The application discloses a data version management method and device, equipment and a storage medium, which can be applied to an enterprise resource planning system. The method comprises the following steps: reading the registration information of a target transaction entity group in response to a transaction rollback instruction of target data, and calling a history model to perform data version management on the target data according to the registration information; if the registration information indicates that the registration has been completed, obtaining the transaction change data set of the target transaction entity group, and filtering the target transaction change version list corresponding to the target data from the transaction change data set to obtain the state before the change of the target data as the data basis for subsequent implementation of the rollback change operation, thereby supporting the transaction rollback operation; and performing the rollback change operation corresponding to the target data according to the state before the change, thereby guaranteeing the regrettable nature of the transaction operation, and simultaneously, the data version before the change does not need to be restored manually again, the management and control difficulty of the data version is simplified, and the management and control efficiency is improved.

The application discloses a kind of steep coal seam group horizontal segmentation and trend longwall mixed mining method, comprising: according to the stage height of thin coal seam single mining calculated and determined when coal seam slips or is destroyed opportunity;According to the segmentation height of thick coal seam, according to the space coordination requirement calculation, the space coordination requirement is, after thin coal seam is mined according to stage height single, the projection length of top contact caving length after thick coal seam is mined according to μ segmentation height stage is same in horizontal plane, caving zone and fracture zone and goaf overlap;According to the corresponding single mining progress, the thin coal seam and the thick coal seam are alternately mined.The stage height of thin coal seam single mining and the segmentation height of thick coal seam are quantitatively calculated according to coal seam slip or destruction opportunity, and thin coal seam and thick coal seam are alternately mined according to the requirement of space and time coordination, impact strata control, strata movement control and the coordination of mining efficiency improvement are realized.

This invention discloses an open-source automated testing system for electricity meters and data acquisition terminals, relating to the field of electricity meter testing technology. It aims to address the problem that the test coverage of existing electricity meter testing solutions is often determined by the experience of the testers. The system includes: a device management module for integrated control of the equipment and automatic control to meet testing conditions; a bottom-level platform module providing a set of step instructions for the smallest unit; a communication protocol module containing several protocols and parsing data according to the frame format structure and data type of the protocols; a script testing module that sets up script programs according to the test process and logic, calls the step instructions, and verifies the test results by reading, setting, and comparing data in the protocol library; and a task management module that establishes task numbers, selects script programs through task allocation, executes tests, and outputs test reports. This invention significantly improves test coverage and efficiency through automated testing technology, reducing reliance on developers.

The application discloses a kind of data-driven based groundwater extraction injection intelligent control method and system, it is related to data processing field;The multidimensional data of acquisition place and local water quality purification parameter are carried out data processing to obtain unified data set;Based on historical unified data set, target prediction model is constructed in combination with target area hydrogeology basic data;Unified data set is substituted into target prediction model to obtain the pollution concentration variation trend of groundwater and pollution range diffusion risk level;Based on pollution concentration variation trend, pollution range diffusion risk level, in combination with historical pollution control effect data, the preset pollution concentration early warning threshold, pollution range boundary early warning threshold are dynamically updated;Actual pollution concentration in current unified data set, pollution range and updated early warning threshold are compared to obtain target control instruction, to carry out groundwater extraction injection intelligent control, reduce manpower input and operation error, improve groundwater extraction injection efficiency.
