The invention provides a vehicle dealer data storage method, which comprises the following steps of: checking incoming vehicle dealer parameters, and if any parameter fails to be checked, terminating batch import; extracting a mapping relation among the large area, the small area, the province and the city from the database; querying whether there is special store data corresponding to a code in a database according to the special store code in the transmitted vehicle dealer parameters; if not, a logic deletion mark is generated, the creation information is filled, and the new dealer list is added; if so, updating the version number and the modification information; generating hierarchical codes on the basis of the inquired vehicle factory codes in combination with the special store codes, and creating / updating dealer organization objects in the region table; obtaining abnormal data of the previous steps and writing the abnormal data into a basic abnormal table; and writing the vehicle dealer data which are successfully put in storage into a cache. According to the method, three-stage closed-loop processing is realized, the problem of batch data integrity and format verification is solved, and data relevance is improved by organizing coding hierarchy.

The application discloses an automobile remote control key encryption method based on an AES algorithm, and relates to the technical field of intelligent automobiles, and comprises the following steps: obtaining manufacturer information, wherein the manufacturer information is a manufacturer authentication certificate and a manufacturer code set by a manufacturer; generating a serial number, wherein the serial number is divided into multiple plaintext blocks, and a first encrypted information is preliminarily encrypted by combining the multiple plaintext blocks with the manufacturer information; the first encrypted information is 108 bits; the first encrypted information is subjected to a bit complement encryption to generate second encrypted information, the serial number is combined with the manufacturer code to form the first encrypted information, the first encrypted information is complemented to 128 bits, the same manufacturer can encrypt different ciphertexts, and the third encrypted information is generated by combining a ciphertext stream and a key stream, so that the generation and combination of the third encrypted information can also not be according to fixed bits, the combination mode is more flexible, and statistical analysis attacks are effectively prevented.

This invention belongs to the field of PCIe device technology, specifically providing a method, apparatus, device, and medium for automatically adjusting transmitter balance values. The method includes the following steps: When the BIOS starts PCIe link training, it iterates and checks whether there are any PCIe devices connected to the PCIe root ports on the CPU side; when a PCIe device is detected, pre-write values ​​to the secondary bus register and auxiliary bus register of each PCIe root port; read the manufacturer code and device code of the PCIe device connected to the secondary bus; compare the read manufacturer code and device code with the manufacturer code and device code of the PCIe device whose transmitter balance value needs to be adjusted; when the comparison results match, call the write function to write the transmitter balance value and make the written transmitter balance value effective. This can save testing, production, and maintenance time.

The invention discloses a server detection method and a program product. Acquiring a hardware fingerprint vector and an operation parameter vector of the server, and determining an equipment state detection model corresponding to the server; wherein the hardware fingerprint vector comprises an equipment manufacturer code, a mainboard model code and a firmware version code; the operation parameter vector comprises a voltage ripple, a clock skew rate, a bus load rate and an environment temperature and humidity parameter; inputting the hardware fingerprint vector and the operation parameter vector into an equipment state detection model to obtain an equipment operation state of the server; wherein the equipment operation state comprises a normal state and at least one fault state; and determining a target response operation corresponding to the equipment running state of the server, and executing the target response operation. Therefore, the intelligent detection of the server can be realized, the potential hardware degradation risk in the server is avoided in time, and the accuracy of server detection is improved.

To enable store employees to perform routine checks to ensure that the circuit boards in gaming machines are not counterfeit, each board is marked with manufacturer-specific identification information. However, multiple identification information display units, each bearing different information, are detachably mounted on the printed circuit board via easily breakable wires. When the board is placed in its case, all but one identification information display unit are broken and discarded, leading to increased costs and larger board sizes. The goal is to prevent misidentification of the identification information display units, making daily checks easier, while also achieving appropriate space savings for the circuit board. [Solution] The identification information is arranged together with the manufacturer codes of multiple companies, and is composed of alphanumeric characters using the same font as the board management number, and the manufacturer codes of multiple companies are displayed separated by special characters.

The invention belongs to the technical field of Internet of Things equipment access management, and particularly relates to an MAC address storage method, an MAC address verification method and an MAC address verification device. The method comprises the steps that an MAC address is preprocessed, a 48-bit unsigned binary number is obtained, the high 24 bits of the MAC address are OUI manufacturer codes, and the low 24 bits of the MAC address are device identifiers; taking the high 24 bits of the 48-bit unsigned binary number as a bucket index, and searching a container in a bucket; and storing the MAC address in the searched barrel inner container according to an updating mode corresponding to the container type of the searched barrel inner container. According to the method, an OUI defined by IEEE and a Roaring Bitmap data structure are deeply integrated for the first time, MAC high 24-bit OUI is directly used as a bucket key, and the conflict risk of Hash bit reduction operation is avoided; and the containers are switched in real time based on the density of data in the buckets, and memory use is optimized.

To provide a gaming machine that can efficiently perform fraud prevention processing using manufacturer codes. [Solution] The gaming machine comprises a first control unit capable of managing a first manufacturer code, and a second control unit capable of receiving a first manufacturer code from the first control unit. The second control unit manages multiple second manufacturer codes belonging to the same group, and if there is no second manufacturer code among the multiple second manufacturer codes managed by the second control unit that corresponds to the first manufacturer code transmitted from the first control unit, the game is controlled to be disabled.

This improves the response time of the game token counting operation to the counting button, and reduces the burden on the player when pressing the counting button. [Solution] In the gaming machine of the present invention, there are multiple types of counting operations depending on the duration of the counting operation, the game value control means determines the type of counting operation according to the duration of the counting operation, the game value control means can output multiple pieces of information to the game control means, the multiple pieces of information include operation information regarding the presence or absence of a counting operation, there are first counting operations and second counting operations depending on the duration of the counting operation, the game control means has an initial information transmission means that transmits initial information to the game value control means at startup, the initial information transmission means transmits manufacturer information and product information as initial information, the manufacturer information includes a manufacturer code, and the product information includes a product code.
