Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The Tbox is a key component for communication of the automobile terminal Internet of vehicles, and after the CAN bus in the vehicle collects the message signal to the Tbox, the Tbox sends the message signal to the cloud. When the Tbox collects the message signal, if the Tbox does not receive the required signal in the message signal transmission period, it will generally fill a reserved value (without practical meaning) to express, but as the magnitude of the signal increases continuously, for controlling the bus load, part of the signal will not be reserved value, and when the signal is not received, it will select the valid value as default filling. When the analysis is applied, the effective value and the default filling value may not be clearly distinguished, so that data is abnormal, and the analysis result is influenced.
In view of the problems in the prior art, the inventors of the present application have conducted creative research to provide a Tbox invalid signal value determination method for improving the above problems.
Referring to fig. 1, an embodiment of the present application provides a Tbox invalid signal value determining method, which may include the following steps.
Step S110: and acquiring a record value corresponding to the signal value to be identified.
In this embodiment, a register may be disposed in the Tbox.
The register CAN be used for recording the receiving condition of the Tbox to the message signal transmitted by the CAN bus in each message signal transmission period and generating a recorded value. The recorded value is used to characterize whether the signal was received by the Tbox.
In an embodiment, in each message signal transmission cycle, if the Tbox receives a message signal transmitted through the CAN bus, the recorded value may be a first preset value; if the Tbox does not receive the message signal transmitted through the CAN bus, the recorded value may be the second preset value. Illustratively, the first preset value may be 0, and the second preset value may be 1.
Illustratively, the register may be a register having a multi-bit. Each bit records the receiving condition of a message signal.
Step S120: and when the recorded value is determined to be the first preset value, determining that the signal to be identified is an invalid signal.
In this embodiment, the first preset value is used to represent that the signal is not received by the Tbox, so that when it is determined that the recorded value of the signal corresponding to the value of the signal to be identified is the first preset value, it may be determined that the Tbox does not receive the signal, and accordingly, the value of the signal to be identified corresponding to the signal is an invalid signal value.
It can be understood that, for the case that the Tbox does not receive the required signal in the message signal transmission period and fills the Tbox with the reserved value, when the recorded value of the signal corresponding to the signal value to be identified is determined to be the second preset value (the second preset value represents that the signal is received by the Tbox), it may be determined that the Tbox receives the signal, and accordingly, the signal value to be identified corresponding to the signal is the valid signal value.
For the case that the default padding is performed by using the valid value on the basis of the padding by using the reserved value, it is necessary to further determine whether the signal value to be identified is an invalid signal value. Therefore, in this embodiment, the method may further include the following steps.
Step S130: and when the signal value to be identified is determined to be out of the preset range, determining the signal value to be identified as an invalid signal value.
In this embodiment, the valid signal value is obtained as follows: a plurality of message signals are contained in the same message, and the signal value of the message signal required by the Tbox is set as an effective signal value; when the message signal value is not the value required by Tbox, the message signal value is an invalid signal value.
In this embodiment, the preset range is a discrete value set or a continuous value interval. The preset range is set according to the effective signal value, so that the preset range can comprise all the effective signal values. Specifically, because the message signal values of different messages are different, it is difficult to set the message signal values uniformly, so that when the valid signal value is a discrete value, the preset range is set as a discrete value set, and when the valid signal value is a continuous value, the preset range is set as a continuous value interval.
In this embodiment, through will treat the identification signal value and predetermine the scope contrast, when confirming that treat the identification signal value and be located outside predetermineeing the scope, confirm that treat the identification signal value as invalid signal value, can do further screening to the signal of output to cloud ware, distinguish out invalid signal value not within predetermineeing the scope fast, to a certain extent, improve the efficiency of judging the signal, when improving Tbox and cloud ware data interaction's instantaneity, further make the data that the high in the clouds was used for carrying out the analysis more accurate, and then further make the analysis result that obtains more reliable.
Step S140: when the signal value to be identified is determined to be within the preset range, determining whether the associated information of the signal value to be identified meets a preset judgment condition; and if so, determining the signal value to be identified as an invalid signal value.
In one embodiment, a method for determining whether a signal value to be recognized is an invalid signal value according to whether associated information of the signal value to be recognized satisfies a predetermined condition is provided.
In this embodiment, when the associated information of the signal value to be identified is a message signal in the same message from which the signal value to be identified is located, and the preset determination condition is that an invalid signal exists in the message signal in the same message from which the signal value to be identified is located, the signal to be identified is determined as the invalid signal. Specifically, a plurality of message signals are in the same message, generally, the message signal values in the same message are the same, and when the signal value to be identified is in the same message and contains an effective signal value, the rest of the message signal values are also the effective signal values; correspondingly, when the same message does not contain the valid signal value, the signal values in the message are all invalid signal values, and the signal value to be identified is determined to be an invalid signal.
In this embodiment, when the correlation information of the signal value to be recognized is the correlation data of the signal to be recognized, the preset determination condition is that the correlation data of the signal value to be recognized is an invalid signal value, and the signal value to be recognized is determined as an invalid signal value. Specifically, the associated data may be data having an inverse relationship and the same value, such as a requested value and a feedback value, an actual value and a meter display value, or other data pair having the same function. When one of the values of the associated data is determined to be an invalid signal value, the other value of the associated data may also be determined to be an invalid signal value. Therefore, when the associated data of the signal to be recognized is an invalid signal value, the signal to be recognized is also determined as an invalid signal value.
In this embodiment, when the correlation information of the signal value to be recognized is the actual meaning value represented by the signal value to be recognized, the preset determination condition is that the signal to be recognized is determined as an invalid signal when it is determined that the actual meaning value represented by the signal value to be recognized is abnormal. Illustratively, the actual meaning value of the signal representation is mileage, and the mileage is generally increased but not decreased or changed to 0, and when the signal value representing mileage indicates that the mileage is decreased or changed to 0, the signal is considered to be an invalid signal.
In the present embodiment, different determination conditions are provided, and the invalid signal may be determined in different manners, and those skilled in the art will understand that the use of the invalid determination condition may be one of the conditions or any combination of the conditions. The output signal value is judged for the second time through the preset judgment condition, the invalid signal and the valid signal are distinguished for the second time, and the inaccuracy of data analyzed and output by the cloud server caused by the fact that the invalid signal is sent to the cloud server to be analyzed or the valid signal is judged to be the invalid signal is reduced, so that the accuracy of the data is improved.
In this embodiment, by further determining the value of the signal to be recognized within the preset range, the accuracy of the determination result can be improved on the premise that the efficiency of the Tbox outputting the message signal is maintained at a high level, so that the data accuracy of the analysis result of the cloud server is improved on the premise that the instantaneity and the efficiency of the cloud server analysis are not affected.
