Description

Technical Field

[0001] The present invention relates to the technical field of pressure monitoring, and in particular to a pressure detection system that can be used for outdoor wireless data transmission. Background Art

[0002] In the field of petrochemicals, the production process involves relatively high high pressures, ranging from more than ten MPa to several hundred MPa. In the production system, after the new pipeline is installed or the old pipeline is removed and replaced with a new one, a pressure holding test is required before the formal production to simulate whether the pipeline will leak during normal production. The pressure holding test is to increase the pressure in the pipeline to the critical upper limit of the pipeline pressure to see whether the pipeline will leak. If a leak occurs, the pipeline needs to be repaired and the leak point confirmed. If the pipeline does not leak, it proves that the pipeline is installed or repaired well and can be put into formal use.

[0003] Pressure holding tests are generally used in industrial sites. Since pressure holding tests involve safety hazards, people often need to stay away from the pressure holding test site. Currently, high-precision pressure gauges are mainly used on site, and high-definition cameras are equipped to detect changes in pressure gauge readings. The high-definition camera is powered by a power supply and communicates with the network through shielded twisted pair cables. Workers observe changes in the pointer pressure gauge through the camera in a safe area. Since high-voltage safety operations are involved, observers need to be in a safe area 80 meters away from the site to view changes in pressure gauge data through the camera, and they need to record changes in pressure gauge pressure over time.

[0004] In the above traditional pressure holding test, there are the following problems:

[0005] 1. Industrial sites generally lack power, so when cameras need power, the power cables required are very long, potentially hundreds of meters long. Furthermore, due to the constraints of on-site space and the environment, wiring is not easy, takes a long time, is inefficient, and poses certain safety risks.

[0006] 2. Industrial sites currently use high-definition cameras for observation, and shielded twisted-pair cables for data communication. Because there are many high-power motors involved in the site, the frequent start and stop of the motors will cause electromagnetic interference to cause nearby signals to attenuate or be lost. Once the signal is lost, the data will be inaccurate or the pressure data within the lost period will be completely lost. The validity of the data cannot be guaranteed, which will lead to the failure of the pressure holding test.

[0007] 3. Due to the high requirements on the time and pressure curve of the pressure gauge on site, it is necessary to record the pressure change curve over time. Currently, people record data manually to complete the drawing of the pressure time change curve. This method is relatively backward and inaccurate. Summary of the Invention

Thus, the appearances of the phrases "in one embodiment," "in an embodiment," "an example," or "an example" in various places throughout this specification are not necessarily all referring to the same embodiment or example. Furthermore, the particular features, structures, or characteristics may be combined in any suitable combinations and / or subcombinations in one or more embodiments or examples.

[0030] It should be noted that, unless otherwise specified, the technical terms in this embodiment have the common meanings understood in the relevant technical field.

[0031] Please refer to Figures 1 to 2 An embodiment of the present invention provides a pressure detection system that can be used for outdoor wireless data transmission. The pressure detection system includes a power module and an intelligent controller; wherein the power module includes a rechargeable lithium battery; the intelligent controller is equipped with a wireless communication module and a cache module; the wireless communication module includes a first communication module and a second communication module;

[0032] The first communication module is used to receive pressure data transmitted by the pressure monitoring device; wherein the pressure monitoring device is equipped with a communication module compatible with the first communication module;

[0033] The cache module is used to back up and store the pressure data;

[0034] The intelligent controller is used to control the second communication module to transmit the pressure data to the background server to realize automatic recording of the data.

[0035] In this embodiment, the background server has the same meaning as the cloud server in the accompanying drawings, and users can remotely view real-time pressure data through mobile phones, computers and other devices; it should be noted that this embodiment uses pressure data as an example for illustration, and may also include the transmission of other sensor data, such as temperature data, which will not be elaborated here.

[0036] When in use, the intelligent controller also includes a power supply port for connecting to a power adapter, so that the system has two power supply modes; one is powered by a rechargeable lithium battery. The rechargeable lithium battery (i.e., the industrial-grade power bank in the attached figure, which is resistant to low temperatures) can continuously power the intelligent controller for more than 12 hours at a time (generally, a pressure holding test is about 3-6 hours), and the rechargeable lithium battery can operate in an environment of minus 40 degrees Celsius;

[0037] Alternatively, if there is AC power on site, the intelligent controller can also be powered by AC power through a power adapter; these two power supply methods provide users with flexible choices.

[0038] In this embodiment, the first communication module is illustrated by taking a Bluetooth module and the second communication module is illustrated by taking a 5G module as an example; further, the pressure detection system also includes the pressure monitoring device, and the pressure monitoring device also includes a memory module for recording the pressure data in real time.

[0039] Specifically, the pressure monitoring device uses a digital pressure gauge (i.e., the smart pressure gauge in the attached figure), which is installed in the pressure pipe to collect pressure data, and its measurement range is 0-420MPa; the first communication module is used for Bluetooth communication between the digital pressure gauge and the smart controller; the second communication module is used for the smart controller to remotely transmit 5G signals to the background server.

[0040] When in use, the pressure detection system also includes a tool box for accommodating the power module, intelligent controller and pressure monitoring device, and the tool box is matched with a placement structure that is compatible with the power module, intelligent controller and pressure monitoring device.

[0041] The toolbox is made of aluminum alloy and is configured with various specifications for connecting the power module and the charging cable of the intelligent controller, thereby achieving convenient and fast deployment operations.

[0042] In this embodiment, the intelligent controller is also used to: perform faster data acquisition based on a preset acquisition frequency; make the signal acquisition frequency very high, up to 10 times per second, and can be flexibly set according to actual needs, without any restriction here; while the general 4g pressure gauge collects data about once every 15 minutes or 5 minutes.

[0043] In another embodiment, the intelligent controller can flexibly adjust not only the pressure data acquisition frequency but also the communication frequency to achieve better recording of pressure changes over time.

[0044] The intelligent controller includes a deployed Raspberry Pi, which can analyze and process data on site, and is also equipped with an expansion port, a 32G memory card and a 5G communication card, etc., and is equipped with a Bluetooth antenna and a 5G antenna on the outside to amplify the signal.

[0045] Furthermore, the intelligent controller is also used for:

[0046] When the interference signal disappears, actively controlling the wireless communication module to connect with the pressure monitoring device and / or the backend server;

[0047] Actively identify the breakpoint time point, continue to upload the unuploaded pressure data to the background server and / or read the data within the breakpoint time period from the pressure monitoring device to ensure the continuity of pressure data.

[0048] Specifically, once the wireless communication on site is interfered with, affecting the Bluetooth communication, the Bluetooth is interrupted, that is, the digital pressure gauge cannot communicate with the intelligent controller. At this time, the digital pressure gauge has a memory module, which can record the pressure data in the memory module of the digital pressure gauge. Once the interference signal disappears, the intelligent controller will actively connect to the digital pressure gauge again. After the connection is established, the intelligent controller will identify the breakpoint time point and then read the data within the breakpoint time period from the digital pressure gauge to ensure the continuity of the pressure data.

[0049] Once the 5G communication on site is interfered with, affecting the 5G communication and causing 5G interruption, that is, the intelligent controller cannot communicate with the background server, the intelligent controller has the cache module, which can record the pressure data in the cache module of the intelligent controller. Once the interference signal disappears, the intelligent controller will actively identify the breakpoint time point and continue to upload the unuploaded pressure data to the background server;

[0050] Therefore, double backup and data caching are used to cope with signal interference and ensure that pressure data is not lost during the entire process.

[0051] Furthermore, based on the above technical solution, the pressure detection system also includes a data receiver for realizing long-distance data reception; for example, a LORA data receiver, which is mainly used to collect and process wireless data from LoRa devices in the Internet of Things (IoT) and is a low-power long-range wireless communication technology; it has the characteristics of long-distance transmission, low power consumption, strong anti-interference ability and easy deployment.

[0052] In this embodiment, a pressure detection system that can be used for outdoor wireless data transmission is proposed, which can realize the collection, transmission, storage and traceability of pressure data anytime and anywhere in harsh industrial environments without the need to deploy an external power supply and network; thereby making the pressure holding test safer, more convenient and more efficient; at the same time, through double backup and data caching, it is ensured that the pressure data is not lost during the entire process, so that the validity of the data is guaranteed, overcoming the signal attenuation or loss problem existing in the existing technology.

[0053] Furthermore, the backend server is also used to automatically generate pressure curves in real time and retain historical pressure holding test data, so that users can retrieve historical data at any time to facilitate data analysis and traceability;

[0054] At the same time, the backend server is preset with a pressure test report template, which can directly generate a report that meets user requirements with one click; the pressure test report template can be selected based on user needs, or the template can be edited and used.

[0055] When applied, the background server can also manage all smart pressure gauges through the adapted application program, making the work more efficient;

[0056] And tool certificate information and early warning management; that is, all smart pressure gauges used by the user can be entered, and the corresponding calibration certificate information can be entered, so that early warning and certificate expiration alarm can be issued according to the certificate validity period;

[0057] At the same time, various alarm functions can be flexibly set, including:

[0058] 1. Working pressure threshold alarm

[0059] After the pressure holding stage is started, the upper and lower pressure limits can be set during this stage. If the pressure is outside the upper and lower limits, an automatic alarm will be triggered.

[0060] 2. Certificate validity period warning

[0061] The certificate expiration time can be customized, for example, 1 month, which triggers an early warning to remind users to renew the certificate in advance;

[0062] 3. Certificate expiration alarm

[0063] When a certificate expires (personnel qualification certificate, tool calibration certificate, etc.), an alarm will be triggered if the validity period has expired.

[0064] 4. Working hours alarm

[0065] The pressure holding time of the pressure holding test can be set in advance. Once the pressure holding time is exceeded, an alarm will be triggered to remind you that the pressure holding test is over.

[0066] This allows for more alarm content to be flexibly configured based on user needs.

[0067] In the embodiments provided in this application, it should be understood that the disclosed system can also be implemented in other ways. The embodiments described above are merely illustrative. It should also be noted that in some alternative implementations, the functions marked in the blocks can also occur in an order different from that marked in the accompanying drawings.
