Description

Technical Field

[0001] This invention belongs to the field of Internet of Things (IoT) technology for petroleum equipment, specifically relating to a dynamic data acquisition and transmission system for the edge of oil drilling rigs, and a method for dynamic data acquisition and transmission using the aforementioned dynamic data acquisition and transmission system for the edge of oil drilling rigs. Background Technology

[0002] Oil drilling rigs are complex oil drilling equipment composed of various devices. The Internet of Things (IoT) system for these rigs monitors numerous devices, resulting in an enormous volume of data collected. Furthermore, drilling rigs often operate in remote areas across the country, and data transmission from the edge of the IoT system to the cloud platform primarily relies on 4G wireless networks. However, the current data collection volume is large, and the real-time requirements are high; a single rig can collect billions of data points per month, leading to high performance requirements for edge data acquisition equipment, large data transmission volumes, and significant data storage pressure on the cloud platform. Therefore, this paper proposes a new IoT system for drilling rigs to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a dynamic data acquisition and transmission system for the edge of oil drilling rigs, which solves the technical problems of large data acquisition volume, large transmission bandwidth consumption, and large data storage capacity in the prior art.

[0004] Another objective of this invention is to provide a method for dynamic data acquisition and transmission using the aforementioned oil drilling rig edge data dynamic acquisition and transmission system.

[0005] The first technical solution adopted in this invention is a dynamic data acquisition and transmission system for the edge of an oil drilling rig, including an acquisition timing module, an acquisition rule discrimination module connected to an acquisition rule discrimination module via a signal, a data acquisition module connected to a data acquisition module via a signal, a protocol management module connected to a protocol management module via a signal, a transmission rule discrimination module and a data transmission module connected to the protocol management module via signals, and a transmission rule discrimination module and a transmission timing module connected to the transmission rule discrimination module via signals.

[0006] The data transmission module is also connected to the cloud platform via signal, and the data acquisition module is also connected to the drilling equipment via signal.

[0007] The second technical solution adopted in this invention is to utilize the aforementioned dynamic acquisition and transmission system for edge data of oil drilling rigs, and the specific steps are as follows:

[0008] S1. The dynamic data acquisition and transmission program at the edge of the oil drilling rig loads all data acquisition and transmission rules.

[0009] S2. The data acquisition module performs the first data acquisition. After the data is processed by the protocol management module, it is transmitted to the transmission rule discrimination module and recorded as the original value. The data transmission module executes a transmission procedure once.

[0010] S3. The data collection rule judgment module generates a collection list. The data collection module performs a second data collection based on the collection list and transmits it to the protocol management module. The protocol management module processes the data and transmits it to the transmission rule judgment module to obtain the second collection data.

[0011] S4. Compare the second collected data with the original value, obtain the data that can be transmitted, and replace the original value to obtain a new original value;

[0012] S5. The transmission timing module refreshes the maximum transmission timestamp of the new original value. The data transmission module executes a transmission procedure on the new original value and determines whether to obtain the receiving flag returned by the cloud platform. If no receiving flag is received from the cloud platform, the data is cached and the transmission procedure is executed periodically until the receiving flag is obtained from the cloud platform.

[0013] The invention is further characterized by:

[0014] The data acquisition and transmission rules in S1 include data name, data address, acquisition period, minimum range value, maximum range value, transmission threshold, maximum transmission interval, acquisition communication protocol, and transmission communication protocol.

[0015] The data acquisition timing module loads the acquisition cycle, the data acquisition module loads the data address and acquisition communication protocol, the transmission rule discrimination module loads the transmission threshold, data name, minimum range value and maximum range value, the transmission timing module loads the maximum transmission interval, and the data transmission module loads the transmission communication protocol.

[0016] The acquisition period is set to an integer multiple of the minimum acquisition period; the transmission threshold is set to a positive number and must not exceed the absolute value of the difference between the maximum and minimum data range; the maximum transmission interval is set to an integer multiple of the acquisition period.

[0017] The specific method for S2 is as follows:

[0018] The data acquisition module collects all data for the first time and transmits all data to the protocol management module in the form of data packets for the first time. The protocol management module decodes the first data packets according to the acquisition communication protocol and transmits the decoded data to the transmission rule judgment module. The transmission rule judgment module records the first collected data as the original value, and the data transmission module executes a transmission procedure.

[0019] The specific method for S3 is as follows:

[0020] S3.1 The transmission timing module refreshes the maximum data transmission timestamp and sends the maximum transmission interval to the transmission rule discrimination module;

[0021] S3.2 The data collection timing module determines whether the data collection time has expired. If it has expired, it refreshes the data collection timestamp and sends it to the data collection rule discrimination module.

[0022] S3.3 The data collection rule judgment module determines whether to collect data based on the data collection timestamp. If the data collection time has arrived, the data is added to the collection list and the collection list is sent to the data collection module. The data collection module executes the collection procedure once for all the data in the collection list and sends the collected data to the protocol management module a second time in the form of data packets.

[0023] S3.4 The protocol management module decodes the second data packet and sends the decoded data to the transmission rule discrimination module. The transmission rule discrimination module compares the second collected data with its original value to determine whether the current data needs to be transmitted and obtains the data that needs to be transmitted as the new original value.

[0024] The specific method for determining whether current data needs to be transmitted in S3.4 is as follows:

[0025] If the absolute value of the difference between the second collected data and the original value is greater than or equal to the transmission threshold, the transmission rule discrimination module will add the second collected data to the transmission list and replace the original value with the second collected data as the new original value.

[0026] If the absolute value of the difference between the second collected data and the original value is less than the transmission threshold, the transmission rule discrimination module will detect the maximum transmission interval. If the maximum transmission interval has not been reached, S3.2 will be executed. If the maximum transmission interval has been reached, the transmission rule discrimination module will add the second collected data to the transmission list and replace the original value with the second collected data as the new original value.

[0027] The specific method for S5 is as follows:

[0028] S5.1 The transmission timing module refreshes the maximum transmission timestamp of the data added to the transmission list and sends the new maximum transmission timestamp to the transmission rule discrimination module;

[0029] S5.2 The protocol management module encodes the data added to the transmission list, the data transmission module executes the transmission procedure once, and returns to the execution step S3.3;

[0030] S5.3 The data transmission module determines whether it has obtained the receiving flag sent by the cloud platform. If it has not received the receiving flag sent by the cloud platform, it caches the data and executes the transmission program once periodically until it obtains the receiving flag sent by the cloud platform.

[0031] The beneficial effects of this invention are:

[0032] (1) The data acquisition and transmission system of the present invention adjusts the data acquisition cycle according to the sensitivity of data changes, which effectively reduces the data acquisition pressure and the performance requirements of data acquisition equipment.

[0033] (2) The data acquisition and transmission system of the present invention adjusts the data transmission decision conditions according to the sensitivity of data changes, which greatly reduces the data transmission traffic and the data storage capacity requirements of the platform.

[0034] (3) The present invention incorporates the maximum data transmission time interval as a data transmission guarantee element into the data acquisition and transmission system to ensure the data integrity on the cloud platform.

[0035] (4) The present invention incorporates a response mechanism and a breakpoint resume mechanism during the data transmission process of the data acquisition and transmission system to ensure that data is not lost during transmission;

[0036] (5) The data acquisition and transmission system of the present invention can realize dynamic data acquisition and data compression transmission while ensuring that the data on the cloud platform of the Internet of Things system of oil drilling rig is not distorted. This can greatly reduce the performance requirements of edge data acquisition equipment, save data transmission traffic, and save data storage capacity on the platform. Attached Figure Description
