if the number of the first used storage units reaches the maximum number of the storage units, the detection result is no idle storage unit;
and if the number of the first used storage units is determined to not reach the maximum storage unit number, the detection result is an idle storage unit.
The used storage units in the first shared storage area can be defined as the number of first used storage units, when detecting whether the first shared storage area for storing the information has free storage units, whether the number of the first used storage units reaches the maximum number of the storage units in the first shared storage area can be determined, and if the number of the first used storage units reaches the maximum number of the storage units, which indicates that all the storage units included in the first shared storage unit store the information, the detection result is no free storage unit; and if the number of the first used storage units is determined to be less than the maximum number of the storage units, which indicates that part of the storage units included in the first shared storage unit stores information, the detection result is an idle storage unit.
Specifically, before the timer is started based on the sleep duration in S23, the method further includes:
if the information to be stored is acquired from the outside, storing the information to be stored into a first shared storage area, and adding 1 to the number of the first used storage units; or,
and if the information to be stored is acquired from the second shared storage area, subtracting 1 from the number of the second used storage units in the second shared storage area, and adding 1 to the number of the first used storage units.

and if the detection result is that no idle storage unit exists, adding 1 to the second continuous times, resetting the first continuous times, and adjusting the sleep time length according to the second continuous times, the set times and the maximum value.
The selection of the selected parameters is different according to different detection results, if the detection result is that an idle storage unit exists, the selected parameters comprise a first continuous time, a set time and a minimum value, the first continuous time for which the idle storage unit is detected is added with 1, and after a second continuous time for which no idle storage unit is detected is cleared, the sleep time length is adjusted according to the first continuous time, the set time and the minimum value; and if the detection result is that no idle storage unit exists, selecting parameters including a second continuous time, a set time and a maximum value to adjust the sleep time length, adding 1 to the second continuous time, resetting the first continuous time, and adjusting the sleep time length according to the second continuous time, the set time and the maximum value.
Specifically, the adjusting the sleep duration according to the first continuous times, the set times and the minimum value specifically includes:
determining whether the first continuous times exceed the set times after adding 1;
if the first continuous times are determined to exceed the set times after being added with 1, determining whether the sleep duration is smaller than the minimum value after being reduced by the set value;
if the sleep duration is determined to be reduced by the set value and then is smaller than the minimum value, updating the sleep duration to the minimum value; and if the sleep duration is determined to be not less than the minimum value after being reduced by the set value, reducing the sleep duration by the set value.
The detection result is an idle storage unit, so that whether the first continuous time plus 1 exceeds the set time or not needs to be determined, if the first continuous time plus 1 exceeds the set time, the first shared storage area has idle storage space for multiple times, the sleep time can be shortened to store information, the sleep time can be reduced, at the moment, whether the sleep time is reduced by the set value or not needs to be further determined, and specifically, if the sleep time is reduced by the set value and is smaller than the minimum value, the sleep time is updated to the minimum value; and if the sleep duration is determined to be not less than the minimum value after being reduced by the set value, reducing the sleep duration by the set value.
The setting value may be set according to actual needs, and may be, for example, but not limited to, set to 100ms.
Specifically, the adjusting the sleep duration according to the second continuous times, the set times and the maximum value specifically includes:
determining whether the second continuous times exceed the set times after adding 1;
if the second continuous times exceed the set times after being added with 1, determining whether the sleep duration is greater than the maximum value after being added with the set value;
if the sleep duration is determined to be greater than the maximum value after being increased by the set value, updating the sleep duration to the maximum value; and if the sleep time length is determined not to be larger than the maximum value after being increased by the set value, increasing the sleep time length by the set value.
The detection result is that no idle storage unit exists, so that whether the second continuous time plus 1 exceeds the set time or not needs to be determined, if the second continuous time plus 1 exceeds the set time, the first shared storage area does not have an idle storage space for multiple times, the sleep time needs to be increased to store information, the sleep time can be increased, at the moment, whether the sleep time is increased by the set value or not needs to be further determined, and is greater than the maximum value, specifically, if the sleep time is increased by the set value and is greater than the maximum value, the sleep time is updated to the maximum value; and if the sleep duration is determined to be not greater than the maximum value after being increased by the set value, increasing the sleep duration by the set value.
