US 12,684,051 B2 · Data transmission method and electronic device

Abstract

A data transmission method and an electronic device are provided. One uplink interface and one downlink interface are deployed on each input device of the electronic device. The uplink interface is connected to a processor or an upper-level input device, and the downlink interface is connected to a lower-level input device. A processing module in each input device may process image data collected by the current-level device and data sent by a lower-level input device connected to a downlink interface, and then transmit processed data to the processor or an upper-level input device through an uplink interface. Thus the plurality of input devices are connected in a cascade manner, and only one of the plurality of input devices needs to be connected to the processor.

Dependent claims

A method, comprises:

after receiving a first instruction sent by a processor, receiving, by a first camera module, a first data packet sent by a second camera module, wherein the first data packet comprises a first identification field, a value of the first identification field in the first data packet indicates a quantity of forwarding times of the first data packet, and the first data packet is received through a first downlink interface of a first physical layer of the first camera module;
identifying, by the first camera module, that the value of the first identification field in the first data packet is a first value, and modifying the first value to a second value to obtain a modified first data packet, wherein a difference between the second value and the first value is a preset value;
and
sending, by the first camera module, the modified first data packet to the processor through a first uplink interface of the first physical layer of the first camera module.

1 more element

An electronic device, comprising:

a processor;
a first camera module;
and
a second camera module;
wherein the first camera module is configured to:
after receiving a first instruction sent by the processor, receive a first data packet sent by the second camera module, wherein the first data packet comprises a first identification field, a value of the first identification field in the first data packet indicates a quantity of forwarding times of the first data packet, and the first data packet is received through a first downlink interface of a first physical layer of the first camera module;
and
identify that the value of the first identification field in the first data packet is a first value, and modify the first value to a second value to obtain a modified first data packet, wherein a difference between the second value and the first value is a preset value;
and
send the modified first data packet to the processor through a first uplink interface of the first physical layer of the first camera module.

7 more elements

A non-transitory computer-readable storage medium, comprising instructions, wherein when the instructions are run on a camera module, the camera module is enabled to act as a first camera module and to perform:

after receiving a first instruction sent by a processor, receiving a first data packet sent by a second camera module, wherein the first data packet comprises a first identification field, a value of the first identification field in the first data packet indicates a quantity of forwarding times of the first data packet, and the first data packet is received through a first downlink interface of a first physical layer of the camera module;
identifying that the value of the first identification field in the first data packet is a first value, and modifying the first value to a second value to obtain a modified first data packet, wherein a difference between the second value and the first value is a preset value;
and
sending the modified first data packet to the processor through a first uplink interface of the first physical layer of the camera module.
