Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a wireless transceiver device and timing operation method for well site sensor signals. Background Technology

[0002] In traditional well site operations, sensor signal collection relies on wired connections, meaning each sensor needs to be connected to a ground decoding box via one or more cables. This connection method is not only complex but also costly, specifically in the following aspects: 1. Due to the special nature of the well site environment, the distance between the sensor and the decoding box is often far, which increases the required cable length. In some cases, the standard length cable may not be enough to cover the entire distance, which requires the use of an additional cable reel for conversion. This conversion process is not only time-consuming, but also increases the risk of line failure. 2. For well sites with multiple sensors, each additional sensor requires an additional cable, which not only leads to a large amount of cable usage but also makes the wiring extremely complex, increasing the difficulty of maintenance and management. 3. According to the safety regulations of the well site, cables cannot be placed on the ground at will, but need to be hung up or buried underground. This process not only requires additional manpower and resources, but may also extend the construction time. 4. Well site environments are usually harsh, with unpredictable weather conditions and frequent movement of heavy equipment. These factors can cause cables to be scratched, crushed, or damp, thus affecting the stability and accuracy of sensor signals. Damaged cables need to be inspected and replaced regularly, which not only increases maintenance costs but may also cause production interruptions and affect work efficiency. Summary of the Invention

[0003] (a) Technical problems to be solved This invention provides a wireless transceiver device and timing operation method for well site sensor signals, to overcome the problems of cumbersome wired transmission methods and easy damage to wired transmission cables leading to sensor signal loss in the prior art.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides a wireless transceiver device for well site sensor signals, comprising: a wireless sensor host, a wireless transceiver host, a well depth system, and a driller's display; The wireless sensor host and the wireless transceiver host communicate via an antenna. The wireless sensor host is connected to the pressure sensor via a cable. The wireless sensor host transmits the data collected by the pressure sensor to the wireless transceiver host via the antenna. The wireless transceiver host communicates with the well depth system by transmitting signals through an antenna. The well depth system includes: a well depth measuring instrument, a winch sensor, a suspended weight sensor, and a pressure sensor for well depth measurement. The winch sensor is installed on the well site winch and monitors the angular displacement change of the winch shaft. The suspended weight sensor is installed in the well site drilling platform hoisting system and measures the suspended weight of the drill string. The pressure sensor for well depth measurement is installed on the downhole drill string and measures the pressure inside the well. The winch sensor, the suspended weight sensor, and the pressure sensor for well depth measurement are connected to the well depth measuring instrument via cables. The well depth measuring instrument transmits the data collected by the winch sensor, the suspended weight sensor, and the pressure sensor for well depth measurement to the wireless transceiver host via an antenna. The wireless transceiver is connected to the PC via a USB cable. The wireless transceiver transmits the data collected by the well depth measuring instrument and pressure sensor to the PC via the USB cable for calculation. The PC then transmits the calculated data back to the wireless transceiver via the USB cable. The wireless transceiver then sends the calculation results from the PC to the driller's display via an antenna.

[0005] Preferably, the well depth measuring instrument in the well depth system has a built-in antenna, and the well depth system transmits signals to the wireless transceiver host through the well depth measuring instrument.

[0006] Preferably, the wireless sensor host and the wireless transceiver host are each equipped with a wireless transceiver module.

[0008] Preferably, the driller's display includes a wireless receiving module and a display module. The wireless receiving module is used to receive radio frequency signals sent by the wireless transceiver host and demodulate and decode the radio frequency signals to convert them into digital information.

[0009] Preferably, the display module is a TFT liquid crystal display screen, which displays digital information.

[0010] Preferably, the PC host is used to run host computer software.

[0011] Preferably, in the well depth system, the winch sensor is the main sensor, and the suspended weight sensor and the pressure sensor for well depth measurement are compensation sensors. The well depth measuring instrument compensates and corrects the value of the winch sensor through the suspended weight sensor and the pressure sensor for well depth measurement.

[0012] On the other hand, the present invention also provides a timing operation method for a wireless transceiver, including: Step S1: Connect the wireless sensor host to the pressure sensor via a cable. The pressure sensor collects the pressure signal and performs preliminary data calculation and processing. Step S2: Connect the wireless transceiver host to the PC host via a USB cable. The PC host runs the host computer software. After the software starts, it sends the data reading command to the wireless transceiver host via the USB cable. Step S3: After receiving the instruction to transmit via USB cable, the wireless transceiver host modulates the data and transmits it to the wireless sensor host as a 433MHz / 915MHz radio frequency signal. After receiving the signal transmitted by the wireless transceiver host through the antenna, the wireless sensor host transmits the data measured by the well depth system through the well depth measuring instrument. Step S4: The wireless transceiver transmits the data received from the wireless sensor host and the well depth measuring instrument to the PC host via a USB cable. In step S5, the data parsed and calculated by the PC host computer software is sent to the driller's display via a wireless transceiver host.

[0018] like Figure 1-2 As shown, the present invention provides a wireless transceiver device for well site sensor signals, including: a wireless sensor host 2, a wireless transceiver host 3, a well depth system, and a driller's display 5; The wireless sensor host 2 is connected to the pressure sensor 1 via a cable to collect signals from the pressure sensor 1 and convert them into wireless signals, enabling wireless transmission of sensor data. This reduces the use of cables and improves the flexibility and convenience of the system. The wireless sensor host 2 communicates with the wireless transceiver host 3 via an antenna. The wireless sensor host 2 has a built-in signal processing unit and a wireless transmission module, which can perform preliminary processing on the collected signals, including signal amplification, filtering, and analog-to-digital conversion, to ensure signal quality and accuracy. It then transmits the signals to the wireless transceiver host 3 via the antenna. The wireless transceiver host 3 has a built-in signal receiving module and a processing unit, which can demodulate and decode the received signals. Demodulation refers to converting the wireless signal into the original digital signal, while decoding refers to converting the digital signal into a comprehensible data format. Finally, the processed data is transmitted to the PC host 4 via a USB cable. The PC host 4 is used to run the host computer software, which stores, analyzes and manages the data, and provides more comprehensive monitoring and management functions. The wireless transceiver host 3 communicates with the driller's display 5 through the antenna. The driller's display 5 has a built-in wireless receiver. After receiving the signal from the wireless transceiver host 3, the driller's display 5 demodulates and decodes it, and displays the decoded data to the driller through the display screen on the driller's display 5, so that the driller can monitor the well site conditions in real time. The driller's display 5 includes a wireless receiving module and a display module. The wireless receiving module is equipped with an antenna for receiving signals sent by the wireless transceiver host 3. After the received signals are amplified and filtered, they enter the demodulation and decoding stage. The demodulation process converts the radio frequency signal into a baseband signal, and the decoding process restores the baseband signal to the original digital information. The display module is a TFT LCD screen. The display module receives digital information from the wireless receiving module and converts it into information in the form of graphics, text, etc. for display. The wireless sensor host 2 and the wireless transceiver host 3 are each equipped with a wireless transceiver module. The wireless transceiver module integrates digital processing features, which can effectively reduce the burden on the external processor. The wireless transceiver module is not only responsible for sending and receiving signals, but also integrates a FIFO buffer and a TX data register. The FIFO buffer is used to temporarily store the data to be sent, ensuring the integrity and order of the data during transmission. The TX data register is used to store the data to be sent, so that the wireless transceiver module can transmit it at the appropriate time, reducing the risk of data loss and bit errors. The wireless transceiver 3 communicates with the well depth system via an antenna. The well depth system includes a well depth measuring instrument 7, a winch sensor 6, a suspended weight sensor 9, and a well depth measuring pressure sensor 8. The winch sensor 6, suspended weight sensor 9, and well depth measuring pressure sensor 8 are connected to the well depth measuring instrument 7 via cables. In this well depth system, the winch sensor 6 is the main sensor, and the suspended weight sensor 9 and well depth measuring pressure sensor 8 are compensation sensors. The well depth measuring instrument 7 compensates and corrects the value of the winch sensor 6 through the suspended weight sensor 9 and well depth measuring pressure sensor 8. The winch sensor 6 is responsible for detecting the angular displacement change of the winch shaft during drilling to obtain the drilling depth. The suspended weight sensor 9 and well depth measuring pressure sensor 8 act as compensation sensors, compensating and correcting the value of the winch sensor 6 by measuring the suspended weight of the drill string and the pressure in the well to improve the accuracy and reliability of the measurement. The well depth measuring instrument 7 has a built-in antenna, which transmits signals with the wireless transceiver host 3. The well depth system transmits the processed well depth data and other relevant data to the wireless transceiver host 3 through the well depth measuring instrument 7. The wireless transceiver host 3 then transmits the processed data to the PC host 4 via a USB cable. The PC host 4 then transmits the processed data to the driller's display 5 through the wireless transceiver host 3 for real-time monitoring and analysis by relevant personnel. The well depth measuring instrument 7, wireless sensor host 2, wireless transceiver host 3, and driller's display 5 all use the dedicated radio frequency communication chip IA4421 to achieve 433MHz / 915MHz radio frequency communication. The IA4421 chip has high sensitivity and anti-interference capability, which enhances the reliability and stability of the system when working in the complex environment of the well site.

[0019] The following is a detailed description of the timing operation method of a wireless transceiver device for well site sensor signals.

[0020] Step S1: Connect the wireless sensor host 2 to the pressure sensor 1 via a cable. The pressure sensor 1 collects the pressure signal and performs preliminary data calculation and processing. Step S2: Connect the wireless transceiver host 3 to the PC host 4 via a USB cable. The PC host 4 runs the host computer software. After the software starts, it sends the data reading command to the wireless transceiver host 3 via the USB cable. Step S3: After receiving the instruction to transmit via USB cable, the wireless transceiver host 3 modulates the data and transmits it to the wireless sensor host 2 as a 433MHz / 915MHz radio frequency signal. After receiving the signal transmitted by the wireless transceiver host 3 through the antenna, the wireless sensor host 2 transmits the data measured by the well depth system through the well depth measuring instrument 7. Step S4: The wireless transceiver host 3 transmits the data received from the wireless sensor host 2 and the well depth measuring instrument 7 to the PC host 4 via a USB cable. In step S5, the data parsed and calculated by the PC host software is sent to the driller's display 5 via the wireless transceiver host 3.
