When the command code parameter is a switch command with the same code system, the code system parameter is the switch code system value. Therefore, in this manner, the wireless signal receiving device first determines whether the received digital signal is of the current valid signal specification (first data set parameter), if so, decodes the code signal to obtain a decoded code, and determines whether the decoded code is a code switching instruction, if so, extracts the code parameter to generate a switching code value, and queries a code parameter record file storing the signal specification data to obtain a whole set of signal specification data to generate a new code signal data set and resets the current code signal data set in the system, thereby completing the code switching operation.

And 105, the wireless signal receiving equipment acquires the signal length of the first digital signal according to the first digital signal to generate a first digital signal length.
In step 106, the wireless signal receiving apparatus determines whether the first digital signal length is equal to the first signal length, and goes to step 107 if the first digital signal length is equal to the first signal length, or goes to step 115 if the first digital signal length is not equal to the first signal length.
Step 107, the wireless signal receiving device determines whether the first status word is equal to the same-code system instruction switching mode, if the first status word is equal to the same-code system instruction switching mode, the step 108 is proceeded, and if the first status word is not equal to the same-code system instruction switching mode, the step 370 is proceeded to perform other signaling processing flow of the current code system;
Step 111, the wireless signal receiving device obtains the same code system switching instruction from the system area to generate a first instruction.

Step 380, the wireless signal receiving device processes the first digital signal according to the common signaling under the current code system.
In general, the step 370 or 380 is performed in a same-code-system instruction switching manner, and it is found that the currently received same-code-system signal is not a process caused by a code-system switching instruction.
In step 410, the digital signal synchronization signal is in error, and the wireless signal receiving device exits the process flow of the digital signal.
Here, the error typically results because the received wireless signal format does not conform to the signal characteristics of the signal code system currently considered legitimate.
The invention provides a multi-code system signal switching method, which supports two code system switching modes: the switching mode of different code system instruction or the switching mode of the same code system instruction.
When the different-code system instruction switching mode is adopted, the instruction signal for completing code system switching and the currently identified effective signal do not adopt the same signal specification: the total lengths of the signals are different, the lengths of the synchronous signals are different, the high-low level ratios of the synchronous signals are different, and the value contained in the code signal is the switching code system value. Therefore, in this manner, the wireless signal receiving device first determines whether the received digital signal is the current valid signal specification (first data set parameter), if not, it needs to determine whether the received digital signal is the command signal specification (second data set parameter) for code system switching, if the received digital signal is the code system switching command specification, the wireless signal receiving device decodes the code signal to obtain the switching code system value, and queries the code system parameter record file storing the signal specification data to obtain the whole set of signal specification data to generate a new code system signal data set and resets the current code system signal data set in the system, thereby completing the code system switching operation.
When the same code system instruction switching mode is adopted, the instruction signal for completing code system switching and the currently identified effective signal adopt the same signal specification: the total length of the signals is the same, the lengths of the synchronous signals are the same, the high-low level ratios of the synchronous signals are the same, the numerical value contained in the code signal is a proprietary code system switching instruction, and the instruction comprises two parameters: instruction code parameters and code system parameters. When the command code parameter is a switch command with the same code system, the code system parameter is the switch code system value. Therefore, in this manner, the wireless signal receiving device first determines whether the received digital signal is of the current valid signal specification (first data set parameter), if so, decodes the code signal to obtain a decoded code, and determines whether the decoded code is a code switching instruction, if so, extracts the code parameter to generate a switching code value, and queries a code parameter record file storing the signal specification data to obtain a whole set of signal specification data to generate a new code signal data set and resets the current code signal data set in the system, thereby completing the code switching operation.
By using the method of the invention, the flexible support of the single wireless signal receiving device to the multi-code system is realized, the redundancy requirement of the wireless signal receiving device in practical application is reduced, and the hardware upgrading and maintenance cost of an application system is reduced.
