firstly, acquiring real-time air pressure P in a spine protection air bag strip 1 in an equal frequency mode by using a basic data acquisition unit 2, and carrying out average value processing on the real-time air pressure acquired in a preset time period T-wait to obtain air pressure data Pm;
and then setting a change threshold value as delta P, and judging that the real-time sleep state of the user is asleep when the delta P is less than Pm-Pm-1 for j times continuously, otherwise, judging that the real-time sleep state of the user is awake.
By carrying out average processing on the real-time air pressure collected within the preset time period T-wait, the influence of artificial artifacts or individual error data on the calculation of the processor is effectively eliminated, and the judgment accuracy of the processor is improved. The amplitude of the air pressure change in the adjacent preset time periods is judged by setting a change threshold value delta P, when the Pm-Pm-1 is less than the delta P for j times continuously, the user moves less, the real-time sleep state of the user is judged to be sleep, otherwise, the real-time sleep state of the user is judged to be clear, and the preset time period times with the change amplitude smaller than the delta P are counted again.
In actual operation, j is 5 times, the accuracy of the real-time sleep state is effectively judged, and in addition, the value of the parameter j can meet the requirement that j is more than or equal to 3 times and less than or equal to 8 times.
In actual operation, the T-wait is 3s, the accuracy of the real-time sleep state is effectively judged, and in addition, the value of the parameter T-wait meets the requirement that the T-wait is more than or equal to 1s and less than or equal to 5 s.
In actual operation, the data acquisition frequency of the basic data acquisition unit 2 is C, and C is 15 times/second, so that the accuracy of the real-time sleep state is effectively judged, and in addition, the value of the parameter C only needs to meet the requirement that C is less than or equal to 25 times/second and is less than or equal to 5 times/second. When T-wait is 3s and C is 15 times/second, 45 real-time air pressures P can be acquired in a preset time period T-wait, so that the average air pressure corresponding to the preset time period is obtained, and the processor is convenient to calculate the real-time sleep state of a user.
In actual operation, the spine protection system is detachably installed on the mattress, specifically, the air pressure adjusting assembly carrying the processor is externally arranged on the mattress, the spine protection air bag strip is placed on the top surface of the mattress, the spine protection air bag strip is controlled by the air pressure adjusting assembly to inflate and deflate to realize hardness adjustment, and therefore traction and relaxation of the lumbar of a user are achieved. The spine protection system can be carried out, and is convenient to use in temporary residences such as hotels. The air pressure adjusting component can be connected with an external commercial power, and can also be provided with a rechargeable battery, which are all regarded as specific embodiments of the invention.
