Description

Technical Field

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

[0002] With the increasing global demand for ocean observations, profile buoys, as an important ocean observation tool, have been widely used. Since the implementation of the international Argo program in 2000, member states have deployed more than 18,000 profile buoys globally, collecting millions of upper ocean temperature and salinity profile data, providing a large amount of basic data for global climate research and marine science. Profile buoys continuously collect ocean profile data and sensor monitoring information and transmit the data to the shore-based command and control center, providing important support for ocean environmental monitoring, climate change research, etc.

[0003] Among the various components of a profile buoy, the main board is one of its core components and undertakes crucial functions. The main board is mainly used to receive and parse the control parameters issued by the shore-based command and control center, control the working modes of the buoy and its sensors according to these control parameter instructions, and perform data acquisition and profiling operations. When the buoy obtains relevant temperature and salinity profile data, sensor monitoring information, and buoy status information, the main board transmits this data back to the shore-based command and control center through the communication module. The functions and stability of the main board directly determine the overall working performance of the profile buoy and the accuracy of the data.

[0004] During the production process of profile buoys, the functions and stability of the main board need to be fully tested in multiple stages such as after the main board is processed, high and low temperature tests of the main board and the whole machine, and vibration tests of the main board and the whole machine. Currently, in the process of main board testing, manual testing methods are mainly relied on, and there are many problems with this traditional method. In terms of voltage and current monitoring, testers manually judge the voltage and current of the main board, each sensor, and the external device ports through the power supply and an external multimeter, which is prone to introducing human errors and has low testing efficiency. In terms of the function testing of the main board, the output of the sensors is mainly tested according to the profile working process of the buoy. During the testing process, the main board receives and parses the manually input parameters through the serial port to obtain the current working mode and working parameters, controls the sensors to work, saves the serial port output log information after the testing, and manually analyzes it to judge whether the functions of the hardware circuit, pins, and sensors are normal. The testing efficiency is low. In addition, after a long time of testing, due to the large amount of serial port log data and no fixed output format, it is difficult to analyze the data, and it is easy to miss or make mistakes in the analysis.

[0005] In the traditional manual testing method, the average time for main board function testing is about 0.5 hours, while the time for stability testing is as high as 4.5 hours. Especially during the mass production process of profile buoys, the testing efficiency is low, seriously restricting the production progress. Moreover, due to the large dependence on manual operations during the testing process, the accuracy and stability of the test results are also affected to a certain extent. Therefore, there is an urgent need to develop a new system and method for main board stability testing to improve testing efficiency, reduce human errors, and enhance the overall quality and reliability of products. Summary of the Invention

[0006] In view of the deficiencies existing in the above-mentioned prior art, the present invention provides a method and system for main board stability testing of profile buoys to solve problems such as low efficiency, difficult data analysis, influence by manual operations, and high professional technical requirements for testers in manual testing.

[0007] On the one hand, the present invention provides a method for main board stability testing of profile buoys. The main board to be tested is externally connected with multiple sensors. The testing method includes the following steps: Establishing a connection: Establishing a connection between the upper computer testing system and the main board to be tested; Stage testing: The upper computer testing system issues control instructions to the main board to be tested according to the test parameters in the configuration file. After receiving and parsing the test parameters, the main board to be tested enters the stage testing process. The stage testing process includes functional testing of the main board to be tested in different working stages according to the working process of the profile buoy, and independent stage testing in different working stages; Data acquisition and processing: The voltage acquisition module and current acquisition module on the test tooling acquire the voltage values and current values of each port and sensor of the main board to be tested during functional testing and independent stage testing. The upper computer testing system reads the voltage values, current values, and information returned by the serial port server of the test tooling in real time for analysis and processing; Test result display: The upper computer testing system displays in real time the test stage where the main board to be tested is located and whether there is abnormal information, and locates the position where the abnormal information exists.

[0013] In some embodiments of the present application, the test contents of the ascent stage are the same as those of the hovering stage. During the hovering stage, the host computer test system sends random numbers with random lengths of bytes according to the serial port information of each sensor in the configuration file; After receiving the above random numbers, the main board to be tested 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 read and write of the main board to be tested, and the function of the memory card are normal by comparing whether the received and sent random numbers are exactly the same.

[0014] In some embodiments of the present application, during the hovering stage, the host computer test system also monitors the current and voltage changes of the pump control module and the relevant circuits of the solenoid valve to determine whether the pump control module and the solenoid valve are abnormal.

[0015] In some embodiments of the present application, during the stage test, after the previous stage test is completed, the host computer test system receives the information indicating the end of the test. When the information shows that the main board to be tested is in a normal state, the main board to be tested continues the next test process. When the information shows that there is abnormal information on the main board to be tested, the test of the main board to be tested is stopped.

[0016] In some embodiments of the present application, when the host computer test system is connected to the main board to be tested, the main board to be tested is first connected to the test fixture, the test fixture 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 main board to be tested and the threshold values of the measured parameters; the test fixture is powered on, and the host computer test system powers on each module of the main board to be tested included in the configuration file through the test fixture, resets the Bluetooth module on the test fixture, and establishes a communication connection between the host computer test system and the main board.

[0017] On the other hand, the present invention also provides a stability test system for a profiling buoy main board, including a host computer test system and at least one test fixture.

[0023] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0024] This embodiment discloses a method for testing the stability of a profile buoy main board. The main board to be tested is externally connected with multiple sensors. The main board to be tested communicates and transmits data with the upper computer test system through a serial server and a switch on the test fixture in sequence. The upper computer test system includes an information monitoring module, a data analysis module, and a data visualization module. The functions and stability of the main board are tested by monitoring the current and voltage of the main board, each sensor, and the externally connected sensors. In order to facilitate the monitoring of the current and voltage, a voltage acquisition module and a current acquisition module are set in the main control circuit of the test fixture. The voltage acquisition module acquires the voltage values of each port of the main board to be tested and the externally connected sensors, and the current acquisition module acquires the current values of each port of the main board to be tested and the externally connected sensors. The upper computer test system compares with the thresholds of each voltage and current in the configuration file, so as to realize the monitoring of the voltage and current.

[0025] When conducting functional and stability tests on the main board to be tested, a test process is formulated according to the working process of the profile buoy. During the test, the information monitoring module of the upper computer test system monitors the status information and perception information of each sensor returned by the serial server in real time. The data analysis module conducts real-time analysis and monitors the functions of the main board and sensors in real time in combination with the configuration information of each monitoring information. The abnormal information is displayed through the data visualization module.

[0026] During the test, with the support of the upper computer performance and hardware ports, the switch can be connected to multiple test fixtures simultaneously, enabling the upper computer test system to test multiple main boards at the same time to improve the test efficiency.

[0027] As Figure 1 - Figure 2 shown, the test method includes the following steps: Establish a connection between the upper computer test system and the main board to be tested. First, the main board to be tested is connected to the test fixture, the serial server on the test fixture is connected to the switch, the switch can be connected to the serial servers of multiple test fixtures simultaneously, and the serial server is connected to the upper computer test system.

[0028] Then start the upper computer test system, parse the configuration file, and obtain the configuration information of the main board to be tested and the threshold values of the measured parameters. The main board configuration information includes the unique identification code of the main board, the serial port number of the external sensor, the serial port number of the Bluetooth debugging, the serial port number of the serial server, and the communication device (Iridium, Beidou) number; the measured parameters include two categories: the software and hardware information of the main board and the threshold information, specifically including the software and hardware version numbers, the software compilation time, the voltage and current threshold values when each sensor works, and the sensor measurement threshold values.

[0029] Power on the test fixture. The upper computer test system powers on each module of the main board to be tested included in the configuration file in sequence through the relay of the test fixture, resets and pairs the Bluetooth module on the test fixture, and establishes a communication connection between the upper computer test system and the main board to be tested. At this time, the main board to be tested enters the waiting test mode, sends status information to the upper computer test system, and waits for the upper computer test system to issue a test instruction.

[0030] The whole process of the actual profile observation of the profile buoy is divided into four stages, as Figure 3 shown. The upper computer test system generates control instructions according to the test parameters configured by the user and issues them to the main board to be tested. The main board to be tested receives and parses the parameters and enters the stage test process, and the actual test stage is specified by the user configuration.

[0031] According to the test requirements, there are two types of test parameters configured by the user. One is sequential testing, that is, sequential testing of each working stage according to the working process of the profile buoy, which is mainly used for the function testing of the main board to be tested; the other is independent stage testing. Independent stage testing includes surface drifting stage, descent stage, hovering stage, and ascent stage testing. It can independently test one of the specified stages or repeat the testing of each stage multiple times to obtain the values of the pressure sensor, which is mainly used for the pressure testing of the main board to be tested. After the independent stage testing is completed, an information indicating the end of the stage testing is sent to the host computer test system, and it enters the test mode to wait for the issuance of new test parameters.

[0032] Specifically, in the function testing stage, the host computer test system monitors whether the initialization information and basic modules of the main board to be tested are normal; the initialization information includes software and hardware information, profile buoy preset parameters, and status information; the basic modules include GPS module, Iridium module, pump control module, solenoid valve, pressure sensor, CTD, and memory card. The current and voltage values of the pump control module and the solenoid valve are detected to determine whether they are normal.

[0033] In the surface drifting stage, the profile buoy main board reads the analog data of the CTD, pressure sensor, and wire-pulling sensor in the memory card file, and sends the observation data, GPS information, system time, and buoy status information to the shore base through the Iridium communication module. In the test process of the surface drifting stage, the host computer test software system monitors the status of the main board to be tested and sends random numbers with variable lengths to simulate the read and write operations of the observation data according to the current status; it analyzes the temperature, humidity, air pressure, Iridium, and GPS module information to determine whether the information meets the set threshold range.

[0034] In the descent stage, the profile buoy main board opens the solenoid valve to return oil, and the volume of the oil bladder decreases, thereby reducing the buoyancy of the buoy so that it descends to a specified depth at a certain speed. In the test process of the descent stage, the host computer test software system needs to monitor the working status of the solenoid valve and monitor whether the current and voltage values during its working process meet the rated values.

[0035] During the hovering stage, the main board of the profiling buoy mainly conducts profiling observations through the CTD and pressure sensors to obtain the ocean temperature, salinity, and depth data at the hovering depth. In the test process of the hovering stage, the main board to be tested sends information to notify the host computer test software system that it is currently in the hovering stage, and the simulation of sensor data acquisition and data reading and writing can start. The host computer test software system then sends random numbers of random lengths according to the serial port information of each sensor in the configuration file to simulate the writing operation of the observation data. After receiving the random numbers, the main board to be tested writes the data into the memory card and reads it again from the memory card and sends it to the host computer test system through the serial port server. The host computer test system determines whether the functions of the sensor serial port server, the main board reading and writing, and the memory card module are normal by comparing whether the received data is exactly the same as the sent data. At the same time, monitor the working status of the pump control module and the solenoid valve, and monitor the voltage and current changes in the relevant circuits when they are working.

[0036] During the ascending stage, the main board of the profiling buoy controls the oil drainage into the oil bladder through the pump control module. The volume of the oil bladder increases, thereby increasing the buoyancy of the buoy, so that the profiling buoy ascends to the water surface at a certain speed. During the ascending process, profiling observations are carried out to obtain the temperature, salinity, and depth data of different water layers. Therefore, during the ascending stage, the test function of the main board to be tested is the same as that in the hovering stage.

[0037] After the profiling buoy ascends, it will continue the surface drifting stage. The test content at this time is the same as that in the initial surface drifting stage of the profiling buoy. The host computer test software system monitors the status of the main board to be tested and sends random numbers with variable lengths according to the current status to simulate the reading and writing operations of the observation data; analyzes the temperature, humidity, air pressure, Iridium, and GPS module information to determine whether the information meets the set threshold range.

[0038] The voltage acquisition module and current acquisition module on the test fixture collect the voltage values and current values of each port and sensor of the main board to be tested during the functional test and the independent stage test. The host computer test system reads the voltage values, current values, and other information returned by the serial port server of the test fixture in real time for analysis and processing; for the voltage values and current values, the intervals are mainly set based on the rated values and empirical values of each sensor for statistical analysis; for the random numbers with random lengths sent, it is determined whether the file reading and writing function of the main board is normal by comparing whether the sent data is exactly the same as the received data; the temperature, salinity, depth, humidity, pressure, and GPS data are statistically analyzed according to the appropriate threshold intervals set according to the actual test environment. The original data generated during the test process and the results of the data analysis are classified and saved according to the unique identification code of the main board, the test stage it is in, and the type of monitored information.

[0039] The visualization module of the host computer test system displays in real time the test stage, the current status of the main board to be tested, and whether there is abnormal information. The test parameter information set by the user can be located in a timely manner according to the location where the abnormal information exists.

[0040] During the stage test, after the previous stage test is completed, the host computer test system receives the information indicating the end of the test. When the information shows that the main board to be tested is in a normal state, the main board to be tested will continue with the next test process. When the information shows that there is an abnormal message on the main board to be tested, the test of the main board to be tested will be stopped.

[0041] The test method of this embodiment can perform automated testing on the profile buoy main board, conduct different-stage tests on different main boards according to test parameters, be able to monitor and analyze data in real time, obtain abnormal information in a timely manner, greatly reduce the pressure of post-data processing, improve the test efficiency and reduce the influence of human factors on the test results.

[0042] Another embodiment of this application provides a stability test system for a profile buoy main board, including a host computer test system and at least one test fixture. The host computer test system and the test fixture communicate and transfer data through 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, enabling the host computer test system to communicate and transfer data with multiple main boards to be tested simultaneously; The test fixture is also provided with a main control circuit, such as Figure 3 shown. The main control circuit of this embodiment includes a voltage acquisition module, a current acquisition module, four power resistors, two regulated 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 elaborated here.

[0043] 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 for monitoring voltage, current, and the information returned by the serial port server; The data analysis module is used for analyzing and processing the monitoring information of the information monitoring module, and judging the working states of the main board and the external sensor in real time by means of threshold detection and comparison with preset information; the data visualization module is used for receiving input test information and displaying abnormal information so that the test personnel can locate the problem in a timely manner.
