US 11,529,916 B1 · Multiplexing sensor data

Abstract

The described techniques relate to a simulation system that multiplexes sensor data from multiple sensors and outputs the multiplexed sensor data in channels corresponding to the multiple sensors to appropriate vehicle systems at an appropriate time based on encoded timestamp data. In examples, a multiplexer may receive sensor datasets associated with different sensors. The multiplexer may encode the different sensor datasets with timestamp data and supplemental data to generate an encoded dataset. The multiplexer may output the encoded dataset to a video output port to transmit the encoded dataset to a demultiplexer. The demultiplexer receives the encoded dataset from the video output port, and separates the encoded dataset into channels corresponding to the sensors from which the sensor data was received. The demultiplexer may output the datasets in the respective channels at a time (or times) indicated in the timestamp data and according to the supplemental data.

Dependent claims

A system comprising:

a multiplexer configured to:
receive a first data set associated with a first sensor and a second data set associated with a second sensor;
and
encode the first data set and the second data set with timestamp data and supplemental data to generate an encoded data set, wherein the supplemental data further comprises at least one of a frame type, a frame size, or a fault injection parameter configured to simulate a sensor fault;
a video output port communicatively coupled to the multiplexer to transmit the encoded data set from the multiplexer;
and
a demultiplexer communicatively coupled to the video output port and configured to:
receive the encoded data set from the video output port;
separate the encoded data set into a first channel of data comprising the first data set and a second channel of data comprising the second data set;
and
output at least one of the first channel of data or the second channel of data to a vehicle system indicated in the supplemental data and at a time indicated by the timestamp data.
