The invention provides ultrasonic diagnosis equipment and a method for reducing ultrasonic echo data interference. The method comprises the following steps: periodically transmitting multi-line echo data by controlling an ultrasonic probe; transmitting one line echo data in one transmission period, wherein each transmission period comprises a first time period and a second time period, and the transmission of each line echo data is completed in the second time period of each transmission period; and transmitting a part of the first information in the first time period of the transmission period, so that the first information and the multi-line echo data are transmitted in a time-sharing manner. Therefore, the echo data is not interfered when the first information is transmitted, the interference source of the echo data is reduced, and the quality of ultrasonic images is improved.

The invention discloses an intelligent LED street lamp, which includes several intelligent street lamp single lamps. The intelligent street lamp single lamps include: a type 1 single lamp and a type 2 single lamp, and a gateway controller and an integrated controller in the two constitute an intelligent street lamp Local area network, the intelligent street lamp local area network is based on the radio frequency wireless communication mode of 780MHz, with the server as the main station, the integrated controller as the substation, and the gateway controller as the base station to form the basic layout of the star network architecture, which not only ensures that there are few wireless channel interference sources, The signal transmission is stable and reliable, and at the same time, it also ensures the consistency in time of issuing operating commands such as switching lights and dimming. The on-site control effect is uniform and there is no obvious delay. , gateway controller, centralized controller, and data acquisition module can not only accept adjustment instructions from the control terminal, but also collect environmental information as feedback to realize intelligent city management.

This invention provides a testing method for the engine winch's rotation angle and speed, it includes taking advantage of a signal processing cell, which can calculate the winch dynamic sampling signal from the gear information sensing by the sensor of the winch's rotating angle. Taking advantage of the scatter dynamic model, it can design an estimate cell including the estimator and feedback attenuation matrix to read the dynamic sampling signal of the winch, and work toward to the estimating rotating angle and speed in the close circuit current. This invention also consists of taking advantage of the judging cell for the rotation of the winch which can assistant the signal processing cell to accurately calculate the dynamic signal of the winch, and reduce the interface from the outside and reduce the effectiveness of the engine controlling.

The invention belongs to the technical field of millimeter wave communication and instrument control system, and in particular relates to a millimeter wave wireless instrument control system. The present invention is composed of a terminal equipment module, an intelligent control station module, a data center module, a millimeter wave digital transmission module, and an optical fiber backbone module. The measuring instrument device transmits the data information to be sent to the millimeter wave digital transmission module, and the millimeter wave digital transmission module will The information is sent to the intelligent control station through the millimeter wave. The intelligent control station analyzes the received information and transmits it to the remote data center module through the optical fiber backbone. The data center module receives the data information from the instrument device and analyzes it. After processing, the issued instructions are transmitted to the intelligent control station through the optical fiber backbone, and the intelligent control station then sends the instruction information to the execution device through the millimeter wave. Finally, the execution device completes the instruction, which overcomes the confusion of the traditional wired instrument control line and maintenance. Difficulty, not conducive to extended maintenance and other issues.
