Description

Technical Field

[0001] The present invention relates to the field of profile buoy mainboard testing, and in particular to a method and system for testing the stability of a profile buoy mainboard. Background Art

[0002] With the increasing demand for global ocean observations, profiling floats, as a crucial ocean observation tool, have gained widespread application. Since the launch of the international Argo program in 2000, member countries have deployed over 18,000 profiling floats worldwide, collecting millions of upper ocean temperature and salinity profiles, providing a wealth of fundamental data for global climate research and ocean science. Profiling floats continuously collect ocean profile data and sensor monitoring information, transmitting this data to shore-based command and control centers, providing crucial support for marine environmental monitoring and climate change research.

[0003] Among the various components of a profiling buoy, the mainboard is a core component, fulfilling a crucial role. It receives and interprets control parameters issued by the shore-based command and control center. Based on these control parameters, it controls the operating mode of the buoy and its sensors, enabling data acquisition and profiling. Once the buoy acquires relevant temperature and salinity profile data, sensor monitoring information, and buoy status information, the mainboard transmits this data back to the shore-based command and control center via the communication module. The mainboard's functionality and stability directly determine the overall performance of the profiling buoy and the accuracy of its data.

[0004] During the production process of profiling buoys, the motherboard's functionality and stability require thorough testing at multiple stages, including after the motherboard is fabricated, after the motherboard and the entire unit undergo high and low temperature testing, and after the motherboard and the entire unit undergo vibration testing. Currently, this motherboard testing process primarily relies on manual testing, a traditional approach with numerous problems. For voltage and current monitoring, testers manually interpret the voltage and current on the motherboard, sensors, and external device ports using a power supply and an external multimeter. This is prone to human error and results in low testing efficiency. For motherboard functional testing, sensor outputs are primarily tested based on the buoy profiling workflow. During testing, the motherboard receives and parses manually entered parameters via the serial port to determine the current operating mode and parameters, controlling sensor operation. After the test, the serial port output log is saved and manually analyzed to determine whether the hardware circuitry, pins, and sensors are functioning properly, resulting in low testing efficiency. Furthermore, after extended testing, the large volume of serial port log data and the lack of a fixed output format make data analysis difficult, prone to omissions or errors.

[0005] Traditional manual testing methods take an average of approximately 0.5 hours to complete a motherboard functional test, while stability testing can take as long as 4.5 hours. This low testing efficiency is particularly significant during the mass production of profiling buoys, severely hindering production progress. Furthermore, the testing process's heavy reliance on manual intervention also impacts the accuracy and stability of test results. Therefore, there is an urgent need to develop a new motherboard stability testing system and method to improve testing efficiency, reduce human error, and enhance overall product quality and reliability. Summary of the Invention

[0006] In response to the above-mentioned shortcomings in the existing technology, the present invention provides a method and system for testing the stability of a profile buoy mainboard, so as to solve the problems of low efficiency of manual testing, difficulty in data analysis, influence of human operation, and high professional and technical requirements for testers.

[0007] In one aspect, the present invention provides a method for testing the stability of a profile buoy mainboard, wherein the mainboard to be tested is connected to a plurality of sensors, and the testing method comprises the following steps:

[0008] Establish connection: Establish a connection between the host computer test system and the motherboard to be tested;

[0009] Stage test: The host computer test system issues control instructions to the motherboard under test according to the test parameters in the configuration file. After receiving and parsing the test parameters, the motherboard under test enters the stage test process. The stage test process includes functional testing of the motherboard under test at different working stages according to the workflow of the profiling buoy, and independent stage testing of different working stages;

[0010] Data acquisition and processing: The voltage acquisition module and current acquisition module on the test fixture collect the voltage and current values ​​of each port and sensor of the motherboard under test during the functional test and independent stage test. The host computer test system reads the voltage and current values ​​and the information returned by the serial port server of the test fixture in real time for analysis and processing;

[0011] The test results show that the host computer test system displays in real time the test stage of the motherboard to be tested and whether there is any abnormal information, and locates the location where the abnormal information exists.

[0012] The testing method of this technical solution can perform automated testing on the profile buoy mainboard, conduct different stage tests on different mainboards according to the test parameters, monitor and analyze data in real time, obtain abnormal information in a timely manner, greatly reduce the pressure of data post-processing, improve test efficiency and reduce the impact of human factors on test results.

[0013] In some embodiments of the present application, during the functional testing phase, the host computer testing system further monitors whether the initialization information and basic modules of the motherboard to be tested are normal;

[0014] The initialization information includes software and hardware information, profile buoy preset parameters and status information;

[0015] The basic module includes a GPS module, an Iridium module, a pump control module, a solenoid valve, a pressure sensor, a CTD and a memory card, and detects the current and voltage values ​​of the pump control module and the solenoid valve to determine whether they are normal.

[0016] In some embodiments of the present application, the independent stage test includes surface drift stage, descent stage, hovering stage, and floating stage test, and can independently test one of the specified stages, or perform multiple repeated tests on each stage to obtain the value of the pressure sensor.

[0017] In some embodiments of the present application, during the surface drifting stage, the host computer test system also monitors the status of the mainboard to be tested, and sends random numbers of varying lengths based on the current status to simulate the reading and writing operations of the observation data, parses the temperature, humidity and air pressure, Iridium and GPS module information, and determines whether it meets the set threshold range.

[0018] In some embodiments of the present application, during the descending phase, the host computer test system monitors the working state of the solenoid valve, and monitors whether the current and voltage values ​​of the solenoid valve meet the rated values ​​during the operation of the solenoid valve.

[0019] In some embodiments of the present application, the test contents of the floating stage and the hovering stage are the same. In the hovering stage, the host computer test system sends a random number of random length bytes according to the serial port information of each sensor in the configuration file;

[0020] After receiving the random number, the motherboard under test writes the data into the memory card and reads it again from the memory card and sends it to the host computer test system. The host computer test system determines whether the sensor serial port, the reading and writing of the motherboard under test and the memory card function are normal by comparing whether the received and sent random numbers are completely consistent.

[0021] In some embodiments of the present application, during the hovering phase, the host computer test system also monitors the current and voltage changes of the pump control module and the solenoid valve related paths to determine whether the pump control module and the solenoid valve are abnormal.

[0022] In some embodiments of the present application, during stage testing, after the previous stage test is completed, the host computer test system receives information that the test is completed. When the information shows that the motherboard to be tested is in a normal state, the motherboard to be tested continues to the next test process. When the information shows that the motherboard to be tested has abnormal information, the test of the motherboard to be tested is stopped.

[0023] In some embodiments of the present application, when the host computer test system is connected to the mainboard to be tested, the mainboard to be tested is first connected to the test tooling, the test tooling is connected to the host computer test system, the host computer test system is started and then the configuration file is parsed to obtain the configuration information of the mainboard to be tested and the threshold value of the parameter to be tested; the test tooling is powered on, and the host computer test system powers on each module of the mainboard to be tested contained in the configuration file through the test tooling, resets the Bluetooth module on the test tooling, and establishes a communication connection between the host computer test system and the mainboard.

[0024] On the other hand, the present invention also provides a system for testing the stability of a profile buoy motherboard, comprising a host computer test system and at least one test fixture, wherein the host computer test system and the test fixture communicate and transmit data via a serial port server on the test fixture, wherein:

[0025] The test fixture is also provided with a main control circuit, which includes a voltage acquisition module, a current acquisition module, multiple power resistors, multiple voltage-stabilized power supplies, a Bluetooth module, and multiple relays;

[0026] The host computer test system includes an information monitoring module, a data analysis module and a data visualization module;

[0027] The information monitoring module is used for voltage and current monitoring and monitoring of information returned by the serial port server;

[0028] The data analysis module is used to analyze and process the monitoring information of the information monitoring module, and judge the working status of the mainboard and external sensors in real time by means of threshold detection and preset information comparison;

[0029] The data visualization module is used to receive input test information and display abnormal information so that testers can locate problems in a timely manner.

[0030] Based on the above technical solution, the testing method of the present invention can automatically test the profiling buoy mainboard, perform different stage tests on different mainboards according to the test parameters, monitor and analyze data in real time, obtain abnormal information in a timely manner, greatly reduce the pressure of data post-processing, improve test efficiency and reduce the influence of human factors on test results;

[0031] Under the condition that the host computer test system performance and hardware port support, the host computer test system can connect to multiple test fixtures at the same time to test multiple motherboards simultaneously, thereby improving test efficiency.

[0036] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0038] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] This embodiment discloses a method for testing the stability of a profile buoy mainboard. The mainboard to be tested is connected to multiple sensors. The mainboard to be tested communicates and transmits data with a host computer test system through a serial port server and a switch on a test tool. The host computer test system includes an information monitoring module, a data analysis module, and a data visualization module. The function and stability of the mainboard are tested by monitoring the current and voltage of the mainboard and each sensor, as well as the external sensor. In order to facilitate the monitoring of current and voltage, a voltage acquisition module and a current acquisition module are set in the main control circuit of the test tool. The voltage acquisition module collects the voltage values ​​of each port of the mainboard to be tested and the external sensor, and the current acquisition module collects the current values ​​of each port of the mainboard to be tested and the external sensor. The host computer test system monitors the voltage and current by comparing them with the threshold values ​​of each voltage and current in the configuration file.

[0041] When testing the functionality and stability of the motherboard to be tested, a test process is formulated according to the profile buoy workflow. During the test, the information monitoring module of the host computer test system monitors the status information and perception information of each sensor returned by the serial port server in real time. The data analysis module performs real-time analysis and monitors the motherboard and sensor functions in real time in combination with the configuration information of each monitoring information, and displays abnormal information through the data visualization module.

[0042] During testing, if the host computer performance and hardware port support are met, the switch can be connected to multiple test fixtures at the same time, enabling the host computer test system to test multiple motherboards simultaneously, thereby improving test efficiency.

[0043] like Figure 1-Figure 2 As shown, the test method includes the following steps:

[0044] Establish a connection between the host computer test system and the motherboard to be tested. First, the motherboard to be tested is connected to the test fixture. The serial port server on the test fixture is connected to the switch. The switch can be connected to the serial port servers of multiple test fixtures at the same time. The serial port server is connected to the host computer test system.

[0045] The host computer test system is then launched to parse the configuration file to obtain the motherboard configuration information and the threshold values ​​of the parameters to be tested. The motherboard configuration information includes the motherboard's unique identification code, the external sensor serial port number, the Bluetooth debugging serial port number, the serial port number of the serial server, and the communication device number (Iridium, Beidou). The measured parameters include two categories: motherboard hardware and software information, and threshold information. Specifically, this includes hardware and software version numbers, software compilation time, the operating voltage and current thresholds of each sensor, and sensor measurement thresholds.

[0046] After the test fixture is powered on, the host test system sequentially powers on each module of the motherboard under test specified in the configuration file via the test fixture's relays. The Bluetooth module on the test fixture is then reset and paired, establishing a communication connection between the host test system and the motherboard under test. The motherboard under test then enters standby mode, sending status information to the host test system and awaiting test instructions from the host test system.

[0047] The whole process of actual profile observation by the profile buoy is divided into four stages: Figure 3 The host computer test system generates control instructions based on the test parameters configured by the user and sends them to the motherboard under test. The motherboard under test receives and parses the parameters and enters the stage test process. The actual test stage is specified by the user configuration.

[0048] Based on test requirements, user-configured test parameters are divided into two types: sequential testing, which tests each working phase sequentially according to the profiling buoy workflow. This is primarily used for functional testing of the motherboard under test. The other is independent phase testing, which includes surface drift, descent, hovering, and ascent phases. It can independently test a specific phase or repeatedly test each phase multiple times to obtain pressure sensor values. This is primarily used for stress testing of the motherboard under test. After the independent phase test is completed, a message indicating the end of the phase test is sent to the host test system, and the system enters test mode, awaiting the issuance of new test parameters.

[0049] Specifically, during the functional testing phase, the host computer test system monitors whether the initialization information of the mainboard to be tested and the basic module are normal; the initialization information includes software and hardware information, profile buoy preset parameters and status information; the basic module includes GPS module, Iridium module, pump control module, solenoid valve, pressure sensor, CTD and memory card, and detects the current and voltage values ​​of the pump control module and the solenoid valve to determine whether they are normal.

[0050] During the surface drift phase, the profiling buoy's mainboard reads analog data from the CTD, pressure sensor, and cable sensor stored in a memory card file and transmits observation data, GPS information, system time, and buoy status information to shore via the Iridium communication module. During the surface drift phase, the host computer's test software monitors the status of the mainboard under test and, based on the current state, sends random numbers of varying lengths to simulate reading and writing observation data. It also analyzes temperature, humidity, and air pressure information, as well as Iridium and GPS module information, to determine whether the information meets set thresholds.

[0051] During the descent phase, the profile buoy's mainboard opens the solenoid valve to return oil, reducing the volume of the oil sac and, consequently, the buoy's buoyancy, allowing it to descend at a constant speed to the specified depth. During the descent phase test, the host computer's test software system monitors the solenoid valve's operating status and verifies that its current and voltage values ​​meet rated values.

[0052] During the hovering phase, the profiling buoy's mainboard primarily uses CTD and pressure sensors to perform profiling observations, acquiring ocean temperature, salinity, and depth data at the hovering depth. During the hovering phase test process, the mainboard under test sends a message to the host computer test software system, notifying it that it is currently in the hovering phase and can begin simulating sensor acquisition and reading and writing data. The host computer test software system then sends a random number of random-length bytes based on the serial port information for each sensor in the configuration file, simulating the writing of observation data. After receiving the random number, the mainboard under test writes the data to the memory card, reads it again from the memory card, and sends it to the host computer test system via the serial port server. The host computer test system compares the received and sent data for complete consistency to determine the proper functioning of the sensor serial port server, the mainboard read / write module, and the memory card module. Simultaneously, the operating status of the pump control module and solenoid valve is monitored, monitoring changes in voltage and current in the relevant circuits during operation.

[0053] During the ascent phase, the profiling buoy's mainboard, controlled by the pump control module, discharges oil into the oil bladder, increasing the bladder's volume and, consequently, the buoy's buoyancy, allowing it to ascend to the surface at a constant speed. During the ascent, profile observations are conducted, acquiring temperature, salinity, and depth data for different water layers. Therefore, during the ascent phase, the test functions of the mainboard under test remain the same as during the hovering phase.

[0054] After floating up, the profiling buoy will continue the surface drift stage. The test content at this time is the same as that of the profiling buoy in the initial surface drift stage. The host computer test software system monitors the status of the mainboard to be tested and sends random numbers of varying lengths based on the current status to simulate the reading and writing operations of the observation data; it parses the temperature, humidity, air pressure, Iridium and GPS module information to determine whether the information meets the set threshold range.

[0055] The voltage and current acquisition modules on the test fixture collect the voltage and current values ​​of each port and sensor on the motherboard under test during functional and independent testing. The host computer test system reads the voltage, current, and other information returned by the test fixture's serial port server in real time for analysis and processing. For voltage and current values, intervals are set based on the rated values ​​and empirical values ​​of each sensor for statistical analysis. For random numbers of random length, the motherboard's file read and write functions are checked for complete consistency by comparing the sent and received data. Temperature, salinity, depth, humidity, pressure, and GPS data are statistically analyzed using appropriate thresholds based on the actual test environment. The raw data generated during the test and the results of the data analysis are categorized and stored according to the motherboard's unique identification code, the test phase, and the type of monitored information.

[0056] The visualization module of the host computer test system displays in real time the test stage, current status and whether there is any abnormal information of the motherboard to be tested. The test parameter information set by the user can be located in time according to the location of the abnormal information.

[0057] During the stage test, after the previous stage test is completed, the host computer test system receives the test end information. When the information shows that the motherboard to be tested is in normal status, the motherboard to be tested will continue to the next test process. When the information shows that the motherboard to be tested has abnormal information, the test of the motherboard to be tested will be stopped.

[0058] The test method implemented in this paper can perform automated testing on the profile buoy mainboard, conduct different stage tests on different mainboards according to the test parameters, monitor and analyze data in real time, obtain abnormal information in a timely manner, greatly reduce the pressure of data post-processing, improve test efficiency and reduce the impact of human factors on test results.

[0059] Another embodiment of the present application provides a system for testing the stability of a profiling buoy motherboard, comprising a host computer test system and at least one test fixture. The host computer test system and the test fixture communicate and transmit data via a switch and a serial port server on the test fixture. The switch can be connected to the serial port servers of multiple test fixtures, allowing the host computer test system to communicate and transmit data with multiple motherboards to be tested simultaneously.

[0060] The test fixture is also equipped with a main control circuit, such as Figure 3 As shown, the main control circuit of this embodiment includes a voltage acquisition module, a current acquisition module, four power resistors, two voltage-stabilized power supplies, a Bluetooth module, and two relays; each component is connected through an RS485 or RS232 communication interface, and its specific connection form is a relatively mature technical solution in this field and will not be repeated here.

[0061] The host computer test system of this embodiment includes an information monitoring module, a data analysis module and a data visualization module; the information monitoring module is used to monitor voltage and current and monitor the information returned by the serial port server;

[0062] The data analysis module is used to analyze and process the monitoring information of the information monitoring module, and to judge the working status of the mainboard and external sensors in real time through threshold detection and preset information comparison; the data visualization module is used to receive input test information and display abnormal information so that testers can locate problems in a timely manner.

[0063] Based on the above technical solution, the testing method of the present invention can automatically test the profiling buoy mainboard, perform different stage tests on different mainboards according to the test parameters, monitor and analyze data in real time, obtain abnormal information in a timely manner, greatly reduce the pressure of data post-processing, improve test efficiency and reduce the influence of human factors on test results;

[0064] Under the condition that the host computer test system performance and hardware port support, the host computer test system can connect to multiple test fixtures at the same time to test multiple motherboards simultaneously, thereby improving test efficiency.

[0065] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to preferred embodiments, persons skilled in the art should understand that the specific implementation methods of the present invention may still be modified or some technical features may be replaced by equivalents without departing from the spirit of the technical solutions of the present invention, and all of these should fall within the scope of the technical solutions claimed for protection by the present invention.
