Problems solved by technology

At present, the traditional measurement-while-drilling system for drilling rigs consists of an underground transmitting part and a ground receiving part. The cost is relatively low and it is easy to implement. Signal error makes the data information obtained by the drilling rig measurement system inaccurate
In the drilling rig measurement system, the inertial sensor is a frequently used measurement method, but the inertial sensor is easily disturbed by vibration, magnetic field, temperature, etc., which will lead to inaccurate data information or even failure

Abstract

The invention provides a measurement while drilling system for a drill carriage. The measurement while drilling system comprises a sensor module, a signal rod, a central processing unit (CPU) module and a display, wherein the sensor module comprises a three-axis acceleration meter, a three-axis gyroscope, a three-axis magnetometer, a temperature sensor and a current sensor; the signal rod comprises a digital signal processor (DSP) and a power supply module; the DSP comprises a power supply interface connected with the power supply module and a communication interface module connected with the sensor module; the CPU module comprises a controller area network (CAN) serial communication interface and a field bus interface; and the field bus interface is connected with a main control platform of the drill carriage. The measurement while drilling system for the drill carriage provided by the invention can be used for accurately positioning a drill of the drill carriage in real time; the accuracy of the obtained data information is good; the reliability is high; and the measurement while drilling system has a strong implementable property, and is suitable for a severe field environment with strong vibration and large torque.

Description

technical field [0001] The invention relates to a drilling rig measuring system while drilling. Background technique [0002] Drilling rig measurement while drilling system is widely used in oil exploration, pipeline laying, underground excavation and other equipment. At present, the traditional measurement-while-drilling system for drilling rigs consists of an underground transmitting part and a ground receiving part. The cost is relatively low and it is easy to implement. The signal error makes the data information obtained by the drilling rig measurement system inaccurate. Inertial sensors are commonly used measurement methods in the drilling rig measurement system, but the inertial sensors are easily disturbed by vibration, magnetic field, temperature, etc., which will lead to inaccurate data information or even failure. Contents of the invention [0003] The present invention overcomes the above disadvantages and provides a drilling rig measuring system capable of a...
