Abstract
Description
Technical Field
[0001] This utility model belongs to the field of well logging data acquisition technology, specifically relating to a well logging data acquisition system with modular access capability and hardware status feedback function. Background Technology
[0002] The well logging data acquisition system is a key piece of equipment used in drilling engineering to obtain downhole working conditions and formation information. It consists of various data acquisition cards, sensors and communication interfaces with different functions, and can acquire parameters such as current, voltage and pulse.
[0003] Existing logging data acquisition equipment mostly adopts manual configuration, with complex connection methods between equipment modules. This not only results in lengthy wiring and high maintenance costs, but also lacks an intuitive feedback mechanism for the working status of each module. Especially when there are a large number of acquisition cards, field engineers often have to manually check the card type and operating status one by one after inserting or replacing the cards, which is inefficient and prone to problems such as inconsistent configurations or slow troubleshooting.
[0004] Therefore, there is an urgent need for a data acquisition device with a compact structure, clear connection method, and the ability to provide hardware status feedback information of the cards, so as to improve the convenience of system deployment and the efficiency of on-site maintenance. Utility Model Content

[0006] The technical solution of this application is as follows:
[0007] A logging data acquisition system with modular access capabilities and hardware status feedback includes a host computer, a communication baseboard, and multiple pluggable data acquisition cards. The communication baseboard has a communication interface and multiple standardized connection slots. The communication baseboard is connected to the host computer through the communication interface, and the multiple standardized connection slots are used to accommodate data acquisition cards of different functional types. Each acquisition card is equipped with an encoding chip, a status indicator light, and an acquisition module. The encoding chip is used to report its device number and type to the host computer, the status indicator light is used to display the real-time operating status of the acquisition card, and the acquisition module is used to acquire current, voltage, and pulse signals related to logging data. The host computer is used to uniformly manage the entire logging data acquisition system and perform data processing and communication scheduling.
[0008] Furthermore, the communication interface is a CAN bus interface.
[0009] Furthermore, the status indicator is an LED indicator, which has three states: green indicates normal operation, red indicates abnormal data acquisition, and off indicates offline or power failure.
[0010] Furthermore, the communication baseboard also has a unified power supply interface.
[0011] Furthermore, the acquisition card supports hot-swapping.
[0012] Compared with the prior art, the present invention has the following beneficial technical effects:
[0013] 1. Modular access design: The acquisition card is plugged into the communication baseboard through a standardized interface, which supports hot-swapping and simplifies the system deployment and replacement process.
[0014] 2. Hardware status feedback mechanism: Each acquisition card is equipped with status display components such as LEDs, which can display the operating status in real time without relying on the host computer interface.
[0015] 3. Encoding chip: The acquisition card integrates a unique encoding chip, which can feed back device identification information to the host computer, improving the ease of system deployment. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the structure of a logging data acquisition system with modular access capability and hardware status feedback function according to this utility model. Detailed Implementation
[0017] To better understand the above-mentioned objectives, features and advantages of this utility model, the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] like Figure 1 As shown, this application provides a logging data acquisition system with modular access capability and hardware status feedback function, including a host computer 1, a communication baseboard 2, and multiple pluggable data acquisition cards 5; the communication baseboard 2 has a communication interface 3 and multiple standardized connection slots 4, the communication baseboard 2 is connected to the host computer 1 through the communication interface 3, and the multiple standardized connection slots 4 are used to accommodate data acquisition cards 5 of different functional types; each acquisition card 5 is equipped with a status indicator light 6, an encoding chip 7, and an acquisition module 8, the status indicator light 6 is used to display the operating status of the acquisition card 5 in real time, the encoding chip 7 is used to report its device number and type to the host computer 1, and the acquisition module 8 is used to acquire current, voltage, and pulse signals related to logging data; the host computer 1 is used to uniformly manage the entire logging data acquisition system and perform data processing and communication scheduling.
[0019] The communication base plate 2 serves as a communication bridge between the host computer 1 and multiple data acquisition cards 5. It is equipped with several standard connection slots 4, each for installing one data acquisition card 5. The data acquisition cards 5 are fixed to the communication base plate 2 via a plug-in / plug-out method, supporting hot-swapping for easy on-site deployment and maintenance. The communication base plate 2 also features a unified power supply interface and a communication interface 3 (e.g., a CAN bus interface).
[0020] Each data acquisition card 5 has a status indicator light 6 (e.g., an LED indicator), an encoding chip 7, and a data acquisition module 8. The status indicator light 6 has three states: green indicates normal operation, red indicates abnormal data acquisition, and off indicates offline or power failure. The encoding chip 7 provides a unique identification code for the data acquisition card 5, which is used to store the data acquisition card type and number for identification in the host computer 1. The data acquisition module 8 is responsible for acquiring signals such as current, voltage, and pulses.
[0021] When the acquisition card 5 is inserted into the connection slot 4 of the communication baseboard 2, the communication link is automatically established. The host computer 1 reads its encoding chip information through the communication interface 3, identifies the card type and number, and monitors the data communication status of each acquisition card 5 through communication detection. It also automatically loads or prompts for setting the corresponding sampling parameters according to preset rules. After identification, the host computer 1 sends configuration information such as sampling frequency, channel range, and filtering parameters to the acquisition card 5, putting it into the acquisition-ready state. If an acquisition card 5 does not respond for an extended period or returns abnormal data, the host computer 1 will issue an alarm on the interface and control the status indicator light of that acquisition card 5 to change color via command, guiding on-site personnel to quickly identify the fault location.
[0022] The system's data acquisition cards are connected via a unified slot, resulting in a compact and clear structure that is easy to install and supports rapid replacement and expansion, significantly improving the deployment efficiency of the logging system. Furthermore, engineers can directly determine the functionality of the data acquisition cards by observing the LED status lights on their surfaces, enhancing fault location efficiency and the intuitiveness of on-site maintenance.
[0023] The embodiments given above are preferred examples of implementing this utility model, and this utility model is not limited to the above embodiments. Any non-essential additions or substitutions made by those skilled in the art based on the technical features of the technical solution of this utility model shall fall within the protection scope of this utility model.
