5、rne EO/IR Systems, Electrical RATIONALE This document was created to standardize the data interface between aircraft and EO/IR sensors. This activity was initiated at the request of the U.S. Navy in 2009. PREFACE AS6129, Interface Standard, Airborne EO/IR Systems, Electrical, is a standard that defi
6、nes the electrical interface between aircraft (manned and unmanned) and onboard EO/IR Systems. Its purpose is to promote platform to sensor system interface standardization by providing substantial, but not 100% commonality, interoperability, and interchangeability. This document was prepared by the
7、 AS-1C1 Electro-Optic/Infrared Signal Sets Task Group, under the jurisdiction of the AS-1C Subcommittee, Avionic Subsystems, of the SAE AS-1 Committee, Platform Systems and System Integration.

SCOPE This standard defines a
21、 generic set of electrical interfaces between a host aircraft (“platform”) and an electro-optic/infrared (EO/IR) sensor. This includes connectors, cabling, fiber optics, signals, and power. 1.1 Relationship Between Platform/Sensor Interfaces and SAE AS-1C Standards Figure 1 shows the relationship be
22、tween the various interfaces and the various SAE standards. AS6129 (electrical) covers connectors, conductors and fiber optics signals, and power, and some aspects of data transport. AS6135 (data) covers data (e.g., imagery, metadata, as well as command, status, and response messages.). AS6135 overl
23、aps AS6129 in the area of protocols for data transport. AS6135 and AS6129 are closely bound together because building a system based on these standards is dependent on the requirements from both standards. Also, requirements put in one standard can impact the options for updating the other standard.
24、 NOTE: Regarding Figure 1, SAE is drafting a standard to cover maintenance and test which, if adopted, will likely overlap both AS6129 and AS6135. SAE is also drafting a standard to cover the mechanical interface which, if adopted, will overlap AS6129 with regard to connectors. FIGURE 1 - RELATED SA
25、E STANDARDS 1.2 Purpose The intent of this standard is to enhance interchangeability and interoperability amongst equipment provided by various EO/IR Suppliers and avionic systems. Adoption of this standard will improve procurement flexibility for system integrators and platform providers. Platform
26、providers include fixed wing, rotary wing, UAS (except for micro-UAS) and lighter than air vehicles. The interfaces are designed to facilitate the: a. operation of EO/IR sensor electrical and mechanical subsystems; b. interconnection between EO/IR sensor systems and the avionics systems hosted by th
27、e platform; c. exchange of data and metadata between sensor systems and sensor data processing; d. maintenance of EO/IR systems, allowing for reduction in maintenance equipment in the field and for test. SAE AS6129 Page 4 of 51 1.3 Application This standard applies to all platforms and EO/IR sensors
28、 that interface with each other. AS6129 addresses turreted EO/IR sensor systems. Future revisions of AS6129 may address other classes of EO/IR sensor systems such as non-gimbaled sensors and podded sensors. This standard is intended for application to future sensors and platforms. This includes evol
29、utionary modifications as well as completely new designs. This standard is intended for use by procuring agencies, and as a general guideline for industry. 2.

SAE AS6129 Page 6 of 51 2.3 Definitions COMMAND, STATUS, AND RESPONSE INTERFACE - Defines the data elements and message sets passed between the host platform and the sensor used to control the operation of the sensor. The protocol for passi
45、ng these messages is handled in co-ordination with the groups which specify the messages. The following types of information are passed through the Command, Status, and Response interface: a. COMMANDS - The set of all digital instructions transmitted to the EO/IR Sensor from the controller which dir
46、ects its operation. These instructions come from an operator, from the platform, or from a pre-programmed set of instructions. These Commands instruct the EO/IR sensor where to point, and which features to utilize in gathering images, such as: slew left; turn on stabilization; lock onto a geo-locati
47、on; change magnification to X; display black as hot versus white hot; turn on image fusion; etc. b. STATUS - Digital information returned from the EO/IR sensor back to the operator, platform, or recorder which provides feedback of sensor operation and other indications of its condition. Examples of
48、this information include: magnification level, azimuth and elevation, stabilization setting, output scale setting for thermal imaging sensors, heading, etc. Another example is the Built-In Test information which might occur periodically, in response to a command, or only if a fault or warning is det
49、ected. Status information can overlap with metadata. c. RESPONSES: Digital information returned from the EO/IR sensor back to the operator, platform, in reply or reaction to a command. Responses are a sub-set of Status. For example, if the command is to turn on stabilization, the response is “stabilization is on”. ELECTRONIC CONTROL UNIT (ECU) - An electronic unit logically between the platform and the sensor, typically inside the platfo
