Abstract: The present disclosure relates to data transmission methods. One example method includes receiving, by a receive end, at least two streams from a transmit end, where each stream of the at least two streams includes a plurality of data packets, each data packet carries a stream identifier of a stream to which the particular data packet belongs and a stream data sequence number, and the stream data sequence number indicates a sequence of the particular data packet in the stream to which the particular data packet belongs, for at least one of the at least two streams, determining, by the receive end, that a data packet whose stream data sequence number meets a sequential condition has been received, and submitting, by the receive end, the data packet whose stream data sequence number meets the sequential condition.

Abstract: An intelligent grinding device for short pulse electrical melt chip removal cooling, includes a diamond grinding wheel, a pulse power supply, a force meter sensor, thermocouple in a hole of work piece for measuring machining temperature, a voltage sensor, a current sensor, a temperature collecting card, a charge amplifier, a force meter, a digital oscilloscope and a discharge parameter feedback adjustment system. The pulse power supply has a positive pole connecting with the grinding wheel, and a negative pole connecting with the work piece. The voltage sensor and the current sensor respectively put collected discharge voltage and current wave of the discharge circuit to be stored in a display terminal through the digital oscilloscope. The thermocouple connects with the display terminal by the temperature collecting card.
