Abstract

A method and a terminal for reporting sensor data are provided. The method for reporting sensor data includes: when a processor needs to process only sensor data collected by a sensor, sending, by the processor, an indication that the processor is to enter a sleep state, and entering the sleep state; after the processor enters the sleep state, receiving and temporarily storing, by a sensor hub, the sensor data collected and reported by the sensor into an event information table, recording, by the sensor hub, corresponding time at which the sensor collects the sensor data, and further temporarily storing the time into the event information table; and when the processor is restored to a working state, reporting, by the sensor hub, the event information table to the processor, so that the processor parses the event information table to complete corresponding processing.

22 . A method for reporting sensor data, the method comprising:
when a processor determines that only sensor data collected by a sensor needs to be processed currently, sending, by the processor, indication information indicating that the processor is to enter a sleep state, and entering the sleep state, wherein the indication information is used to enable a sensor hub to receive and temporarily store, after receiving the indication information, the sensor data collected by the sensor; and when the processor is restored to a working state, sending indication information indicating that the processor is restored to the working state, wherein the indication information is used to enable the sensor hub to report the temporarily stored sensor data to the processor after receiving the indication information.

23 . The method according to claim 22 , wherein:
receiving and temporarily storing the sensor data collected by the sensor comprises:
receiving and temporarily storing the sensor data collected by the sensor into an event information table, recording corresponding time at which the sensor collects the sensor data, and further temporarily storing the time into the event information table; and
reporting the sensor data to the processor comprises:
reporting the event information table to the processor.

24 . The method according to claim 23 , wherein that the processor determines that only the sensor data collected by the sensor needs to be processed currently comprises:
identifying identification information of an interaction party interacting with the processor, and when the identified identification information comprises only identification information of the sensor, determining, by the processor, that only the sensor data collected by the sensor needs to be processed currently.

25 . The method according to claim 22 , wherein entering, by the processor, the sleep state comprises:
disconnecting a clock and a power source of the processor.

26 . The method according to claim 22 , wherein that the processor is restored to the working state comprises:
customizing a condition under which the sensor hub wakens the processor, and when the sensor hub determines that the wakening condition is met, wakening the processor, and wherein the condition comprises at least one of the following:
an amount of data in the event information table exceeds a specific value; and
duration in which the processor is in the sleep state exceeds a specific value.

27 . The method according to claim 23 , wherein the method further comprises:
receiving and parsing, by the processor, the event information table reported by the sensor hub, so as to obtain the sensor data and a set of the corresponding time at which the sensor collects the sensor data.

28 . The method according to claim 23 , wherein the method further comprises:
receiving and parsing, by the processor, the event information table reported by the sensor hub, so as to acquire the sensor data and record time at which the sensor data is acquired, wherein the time is acquiring time; and calculating, according to the acquiring time in a manner of time mapping, the corresponding time at which the sensor collects the sensor data.

29 . The method according to claim 28 , wherein when the event information table is an event queue, the manner of time mapping comprises the following:
the working state of the processor comprises a compression working state, and in the compression working state, the processor needs to acquire sensor data that is temporarily stored by the sensor hub when the processor is in the sleep state and the compression working state; the processor calculates sleep duration T 1 from time at which the processor enters the sleep state to time at which the processor enters the compression working state, wherein a starting moment at which the processor enters the sleep state is T 10 ; the processor calculates duration T 2 from the time at which the processor enters the compression working state to time at which the compression working state ends, wherein a starting moment at which the processor enters the compression working state is T 20 ; and the processor adjusts a system time interface, so that when the processor acquires sensor data at acquiring time T 20 +τ, corresponding time that is read by the system time interface and at which the sensor collects the sensor data is T 10 +τ*(T 1 +T 2 )/T 2 , wherein ti indicates a duration variable starting from the compression working state, and when τ is the largest, the compression working state ends (0≦τ≦T 2 ).

30 . A terminal, comprising:
a sensor configured to collect sensor data; a processor configured to:
when it is determined that only the sensor data collected by the sensor needs to be processed currently, send indication information indicating that the processor is to enter a sleep state, and enter the sleep state, and
when the processor is restored to a working state, send indication information indicating that the processor is restored to the working state, and receive the sensor data reported by a sensor hub; and
wherein the sensor hub is connected between the sensor and the processor, and is configured to:
after receiving the indication indicating that the processor is to enter the sleep state, receive and temporarily store the sensor data collected by the sensor, and after receiving the indication indicating that the processor is restored to the working state, report the sensor data to the processor.

31 . The terminal according to claim 30 , wherein the sensor hub is further configured to:
receive and temporarily store the sensor data collected by the sensor into an event information table, record corresponding time at which the sensor collects the sensor data, and further temporarily store the time into the event information table; and report the event information table to the processor.

32 . The terminal according to claim 31 , wherein the sensor hub further comprises:
a determining unit, configured to check whether a wakening condition of the processor is met, and if the wakening condition is met, waken the processor, so that the processor is restored from the sleep state to the working state, wherein the wakening condition comprises at least one of the following: an amount of data temporarily stored in the event information table exceeds a specific value; and duration in which the processor is in the sleep state exceeds a specific value.

33 . The terminal according to claim 31 , wherein the processor comprises:
a receiving unit, configured to receive the sensor data reported by the sensor hub; and a processing unit, configured to parse the sensor data received by the receiving unit.

34 . The terminal according to claim 33 , wherein the processing unit is configured to:
parse out the sensor data and a set of the corresponding time at which the sensor collects the sensor data, and process the sensor data.

35 . The terminal according to claim 33 , wherein:
the processing unit is configured to:
parse out the sensor data and record time at which the sensor data is acquired, wherein the time is acquiring time; and
the processor is configured to:
calculate, according to the acquiring time in a manner of time mapping, the corresponding time at which the sensor collects the sensor data.
