Problems solved by technology

However, the default filling value is an invalid signal value. During the application analysis, the cloud server will analyze both the valid signal value and the invalid signal value received from Tbox. Among them, the analysis of the invalid signal value will cause the cloud server data to be abnormal, thus affecting the analysis. result

Embodiment Construction

[0038] 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.

[0039] Tbox is a key component of the IoV communication of the car terminal. The CAN bus inside the vehicle collects the message signal to the Tbox, and then the Tbox sends it to the cloud. When Tbox collects the message signal, if it does not receive the required signal within the message signal transmission period, it will generally fill in a reserved value (with no practical meaning) to represent it, but as the signal level continues to increase, for To control the bus load, some signals will not be used as reserved values. When no signal is received, effective values ​​will be selected for default filling. When applying analysis, it may not be possible to distinguish valid values ​​from default fill values, resulting in data anomalies and affecting analysis results.

Abstract

The application provides a Tbox invalid signal value judging method, device, electronic equipment and computer-readable storage medium, which relate to the field of vehicle networking communication. The Tbox invalid signal value judging method includes: obtaining the record value of the signal to be identified, and the record value is used to indicate whether the signal is received by Tbox; when the record value is determined to be a first preset value, determining the signal to be identified is an invalid signal, wherein the first preset value indicates that the signal is not received by the Tbox. The invalid signal value output by Tbox to the cloud server is judged, so that the cloud server does not analyze the invalid signal, thereby improving the accuracy of data analysis.

Description

technical field [0001] The present application relates to the field of vehicle networking communication, in particular, to a method, device, electronic device and computer-readable storage medium for judging an invalid signal value of Tbox. Background technique [0002] Tbox (Telematics BOX) is a key component of the Internet of Vehicles communication of the car terminal. The car Tbox can deeply read the CAN bus data and private protocol of the car. The Tbox can position the vehicle through the GPS (Global Positioning System, Global Positioning System) The module outputs data to the cloud server through the network, and the car owner can obtain vehicle condition reports, driving reports, fuel consumption, faults and other vehicle information in the cloud server through the network. [0003] However, when Tbox collects message signals through the CAN bus, if it does not receive the required signal within this period, it will generally fill in a reserved value to indicate it. ...
