The invention discloses a vehicle data collection method and device, a storage medium and electronic equipment, and the method comprises the steps: collecting a CAN message in a vehicle CAN bus, wherein the CAN message comprises a plurality of message frames and the network segment identification information of each message frame; converting the CAN message into a big data message in an SOMEIP protocol format according to the network segment identification information of each message frame; wherein each big data message comprises N SOMEIP data items, the N SOMEIP data items are obtained by converting N first message frames with the same network segment identification information, each big data message further comprises first network segment identification information corresponding to the first message frames, and N is an integer greater than or equal to 1; and sending the big data message to a remote communication terminal. As the conversion of the message format occurs in each domain controller, the remote communication terminal only needs to receive the big data message, so that the requirements on CAN interface resources and hardware computing power of the remote communication terminal are low, the hardware cost of the remote communication terminal does not need to be increased, and the efficient and flexible acquisition of the whole vehicle data can be realized.

The present disclosure provides a chip on-orbit reconfiguration method, device, equipment and storage medium, which can be applied to the field of FPGA on-orbit reconfiguration technology. The method comprises: in response to receiving a reconfiguration instruction sent by a management end, running the reconfiguration instruction to erase data in a target address region of a first storage chip indicated by the reconfiguration instruction; returning feedback information indicating that the data erasure has been completed to the management end; writing a configuration data packet into the target address region of the first storage chip; running a restart instruction to control a service chip to enter a restart state, wherein the service chip is configured to send a resource loading instruction to a master control chip in response to being in the restart state; and in response to the resource loading instruction based on the interface timing of a second storage chip connected to the service chip, the configuration data packet is sent to the service chip, wherein the service chip is configured to perform on-orbit reconfiguration based on the configuration data packet.

The invention relates to the technical field of audio processing, and discloses a method for optimizing echo double talks in a reflection environment, a mobile terminal and a storage medium, the method comprises the following steps: in a hand-free call process, controlling a motor to vibrate for a preset duration; collecting a vibration signal generated by vibration of the motor; comparing the collected vibration signal with a preset reflection environment characteristic signal; and selecting an audio parameter according to a comparison result. By acquiring amplitude characteristics and / or spectrum characteristics of the vibration signals for comparison, a hard reflecting surface and a soft reflecting surface can be distinguished, and corresponding optimized audio parameters are selected. According to the method, the motor and the microphone of the mobile terminal are utilized, hardware cost does not need to be increased, whether the mobile terminal is in the reflection environment or not can be detected, the audio parameters are dynamically adjusted according to the detection result, the echo double-talk effect in the reflection environment is equivalent to that in a handheld scene, and the hand-free call quality is remarkably improved.
