The invention discloses a medical data processing method based on the Internet of Things. The method comprises the steps: firstly carrying out the sensing of a signal of a medical sensing node throughthe Internet of Things, obtaining the Internet of Things information transmitted by the medical sensing node, and carrying out the compression measurement of the Internet of Things information; collecting and arranging the compression measurement signals of the medical sensing nodes through a convergence processing module, and transmitting the compression measurement signals to a data analysis and processing center; and finally, the data analysis and processing center recovers the data. Lossless compression and recovery of the information data of the Internet of Things are realized. The storage space and power consumption of the sensing nodes can be effectively saved. The energy efficiency ratio of the whole network is improved.
