A data transmission method, intelligent terminal and radar system

Abstract

The invention relates to a data transmission method, comprising the following steps: step A: configuring a register for controlling the state of a LOCK pin of a deserializer; step B: enabling the interrupt of the LOCK pin of the deserializer through the register; step C: detecting LOCK Whether the pin state changes, if it changes, an interrupt signal is generated and output to the control processor; if there is no change, then cycle step C; step D: after the control processor receives the interrupt signal, the input pin corresponding to the deserializer is disabled; And step E: the deserializer disables the input pin to output black screen data, and the other input pins output normally. In the data transmission method of the present invention, the LOCK pin is enabled and interrupted by the deserializer configuration register, an interrupt signal is generated by using the state change of the LOCK pin, and the control processor disables the corresponding input pin of the deserializer according to the interrupt signal, It can quickly realize the normal output of the deserializer when the camera is disconnected.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission method, an intelligent terminal and a radar system. Background technique [0002] The existing solution of multiple cameras (for example: four cameras) co-deserializer generally uses multiple channels of video data to be converted into serial data through a serializer, and then deserialized through the same deserializer to form multiple channels. Deserialize data, each channel of deserialized data is independently output to ISP (Image SignalProcessor, image processor) through CSI (CMOS Serial Interface, camera serial interface) for processing into image data, and finally the image data is transmitted to the control processor Data processing and output to the display terminal. [0003] Existing deserializers generally work in synchronous mode. When one of the cameras fails to disconnect, because the deserializer uses synchronous mode, the deserialize...

AI Technical Summary

Problems solved by technology

[0003] Existing deserializers generally work in synchronous mode. When one of the cameras is faulty and disconnected, since the deserializer uses synchronous mode, the deserializer cannot monitor multiple cameras that share the same ISP (for example: two cameras) ) data to be synchronized, so that multiple cameras sharing the same ISP output black screen images, resulting in poor image quality after processing by the control processor
