[0017] Figure 1is a flowchart of a dynamic identifier generation method based on multi-level distributed download provided by the present application.

[0018] Figure 2 is a structural diagram of a dynamic identifier generation device based on multi-level distributed download provided by the present application. DETAILED DESCRIPTION

[0019] The present application will be further described below with reference to the accompanying drawings. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application.

[0020] As shown in Figure 1 in one embodiment, a dynamic identifier generation method based on multi-level distributed download includes the following steps: step S110, hierarchical encoding of the master recipe ID and the step index to generate a global sub-identifier.

[0021] In some embodiments, the dynamic identifier generation method based on multi-level distributed download provided by the present application, step S110 specifically includes the following steps: step S111, taking the master recipe ID as the integer part and the step index under the master recipe ID as the decimal part, combining the integer part and the decimal part to obtain a combination result.

[0022] Step S112, hierarchical encoding of the master recipe ID and the step index based on the combination result of the integer part and the decimal part to generate a global sub-identifier.

[0023] It should be noted that each recipe has a unique master recipe ID, and the recipe under the master recipe ID has a plurality of different steps, and each step has a unique corresponding step index.

[0024] In a specific embodiment, the dynamic identifier generation method based on multi-level distributed download provided by the present application includes steps S1-S4: step S1, hierarchical encoding of the master recipe ID and the step index.

[0025] Specifically, by the formula RCP_DETAIL_ID = DINT_TO_REAL(RCP_ID) + INT_TO_REAL(RCP1_P_INDEX) * 0.01, the master recipe ID (integer part) and the step index (decimal part) are combined to generate a globally unique sub-identifier, and the recipe hierarchical encoding is realized (for example, the master recipe ID = 110, and the identifier of step 1 is 110.01), to ensure data traceability.

[0026] It should be noted that in the actual communication process, there is more than one recipe, so each recipe itself corresponds to a unique identifier, i.e. the main recipe ID (RCP ID). In addition, there are multiple different steps in the recipe, so each step also needs to correspond to a unique identifier, i.e. the step index (RCP1 P INDEX). In hierarchical encoding, both are combined, i.e. the globally unique sub-identifier (RCP DETAIL ID).

[0027] It should be further noted that in the above formula, there is only a first step index. If there is a second step index under the first step index (for example, second step 1.1 under first step 1), or a third step under the second step (for example, 1.1.1 under second step 1.1), then the globally unique sub-identifier As shown in the following formula: ; In the formula, represents the number of steps; is a constant, (or the reciprocal of ) must be greater than the number of elements after decomposition of each data set, which is usually 100.

[0028] In step S120, the SQL database is connected through ADO, and the recipe parameters corresponding to the main recipe ID are queried based on the global sub-identifier in hierarchical batches to write the recipe parameters into the PLC data block.

[0029] In some embodiments, the dynamic identifier generation method based on multi-level distributed download provided by the present application, step S120 specifically includes the following steps: step S121, calling the host computer to run the VBS script to connect the SQL database through ADO, and querying the step index under the main recipe ID as the recipe parameter according to the hierarchical batch in the global sub-identifier.

[0030] Step S122, write the recipe parameters into the PLC data block through the process Ethernet protocol, to call the PLC data block to verify the global sub-identifier, and obtain the verification result whether the global sub-identifier meets the preset requirement.

[0031] In some embodiments, the dynamic identifier generation method based on multi-level distributed download provided by the present application, step S120 specifically further includes the following steps: step S123, write the recipe parameters queried by the global sub-identifier which meets the preset requirement of the verification result into the register array according to the level of the step index, to control the device action through the register array according to the step index.

[0032] Step S124, store the recipe list and the corresponding recipe parameter list under all main recipe IDs through the SQL database, and associate multiple recipe lists through the dynamic identifier, to perform field retrieval on the recipe list according to the recipe parameters.

[0033] In specific embodiments, the application provides a multi-level distributed download-based dynamic identifier generation method, step S2, multi-module collaborative data transmission.

[0034] Specifically, the host computer (VBS script): connect to the SQL database through ADO, and query the recipe parameters in batches according to the dynamic identifier (for example: SELECT * FROM rcp_detail WHERE rcp_name='u6' AND PINDEX='s2'). Then, write the parameters into the PLC data block through the process Ethernet protocol (for example: DOWNLOAD data block_RCP1P_BLENDTIME). PLC (S7-1500 code): after receiving the dynamic identifier, check the formula legality (for example: check whether RCP1_P_INDEX is continuously increased); write the parameters into the register array according to the step index (for example: RCPX_RM_PERCENT[RCP1_P_INDEX]), and then implement the control of device action through the register array according to the step execution. Database (SQL Server): store the main recipe table (rcp_detail) and the sub-parameter table (rcp_fremode), and associate the multi-table data through the dynamic identifier, so as to support the quick retrieval according to the step index (for example: the PINDEX field in the rcp_detail table).

[0035] It should be noted that for the sender of the recipe, the specific recipe parameters of the recipe u6 and step s2 can be obtained based on the query recipe parameter statement, for example: SELECT * FROM rcp_detail WHERE rcp_name='u6' AND PINDEX='s2'.

[0036] Step S130, trigger the state bit through the host computer, and receive the index parameters from the PLC data block according to the current step parameters.

[0037] In some embodiments, the application provides a multi-level distributed download-based dynamic identifier generation method, step S130 specifically includes the following steps: step S131, trigger the state bit of the first value through the host computer, so as to send the current step parameters to the PLC data block, and call the PLC data block to set the state bit after receiving.

[0038] Step S132, when the host computer detects that the state bit changes, send the subsequent step parameters corresponding to the current step parameters to the PLC data block, and terminate the data transmission between the host computer and the PLC data block when the current step index is the set field.

[0039] In specific embodiments, the application provides a multi-level distributed download-based dynamic identifier generation method, and step S3 is a step-by-step handshake protocol.

[0040] Specifically, the interactive transmission between the PLC and the host computer is realized through the state bits (RCP_DOWN_ST, RCP_DOWN_ST_DELAY). First, the host computer triggers RCP_DOWN_START=1 to send the current step parameter. After the PLC receives it, RCP_DOWN_ST=0 is set. After the host computer detects the state change, the next index parameter is sent. When RCP_P_INDEX=RCP_STEPNO, the data transmission between the host computer and the PLC is terminated. At this time, the completion flag ST_RCP_DOWNOK=1 is set.

[0041] Step S140, based on the index parameter, dynamically updating the global sub-identifier to generate a dynamic identifier, the dynamic identifier being used to represent whether the step index under the main formula ID is issued completely.

[0042] In some embodiments, the application provides a multi-level distributed download-based dynamic identifier generation method, which further comprises the following steps: step S210, taking the main formula ID as the parent node and the step index under the main formula ID as the child node, constructing a binary tree, and the different step indexes at the same level in the binary tree are different child nodes on different sides.

[0043] Step S220, when the step index has a secondary sub-step, taking the sub-step index corresponding to the secondary sub-step as the child node of the secondary sub-step, updating the binary tree.

[0044] Step S230, the binary tree is verified by verifying the sequence, and when the verification sequence of the receiving end and the verification end is consistent, it is determined that all step indexes and sub-step indexes under the main formula ID are issued completely.

[0045] In specific embodiments, the application provides a multi-level distributed download-based dynamic identifier generation method, and step S4 is the construction and modification of the binary tree.

[0046] Specifically, a binary tree is constructed by taking the main recipe ID as the parent node and the step index under the main recipe ID as the child node. In the constructed binary tree, the peer subsequent step of each step is taken as a side child node (for example, a left child node), and the subordinate (first) step of each step is taken as the other side child node (for example, a right child node). Taking step 1.2 (corresponding to node D12) as an example, its peer subsequent step is 1.3, and therefore, node D13 is taken as the left child node of D12; and the subordinate (first) step of step 1.2 is step 1.2.1, and therefore, node D121 is taken as the right child node of D12. Then, the constructed binary tree is represented by a unique verification sequence, for example, the verification sequence can be a string of unique corresponding characters such as "001011000101101011", and the length of the verification sequence needs to be exactly twice the number of nodes in the binary tree. If the number of nodes in the binary tree does not exceed 5000, the above verification sequence usually occupies no more than 10 KB of data. The verification sequence is used for collation between the receiving party and the verifying party, and only when the collation result is consistent, it is indicated that the data communicated between the receiving party and the transmitting party has no missing and incorrect transmission. If there is missing, it is indicated that there is a missing value in the verification sequence, and if there is incorrect transmission, there is an inconsistent value in the verification sequence.
