, this includes: starting a timeout timer after the first device sends a test command to the second device; if the first device does not receive response data returned by the second device within the preset time, decrementing the instruction count value corresponding to the instruction counter to obtain an updated instruction count value; performing an update operation on the first count value corresponding to the plurality of first counters based on the updated instruction count value, wherein the instruction count value corresponding to the instruction counter is updated to a preset maximum instruction count value when the first device first sends a test command to the second device within a single test command sending cycle; and dynamically updating the first count value corresponding to the plurality of first counters based on the response data if the first device receives response data returned by the second device within the preset time.

[0011] In one possible implementation, based on the updated instruction count value, an update operation is performed on the first count values ​​corresponding to the plurality of first counters. Specifically, this includes: comparing the updated instruction count value with a preset target value; if the updated instruction count value is not the preset target value, controlling the first device to resend the test instruction to the second device, and incrementing the first retransmission count value corresponding to the first retransmission counter; if the updated instruction count value is the preset target value, and the current first transmission count value of the first transmission counter is greater than the preset target value, then incrementing the first failure count value corresponding to the first failure counter, and controlling the first device to resend the test instruction to the second device.

[0012] In one possible implementation, after the first device and the second device complete the handshake operation, the method further includes: initializing a plurality of second counters in the second device; after the second device receives the test instruction sent by the first device, updating the second count values ​​corresponding to the plurality of second counters based on the test instruction; generating response data corresponding to the test instruction based on the updated second count values, and controlling the second device to send the response data to the first device.

[0013] In one possible implementation, the plurality of second counters includes a second transmit counter and a second receive counter.

[0014] In one possible implementation, updating the second count value corresponding to the plurality of second counters based on the test instruction specifically includes: the plurality of second counters includes a second transmit counter and a second receive counter; obtaining the current first transmit count value carried in the test instruction; if the current first transmit count value is zero, then initializing the second receive count value corresponding to the second receive counter; if the current first transmit count value is not zero, and the current first transmit count value is not equal to the second transmit count value corresponding to the second transmit counter, then updating the second receive count value corresponding to the second receive counter, and updating the second transmit count value to the current first transmit count value.

[0015] Secondly, this application provides a dual-device communication quality detection device, applied to a communication system including a first device and a second device, comprising: a test command sending module, a first value updating module, and a communication quality evaluation module; wherein, the test command sending module is used to initialize a plurality of first counters in the first device and control the first device to send test commands to the second device after the first device and the second device complete a handshake operation; the first value updating module is used to dynamically update the first count values ​​corresponding to the plurality of first counters based on whether the first device receives response data returned by the second device within a preset time; the communication quality evaluation module is used to evaluate the communication quality between the first device and the second device based on the updated first count values ​​and output the communication quality result.

[0016] Thirdly, embodiments of this application also provide a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the above-described method.

[0017] Fourthly, embodiments of this application also provide a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the above-described method.

[0018] This application provides a method, apparatus, device, and storage medium for detecting the quality of dual-machine communication, which has the following advantages compared with the prior art:

[0019] This method initializes multiple first counters in the first device after the first device and the second device complete a handshake operation, and controls the first device to send a test command to the second device. Based on whether the first device receives response data from the second device within a preset time, the method dynamically updates the first count values ​​corresponding to the multiple first counters. Based on the updated first count values, the method evaluates the communication quality between the first device and the second device and outputs the communication quality result. Compared with existing technical solutions, this application's technical solution initializes multiple first counters in the first device, sends a test command to the second device, and dynamically updates the count values ​​of the multiple first counters based on whether response data is received within a preset time, thereby quantitatively evaluating the communication quality. This method replaces the traditional manual triggering and visual observation methods, enabling long-term, continuous testing without manual intervention, greatly reducing manpower and time costs, and significantly improving testing efficiency. Simultaneously, based on the count values ​​of the first counters, it avoids subjective judgment errors and can accurately capture issues such as packet loss during communication, outputting reliable communication quality results.

[0032] Example 1, see Figure 1 , Figure 1 This is a flowchart illustrating one embodiment of a dual-machine communication quality detection method provided in this application, as shown below. Figure 1 As shown, this method is applied to a communication system including a first device and a second device, and includes steps 101-103, as detailed below:

[0033] Step 101: After the first device and the second device complete the handshake operation, initialize multiple first counters in the first device and control the first device to send test commands to the second device.

[0034] In one embodiment, the first device is a master device and the second device is a slave device.

[0035] In one embodiment, the handshake operation between the first device and the second device can be implemented through a request-response mechanism.

[0036] Specifically, the handshake operation is initiated by the first device sending a handshake request instruction to the second device, and the first device starts a handshake timeout timer for a first preset duration after sending the handshake request instruction; if the first device receives a handshake response instruction corresponding to the handshake request instruction from the second device before the handshake timeout timer reaches the first preset duration, the handshake operation is determined to be successful; otherwise, the handshake operation is determined to be unsuccessful.

[0037] Specifically, the handshake operation between the first and second devices establishes a reliable communication foundation for subsequent automated testing of communication quality, ensuring that both devices are in a responsive and ready state, thus avoiding the waste of resources caused by blindly sending test commands before the communication link is established.

[0038] In one embodiment, the plurality of first counters includes a first transmit counter, a first receive counter, a first retransmit counter, and a first failure counter.

[0039] Specifically, the first transmit counter is used to count the total number of test commands effectively sent by the first device to the second device; the first receive counter is used to count the number of times the first device successfully receives response data from the second device; the first retransmit counter is used to count the number of times the first device retransmits test commands because it does not receive a response in time; and the first failure counter is used to count the number of test commands that the first device still fails to receive a response after the maximum number of retries.

[0040] In one embodiment, initializing the plurality of first counters in the first device specifically includes: setting the first transmission count value corresponding to the first transmission counter, the first reception count value corresponding to the first reception counter, the first retransmission count value corresponding to the first retransmission counter, and the first failure count value corresponding to the first failure counter to zero, respectively.

[0041] Specifically, during the initialization phase, the count values ​​of the first transmit counter, the first receive counter, the first retransmit counter, and the first failure counter are reset to zero. This ensures that there is no historical data interference before the test begins, allowing the first transmit counter to start recording the number of command transmissions from zero, thus avoiding the influence of past transmission records on the current test data. The first receive counter starts counting valid responses from zero. Resetting the first retransmit counter and the first failure counter to zero can accurately count the actual number of data packet retransmissions and communication failures in this test, providing reliable raw data for subsequent evaluation of communication quality.

[0042] In one embodiment, controlling the first device to send a test command to the second device specifically includes: detecting whether the current first receive count value corresponding to the first receive counter is greater than a preset threshold; if so, incrementing the first send count value corresponding to the first send counter to obtain an updated first send count value, and obtaining the current first send count value of the first send counter and the current first receive count value of the first receive counter; otherwise, directly obtaining the current first send count value of the first send counter and the current first receive count value of the first receive counter; constructing a test command based on the current first send count value and the current first receive count value, and sending the test command to the second device.

[0043] Specifically, the preset threshold is 0.

[0044] Specifically, if the current first receive count value corresponding to the first receive counter is not greater than a preset threshold, it indicates that no effective communication has yet occurred between the first device and the second device. In this case, directly obtaining the current first send count value and the current first receive count value is to start communication from the baseline state. For example, when sending for the first time, the first send count value is 0 and the first receive count value is 0. After receiving the test command, the second device will recognize it as the initial test command and initialize its own second counter accordingly, establishing a unified counting starting point for subsequent communication. If the first send count value is incremented at this time, it may cause confusion in the second device's counting of the initial test command, which may hinder the establishment of the first communication.

[0045] Specifically, if the current first receive count value corresponding to the first receive counter is detected to be greater than a preset threshold, it indicates that the first device has successfully received response data returned by the second device at least once. In this case, the first send count value is incremented to generate a new instruction. The second device will compare the first send count value recorded in its previous processing with the current first send count value in the current test instruction to determine whether it is a new test instruction. If the increment is not performed, the new test instruction will carry the same current first send count value as the previous instruction. The second device may misjudge it as a duplicate old test instruction, resulting in no response or an incorrect response. After incrementing, the updated current first send count value and the current first receive count value can ensure that the data carried in the new test instruction is continuous and unique, and is connected with the communication history established between the two devices. This enables long-term continuous communication instruction testing.

[0046] Specifically, the current first transmit count value corresponding to the first transmit counter and the current first receive count value of the first receive counter are combined with a fixed test instruction CMD in a preset format to form a standardized test instruction. This standardized format allows the second device to quickly identify the instruction type and extract key count information after receiving the test instruction. Furthermore, the second device can use this to verify the communication quality of its downlink and determine whether its previous responses have been lost, thus achieving communication quality detection of both uplink and downlink channels based on simple instruction interaction.

[0047] Specifically, the format of the test command is "Test Command CMD + Send Counter + Receive Counter".

[0048] Specifically, after the test command is constructed, the first device sends the constructed test command to the communication bus through its physical communication interface, so as to transmit the test command to the second device through the communication bus.

[0049] Preferably, the instruction counter is used to control the number of times the master retransmits when it does not receive a response from the slave; the preset maximum instruction count value can be designed with a reasonable value according to product requirements to limit the upper limit of retransmission of test instructions.

[0050] Specifically, when controlling the first device to send a test command to the second device, it is also determined whether the first device sends a test command to the second device for the first time within a single test command sending cycle. If so, a preset maximum command count value is obtained, and the command count value corresponding to the command counter in the first device is updated to the preset maximum command count value. This step is to set an upper limit for retransmission of test commands. For example, if the host does not receive a response after a timeout, the command counter will decrement. If the command counter is not zero, retransmission will continue until the command counter is zero, at which point communication failure is determined and the failure counter is incremented.

[0051] Specifically, the instruction count is initialized to the preset maximum instruction count, which avoids the waste of test resources caused by unlimited retransmissions and reduces misjudgments caused by occasional network fluctuations by setting a reasonable number of retransmissions, thus ensuring that the test results are more in line with the actual communication scenario.

[0052] In one embodiment, after the first device and the second device complete the handshake operation, the method further includes: initializing a plurality of second counters in the second device; after the second device receives the test instruction sent by the first device, updating the second count values ​​corresponding to the plurality of second counters based on the test instruction; generating response data corresponding to the test instruction based on the updated second count values, and controlling the second device to send the response data to the first device.

[0053] In one embodiment, the plurality of second counters includes a second transmit counter and a second receive counter.

[0054] Specifically, the second transmission counter is used to cache the current first transmission count value corresponding to the first transmission counter in the first device carried in the received test command; the second receiver is used to count the number of times the second device correctly receives and parses the test command sent by the first device.

[0055] Specifically, the second transmit count value corresponding to the second transmit counter and the second receive count value corresponding to the second receive counter are respectively set to zero.

[0056] Specifically, after a successful handshake, multiple second counters in the second device are also initialized to ensure that the first and second devices start testing on the same baseline, thus guaranteeing the synchronization and accuracy of subsequent statistical data.

[0057] In one embodiment, updating the second count value corresponding to the plurality of second counters based on the test instruction specifically includes: obtaining the current first transmission count value carried in the test instruction; if the current first transmission count value is zero, then initializing the second reception count value corresponding to the second reception counter; if the current first transmission count value is not zero and the current first transmission count value is not equal to the second transmission count value corresponding to the second transmission counter, then updating the second reception count value corresponding to the second reception counter and updating the second transmission count value to the current first transmission count value.

[0058] Specifically, after receiving the test command, the second device can quickly extract the current first transmission count value corresponding to the first transmission counter in the first device carried by the test command, based on the format of the test command.

[0059] Specifically, when the current first transmission count value is obtained, it is determined whether the current first transmission count value is zero. If it is, it means that the test command is the initial test command sent by the first device in the current test session. Therefore, in response, the second device also initializes the second receive count value corresponding to its own second receive counter, that is, sets the second receive count value to zero. This ensures that while the first device's first transmission counter starts counting from 0, the second device's second receive counter also starts recording from 0, achieving strict synchronization between the two on the counting benchmark.

[0060] Specifically, if the current first transmit count is not zero, it indicates that the entire test session has proceeded normally; if the current first transmit count is not equal to the second transmit count, it indicates that the received test command is a new command sent by the first device. In this case, updating the second receive count in the second device and synchronizing the second transmit count is to accurately record the number of valid receptions and maintain the consistency of the counts between the two devices.

[0061] Specifically, updating the second receive counter corresponding to the second receive counter means incrementing the second receive counter value, that is, adding one to the second receive counter value to record this valid reception; at the same time, updating the second transmit counter value to the current first transmit counter value, so as to keep it synchronized with the transmit counter of the first device, and providing a benchmark for comparison when receiving test commands next time.

[0062] In one embodiment, generating response data corresponding to the test instruction based on the updated second count value specifically includes: obtaining the current second transmit count value corresponding to the second transmit counter and the current second receive count value corresponding to the second receive counter in the second device; constructing response data corresponding to the test instruction based on the current second transmit count value and the current second receive count value, and sending the response data to the first device.

[0063] Specifically, the data format of the response data is the same as that of the test command, both being: Test Command CMD + Send Counter + Receive Counter.

[0064] Step 102: Based on whether the first device receives the response data returned by the second device within a preset time, dynamically update the first count value corresponding to the plurality of first counters.

[0065] In one embodiment, after the first device sends a test command to the second device, a timeout is started; if the first device does not receive response data from the second device within the preset time, the instruction count value corresponding to the instruction counter is decremented to obtain an updated instruction count value; based on the updated instruction count value, an update operation is performed on the first count values ​​corresponding to the plurality of first counters, wherein the instruction count value corresponding to the instruction counter is updated to a preset maximum instruction count value when the first device first sends a test command to the second device within a single test command sending cycle.

[0066] Specifically, the timeout timer starts immediately after the first device sends the test command. This sets a clear time boundary for the communication response and is the core basis for judging whether the communication is timely.

[0067] Specifically, the preset time can be designed with a reasonable value according to product requirements, and is used to indicate the upper limit of reasonable delay in response when the two machines are communicating normally.

[0068] Specifically, the initial value of the command counter controls the number of retransmissions the master device will receive if it does not receive a response from the slave device, representing the maximum allowed number of retransmissions. When the first device does not receive a response from the second device within a preset time, the count value of the command counter is decremented. This is because the lack of response data may be an occasional situation caused by temporary interference rather than a permanent fault. The decrement operation records that one retransmission opportunity has been used. For example, if the command counter has a count value of 3, and it becomes 2 after the first timeout, it means that two more retransmissions can be attempted. This avoids the misjudgment of failure due to a single timeout, and prevents the waste of resources caused by unlimited retransmissions through limited number of attempts, thus balancing the fault tolerance and efficiency of the test.

[0069] In one embodiment, based on the updated instruction count value, an update operation is performed on the first count values ​​corresponding to the plurality of first counters. Specifically, this includes: comparing the updated instruction count value with a preset target value; if the updated instruction count value is not the preset target value, controlling the first device to resend the test instruction to the second device, and incrementing the first retransmission count value corresponding to the first retransmission counter; if the updated instruction count value is the preset target value, and the current first transmission count value of the first transmission counter is greater than the preset target value, then incrementing the first failure count value corresponding to the first failure counter, and controlling the first device to resend the test instruction to the second device.

[0070] Specifically, the preset target value is 0.

[0071] Specifically, if the updated instruction count value is not the preset target value, it means that there are still remaining retransmission opportunities. In this case, the test instruction is resent and the first retransmission count value corresponding to the first retransmission counter is incremented. This is to eliminate occasional communication interference through multiple attempts and to accurately record the retransmission behavior. This operation not only improves the fault tolerance of the test, but also provides key data for subsequent evaluation of communication stability by statistically analyzing the first retransmission count value, avoiding the distortion of results caused by directly judging failure due to a single timeout.

[0072] Specifically, if the updated instruction count value is the preset target value, it means that the number of retransmissions has been exhausted; and if the current first transmission count value of the first transmission counter is greater than the preset target value, it means that the first device and the second device have previously successfully exchanged test instructions.

[0073] Specifically, if the current first transmission count value of the first transmission counter is not greater than the preset target value, it indicates that the current test command transmission is the first data interaction after the handshake between the first and second devices. At this time, the communication link may not be fully stable. Even if the command count value is reduced to 0, it may be an initial link adaptation problem rather than a normal communication failure. If the current first transmission count value of the first transmission counter is greater than the preset target value, it indicates that at least one valid test command has been successfully sent before. At this time, the link has been adapted. If no response data is received from the second device after exhausting the number of retransmissions, it indicates that a normal communication failure has occurred, rather than an occasional problem in the startup phase. Therefore, in this case, the first failure count value corresponding to the first failure counter is incremented by 1. This can avoid miscounting special adaptation failures in the startup phase as normal communication failures and improve the reliability of the count value.

[0074] Specifically, the step of controlling the first device to resend the test command to the second device is as described in step 101 above, and will not be repeated here.

[0075] In one embodiment, if the first device receives response data returned by the second device within the preset time, the first count value corresponding to the plurality of first counters is dynamically updated based on the response data.

[0076] Specifically, when dynamically updating the first count value corresponding to the plurality of first counters based on the response data, the first receive count value is updated to the current second receive count value by obtaining the current second receive count value carried in the response data; and it is determined whether the updated first receive count value is greater than zero. If not, the first send count value corresponding to the first send counter is set to 1.

[0077] Step 103: Based on the updated first count value, evaluate the communication quality between the first device and the second device, and output the communication quality result.

[0078] In one embodiment, the current first retransmission count value and the current first failure count value corresponding to the first device are obtained. If the current first retransmission count value is greater than 0 and the current first failure count value is greater than 0, the communication quality result is output as data retransmission and communication failure exist. If the current first retransmission count value is greater than 0 and the current first failure count value is not greater than 0, the communication quality result is output as data retransmission exists. If the current first retransmission count value is not greater than 0 and the current first failure count value is greater than 0, the communication quality result is output as communication failure exists. If the current first retransmission count value is not greater than 0 and the current first failure count value is not greater than 0, the communication quality result is output as no data retransmission and no communication failure exist.

[0079] In one embodiment, the updated first count value is used as a log packet by the first device and the log packet is sent to the cloud. Based on the interaction between the cloud and the terminal system, the log packet is displayed on the terminal device to achieve a visual display of communication quality.

[0080] Example 2, see Figure 2 , Figure 2 This is a schematic diagram of an embodiment of a dual-machine communication quality testing device provided in this application. Corresponding to the above-described dual-machine communication quality testing method, this application also provides a dual-machine communication quality testing device. This dual-machine communication quality testing device includes modules for executing the above-described dual-machine communication quality testing method. This dual-machine communication quality testing device can be configured in terminals such as desktop computers, tablet computers, and laptops. Specifically, this dual-machine communication quality testing device is applied to a communication system including a first device and a second device, and includes: a test command sending module 201, a first value update module 202, and a communication quality evaluation module 203.

[0081] The test instruction sending module 201 is used to initialize multiple first counters in the first device and control the first device to send test instructions to the second device after the first device and the second device complete the handshake operation.

[0082] The first value update module 202 is used to dynamically update the first count value corresponding to the plurality of first counters based on whether the first device receives the response data returned by the second device within a preset time.

[0083] The communication quality assessment module 203 is used to assess the communication quality between the first device and the second device based on the updated first count value, and output the communication quality result.

[0084] In one embodiment, the plurality of first counters includes a first transmit counter, a first receive counter, a first retransmit counter, and a first failure counter.

[0085] In one embodiment, the test instruction sending module 201 is used to initialize a plurality of first counters in the first device, specifically including: setting the first sending count value corresponding to the first sending counter, the first receiving count value corresponding to the first receiving counter, the first retransmission count value corresponding to the first retransmission counter, and the first failure count value corresponding to the first failure counter to zero respectively.

[0086] In one embodiment, the test instruction sending module 201 is used to control the first device to send a test instruction to the second device.
