Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
As described in the background art, the communication command of the current Modbus RTU protocol is manually generated by technicians, and because different technicians have different levels of care and experience, the manner of manually generating the communication command has a high error rate. In addition, when the configuration file is slightly adjusted, technicians usually change part of the communication instructions on the basis of the communication instructions generated in the previous time, and at this time, the situation that part of the communication instructions are not correspondingly changed easily occurs, so that the error rate is further improved.
In order to solve the problem of the prior art, embodiments of the present invention provide a method and an apparatus for generating protocol information, and a terminal device. First, a protocol information generating method provided in an embodiment of the present invention is described below.
The executing body of the protocol information generating method may be a protocol information generating device, and the protocol information generating device may be a terminal device having a processor and a memory, for example, a control device in each industrial control system, such as a programmable controller, a server, a personal computer, or the like, and the embodiment of the present invention is not particularly limited.
As shown in fig. 1, a method for generating protocol information according to an embodiment of the present invention may include the following steps:
and step S110, reading a configuration file of the protocol.
The configuration file records a plurality of pieces of configuration information, and each piece of configuration information at least comprises a register initial address and byte number.
As shown in table one, a configuration file of a protocol is shown, where each row in the configuration file is a piece of configuration information, and each piece of configuration information includes information such as register address, byte number, name, default value, and the like.
Watch 1
It should be noted that, only part of information of each piece of configuration information is shown in table one, and the configuration information may further include a function code, a format, a unit, and the like, where the function code may be 02 read input state, the format may be a boul format, and the unit may be Status.
And step S120, sequentially dividing each piece of configuration information into corresponding configuration information groups according to a preset division rule according to the arrangement sequence of the initial addresses of the registers.
The preset division rule may be any division rule capable of achieving the following grouping purpose: each configuration information group comprises at least one piece of configuration information; for a configuration information group including at least two pieces of configuration information, the absolute value of the difference value between the register start address of the first configuration information and the register start address of the second configuration information is equal to the byte number of the first configuration information, the first configuration information and the second configuration information are adjacent configuration information in the arrangement order, and the register start address of the first configuration information is smaller than the register start address of the second configuration information.
After a lot of creative work, the applicant finds that the format of the communication command in the Modbus RTU protocol is relatively fixed, the variables in the communication command include an operation code, a register start address, and a register address length, and the format requirements of the communication command in the Modbus RTU protocol can be summarized as follows: the register address is discontinuous to configure information, and a communication instruction is generated independently; the configuration information of the register addresses can be combined to generate a communication instruction, and can also generate a communication instruction respectively. Referring to table one again, it can be found that the first piece of configuration information and the fourth piece of configuration information in table one are configuration information with discontinuous register addresses, and are not continuous with register addresses of other configuration information, and the second piece of configuration information, the third piece of configuration information, and the fifth to fourteenth pieces of configuration information in table one are configuration information with continuous register addresses.
Therefore, after the configuration file of the protocol is read, each piece of configuration information can be sequentially divided into corresponding configuration information groups according to the preset division rule according to the continuity condition of the register address of each piece of configuration information.
Optionally, the order of the register start addresses may be a sequence of the register start addresses from small to large, and accordingly, the specific processing in step S120 may be as follows: sequentially reading configuration information according to the sequence of the initial addresses of the registers from small to large; when the configuration information read at the current time is not the first piece of configuration information and the difference value between the register initial address of the configuration information read at the current time and the register initial address of the configuration information read at the previous time is equal to the byte number of the configuration information read at the previous time, dividing the configuration information read at the current time into a configuration information group to which the configuration information read at the previous time belongs or a new configuration information group; and under the condition that the configuration information read at the current time is not the first piece of configuration information and the difference value between the register initial address of the configuration information read at the current time and the register initial address of the configuration information read at the previous time is larger than the byte number of the configuration information read at the previous time, dividing the configuration information read at the current time into new configuration information groups.
In some embodiments, when the arrangement order of the register start addresses is from small to large, one implementation manner of the preset partition rule may be as follows:
for the case that the configuration information read at the current time is the first piece of configuration information, a configuration information group can be created, and then the configuration information read at the current time is directly divided into the configuration information group.
In the case that the configuration information read at the present time is not the first piece of configuration information, and the difference value between the register start address of the configuration information read at the present time and the register start address of the configuration information read at the previous time is equal to the byte number of the configuration information read at the previous time, it indicates that the configuration information read at the present time and the configuration information read at the previous time are configuration information with consecutive register addresses, so that the configuration information read at the present time can be divided into configuration information groups to which the configuration information read at the previous time belongs, or a new configuration information group can be created, and then the configuration information read at the present time is divided into the created new configuration information group.
For example, when the difference between the register start address of the second piece of configuration information and the register start address of the first piece of configuration information is equal to the number of bytes of the first piece of configuration information, the second piece of configuration information may be divided into a configuration information group to which the first piece of configuration information belongs, or a new configuration information group may be created, and then the second piece of configuration information is divided into the created new configuration information group.
The situation that the configuration information read at the current time is not the first piece of configuration information, and the difference value between the register starting address of the configuration information read at the current time and the register starting address of the configuration information read at the previous time is larger than the byte number of the configuration information read at the previous time indicates that the configuration information read at the current time and the configuration information read at the previous time are configuration information with discontinuous register addresses, so that a new configuration information group can be created, and then the configuration information read at the current time is divided into the created new configuration information group.
In addition, for the case that the configuration information read at the current time is not the first piece of configuration information, and the difference value between the register start address of the configuration information read at the current time and the register start address of the configuration information read at the previous time is smaller than the byte number of the configuration information read at the previous time, it indicates that an error exists in the configuration file, and at this time, the configuration information read at the current time can be removed, and alarm information is generated to prompt a technician to perform troubleshooting.
Optionally, the order of the register start addresses may also be a sequence of the register start addresses from large to small, and accordingly, the specific processing in step S120 may be as follows: sequentially reading configuration information according to the sequence of the starting addresses of the registers from large to small; when the configuration information read at the current time is not the first piece of configuration information and the absolute value of the difference value between the register starting address of the configuration information read at the current time and the register starting address of the configuration information read at the previous time is equal to the byte number of the configuration information read at the current time, dividing the configuration information read at the current time into a configuration information group to which the configuration information read at the previous time belongs or a new configuration information group; and under the condition that the configuration information read at the time is not the first piece of configuration information and the absolute value of the difference value between the register starting address of the configuration information read at the time and the register starting address of the configuration information read at the previous time is larger than the byte number of the configuration information read at the time, dividing the configuration information read at the current time into new configuration information groups.
In some embodiments, when the arrangement order of the register start addresses is from large to small, another implementation manner of the preset partition rule may be as follows:
for the case that the configuration information read at the current time is the first piece of configuration information, a configuration information group can be created, and then the configuration information read at the current time is directly divided into the configuration information group.
For the case that the configuration information read at the current time is not the first piece of configuration information, and the absolute value of the difference value between the register start address of the configuration information read at the current time and the register start address of the configuration information read at the previous time is equal to the byte number of the configuration information read at the current time, it indicates that the configuration information read at the current time and the configuration information read at the previous time are configuration information with continuous register addresses, so that the configuration information read at the current time can be divided into the configuration information groups to which the configuration information read at the previous time belongs, or a new configuration information group can be created, and then the configuration information read at the current time is divided into the created new configuration information groups.
For the case that the configuration information read at the current time is not the first piece of configuration information, and the absolute value of the difference value between the register start address of the configuration information read at the current time and the register start address of the configuration information read at the previous time is larger than the byte number of the configuration information read at the current time, it indicates that the configuration information read at the current time and the configuration information read at the previous time are configuration information with discontinuous register addresses, so that a new configuration information group can be created, and then the configuration information read at the current time is divided into the created new configuration information group.
Similar to the foregoing embodiment in which the start addresses of the registers are in the order from small to large, for the case that the configuration information read this time is not the first piece of configuration information, and the absolute value of the difference between the start address of the register of the configuration information read this time and the start address of the register of the configuration information read last time is smaller than the number of bytes of the configuration information read this time, it indicates that there is an error in the configuration file, and at this time, the configuration information read this time may be removed, and alarm information may be generated to prompt a technician to perform troubleshooting.
It should be noted that the implementation manner is not limited to the preset partition rule, and the preset partition rule may also be another partition rule. For example, a piece of configuration information may be randomly selected, and then all the configuration information is divided into two parts by using the configuration information as a boundary, and then the configuration information of the two parts is divided correspondingly.
Optionally, in consideration of the limitation of the register address length of the communication command, that is, the register address length threshold of the communication command, for example, the register address length of the communication command fixed in the Modbus RTU protocol, cannot exceed the maximum length of 255, or a manually set custom register address, such as 150, 180, etc., in this case, the specific process of dividing the configuration information read at the current time into the configuration information group to which the configuration information read at the previous time belongs or the new configuration information group may be as follows: if the sum value is less than or equal to the register address length threshold value of the communication instruction, dividing the configuration information read at the current time into configuration information groups to which the configuration information read at the previous time belongs, and otherwise, dividing the configuration information read at the current time into new configuration information groups; the sum value is the sum of the total byte number of the configuration information group to which the configuration information read last time belongs and the byte number of the configuration information read at the current time.
Optionally, the configuration information read at the current time may be further divided according to a relationship between the reading order and a preset dividing condition, and thus, the specific process of dividing the configuration information read at the current time into the configuration information group to which the configuration information read at the previous time belongs or the new configuration information group may be as follows: and if the reading sequence of the current time meets the preset dividing condition, dividing the configuration information read at the current time into the configuration information group to which the configuration information read at the previous time belongs, and otherwise, dividing the configuration information read at the current time into a new configuration information group.
In some embodiments, the preset division condition may be a function expression with respect to at least one argument, the dependent variable of the function expression being a reading order, e.g.Y＝2X、Y＝2X+1、Y＝2X2And X is a positive integer.
Taking the preset dividing condition as Y ═ 2X as an example, if the current reading order is the third time, it can be concluded that the current reading order does not satisfy the preset dividing condition, and at this time, the configuration information read at the current time can be divided into new configuration information groups.
And step S130, generating a communication instruction corresponding to the configuration information group.
The register initial address of the communication instruction is the minimum register initial address in the configuration information group, and the register address length of the communication instruction is the total byte number of the byte numbers of each configuration information included in the configuration information group.
It should be noted that other information, such as a function code, exists in the communication instruction, and it is considered that the generation process of the other information is conventional in the art, and is not described herein again.
Referring to table one again, the configuration file shown in table one may be divided into four configuration information groups, which are specifically as follows:
configuration information group 1: a first piece of configuration information;
configuration information group 2: a second piece of configuration information and a third piece of configuration information;
configuration information group 3: fourth configuration information;
configuration information group 4: the fifth piece of configuration information to the fourteenth piece of configuration information.
Accordingly, a communication command including the following key information may be generated:
communication instruction 1: register initial address 1, register address length 1;
and (3) communication command 2: register 10, register address length 2;
communication instruction 3: register 16, register address length 1;
and (4) communication instruction: register 144, register address length 10.
In the embodiment of the present invention, after the configuration file of the protocol is read, each piece of configuration information may be sequentially divided into the corresponding configuration information groups according to the arrangement order of the initial addresses of the registers and the preset division rule. Then, the configuration information group can be taken as a whole to generate a communication instruction corresponding to the configuration information group. Because the generated communication instruction corresponding to the configuration information group meets the format requirement of the communication instruction, the generated communication instruction cannot have an error condition as long as the configuration file has no error. Therefore, when the configuration file of the protocol is read, the corresponding communication instruction can be automatically generated, so that the manual generation of the communication instruction is replaced, the condition that the communication instruction is generated manually and is mistaken is avoided, and the labor cost is reduced.
