[0031] System Implementation Examples

[0032] According to embodiments of the present invention, an analysis system for a light weapon center of mass measurement system is provided. Figure 1 This is a schematic diagram of the analysis system of the light weapon center of gravity measurement system according to an embodiment of the present invention, as shown below. Figure 1 As shown, the analysis system of the light weapon center of mass measurement system according to an embodiment of the present invention specifically includes:

[0033] The data reading module 10 is used to read measurement data from multiple sensors uploaded by the inspection instrument. Specifically, the data reading module 10 uses the Modbus protocol, obtains the serial port of the inspection instrument using VISA, configures the serial port parameters, uses the VISA write function to send a host request command to the inspection instrument, and reads the measurement data uploaded by the inspection instrument through the slave response command returned by the inspection instrument. The host request command specifically includes: the slave response command specifically includes: a two-bit inspection instrument address, a two-bit read / write function code, a four-bit register address for channel one, a four-bit number of registers to be read, and a four-bit parity check code; the slave response command specifically includes: four-bit identification data, multiple sensor data, and a parity check code, wherein each sensor data is 4 bytes long.

[0034] The data separation and format conversion module 12 is used to extract the data corresponding to each sensor according to the measurement data and convert the data into single-precision floating-point numbers.

[0035] The software zeroing and data display module 14 is used to save the initial zero drift value of each sensor, and to perform software zeroing by subtracting the initial zero drift value from the real-time measurement value of the sensor. It also calls the data display module to display single-precision floating-point numbers and the center of gravity of the light weapon.

[0039] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] LabVIEW is a programming development environment developed by National Instruments (NI). Similar to C and BASIC development environments, LabVIEW differs significantly from other computer languages ​​in that it uses a graphical programming language (G) to generate code, producing block diagrams. LabVIEW software is the core of the NI design platform and is ideal for developing measurement or control systems. The LabVIEW development environment integrates all the tools engineers and scientists need to quickly build a wide range of applications, designed to help them solve problems, improve productivity, and innovate.

[0041] Like C and BASIC, LabVIEW is a general-purpose programming system with a vast function library capable of performing any programming task. LabVIEW's function library includes data acquisition, GPIB, serial port control, data analysis, data display, and data storage. LabVIEW also has traditional program debugging tools, such as setting breakpoints, displaying data and its subroutines (subVIs) results in animated fashion, single-step execution, etc., facilitating program debugging.

[0042] LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a graphical programming language that uses icons instead of lines of text to create applications. Traditional text-based programming languages ​​determine the execution order of programs based on the sequence of statements and instructions, while LabVIEW uses a dataflow programming approach. The data flow between nodes in the block diagram determines the execution order of VIs and functions. VIs refer to virtual instruments, which are program modules in LabVIEW. LabVIEW provides many controls that resemble traditional instruments (such as oscilloscopes and multimeters) for easy creation of user interfaces. The user interface in LabVIEW is called the front panel. Using icons and connections, objects on the front panel can be controlled programmatically. This is the graphical source code, also known as G-code. LabVIEW's graphical source code is somewhat similar to a flowchart, and therefore is also called block diagram code.

[0043] Based on the above advantages, this research scheme selects LabVIEW to develop a program for reading and analyzing the data measured by various sensors uploaded by the inspection instrument. The data reading and analysis process is as follows: Figure 2 As shown.

[0044] Depend on Figure 2 The system for reading and analyzing the center of mass data of light weapons can be divided into the following six parts: 1. Data reading, 2. Data separation, 3. Data format conversion, 4. Software zeroing and data display, 5. Calculation of center of mass and moment of inertia, and 6. Data storage. Specifically:

[0045] 1. Data reading module:

[0046] To read the measurement data uploaded by the inspection instrument, the computer must understand the instrument's data transmission protocol. The Modbus protocol is a common language used in electronic controllers. Through this protocol, controllers can communicate with each other and with other devices via networks (such as Ethernet). It has become a universal industry standard. With it, control devices from different manufacturers can be connected to form an industrial network for centralized monitoring.

[0047] This protocol defines a message structure that a controller can recognize and use, regardless of the network over which they communicate. It describes the process by which a controller requests access to other devices, how to respond to requests from other devices, and how to detect and log errors. It establishes a common format for message field layout and content.

[0048] When communicating on a Modbus network, this protocol dictates that each controller must know its device address, recognize messages sent at that address, and determine what action to take. If a response is required, the controller generates feedback information and sends it using the Modbus protocol. On other networks, messages containing the Modbus protocol are converted into frame or packet structures used on that network. This conversion also extends the methods for handling node addresses, routing paths, and error detection based on the specific network.

[0049] a. Query

[0050] The function code in the query message tells the selected slave device what function to perform. The data segment contains any additional information about the function the slave device is to perform. For example, function code 03 requests the slave device to read holding registers and return their contents. The data segment must contain information to tell the slave device: which register to start reading from and the number of registers to read. The error detection field provides the slave device with a way to verify the correctness of the message content.

[0051] b. Response

[0052] If the device generates a normal response, the function code in the response message is the same as the function code in the query message. The data segment includes data collected from the device, such as register values ​​or status. If an error occurs, the function code will be modified to indicate that the response message is erroneous, and the data segment contains codes describing this error information. The error detection field allows the master device to confirm whether the message content is valid.

[0053] c. Function codes

[0054] Different function codes correspond to different functions, as shown in Table 1.

[0055] Table 1, Function Codes

[0056] function code name effect 03 Read holding register Retrieve the current value from one or more holding registers. 04 Read input register Retrieve the current value from one or more input registers. 05 Preset single register Write data to a holding register

[0057] d. Command format

[0058] When the controller is configured to communicate in RTU (Remote Terminal Unit) mode on a Modbus network, each 8-bit byte in the message contains two 4-bit hexadecimal characters. The main advantage of this method is that it can transmit more data than ASCII at the same baud rate.

[0059] The code system is as follows:

[0060] 1. 8-bit binary, hexadecimal numbers 0...9, A...F;

[0061] 2. Each 8-bit field in the message consists of two hexadecimal characters forming the bits of each byte;

[0062] 3. One start bit;

[0063] 4. Of the 8 data bits, the least significant bit is sent first;

[0064] 5. No verification, then none;

[0065] 6. One stop bit;

[0066] 7. Error Detection Domain

[0067] 8. CRC (Cyclic Redundancy Detection)

[0068] e. Example of reading whole data using RTU method

[0069] Since the data collected by the inspection instrument is stored in the holding register, the 04 instruction set should be used to read the data, as shown in Tables 2 and 3.

[0070] Table 8, Host Requests

[0071]

[0072] Table 9, Slave Response

[0073] address function code byte count High byte of data Low byte of data CRC error check 01 04 2 41 24 XXXX

[0074] Based on the principles of the above communication commands, the host request command is 0104 0000 0008F1CC, where 01 is the address of the inspection device, 04 is the read / write function code, 0000 is the register address of channel one, 0008 is the number of registers to be read, and F1CC is the parity check code. The slave response command is 0104 + sensor 1 data + sensor 2 data + sensor 3 data + sensor 4 data + parity check code, with each sensor's data length being 4 bytes.

[0075] Since the inspection instrument connects to the computer via RS485 to USB, a serial port can be obtained using LabVIEW's VISA API. VISA is the standard I / O API for instrument programming, capable of controlling GPIB, serial, USB, Ethernet, PXI, or VXI instruments, and calling the appropriate driver based on the type of instrument used. Users do not need to learn the communication protocols of various instruments. VISA is independent of the operating system, bus, and programming environment; the same API is used regardless of the device, operating system, and programming language employed.

[0076] The serial port is acquired using VISA, and parameters such as serial port data bits, baud rate, timeout, terminator, stop bits, parity, and enable terminator are configured. Then, the VISA write function is used to send the master request command to the slave device. Finally, the validity of the command returned by the slave device is checked. The specific program design is as follows: Figure 3 As shown.

[0077] 2. Data separation and format conversion

[0078] Because the received data format is: 0104 + sensor 1 data + sensor 2 data + sensor 3 data + sensor 4 data + parity check, and each sensor data occupies 4 bytes, the data for sensor 1 corresponds to bytes 3 to 6, the data for sensor 2 corresponds to bytes 7 to 10, the data for sensor 3 corresponds to bytes 11 to 14, and the data for sensor 4 corresponds to bytes 15 to 18. Based on the register address of the character data, the data corresponding to each sensor is extracted, and the read string is converted into a single-precision floating-point number. Data separation and format conversion are as follows: Figure 4 As shown.

[0079] 3. Software zeroing and data display

[0080] The zero point of a load cell is easily affected by environmental factors, causing zero-point drift. To ensure the initial zero point, a software zeroing method is used. The idea is to save the initial zero-drift value of the sensor and then subtract this value from the real-time measurement value, thus achieving software zeroing. Data display directly calls the data display module. The software zeroing and data display correction procedures are as follows: Figure 5 As shown.

[0081] 4. Centroid Calculation

[0082] The calculation of the center of mass involves the pallet and auxiliary housing, as well as the light weapon being tested.

[0083] a. Calculation of the center of gravity of the pallet and auxiliary box

[0084] The auxiliary box includes a cuboid auxiliary box and a head model. The centroid coordinates (x) of the assembled body are calculated. c y c and z c This prepares for subsequent calculations of the center of gravity of small arms. For the convenience of z c The calculation simply requires rotating the box along the x-axis and z-axis, transforming x into z' and z into x', and then calculating x according to the formula. c The method to calculate z c The flowchart is as follows: Figure 6 As shown.

[0085] b. Calculation of the center of gravity of small arms

[0086] The center of mass of a small arms includes coordinates in the x, y, and z directions. When four sensors are on the same plane, the x and y coordinates of the center of mass can be obtained and the relevant data saved for calculating the z-coordinate of the center of mass. The measurement surface of the auxiliary housing is adjusted to calculate the z-coordinate of the center of mass. The procedure for calculating the center of mass coordinates is as follows: Figure 7 As shown.

[0087] 5. Transformation of the body's centroid coordinates

[0088] The coordinate transformation of the body's center of mass can be achieved by subtracting the coordinates of the box's center of mass from the coordinates of the light weapon's reference point. After the coordinate transformation, the position of the center of mass can be viewed in a three-dimensional or two-dimensional coordinate system.

[0089] 6. Data storage

[0090] To facilitate subsequent data processing, the measured coordinates of the light weapon's center of gravity need to be stored. Using LabVIEW's WriteDelimited Spreadsheet function, the following data are saved as an Excel file: light weapon number, mass of the tray and auxiliary box, center of gravity X0 of the tray and auxiliary box, center of gravity Y0 of the tray and auxiliary box, center of gravity X1 (center of gravity Z) of the tray and auxiliary box, center of gravity Y1 of the tray and auxiliary box, light weapon mass, center of gravity X of the light weapon, center of gravity Y of the light weapon, center of gravity Z of the light weapon, center of gravity X of the light weapon body, center of gravity Y of the light weapon body, and center of gravity Z of the light weapon body. Figure 8 As shown.

[0091] 7. Program Interface

[0092] The program interface consists of five functional modules: sensor measurement values, function selection, calculation of tray and auxiliary box parameters, calculation of light weapon center of gravity, and display of light weapon center of gravity coordinates. The final program interface is as follows: Figure 9 As shown.

[0093] a. Function Selection Module

[0094] Users can select the serial port to control data acquisition, system calibration, input light weapon numbers, display communication status, and save data.

[0095] b. Sensor measurement module

[0096] This module displays the real-time readings of four sensors as well as the readings after software zeroing, and also displays the sum of the sensor readings and the weight of the light weapon.

[0097] c. Pallet and Auxiliary Box Parameter Calculation Module

[0098] This module is used to calculate the mass and center of mass parameters of the toddler and auxiliary box. The "Parameter 0" button is used to calculate the center of mass coordinates X0 (X) and Y0 (Y) of the above combination, and the "Parameter 1" button is used to calculate the center of mass Y1 (Z).

[0099] d. Center of mass calculation for small arms

[0100] Users can calculate the center of gravity of the light weapon by controlling the calculation button, and convert the coordinates of the light weapon body by inputting a reference point. The default input value is (0, 0, 0).

[0101] e. Light Weapon Coordinate Display

[0102] This module can display the coordinate position of light weapons in three-dimensional space, and the position of the center of mass in the xy and xz two-dimensional coordinate systems, respectively. Figure 10 As shown.
