The invention discloses a software upgrading method, computing equipment and mining equipment, and the software upgrading method comprises the following steps: determining a target upgrading object according to a preset strategy in response to writing authorization passing; when a target upgrade package corresponding to the target upgrade object is determined from the external mobile storage device, opening a write-in permission for writing in the target upgrade package for the mobile storage device in the read-only management and control state; and performing software upgrading control according to the written target upgrading package. According to the technical scheme, write authorization verification can be carried out on the external mobile storage device so as to realize access supervision on the mobile storage device, and read-only management and control can be carried out on the mobile storage device when the write authorization is passed; therefore, when the target upgrade object is subsequently determined and the target upgrade package corresponding to the target upgrade object is determined from the external mobile storage device, only the write-in permission for writing in the target upgrade package can be opened to ensure that all operations are carried out within an expected range, and the purpose of avoiding implantation of malicious codes is achieved.

The utility model discloses a kind of reinforcing steel bar structures of circle beam brick masonry wall top, it is related to building engineering technical field, including existing wall, existing circle beam, existing roof, reinforcing steel bar and fixed angle steel, existing circle beam is fixedly installed in the top of existing wall, the upper portion of existing circle beam is erected in the both ends of existing roof, reinforcing steel bar and fixed angle steel are respectively arranged in the both sides of existing wall, fixed angle steel is fixedly installed in the reentrant corner part of existing circle beam and existing roof connecting place, and fixed angle steel is fixedly connected with existing circle beam by through-bolt.The utility model uses the fixed angle steel fixed in the both sides of existing circle beam, as the fixed point of wall reinforcing steel bar top, can avoid a large number of reinforcing steel implantation circle beam and roof, reduce the damage caused to it, simultaneously make every longitudinal reinforcement have firm fixed point, enhance the overall stability of the newly added reinforcing structure of existing wall.And the utility model construction efficiency is high, fast, small, simple and quick.

The inserting rod is used for being inserted into the bottom of a rail, the stress rod extends out of the rear side of the base, the stress rod is treaded by an operator, and the anchor changing operation efficiency can be improved through the anchor changing machine fixing device.

The present application relates to the field of network information security technology, and specifically to a quantum-safe digital signature verification method and system. Specifically, the digital signature verification method introduces a one-time identity associated with the privacy identity of the user unit, thereby adding a new variable each time a signature is made, and then a one-time one-key signature is performed through a hash function based on a linear shift register, and further relies on an irreducible polynomial of a first quantum random number and a second quantum random number to jointly ensure the security of the signature, so that the security of the digital signature process reaches a quantum security level, and can resist increasingly powerful classical computing attacks and future disruptive quantum computing attacks. In the signature verification link, on the one hand, the integrity of the business information is verified based on the hash function of the linear shift register; on the other hand, the relevance and legitimacy are verified based on the one-time identity to ensure the non-repudiation of the user's digital signature.

The present invention relates to a fault intelligent diagnosis type power operation and maintenance system for a thermal power plant in the field of digital information transmission, comprising a plurality of power operation and maintenance systems, a twin system, a dispatching center and a communication module running in a thermal power plant, wherein the communication module comprises a signal relay device, and the plurality of power operation and maintenance systems all comprise a data acquisition module, a data processing module and an early warning response module. The twin system calls and executes preset response instructions according to the abnormal state of the power operation and maintenance system, and performs simulated operation in the twin system. When the abnormal state in the twin system disappears, the executed preset instructions are copied to the power operation and maintenance system and executed. When the detection data does not change as expected, the maintenance personnel are directly contacted to enter the site for maintenance, thereby greatly increasing the degree of automation of the power operation and maintenance system, eliminating the need for frequent participation of technical personnel, and easily achieving efficient fault diagnosis and troubleshooting.

This invention relates to an automatic software update method based on an in-vehicle embedded operating system, belonging to the field of computer software technology. It solves the problem that existing methods cannot simultaneously achieve reliable system startup and flexible, secure automatic software updates. The method includes: partitioning the physical disk into a system root partition, a user data partition, and an OverlayFS working partition; automatically entering safe mode by detecting kernel boot parameters, mounting the system root partition as read-only, and mounting specified directories as read-write overlays based on the OverlayFS file system and whitelist configuration files; dynamically switching the safe mode on and off via system services and command lines; upon detecting an external update device, entering maintenance mode, performing security verification on the update package from the external update device, and then performing an atomic update operation on the user data partition. This achieves both reliable operating system startup and flexible automatic software updates.
