System and method for detection of container presence on chassis

A method of detecting whether a container is mounted on a transport chassis using a chassis-mounted device, comprising:

• transmitting a mmWave signal upwards from a mounting location on the transport chassis and receiving a reflected signal;
• identifying a plurality of peaks in the reflected signal;
• determining that a highest peak is reflected from a first distance outside a container range;
• determining that a second highest peak is reflected from a second distance within the container range and at a magnitude greater than a minimum threshold, thereby indicating a detected container;
• determining, based on the first distance and the second distance whether the highest peak is a multipath reflection;
• and
• transmitting a message to a remote server via a wireless communication system reporting detection of a container and the multipath reflection;
• initiating short-range wireless pairing with a container-mounted asset tracking device in response to the detected container;
• obtaining a unique identifier from the container-mounted asset tracking device;
• and
• transmitting, to the remote server, the unique identifier and an identifier of the device indicating an association between the container-mounted asset tracking device and the device.

A non-transitory computer-readable medium storing processor-executable instructions to detect whether a container is mounted on a transport chassis using a device configured to transmit a mmWave signal upwards from a mounting location on the transport chassis and to receive a reflected signal, wherein the instructions, when executed, are to cause the processor to:

• identify a plurality of peaks in the reflected signal;
• determine that a highest peak is reflected from a first distance outside a container range;
• determine that a second highest peak is reflected from a second distance within the container range and at a magnitude greater than a minimum threshold, thereby indicating a detected container;
• determine, based on the first distance and the second distance whether the highest peak is a multipath reflection;
• and
• transmit a message to a remote server via the wireless communication system reporting detection of a container and the multipath reflection;
• initiate short-range wireless pairing with a container-mounted asset tracking device in response to the detected container;
• obtain a unique identifier from the container-mounted asset tracking device;
• and
• transmit, to the remote server, the unique identifier and an identifier of the device indicating an association between the container-mounted asset tracking device and the device.
