The self-service and automatic transformation requirements of banks are met, the business efficiency is improved, and the safety of cash transaction is ensured.

The invention provides an underground compressed gas energy storage sealing system and a construction method, and the method comprises the following steps: 1, determining that a lining is a steel lining according to at least one of the material toughness, the material ductility, the fatigue damage resistance, the construction environment requirement and the construction period of the lining; secondly, the two sides of the steel lining are each coated with a solvent-free liquid epoxy coating, and the thickness of each solvent-free liquid epoxy coating is larger than or equal to 600 micrometers; thirdly, a plurality of bolts are arranged on the pre-embedded plate, and the pre-embedded plate meets the compression stress requirement; 4, the section of the lining is arranged to be of a corrugated circular structure in the length direction of the lining; and step 5, detecting the pressure bearing capacity of welding seams between the embedded plates and between the linings, and determining whether the sealing performance of the embedded plates and the linings is good or not. By means of the method, the sealing performance of the sealing system of the cavern can be guaranteed.

This invention discloses a method, apparatus, electronic device, and storage medium for storing and loading PLC programs, relating to the field of PLC technology. The method includes the following steps: opening and decrypting the PLC program's database file; the PLC program's database is an SQLite database, and the database file includes a system information table recording the original version information and modifiable version information of the PLC program's database; detecting the version of the modifiable version information and comparing it with the latest version compatible with the PLC programming software; if the version of the modifiable version information is not lower than the latest version compatible with the PLC programming software, then loading the PLC program. According to the PLC program storage and loading method of this invention, the loading speed of PLC programs can be significantly increased; moreover, when updating versions, the code for loading the PLC program does not need to include a version switch, making the code easier to maintain.

The present invention discloses a brain-computer shared control method and system for an air-ground collaborative unmanned system, including: step S1, constructing a mobile robot model; step S2, constructing an MPC shared controller based on the mobile robot model; step S3, constructing the action space, reward function and neural network model of the DDPG algorithm; step S4, training the neural network model based on DDPG to obtain an optimized model; step S5, adjusting the control authority parameters of the MPC-based shared controller according to the optimized model to control the robot to complete the specified task. The technical solution of the present invention can adjust the authority of the auxiliary controller and the driver under different working conditions and different states of the driver, thereby realizing the driver's control intention while ensuring the safety of the air-ground collaborative multi-robot system.

The invention discloses a multipurpose converter transformer valve hall firewall structure, which comprises a flat plate wall body, a deformation joint and a fire fighting equipment platform, and is characterized in that the flat plate wall body comprises a transverse wall body for replacing a valve hall outer wall and a longitudinal wall body for separating a plurality of converter transformers; the deformation joint is arranged at the junction of the transverse wall body and the longitudinal wall body and is arranged to be in a T shape. The deformation joint is filled with a refractory material; the fire-fighting equipment platform is arranged at the top end of the counter-fire side of the transverse wall body; the fire-fighting equipment platform is provided with a fire-fighting nozzle, and a pipeline is arranged in the fire-fighting equipment platform. Compared with the prior art, the T-shaped deformation joint is arranged on the back-to-fire surface of the joint of the longitudinal wall body and the transverse wall body of the firewall, and the deformation joint is filled with the refractory material, so that on one hand, the wall body has certain expansion and contraction capacity to weaken temperature stress; on the other hand, the wall surface is divided, and the problems that the wall surface cracks and the durability of the wall is affected due to the fact that the cast-in-place firewall is too long, and internal stress of the wall is generated when concrete is solidified, heated and cooled are solved.
