Description

Technical Field

[0001] This application relates to the field of sensor data acquisition unit rudder speed jump fault detection technology, and in particular to a detection device and method for sensor data acquisition unit rudder speed jump fault. Background Technology

[0002] The sensor data acquisition unit is part of the electronic cabin components of a certain type of underwater vehicle. Its main function is to collect and record signals from a sensor component on the servo motor, the rudder position indicator, etc., and to upload the recorded signals to the host control computer (hereinafter referred to as VG5) via an interrupt method. The sensor data acquisition unit connects to VG5 through an EPP interface, receiving parallel steering commands from VG5. The CPLD chip on the sensor data acquisition unit processes the received steering commands and converts them into rudder direction and rudder speed signals, which are then output to the servo motor component. During joint debugging of the entire product, VG5 sends continuous steering signals using EPP. The interface sends commands for controlling the servo motor's direction and speed sequentially through the J2 port of the adapter board and the J2 interface on the sensor data acquisition unit to the CPLD device on the sensor data acquisition unit. After being converted into serial servo speed codes by the CPLD's internal logic, the servo speed signal is output as a single serial signal (SDATA). Synchronized by the serial clock (SCLK), the servo speed data of all three servos is output through pin 39 of the CPLD. After isolation by optocoupler U17, the data is output from terminals 22 and 24 of the J3 interface on the sensor data acquisition unit, used to control the subsequent servo motor drive circuit to move the servo motor components. The principle block diagram is as follows: Figure 1 As shown.

[0003] Currently, when a rudder speed jump occurs in the control rudder drive and servo motor of the sensor data acquisition unit in the underwater vehicle's electronics compartment, the underwater vehicle's owner locates the fault to the sensor data acquisition unit. The sensor data acquisition unit is then removed from the electronics compartment and returned to the manufacturer for troubleshooting and repair. The repair procedure involves disassembling the CPLD device on the sensor data acquisition unit, obtaining a new one, and soldering it back on. After the unit is assembled and tested successfully, it is returned to the underwater vehicle's owner for integrated testing. Because this fault can only be exposed through integrated testing by the chief engineer, the entire troubleshooting process is lengthy, inefficient, and consumes significant manpower, material resources, and financial resources. The back-and-forth product turnover also poses risks to quality and security. Therefore, improving the pass rate of electromagnetic compatibility testing for all sensor data acquisition units after delivery, shortening the production cycle, and reducing production costs have become key considerations in its production. Summary of the Invention

The VG5 mounting position is used to install a VG5, and the sensor data acquisition device mounting position is used to install a sensor data acquisition device.

[0007] The adapter plate is located on the inner wall of the housing. The left frame and the right frame are symmetrically arranged on the inner wall of the housing. A guide rail is formed between the left frame and the right frame. The VG5 mounting position, the sensor data acquisition unit mounting position and the adapter plate are located on the guide rail, and the adapter plate is located on one side of the VG5 mounting position and the sensor data acquisition unit mounting position. The VG5 and the sensor data acquisition unit can slide on the guide rail and can be electrically connected to the adapter plate.

[0008] The adapter board is electrically connected to the DC switching power supply, the computer, the simulated servo motor, and the simulated servo drive, respectively, and the simulated servo drive is electrically connected to the simulated servo motor.

[0009] Furthermore, the adapter board is connected to the computer via a serial cable and a network cable.

[0010] Furthermore, the adapter board is connected to the simulated servo drive and the simulated servo motor via a first adapter cable.

[0011] Furthermore, the DC switching power supply is connected to the sensor data acquisition unit via a second adapter cable.

[0012] Furthermore, the housing includes a detachably connected front control panel with components and a rear control panel with components, forming a placement space between the front control panel with components and the rear control panel with components.

[0013] Furthermore, the left frame, right frame, adapter plate, left support column, right support column, liner plate, VG5, sensor data acquisition unit, and DC switching power supply are all located within the placement space.

[0014] Furthermore, both the left and right support pillars are located within the placement space, and the left and right support pillars are connected between the lower side wall of the rear control panel with the components and the right frame body.

[0015] Secondly, the present invention also provides a method for detecting rudder speed jump faults in a sensor data acquisition unit, comprising:

[0016] The computer controls the VG5 to send rudder direction and rudder speed signals via the adapter board;

[0017] The sensor data acquisition unit receives the rudder direction and rudder speed signals through the adapter board, and sends them to the simulated rudder drive and simulated rudder motor after preprocessing, thereby controlling the activities of the simulated rudder drive and simulated rudder motor. The preprocessing involves converting the rudder direction and rudder speed signals into serial rudder speed codes.

[0018] The sensor data acquisition unit acquires the steering voltage data of the simulated servo motor through an adapter board;

[0019] The sensor data acquisition unit sends the steering voltage data to the computer via an adapter board, and the computer displays the waveform of the steering voltage data.

[0020] If the waveform exhibits a jump fault, the sensor data acquisition unit is disassembled, and the components within the sensor data acquisition unit are checked sequentially.

[0021] In one feasible implementation, the detection process is further defined as follows: if the waveform does not exhibit a transition fault, the detection is terminated.

[0022] The beneficial effects of adopting the technical solution of this application are as follows:

[0023] This invention employs an integrated cabinet design, resulting in a compact, safe, and reliable structure. It simulates the electronic cabin environment of an underwater vehicle through a housing and its encapsulated left and right frames, adapter board, VG5 mounting position, sensor data acquisition unit mounting position, and DC switching power supply. It connects to simulated rudder drives and servo motors for fault detection of the sensor data acquisition unit. Specifically: the computer controls the VG5 to send rudder direction and speed signals via the adapter board; the sensor data acquisition unit receives these signals via the adapter board, pre-processes them, and sends them to the simulated rudder drive and servo motors via the adapter board, controlling their movement.

This proactive troubleshooting improves reliability, safety, and accuracy, enabling multi-component signal interaction and other functional integration testing, as well as component compatibility checks. Furthermore, this invention simplifies all component testing processes, reduces product return rates, shortens production cycles, and improves testing efficiency. Attached Figure Description

Detailed Implementation

[0032] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0033] Firstly, such as Figures 2 to 4 As shown, the present invention provides a sensor data acquisition device for detecting rudder speed jump faults, including a computer, a simulated servo motor, a simulated rudder drive, a housing, and a left frame 6, a right frame 4, an adapter plate 5, a liner plate 8, a VG5 mounting position, a sensor data acquisition device mounting position, and a DC switching power supply 11 encapsulated within the housing. The VG5 mounting position 13 is used to install a VG5, the sensor data acquisition device mounting position 12 is used to install a sensor data acquisition device, and the adapter plate 5 is used to connect the VG5 and the sensor data acquisition device.

[0034] The adapter plate 5 is located on the inner wall of the housing. The left frame body 6 and the right frame body 4 are symmetrically arranged on the inner wall of the housing. A guide rail is formed between the left frame body 6 and the right frame body 4. The VG5 mounting position 13, the sensor data acquisition unit mounting position 12 and the adapter plate 5 are located on the guide rail, and the adapter plate 5 is located on one side of the VG5 mounting position 13 and the sensor data acquisition unit mounting position 12. The VG5 and the sensor data acquisition unit can slide on the guide rail and can be electrically connected to the adapter plate 5 on the guide rail.

[0035] The 220V AC power supply is connected to the DC switching power supply. The adapter board is electrically connected to the DC switching power supply, the computer, the simulated servo motor, and the simulated servo drive, respectively. The simulated servo drive is electrically connected to the simulated servo motor.

[0036] The adapter board 5 is connected to the DC switching power supply 11, and the adapter board 5 can provide power and transfer signals to VG5 and the sensor data acquisition unit.

[0037] Furthermore, the adapter board is connected to the computer via a serial cable and a network cable, so that the computer can send and receive data through the adapter board.

[0038] Furthermore, the adapter board is connected to the simulated rudder drive and simulated servo motor via a first adapter cable 3; the DC switching power supply is connected to the sensor data acquisition unit via a second adapter cable 7. The adapter board is connected to the simulated rudder drive and simulated servo motor via the first adapter cable 3 to send serial rudder speed code data to the rudder drive and to receive rudder engagement voltage data from the servo motor. It should be noted that the DC switching power supply is separately connected to the sensor data acquisition unit via the second adapter cable 7, which can be used to provide +28V and +40V power to the sensor data acquisition unit independently.

[0039] In one feasible embodiment, the housing includes a detachably connected front control panel 1 with components and a rear control panel 2 with components, forming a placement space between the front control panel 1 with components and the rear control panel 2 with components; the left frame 6, the right frame 4, the adapter plate 5, the left support column 10, the right support column 9, the liner plate 8, the VG5, the sensor data acquisition unit, the sensor data acquisition unit mounting position 12, and the VG5 mounting position 13, and the DC switching power supply 11 are all located within the placement space.

[0040] The liner has two plates, which are respectively disposed on one side of the left support column 10 and the right support column 9, and provide support and stability for the left support column 10 and the right support column 9.

[0041] Furthermore, both the left support column 10 and the right support column 9 are located within the placement space, and are connected between the side wall of the rear control panel 2 with components and the right frame 4. The left support column 10 and the right support column 9 support the entire assembly of the left frame 6, the right frame 4, the adapter plate 5, the liner plate 8, the VG5 mounting position 13, and the sensor data acquisition unit mounting position 12.

[0042] Secondly, the present invention also provides a method for detecting rudder speed jump faults in a sensor data acquisition unit, comprising:

[0043] Connect the DC switching power supply 11 to a 220V AC power supply and use a multimeter to externally test the +5V, +12V, -12V, and +40V power supplies of the DC switching power supply to check whether the power supply output is normal.

[0044] The computer controls the VG5 to send rudder direction and rudder speed signals via the adapter board;

[0045] The sensor data acquisition unit receives the rudder direction and rudder speed signals through the adapter board, and sends them to the simulated rudder drive and simulated rudder motor after preprocessing, thereby controlling the activities of the simulated rudder drive and simulated rudder motor. The preprocessing involves converting the rudder direction and rudder speed signals into serial rudder speed codes.

[0046] The sensor data acquisition unit acquires the steering voltage data of the simulated servo motor through an adapter board;

[0047] The sensor data acquisition unit sends the steering voltage data to the computer via an adapter board, and the computer displays the waveform of the steering voltage data.

[0048] If the waveform exhibits a jump fault, the sensor data acquisition unit is disassembled, and the components within the sensor data acquisition unit are checked sequentially.

[0049] After the test is completed, shut down the running computer, disconnect the DC switching power supply 11, and turn off the computer power.

[0050] Disconnect the VG5 adapter, sensor data acquisition unit, adapter board 5 from the computer, as well as the sensor data acquisition unit, VG5 from the analog servo motor and analog servo drive, and remove the sensor data acquisition unit assembly and VG5.

[0051] The present invention includes a computer, VG5, a sensor data acquisition unit, an adapter board 5, a first adapter cable 3, a second adapter cable 7, a simulated servo motor, a simulated servo drive, etc., and uses a computer (ordinary desktop computer) to connect to the adapter board via a serial port and a network cable to send and receive signals, and to debug the signal communication between the adapter board 5 and the computer.

[0052] This invention proposes a device and method for detecting rudder speed jump faults in sensor data acquisition units. The detection method combines automated and partially manual detection, integrates hardware and software functions, and uses a multi-board connection via an adapter board 5 to achieve the detection and functional integration of all technical indicators. The invention also studies the working environment of the electronic cabin, constructs an electronic cabin test bench simulating the operation of the sensor data acquisition unit components, simulates the steering mode of full product integration, collects the output signals of the sensor data acquisition unit, and performs data analysis. For products exhibiting rudder speed data jumps, the problem is eliminated by replacing relevant components, thereby removing rudder speed jump faults caused by sensor data acquisition units during full product integration.

[0053] The sensor data acquisition unit for detecting rudder speed jump faults mainly consists of a front control panel 1 with components, a rear control panel 2 with components, a DC switching power supply 11, an adapter board 5, a first adapter cable 3, a second adapter cable 7, a left frame 6, a right frame 4, a left support column 10, a right support column 9, a liner plate 8, a VG 5, a computer, a simulated servo motor, and a simulated rudder drive. A connection diagram of each part is shown below. Figure 2 As shown.

[0054] The hardware design of this invention adopts the concept of whole machine design, which reduces the need for external equipment while ensuring that the testing requirements are met. All component testing can be completed with only a 220V power supply.

[0055] This invention can display the rudder speed settings and forward / reverse direction settings for the three rudders (upper straight rudder, side rudder, and lower straight rudder) on a computer based on the rudder control status. There are a total of 10 setting items (two for upper straight rudder forward / reverse, one for side rudder forward / reverse, and two for lower straight rudder forward / reverse). The actual situation of the rudder voltage collection interface is as follows: Figure 5 As shown.

[0056] The mechanical structure inside the electronic compartment was simulated. Taking into account factors such as temperature, humidity, component stress, impact and vibration during product operation, the mechanical structure of the testing equipment was designed. The design of the testing equipment is similar to the internal structure of the compartment and has good fixation and stability.

[0057] Considering the need for insertion and removal within the testing equipment, the tooling must possess extremely high stability. Therefore, if... Figure 4 To stabilize the two frame bodies, two front and rear liner plates 8 were added, and surface treatment of the parts was required to increase strength and ensure the durability of the testing equipment. The adapter plate 5 can be easily installed on the lower end of the guide rail for easy disassembly. When the components are inserted, the stress on the adapter plate 5 can be "absorbed" by the liner plates on both sides and the right side wall of the rear control panel 2 with components, thus preventing strong deformation that could lead to breakage or twisting and affect the transmission stability of power signals and component simulated servo motors.

[0058] This invention connects the simulated rudder drive and simulated servo motor to the VG5, adapter board, and sensor data acquisition unit in the simulated electronic cabin. It sends and receives rudder input data via a computer and compares the data. If a sudden change in direction occurs, the sensor data acquisition unit can be troubleshooted in advance at its manufacturer's location. This proactive troubleshooting improves reliability, safety, and accuracy, and enables multi-component signal interaction and other functional integration testing, as well as compatibility testing between components. Furthermore, this invention simplifies all component testing processes, reduces product return rates, shortens production cycles, and improves testing efficiency.

[0059] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
