Problems solved by technology

[0004] At present, for the real-time data acquisition and transmission of the comprehensive mud logging instrument, the acquisition and transmission software is generally installed and run on the industrial computer to realize, for example: the author is "Wu Zhengping", the source of the document is "automated instrumentation", and the publication date is 1999 The 6th Chinese periodical document, which discloses a periodical document titled "Comprehensive Mud Logging Data Real-time Acquisition Program Design", which involves introducing how to use Microsoft Visual C++ to design a comprehensive mud logging data real-time acquisition program. The hardware composition of the comprehensive mud logging instrument and the main steps and subroutines of the comprehensive mud logging data real-time acquisition program are designed with Microsoft Visual C++, but the above software is installed on the industrial computer, which has the advantages of high price, large volume, heavy weight, and easy virus infection , relatively complex operation; but never applied ARM single-chip microcomputer to this field, and changed the deficiencies of the above-mentioned industrial computer

Embodiment 1

[0024] Such as figure 1 As shown, the present invention includes an ARM single-chip microcomputer, real-time data acquisition and early warning software, and data transmission software. ARM microcontroller is composed of circuit board, ARM chip, RS232 serial port, two network ports, embedded operating system, touch screen, power switch and shell; ARM chip, RS232 serial port, two network ports are integrated on the circuit board ; Above the single chip computer hardware is the embedded operating system of Windows CE; then upwards is the loaded mud logging real-time data acquisition software and data transmission software.

Embodiment 2

[0026] Such as figure 2 As shown, the real-time data acquisition process is started. Firstly, the real-time data stream is captured from the port of the comprehensive mud logging unit, then parsed into a unified format, and filled into the early-warning processing process. The data and early warning results are sent to the message middleware sub-node for transmission; the whole process is repeated, that is, the real-time data collection and early warning functions are realized; finally, the message middleware sub-node uses different transmission channels to transmit to the base end, if the transmission channel is abnormal , the local data cache is realized, and after the transmission channel is normal, the data is transmitted to the base terminal by using the breakpoint resume function.

Embodiment 3

[0028]As a preferred embodiment of the present invention, the present invention includes an ARM single-chip microcomputer; the ARM single-chip microcomputer is loaded with a real-time data acquisition and early warning module for collecting real-time data at the well site and performing early warning, and reporting the well site business data for collecting the well site business data The module is connected with the real-time data collection and early warning module and the well site business data reporting module, and receives the well site real-time data and early warning results, as well as the message middleware sub-node receiving the well site business data, and the message middleware sub-node The node is connected to and receives the message middleware parent node of the data packet sent by the message middleware child node, and the message middleware parent node is connected to the base end. Data is transmitted between the message middleware child node and the message m...

Abstract

The invention discloses a real-time data acquisition transmission instrument aiming at a comprehensive logging instrument, and relates to the fields of real-time data acquisition and real-time data transmission of comprehensive logging instrument ports. The real-time data acquisition transmission instrument comprises an ARM singlechip, wherein a real-time data acquisition and early-warning module for acquiring real-time data of a well field and performing early warning, a well-field service data report module for acquiring service data of the well field, a message middleware child node which is connected with the real-time data acquisition and early-warning module and the well-field service data report module and is used for receiving the real-time data and early-warning result of the well field and receiving the service data of the well field and a message middleware father node which is connected with the message middleware child node and is used for receiving a data packet sent by the message middleware child node are loaded on the ARM singlechip; and the message middleware father node is connected to the base end. The real-time data acquisition transmission instrument is small in volume, low in cost and light in weight; and the instrument is insusceptible to infection with viruses and can be operated simply.

Description

technical field [0001] The invention relates to the field of real-time data collection and transmission at ports of comprehensive mud logging instruments, in particular to a real-time data collection and transmission device based on an ARM single-chip microcomputer, which can ensure stable, reliable, timely and safe collection and transmission of a large amount of real-time data. Background technique [0002] Oil well sites are scattered in the wild, with harsh environments and poor network communication and traffic conditions. In the process of oil drilling, a large amount of valuable data is generated, especially the real-time logging data collected by the integrated mud logging instrument, because they are the data source of oil drilling geological prediction, engineering prediction, geological analysis, single well evaluation, and regional evaluation . If they are remotely transmitted to the base center in real time, the superior conditions of various experts and high-p...
