Description

Technical Field

[0002] Existing telemetry terminal machines integrate various communication technologies and can comprehensively implement a series of comprehensive operations such as water resource data collection, storage, display, control, alarm, and transmission, playing an important role in data monitoring and management in industries such as water conservancy.

[0003] In the prior art, the acquisition frequency of the telemetry terminal machine in the water pressure signal detection link is insufficient. Facing frequent fluctuations in water pressure, it is difficult to capture abnormal change data, resulting in the loss of key information and unable to provide complete and accurate original data for subsequent data analysis; when in an environment with poor signal strength, the positioning of the telemetry terminal machine is prone to deviation or signal loss, affecting the position accuracy of data collection.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0039] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0041] A 5G telemetry terminal, as Figure 1 shown, includes

[0042] A signal acquisition module 1 that acquires the pressure data of an external sensor through a first acquisition frequency;

[0043] A main control chip 2, connected to the signal acquisition module 1, for receiving and processing the pressure data to obtain processed data;

[0044] A 5G signal module 3, connected to the main control chip 2, for transmitting the processed data to a server platform;

[0045] A storage module 4, connected to the main control chip 2, for storing the processed data according to the instructions of the main control chip 2;

[0046] A multi-system combined satellite navigation positioning and timing module 5, connected to the main control chip 2, for providing position information and time information during pressure data acquisition, and simultaneously synchronizing the time pulse signal of the main control chip (2) according to Coordinated Universal Time.

[0047] Specifically, the present invention provides a 5G telemetry terminal. Through the high-frequency acquisition method of the signal acquisition module 1, fluctuating data can be effectively acquired, and the obtained analog signal is converted into a digital signal, making the data reported to the main control chip 2 more complete. By providing position information and time information during pressure data acquisition through the multi-system combined satellite navigation positioning and timing module 5, the time accuracy and position accuracy of data acquisition are relatively high.

[0048] In a preferred embodiment, the signal acquisition module 1 includes

[0049] A 5V voltage output port for supplying power to an external sensor;

[0050] A voltage signal input port for receiving the analog signal quantity uploaded by an external sensor;

[0051] A ground interface.

[0052] Specifically, the signal acquisition module 1 is a port for acquiring high-frequency pressure data, which is arranged outside the 5G telemetry terminal and consists of three interfaces, namely a 5V voltage output port, a voltage signal input port of 0 - 5V, and a ground interface.

[0053] For sensors that can meet the acquisition frequency voltage, they can be directly connected to the voltage signal line and the ground line to upload analog signal quantities.

[0054] For sensors that require 5V power supply, they only need to connect the power line to the 5V interface to achieve power supply.

[0055] The device is also provided with a 12V voltage power supply as an additional power supply option. After collecting the data of the sensors, it will be packed and sent to the cloud platform through the 5G signal module 3 for data analysis.

[0056] In a preferred embodiment, the storage module 4 includes,

[0057] A memory card, which is soldered to the circuit board by surface mount.

[0058] Specifically, in order to minimize the maintenance cost of the storage module 4 during daily use, all external accessories (such as user identification cards and memory cards) are soldered to the circuit board by surface mount, which not only ensures the stability of their connection but also avoids unnecessary damage caused by later replacement.

[0059] Surface mount soldering makes the card form a firm physical connection with the circuit board, and the solder joints can ensure the stability of signal transmission, reduce data transmission interruption or errors caused by loose connection, ensure the normal operation of the device in various complex environments, and maintain the stable reading and writing of data.

[0060] After adopting surface mount soldering, there is no need to perform replacement operations caused by damaged connection components, which reduces the maintenance frequency and cost of the device, and also reduces the device downtime caused by maintenance, improving the overall availability and operation efficiency of the device.

[0061] When a situation of data transmission failure occurs due to communication failure, the main control chip 2 sends an instruction to temporarily store the failed data in the memory card and upload it again after the communication is restored.

[0062] In a preferred embodiment, a data erasure control unit is provided in the main control chip 2, which is used to detect the data volume in the memory card. When the data volume in the memory card exceeds the set threshold, the data that has been sent in the memory card is erased.

[0063] Specifically, the memory card is configured with an erasure function, which eliminates the need for maintenance personnel to regularly replace and delete data in traditional memory cards.

[0064] When data is continuously written into the memory card, the data erasure control unit of the main control chip 2 will monitor the data volume in the memory card in real time or at preset intervals (the preset time can be every hour, every day or every week).

[0065] The stored data volume is tracked through a built-in counting mechanism or storage management algorithm. Once it is detected that the data volume reaches a pre-set threshold, the data erasure control unit of the main control chip 2 will initiate an erasure program.

[0066] The built-in counting mechanism is based on the byte counting principle, accumulating and counting each data byte written to the memory card. When the accumulated value reaches the number of bytes corresponding to the set threshold, the erasure program is triggered.

[0067] For example, if the storage upper limit of the memory card is set to 1GB (1073741824 bytes), the counting mechanism continuously accumulates newly written data bytes. Once the sum reaches this value, subsequent operations are initiated.

[0068] The storage management algorithm is an idle space management algorithm based on the file system. It periodically scans the file allocation table (FAT) of the memory card or a similar file system structure, calculates the number of allocated and unallocated storage blocks, and thus determines the remaining available space. When the available space is lower than a preset threshold ratio (such as when the remaining space is less than 10% of the total capacity), the data erasure process is triggered.

[0069] The erasure program follows a specific file deletion logic. It first deletes the earliest stored data, or performs selective deletion based on factors such as the importance level of the data and the storage time, in order to free up storage space and ensure that the memory card can continue to normally store new data.

[0070] When adopting the first-in, first-out file deletion logic, the data erasure control unit of the main control chip 2 accurately locates the earliest stored data file in the memory card and deletes it in chronological order until enough storage space is freed up.

[0071] When performing the erasure operation according to the importance level of the data, the data erasure control unit of the main control chip 2 will pre-classify the data according to the data source, type, or the priority set by the user. When data needs to be deleted, data with a high importance level is preferentially retained, and deletion starts from the data with the lowest importance level.

[0072] It is also possible to consider both the time factor and the importance factor of the data. The data erasure control unit of the main control chip 2 records the storage start time of each data file, and preferentially deletes those data that have been stored for the longest time and are relatively unimportant, so as to ensure that the memory card always maintains sufficient available space, thereby ensuring that new data can be smoothly written to the memory card and stored normally, maintaining the efficient operation state of the memory card, and meeting the continuous data storage requirements of the device.

[0073] In a preferred embodiment, refer to Figure 2, the multi-system combined satellite navigation, positioning and timing module 5 includes a global navigation satellite system multi-mode positioning chip U1, and is provided with on the global navigation satellite system multi-mode positioning chip U1,

[0074] A data transmission pin TXD, connected to the main control chip 2;

[0075] A data reception pin RXD, connected to the main control chip 2;

[0076] A pulse signal output pin 1PPS, connected to the main control chip 2;

[0077] A main power supply pin VCC, connected to a 3.3V power supply to supply power to the global navigation satellite system multi-mode positioning chip U1;

[0078] A backup power supply pin V_BCKP, connected to a backup battery, and when the main power supply pin VCC is powered off, it supplies power to the real-time clock of the global navigation satellite system multi-mode positioning chip U1;

[0079] A reset pin NRST, connected to a reset module, used to reset the multi-system combined satellite navigation, positioning and timing module 5;

[0080] An active antenna power supply and detection pin VCC_RF, connected to an active antenna, used to supply power to the active antenna and detect the working state of the active antenna;

[0081] A radio frequency signal input pin RF_IN, connected to the main control chip 2, used to obtain the time signals of the Beidou satellite navigation system and the global positioning system.

[0082] Specifically, a global navigation satellite system multi-mode positioning chip U1 is adopted, namely L76K. Among them, the data transmission pin TXD and the data reception pin RXD are UART interfaces, used for receiving and sending data.

[0083] The main power supply pin VCC and the backup power supply pin V_BCKP are respectively connected to the main power supply and the RTC backup power supply. When the main power supply is disconnected, power is supplied to the RTC (real-time clock) through the backup power supply pin V_BCKP.

[0084] The reset pin NRST is used to reset the module, and is valid at low level. The main function of the radio frequency signal input pin RF_IN is to obtain the time signals from the BDS (Beidou satellite navigation system) and the GPS (global positioning system) and transmit them to the main control chip 2 for encoding and processing.

[0085] The satellite configuration of the global navigation satellite system multi-mode positioning chip U1 is GPS+BeiDou. The GPS and BDS systems send accurate time signals to the global navigation satellite system multi-mode positioning chip U1 through a group of satellites running in the earth's orbit.

[0086] The GPS and Beidou dual-mode clock calibration instrument has strong anti-interference ability and can operate stably under harsh weather conditions. It is small in size and light in weight, can be easily installed in various devices, and has a long service life and low maintenance cost.

[0087] The GPS and Beidou dual-mode clock calibration instrument supports multiple interfaces, including serial ports, network ports, USB, etc., and can perform fast and stable time synchronization with various devices.

[0088] The global navigation satellite system multi-mode positioning chip U1 is also provided with a first ground pin GND1, a second ground pin GND2, and a third ground pin GND3, and the first ground pin GND1, the second ground pin GND2, and the third ground pin GND3 are all grounded.

[0089] In a preferred embodiment, the multi-system combined satellite navigation positioning and timing module 5 further includes

[0090] A positioning unit, connected to the global navigation satellite system multi-mode positioning chip U1. The positioning unit obtains the coordinate data of the 5G telemetry terminal by analyzing the satellite signals received by the Beidou satellite navigation system and the global positioning system, and processes the position information according to the coordinate data;

[0091] A timing unit, connected to the global navigation satellite system multi-mode positioning chip U1. The timing unit calibrates the clock data of the real-time clock according to the time signals of the Beidou satellite navigation system and the global positioning system, and processes the time information according to the clock data.

[0092] Specifically, the positioning unit is connected to the global navigation satellite system multi-mode positioning chip U1 and continuously receives satellite signals from the Beidou satellite navigation system and the global positioning system. The satellite signals contain key data such as the position information, timestamp, and distance to the terminal of the satellite.

[0093] The positioning unit first demodulates and decodes these signals to extract the useful information. Then, using triangulation, based on the distances from multiple satellites to the terminal and the known positions of the satellites, the three-dimensional coordinate data (longitude, latitude, and altitude) of the 5G telemetry terminal is calculated.

[0094] For example, common GPS positioning uses algorithms based on time difference of arrival (TDOA) or angle of arrival (AOA). By measuring the time difference or angle of the satellite signal arriving at the terminal and combining the satellite orbit parameters, the position of the terminal is calculated.

[0095] After obtaining the coordinate data, the positioning unit will convert and format the coordinate data according to the pre-set map coordinate system or the standards of Geographic Information System (GIS), and convert it into location information that can be directly used by the device or application, such as specific addresses, geographical region names, or precise location markings on a specific map, etc.

[0096] The time calibration unit is also connected to the global navigation satellite system multi-mode positioning chip U1 to receive the high-precision time signals sent by the Beidou satellite navigation system and the Global Positioning System. The time signals are based on the high-precision timing standard of atomic clocks and have extremely high accuracy.

[0097] After receiving the time signal, the time calibration unit first performs synchronization and verification processing on the signal to ensure the integrity and accuracy of the signal. Then, by comparing with the real-time clock inside the terminal, it calculates the time deviation value. According to this deviation value, the time calibration unit adopts appropriate calibration algorithms, such as linear compensation algorithm or Kalman filtering algorithm, etc., to adjust the clock data of the real-time clock.

[0098] For example, if the time shown by the time signal is 10 milliseconds faster than the internal clock of the terminal, the time calibration unit will send an instruction to the real-time clock to make it run faster at a certain rate until the two times are the same.

[0099] After the calibration is completed, the time calibration unit will package and output the calibrated time data according to the requirements of the device in a specific time format (such as Coordinated Universal Time or local time format) as the standard time information of the device for other modules to use when performing data acquisition, recording, transmission and other operations, ensuring the accuracy and consistency of the device in terms of time.

[0100] After obtaining coordinate data such as longitude, latitude and altitude, the positioning unit will refer to the geographic information database. This database contains geographic feature information, map grid data, administrative division boundaries, etc. of the whole world or a specific region. The positioning unit determines the geographical location of the terminal by matching and comparing the calculated coordinate data with the data in the geographic information database.

[0101] For example, if the coordinate data falls within the specific longitude and latitude range of a certain city and the altitude information is consistent with the terrain features of the area, the positioning unit can determine that the terminal is located in a specific area of the city. At the same time, the positioning unit can also use the map projection algorithm to convert the three-dimensional coordinate data into a planar coordinate suitable for display on a two-dimensional map, so as to intuitively display the location of the terminal in the map application, and add relevant geographical markings according to needs, such as the names of nearby roads, landmark buildings, etc., to further enrich the content of the location information and make it more practical and readable.

[0102] After calibrating the clock data of the real-time clock, the time calibration unit processes it according to the time display format and time zone information set by the device. If the device needs to display local time, the time calibration unit obtains the time zone setting information of the region where the device is located and converts the calibrated Coordinated Universal Time (UCT) to local time.

[0103] For example, if the device is located in the eighth time zone east, the time calibration unit adds an 8-hour time zone offset to the UCT time to obtain the corresponding Beijing time.

[0104] At the same time, the time calibration unit also formats and outputs the time information according to the application requirements of the device. For example, it generates a time string in the format of "year-month-day-hour:minute:second", or provides timestamp data, so as to accurately identify the time attribute of the data during data recording and transmission, ensure the time synchronization between different devices and the accurate analysis of the time correlation of data, and meet the precise requirements of time information in various application scenarios.

[0105] In a preferred embodiment, the accuracy of the time calibration unit is at the millisecond level, and the first acquisition frequency is 100 Hz.

[0106] Specifically, the acquisition frequency of the pressure data acquisition port is 100 Hz. Through high-frequency acquisition, it can more effectively capture the fluctuations of the data. Even if the change time range is relatively short, it can detect abnormal situations in time and report the data for more professional analysis.

[0107] Since the pressure data changes rapidly, high-frequency acquisition can obtain data samples at shorter time intervals.

[0108] For example, in a water supply network, the water pressure may change instantaneously due to pipeline leaks, rapid opening and closing of valves, etc. The acquisition frequency of 100 Hz can collect 100 data points in 1 second. Compared with low-frequency acquisition, it can capture the details of these instantaneous pressure fluctuations more carefully, so as to detect abnormal pressure change trends in time, provide richer and more accurate raw data for subsequent data analysis, greatly improve the detection ability of potential problems and the analysis accuracy, and help to more accurately judge the operation status of the pipeline network and predict the fault risk, etc.

[0109] In a preferred embodiment, the time signal includes a synchronization pulse signal with an interval of 1 s and the Coordinated Universal Time corresponding to the synchronization pulse signal;

[0110] The error between the pulse front edge of the synchronization pulse signal and the Coordinated Universal Time does not exceed 1 ns.

[0111] Specifically, the RF signal input pin RF_IN obtains time signals from BDS and GPS and transmits them to the main control chip 2 for encoding and processing. Two types of time signals can be extracted and output: one is a synchronous pulse signal 1PPS with an interval of 1 second, and the synchronization error between the pulse front edge and UCT (Coordinated Universal Time) does not exceed 1 ns; the other is the UCT time (year, month, day, hour, minute, second) included in the serial port output information.

[0112] The accuracy of the GPS and Beidou dual-mode clock calibration instrument can reach the millisecond level, which is much higher than that of traditional NTP (Network Time Protocol) servers.

[0113] The global navigation satellite system multi-mode positioning chip U1 uses the serial communication method to send the 1PPS pulse signal to the main control chip 2. Since both devices use the standard UCT clock, the synchronization error between the synchronous pulse signal and the UCT clock does not exceed 1 ns. Therefore, the error between the UCT clock times of each device is extremely small. The data collected by the device in the UCT time coordinate system is packaged and uploaded to the server, and the data of each device at the same moment can be obtained through the decoding of the server.

[0114] In a preferred embodiment, a security protection module 6 is further included, which is connected to the multi-system combined satellite navigation positioning and timing module 5. The security protection module 6 is used to monitor the position information and trigger the self-destruction condition when the position information exceeds the preset positioning range, and erase the programs and all data stored internally. Specifically, the security protection module 6 is used to monitor the position information, configure the regional limit of the gps longitude and latitude through the serial port. After the device obtains the longitude and latitude, it compares with the set regional range. If it exceeds the regional range, it erases the programs and all data stored internally.

[0115] The security protection module 6 establishes a connection with the multi-system combined satellite navigation positioning and timing module 5 to obtain real-time position information.

[0116] During the device startup phase or at a specific configuration moment during operation, the operator sends configuration instructions containing the preset longitude and latitude regional limits to the device through the serial port. The security protection module 6 receives and parses these instructions, and stores the preset regional range information in a specific storage area inside it.

[0117] During the device operation, the security protection module 6 continuously receives the position information update from the multi-system combined satellite navigation positioning and timing module 5. Extracts the longitude and latitude data in the position information and compares it with the pre-stored regional range. When the longitude and latitude data exceeds the preset positioning range, the security protection module 6 immediately triggers the data deletion program.

[0118] The data deletion program sends a deletion instruction to the storage module 4. After receiving the instruction, the storage module 4 activates the internal data erasure mechanism and deletes all the processed data and related programs stored in a predetermined order and manner.

[0119] For example, first delete the data in the temporary storage area, and then gradually delete the programs of the main control chip 2 to ensure that the data and firmware are completely erased, prevent the leakage of sensitive information, and thus achieve the security protection of the device data.

[0120] In a preferred embodiment, it further includes an aluminum alloy shell, and inside the aluminum alloy shell, there are a signal acquisition module 1, a main control chip 2, a 5G signal module 3, a storage module 4, a multi-system combined satellite navigation positioning and timing module 5, and a security protection module 6;

[0121] The surface of the aluminum alloy shell is provided with an aluminum oxide protective film formed by sandblasting and oxidation treatment.

[0122] Specifically, the 5G telemetry terminal is applicable to water conservancy or gas pipe networks with high time accuracy requirements and large data volumes.

[0123] The positioning module of the present invention adopts a GPS + Beidou dual-module, which can realize signal mutual switching. Accurate positioning can still be carried out in places where the signal strength is not particularly good. At the same time, it also has a precise self-timing function. The RTU device clock is kept synchronized with the Beidou or GPS clock, and when it can self-calibrate the time, the error accuracy between its system clock and the Beidou or GPS clock is ≤10ms, which greatly improves the data correlation between each device.

[0124] The shell uses aluminum alloy material and is treated with sandblasting and oxidation on the surface. It has a strong adaptability to various harsh environmental conditions, and its firmness and corrosion resistance are also guaranteed.

[0125] The present invention is attached with a remote upgrade function, including remote upgrade, parameter modification, device restart, entering the low-power mode (the device is in the standby state, silently waiting to be remotely awakened by the upper computer and then restarting to work). When the device gets stuck, or the device operation parameters need to be adjusted, or the system firmware needs to be updated uniformly, it can be conveniently operated only through the upper computer.

[0126] Apply the 5G telemetry terminal of the present invention to a certain water service intelligent pipe network system, place the device near each fire water pipe, connect the device and the water pipe valve through a pressure sensor, and obtain the collected data by this device.

[0127] For this device, since its power supply supports wide-voltage input DC5V - 35V and the standard power supply is DC12V, only a battery of about 12V and a solar panel that can continuously charge the battery need to be equipped to ensure the operation of the device.

[0128] After the 5G telemetry terminal is connected to 4 5G signal lines and 1 GPS signal line, the device will automatically obtain coordinates and calibrate the time. It adopts a hybrid positioning technology of GPS and Beidou-2, which can quickly capture and track satellite signals in an environment with weak signals, improving the accuracy and reliability of positioning.

[0129] After the 5G telemetry terminal passes the server verification, it will start to supply power to the sensors (providing 1 12V and 2 5V power supplies). After receiving the voltage signals fed back by the sensors, the device will collect, package the data at a sampling frequency of 100Hz and upload it to the server platform for data analysis.

[0130] When the sim card signal is disconnected, the device will save the collected data in the sd card of the device until the sim card reconnects to the signal, and then it will upload the un-uploaded data again. If it is found that it has been in a signal-free state, the server will receive an alarm and the corresponding maintenance personnel will go to the site to repair it.

[0131] The main control chip 2 of the present invention will perform data format verification on the received pressure data to ensure the integrity and accuracy of the data. According to the pre-set communication protocol and data format specifications, it checks information such as the data packet header and check bits. If data errors or incompleteness are found, it requests the signal acquisition module 1 to re-send the data.

[0132] Next, data filtering processing is performed. Since the data collected by the sensor is affected by factors such as environmental noise, the main control chip 2 uses digital filtering algorithms, such as moving average filtering, Kalman filtering, etc., to remove high-frequency noise and abnormal fluctuations, making the pressure data smoother and more stable for subsequent analysis.

[0133] Then, data conversion and normalization operations are performed. According to the characteristics of the sensor and application requirements, the collected original pressure data is converted into the actual pressure value and normalized to a specific numerical range. For example, the pressure value corresponding to the voltage signal of 0 - 5V is converted into the standard pressure value in pascal (Pa) and mapped to a numerical interval such as 0 - 100 for easy calculation and comparison.

[0134] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
