[0027] This invention provides a data update method, apparatus, device, and storage medium for obtaining the latest modified data parameters of a target unit and ensuring that the data parameters can be updated normally.
[0028] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0029] It is understood that the executing entity of this invention can be a data update device, a terminal, or a server; no specific limitation is made here. This embodiment of the invention will be described using a server as an example.
[0030] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the data update method in this invention includes:
[0031] 101. Obtain the first time-sharing temperature control parameter of the target unit in at least one unit, and the target unit is connected to the control screen for communication.
[0032] Query the first time-sharing temperature control parameter of the target unit in at least one unit, and extract the first time-sharing temperature control parameter.
[0033] 102. Determine whether the control screen is in the state of issuing the second time-sharing temperature control parameters;
[0034] Determine whether a data transmission flag exists on the control screen. The data transmission flag indicates that the control screen is transmitting data. If a data transmission flag exists, it is determined that the control screen is in the state of transmitting the second time-sharing temperature control parameters. If a data transmission flag does not exist, it is determined that the control screen is not in the state of transmitting the second time-sharing temperature control parameters.
[0035] 103. If not, check whether the first time-sharing temperature control parameter is consistent with the saved target historical time-sharing temperature control parameter. The data types of the target historical time-sharing temperature control parameter and the first time-sharing temperature control parameter are the same.
[0036] When the control screen is not in the state of issuing the second time-sharing temperature control parameter, a cyclic redundancy check is performed on the first time-sharing temperature control parameter to obtain the first cyclic redundancy check code. It is then determined whether the first time-sharing temperature control parameter is consistent with the target historical time-sharing temperature control parameter. If the first cyclic redundancy check code is inconsistent with the target historical cyclic redundancy check code, then the first time-sharing temperature control parameter is inconsistent with the target historical time-sharing temperature control parameter; if the first cyclic redundancy check code is consistent with the target historical cyclic redundancy check code, then the first time-sharing temperature control parameter is consistent with the target historical time-sharing temperature control parameter.
[0037] 104. If the first time-sharing temperature control parameter is inconsistent with the target historical time-sharing temperature control parameter, the first time-sharing temperature control parameter is saved to the cache.
[0038] When the first time-sharing temperature control parameter is inconsistent with the target historical time-sharing temperature control parameter, the first time-sharing temperature control parameter is saved to the cache, for example, in flash memory.
[0039] 105. Update the first time-sharing temperature control parameters to at least one unit.
[0040] Once the first time-sharing temperature control parameter is detected as being saved to the cache, the system retrieves information on at least one unit that needs updating and sends the first time-sharing temperature control parameter to that unit. If it is determined that the first time-sharing temperature control parameter is inconsistent with the target historical parameter, the system can either save the first time-sharing temperature control parameter to the cache first, and then update it to at least one unit; or it can update the first time-sharing temperature control parameter to at least one unit first, and then save it to the cache.
[0041] In this embodiment of the invention, the first time-sharing temperature control parameter of the target unit is obtained, it is determined that the control screen is not in the state of issuing the second time-sharing temperature control parameter, and the first time-sharing temperature control parameter that is inconsistent with the historical time-sharing temperature control parameter is updated to at least one unit, so as to obtain the latest modified data parameters of the target unit and ensure that the data parameters can be updated normally.
[0042] Please see Figure 2 Another embodiment of the data update method in this invention includes:
[0043] 201. Send a test command to the target unit. The test command is used to check whether the target unit is communicating normally.
[0044] A detection command is sent to the target unit to check whether the target unit is communicating normally. If the target unit receives a reply within a preset time, the target unit is determined to be communicating normally; if the target unit does not receive a reply within the preset time, the target unit is determined to be communicating abnormally.
[0045] 202. If the target unit is found to have communication abnormalities according to the detection command, then determine whether there are temporary time-sharing temperature control parameters in the buffer;
[0046] If the target unit is found to have communication abnormalities, check if a checksum header exists in the cache; if it exists, determine if temporary time-sharing temperature control parameters exist in the cache; if it does not exist, determine if temporary time-sharing temperature control parameters do not exist in the cache.
[0047] For example: when the target unit is found to have communication abnormalities, if a check header is read, such as 0x3E1F, it is determined that there are temporary time-sharing temperature control parameters in the cache; if the check header is not read, it is determined that there are no temporary time-sharing temperature control parameters in the cache.
[0048] 203. If not, determine whether to update the data parameters for at least one unit based on the preset time-sharing temperature control parameters;
[0049] If no temporary time-sharing temperature control parameters exist, the preset time-sharing temperature control parameters are written to a preset storage address and a verification header is generated. The preset time-sharing temperature control parameters and the verification header are stored in the cache. Cyclic redundancy check (CR) is performed on the preset time-sharing temperature control parameters to obtain a preset CR code. The preset CR code is compared with the second historical CR code to determine whether the preset time-sharing temperature control parameters and the second historical CR code are consistent. The second historical CR code is the verification code of the second historical CR parameter. When no temporary time-sharing temperature control parameters exist, the second historical CR code is an initial value, for example, 0. If the preset CR code and the second historical CR code are inconsistent, the preset time-sharing temperature control parameters are inconsistent with the second historical time-sharing temperature control parameters. If the preset CR code and the second historical CR code are consistent, the preset time-sharing temperature control parameters are consistent with the second historical time-sharing temperature control parameters.
[0050] When the preset time-sharing temperature control parameters are inconsistent with the second historical time-sharing temperature control parameters, the verification head and the preset time-sharing temperature control parameters are stored in the cache, and the preset time-sharing temperature control parameters are updated to the at least one unit.
[0051] 204. If present, determine whether to update the data parameters for at least one unit based on the temporary time-sharing temperature control parameters;
[0052] If it exists, the temporary time-sharing temperature control parameters are stored in the preset storage address; the temporary time-sharing temperature control parameters are subjected to cyclic redundancy check to obtain the temporary cyclic redundancy check code; based on the temporary cyclic redundancy check code and the saved first historical cyclic redundancy check code, it is determined whether to update the temporary time-sharing temperature control parameters to at least one unit, where the first historical cyclic redundancy check code is the check code of the first historical time-sharing temperature control parameters.
[0053] If temporary time-sharing temperature control parameters exist, they are stored in a preset storage address. A cyclic redundancy check (CR) is performed on these parameters to obtain a temporary CR code. This temporary CR code is then compared with a first historical CR code to determine if the temporary time-sharing temperature control parameters are consistent with the first historical CR code. If they are inconsistent, the temporary time-sharing temperature control parameters are not consistent with the first historical CR code; otherwise, they are consistent.
[0054] When the temporary time-sharing temperature control parameters are inconsistent with the first historical time-sharing temperature control parameters, the verification header and the temporary time-sharing temperature control parameters are stored in the cache, and the temporary time-sharing temperature control parameters are updated to the at least one unit.
[0055] 205. If the target unit is found to be in normal communication according to the detection command, the first time-sharing temperature control parameter of the target unit in at least one unit is obtained, and the target unit is connected to the control screen.
[0056] When the target unit is confirmed to be in normal communication according to the detection command, the first time-sharing temperature control parameter of the target unit in at least one unit is queried and extracted.
[0057] 206. Determine whether the control screen is in the state of issuing the second time-sharing temperature control parameters;
[0058] Determine whether a data transmission flag exists on the control screen. The data transmission flag indicates that the control screen is transmitting data. If a data transmission flag exists, it is determined that the control screen is in the state of transmitting the second time-sharing temperature control parameters. If a data transmission flag does not exist, it is determined that the control screen is not in the state of transmitting the second time-sharing temperature control parameters.
[0059] 207. If not, check whether the first time-sharing temperature control parameter is consistent with the saved target historical time-sharing temperature control parameter. The target historical time-sharing temperature control parameter and the first time-sharing temperature control parameter have the same data type.
[0060] If the control screen is not in the state of issuing the second time-sharing temperature control parameter, then the first time-sharing temperature control parameter is subjected to cyclic redundancy check to obtain the first cyclic redundancy check code; the first cyclic redundancy check code is compared with the saved target historical cyclic redundancy check code, which is the check code of the target historical time-sharing temperature control parameter; if the first cyclic redundancy check code is inconsistent with the target historical cyclic redundancy check code, then it is determined that the first time-sharing temperature control parameter is inconsistent with the target historical time-sharing temperature control parameter.
[0061] When the control screen is not in the state of issuing the second time-sharing temperature control parameter, a cyclic redundancy check is performed on the first time-sharing temperature control parameter to obtain the first cyclic redundancy check code. It is then determined whether the first time-sharing temperature control parameter is consistent with the target historical time-sharing temperature control parameter. If the first cyclic redundancy check code is inconsistent with the target historical cyclic redundancy check code, then the first time-sharing temperature control parameter is inconsistent with the target historical time-sharing temperature control parameter; if the first cyclic redundancy check code is consistent with the target historical cyclic redundancy check code, then the first time-sharing temperature control parameter is consistent with the target historical time-sharing temperature control parameter.
[0062] 208. If the first time-sharing temperature control parameter is inconsistent with the target historical time-sharing temperature control parameter, the first time-sharing temperature control parameter is saved to the cache.
[0063] When the first time-sharing temperature control parameter is inconsistent with the target historical time-sharing temperature control parameter, the first time-sharing temperature control parameter is saved to the cache, for example, in flash memory.
[0064] 209. Update the first time-sharing temperature control parameters to at least one unit.
[0065] Once the first time-sharing temperature control parameter is detected as being saved to the cache, the system retrieves information on at least one unit that needs updating and sends the first time-sharing temperature control parameter to that unit. If it is determined that the first time-sharing temperature control parameter is inconsistent with the target historical parameter, the system can either save the first time-sharing temperature control parameter to the cache first, and then update it to at least one unit; or it can update the first time-sharing temperature control parameter to at least one unit first, and then save it to the cache.
[0066] In this embodiment of the invention, by determining whether the target unit is communicating normally, a method for updating time-division temperature control parameters in abnormal and normal states of the target unit is established. This method enables the acquisition of the latest modified data parameters of the target unit in both abnormal and normal states, ensuring that the data parameters can be updated normally.
