Description

Technical Field

[0001] This invention relates to the field of power electronics technology, specifically to a device for inventorying and managing oilfield-specific storage equipment. Background Technology

[0002] Oilfield-specific storage equipment mainly includes the following categories, combining high-density storage, automated operation, and professional functional requirements. These include: automated racking and stacker cranes, employing automated racking systems to achieve rational high-level storage, and stacker cranes to complete automated storage and retrieval operations, significantly improving space utilization and operational efficiency; lifting equipment (lifts / elevators) for vertical material transport, combined with conveyor equipment to achieve bidirectional automated transportation, improving overall logistics efficiency; core processing and digitization equipment, specifically designed for oilfield core samples, including core collection, preparation, and digitization systems to ensure sample safety and research efficiency; computer management systems to monitor equipment operation status in real time, optimize inventory management, and exchange data with external systems (such as production and logistics) to improve management synergy; and safety and auxiliary equipment, including explosion-proof, fire-fighting, and ventilation facilities to ensure storage safety in the special environment of oilfields.

[0003] Existing technologies for inventory and management of warehousing equipment mostly employ manual inventory supplemented by high-tech methods such as barcode scanning and RFID to reduce human error. However, manual inventory is suitable for scenarios with a limited variety of goods and a small number of storage locations. By checking each storage location one by one to ensure that each item is recorded, its practicality is limited. Therefore, we propose a storage equipment inventory and management device specifically for oil fields. Summary of the Invention

[0006] Furthermore, it also includes a communication module, which is selected from one of the following: a WIFI module, Bluetooth, or a network cable.

[0007] Furthermore, the device can be connected to a computer host or a mobile application via the communication module.

[0008] Furthermore, the STM32 main control chip uses FreeRTOS to establish a multi-tasking mode and uses message queues and semaphores to achieve task synchronization.

[0009] Furthermore, the radio frequency module uses a reader / writer to read the information of the radio frequency tag and connect to the host computer to realize data acquisition and processing.

[0010] Furthermore, the encryption module uses either AES or RSA.

[0011] Furthermore, the battery management module uses a rechargeable lithium battery.

[0012] The beneficial effects of this invention are as follows: This invention uses IDs for equipment inventory and management. By using the serial number on the equipment, information such as the product production date, production unit, and quantity can be accurately obtained, greatly improving work efficiency. At the same time, it supports remote control operation, allowing the inventory of equipment in various locations to be carried out through a mobile APP or computer host, saving time and effort.

[0013] This invention is applicable to scenarios such as inventory of goods in oil fields, inventory of goods in warehouses, and inspection of equipment in work sites, providing users with fast, accurate, and convenient functions for inventory and management of goods.

[0014] This invention enables the counting and reading / writing of data from electronic tags. It boasts high read / write power, allowing for large-scale device reading operations.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] Please see Figure 1 - Figure 4 This invention provides an oilfield-specific storage equipment inventory and management device, comprising: an STM32 main control chip 10, an RF module 20, an encryption module 30, and a battery management module 40. The STM32 main control chip 10 is used to achieve efficient and stable data acquisition and processing, and coordinate the collaborative work of each module; the RF module 20 is used to transmit and receive wireless communication signals, ensuring stable interaction between the equipment and the tag; the encryption module 30 is used to encrypt / decrypt data, ensuring the security of data transmission or storage; and the battery management module 40 is used to provide a power source.

[0019] The RFID module 20 is used to count and read / write data from electronic tags. It has a high read / write power, which can meet the needs of large-scale device reading operations. It also supports multiple operation modes, including handheld operation via WIFI / Bluetooth / computer host, and can meet the needs of unattended remote operation.

[0020] In this embodiment, preferably, it also includes a communication module 50, which is selected from WIFI, Bluetooth or Ethernet; data transmission can be realized by setting the communication module 50.

[0021] In this embodiment, preferably, the device is connected to a computer host or a mobile application via the communication module 50.

[0022] In this embodiment, preferably, the STM32 main control chip 10 uses FreeRTOS to establish a multi-task mode and uses message queues and semaphores to achieve task synchronization; thus, multiple tasks can be performed simultaneously, improving work efficiency.

[0023] In this embodiment, preferably, the radio frequency module 20 is a reader / writer used to read the information of the radio frequency tag and connect to the host computer to realize data acquisition and processing.

[0024] In this embodiment, preferably, the encryption module 30 uses either AES or RSA to ensure data security.

[0025] In this embodiment, preferably, the battery management module 40 uses a rechargeable lithium battery, which can meet the needs of long-term use.

[0026] Working principle and usage process of this invention: After receiving the operation commands from the serial port / WIFI / Bluetooth, the STM32 main control chip 10 distinguishes the specific work content through protocol parsing and sends it to the specific task module. After processing the task, it returns the operation result and operation data to the serial port / WIFI / Bluetooth. The STM32 uses FreeRTOS to establish a multi-tasking mode and uses message queues, semaphores and other methods to realize task synchronization in order to meet the functional requirements. The Boot layer initializes the driver. The Boot layer checks whether the upgrade flag is set. If the upgrade flag is set, the program needs to be upgraded. The program upgrade logic operation is performed, all data is erased, and the data of each packet is checked. After the check is successful, the program is written. This continues until the program is completely written. Then the upgrade flag is reset and the device is restarted. If the program flag is set to not need an upgrade operation, the program is directly switched to the APP program to run. The APP initializes the driver, and initializes peripherals such as GPIO, UART, SPI, I2C, SDRAM, BLE, and WIFI; FreeRTOS task startup begins. In sequential task mode, tasks are started in order according to business requirements. After startup, all tasks are blocked and wait for task requests from the serial port. When a task request is received from the serial port, the task processing module distributes the task to the relevant functional modules for processing. After processing, a task success flag and data are returned, ending one task and waiting for the next task. Example 1
