Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to illustrate the technical scheme of the application, the following description is made by specific examples.
As described in the background art, at present, a serial port chip can only be suitable for one protocol, and although the internal program of the serial port chip can be modified to change the adapting protocol of the serial port chip, the mode needs to rely on technicians, so that the time is long, errors are easy to occur, and the problem of complex operation exists.
In order to solve the problems in the prior art, the embodiment of the application provides a serial port communication method and a serial port chip based on a test mode. The serial communication method based on the test mode provided by the embodiment of the application is first described below.
The execution main body of the serial communication method based on the verification mode can be a serial chip, such as a digital signal processing (Digital Signal Processing, DSP) chip, a field programmable gate array (Field Programmable Gate Array, FPGA) chip and the like, and the serial chip can be externally connected with hardware, such as a charging module of an electric automobile, a power module of a charging pile, a monitoring device and the like. In addition, the serial port chip can be a multi-serial port chip or a single serial port chip.
As shown in fig. 1, the serial port communication method based on the inspection mode provided by the embodiment of the application may include the following steps:
step S110, receiving target data;
in some embodiments, the target data may be any data received by the serial chip.
And step S120, checking the target data according to a preset checking mode array.
The preset verification mode array comprises a plurality of verification modes, wherein each verification mode uniquely corresponds to a protocol object which is constructed in advance based on an object-oriented principle;
in some embodiments, the verification manner may be a manner of verifying the data based on a value of a specific location in the data, such as a function code, a data length, etc., for example, whether the function code and the data length in the data frame are the same as the preset values. It should be noted that when the function code and the data length are different, that is, the verification sequence of the objects to be verified is different, the verification modes are also different.
In some embodiments, a preset check mode array and a preset protocol array may be preconfigured, and elements in the preset check mode array and the preset protocol array may be associated, where the preset protocol array may record protocol objects associated with each check mode. Then, the target data can be checked by sequentially adopting a check mode in a preset check mode array; and when the verification is passed, recording the verification mode adopted at the present time, and stopping the verification.
Optionally, the serial port chip may increase the verification mode in the preset verification mode array based on the input verification mode registration request, so as to expand the protocol application range of the serial port chip, and the corresponding processing may be as follows: receiving a verification mode registration request for a target verification mode; and adding the target verification mode to a preset verification mode array.
The verification mode registration request carries a target verification mode and a protocol object corresponding to the target verification mode;
in some embodiments, the serial port chip may further modify or delete the verification mode in the preset verification mode array based on the input verification mode modification request, so as to update the protocol application range of the serial port chip.
Step S130, when the target data passes the verification, the target data is sent to a protocol object corresponding to the verification mode adopted when the verification passes.
In some embodiments, when the target data passes the verification, it indicates that the protocol object corresponding to the target data is already built in the internal program of the serial port chip in advance, so that the target data can be sent to the protocol object corresponding to the target frame header to call the protocol object corresponding to the target data to process the target data, thereby realizing the communication between the serial port chip and the external device.
Optionally, the embodiment of the application provides a serial port chip for realizing a serial port communication method based on a verification mode, wherein the serial port chip comprises at least one serial port, a bottom layer configuration module and a protocol verification module;
specifically, after the bottom layer configuration module acquires the target data of the target serial port, a target bottom layer object corresponding to the target serial port can be determined in a plurality of bottom layer objects, so that the target bottom layer object sends the target data to the protocol verification module; the method comprises the steps that a bottom object is constructed and obtained in advance based on an object-oriented principle, each bottom object uniquely corresponds to one serial port, and serial ports corresponding to each bottom object are different; and the protocol verification module receives the target data and verifies the target data according to a preset verification mode array.
Optionally, the serial port chip capable of implementing the serial port communication method based on the verification mode may further include a protocol analysis module. Correspondingly, the protocol analysis module sends the target data and the verification information to the protocol analysis module; the protocol analysis module can send the target data to the protocol object corresponding to the verification mode adopted when the verification passes according to the protocol object corresponding to the verification mode adopted when the verification passes, which is carried in the verification information.
In order to better understand the serial communication method based on the frame header provided by the embodiment of the application, the following description is made.
For a single serial port chip, considering that the single serial port chip can only be suitable for a single baud rate at each time, namely, the baud rate is fixed during each communication, however, different protocols can exist under the fixed baud rate, and for the situation, the serial port communication method based on the verification mode provided by the embodiment of the application can be utilized for distinguishing. For a multi-serial port chip, any serial port number can be regarded as a single serial port chip.
As shown in fig. 2 and fig. 3, an architecture diagram and a signal flow diagram of a serial port chip are shown respectively, based on the architecture, protocols requiring different verification modes for different manufacturers can be used for solving the protocol layer coupling problem of different chips by using a protocol verification module no matter aiming at a single serial port chip or a multi-serial port chip, so as to realize decoupling of protocol layers.
Specifically, for the data receiving process, the signal of the bottom layer configuration module may carry information such as a serial number, a data length, a buffer area first address, etc. and be connected with the slot of the protocol allocation module, and the protocol verification module performs protocol allocation on the received data according to different verification modes, and allocates the received data to a protocol object corresponding to the protocol layer. And for the data transmission process, the signals of the protocol layer are connected with the grooves of the bottom layer configuration module, and the data to be transmitted are directly transmitted to the bottom layer configuration module for transmission.
It should be noted that, in order to improve the efficiency of protocol verification, the frame header may be utilized to group the verification modes in the preset verification mode array in advance, that is, one frame header may correspond to one or more verification modes that are adapted. After receiving the target data, the corresponding verification mode group can be determined according to the frame header of the target data, and then the target data is verified in sequence by utilizing the verification modes included in the verification mode group, so that the verification process of the verification mode which obviously does not accord with the specific frame header can be reduced, and the efficiency of protocol verification is improved.
As shown in fig. 4, a protocol verification process is shown, which is specifically as follows:
1. and searching the registered frame header by using a dichotomy, namely reading data in a buffer area, comparing the data with the frame header positioned in the middle of the preset frame header group, and searching downwards from the position if the data is larger than the frame header value, otherwise, searching upwards.
2. When the frame head consistent with the data in the reading buffer area is found, the data is checked by calling the check mode in the check mode grouping corresponding to the frame head, and when the check is passed, the data is sent to the protocol object corresponding to the check mode adopted when the check is passed.
In addition, whether the verification passes or fails, the final read index value needs to be recorded so as to continuously judge the data in the receiving buffer area from the position of the read index value next time. In the whole verification process, all data in the receiving buffer area need to be traversed and verified.
As shown in fig. 5, a serial communication architecture employing the frame header feature is shown. For the protocol layer, the protocol checking process and the subsequent data processing process are required to be separated, and different protocols are established according to different checking modes to perform decoupling. The protocol layer protocol verification process may be as follows:
1. if the verification is correct, the final reading index value is returned, and if the verification is wrong, 0 is returned.
2. And (3) temporarily placing all valid data except invalid data such as frame heads so as to perform data processing.
It should be noted that, a multi-serial communication architecture can be designed based on an object-oriented method, such as c++, and the architecture has the following functions:
and the function 1 uses a protocol verification module, and the module is positioned in front of the protocol analysis module and distributes data according to different verification modes and transmits the data to the protocol analysis module.
And 2, a protocol analysis module specifically analyzes protocol content, creates different protocols according to different verification modes, realizes one-to-one correspondence of frame heads and protocols, and solves the problem of strong coupling of protocol layers.
The function 3 and the signal slot mechanism are applied to a serial port communication architecture, and all modules are mutually decoupled and do not interfere with each other.
Therefore, the problem of protocol coupling of the protocol layer can be solved, and the protocol decoupling of the protocol layer is realized, so that after the serial port chip receives data, a protocol object of the protocol can be called for processing after the corresponding protocol is found.
In the embodiment of the application, after receiving the target data, the target data can be checked according to a preset check mode array; the preset check mode array comprises a plurality of check modes, and each check mode uniquely corresponds to one protocol object which is constructed in advance based on an object-oriented principle. And under the condition that the target data passes the verification, sending the target data to a protocol object corresponding to a verification mode adopted when the verification passes. Therefore, the serial port chip can be internally provided with a plurality of protocols, can decouple the protocols, can automatically find the protocol corresponding to the data based on the verification mode in the preset verification mode array, can adapt to the plurality of protocols without modifying an internal program by a technician, and is convenient to operate.
