The invention discloses a transmission scheduling method for ensuring the service quality of real-time video transmission in a wireless multi-hop network. By dividing the video file according to the transmission and processing capabilities of the multi-hop links in the network, and sending them to the target node from multiple paths in sequence, the ratio of each code stream can be transcoded on each link and arrive in order receiving node. By eliminating the mutual waiting of each code stream on each link to avoid the problem of out-of-order and reordering of data packets at the receiving end in traditional multi-path transmission, effectively reducing the startup delay and buffer requirements of the receiving end, and enabling real-time playback .

The invention relates to an intelligent detection system for cotton fiber moisture, which includes a signal generator module, a digital temperature sensor, a capacitive reactance sensor, and a data conditioning circuit module. Connect and act on the capacitive sensor, and at the same time connect the output signals of capacitance, temperature, and the distance between the plates to the input terminal of the data conditioning circuit module, and then receive and input the signal amplified by the data conditioning circuit module into the data acquisition card , the signal after data conditioning is collected by the data acquisition card, and sent to the upper computer, and the upper computer software platform performs data processing, and calculates and displays the moisture content of cotton fiber in real time. The computer is an external host computer, and LABVIEW virtual instrument software is installed at the same time. It improves the accuracy of calculating the moisture content of cotton fiber, and at the same time uses the virtual instrument platform to improve the real-time processing performance, and can further enable the cotton fiber moisture detection to realize remote online control and data sharing.

The invention discloses an array radar simulator. The array radar simulator includes a main board, an interface board and a storage board; the main board is used for obtaining a FLASH erasing instruction, a FLASH writing instruction and a FLASH reading instruction, and receiving and sending array radar echo signals in real time, wherein the array radar echo signals are sent by the interface board; the interface board is used for successively receiving the FLASH erasing instruction, the FLASH writing instruction and the FLASH reading instruction, and obtaining the array radar echo signals in real time, so as to obtain low-electric level FLASH erasing gating signals, low-electric level FLASH writing gating signals and low-electric level FLASH reading gating signals, and then converting the array radar echo signals into N channels of cache array radar echo signals; the storage board is used for receiving and storing the N channels of cache array radar echo signals, the low-electric level FLASH erasing gating signals, the low-electric level FLASH writing gating signals and the low-electric level FLASH reading gating signals in real time, sequentially carrying out FLASH erasing, FLASH writing and FLASH reading operation, sequentially obtaining a FLASH erasing completion instruction, a FLASH writing completion instruction, a FLASH reading completion instruction and N channels of cache FLASH array radar echo signals, and storing the FLASH erasing completion instruction, the FLASH writing completion instruction, the FLASH reading completion instruction and the N channels of cache FLASH array radar echo signals in real time.

The invention discloses a wheeze sound multi-channel detection airway excitation tester and a method for picking up and applying the wheeze sound, comprising a drug atomization device, several pickups for picking up the wheeze sound, and a device for collecting the wheeze sound A controller for amplification processing, analog-to-digital conversion, synchronous conversion, and calculation processing of signals input by the pickup and electrode patches, and an output device, which is electrically connected to the controller for image display, audio playback, and electronic medical record printout. Since the pickup is set, the wheezing sound can be collected, and the wheezing sound can be picked up; because the controller, memory and output device are set, the collected signal is processed by the controller, and the generation of the wheezing sound is judged and analyzed. , and synchronize the wheezing sound with the respiratory waveform, the storage of the wheezing sound can be realized through the memory, and the playback, restoration, real-time recording, marking and printing of the wheezing sound can be realized through the output device due to the setting of the output device.

The invention provides a seamless continuous playing method of traveling television audios on a cellphone. After being away from a television, the cellphone judges wifi (wireless fidelity) access points and switches correspondingly through a local area network of a plurality of routers according to strength of router signals in the local area network so as to guarantee instantaneity of reception and playing of the audios. During switching process of the wifi access points, a television stores audio data temporarily, and after a cellphone terminal sends sharing requests again, seamless continuous playing is performed according to breakpoints. Even if a user needs to be away from the television, he or she can also bring away the television audios, real-time playing of the television audios is achieved. In the same local area network (namely, when the television is connected to a main router and the cellphone is connected to the main router again through a subordinate router.), the real-time audios of the television are brought to a farther place and are played seamlessly and continuously through router transferring under a condition of allowing the audios to stop transiently.

The disclosure provides a global simultaneous interpretation method and related products. The method includes the following steps: the smart phone receives a call request sent by a terminal, connects the call request, and establishes a call connection; the smart phone receives the first call sent by the call connection. Voice information, when identifying the first voice information and determining that the first voice information is not in the set language, translate the first voice information into the second voice information in the set language; the smart phone passes the second voice information through the sounding device play. The technical solution provided by the application has the advantage of high user experience.

The invention provides a streaming media broadcast system, a streaming media broadcast method and an LED display screen system. The streaming media broadcast system comprises a streaming media processing module; the streaming media processing module comprises a code source control submodule, an inner core submodule, and a video processing submodule; the code source control submodule comprises a receiving processing unit and a first data-caching mechanism; the inner core submodule comprises an audio / video separating unit, a video decoding unit and a second data-caching mechanism; the video processing submodule comprises a video processing unit and a third data-caching mechanism. According to the invention, streaming media broadcast on an asynchronous control system for an LED display screen is realized; as a three-level data-caching mechanism technology is adopted in the design of the media player, the fluency of real-time media video broadcast is improved; conditions of blocking and nonfluency are reduced.
