The invention provides a transponder aging test system comprising message reading-writing tools, multi-channel C interface output tools, an upper computer and serial port servers. The upper computer communicates with the message reading-writing tool by the serial port server. Each transponder corresponds to one message reading-writing tool; and the message reading-writing tools are able to carry out message reading and writing testing on default message parts of passive transponders or active transponders. Built-in messages are arranged in the multi-channel C interface output tools; and the multi-channel C interface output tools are controlled to be turned on or off by upper computer software and send messages to the active transponders. The upper computer software controls on/off of message sending of the multi-channel C interface output tools and controls the message reading-writing tools to carry out message reading and writing testing. The system is able to monitor the running states of multiple transponders in real time; high-efficiency batched aging testing is realized; and the integration of the system is improved greatly.

The invention is suitable for the technical field of vehicles, and provides a vehicle information transmission method and device, electronic equipment and a storage medium. The method comprises the steps: obtaining a data obtaining request sent by an upper computer in a first communication format; analyzing the data collection request, and determining a to-be-communicated target ECU and to-be-collected target ECU data; according to the target ECU data, generating a data request message in a second communication format corresponding to the target ECU, and sending the data request message to the target ECU; receiving a response message sent by the target ECU based on the data request message; and analyzing the response message to obtain target ECU data, converting the target ECU data into reply information in the first communication format, and sending the reply information to the upper computer. According to the scheme, the requirement for professional knowledge of developers during vehicle data collection based on the vehicle-mounted Ethernet is lowered, and the development difficulty of upper computer software is lowered.

The present invention relates to a web-based computer system, a web-based computer software for use in connection with the web-based computer system, and a method of use thereof for the transfer of information between a moderator and a plurality of recipients in a face-to-face environment. In the system, a presentation such as a series of sequential questions are programmed into the interface for use in a face-to-face setting. A moderator tasked with transferring information to listeners in proximity uses a large display such as a plasma television connected to the internet to display questions, data, or group answers.

The invention provides a bus information extraction device of a rudder system in a loop and a semi-physical simulation method. The extraction device comprises an industrial personal computer, a 1553Bbus acquisition and optical fiber transmission interface board, a matched cable and an optical fiber; the industrial personal computer and the 1553B bus acquisition and optical fiber transmission interface board are jointly accessed into a CPCI/PCI bus; the 1553B bus acquisition and optical fiber transmission interface board is used for connecting the bus information extraction device into a 1553Bbus in a bus monitor mode through a matched cable; the 1553B bus is connected with a plurality of RT terminals including a rudder system and a guidance machine, and the 1553B bus acquisition and optical fiber transmission interface board is connected with the simulation system through an optical fiber. According to the invention, via the control of the FPGA transmission scheduling control module,the real-time rapid extraction and synchronous conversion of 1553B bus information can be realized and transmitted to an optical fiber network; the invention is small in time delay and stable in frame period, and solves the problems that the existing master-slave 1553B bus interface computer software is large in data acquisition and forwarding time delay and easily causes divergence of a simulation test.
