DTS.Common.Enums.Sensors Module Documentation

1. Purpose

This module provides the core enumerations, constants, and utility methods for sensor management within the DTS data acquisition system. It defines sensor lifecycle states, calibration behaviors, filter configurations, zero methods, CSV import/export field mappings, and various sensor-related constants. The module serves as a foundational layer for sensor configuration, validation, and data interchange across the application.

2. Public Interface

Enumerations

SensorChangeTypes

public enum SensorChangeTypes { OffsetTolerance }

Defines types of sensor changes. Currently only OffsetTolerance is defined.

SensorStatus

public enum SensorStatus { Available, InUse, OutForService, OutForCalibration, Retired }

Defines the lifecycle states of a sensor.

PossibleFilters

public enum PossibleFilters { All, Analog, Squib, DigitalIn, DigitalOut, UART, StreamOut, StreamIn, CAN }

Describes different ways of filtering channels and sensors by type.

NonLinearStyles

public enum NonLinearStyles { IRTraccManual, IRTraccDiagnosticsZero, IRTraccZeroMMmV, IRTraccAverageOverTime, Polynomial, IRTraccCalFactor }

Defines linearization formula styles for non-linear sensor processing.

3. Invariants

  1. CSV Version Range: Valid CSV import versions are between MIN_VALID_VERSION (0) and MAX_VALID_VERSION (6), inclusive.

  2. Sensor Tag Versions: Only versions 0, 2, 3, and 4 are considered "sensor tag" versions as defined in _SensorTagsVersions.

  3. Bridge Resistance Limits: Valid bridge resistance values must be between MIN_BRIDGE_RESISTANCE_OHMS (1) and MAX_BRIDGE_RESISTANCE_OHMS (32000).

  4. ZeroMethodType Enum Ordering: The order and explicit values of ZeroMethodType enum members must not be changed due to legacy compatibility requirements (e.g., GM ISF import).

  5. BridgeType Bitmask vs. Storage: BridgeType uses bitmask values (powers of 2), but database storage uses sequential integers (0-4, 8) via ConvertBridgeToInt.

  6. FilterClassType Values: Filter class values represent actual cutoff frequencies in Hz (e.g., CFC60 = 100 Hz, not 60).

  7. TSR AIR Channel Numbers: Humidity channel is channel 10, Pressure is channel 11, Temperature is channel 9 within TSR AIR atmospheric modules.

4. Dependencies

This module depends on:

  • System - Core .NET types
  • System.ComponentModel - TypeConverter, DescriptionAttribute
  • System.ComponentModel.DataAnnotations - DisplayAttribute
  • System.IO.Ports - StopBits, Parity, Handshake enums
  • System.Collections.Generic - Dictionary, HashSet, List
  • System.Linq - LINQ extension methods
  • DTS.Common.Converters - EnumDescriptionTypeConverter
  • DTS.Common.Attributes - DisplayAttribute, VersionAttribute (custom attributes)
  • DTS.Common.Base.Classes - DescriptionResourceAttribute

What depends on this module:

  • Unknown from source alone. This is a foundational enums/constants module likely used throughout the DTS application for sensor configuration, data acquisition, and import/export functionality.

5. Gotchas

  1. Static Property State: Many static properties in SensorConstants (e.g., UseInitSignalTOM, UseSensorFirstUseDate, DisableAutoSense) are described as "holding values between processes" and do not serialize/deserialize. They must be set by using applications on startup.

  2. ZeroMethodType Legacy Compatibility: The comment explicitly warns: "Lots of legacy compatibility (e.g. importing GM ISF) depends on the order/value of this enum." Do not reorder or reassign values.

  3. BridgeType Integer Conversion: The ConvertBridgeToInt method uses non-bitmask integer values for database storage, which is described as "needed for historical reasons." The mapping is not 1:1 with bitmask values (e.g., HalfBridge_SigPlus = 128 in enum but stores as 4).

  4. Deprecated SensorSettings: LimitDuration, Duration, and Delay in SensorSettings enum are marked as "deprecated in 2.1" but remain in the enum.

  5. FilterClassType None Behavior: Per comments, None = 0 has special behavior: "Code = P unless UseZeroForUnfiltered is True, then Code = 0". This behavior is not defined in this source file.

  6. Uninitialized Static Properties: UsageRemainingForWarning and DefaultMaxUsageAllowed are declared without initialization, implying they must be set before use.

  7. Test-Specific Serial Number Prefixes: Multiple similar prefixes exist (TEST_SPECIFIC_THERMO = "TST_" vs TEST_SPECIFIC_THERMOCOUPLER = "TST_TestSpecific"). The relationship between short prefixes and full serial formats is not fully documented in source.

  8. CSVImportTags Thread Safety: All public methods use lock(MY_LOCK) for thread-safe lazy initialization of lookup dictionaries.
