[0069] Figure 12 A flowchart illustrating the method based on the second example is shown. Detailed Implementation

[0070] Figure 1 A diagram illustrating a connector 10 for connecting a sensor to a data logger is shown. Connector 10 stores data (e.g., calibration data) that can be read by the data logger to facilitate operation between the sensor and the data logger. Connector 10 can be a discrete electronic device (such as a plug), wherein the components of connector 10 are housed within a connector housing (e.g., as shown in the diagram). Figure 5 (As illustrated in the illustration). Alternatively, connector 10 may be part of another device (such as a hub), wherein components of connector 10 are housed within the housing of the other device (e.g., as shown in the illustration). Figure 7 (As illustrated in the examples). See below for further details. Figure 8 and Figure 9 To describe the data logger and sensor in more detail.

[0071] Connector 10 includes circuitry 12 and memory 14. Circuitry 12 is configured to receive signal 16 from a sensor and transmit digital signal 18 to a data logger. Signal 16 can be an analog signal or a digital signal. In an example where signal 16 is a digital signal, circuitry 12 may not modify signal 16; therefore, circuitry 12 can be a wire, cable, or printed circuit board (PCB) trace. In other examples, circuitry 12 can modify signal 16 and may therefore include one or more electronic components (referencing below) for performing the modification. Figures 2 to 4 (As described).

[0072] Memory 14 can be any suitable non-transitory computer-readable storage medium, one or more data storage devices, and may include hard disks and / or solid-state storage (such as flash memory). Memory 14 can be a permanent, non-removable memory or a removable memory (such as a secure digital card). Memory 14 stores one or more of the following: sensor configuration data 20; or sensor calibration data 22. Memory 14 may also store sensor historical data 24. The data logger can directly read data 20, 22, and 24 from memory 14 (e.g.,...). Figure 1 (As indicated by arrow 26 in the image), or data 20, 22, 24 can be read via circuit 12 (e.g., ...). Figure 1 (As indicated by arrow 28 in the image).

[0073] Sensor configuration data 20 defines the settings for the sensor and can define how the data logger will read the sensor. For example, sensor configuration data 20 can define the frequency at which the data logger will read the sensor (e.g., a reading at 1 Hz). As another example, sensor configuration data 20 can define the calibration interval for the sensor (i.e., the maximum time period between sensor calibrations). Sensor configuration data 20 can also define the protocol, filter settings (analog / digital), excitation (voltage, current, AC), sampling rate, and resolution (e.g., unnecessary resolution can be reduced to decrease memory usage).

[0074] Sensor calibration data 22 defines how the data generated by the sensor will be modified (with the aim of improving the accuracy of the sensor-generated data). For example, sensor calibration data 22 may define that the sensor-generated data (e.g., through addition, subtraction, multiplication, or division) is modified by a fixed value. As another example, sensor calibration data 22 may define how the sensor-generated data is modified according to a linear or nonlinear algorithm. Sensor calibration data 22 may also include coefficients for converting binary data to engineering units (EU) and contain constraints, such as amplitude limits on vibration sensors, temperature compensation, etc.

[0075] Sensor history data 24 is a record of the sensor's history. For example, sensor history data 24 may record one or more dates on which sensor calibration data 22 was modified. As another example, sensor history data 24 may record one or more dates on which sensor configuration data 20 was modified.

The analog front-end 30 is configured to receive analog signal 16 from a sensor and perform signal conditioning on the analog signal 16. For example, the analog front-end 30 may perform one or more of the following operations: voltage limiting; current limiting; or anti-aliasing filtering of the analog signal 16 to provide the conditioned analog signal 34.

[0078] The analog-to-digital converter (ADC) 32 may include any suitable circuitry and may include, for example, an integrated circuit, such as a metal-oxide-semiconductor (MOS) mixed-signal integrated circuit. The ADC 32 may be a Σ-Δ ADC, a successive approximation ADC, or a continuous-time Σ-Δ ADC. The ADC 32 is configured to receive a regulated analog signal 34 from the analog front end 30 and convert the regulated analog signal into a digital signal 18.

In some examples, the first contact 36 may include a photodiode to enable the reception of optical signals from an optical fiber cable.

[0081] The second contact 38 is connected to the analog-to-digital converter 32 and is configured to be electrically connected to the data logger (e.g., arranged as a plug and socket). The second contact 38 may also be connected to the memory 14.

[0082] Figure 4 A diagram illustrating a connector 103 for connecting a sensor to a data logger according to a fourth example is shown.

[0083] Processor 40 may include any suitable processor circuitry and may include, for example, a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or a microcontroller. Processor 40 is connected to analog-to-digital converter 32, memory 14, and second contact 38. Processor 40 is configured to receive digital signal 18 from analog-to-digital converter 32 and provide the processed digital signal to a data logger via the second contact 38. Processor 40 may be configured to read from and write to memory 14, and may be configured, for example, to write sensor history data 24 to memory 14. Processor 40 may also be configured to process digital signal 18 (e.g., by performing engineering unit conversions or by adjusting the amplitude / frequency content of the limit check signal).

[0084] Figure 5 A diagram illustrating a connector 104 for connecting a sensor to a data logger according to a fifth example is shown. Connector 104 is similar to connectors 10, 101, 102, and 103, and uses the same reference numerals where features are similar. Connector 104 includes circuitry 12, a memory 14, a first contact 36, a second contact 38, and a housing 42. Circuitry 12 may have the same characteristics as in... Figures 1 to 4 The circuit 12 described in any of the preceding paragraphs has the same structure. The memory 14 stores one or more of the following: sensor configuration data 20; or sensor calibration data 22, and the memory may also store sensor history data 24.

As used herein, a “parameter” of a propulsion system refers to any characteristic that helps define or classify the propulsion system. In other words, a “parameter” of a propulsion system can be a numerical value or other measurable factor that forms a set with other such parameters that define the operating conditions of the propulsion system. Such parameters can include mechanical parameters (e.g., component velocities, vibrations, and strain), electrical parameters (e.g., potential differences and currents), and thermodynamic parameters (e.g., temperature and pressure at different locations).

[0103] For example, the first sensor 96 may be a pressure sensor configured to monitor pressure at a first position of the gas turbine engine, the second sensor 98 may be a thermocouple configured to monitor temperature at a second position of the gas turbine engine, and the third sensor 110 may be a vibration sensor configured to monitor vibration at a third position of the gas turbine engine.

The second contact 38 of the connector 104 is connected to the contact 80 of the data logger 74.

[0107] Energy storage device 119 is configured to supply power to components of system 92. For example, energy storage device 119 may supply power to data logger 74, and data logger 74 may distribute power to connector 104, hub connector 94, hub 52, first sensor 96, second sensor 98, and third sensor 110. Energy storage device 119 may be any suitable device and may include batteries or supercapacitors.

[0108] It should be understood that system 92 can include any number of sensors (including a single sensor), and Figure 9The diagram illustrates only three sensors as examples. Similarly, system 92 may include more than one connector 104 and more than one hub 52. In some examples, system 92 may include one or more hubs 52, but may not include any connectors in connector 104. In other examples, system 92 may include one or more connectors 104, but may not include any hubs 52.

[0109] from Figure 9 It should be understood that hub 52 can advantageously enable an increase in the number and type of sensors, which can be connected to data logger 74 without requiring a change to the interface of data logger 74.

[0110] Figure 10 A diagram illustrating a propulsion system 120 including system 92 according to an example is shown. Propulsion system 120 may include one or more of the following: a gas turbine engine; one or more reciprocating engines; or one or more electric motors. Propulsion system 120 may be coupled to a vehicle to provide thrust and / or electricity to the vehicle. Examples of vehicles include aircraft, automobiles, boats, and locomotives.

[0111] The propulsion system 120 may also include a health monitoring system 122. The health monitoring system 122 is configured to generate data for multiple parameters of the propulsion system 120. The system 92 is also configured to generate data for one or more parameters of the propulsion system 120. However, at least one of the one or more parameters to be monitored by the system 92 may be different from the multiple parameters to be monitored by the health monitoring system 122. In other words, the system 92 may be configured to monitor at least one parameter in the propulsion system 120 that the health monitoring system 122 cannot monitor.

[0112] Deploying system 92 can take less time than deploying health monitoring system 122. Similarly, removing system 92 can take less time than removing health monitoring system 122. For example, where health monitoring system 122 and system 92 are connected to propulsion system 120 via fasteners (such as nuts and bolts), system 92 may require fewer fasteners to tighten and loosen than health monitoring system 122.

[0113] With another example, when health monitoring system 122 and system 92 are installed in propulsion system 120, system 92 can be installed in a more accessible location than health monitoring system 122, thus enabling faster deployment and removal. With another example, system 92 has fewer electrical connections to disconnect than health monitoring system 122, and therefore can be deployed and removed in less time. In some examples, because system 92 requires a lower level of clearance than health monitoring system 122 (e.g., less paperwork and processes), the deployment and / or removal of system 92 can take less time than the deployment and / or removal of health monitoring system 122. System 92 can be referred to as a troubleshooting toolkit.

[0114] Figure 11 A flowchart illustrating a method according to a first example is shown. At block 124, the method includes receiving one or more of the following from a memory connected to a connector of a sensor: sensor configuration data or sensor calibration data. For example, data logger 74 may receive one or more of the following from a memory 14 of connectors 10, 101, 102, 103, 104 (or hub 52) connected to sensors 96, 98, 110: sensor configuration data 20 or sensor calibration data 22. In some examples, block 124 may additionally include receiving sensor history data from the memory of a connector. For example, data logger 74 may receive sensor history data 24 from the memory 14 of connectors 10, 101, 102, 103, 104 (or hub 52).

[0115] At block 126, the method includes reading the connectors to receive digital signals. Where block 124 includes receiving sensor configuration data, block 126 may include using the received sensor configuration data to read the connectors to receive digital signals. For example, the processor 76 of the data logger 74 may use the received sensor configuration data 20 to read connectors 10, 101, 102, 103, 104 (or hub 52) to receive digital signals 18, 72.

[0116] At block 128, the method includes processing the received digital signal. Where block 124 includes receiving sensor calibration data, block 128 may include processing the received digital signal using the received sensor calibration data. For example, the processor 76 of the data logger 74 may use the received sensor calibration data 22 to process the received digital signal.

[0117] At block 130, the method includes controlling the storage of data in the processed digital signal in the memory of the data recorder. For example, the processor 76 of the data recorder 74 can control the storage of data in the processed digital signal in the memory 78 of the data recorder 74 (in... Figure 8 (Marked by reference numeral 132 in the attached icon). Figure 9 In the example, box 130 may include the storage of control pressure data, temperature data, and vibration data in memory 78.

[0118] At block 134, the method includes controlling the transmitter to send the stored data from the data logger. For example, the processor 76 of the data logger 74 may control the transmitter 84 to send the stored data 132 (e.g., as a wireless signal) from the data logger 74.

[0119] At block 136, the method includes controlling the storage of sensor history data in the connector's memory. For example, the processor 76 of the data logger 74 may control the storage of sensor history data (e.g., the date on which sensor calibration data was created) in the memory 14 of connectors 10, 101, 102, 103, 104 (or hub 52). In some examples, the processor 40 of connector 103 may control the storage of sensor history data in the memory 14 of connector 103.

[0120] System 92 and its components (such as connectors 10, 101, 102, 103, 104) can provide several advantages.

[0121] System 92 can be set up relatively quickly. Specifically, the sensors in System 92 do not require any manual configuration or calibration because when connectors 10, 101, 102, 103, and 104 are connected to data logger 74, data logger 74 can read sensor configuration data 20 and sensor calibration data 22. This facilitates changes between different sensor types and between transient and dynamic data recordings at data logger 74.

[0122] In addition, connectors 10, 101, 102, 103, 104 and hub 52 can be manufactured, calibrated and configured in the same facility or by the same manufacturer, which enables higher quality control and lower life cycle costs.

[0123] The analog front-end 30, analog-to-digital converter 32, and processor 40 can advantageously offload processing from the data logger 74 and reduce the processing workload of the processor 76.

[0124] As mentioned above, system 92 enables the monitoring of one or more parameters of propulsion system 120 that cannot be monitored by health monitoring system 122. This is advantageous when propulsion system 120 malfunctions and the data received from health monitoring system 122 fails to diagnose the malfunction.

[0125] The ability to quickly deploy and remove system 92 as needed or desired can also be advantageous, as this allows health monitoring system 122 to be minimized. Specifically, the sensor array of health monitoring system 122 can be configured to have only sensors for basic parameters, and system 92 can be deployed when it is desired to monitor non-basic parameters.

[0126] Furthermore, the ability to quickly deploy and remove system 92 as needed or desired can be advantageous, as this can be performed while propulsion system 120 is installed on the vehicle (i.e., deployment and removal can be performed in situ). This can help maximize the availability of the vehicle for operation.

[0127] Providing a dedicated processor 76 for system 92 may be advantageous because processor 76 may not need to meet a high design guarantee level (such as Design Guarantee Level A (DAL-A)). This allows for the use of higher-powered and commercial off-the-shelf (COTS) processors for processor 76. Such a processor could be capable of performing a wider variety of computations (including more demanding algorithms such as machine learning algorithms) and could be less expensive than the processor in health monitoring system 122.

[0128] A removable and handheld portable memory 78 can be advantageous because it allows for the rapid transfer of data 132 stored on the memory 78. For example, a person at an airport can relatively quickly remove the memory 78 without removing any other components of the system 92 and transfer the data 132 to another computer (e.g., a laptop computer). This process can take less time than transferring data to a computer via cable.

[0129] Providing a wireless transmitter 84 may be advantageous because such a transmitter enables the rapid transmission of data 132 stored on memory 78. For example, data 132 can be automatically and wirelessly transmitted when transmitter 84 enters the range of a receiver at an airport. This process can take less time than transmitting data 132 to a computer via cable or via a removable memory as described in the preceding paragraphs.

[0130] The energy storage device 119 can advantageously supply electrical energy to the components of system 92. Therefore, system 92 can operate independently of propulsion system 120 and health monitoring system 122. Furthermore, since system 92 does not require an electrical connection to the power supply of propulsion system 120, system 92 can be deployed and removed more quickly relative to health monitoring system 122 (which can be connected to the power supply of propulsion system 120).

[0131] Figure 12 A flowchart illustrating the method based on the second example is shown.

[0132] At block 138, the method includes determining whether the connector is electrically connected to the data logger. For example, the processor 76 of the data logger 74 can control the application of voltage to the contact 80 (by...). Figure 8 Arrow 139, as illustrated, indicates the direction of current flow to pin 51 of the second contact 38. If processor 76 determines that current is flowing, it determines that an electrical connection exists between data logger 74 and connector 104. If processor 76 determines that no current is flowing, it determines that no electrical connection exists between data logger 74 and connector 104.

[0133] At block 140, the method includes controlling an isolator to disconnect in response to determining that a connector is not electrically connected to the data logger. For example, a processor 76 of the data logger 74 may control an isolator 82 to disconnect in response to (e.g., by determining that pin 51 is not present) determining that connector 104 is not electrically connected to the data logger 74. In this configuration, isolator 82 isolates the processor 76 from connected connectors 10, 101, 102, 103, 104, or hub 52.

[0134] At block 142, the method includes controlling an isolator to be electrically connected in response to determining that a connector is electrically connected to a data logger. For example, a processor 76 of data logger 74 may control an isolator 82 to be electrically connected in response to (e.g., by determining the presence of pin 51) determining that connector 104 is electrically connected to data logger 74. In this configuration, isolator 82 allows data to flow from connectors 10, 101, 102, 103, 104 and hub 52 to processor 76.

[0135] exist Figure 12 The method illustrated above can advantageously enable the processor 76 to place the interface of the data logger 74 in a protected state when the interface (i.e., one or more connectors 80) is open.

[0136] Various examples have been described, each of which includes one or more combinations of features. Those skilled in the art will understand that any feature may be used alone or in combination with any other feature unless clearly mutually exclusive, and that the invention extends to and includes all combinations and sub-combinations of the one or more features described herein.
