Fig. 1 is a flowchart of a general method for analyzing sensor data according to a first embodiment of the present invention.
Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a general analysis method and a general analysis system for sensor data.
As shown in fig. 1, in a first embodiment of a general parsing method for sensor data according to the present invention, the general parsing method is applied to a general parsing system for sensor data, where the system includes a host, a storage device (preferably a hard disk), a display device (preferably a display), and a plurality of sensors; the storage device stores a plurality of standard communication protocols; the storage device, the display device and the sensor are all in communication connection with the host; the embodiment comprises the following steps:
step S110: and generating a protocol corresponding file.
Specifically, the protocol correspondence file is a text file, which records a correspondence between the sensor address of each sensor and a standard communication protocol, and each sensor sends a message with the sensor address of the sensor sending the message, and the sensor address is unique (i.e., different sensor addresses of different sensors).
Step S120: acquiring a first message sent by the sensor, wherein the first message is a message sent by the sensor to the host for the first time, and the first message includes a sensor address of the sensor sending the first message.
Specifically, the sensor sends a first message to the host, and the host receives the first message, where the first message is a message sent by the sensor to the host for the first time, and the host does not know what communication protocol is used to parse the first message.
Step S130: all of the standard communication protocols are acquired.
Specifically, the host retrieves all standard communication protocols, such as Modbus-RUT, modbus-ASCII, etc., from the storage device.
Step S140: and analyzing the first message according to each standard communication protocol, judging whether the first message can be successfully analyzed, and obtaining first analysis data.
Specifically, since the sensor sends a message to the host for the first time, the sensor address in the first message does not have a corresponding standard communication protocol, and at this time, the first message is sequentially analyzed according to all the standard communication protocols until the first message is successfully analyzed and the first analysis data is obtained.
If yes, go to step S150: and displaying the first analysis data, establishing a first corresponding relation between the standard communication protocol for successfully analyzing the first message and the sensor address, and storing the first corresponding relation into the protocol corresponding file.
Specifically, if the first message is successfully analyzed, it is proved that a protocol capable of analyzing the first message exists in a preset standard communication protocol in the storage device, a first corresponding relationship is established between the protocol and a sensor address in the first message, where the first corresponding relationship actually corresponds a sensor and the standard communication protocol capable of analyzing the sensor message, so as to analyze a message sent by the sensor in the subsequent process, that is, when the sensor sends a message again, the standard communication protocol corresponding to the sensor is directly called to analyze the message.
And analyzing the first message into first analysis data, and displaying the first analysis data on a display.
Step S160: and acquiring a second message sent by the sensor, wherein the second message comprises the sensor address of the sensor sending the second message.
Specifically, the second message is different from the first message, that is, the second message is no longer the first message sent to the host.
Step S170: and judging whether the sensor address included in the second message has the corresponding standard communication protocol according to the protocol corresponding file.
Specifically, since the second message is actually a message sent to the host again after the first message (i.e., a message not sent to the host for the first time), if the first message sent by the sensor is analyzed normally, a standard communication protocol corresponding to the sensor address of the sensor exists (i.e., the first correspondence relationship between the sensor address of the sensor and the standard communication protocol is recorded in the protocol correspondence file).
Step S180: and if the second message exists, analyzing the second message according to the corresponding standard communication protocol to obtain second analysis data, and displaying the second analysis data.
Specifically, according to the first corresponding relationship, the host may directly analyze the second message by using the corresponding standard communication protocol to obtain second analysis data, where the second analysis data is a data value (e.g., a voltage value) detected by the sensor, and the second analysis data is displayed on the display.
For example, the sensor address of the first message corresponds to a standard Modbus-RUT communication protocol, the first message is 0203003425FA, and according to the standard Modbus-RUT communication protocol, 02 is an address code, i.e., a sensor address; 03 is a function code, which represents read data; 0034 represents the detection data of the sensor (the sensor takes a voltage sensor as an example, namely the detection data is three-phase voltage data), and since the data transmission in the industrial internet of things is 16-system, the three-phase voltage data obtained after the conversion of 0034 is 52KV; the 25FA is a check code for checking whether the first message is in error.
According to the general analysis method for the sensor data, a plurality of standard communication protocols are preset in storage equipment, wherein the standard communication protocols include but are not limited to common industrial internet of things common protocols, such as Modbus-RUT, modbus-ASCII and the like, when a host receives a first message sent by a sensor (namely, a message sent to the host by each sensor for the first time), the host can sequentially analyze the first message according to all the standard communication protocols until the first message is successfully analyzed and first analysis data are obtained, then establish a first corresponding relation between the standard communication protocol successfully analyzing the first message and the sensor address (namely, the sensor is corresponding to the standard communication protocol capable of analyzing the sensor message), and store the first corresponding relation in a protocol corresponding file; therefore, when the host equipment receives the message of the sensor again, the standard communication protocol corresponding to the sensor address of the sensor can be directly found through the protocol corresponding file, and the standard communication protocol is called to directly analyze the message received again subsequently.
By the technical scheme, different analysis programs do not need to be developed for the sensors adopting different communication protocols, and all common industrial Internet of things communication protocols on the market only need to be stored in the storage equipment, so that the universal analysis of the sent messages of different sensors can be completed; namely, the analysis program does not need to be changed, and the communication protocol adopted by the analysis program is changed, so that the method is very convenient and fast.
In a second embodiment of the method for universally parsing sensor data according to the present invention, based on the first embodiment, step S140 further includes the following steps:
if not, go to step S210: and acquiring a custom communication protocol.
Specifically, in practical applications, besides the regular communication protocol, some sensor manufacturers may also use their own defined communication protocol, and in this case, the messages sent by the sensors cannot be analyzed using the conventional standard communication protocol. A custom communication protocol defined by the sensor vendor itself is required. The customized communication protocol is manually input and stored in the storage device, and please refer to the third embodiment.
The number of custom communication protocols is 1 or more.
Step S220: and analyzing the first message according to each user-defined communication protocol, judging whether the first message can be successfully analyzed, and obtaining third analysis data.
Specifically, since the sensor address in the first message does not have a corresponding standard communication protocol, at this time, an attempt to perform resolution by using a custom communication protocol is required; the first message is sequentially analyzed according to all standard communication protocols until the first message is successfully analyzed and third analysis data is obtained.
If yes, go to step S230: and displaying the third analysis data, establishing a second corresponding relation between the user-defined communication protocol for successfully analyzing the first message and the sensor address, and storing the second corresponding relation into the protocol corresponding file.
Specifically, if the first message is successfully analyzed, it is proved that a custom communication protocol capable of analyzing the first message is stored in the storage device, a second corresponding relationship is established between the protocol and the sensor address in the first message, where the second corresponding relationship actually corresponds to the sensor and the custom communication protocol capable of analyzing the sensor message, so as to analyze the message sent by the sensor later, that is, when the sensor sends the message again later, the custom communication protocol corresponding to the sensor is directly called to analyze the message.
And analyzing the first message into third analysis data, and displaying the third analysis data on a display so as to be convenient for operators to use.
In a third embodiment of the method for universally analyzing sensor data according to the present invention, based on the second embodiment, step S160 further includes the following steps:
step S310: and judging whether the sensor address included in the second message has the corresponding user-defined communication protocol according to the protocol corresponding file.
Specifically, since the second message is actually a message sent to the host again after the first message (i.e., a message not sent to the host for the first time), if the first message sent by the sensor is analyzed normally, a standard communication protocol or a custom communication protocol corresponding to the sensor address of the sensor may exist (i.e., the first corresponding relationship between the sensor address of the sensor and the standard communication protocol or the second corresponding relationship between the sensor address of the sensor and the custom communication address may be recorded in the protocol corresponding file), which is the method that should be adopted when the sensor address included in the second message corresponds to the custom communication protocol.
If yes, go to step S320: and analyzing the second message according to the corresponding custom communication protocol to obtain fourth analysis data, and displaying the fourth analysis data.
Specifically, according to the second correspondence, the host may directly analyze the second message by using the corresponding custom communication protocol to obtain fourth analysis data, where the fourth analysis data is a data value (e.g., a voltage value) detected by the sensor, and the fourth analysis data is displayed on the display.
In a fourth embodiment of the method for universally analyzing sensor data according to the present invention, based on the second embodiment, step S320 further includes the following steps:
if not, execute step S410: generating first error information and displaying the first error information, wherein the first error information comprises the sensor address in the first message.
Specifically, if the first message is not analyzed through the stored standard communication protocol or the stored user-defined communication protocol, the first message indicates that the communication protocol adopted by the sensor is temporarily unknown or is not recorded in the storage device, and the first error information needs to be displayed on the display to remind an operator of timely processing.
In a fifth embodiment of the method for universal parsing of sensor data according to the present invention, based on the second embodiment, the system for universal parsing of sensor data further includes an information input device, where the information input device is in communication connection with the host; the embodiment further comprises the following steps:
step S510: the user-defined communication protocol input through the information input device is stored in the storage device, wherein the user-defined communication protocol includes a frame header value, a sensor address location value, a sensor address word length value, a function code location value, a function code word length value, a data type unit value, a data address location value, a data address word length value, a data block location value, a data block word length value, a check code location value, a check code word length value, and a frame tail value.
Specifically, the user-defined communication protocol is a text file, the number of the user-defined communication protocols is multiple, the communication protocols are respectively defined to correspond to the sensors which adopt the user-defined communication protocols for communication, relevant information of the user-defined communication protocols used by the sensors can be obtained from the use specifications of the sensors which adopt the user-defined communication protocols, and the user-defined communication protocols can be manually input according to the relevant information.
In this embodiment, the custom communication protocol includes: frame header, address, data type, data address, data block, check code, and frame trailer. A message can be correctly analyzed only by including all the contents; this custom format information can be obtained from the sensor's specifications.
For purposes of explanation, an embodiment of a custom communication protocol is illustrated herein in which the frame header value is FFFF, occupying 2 bytes; the position value of the sensor address is 3, which indicates that the sensor address begins to take a value from the 3 rd byte of the message, the word length value of the sensor address is 2, which indicates that the sensor address occupies 2 bytes; the position value of the function code is 5, which indicates that the function code begins to take value from the 5 th byte of the message, and the length value of the function code is 3, which indicates that the function code occupies 3 bytes; the data type value is a voltage value, and the data type unit value is KV; the data address position value is 8, which indicates that the data address begins to take values from the 8 th byte of the message, the data address word length value is 3, which indicates that the data address occupies 3 bytes; the data block position value is 11, which indicates that the data block begins to take value from the 11 th byte of the message, and the data block word length value is 4, which indicates that the data block occupies 4 bytes; the position value of the check code is 15, the check code starts to take values from the 15 th byte of the message, the check code word length value is 4, and the check code word length is 4 bytes; the end of frame value is DD.
For example, the host receives the following messages: FFFF030020050025SD05DD, the address of the message sensor is 03, the message corresponds to one embodiment of the self-defined communication protocol, and then the message can be analyzed according to the self-defined communication protocol to obtain analysis data, wherein the analysis process is that the frame head is FFFF and the frame tail is DD; the check code is checked to be correct, which shows that the message has no error; the function code is 002, which represents reading data, that is, the host reads the data in the storage space with the storage address of 005 from the sensor with the address of 03, the data is 0025, decimal conversion is performed to 37KV, the data is voltage data, which represents that the voltage value detected by the sensor is 37KV, and display is performed after conversion, so that the voltage value data can be read and understood.
Specifically, the data type values in the customized communication protocol include, but are not limited to, a voltage value, a current value, a temperature value, a humidity value, a speed value, and an illumination intensity value; in practice, the data types are in one-to-one correspondence with the types of sensors that are used to measure what data, and the data types here are what data are expressed.
In a sixth embodiment of the method for universal parsing of sensor data according to the present invention, based on the fifth embodiment, the step S220 includes the following steps:
step S610: generating a parsing list, wherein the parsing list is used for storing the custom communication protocol that has been adopted to parse the first message.
Specifically, sequential analysis of the custom communication protocols is managed by generating an analysis list so as to conveniently know which custom communication protocol has been adopted to analyze the first message, and the analysis list is stored in the storage device.
Step S620: and acquiring any one of the custom communication protocols, and judging whether the acquired custom communication protocol exists in the analysis list.
If yes, go to step S630: returning to step S620.
Specifically, the meaning here is to find a custom communication protocol that has not been used to parse the first message yet, because if the obtained custom communication protocol already exists in the parsing list, it is proved that the custom communication protocol has been adopted to parse the first message.
If not, go to step S640: and marking the acquired custom communication protocol as a current protocol, and judging whether the frame head value and the frame tail value in the current protocol simultaneously exist in the first message.
Specifically, when the current protocol is used for analyzing the first message, the frame head value and the frame tail value are found first, and then subsequent judgment is performed, and if the frame head value and the frame tail value are not matched, it is proved that the current protocol can certainly not analyze the first message, and subsequent analysis is not necessary.
Step S650: if the data address position value, the data address word length value, the data block position value and the data block word length value of the current protocol exist at the same time, data in a first message are read according to the data address position value, the data address word length value, the data block position value and the data block word length value of the current protocol, and first preliminary data are generated.
Specifically, for example, the word length of the data address is 3, which means that the data address occupies 3 bytes; the data block position value is 11, which indicates that the data block begins to take value from the 11 th byte of the message, and the data block word length value is 4, which indicates that the data block occupies 4 bytes; this way the first preliminary data in the first message can be read.
For example, if the first message is: FFFF030020050025SD05DD, and the first preliminary data of the packet is 0025.
Step S660: and converting the first preliminary data into second preliminary data through system conversion according to the system type of the first message.
Specifically, in this embodiment, the first message is hexadecimal, so that the decimal conversion result is 37.
Step S670: converting the second preliminary data into the third parsed data according to the data type value and the data type unit value of the current protocol.
Specifically, if the data type value is voltage data and the data type unit value is KV, the third analysis data is 37KV.
Step S680: if the protocol does not exist simultaneously, the current protocol is stored in the protocol list, and then whether all the self-defined communication protocols are included in the protocol list is judged.
Specifically, if the messages do not exist at the same time, the current protocol is proved to be incapable of analyzing the first message, and the subsequent analysis step is not performed; then storing the current protocol into the protocol list; and then judging the contents of the protocol list so as to judge whether all the self-defined protocols are analyzed.
Step S690: if yes, go to step S410.
Specifically, if included, it is verified that all the custom communication protocols are adopted, and the third analysis data may not be generated, so step S410 is directly performed.
Step S6110: if not, return to step S620.
Specifically, if not, it is verified that a custom communication protocol is not adopted, and the process directly returns to step S620 to perform the determination again.
In a seventh embodiment of the method for generic parsing of sensor data according to the present invention, based on the first embodiment, the method further comprises the following steps:
step S710: and acquiring data request information input through the information input equipment, wherein the data request information comprises a sensor address.
Specifically, the data request information includes the sensor address of the sensor requesting to be read, and after all the sensors send messages to the host, the sensor addresses of all the sensors are known.
Step S720: and judging whether a standard communication protocol corresponding to the sensor address exists or not according to the protocol corresponding file.
If yes, go to step S730: and compiling the data request information into a third message according to the corresponding standard communication protocol.
Step S740: and sending the third message to the sensor corresponding to the sensor address in the data request information.
Specifically, the technical solution of this embodiment actually converts the request sent to the sensor into a message recognizable by the sensor through a communication protocol, so as to implement bidirectional communication, i.e. compiling the data request information into a third message recognizable by the sensor, where the compiling process is completed according to a standard communication protocol corresponding to the sensor address of the target sensor to be sent.
In an eighth embodiment of the method for analyzing sensor data in general according to the present invention, based on the seventh embodiment, step S720 further includes the following steps:
if not, go to step S810: and judging whether a user-defined communication protocol corresponding to the sensor address exists or not according to the protocol corresponding file.
If yes, go to step S820: compiling the data request information into a fourth message according to the corresponding custom communication protocol.
Step S830: and sending the third message to the sensor corresponding to the sensor address in the data request information.
Specifically, the technical solution of this embodiment actually converts the request sent to the sensor into a message recognizable by the sensor through a communication protocol, so as to implement bidirectional communication, i.e., compiling the data request information into a third message recognizable by the sensor, where the compiling process is completed according to a custom communication protocol corresponding to the sensor address of the target sensor to be sent.
In a ninth embodiment of the method for analyzing sensor data in general according to the present invention, based on the eighth embodiment, step S810 further includes the following steps:
if not, go to step 910: and generating second error information and displaying the second error information, wherein the second error information comprises the sensor address in the data request information.
Specifically, if not, it is proved that the sensor address of the sensor to be sent of the data request information does not correspond to the standard communication protocol or the custom communication protocol, the host and the sensor to be sent cannot communicate with each other, and second error information needs to be generated, where the second error information includes the sensor address in the data request information, so as to facilitate the checking by an operator.
