Description

Technical Field

[0001] This utility model belongs to the technical field of logging acquisition boxes, and particularly relates to a field acquisition box for a logging system. Background Technology

[0002] The logging system field acquisition box is an important logging device used to collect data from various sensors on site, such as winch sensors, temperature sensors, pump flushing sensors, and weight sensors. By collecting sensor data, the system can monitor the on-site working conditions in real time, providing an important guarantee for safe drilling.

[0003] Currently, existing logging acquisition boxes collect a limited number of sensor signals and cannot accurately determine the data source. When multiple sensor data need to be collected on-site, multiple acquisition boxes need to be deployed, which not only increases costs but also makes the entire logging system larger and more complex in determining the data source. Utility Model Content

[0004] The purpose of this invention is to solve the problems of limited sensor signal types, insufficient data acquisition quantity, and inadequate data sources in existing logging acquisition boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A field acquisition box for a logging system includes: an acquisition box body and an acquisition box bottom plate disposed inside the acquisition box body; The data acquisition box base plate is equipped with a CAN communication interface, a power interface, acquisition modules, an acquisition module ID switch, and a base plate ID switch. The CAN communication interface and power interface are located on the left side of the data acquisition box base plate, while the acquisition module ID switch and base plate ID switch are located on the right side. The acquisition modules are arranged sequentially in the middle of the data acquisition box base plate. The acquisition modules are compatible with current acquisition cards and voltage / pulse acquisition cards. The acquisition module ID switch is used to set the acquisition module ID, and the base plate ID switch is used to set the data acquisition box base plate ID.

[0006] Furthermore, the data acquisition box has 16 sensor interfaces.

[0007] Furthermore, there are four data acquisition modules.

[0008] Furthermore, a data acquisition module ID and a data acquisition box base plate ID together form a 7-bit binary ID, which can identify the data of 128 data acquisition cards and 32 data acquisition boxes.

[0009] The beneficial effects of this utility model are as follows: A single data acquisition box can simultaneously accommodate current acquisition cards and voltage / pulse acquisition cards, enabling the simultaneous acquisition of data from current, pulse, and voltage sensors. By toggling different ID switches, the ID of each data entry can be set, allowing the host computer to read the ID and thus determine the data source. Attached Figure Description

[0012] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0013] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0014] A field acquisition box for a logging system includes an acquisition box body 4, an acquisition box base plate 5 inside the acquisition box body 4, a CAN communication interface 2, a power interface 3, four acquisition modules 6, an acquisition module ID switch 7, and a base plate ID switch 8. The four acquisition modules 6 are compatible with current acquisition cards and voltage / pulse acquisition cards. The acquisition module ID switch 7 is used to set the IDs of the four acquisition modules, and the base plate ID switch 8 sets the base plate ID of the acquisition box.

[0015] The CAN communication interface 2 and power interface 3 are located on the left side of the acquisition box base plate 5, the acquisition module ID switch 7 and the base plate ID switch 8 are located on the right side of the acquisition box base plate 5, and the acquisition modules 4 are arranged in the middle of the acquisition box base plate 5.

[0016] Specific examples Figure 1 and Figure 2As shown, the acquisition box 4 has 16 sensor interfaces 1, enabling simultaneous data acquisition from 16 sensors. The acquisition box sends data to the centralized data acquisition box via the CAN communication interface 2, and the entire box is powered through the power port 3. Sensors are connected to the sensor interfaces 1 of the field acquisition box, and then connected to the acquisition modules 6 via the sensor interfaces 1. The acquisition modules 6 are divided into current acquisition cards and voltage / pulse acquisition cards. Both types of acquisition modules 6 are connected to the acquisition box base plate 5 via a plug-in method. The acquisition box base plate 5 communicates with the centralized data acquisition box via the CAN communication interface 2, and the centralized data acquisition box then sends the data to the host computer for real-time monitoring.

[0017] Specifically, when collecting sensor data, different acquisition modules are used depending on the type of sensor output signal. All four acquisition modules 6 on the base plate 5 of the acquisition box are compatible with both current acquisition cards and voltage / pulse acquisition cards. When collecting current signals, all four acquisition modules 6 on the base plate 5 are equipped with current acquisition cards; when collecting voltage and pulse signals, all four acquisition modules 6 on the base plate 5 are equipped with voltage / pulse acquisition cards; when collecting current, voltage, and pulse signals, the appropriate number of current acquisition cards and voltage / pulse acquisition cards are installed according to the number of signals to be collected.

[0018] Specific examples Figure 4 As shown, the four acquisition module ID switches 7 correspond one-to-one with the four acquisition modules 6. Each acquisition module ID switch 7 sets the ID of one acquisition module 6. The five acquisition box base plate ID switches 8 set the acquisition box base plate ID. The acquisition module ID and the acquisition box base plate ID together form a 7-bit binary ID. In total, the data of 128 acquisition modules 6 and 32 acquisition boxes can be identified. In the host computer, the source of the data is determined by reading the 7-bit binary ID, so as to realize real-time and accurate monitoring of the on-site working conditions.
