5、R Systems, Data 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 AS6135, Interface Standard, Airborne EO/IR Systems, Data, is a standard that defines the data interfa

6、ce 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 interchangeability1. This document was prepared by the AS-1C3 Electro-Optic/Inf

13、ERISTICS . 21 SAE AS6135 Page 3 of 33 1. SCOPE This standard defines the data interfaces between a host aircraft (“platform”) and an Electro-Optic/Infrared (EO/IR) sensor. These data interfaces cover various types of data including: imagery, metadata, command, status, and responses (CSR), geospatial

14、 postion, time, test and maintenance, and hand-controller. This standard does not cover mechanical or electrical interfaces. 1.1 Relationship Between Aircraft/Sensor Interfaces and SAE Standards Figure 1 shows the relationship between the various interfaces and the various SAE standards. AS6129 (ele

15、ctrical) covers connectors, power, conductors, fiber optics, and some aspects of data transport. AS6135 (data) covers data (e.g., imagery, metadata, as well as CSR). AS6135 overlaps AS6129 in the area of protocols for data transport. AS6135 and AS6129 are closely bound together because building a sy

16、stem 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. NOTE: Regarding Figure 1, SAE is drafting a standard (AS6165) to cover maintenance and test which will overlap both AS612

17、9 and AS6135. SAE is also drafting a standard (AS6169) which will cover the mechanical interface. AS6169 will overlap AS6129 with regard to connectors. FIGURE 1 - RELATED SAE STANDARDS 1.2 Purpose The intent of this standard is to enhance interoperability, commonality, and interchangeability among e

18、quipment provided by various EO/IR suppliers and avionic systems. Adoption of this standard will improve procurement flexibility for acquisition, system integrators, and platform providers. Relevant platforms include fixed wing, rotary wing, UAS (except for micro-UAS), and lighter than air vehicles.

19、 The approach adopted to accomplish these intents includes utilizing the same interface standards used elsewhere in the end-to-end system. This standard is also intended to encourage the move away from sensors that use interlaced acquisition, transport and/or format, as well as analog interfaces. Th

20、e data interface is designed to facilitate the: a. Interconnection between EO/IR sensor systems and the avionics systems hosted by the platform b. Exchange of data and metadata between sensor systems and sensor data processors c. Maintenance and test of EO/IR systems SAE AS6135 Page 4 of 33 1.3 Appl

21、ication This standard applies to all platforms and EO/IR sensors that interface with each other. AS6135 addressess turreted EO/IR sensor systems. Future revisions of AS6135 may address other EO/IR sensor systems such as pods. AS6135 covers sensors and platforms presently in concept development stage

22、s, future platforms, and sensor developments, and upgrades to legacy platforms. This standard is intended for use by procuring agencies and as a general guideline for industry. 2.

45、erein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 2.3 Definitions COMMAND, STATUS, AND RESPONSE INTERFACE: Defines the data elements and message sets passed between the host

46、platform and the sensor used to control the operation of the sensor. This interface may also be used to check sensor operation. The protocol for passing these messages is handled in co-ordination with the AS6129. AS6129 also covers the requirements for conductors/fiber optics. The following types of

47、 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 directs its operation. These instructions come from an operator, from the aircraft, or from a pre-programmed set of

48、instructions. These commands, for example, 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-location; change magnification to X; display black as hot versus white hot; turn on image fusion; etc. b.

49、 STATUS: Digital information returned from the EO/IR sensor back to the operator, aircraft, or recorder which provides feedback on sensor operation and other indications of its condition. Examples of this information include: magnification level, azimuth and elevation, stabilization setting, output scale setting for thermal sensors, heading, etc. Another example is the Built-In Test (BIT) information which might occur periodically, in res
