Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
A data transmission control method according to some embodiments of the present invention is described below with reference to fig. 1 to 3. The data transmission control method is executed by the data transmission initiating terminal, and the data transmission initiating terminal can be a data processing system in the working machine or a data acquisition system in the working machine. It can be understood that the data transmission control method is suitable for working machines, such as heading machines, coal mining machines and the like, which have overlarge bus resource occupation caused by more communication data. As shown in fig. 1, a data transmission control method according to an embodiment of the present invention at least includes the following steps:
S101, determining a data transmission cycle of source data based on parameter information of the source data and preset grouping information when the data transmission requirement is determined; the data transmission cycle is used for representing the transmission times and the data quantity of each transmission;
s102, based on the data transmission cycle, controlling the source data to carry out grouping and time-sharing transmission until the source data transmission is completed or the source data transmission fails.
In this embodiment, the data transmission requirement may be a data reading requirement or a data writing requirement; the data reading requirement is that the data transmission initiating terminal needs to read the source data from the data transmission receiving terminal; the data writing requirement, that is, the data transmission initiator needs to send the source data to the data transmission receiver. The source data is data to be transmitted, for example, may be process data in a working process of the working machine. If the data transmission initiating terminal is a data processing system, when the data reading requirement is determined to exist, the source data can be controlled to be grouped and transmitted in a time-sharing mode so as to read the source data from the data transmission receiving terminal; if the data transmission initiating terminal is a data acquisition system, when the data writing requirement is determined to exist, the source data can be controlled to be grouped and transmitted in a time-sharing mode so as to write the source data from the data transmission initiating terminal to the data transmission receiving terminal. That is, when the data transmission initiator is a data processing system, the data transmission receiver may be a data acquisition system, and when the data transmission initiator is a data acquisition system, the data transmission receiver may be a data processing system.
The determination mode of whether the data transmission requirement exists may be set according to the actual requirement, for example, the data transmission requirement may be determined when a data transmission instruction is received, or the data transmission requirement may be determined when the data processing requirement exists based on the operation state of the working machine.
The parameter information of the source data can be working condition parameters corresponding to the source data, taking fully mechanized mining face automatic cutting working conditions as an example, the parameter information of the source data can comprise the number W of process segments, and can also comprise sampling point numbers, sampling positions, mining heights, speeds, dip angles and the like. The parameter information of the source data can be set through the data transmission initiating terminal or through the data transmission receiving terminal.
The preset grouping information may be a grouping mode when the source data is transmitted in a grouping mode. Taking the fully-mechanized mining face automatic cutting working condition as an example, the preset grouping information can be the grouping number of each process segment, for example, the sampling points of each process segment are divided into N groups.
The data transmission cycle of the source data is used to characterize the number of transmissions and the amount of data per transmission, for example, the total amount of data of the source data may be determined based on the parameter information of the source data, the number of data groups may be determined based on the preset grouping information, and as the number of transmissions, so that the amount of data per data group is determined based on the total amount of data of the source data, the number of data groups, and as the amount of data per transmission P, P may be less than or equal to 50. In addition, the source data may be further grouped based on a preset transmission sequence of each sub data in the source data, the number of data groups, and the data amount of each data group, so as to obtain a plurality of data groups, and the transmission sequence of each data group. The preset transfer order may be determined based on the job order corresponding to each sub data, for example, the order of the job order from front to back and the data amount of each data group, the source data may be divided into a plurality of data groups, and may be determined based on the data transfer priority of each sub data, for example, the order of the data transfer priority from high to low and the data amount of each data group, the source data may be divided into a plurality of data groups. Taking the fully-mechanized mining face automatic cutting working condition as an example, a W-N double-layer cycle can be constructed, namely, the numbers of the process sections are cycled from 1 to W, and meanwhile, for any process section, the group numbers of the data groups are cycled from 1 to N.
The specific mode of controlling the source data to carry out grouping and time-sharing transmission based on the data transmission cycle can be that based on the data transmission cycle, one data group is controlled to carry out transmission in each cycle, and the grouping and time-sharing transmission of the source data is realized, so that the occupation amount of bus resources can be effectively reduced, and the influence on other data communication is avoided. Meanwhile, the data transmission initiating terminal and the data transmission receiving terminal only need to process the data group required to be transmitted in the current cycle in each cycle, so that the requirement on the data processing capacity of the data transmission initiating terminal and the data transmission receiving terminal is effectively reduced, and the risk of system blocking or delay is reduced.
In the process of controlling source data to carry out grouping and time-sharing transmission based on the data transmission cycle, if all data sets corresponding to the source data are transmitted, or when the data sets in the previous cycle are failed to be transmitted, the data transmission cycle can be exited to ensure effective transmission of the data.
In this embodiment, when the data transmission initiator determines that there is a data transmission requirement, based on the parameter information of the source data and preset packet information, a data transmission cycle for characterizing the transmission times of the source data and the data amount transmitted each time is determined, and based on the data transmission cycle, the source data is controlled to perform packet and time-sharing transmission until the transmission of the source data is completed or the transmission of the source data fails, so that the occupation amount of bus resources can be effectively reduced, and the influence on other data communications is avoided. Meanwhile, the requirement on the data processing capacity of the data transmission initiating end and the data transmission receiving end is effectively reduced, and the risk of system blocking or delay is reduced.
In an exemplary embodiment, the controlling the source data to perform packet and time-sharing transmission based on the data transmission cycle includes:
determining data information of data to be transmitted of the source data in the current cycle based on the data transmission cycle;
controlling the data to be transmitted based on the first transmission control data, the second transmission control data and the data information of the data to be transmitted; the data transmission initiating terminal sends the first transmission control data to the data transmission receiving terminal based on a preset frequency, and receives the second transmission control data sent by the data transmission receiving terminal.
In this embodiment, in the process of controlling the source data to be grouped and time-division transmitted based on the data transmission cycle, for any cycle of the data transmission cycles, the data information of the data to be transmitted in the current cycle of the source data may be determined based on the data transmission cycle, for example, the data information of the data to be transmitted in the current cycle may be determined based on the data transmission cycle and the transmission sequence of each data group. The data to be transmitted in the current cycle is the data group to be transmitted in the current cycle, and the data information of the data to be transmitted is the grouping parameter of the data group. Taking the fully-mechanized mining face automatic cutting working condition as an example, the data information of the data to be transmitted in the current cycle can comprise the serial numbers of the process sections and the group numbers of the data groups.
After the working machine is started, the data transmission initiating terminal can send first transmission control data to the data transmission receiving terminal based on a preset frequency, and meanwhile, the data transmission receiving terminal can send second transmission control data to the data transmission initiating terminal based on the preset frequency, namely, the data transmission initiating terminal and the data transmission receiving terminal can communicate in real time through the first transmission control data and the second transmission control data.
When there is a data transmission demand, the data transmission initiating terminal can send a data transmission request and a data transmission stopping request through the first transmission control data, and the data transmission receiving terminal can send response information of data transmission through the second transmission control data so as to control the data to be transmitted in the current cycle to be transmitted, namely, source data only needs to be transmitted when there is a data transmission demand, the transmission of the source data is not needed in real time, and the occupied bytes of the first transmission control data and the second transmission control data which are transmitted in real time are fewer, so that the occupation amount of bus resources is further reduced.
When the data transmission requirement does not exist, the parameter information of the source data can be sent based on the first transmission control data or the second transmission control data, real-time interaction of working condition parameters can be achieved, and when the data transmission requirement exists, the data transmission cycle can be timely determined based on the parameter information of the source data.
In an exemplary embodiment, the controlling the data to be transmitted based on the first transmission control data, the second transmission control data, and the data information of the data to be transmitted includes:
if the data transmission requirement is a data reading requirement, setting a communication identifier in the first transmission control data as a first identifier, and configuring data information of the data to be transmitted in the first transmission control data;
based on the communication identification in the second transmission control data, when the response of the data transmission receiving end is successful, acquiring first transmission data sent by the data transmission receiving end; when the data transmission receiving end recognizes that the communication identifier in the first transmission control data is the first identifier, the data transmission receiving end obtains the data to be transmitted from the source data based on the data information of the data to be transmitted, sends the data to be transmitted to the data transmission initiating end as the first transmission data, and when the first transmission data is obtained and sent successfully, sets the communication identifier in the second transmission control data as a second identifier.
In this embodiment, the first transmission control data and the second transmission control data may each include a communication identifier field and a transfer parameter field, where the communication identifier field is used to write a communication identifier, the communication identifier may be used to characterize data transmission request information or response information at the current time, and the transfer parameter field may be used to write data information of the data to be transmitted. It will be appreciated that when there is no data transmission requirement, the communication identifier may be set to a preset identifier, e.g. "regular", and the transfer parameter may be set to null. The data transmission receiving end may modify the content of the transfer parameter field in the second transmission control data based on the content of the transfer parameter field in the first transmission control data sent by the data transmission initiating end.
When the data transmission initiating terminal determines that the data reading requirement exists, the data transmission initiating terminal indicates that the data transmission initiating terminal needs to read source data from the data transmission receiving terminal, at this time, a communication identifier in the first transmission control data can be set as a first identifier, and data information of data to be transmitted in the current cycle is configured in a transfer parameter field in the first transmission control data. Wherein the first identification may be used to characterize the data read request, e.g. may be a "data read request".
The data transmission receiving end identifies a communication identifier in the first transmission control data after receiving the first transmission control data, if the communication identifier in the first transmission control data is the first identifier, further obtains the data to be transmitted in the current cycle from the source data stored by the data transmission receiving end based on the data information of the data to be transmitted configured by the transfer parameter field in the first transmission control data, and sends the data to be transmitted as the first transmission data to the data transmission initiating end, and meanwhile, when the first transmission data is obtained and sent successfully, the communication identifier in the second transmission control data is set as the second identifier. Wherein the second identification may be used to characterize the success of the response, e.g., may be "response success".
After receiving the second transmission control data, the data transmission initiating terminal identifies the communication identifier in the second transmission control data, if the communication identifier in the second transmission control data is the second identifier, the data transmission receiving terminal is determined to respond successfully, and the first transmission data sent by the data transmission receiving terminal is acquired, so that closed loop transmission control of the data to be transmitted is realized through the communication identifier in the first transmission control data and the communication identifier in the second transmission control data, and the reliability of data transmission is effectively ensured.
The data transmission initiating terminal can read the first transmission data in the process of acquiring the first transmission data sent by the data transmission receiving terminal, and update the data according to the read data.
In addition, when the data transmission initiating terminal recognizes that the communication identifier in the second transmission control data is the second identifier, the data transmission initiating terminal can further acquire the content of the transmission parameter field in the second transmission control data, compare the content of the transmission parameter field in the first transmission control data with the content of the transmission parameter field in the first transmission control data, and acquire the first transmission data sent by the data transmission receiving terminal if the content of the transmission parameter field and the content of the transmission parameter field are consistent, so that the reliability of data transmission is further improved.
In an exemplary embodiment, further comprising:
when the first transmission data acquisition is determined to be completed, setting a communication identifier in the first transmission control data as a third identifier; when the data transmission receiving end recognizes that the communication identifier in the first transmission control data is the third identifier, the data transmission receiving end sets the communication identifier in the second transmission control data as the third identifier and stops sending the first transmission data.
In this embodiment, when determining that the first transmission data acquisition is completed, the data transmission initiator may set the communication identifier in the first transmission control data to be a third identifier, so as to complete the data transmission in the current cycle. The third identification is used to characterize that there is no data transfer requirement, e.g., may be "regular".
In the process of sending the first transmission data, if the communication identifier in the first transmission control data is identified as the third identifier, the data transmission receiving end stops sending the first transmission data, sets the communication identifier in the second transmission control data as the third identifier, finishes the current cycle execution, waits for the data reading request of the next cycle, and further avoids the influence of real-time transmission of the source data on the occupation amount of bus resources.
And when the last cycle execution of the data transmission cycle is finished, the transmission of the source data is completed.
In an exemplary embodiment, further comprising:
based on the communication identifier in the second transmission control data, determining that the response of the data transmission receiving end fails or fails, setting the communication identifier in the first transmission control data as a third identifier, and exiting the data transmission cycle; and when the first transmission data acquisition fails or the transmission fails, the data transmission receiving end sets the communication identifier in the second transmission control data as a fourth identifier.
In this embodiment, in the process of acquiring the data to be transmitted in the current cycle from the source data stored in the data transmission receiving end, if the data to be transmitted fails to acquire or fails to transmit in the process of transmitting the data to be transmitted to the data transmission initiating end, the data transmission receiving end sets the communication identifier in the second transmission control data as the fourth identifier. Wherein the fourth identification may be used to characterize a response failure, e.g., may be "response failure".
In addition, if the data transmission receiving end does not receive the first transmission control data with the communication identifier being the first identifier, or if the data transmission receiving end fails to identify or identifies errors in the process of identifying the communication identifier in the first transmission control data, the communication identifier in the second transmission control data still keeps the third identifier unchanged.
In the process of identifying the communication identifier in the second transmission control data, the data transmission initiating terminal determines that the response of the data transmission receiving terminal fails if the communication identifier in the second transmission control data is the fourth identifier, and determines that the data transmission receiving terminal does not respond if the communication identifier in the second transmission control data is the third identifier. It can be appreciated that the duration of the data transmission initiator for acquiring the first transmission data may be less than the time interval corresponding to the preset frequency.
When the data transmission initiating terminal identifies that the data transmission receiving terminal fails or fails in response, the data transmission initiating terminal determines that the data transmission to be transmitted fails in the current cycle, and can set the communication identifier in the first transmission control data as a third identifier and exit the data transmission cycle, so that the reliability of the data transmission is effectively ensured. Meanwhile, by the method of the embodiment, when the data transmission receiving end sends the first transmission data by mistake due to logic errors and the like, the data transmission initiating end cannot receive the first transmission data because the communication identifier in the second transmission control data is the third identifier, so that the reliability of data transmission is further improved.
In addition, when the data transmission initiating terminal identifies that the data transmission receiving terminal fails to respond or does not respond, the data transmission initiating terminal can also generate error reporting information and send the error reporting information to a preset terminal, and the preset terminal can be a vehicle-mounted display device or a remote monitoring terminal so as to facilitate timely troubleshooting.
In an exemplary embodiment, the controlling the data to be transmitted based on the first control data, the second control data, and the data information of the data to be transmitted includes:
if the data transmission requirement is a data writing requirement, setting a communication identifier in the first transmission control data as a fifth identifier, configuring data information of the data to be transmitted in the first transmission control data, acquiring the data to be transmitted from the source data based on the data information of the data to be transmitted, and sending the data to be transmitted to the data transmission receiving end as second transmission data;
based on the communication identification in the second transmission control data, stopping sending the second transmission data when the data transmission receiving end is determined to respond successfully, and setting the communication identification in the first transmission control data as a third identification; the data transmission receiving end acquires the second transmission data when recognizing that the communication identifier in the first transmission control data is the fifth identifier, and sets the communication identifier in the second transmission control data as a second identifier when the second transmission data acquisition is completed.
In this embodiment, when the data transmission initiator determines that there is a data writing requirement, it indicates that the data transmission initiator needs to write the source data stored in itself into the data transmission receiver, at this time, the communication identifier in the first transmission control data may be set to a fifth identifier, and the data information of the data to be transmitted in the current cycle may be configured in the transfer parameter field in the first transmission control data. Wherein the fifth identification may be used to characterize the data write request, for example, may be "data write request". Meanwhile, the data transmission initiating terminal also acquires the data to be transmitted in the current cycle from the source data stored by the data transmission initiating terminal based on the data information of the data to be transmitted, and sends the data to be transmitted to the data transmission receiving terminal as second transmission data.
The data transmission receiving end identifies the communication identifier in the first transmission control data after receiving the first transmission control data, acquires the second transmission data if the communication identifier in the first transmission control data is the fifth identifier, and sets the communication identifier in the second transmission control data as the second identifier when the acquisition of the second transmission data is completed. Wherein the second identification may be used to characterize the success of the response, e.g., may be "response success".
After receiving the second transmission control data, the data transmission initiating terminal identifies the communication identifier in the second transmission control data, if the communication identifier in the second transmission control data is the second identifier, the data transmission initiating terminal determines that the data transmission receiving terminal responds successfully, stops sending the second transmission data, and sets the communication identifier in the first transmission control data as a third identifier so as to complete the data transmission of the current cycle. The third identification is used to characterize that there is no data transfer requirement, e.g., may be "regular".
When the data transmission receiving end recognizes that the communication identifier in the first transmission control data is a third identifier, the data transmission receiving end can also set the communication identifier in the second transmission control data as the third identifier, and the current cycle execution is finished and waits for the data writing request of the next cycle, so that the influence of real-time transmission of the source data on the occupation amount of bus resources is further avoided. Meanwhile, closed-loop transmission control of data to be transmitted is realized through the communication identifier in the first transmission control data and the communication identifier in the second transmission control data, and the reliability of data transmission is effectively ensured.
The data transmission receiving end can read the second transmission data in the process of acquiring the second transmission data sent by the data transmission initiating end, and update the read data to the data according to the data information of the data to be transmitted configured by the transfer parameter field in the first transmission control data.
In addition, at the end of the last cycle execution of the data transmission cycle, the transmission of the source data is completed.
In an exemplary embodiment, further comprising:
based on the communication identifier in the second transmission control data, determining that the response of the data transmission receiving end fails or fails, stopping sending the second transmission control data, setting the communication identifier in the first transmission control data as the third identifier, and exiting the data transmission cycle; and when the second transmission data acquisition fails, the data transmission receiving end sets the communication identifier in the second transmission control data as a fourth identifier.
In this embodiment, in the process of identifying that the communication identifier in the first transmission control data is the fifth identifier and obtaining the second transmission data, if the second transmission data is not received, or if the second transmission data is received but the second transmission data cannot be effectively read or written, the data transmission receiving end sets the communication identifier in the second transmission control data to the fourth identifier. Wherein the fourth identification may be used to characterize a response failure, e.g., may be "response failure".
In addition, if the data transmission receiving end does not receive the first transmission control data with the communication identifier being the fifth identifier, or if the data transmission receiving end fails to identify or identifies errors in the process of identifying the communication identifier in the first transmission control data, the communication identifier in the second transmission control data still keeps the third identifier unchanged.
In the process of identifying the communication identifier in the second transmission control data, the data transmission initiating terminal determines that the response of the data transmission receiving terminal fails if the communication identifier in the second transmission control data is the fourth identifier, and determines that the data transmission receiving terminal does not respond if the communication identifier in the second transmission control data is the third identifier. It can be understood that the duration of the data transmission receiving end for acquiring the second transmission data may be less than the time interval corresponding to the preset frequency.
When the data transmission initiating terminal identifies that the data transmission receiving terminal fails or fails in response, the data transmission initiating terminal determines that the data to be transmitted in the current cycle fails in transmission, stops sending the second transmission data, sets the communication identifier in the first transmission control data as a third identifier, and exits the data transmission cycle, so that the reliability of data transmission is effectively ensured. Meanwhile, by the method of the embodiment, when the data transmission initiating terminal sends the second transmission data by mistake due to logic errors and the like, the data transmission receiving terminal cannot receive the second transmission data because the communication identifier in the first transmission control data is the third identifier, so that the reliability of data transmission is further improved.
In addition, when the data transmission initiating terminal identifies that the data transmission receiving terminal fails to respond or does not respond, the data transmission initiating terminal can also generate error reporting information and send the error reporting information to a preset terminal, and the preset terminal can be a vehicle-mounted display device or a remote monitoring terminal so as to facilitate timely troubleshooting.
In an exemplary embodiment, the first transmission control data and the second transmission control data each include a source data parameter field; the source data parameter field is used for configuring parameter information of the source data.
In this embodiment, the first transmission control data and the second transmission control data may further include a source data parameter field, where the source data parameter field is used to configure parameter information of the source data. It may be appreciated that the parameter information of the source data may be set by the data transmission initiator, or may be set by the data transmission receiver, for example, before the working of the working machine or when the working condition parameters of the working machine change.
In practical application, if the data transmission requirement is a data reading requirement, the data transmission receiving end can set the parameter information of the source data, and when the data transmission initiating end determines that the data transmission requirement exists, the data transmission initiating end can obtain the parameter information of the source data based on the content of the source data parameter field in the second transmission control data sent by the data transmission receiving end, and meanwhile, the data transmission initiating end can modify the content of the transmission parameter field in the first transmission control data based on the content of the source data parameter field in the second transmission control data.
If the data transmission requirement is a data writing requirement, the data transmission initiating terminal can set the parameter information of the source data, when the data transmission initiating terminal determines that the data transmission requirement exists, the data transmission initiating terminal can obtain the parameter information of the source data based on the content of the source data parameter field in the first transmission control data, and meanwhile, the data transmission receiving terminal can modify the content of the transmission parameter field in the second transmission control data based on the content of the source data parameter field in the first transmission control data sent by the data transmission initiating terminal.
