The invention provides a data transmission method, a vehicle and electronic equipment, and relates to the technical field of automobile communication. The method comprises the following steps: sending an address book data acquisition request for an address book to a mobile terminal; receiving address book basic data returned by the mobile terminal based on the address book data acquisition request, wherein the address book basic data comprises other contact data except the contact head portrait data; sending a head portrait data acquisition request to the mobile terminal based on the address book basic data; and receiving contact head portrait data returned by the mobile terminal based on the head portrait data acquisition request. According to the embodiment of the invention, the reachable time of the vehicle address book function can be shortened, the user experience is improved, the data transmission efficiency is improved, and the data processing pressure of the vehicle is relieved.

The application discloses a microwave optical aperture conversion staring receiving system and method for optical domain desquamation, and belongs to the technical field of radar systems. The system comprises a local reference light generation module introduced on an existing digital beam forming radar receiver, which is used for generating a local optical reference signal by suppressing a single sideband modulation of another light signal output by a light source module. An optoelectronic detection and collection module is also introduced, which is used for collecting complete target echo light signals output by the optical Fourier transform module through an optoelectronic detector array. Meanwhile, the local optical reference signal and the target echo light signals achieve collinear space matching on a photosensitive surface of the optoelectronic detector array, and the two signals generate beat frequency. The square law detection characteristic of the optoelectronic detector is used to realize mixed frequency optical domain desquamation receiving of the target echo light signals. The target echo light signals received by the mixed frequency optical domain desquamation are used for simultaneously detecting the azimuth and distance of multiple targets.

The invention particularly relates to a WEB picture downloading method and system, and belongs to the technical field of picture display.The method comprises the steps that a picture folder is generated in a WEB offline state, a downloading instruction is sent, and the picture folder comprises picture data, mapping data and event data; and receiving a downloading instruction and the picture folder in the WEB running state, and downloading according to the picture folder on the user interface to generate a target picture. The system implements the steps of the method. According to the invention, the resource occupation is reduced, the business conflict risk is reduced, and the processing efficiency is improved.

This invention provides a vehicle status data processing method and apparatus. The method includes: acquiring the current status data of a target vehicle; extracting first low-frequency status data from the status data based on a pre-configured list of low-frequency change fields; and, if the first low-frequency status data is inconsistent with second low-frequency status data, sending the first low-frequency status data to a low-frequency topic in a message middleware. The second low-frequency status data is extracted from the previous status data of the target vehicle based on the list of low-frequency change fields. This invention extracts low-frequency status data based on a pre-configured list of low-frequency change fields and sends the current low-frequency status data to the message middleware only when the low-frequency status data changes. This significantly reduces the transmission of redundant data, greatly reduces the data processing pressure on downstream consumer components and server resource consumption, and achieves efficient data diversion and refined management of vehicle data.

The application discloses a dust remover blowing event data collection method and system, and relates to the technical field of dust remover data collection. When the first pulse valve action in a blowing sequence corresponding to a target collection object is detected, the blowing ash removal cycle is determined to start, and the multi-source operation signals associated with the target collection object are synchronously collected in the blowing ash removal cycle. The lifting valve state at the start of the blowing ash removal cycle is used to determine the blowing type. When the preset ending condition is met, the blowing ash removal cycle is determined to end. The dust remover blowing event data collection method and system adopt a multi-mode data strategy combining periodic uploading and event triggered uploading. The low frequency statistical summary uploading is used for regular monitoring to maintain system baseline monitoring, and the complete original waveform data is uploaded for deep diagnosis in the key blowing ash removal and opening box events.
