Standard Practice for Implementing Communications Impairments on A-UGV Systems

Importancia y uso:

4.1 A-UGVs operate in a wide range of indoor and outdoor applications that include many communications challenges that can affect A-UGV control and monitoring. An A-UGV system or A-UGVS as defined in Terminology F3200 includes the A-UGV and all associated components, equipment, software, and communications necessary to make a fully functional system. Communications impairments can cause: (1) changes in A-UGV operation, (2) changes in behavior in system components such as control and scheduling, or (3) changes in operation or timing of infrastructure equipment coordination. This practice is intended to record the task performance of an A-UGV while communications are impaired in a specified and repeatable manner (for example, standard test method).

4.2 Communications impairments can occur at a variety of locations within the A-UGVS. The network topology in Fig. 1 shows many of the common communications links that could be impaired. The numbered arrows in Fig. 1 label different places where communications impairments could occur. The box colors (that is, green, red, blue) indicate different types of impairments where the two red boxes are similar to each other. Fig. 1 will be used throughout this practice and included on the test report for use in describing the test setup and results by the test supervisor.

4.3 The requested expected results provide pass/fail reporting criteria along with recorded notes pertinent to the test or results or both. It is possible that the communications impairments used will have no noticeable effect, and this is often the desired outcome.
