Description

Technical Field

[0001] The present invention relates to the technical field of communication protocols, and in particular to a communication debugging method, system, device and medium based on dynamic optimization of multiple parameters, and in particular to an application in the ModBus communication protocol. Background Art

[0002] With the rapid development of industrial automation and the Internet of Things (IoT), the ModBus protocol, a widely used industrial communication protocol, has become increasingly important in terms of its debugging methods and systems. Within the realm of industrial communication technology, ModBus, as one of the core communication protocols for interconnecting IIoT devices, is widely used in communication debugging scenarios for network devices such as PLCs, inverters, and IoT sensors. Traditional ModBus debugging methods rely on manual configuration of communication parameters (such as slave address, baud rate, and parity bit) and operation through PC-based software (such as ModBus Poll and Modscan). This makes it difficult to meet the IIoT's "plug-and-play" and "mobile debugging" requirements.

[0003] In traditional ModBus communications, slave addresses must be manually configured (ranging from 1 to 247). When multiple devices are on the bus, duplicate addresses can easily lead to bus conflicts, causing communication failures. Existing methods lack automated address scanning and conflict arbitration mechanisms, requiring individual device configuration during commissioning. Single-device address configuration takes over 120 seconds, and repeated conflict troubleshooting is required, severely impacting networking efficiency.

[0004] To address the shortcomings of existing technologies, the present invention proposes a ModBus debugging method and system based on multi-protocol feature recognition and dynamic self-optimization of multiple parameters. This method utilizes multi-protocol feature recognition technology to automatically identify multiple protocol features, significantly expanding the debugging scope. Furthermore, through dynamic self-optimization of multiple parameters, parameters can be dynamically adjusted based on the real-time communication environment, further improving debugging accuracy and efficiency.

[0082] Reference Figure 1 FIG. 1 is a flow chart of a method for dynamically optimizing communication based on multiple parameters according to an embodiment of the present invention. In this embodiment, the method for dynamically optimizing communication based on multiple parameters includes:

[0083] S1. Use the host device to send a test instruction to the corresponding slave device according to a preset instruction format and a preset slave address.

[0084] In an embodiment of the present invention, the format of the instruction sent may be slave address+function code+data field+CRC16 checksum.

[0085] In the embodiment of the present invention, the host device may be a PC host, which is used to send instructions to the slave device and perform communication debugging.

[0086] In the embodiment of the present invention, the slave station address is a communication address based on the ModBus communication protocol.

[0087] In detail, the slave address belongs to one of a preset address set, and each address in the address set is set with a serial number.

[0088] Furthermore, under the ModBus communication protocol, the address set includes a maximum of 247 slave station addresses, with an address range of 1-247.

[0089] In the embodiment of the present invention, the ModBus communication protocol is an industrial communication protocol widely used in the fields of industrial automation and the Internet of Things. It is mainly used to transmit data between various devices, such as programmable logic controllers (PLCs), sensors, and meters.

[0090] In an embodiment of the present invention, the method of using the host device to send a test instruction to the corresponding slave device according to a preset instruction format and a preset slave address includes:

[0091] Obtaining response data of the host device to a preset data read instruction;

[0092] Performing protocol feature identification on the slave device according to the reply data to obtain a protocol identification result;

[0093] Determine whether the slave device satisfies the MODBUS TCP or MODBUS RTU protocol characteristics at the same time according to the protocol identification result;

[0094] If the slave device does not meet the MODBUS TCP or MODBUS RTU protocol characteristics, the test instruction is sent to a new slave device using the host device and the slave address of the next queue;

[0095] If the slave device satisfies the MODBUS TCP or MODBUS RTU protocol features at the same time, the test instruction is subjected to protocol conversion based on a preset protocol priority to obtain a converted test instruction;

[0096] Sending the converted test instruction to the new slave device using the host device and the slave address of the next queue;

[0097] The protocol features of MODBUS_TCP and MODBUS_RTU are utilized to complete protocol identification of communication data and conversion between the two protocols.

[0098] In detail, the ModBus TCP and the ModBus RTU are two different versions of the ModBus communication protocol. ModBus TCP uses Ethernet transmission and is based on the TCP / IP protocol. It is suitable for high-speed communication and is widely used in industrial automation and the Internet of Things. ModBus RTU uses serial communication (such as RS-232 or RS-485), and data is transmitted in binary format. It is suitable for low-speed communication and is commonly used in industrial field buses.

[0099] In detail, the protocol feature identification is carried out to the slave device according to the reply data, by checking whether the first 7 bytes of the reply data meet the MBAP header specification of ModBus TCP, the MBAP header specification is: transaction marker 2 bytes, protocol marker 2 bytes (fixed to 0x0000), length 2 bytes, identifier 1 byte, the entire data packet has no CRC check, meets the MBAP logo, then the protocol of the device belongs to the ModBus_TCP protocol; and checking the last 2 bytes of the reply data as CRC value, calculating the CRC16 check code of the first N-2 bytes for comparison, if consistent, it means that the protocol of the device belongs to the ModBus_RTU protocol.

[0100] In detail, the preset protocol priority may be ModBus TCP priority or ModBus RTU priority, and may be set in advance according to the usage scenario.

[0101] S2. Calculate the response time according to the baud rate of the host device, and obtain response data of the slave device corresponding to the slave address to the test instruction within the response time.

[0102] In the embodiment of the present invention, the baud rate refers to the rate used for communication, the unit is bps, and the initial default is 9600bps.

[0103] In the embodiment of the present invention, the calculation formula of the response time is as follows:

[0104]

[0105] Wherein, t is the response time, L is the preset data frame length, B is the baud rate, and m is the preset response delay.

[0106] Specifically, the data frame refers to the standard frame length of the ModBus RTU broadcast instruction (the address scan instruction is 8 bytes, including a function code, an address field, etc.).

[0107] In detail, the preset response delay may be 50 ms.

[0108] S3. Determine, based on the response data, whether the slave device completes the response within the response time.

[0109] In an embodiment of the present invention, judging whether the slave device has completed the response within the response time based on the response data is performed by judging whether the response data is empty. If the response data is not empty, it is judged that the slave address has completed the response within the response time; if the response data is empty, it is judged that the slave address has not completed the response within the response time.

[0110] If the slave device does not complete the response within the response time, S4 is executed to determine that the slave address of the slave device is an invalid address.

[0111] In the embodiment of the present invention, when it is determined that the slave address of the slave device is an invalid address, S8 is executed to sort the slave addresses in ascending order.

[0112] If the slave device completes the response within the response time, step S5 is executed to determine whether there is an address conflict based on the response data.

[0113] In an embodiment of the present invention, determining whether an address conflict exists based on the response data refers to performing a CRC check on the response data to determine whether data redundancy exists. If data redundancy exists in the response data, it is determined that an address conflict exists; if data redundancy does not exist in the response data, it is determined that no data conflict exists.

[0114] If there is an address conflict, S6 is executed to determine that the slave address of the slave device is a conflicting address, and address reallocation processing is performed on the conflicting address.

[0115] In an embodiment of the present invention, the address reallocation processing of the conflicting addresses means that the slave station address with the smallest ID is retained first, and then the other slave station addresses are allocated to the next free address in sequence (such as address 1 conflicts → ID2 is allocated to address 2, and ID3 is allocated to address 3).

[0116] In the embodiment of the present invention, the address reallocation processing of the conflicting address includes:

[0117] Obtain an ID list of all slave addresses in the conflicting address;

[0118] Arrange all slave station addresses in the conflicting addresses in ascending order of ID according to the ID list to obtain an ascending address list;

[0119] Obtain the address with the smallest ID in the ascending address list according to the ID list to obtain the smallest ID address;

[0120] Confirm that the minimum ID address is a valid address;

[0121] The remaining addresses in the ascending address list are sequentially allocated to free addresses.

[0122] In the embodiment of the present invention, when it is determined that the slave address of the slave device is a conflicting address, address reallocation processing is performed on the conflicting address, thereby ensuring that each slave address has only one response data.

[0123] In the embodiment of the present invention, when it is determined that the slave address of the slave device is a conflicting address, after address reallocation processing is performed on the conflicting address, S8 is executed to sort the slave addresses in ascending order.

[0124] If there is no address conflict, step S7 is executed to determine whether the slave address of the slave device is a valid address.

[0125] S8, after sorting the slave station addresses in ascending order, return to S1, using the host device to send a test instruction to the corresponding slave station device according to a preset instruction format and a preset slave station address.

[0126] In an embodiment of the present invention, after the slave station address is in ascending order, it means selecting the next adjacent address of the current slave station address as the new slave station address. For example, if the slave station address is "1", then after the slave station address is in ascending order, the new slave station address is "2".

[0127] S9. After sending the test instruction to all slave station addresses, all invalid addresses are acquired to obtain an invalid address set.

[0128] In the embodiment of the present invention, there are 247 slave station addresses in total. After the test instruction is sent to the 247th slave station address, it is confirmed that all slave station addresses have been sent.

[0129] The obtaining of all invalid addresses and obtaining of an invalid address set means that each time the test instruction is sent to a slave address, if the slave address of the slave device is determined to be an invalid address, a record is made, and all slave addresses determined to be invalid addresses are obtained to obtain the invalid address set.

[0130] S10. Dynamically optimize communication parameters based on the invalid address set and a preset communication parameter group characteristic segment to obtain an optimal communication parameter group, and perform communication between the master and slave devices based on the optimal communication parameter group.

[0131] In an embodiment of the present invention, the dynamic optimization of communication parameters based on the invalid address set and the preset communication parameter group characteristic segment to obtain the optimal communication parameter group includes:

[0132] Obtaining a preset communication parameter group characteristic segment, and performing permutations and combinations on the communication parameters in the communication parameter group characteristic segment to obtain a communication parameter group set;

[0133] Arranging the communication parameter group set based on priority to obtain a communication parameter group sequence;

[0134] Selecting the first communication parameter group in the communication parameter group sequence as the test parameter group;

[0135] Sending a debugging instruction to an address in the invalid address set based on the test parameter group;

[0136] Acquire response quality data of the addresses in the invalid address set to the debug instruction;

[0137] Calculating a communication quality evaluation parameter based on the response quality data;

[0138] Determining whether the communication quality assessment parameter is greater than or equal to a preset quality threshold;

[0139] If the quality assessment parameter is less than the quality threshold, selecting the next communication parameter group in the communication parameter group sequence as a new test parameter group, and returning to the step of sending a debugging instruction to the address in the invalid address set based on the test parameter group;

[0140] If the quality assessment parameter is greater than or equal to the quality threshold, confirming that the test parameter group is the optimal communication parameter group;

[0141] When the debugging instruction is sent to the addresses in the invalid address set according to all communication parameter groups in the communication parameter group sequence, and no communication quality assessment parameter greater than or equal to the quality threshold is obtained, all communication quality assessment parameters are acquired to obtain a communication quality assessment parameter set;

[0142] The communication parameter group corresponding to the communication quality evaluation parameter with the largest communication quality evaluation parameter set is selected as the optimal communication parameter group.

[0143] In the embodiment of the present invention, the characteristic segment of the communication parameter group includes baud rate, check mode, stop bit, and timeout threshold.

[0144] In an embodiment of the present invention, the communication parameter group set obtained by permuting and combining the communication parameters in the communication parameter group characteristic segment refers to permuting and combining different baud rates, parity check modes, stop bits, and timeout thresholds. For example, the baud rates include 1200, 2400, 4800, 9600, 38400, 57200, and 115200, totaling seven different frequencies; the data bits include 8, 7, 6, and 5; the parity check modes include none, odd, and even, totaling three; the stop bits include 1, 1.5, and 2, totaling three; and the timeout thresholds include 100, 200, 500, 1000, 2000, and 5000, totaling six. Therefore, the total number of parameter groups is 7*4*3*3*6=1512.

[0145] In the embodiment of the present invention, the communication parameter group set is arranged based on priority by defining commonly used parameters as high priority. For example, if the commonly used baud rate is 96000bps, the baud rate 9600bps is defined as "priority 1".

[0146] In an embodiment of the present invention, calculating a communication quality evaluation parameter based on the response quality data includes:

[0147] Obtaining the bit error rate, effective throughput, round-trip delay, and address conflict frequency included in the response quality data;

[0148] Determining that the bit error rate, the effective throughput, the round-trip delay, and the address conflict frequency are all within a valid range;

[0149] If the bit error rate, the effective throughput, the round-trip delay, and the address conflict frequency are not all within a valid range, outputting an error signal;

[0150] If the bit error rate, the effective throughput, the round-trip delay, and the address conflict frequency are all within a valid range, performing an exponential operation on the bit error sensitivity index as an exponent of the bit error rate to obtain a bit error term;

[0151] Multiplying the round-trip delay by a preset delay adjustment coefficient to obtain a multiplication factor, and calculating a ratio of the effective throughput to the multiplication factor to obtain a ratio term;

[0152] Multiplying the address conflict frequency by a preset conflict penalty factor, taking the negation of the product to obtain a negation factor, and performing an exponential operation using the negation factor as the exponent of the base of a natural logarithm to obtain a conflict term;

[0153] The communication quality evaluation parameter is obtained by subtracting the bit error term from a preset integer and multiplying the resultant value by the ratio term and the conflict term.

[0154] In detail, the preset integer may be 1.

[0155] In the embodiment of the present invention, the calculation formula of the communication quality evaluation parameter is as follows:

[0156]

[0157] Among them, CQAM is the communication quality evaluation parameter, BER is the bit error rate contained in the response quality data, α is the preset error sensitivity index, T is the effective throughput contained in the response quality data, β is the preset delay adjustment coefficient, RTT is the round-trip delay contained in the response quality data, γ is the preset conflict penalty factor, and C is the address conflict frequency contained in the response quality data.

[0158] In detail, the error sensitivity index is a coefficient used to amplify the penalty for high error, and the error sensitivity index may be 1.2.

[0159] In detail, the delay adjustment coefficient is used to normalize the delay impact (for example, when the delay adjustment coefficient is 100, the round-trip delay is 200ms, and the corresponding denominator is 20000ms), and the delay adjustment coefficient can be 100.

[0160] In detail, the conflict penalty factor is used to control the attenuation strength of the conflict rate, and the conflict penalty factor may be 0.5.

[0161] In this embodiment of the present invention, the quality threshold may be 1.

[0162] In an embodiment of the present invention, after obtaining a preset communication parameter group characteristic segment and permuting and combining the communication parameters in the communication parameter group characteristic segment to obtain a communication parameter group set, the method further includes:

[0163] Obtaining a communication quality evaluation coefficient corresponding to each communication parameter group in the communication parameter group sequence to obtain a coefficient set;

[0164] Calculating in real time a communication quality evaluation coefficient when performing communication based on the optimal communication parameter group to obtain a detection evaluation coefficient;

[0165] Determining in real time whether the detection evaluation coefficient is less than the quality threshold;

[0166] When the detection evaluation coefficient is less than the quality threshold, determining whether the detection evaluation coefficient is greater than or equal to a preset second quality threshold;

[0167] If the detection evaluation coefficient is greater than or equal to the second quality threshold, adjusting the communication parameter group according to a preset balancing mode;

[0168] If the detection evaluation coefficient is less than the second quality threshold, performing communication parameter self-repair to obtain a repair result;

[0169] When it is determined according to the repair result that the repair has failed, the host device is restarted.

[0170] In detail, the second quality threshold may be 0.6.

[0171] In detail, the adjusting of the communication parameter group according to the preset balancing mode refers to selecting a communication parameter group with a communication quality evaluation coefficient between 0.6 and 1 in the communication parameter group sequence for dynamic replacement.

[0172] In detail, the communication parameter self-repair refers to performing communication repair using a communication parameter group having a communication quality evaluation coefficient greater than 0.6 selected from the communication parameter group sequence.

[0173] In the embodiment of the present invention, by dynamically optimizing communication parameters based on the invalid address set and the preset communication parameter group characteristic segment, an optimal communication parameter group is obtained, thereby improving the efficiency of communication debugging.

[0174] In the embodiment of the present invention, by performing communication between the master and slave devices based on the optimal communication parameter group, the communication efficiency between the master and slave devices can be improved.

[0175] This solution, based on the ModBus communication protocol, aims to test the communication of slave devices and improve communication quality by adjusting communication parameters. The host device first sends a test command to the slave address in a preset format. The host device then determines whether to convert the command based on the protocol characteristics. The response time is then calculated based on the baud rate and the response data is retrieved. The response is then determined to determine whether the slave address completes the response within the time limit. If not, the address is considered invalid. If a response is completed, the address is further determined to determine if there is an address conflict, in which case the address is reallocated. The command process is repeated after the slave addresses are sorted in ascending order until all addresses have been sent, generating a set of invalid addresses. Dynamic debugging is then performed based on the invalid address set and the preset communication parameter group signatures. Parameter groups are generated through permutations and sorted, tested sequentially, and evaluation parameters are calculated based on the response quality data to select the optimal communication parameter set. Furthermore, communication quality is monitored in real time, and parameter adjustments, self-repair, or host device restarts are performed based on different thresholds. This approach enables fully automatic scanning and conflict avoidance of slave addresses, improving communication stability.
