The invention relates to the technical field of surveying and mapping devices, and discloses a surveying and mapping device for road planning, which comprises a support rod and a surveying and mapping device arranged above the support rod, and also comprises a mounting part arranged on the support rod; the adjusting part is mounted on the supporting rod; the supporting part is arranged on the supporting rod; the mounting part comprises a limiting assembly, and the limiting assembly is mounted on the supporting rod; the pulling assembly is arranged on the supporting rod; the limiting assembly comprises a connecting rod slidably connected to the inner wall of the supporting rod, a connecting block is fixedly connected to the top of the connecting rod, and a containing groove is formed in the connecting block. By arranging the mounting part, the problems that in the using process of an existing surveying and mapping device, fasteners need to be screwed one by one during disassembly and assembly, the steps are tedious and time-consuming, during multi-point-position circulation surveying and mapping, time-consuming for repeated disassembly and assembly and erection is long, rapid entering and transition are inconvenient, and the overall operation progress is seriously slowed down are solved.

This invention provides a circular shuttle scheduling method, belonging to the field of warehouse system technology, including the following steps: After receiving instructions from the upper control system, the circular shuttle system automatically adapts to the task status, scheduling in an energy-saving mode when the task volume is small and in a fast mode when the task volume is large; after completing the task, the circular shuttle system feeds back information to the upper control system. This invention improves the operating efficiency of circular shuttles, meets the needs of tobacco industrial enterprises for multi-batch, high-volume transportation of raw materials, tobacco materials, finished cigarettes, etc., reduces material entry and exit time, and saves energy consumption of logistics equipment such as circular shuttles.

The utility model relates to the field of pipe bending device, especially a bending device for steel structure production, including unilateral clamping mechanism, reinforcing bar guide pulley group, connecting rod, elbow, installation platform, limiting plate, because the length of the placement chute is less than reinforcing bar, when reinforcing bar moves to the root of placement chute, cylindrical slide block sticks to reinforcing bar one side wall surface, guide pulley sticks to reinforcing bar another side wall surface reinforcing bar, clamps reinforcing bar, thereby reduces the placement time of many reinforcing bars, and when placing reinforcing bar, artificial both hands hold the both ends of reinforcing bar, because artificial both hands as support point and reinforcing bar both end distance is close, thereby the stability when placing reinforcing bar is high, and the both ends of reinforcing bar are respectively inserted into two placement chutes.

The present disclosure provides a permission query method and device, electronic equipment and storage medium, comprising: confirming and storing a relational database; wherein the relational database at least includes a subject and role comparison relationship, a subject and attribute comparison relationship, an attribute and role comparison relationship, and a role and object comparison relationship; in response to the authorization service starting, the relational database is converted into a graph data structure; in response to receiving a permission query request of a first subject, the corresponding object of the first subject is confirmed based on the graph data structure; wherein the attribute and role comparison relationship includes the comparison relationship between any role and all attributes owned by the role; the corresponding object of the first subject is the corresponding permission of the first subject; in this way, different comparison relationships are stored in the relational database, the same information is reflected by less data, and the storage time is reduced; when querying the permission, the graph data structure is used for querying, which can improve the query efficiency.

The invention discloses a device for preventing excessive water loss and hardening of lead paste in a paste mixing and storage hopper, which comprises a paste storage hopper arranged below a vacuum paste mixing machine, a fixed seat fixedly arranged on the side part of the paste storage hopper, an air cylinder fixedly arranged on the side part of the fixed seat, a push seat fixedly arranged at the telescopic end of the air cylinder, and a push rod fixedly arranged on the push seat, a laser distance measuring sensor is mounted in the pushing seat; the stirring mechanism is mounted at the bottom of the mounting cover and is used for stirring the lead paste; through linkage design of laser ranging and the PLC control system, regulation and control of the amount of the lead plaster in the plaster storage hopper are achieved, excessive accumulation of the lead plaster in the plaster storage hopper is avoided, the equipment load is greatly reduced, mechanical loss is reduced, the service life of equipment is prolonged, the amount of the lead plaster is controlled, the storage time and storage amount of the lead plaster are reduced, and the production efficiency is improved. The problem of water loss and hardening caused by long-time storage is effectively relieved, the consistency stability of the lead paste is ensured, the plate coating uniformity and the polar plate performance stability are improved, and the production efficiency and the product percent of pass are improved.

The application relates to the field of storage devices, in particular to a metadata storage method, a metadata recovery method, a metadata large block recovery method and a storage device, which comprises the following steps: dividing metadata into a plurality of metadata data streams, taking the metadata data stream as a storage unit, and storing the metadata in a metadata large block. The application can solve the problems of quick recovery of a quick start technology and introduction of additional write amplification.
