Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a data processing method and a base station device.
Background
The baud rate, i.e. the modulation rate, refers to the number of baud in a unit time after the signal is modulated, i.e. the number of times the carrier parameter changes in the unit time.
In asynchronous serial communication, communication can be performed normally only when the baud rates of both parties of communication are identical. Therefore, before communication, both the communication parties need to set respective baud rates. Meanwhile, in the communication process, when one of the two communication parties changes the baud rate, the other of the two communication parties needs to perform baud rate self-adaptive operation, namely baud rate synchronization.
However, in practical applications, when the communication between the two parties is abnormal, the baud rates of the two parties may be different, or the baud rates may be caused by external signal interference. If the two communication parties are not in normal communication, the program enters baud rate self-adaptive operation, and the robustness problem of the program is caused. The robustness of the program means that the program can judge that the input does not meet the specification requirement for the input except the specification requirement, and a reasonable processing mode can be provided.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and 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.
The terms "first," "second," "third," and "fourth," if any, in the description and claims of the invention and the above-described figures are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1, fig. 1 is a flowchart of an embodiment of a data processing method according to the present invention, the method including:
101. the method comprises the steps that first base station equipment receives first data sent by second base station equipment;
the second base station may be a master base station device, the first base station device may be a slave base station device of the master base station device, and the first data may be one of the master base station device transmitting periodic inquiry frames to the slave base station device. In the normal communication process, the master base station device periodically sends an inquiry frame to each slave base station device to inquire the state of each slave base station device. The slave base station device can calculate the baud rate of the master base station device according to the special data (such as data segments of '010' or '101') in the query frame, so as to set the baud rate of the slave base station device to be consistent with the baud rate of the master base station device, namely baud rate self-adaption, also called baud rate synchronization.
It should be understood that, in terms of baud rate adaptation, the master base station device does not need to additionally add any operation related to baud rate adaptation, and only needs to add a baud rate adaptation function module to the slave base station device to implement baud rate adaptation between the slave base station device and the master base station device. The baud rate adaptive function module may specifically include the following functions:
1) after the system is powered on, the baud rates of the slave base station equipment and the master base station equipment are self-adaptive;
2) when the baud rate of the main base station equipment is changed, the slave base station equipment automatically detects the change of the baud rate of the main base station equipment and automatically synchronizes to the baud rate after the change of the main base station equipment;
3) and when the master base station equipment is replaced (namely the slave base station equipment is replaced to new master base station equipment), the slave base station equipment can carry out self-adaptation according to the baud rate of the new master base station equipment.
The slave base station device may receive the query frame periodically transmitted by the master base station device by using a General Purpose Input/Output (GPIO) of a single chip.
102. The first base station equipment analyzes whether the first data has transmission errors; if yes, go to step 103; if not, go to step 104;
the transmission error may include: at least one of a noise error, a parity error, a frame error, and a Cyclic Redundancy Check (CRC) check error. That is, the transmission error may be one of the foregoing errors, or may be multiple of the foregoing errors, and is not limited herein.
When the slave base station device analyzes whether the query frame has a transmission error, it may analyze whether there are the above errors one by one.
It should be noted that, the method for detecting whether there is a transmission error in the query frame is described in detail in the prior art, and for brevity of writing, the description is omitted here.
For example: the slave base station device may analyze whether the query frame has a noise error, if yes, execute step 103, if no, analyze whether the query frame has a parity error, and so on.
When the slave base station device analyzes the transmission errors one by one, the analysis sequence of the transmission errors is not limited herein.
103. The first base station apparatus adds 1 to the value of the counter;
and when the slave base station equipment analyzes whether each periodic inquiry frame has transmission errors, adding 1 to the value of the counter every time the transmission errors occur.
104. The first base station apparatus changes the value of the counter to a default value and processes the first data.
When the slave base station equipment resolves that the query frame has no transmission error, the slave base station equipment normally processes the first data, which shows that the query frame is not interfered by signals during transmission and the problem that the baud rates of the slave base station equipment and the master base station equipment are inconsistent does not occur.
105. The first base station equipment judges whether the value of the counter is greater than a preset value; if yes, go to step 107, otherwise go to step 106;
the initial value of the counter may be 0 or other values, and the slave base station device, after adding 1 to the value of the counter, correspondingly determines whether the value of the counter exceeds 1, and if so, indicates that the transmission error of the query frame exceeds one time. In the data transmission process, if the periodic query frame has a transmission error for the first time, the transmission error will continue to occur for the next time. It is indicated that the query frame may be caused by the fact that the baud rates of the slave base station device and the master base station device are not consistent, so that the query frame is repeatedly transmitted, because signal interference may cause the query frame to be transmitted incorrectly for the first time, and because signal interference is eliminated or weakened for the second time or more, the query frame is not transmitted incorrectly.
Optionally, if the query frame is interfered by a signal, the slave base station device may also cause the query frame to have more than one repeated transmission error, and then the slave base station device may determine whether the value of the counter is greater than a preset value, that is, the number of times of the transmission errors of the query frame continuously reaches the preset value or more. That is, as long as the number of times that the program does not generate transmission errors does not continuously reach the preset value, the program will not jump to the baud rate synchronization PRE-IDLE state (PRE-IDLE: a self-defined state machine name designed to perform baud rate adaptive operation in this state).
The embodiment of the invention records the times of transmission errors through the counter, jumps into the mode of the PRE-IDLE state machine when the counter reaches a preset value (for example, the value of the counter is 5, or other values), effectively improves the readability and the robustness of the program, solves the problem that the baud rate is different due to signal interference when judging errors through differential processing of different types of exceptions of the serial port, improves the practicability of the program, and can ensure the robustness and the practicability of the program by utilizing a state machine processing mechanism and a special exception processing mechanism.
106. The first base station equipment receives second data sent by the second base station equipment;
if the value of the counter is not greater than the preset value, the slave base station equipment continues to receive the periodic query frame, and then performs analysis of the transmission error, that is, returns to execute step 102, and so on.
107. Carrying out baud rate synchronization operation by the first base station equipment;
in this embodiment, after a plurality of transmission errors occur in the query frame, it is determined that the baud rates of the slave base station device and the master base station device may be inconsistent, and at this time, baud rate synchronization operation of the slave base station device is performed.
In practical applications, the baud rate is usually divided into several steps, which may range from 1200bps to 10Mbps, such as: 1200bps, 2400bps, 4800bps, 9600bps, 14400bps, 19200bps, 38400bps, 56000bps, 57600bps, 115200bps, 230400bps, 460800bps, 921600bps, etc.
When the slave base station equipment performs baud rate synchronous operation, the baud rates at two communication ends are manually set in the prior art, the mode has low efficiency and is troublesome to operate, and particularly when only one baud rate is known but the other baud rate is not known, the slave base station equipment needs to try or use an oscilloscope for measurement for many times.
Of course, in the prior art, the baud rate of the main base station device is detected first, and then baud rate synchronization operation is performed. There are many methods in the prior art for detecting baud rate, including hardware methods and software methods. The hardware method includes a counter-based detection method and a phase-locked loop-based detection method, and the software method includes a table look-up method, a calculation method and the like.
However, although the hardware method has a fast detection speed, it needs to occupy additional hardware resources. Although there are many solutions to the software method, these solutions only solve the problem of adaptation in principle, and are still not enough in the robustness of the program, and the practicability is low.
Referring to fig. 2, fig. 2 is a flowchart of an embodiment of baud rate synchronization operation according to the present invention, including:
201. the method comprises the steps that first base station equipment acquires a first group of data, wherein the first group of data comprises at least one piece of data;
after confirming that the baud rates of the slave base station equipment and the master base station equipment are inconsistent, the slave base station equipment continues to receive periodic query frames through the GPIO and receives a plurality of query frames, so that the accuracy of the slave base station equipment in calculating the baud rate of the master base station equipment is improved.
202. When the first base station equipment detects that a first data segment with high level and low level changes exists in the first group of data, at least one first interval time from the first high/low level to the first low/high level and from the first low/high level to the second high/low level in each time of the first data segment is recorded;
in the process of calculating the baud rate of the master base station equipment, the slave base station equipment needs to acquire a first interval time of changing a 010 data segment from a low level to a high level and then to the low level or a first interval time of changing a 101 data segment from the high level to the low level and then to the high level in an inquiry frame through a timer.
203. The first base station equipment determines the first interval time with the shortest time in all the first interval times as the shortest first interval time;
since there are data segments such as "1001" and "10001" in addition to the data segment of "010" or "101" in the query frame, and the first interval time of the high-low level change of the data segment of "010" or "101" is the shortest, it is necessary to extract the first interval time with the shortest time and determine the first interval time as the shortest first interval time.
In order to ensure that the slave base station device can obtain the first interval time of the high-low level change of the data segment of "010" or "101", the above steps 201 to 203 may be repeated 20 times, continuously collect the first interval time of the high-low level change of the data segment in the query frame, and make the judgment on the shortest first interval time.
204. When the first base station equipment detects that a second data segment with high level and low level changes exists in the second group of data, at least one second interval time of each change from the first high/low level to the first low/high level and then from the first low/high level to the second high/low level in the second data segment is recorded;
after determining the shortest first interval time of the high-low level change of the data segment in the query frame, the slave base station device may further receive a second set of data again, where the second set of data includes at least one data, and may further collect a second interval time of the high-low level change of the data segment in the query frame.
It should be noted that the first base station device may receive at least one piece of data again, or may use at least one piece of data received before, which is not limited herein.
205. The first base station equipment judges whether a second interval time which is less than twice the shortest first interval time exists in all the second interval times; if yes, go to step 206, otherwise go to step 207;
the slave base station apparatus may compare the second interval time of the high-low level change of the data segment in the query frame acquired in step 204 with the shortest first interval time determined in step 203, determine whether the second interval time in step 205 is less than twice the shortest first interval time, if yes, perform step 206, and if not, perform step 207.
206. The first base station equipment calculates the average value of all the second interval time which is less than twice the shortest first interval time, and obtains the baud rate of the second base station equipment through the average value calculation;
the slave base station apparatus calculates the baud rate of the master base station apparatus by averaging all the second interval times smaller than twice the shortest first interval time in step 205.
It should be noted that, after the average value of all the second interval times is calculated, the time required for receiving one bit of character can be obtained by dividing the average value time by the number of bits of the received character in the average value time, and then the baud rate of the main base station device can be obtained by calculating how many bits of character can be received in 1 second.
In order to improve the accuracy of calculating the baud rate of the main base station device, the above steps 204 and 205 may be repeated 40 times, the second interval time of the high-low level change of the data segment in the query frame is continuously collected, and the judgment is performed on the first interval time which is less than twice as short as the first interval time.
207, step 204 is re-executed.
When it is determined that the second interval time in step 205 is not less than twice the shortest first interval time, step 204 is re-executed until it is determined that there is a second interval time in the second interval time that is less than twice the shortest first interval time.
208. And the first base station equipment carries out baud rate synchronization according to the baud rate of the second base station equipment.
After the baud rate of the main base station equipment is calculated, the slave base station equipment can perform baud rate synchronization, so that the baud rates of the slave base station equipment and the main base station equipment are consistent.
After the baud rate is synchronized, the slave base station equipment feeds back the state information of the slave base station equipment to the master base station equipment, and if the master base station equipment receives the reply of the slave base station equipment, the success of communication is indicated. If the baud rate of the main base station equipment is changed in the middle of communication or the slave base station equipment is replaced to new main base station equipment, the communication fails, and the program also enters a PRE-IDLE state.
The embodiment of the invention measures the time for sending a symbol in the periodic query frame sent by the main base station equipment to each slave base station equipment by using the GPIO and the timer, and calculates the baud rate of actual communication by adopting a method of measuring and averaging multiple groups of measured data, thereby achieving the purpose of baud rate self-adaption, improving the usability of products and simplifying the operation. The measurement accuracy of the baud rate is improved by an innovative method of averaging.
Meanwhile, the embodiment of the invention utilizes the inquiry frame of the slave base station equipment which is periodically sent to the slave base station equipment by the main base station equipment, thereby realizing the synchronization without the training sequence.
In addition, the embodiment of the invention can be used for baud rate synchronization in serial communication and can also be applied to other occasions requiring baud rate self-adaptation, and the embodiment of the invention is not limited in the details.
Referring to fig. 3, fig. 3 is a flowchart of another embodiment of baud rate synchronization operation according to the present invention, including:
301. the method comprises the steps that first base station equipment acquires a first group of data, wherein the first group of data comprises at least one piece of data;
302. when the first base station equipment detects that a first data segment with high level and low level changes exists in the first group of data, at least one first interval time from the first high/low level to the first low/high level and from the first low/high level to the second high/low level in each time of the first data segment is recorded;
303. the first base station equipment determines the first interval time with the shortest time in all the first interval times as the shortest first interval time;
it should be noted that steps 301 to 303 are similar to steps 201 to 203 in fig. 2, and detailed description is given above, which is not repeated herein.
304. The first base station equipment calculates the baud rate of the second base station equipment through the shortest first interval time;
in this embodiment, after the first base station device determines the shortest first interval time, the number of bits of the received character in the shortest interval time may be divided by the shortest interval time, so as to obtain the amount of time required for receiving one bit of the character, and then, the number of bits of the received character in 1 second may be calculated, so as to obtain the baud rate of the second base station device.
305. The first base station equipment carries out baud rate synchronization according to the baud rate of the second base station equipment
It should be noted that step 305 is similar to step 307 described in fig. 2, and the above description has been already made in detail, and is not repeated here.
Compared with the prior art, the embodiment of the invention has the following advantages:
1) the installation, the test and the maintenance are convenient: compared with the mode of manually setting the baud rate in the prior art, the baud rate self-adaption technology of the embodiment of the invention effectively reduces manual configuration operation, reduces the possibility of configuration error and improves the efficiency;
