Detailed Description
in order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first embodiment of the present invention, as shown in fig. 1, which is a schematic diagram of a method for controlling power consumption of a wireless signal receiving device according to a first embodiment of the present invention, the method includes the following steps:

and 2, after the power-on reset execution is successful, the wireless signal receiving equipment carries out the operation clock shutdown operation on the function execution unit.
And 3, the wireless signal receiving equipment performs digital signal conversion on the received wireless signal through the signal receiving unit to generate a first digital signal, wherein the first digital signal comprises a plurality of bit signals.
and 4, the wireless signal receiving equipment acquires the signal standard length from the system area to generate a first total length, acquires the synchronous signal standard length to generate a first synchronous length, acquires the minimum energy value of the synchronous signal to generate a first energy threshold, acquires the high-low level ratio of the synchronous signal to generate a first synchronous ratio, and acquires the minimum energy value of the bit signal to generate a second energy threshold.
step 5, the wireless signal receiving device carries out signal splitting processing on the first digital signal according to the first digital signal, the first total length and the first synchronous length to generate a first synchronous signal and a first code signal,
the method specifically comprises the following steps: step 51, the wireless signal receiving device generates a first code length according to the difference of the first total length minus the first synchronization length, and generates a first code start bit according to the sum of the value of the first code length plus 1;
Step 52, the wireless signal receiving device extracts continuous bit signals from the 1 st bit signal according to the first digital signal to generate a first synchronization signal, wherein the length of the first synchronization signal is specifically a first synchronization length;
And 53, the wireless signal receiving equipment extracts continuous bit signals from the bit corresponding to the initial bit of the first code to generate a first code signal according to the first digital signal, wherein the length of the first code signal is specifically the length of the first code.

The method specifically comprises the following steps: step 61, the wireless signal receiving device obtains the total number of bit signals of the first digital signal according to the first digital signal, and generates a first temporary total length;
In step 62, when the first temporary total length is equal to the first total length, the wireless signal receiving apparatus sets the first result as successful.
Here, the valid signal length check is a check for the length of the digital signal, and is a check for the basic integrity of the digital signal.
step 7, when the first result is successful, the wireless signal receiving device performs a first effective signal energy verification process on the first synchronous signal according to the first synchronous signal and a first energy threshold to generate a second result,
the method specifically comprises the following steps: step 71, the wireless signal receiving equipment performs signal energy calculation operation on the first synchronous signal according to the first synchronous signal in a digital signal energy calculation mode to generate first temporary energy;
and 72, when the first temporary energy is larger than or equal to the first energy threshold, the wireless signal receiving equipment sets the second result as successful.
here, the first valid signal energy check is performed to check whether the synchronization signal energy is up to standard. Generally, the synchronization signal of wireless communication is regularly switched between a continuous high level and a continuous low level, so the signal shape of the synchronization signal segment is fixed, and the energy should be relatively stable. The synchronization signal energy calculation here does not take the single bit signal calculation but the total energy calculation is performed for the entire synchronization signal.

Step 82, the wireless signal receiving equipment counts the total number of low level signals of the first synchronous signal according to the first synchronous signal to generate a first low level total number;
Step 83, the wireless signal receiving device performs ratio calculation operation on the total number of the first high levels and the total number of the first low levels to generate a first temporary high-low level ratio;
The wireless signal receiving device sets the third result as successful when the first temporary high-low level ratio is equal to the first synchronous ratio, step 84.
here, the active signal high-low level ratio verification is for synchronization signal integrity. In general, the synchronization signal of wireless communication is regularly switched between a continuous high level and a continuous low level. The high-to-low ratio of the sync signal segments is fixed. The high-low level ratio relation of the synchronous signal of the digital signal is checked to check the integrity of the synchronous signal.
step 9, when the third result is successful, the wireless signal receiving device performs a second effective signal energy check process on the first code signal according to the first code signal, the first total length, the first synchronization length and the second energy threshold to generate a fourth result,

Step 92, the wireless signal receiving device generates a first total number according to the difference obtained by subtracting the first synchronization length from the first total length;
Step 93, the wireless signal receiving device extracts a first index bit signal of the first code signal according to the first code signal to generate a first bit signal;
Step 94, the wireless signal receiving device performs signal energy calculation operation on the first bit signal according to the first bit signal in a digital signal energy calculation mode to generate first bit signal energy;
Step 95, when the energy of the first bit signal is greater than or equal to the second energy threshold, the wireless signal receiving device adds 1 to the value of the counter;
Step 96, the wireless signal receiving device adds 1 to the value of the first index;
Step 97, the wireless signal receiving apparatus determines whether the value of the first index is greater than the value of the first total number, and goes to step 98 if the value of the first index is greater than the value of the first total number, and goes to step 93 if the value of the first index is less than or equal to the value of the first total number;
the wireless signal receiving device sets the fourth result to be successful when the value of the counter equals the value of the first total number, step 98.
here, the second valid signal energy check is to perform signal energy check one by one for all bit signals of the code signal. The checking result is counted by using a counter, the counter passing the checking is added with 1, and the counter failing the checking is not added with 1. Therefore, if the energy of all bit signals of the code signal satisfies the minimum energy requirement, the value of the counter is necessarily equal to the total number of bit signals of the code signal, i.e. equal to the first total number.
and step 10, when the fourth result is successful, the wireless signal receiving equipment performs a working clock starting operation on the function execution unit to generate a fifth result.
the operation content of the step up to the step 12 is the operation content of the wireless signal receiving device to the function executing unit after the signal receiving unit confirms that the first digital signal is the valid signal. Generally, the signal receiving and processing unit has no task processing during the processing, and the wireless signal receiving device may enable the signal receiving and processing unit to synchronously receive the next wireless signal, which is determined by the software and hardware capabilities of the wireless signal receiving device.
and step 11, when the fifth result is successful, the wireless signal receiving device performs decoding execution operation on the first digital signal by using the function execution unit to generate a sixth result.
And step 12, when the sixth result is successful, the wireless signal receiving equipment performs the operation clock shutdown operation on the function execution unit.
