Description

Technical Field

[0001] This invention belongs to the field of airborne suspension deployment technology, specifically relating to a pneumatic parameter acquisition system and method for configurable multi-unit suspension deployment devices. Background Technology

[0002] Multi-mounted launchers, as critical load-bearing devices on aircraft, play a vital role in flight and combat. To improve equipment versatility, current multi-mounted launchers need to carry various types of targets. When carrying different targets, because the targets have different separation attitude requirements, it is necessary to use regulating pins to adjust the airflow parameters of the multi-mounted launcher's air path during ground loading to control the launch of different targets and meet their separation attitude requirements.

[0003] Currently, in multi-unit suspended deployment devices, the method for collecting the angle of the adjusting pin is to install microswitches around the adjusting pin. When the adjusting pin is rotated to different angles, the switching state of the microswitches changes accordingly, thereby collecting the air circuit parameters.

[0004] Several limitations exist in using this method. First, the installation position of the microswitches needs to be strictly controlled to ensure that they only engage when the adjusting pin is rotated to a specific position. This places high demands on the structural design and assembly of the multi-unit suspended delivery device. Second, to provide feedback on different pneumatic parameters via the microswitches, multiple microswitches need to be installed around the adjusting pin, requiring thicker cables to connect them and increasing the complexity of the control system that acquires the microswitch signals. Finally, due to limitations in control system space, cable placement, and electrical connector locations, this method is only suitable for multi-unit suspended delivery devices with a limited number of mounting positions and a limited range of compatible suspended objects. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a pneumatic path parameter acquisition system and method for a configurable multi-unit suspended delivery device, which is integrated within the multi-unit suspended delivery device.

[0006] This invention proposes a pneumatic parameter acquisition system for a configurable multi-unit suspended delivery device. This system, installed within the device, includes a sensor array, a CAN bus communication matrix, a data processor, and a high-speed data transmission network. The sensor array employs angular displacement sensors to detect the rotation angle of the adjusting pins in each pneumatic path in real time. The sensor array and the data processor are connected via the CAN bus communication matrix. The data processor has a debugging interface through which configuration information of the sensor array is sent. The data processor then sequentially sends the configuration information to the required angular displacement sensors. The data processor receives angular displacement data from the CAN bus, converts it into the rotation angle of the adjusting pins, and transmits it to a host computer via the high-speed data transmission network.

[0007] Advantageously, the configuration information includes ID, initial angle state, baud rate, and sampling period.

[0008] Advantageously, the data processor includes a bus communication module, a data processing module, a data storage module, and a high-speed bus communication module.

[0009] Advantageously, the bus communication module is used for CAN bus communication.

[0010] Advantageously, the data processing module is used to convert the CAN bus data sent by each angular displacement sensor to obtain the rotation angle information of the corresponding adjustment pin, and send it to the data storage module.

[0011] Advantageously, the data storage module is used to store the rotation angle information of the measured adjustment pins on each mounting position after calculation, and send it to the high-speed bus communication module.

[0012] Advantageously, the rotation angle information of the adjusting pin is updated every 50ms in the data storage module.

[0013] Advantageously, the high-speed data transmission network includes a GJB289A bus terminal for connecting to a host computer via the GJB289A bus.

[0014] This invention also proposes a method for acquiring air path parameters of a configurable multi-unit suspended delivery device, using the aforementioned air path parameter acquisition system. The method includes the following steps: S1. Determine the air path to be used and the adjustment pin to be tested based on the deployment task of the multi-unit suspension delivery device and the type of suspended object at each mounting position. S2. The configuration information of the sensor group is sent to the data processor, and the data processor sequentially sends the configuration information to the angular displacement sensor of each adjustment pin, including the ID, initial angle state, baud rate and sampling period of each angular displacement sensor. S3. Rotate the adjusting pins respectively and send the rotation angle of the adjusting pins to the data processor in real time. The data processor determines whether the angle of the adjusting pins meets the deployment parameter requirements and sends it to the host computer.

[0015] Advantageously, if the angle of the adjusting pin is in the middle position, it is not suitable for any kind of hanging object.

[0016] Beneficial effects: This invention fills the gap in the technical field of configurable multi-unit suspended delivery device air path parameter acquisition system. Through this invention, the air path parameter acquisition system of multi-unit suspended delivery device is simplified, effectively reducing the size and complexity of related systems. It achieves a breakthrough in the number of mounting positions and the number of types of suspended objects that can be used in the air path parameter acquisition system of multi-unit suspended delivery device, and can collect the compatibility information of 55 mounting positions and no less than 18 types of suspended objects per mounting position. Attached Figure Description

[0017] Figure 1 This is an electrical principle block diagram of the present invention.

[0018] Figure 2 This is an example of an angular displacement sensor using a CAN bus ICD. Detailed Implementation

[0019] See Figure 1 The air path parameter acquisition system shown is a configurable multi-unit suspended delivery device, including a sensor group, a CAN bus communication matrix, a data processor, and a high-speed data transmission network.

[0020] The multi-unit suspension deployment device includes multiple mounting positions, each with one or more air passages, and each air passage has an independent adjusting pin. An air passage parameter acquisition system is installed within the multi-unit suspension deployment device, and its sensor array includes angular displacement sensors for detecting the rotation angle of each adjusting pin, collecting the rotation angle information of the adjusting pins, and transmitting it in CAN bus data format.

[0021] The sensor group and the data processor are connected via a CAN bus communication matrix. The data processor has a debugging interface through which configuration information is sent to the data processor, and the data processor then sends the configuration information to the required angular displacement sensors in sequence. The configuration information includes ID, initial angle state, baud rate, and sampling period.

[0022] The data processor includes a bus communication module, a data processing module, a data storage module, and a high-speed bus communication module. The bus communication module is used for CAN bus communication. The data processing module converts the CAN bus data sent by each angular displacement sensor to obtain the rotation angle information of the corresponding adjusting pin, and sends it to the data storage module. The data storage module stores the calculated rotation angle information of the measured adjusting pins on each mounting position, updates it every 50ms, and reports the changes to the host computer via a high-speed data transmission network through the high-speed bus communication module until the air path controlled by the rotation angle of the adjusting pin meets the deployment requirements of the corresponding suspended object.

[0023] The high-speed data transmission network includes one GJB289A bus terminal, which is used to connect to the host computer via the GJB289A bus to report the information of the suspended objects adapted to each hanging position of the multi-unit suspended delivery device.

[0024] The configuration method of the multi-unit suspension delivery device's air path parameter acquisition system is as follows: By assigning different IDs to N1 angular displacement sensors, a single CAN bus network is used to connect the N1 angular displacement sensors and data processor 3, effectively distinguishing messages from different sensors. This allows for the configuration of the number of mounting positions for which air path parameters need to be collected. Based on the characteristics of the CAN bus and current usage patterns, theoretically, N1 can be 110. Considering the current usage, this corresponds to 55 mounting positions. By configuring the calculation method and pre-setting the correspondence between the adjustment pin rotation angle of each of the N2 mounting positions and the compatible suspended objects, the number of types of suspended objects that can be adapted to each mounting position can be configured.

[0025] The method for collecting the air circuit parameters of the multi-unit suspension delivery device is to calculate the rotation angle of the adjusting pin in the multi-unit suspension delivery device through a data fusion algorithm to obtain the current air circuit parameters. Then, by comparing the air circuit parameters with the preset correspondence of the adapted suspension object, it is determined whether the adjusting pin is in place. The information is updated every 50ms, and when the information changes, the change is reported to the host computer through a high-speed data transmission network.

[0026] The workflow is as follows: First, clarify the air path parameters that need to be collected in the multi-unit suspended delivery device. Here, we assume that rotating the adjusting pin clockwise by 15° is state 1, clockwise by 37° is state 2, and counterclockwise by 43° is state 3. State 1, state 2, and state 3 respectively enable the delivery of suspended object 1, suspended object 2, and suspended object 3.

[0027] Secondly, according to Figure 2 The air path parameter acquisition system of the multi-unit suspension deployment device is configured accordingly, specifically the angular displacement sensor group.

[0028] The following example, using the operation of the No. 2 angular displacement sensor, illustrates the configuration method.

[0029] The data processor sends the data shown in Table A1 to the angular displacement sensor via the CAN bus, configuring it as sensor number 2.

[0030] Table A12 Sensor ID Configuration Message

[0031] Then send the message shown in Table A2, configuring the median value.

[0032] Table A22 Sensor Median Configuration Message

[0033] After the above two configuration steps, the angular displacement sensor has been configured as an angular displacement sensor with a CAN bus baud rate of 500Kps, a transmission period of 50ms, an ID number of 2, and a median value of the current state. It will be referred to as sensor number 2 below.

[0034] Sensor 2 is installed at the adjusting pin 1 of the mounting position 1 to collect the rotation angle of adjusting pin 1.

[0035] After the system is powered on, the adjusting pin 2 sends the current angle (initially, sending the data corresponding to 95°) via the CAN bus at a period of 50ms. The data is shown in Table B1.

[0036] Table B12 Sensor Initial Status Message

[0037] When the adjusting pin 1 of mounting position 1 rotates, the corresponding output changes. When the adjusting pin is in an intermediate state other than state 1, state 2, and state 3, the data processor will report to the host computer that mounting position 1 is not suitable for any type of hanging object.

[0038] When the adjusting pin 1 rotates 15° clockwise, the data sent by the sensor 2 is shown in Table B2.

[0039] Table B22 Sensor Status 1 Message

[0040] Upon receiving the message, the data processor calculates that the current sensor 2 is rotating 15° clockwise, corresponding to state 1, and reports to the host computer that the current mounting position 1 can accommodate the suspended object 1.

[0041] When the adjusting pin 1 rotates 37° clockwise, the data sent by the sensor 2 is shown in Table B3.

[0042] Table B32 Sensor Status 2 Message

[0043] Upon receiving the message, the data processor calculates that sensor 2 is currently rotating 37° clockwise, corresponding to state 2, and reports to the host computer that the current mounting position 1 can accommodate the suspended object 2.

[0044] When the adjusting pin 1 is reversed by 43°, the data sent by the sensor 2 at this time is shown in Table B4.

[0045] Table B42 Sensor Status 3 Message

[0046] Upon receiving the message, the data processor calculates that sensor 2 has rotated 43°, corresponding to state 3, and reports to the host computer that the current mounting position 1 can accommodate the suspended object 3.
