Please refer to fig. 2, which is a flowchart illustrating a method for reporting sensor data according to a first embodiment of the present invention, the method includes:
step 201, monitoring a plurality of sensors, intercepting sensor data when monitoring that the sensors report the sensor data, and caching the sensor data into a preset cache region;
in the embodiment of the present invention, a plurality of applications with different functions may be installed on the mobile terminal, and in order to implement the functions of the applications, the mobile terminal includes a plurality of sensors with different types, and after the applications are started or when a certain specified function is executed, the data of the sensors needs to be called, so as to implement the corresponding function.
The method for reporting sensor data is specifically realized by a sensor data reporting device (hereinafter referred to as reporting device), which may be a mobile terminal or a part of components in the mobile terminal.
In the embodiment of the invention, when the application program needs to use the data of the sensor, the calling instruction of the sensor is generated and sent to the sensor, and after the sensor receives the calling instruction, the sensor data is generated and reported.
In the embodiment of the invention, the reporting device monitors a plurality of sensors, wherein the plurality of sensors refer to all sensors in the mobile terminal, and when the sensors are monitored to report sensor data, the sensor data are intercepted and cached in a preset cache region.
and step 203, reporting the packed data.
In the embodiment of the present invention, the reporting device determines whether the sensor data cached in the cache area needs to be packed, specifically: the reporting device determines whether the group number or the data size of the sensor data cached in the cache region is greater than or equal to a corresponding preset value within a preset time period.
The sensor data generated and reported by each sensor can be referred to as a group of sensor data, that is, the sensor data reported by the sensors is reported in units of groups.
In the embodiment of the present invention, in a preset time period, if the number of groups of sensor data cached in the cache region is greater than or equal to the preset number of groups, or the size of the data is greater than or equal to the preset size, in this case, the reporting device packages the sensor data in the cache region according to the number of bits of the preset type of shaped data to obtain packaged data, and reports the packaged data.
The shaping data may specifically be int shaping data, and the number of bits of the int shaping data is 32 bits.
It should be noted that the int shaping data is mainly used in consideration that many current ARM systems are 32 bits, that is, if the sensor data is reported in the form of int shaping data, the maximum is supported by the power of 32 of 2, the sensor data of the commonly used sensors are small, but 16 bits are needed at most, and 8 bits or even 2 bits are needed, so that if reporting is carried out by taking a group of sensor data as a unit, based on the point that a plurality of groups of sensor data or sensor data with the data size meeting the condition in the cache region are packed, each bit in the 32-bit data format can be fully used, the data reporting times can be reduced, the data size reported by the data can be reduced, and the resource occupation can be further reduced.
In the embodiment of the invention, a plurality of sensors are monitored, when the sensors report sensor data, the sensor data are intercepted and cached in a preset cache region, and if the group number or the data size of the sensor data cached in the cache region is larger than or equal to a corresponding preset number value in a preset time period, the sensor data cached in the cache region are packaged according to the digit of preset type shaping data to obtain packaged data, and the packaged data are reported. Compared with the prior art, the sensor data are intercepted and cached in the cache region, and all the sensor data in the cache region are packaged, so that all the cached sensor data can be packaged and reported when being reported every time, each group of sensor data of the sensors is prevented from being reported, the reporting times are reduced, the resource consumption is reduced, and the system load is reduced.
Please refer to fig. 3, which is a flowchart illustrating a method for reporting sensor data according to a second embodiment of the present invention, the method includes:
step 301, monitoring a plurality of sensors, intercepting sensor data when monitoring that the sensors report the sensor data, and caching the sensor data into a preset cache region;
in the embodiment of the present invention, the content of step 302 is similar to that described in step 201 of the first embodiment, and is not described herein again.
303, when a preset time period is reached, if the group number or the data size of the sensors cached in the cache region is smaller than a corresponding preset number value, packaging the sensor data in the cache region according to the digit of the preset type of shaping data to obtain packaged data;
and step 304, reporting the packed data.
In the embodiment of the present invention, the preset time period is determined based on the timestamp included in the sensor data cached in the cache region, and the preset time period is a time period formed by taking the timestamp included in the sensor data cached earliest in the cache region as a starting point and a preset time period, that is, the preset time period is counted from the timestamp included in the sensor data cached earliest, for example, if A, B, C sets of sensor data are cached in the cache region, the preset time period is 5ms, and the timestamp of the sensor data of the group a is earliest, the sensor data in the cache region is counted by the timestamp of the sensor data of the group a, and the sensor data in the cache region is packed after 5 ms. It can be understood that by setting the preset time period and setting the preset time period with the timestamp included in the sensor data cached earliest in the cache region as the starting point, the sensor data in the cache region can be effectively prevented from being unreported for too long time, which brings influence on the application program function needing to use the sensor data, so that the sensor data can be packaged and reported on the basis of ensuring the reporting speed.
The reporting device monitors whether a preset time period is reached in real time, determines whether the group number or the data size of the sensor data cached in the cache region is larger than or equal to a corresponding preset value when the preset time period is not reached, and packages the sensor data in the cache region according to the digit of the preset type of shaping data to obtain packaged data under the condition that the group number or the data size of the sensor data cached in the cache region is larger than or equal to the corresponding preset value, or packages the sensor data in the cache region according to the digit of the preset type of shaping data to obtain packaged data when the preset time period is reached and if the group number or the data size of the sensor data cached in the cache region is smaller than the corresponding preset value.
The method includes the steps of packing sensor data in the cache region according to the number of bits of preset type shaping data to obtain packed data, and specifically includes the following steps: the reporting device determines the number of bits required to be used by the sensor data in the buffer area, for example, if 3 sets of sensor data are buffered in the buffer area, the number of bits required to be used by the 3 sets of sensor data are determined respectively. And after the number of bits required to be used by each group of sensor data is determined, combining the number of bits required to be used by each group of sensor data into at least one group of packed data in a 32-bit shaped data format by taking a group of packed data as a standard.
It will be appreciated that in combining sensor data, to distinguish between different data sets, a flag may be set that identifies all data preceding the next flag as belonging to the same sensor data. When multiple sets of sensor data are arranged, the flag bit, the sensor data, the identification bit, the sensor data, the flag bit, and the sensor data may be packed in sequence. The sensor data includes sensing data, a timestamp, and a sensor type. And each group of sensor data is arranged according to the sequence of the sensor type, the time stamp and the induction data when being packed.
In the embodiment of the invention, by intercepting the sensor data and caching the sensor data in the cache region and packaging all the sensor data in the cache region, all the cached sensor data can be packaged and reported each time of reporting, so that each group of sensor data of the sensors is prevented from being reported, the reporting times are reduced, the resource consumption is reduced, and the system load is reduced.
