As shown in fig. 1, the method for live video broadcast and data collection from end to end of an automobile comprises the following steps:
in step S101, a remote video instruction sent by a user is received.
The user can send a remote video instruction through a mobile phone APP (Application).
In step S102, a video capture device of the vehicle is turned on according to the remote video instruction, and live video data captured by the video capture device is acquired.
Optionally, acquiring live video data acquired by a video acquisition device includes: detecting a current state of the vehicle; if the current state is the awakening state, directly acquiring live broadcast video data; if the current state is the engine running state, acquiring video data of a vehicle event data recorder in the video acquisition equipment to generate live broadcast video data; if the current state is an engine stop state, operating any device in the video acquisition equipment according to the instruction of the mobile terminal to generate live video data; and if the current state is the sleep state, controlling the vehicle to be powered on and exiting the sleep state.
Specifically, when the vehicle receives the mobile phone APP instruction forwarded by the TSP; if the whole vehicle is in an awakening state, the intelligent vehicle machine module judges the current vehicle state, if the whole vehicle is in an engine, only an AVR (automobile data recorder) video is collected in an operation mode, and if the engine is in a stopping state, any video source is watched in an operation mode; if the whole vehicle is in a dormant state, the wireless communication module is awakened, the intelligent vehicle machine is awakened by the wireless communication module, and the TSP issues an instruction to the intelligent vehicle machine; the intelligent vehicle machine sends a control instruction to the vehicle body control module to carry out power-on operation after receiving the instruction issued by the TSP, judges the voltage value of the current storage battery, allows the video plug to be started if the voltage value is larger than a preset voltage value, the engine is in a non-working state, and the vehicle is in a fortification state, feeds back an execution result to the TSP after the intelligent vehicle machine detects that the power-on is successful, and initiatively accesses the TSP through a network to obtain detailed information of the instruction.
In step S103, the live video data is sent to a preset terminal of the user, and the vehicle is controlled to execute a corresponding protection action according to a preset condition.
The preset terminal can be an electronic device such as a mobile phone or a tablet, the preset condition can be an actual running state of the vehicle identified according to the live video data, and other conditions can also be set, which are not specifically limited herein.
Specifically, after the smart on-board live broadcast module obtains ICE (Interactive Connectivity information) information of itself, the ICE information may be reported to the TSP, and data is forwarded to a preset terminal, such as a smart phone, through the TSP; meanwhile, the smart phone acquires self ICE information, reports TSP and TSP to forward data to the vehicle live broadcast module, the smart car on-board live broadcast module and the mobile phone APP live broadcast module, end-to-end direct connection is carried out according to the respectively received ICE information, and an encryption instruction channel is created to transmit control instructions (such as transmitting various files, instructions and states) when the end-to-end direct connection is utilized.
