[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Combine the following Figure 1-Figure 4 A remote monitoring and maintenance system of the present invention is described.

[0050] Figure 1 is an architecture diagram of the remote monitoring and maintenance system provided in this embodiment, such as Figure 1 As shown, a remote monitoring and maintenance system provided in this embodiment includes: a plurality of field acquisition devices, a monitoring terminal and a cloud platform; each of the field acquisition devices and the monitoring terminal is communicatively connected to the cloud platform;

[0051] On-site collection equipment, used to collect its own equipment data information, and in the event of a failure, send a fault code obtained based on the analysis of the equipment status information to the cloud platform;

[0052] The device data information is data information obtained by the field acquisition device collecting multiple data points of the device, and the device data information includes the device status information, which is used by the field acquisition device to perform its own device status analysis;

[0053] The cloud platform is used to call the fault information library pre-stored in the cloud platform through the fault code to obtain the analysis result, and send the analysis result to the on-site acquisition device and the monitoring terminal respectively;

[0054] The fault information library is used to pre-store multiple types of fault codes and the fault causes and fault solutions corresponding to each type of fault code; the analysis results include the fault causes and fault solutions of the field acquisition equipment that has failed;

[0055] The monitoring terminal is used to receive the analysis result sent by the cloud platform.

[0056] It should be noted that, taking oil and gas drilling operations as an example, such operations are usually carried out in remote field environments. Once equipment fails, it is difficult for equipment maintenance experts to rush to the scene in the first place. Therefore, remote monitoring of the operating status of field operation equipment and fault diagnosis are of great practical significance.

[0057] The system provided in this implementation realizes the interaction between the field acquisition equipment, the monitoring terminal and the cloud platform. This embodiment takes the drilling scenario as an example for explanation. Figure 1 For example, in a drilling operation, the field acquisition equipment may be a plurality of iron roughnecks distributed in a preset area, and the field drilling operation may be performed. The plurality of iron roughnecks may respectively realize communication connection with the cloud platform, and each iron roughneck may display a fault through a local HMI (Human Machine Interface); the monitoring terminal may be a computer device, such as a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc., and this embodiment does not impose any special limitation on this. The monitoring terminal realizes communication connection with the cloud platform, and remote users such as drilling experts may view the operation status of the equipment through the monitoring terminal.

[0058] Specifically, each field acquisition device is equipped with multiple data collection points for collecting its own equipment data information. The equipment data information may include basic information about the equipment, such as the company to which the equipment belongs, the well team to which it belongs, the model and serial number, etc., to identify the current equipment; it may also include equipment status information, such as the operating time of a component of the equipment or the current rotation angle of a component, etc. The equipment can determine whether a fault has occurred based on the equipment status information.

[0059] In one embodiment, when the field acquisition device is operating normally, it will send the device data information to the cloud platform, and the storage and management of the data of the monitored field acquisition device will be realized through the storage space and dynamic expansion function of the cloud platform. Since the device data information sent to the cloud platform includes basic device information and device status information, the cloud platform determines the unique corresponding field acquisition device based on the basic device information, and stores the device status information accordingly, thereby realizing the standardized storage of device data information.

[0060] Specifically, the on-site collection equipment can collect and send equipment data information to the cloud platform in real time; or upload equipment data information to the cloud platform once every cycle, for example every hour, so that the cloud platform can analyze the current status of the equipment based on the latest uploaded equipment data information.

[0061] Furthermore, after receiving the equipment data information, the cloud platform can also predict the future operating status of the corresponding on-site acquisition equipment based on the equipment status information. For example, based on the current status of a component, it can determine whether the equipment will stop running due to damage to the component and replace the component in time; or determine whether a component needs to be adjusted in angle to improve equipment operation efficiency, etc., so as to achieve the prediction of equipment failures and better maintain the system.

[0062] Further, Figure 2 is a schematic diagram of data visualization analysis provided by this embodiment, such as Figure 2 As shown in the figure, after the cloud platform predicts the future operating status of the corresponding field acquisition equipment based on the equipment status information, the prediction results can be sent to the monitoring terminal so that the remote user can intuitively view the prediction results; the visualization interface obtained based on the equipment status information can also be sent to the monitoring terminal, see Figure 2 , shows the status of the upper clamp, middle clamp and lower clamp in a certain period of time, which are represented by test1, test2 and test3 respectively. The remote user of the monitoring terminal can directly observe the data correlation, find abnormal values, and assist in fault analysis.

[0063] In another embodiment, when a field acquisition device fails, the field acquisition device determines the fault phenomenon based on the device status information collected by itself, further obtains a fault code, and sends the fault code to the cloud platform. The fault phenomenon may include the specific failed component.

[0064] It should be noted that the cloud platform is provided with a fault information library, which pre-stores various types of fault codes and the fault causes and fault solutions corresponding to each type of fault code. The fault information library is called through the fault code to determine the corresponding fault cause and fault solution based on the fault phenomenon. For example, if the on-site acquisition device determines that the fault phenomenon is "fault in the punch cylinder", it further obtains the fault code corresponding to the fault phenomenon and sends the fault code to the cloud platform. The cloud platform calls the fault information library through the fault code to confirm that the fault cause is "the punch cylinder is not at zero position" and confirms that the fault solution is "adjust the punch cylinder to zero position". The fault phenomenon and the corresponding fault cause and fault solution are sent to the on-site acquisition device and monitoring terminal where the fault occurs.

[0065] The above is an explanation of a remote monitoring and maintenance system provided by the present invention. The remote monitoring and maintenance system provided by the present invention includes: multiple field acquisition devices, monitoring terminals and cloud platforms; each field acquisition device and monitoring terminal are connected to the cloud platform in communication; the field acquisition device is used to collect its own equipment data information, and in the case of a failure, the fault phenomenon obtained by analyzing the equipment status information is sent to the cloud platform; wherein the equipment data information is the data information obtained by the field acquisition device collecting multiple data points of itself, and the equipment data information includes equipment status information, and the equipment status information is used for the field acquisition device to perform its own equipment status analysis; the cloud platform is used to call the fault information library pre-stored in the cloud platform through the fault code based on the fault phenomenon to obtain the analysis result, and send the analysis result to the field acquisition device and the monitoring terminal respectively; wherein the fault information library is used to pre-store multiple types of fault codes and the fault causes and fault solutions corresponding to each type of fault code, and the analysis result includes the fault cause and fault solution of the field acquisition device that has failed. It can be seen that the present invention is based on the architecture of field acquisition device-cloud platform-monitoring terminal, which can realize remote monitoring of the operating status of the field acquisition device, and timely perform remote fault diagnosis and provide solutions when a fault occurs.

[0066] Based on the above embodiment, in this embodiment, the field acquisition device is also used to send its own device data information to the cloud platform when it is operating normally;

[0067] The cloud platform is also used to receive device data information respectively sent by multiple field acquisition devices to monitor the multiple field acquisition devices.

[0068] Specifically, when the field acquisition equipment is operating normally, it will send the equipment data information to the cloud platform. Through the storage space and dynamic expansion function of the cloud platform, the data of the monitored field acquisition equipment can be stored and managed. Since the equipment data information sent to the cloud platform contains basic equipment information and equipment status information, the cloud platform determines the unique corresponding field acquisition equipment based on the basic equipment information, and stores the equipment status information accordingly, thereby realizing the standardized storage of equipment data information.

[0069] For example, the basic information of the equipment may be "Company: XXX Oil Company; Well Crew: XX Well Crew; Model: CN-10000; Equipment Serial Number: 20232023", and the corresponding equipment may be located based on the basic information of the equipment.

[0070] The remote monitoring and maintenance system provided in this embodiment enables the field acquisition device to send its own device data information to the cloud platform when it is operating normally, so that the cloud platform can monitor multiple field acquisition devices after receiving the device data information sent by multiple field acquisition devices respectively.

[0071] Based on the above embodiment, in this embodiment, the system further includes a PLC controller, and the PLC controller is connected to the field acquisition device;

[0072] The PLC controller is used to control the field acquisition equipment to generate the equipment data information.

[0073] Based on the above embodiment, in this embodiment, each of the field collection devices is provided with a data collector;

[0074] The data collector is used to collect the device data information of the field acquisition device generated by the PLC controller in real time, and send the device data information of the field acquisition device to the cloud platform when the field acquisition device operates normally.

[0075] It should be noted that the number of data points of the equipment data information of the field acquisition device generated by the PLC controller is greater than 5000; the frequency of the data collector to collect the equipment data information of the field acquisition device generated by the PLC controller in real time is 500ms / time.

[0076] In one embodiment, the data collector is also used to send the failure phenomenon of the field collection device to the cloud platform when the field collection device fails.

[0077] The remote monitoring and maintenance system provided in this embodiment collects the equipment data information of the field collection equipment generated by the PLC controller in real time through the data collector, thereby realizing high-frequency data collection and cloud platform transmission.

[0078] Based on the above embodiment, in this embodiment, the field acquisition device is further provided with a fault tree program;

[0079] The fault tree program is used to compare and analyze the device status information of the field acquisition device with the local information library pre-stored in the fault tree program when the field acquisition device fails, so as to determine the fault code, and send the fault code to the cloud platform;

[0080] The local information database is used to pre-store a plurality of equipment states and the fault codes corresponding to each equipment state.

[0081] It should be noted that each field acquisition device is provided with a fault tree program. The fault tree program can run a local information base. The local information base pre-stores a variety of device states and the fault codes corresponding to each device state. The local information base is run through the fault tree program to determine the fault code based on the device state information.

[0082] Specifically, when a field acquisition device fails, the field acquisition device determines the fault phenomenon based on the device status information collected by itself, further determines the fault code, and sends the fault code to the cloud platform. The fault phenomenon may include the specific component that has failed. For example, the fault phenomenon may be "failure of the punch cylinder", "failure of the make-up and break-out buckle", etc.

[0083] The remote monitoring and maintenance system provided in this embodiment determines the fault phenomenon through the on-site acquisition equipment itself, and sends the fault phenomenon to the cloud platform, and then analyzes the fault cause and fault solution through the cloud platform to realize remote fault diagnosis of the on-site acquisition equipment.

[0084] Based on the above embodiment, in this embodiment, the monitoring terminal is further used to send guidance information to the cloud platform within a preset time period based on the analysis result sent by the cloud platform;

[0085] Wherein, the guidance information is used to instruct the cloud platform to adjust the analysis result;

[0086] The cloud platform is further configured to adjust the analysis result based on the guidance information when receiving the guidance information returned by the monitoring terminal within a preset time period, and send the adjusted analysis result to the on-site acquisition device;

[0087] The on-site collection equipment is also used to confirm that the adjusted analysis result is the final analysis result.

[0088] The cloud platform is further configured to send a confirmation message to the on-site acquisition device if the guidance information returned by the monitoring terminal is not received within a preset time period;

[0089] The confirmation information is used to instruct the on-site acquisition device to confirm that the analysis result is the final analysis result;

[0090] The on-site collection device is further used to confirm that the analysis result is a final analysis result based on the confirmation information.

[0091] It should be noted that the monitoring terminal is also used to display the target field collection device and the device data information of the target field collection device through a visual interface after the cloud platform determines the target field collection device according to the basic information of the device.

[0092] Specifically, after the cloud platform sends the analysis results to the monitoring terminal, users such as remote experts of the monitoring terminal can further analyze the failed on-site acquisition equipment based on the visualization page to confirm whether to adjust the analysis results.

[0093] If within the preset time period, for example, within 1 hour after the cloud platform sends the analysis results to the monitoring terminal, if the remote user makes adjustments to the analysis results, the cloud platform sends guidance information to the cloud platform through the monitoring terminal. After the cloud platform adjusts the analysis results based on the guidance information, the adjusted analysis results are sent to the on-site collection equipment, so that the on-site personnel can adjust the equipment in time according to the adjusted analysis results.

[0094] If the remote user does not issue any instructions within the preset time, for example, within 1 hour after the cloud platform sends the analysis results to the monitoring terminal, the cloud platform sends a confirmation message to the on-site collection device so that the on-site personnel can adjust the equipment in time according to the analysis results.

[0095] Optionally, a remote user of the monitoring terminal can also directly send instructions to confirm the analysis results without waiting for a preset period of time for automatic sending via the cloud platform, thereby improving diagnostic efficiency.

[0096] The remote monitoring and maintenance system provided in this embodiment improves the accuracy and efficiency of fault diagnosis by sending the analysis results to the on-site acquisition equipment and the monitoring terminal respectively, and then performing further analysis through the monitoring terminal.

[0097] Based on the above embodiment, in this embodiment, the device data information also includes basic device information, and the cloud platform determines the target field acquisition device through the basic device information; the device status information includes the use cycle of multiple components constituting the field acquisition device;

[0098] The cloud platform is further used to determine the target field collection device according to the basic information of the device after receiving the device data information respectively sent by the plurality of field collection devices;

[0099] Determine whether the use period of the components of the target scene acquisition equipment reaches the corresponding preset period;

[0100] When the service life of the component is greater than or equal to the corresponding preset period, sending a prompt message to the monitoring terminal to prompt the user to replace the component;

[0101] The monitoring terminal is further used to receive the prompt information sent by the cloud platform;

[0102] The cloud platform is also used to repeatedly execute the step of determining whether the usage cycle of the components of the target scene acquisition device has reached the corresponding preset cycle until the multiple components constituting the target scene acquisition device are determined to be complete.

[0103] Specifically, the equipment data information may include basic information about the equipment, such as the company to which the equipment belongs, the well team to which it belongs, the model and serial number, etc., to identify the current equipment; it may also include equipment status information, such as the operating time of a component constituting the equipment or the current rotation angle of a component, etc. The equipment status information also includes the usage cycles of multiple components constituting the field acquisition equipment, for example, recording that the current buckled drill pipe has been in use for 10 days.

[0104] Specifically, since the equipment will upload equipment data information to the cloud platform in real time or periodically when the equipment is operating normally, the cloud platform can monitor and maintain multiple field acquisition devices based on the equipment data information.

[0105] In a specific embodiment, after the cloud platform determines the target scene acquisition device based on the basic information of the device, each component constituting the target scene acquisition device is detected.

[0106] For example, if the preset period of the make-up drill rod is 10 days, if the equipment status information of the target field acquisition device is analyzed to show that the current make-up drill rod has been used for 10 days, a prompt message is sent to the monitoring terminal. Each component constituting the target field acquisition device needs to be tested. After the test is completed, the test of the target field acquisition device is completed, and then the test of the next field acquisition device is carried out until all connected field acquisition devices are tested.

[0107] The remote monitoring and maintenance system provided in this embodiment realizes real-time monitoring and maintenance of on-site acquisition equipment through a cloud platform, and has a simple architecture and high practicality.
