Description
Technical Field
The invention relates to an offline detection mode of a vehicle networking terminal (T-BOX).
Background
The vehicle network becomes the normal state of the automobile industry, and the intellectualization and networking become the trend of automobile development. There is an increasing demand for a terminal for a vehicle networking (TBOX) that can be networked through a network and various terminals to control electronic devices inside a vehicle. The TBOX system can assist in achieving functions of audio-video entertainment, vehicle diagnosis, vehicle information display, mobile phone APP networking display and the like, when a user binds a vehicle-mounted TBOX through a mobile phone, the user can send a control command through the APP, a background can transmit a request command to the vehicle-mounted T-BOX, then the control over the vehicle can be directly achieved, an operation result is synchronously fed back to the APP, and typically, the vehicle is remotely started, a skylight is opened, an air conditioner is opened and the like. The cloud, the pipe and the end are three indispensable conditions of a vehicle network, so the requirements on a production line are very strict. Some unbound vehicles can cause that the vehicles cannot be used for branding (vehicles in Beijing six), and the requirements of landmark regulations cannot be met, and certainly, a series of functions cannot be used, the complaint rate of users is high, and the requirements for offline detection are higher.
The current offline detection protocol is shown in the following table:
| scheme(s) | Key binding | Write configuration | T-service detection | Reading factory value |
| Scheme 1 (domestic TBOX) | Y | Y | Y | TBD |
| Scheme 2 (foreign TBOX) | Y | Y | N | Y |
| Of significance | Information tracking, TSP platform and PDCS platform need to acquire | Configuring VIN and function items | Detecting connection state values of TBOX and TSP | Detecting connection state values of TBOX and TSP |
Since foreign sim cards cannot connect our platforms, it is not possible to implement domestic methods for foreign applications from a tabular perspective. The following problems are currently encountered with export projects: vehicles can only go to foreign ports TBOX for background connection, and the current export to brazil has the problem, and the reason has not been found out so far.
Therefore, there is a need for a new tbox offline detection scheme for the batch of export project vehicles. But this is only the original purpose, and it is also necessary to realize that the on-board T-BOX does not see the compatibility check for your product.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a novel T-BOX offline detection scheme so as to better realize the vehicle-mounted T-BOX offline detection.
The technical scheme adopted by the invention is as follows:
a T-BOX offline detection method adopts a Ford global standardized detection scheme, utilizes WIFI communication in a factory to realize connection check of a TBOX and a background, and monitors the state of the TBOX in the factory, and comprises the following steps:
s1, TBOX connecting to WiFi and using WiFi for configuration and data transmission;
s2, TBOX offline configuration write flow:
when the T-BOX is on the offline detection station, the VIN code and the configuration code of the vehicle need to be written, then the T-BOX conducts self-diagnosis, reads the fault DTC and judges whether the T-BOX is normal in function or not;
s3, importing basic data of the MES system into a TSP database:
after the VIN code of the vehicle and the T-Box are in a binding relationship and enter the MES system, synchronizing data from the MES system to a service flow of the TSP platform;
and S4, reading the state value of the vehicle diagnosis DID through VACATS to judge whether the offline process is missed.
In the method for detecting the offline of the T-BOX, in step S2, the offline configuration of the TBOX is written into the process, and the specific logic is as follows:
1) when the whole vehicle reaches an off-line detection station, the T-BOX is automatically started after the whole vehicle is powered on;
2) opening VCATS and scanning VIN;
3) scanning the SAP;
4) performing an operation, waiting for a result
5) The result is normal and passes the detection; and if the result is abnormal, filling off-line configuration failure information in the car-following order, wherein the information comprises the steps of writing VIN, writing TBOX configuration files, reading fault information and clearing fault information.
In the T-BOX offline detection method, in step S3, the business process of importing basic data of an MES system into a TSP database has two parts of automatic synchronization and manual synchronization; under normal conditions, data are automatically synchronized in a scheduled time interval, and when synchronization is wrong or the data synchronization requirement is met in an interval time period, manual synchronization is carried out in an operation management system.
The invention has the beneficial effects that:
according to the T-BOX offline detection method, the VACATS is used for reading and comparing the state value of the vehicle diagnosis DID to judge whether the offline flow of the vehicle/vehicle networking module is omitted or not, and the new offline mode can forbid the step of the T service, so that the beat of a project is accelerated, and the production efficiency is improved.

Detailed Description
The technical solution of the present invention is further described in detail below by means of specific embodiments and with reference to the accompanying drawings.
Example 1
Referring to fig. 1, 2 and 3, the offline detection method of the T-BOX of the present invention adopts ford global standardized detection scheme, and utilizes WIFI communication in a factory to realize connection check of the T-BOX and a background, and realize real-time monitoring of the state of the T-BOX in the factory, which comprises the following steps:
s1, connecting the T-BOX to the WiFi and using the WiFi for configuration and data transmission;
s2, writing process of T-BOX offline configuration:
when the T-BOX is on the offline detection station, the VIN code and the configuration code of the vehicle need to be written, then the T-BOX conducts self-diagnosis, reads the fault DTC and judges whether the T-BOX is normal in function or not;
s3, importing basic data of the MES system into a TSP database:
after the VIN code of the vehicle and the T-Box are in a binding relationship and enter the MES system, synchronizing data from the MES system to a service flow of the TSP platform;
and S4, reading the state value of the vehicle diagnosis DID through VACATS to judge whether the offline process is missed.
Example 2
Referring to fig. 1 to 3, the method for offline inspection of T-BOX of the present embodiment is different from embodiment 1 in that: further, in step S2, the specific logic of the write flow of TBOX offline configuration is as follows:
1) when the whole vehicle reaches an off-line detection station, the T-BOX is automatically started after the whole vehicle is powered on;
2) opening VCATS and scanning VIN;
3) scanning the SAP;
4) performing an operation, waiting for a result
5) The result is normal and passes the detection; and if the result is abnormal, filling off-line configuration failure information in the car-following order, wherein the information comprises the steps of writing VIN, writing TBOX configuration files, reading fault information and clearing fault information.
Example 3
The difference between the offline detection method of the T-BOX in the embodiment and the embodiments 1 and 2 is that: further, in step S3, the business process of importing the basic data of the MES system into the TSP database has two parts, namely, automatic synchronization and manual synchronization; under normal conditions, data are automatically synchronized in a scheduled time interval, and when synchronization is wrong or the data synchronization requirement is met in an interval time period, manual synchronization is carried out in an operation management system.
The automatic synchronization temporary synchronization time is 15 min/time. The manual synchronization is that when the MES passes the point, the MES system synchronizes the data to the TSP, which is a domestic method, because the SIM card is a domestic card, can be connected with a background and directly surf the internet, whether a link is normal can be judged through remote control vehicle condition query, and the result guidance can also prove that the TBOX configuration is normal and the binding of the TBOX and the vehicle is correct.
For foreign schemes (i.e., the new scheme herein) we make changes at this step. And (5) factory detection for determining whether the finished automobile can be taken out of a final assembly plant, wherein the detection station is temporarily set as offline detection.
In the off-line detection method of the T-BOX, in step S4, the value of D221 is read for JMC autonomous brands:
setting TBOX as Factory Mode when leaving Factory; d221 state value 00;
2. TBOX completes writing the configuration function D221 state value 01;
3. d221 state value 02 after TLS establishment of TBOX and TSP is successful;
4. TBOX and TSP 0/1 interact through, D221 state value 05;
5, TSP completes real-name authentication, D221 state value 06;
d221 > =5 indicates that JMC can be extracted.
D221 is a vehicle diagnostic DID (identifier) of our JMC autonomous brand, whose contents are definable, and this value is configurable, as the case may be, by each garage itself. The situation of our car factory is as follows:
therefore, whether the offline process is omitted or not can be judged through the value read by the VACATS, and the new offline mode can forbid the step of the T service, so that the beat of the project is accelerated, and the production efficiency is improved.
The invention discloses a T-BOX offline detection method, which has the following configuration requirements on T-BOX: TBOX has the function of connecting to and configuring with WiFi (check device channel), FD24 resource deployment Uniform Resource Locator (URL), FD25 wlan.ssid, FD26 wlan.psk, FD27 wlan.sw (ssid/password must not be read from DID perspective), FD08 setup method (cell/WiFi), FDXX WiFi client/server mode (configuration required to be WiFi client/server mode); the TBOX vendor EOL configures the FD08 setup method to cellular and the FDXX to WiFi server mode.
EOL of the car factory: WiFi infrastructure setup, frequency (2.5/5 GHZ), allowing TBOX to connect to TMC guidance service; garage EOL configuration FD08 (configuration method), FDXX (WiFi client/server); FD08 is configured as a cellular method before the truck plant EOL leaves the plant; d021 DID was checked before total assembly, D021 = 0x10, FD08 = cellular configuration method, FDXX = WiFi server mode. If the correct value cannot be read, the vehicle should be sent to a service area. And uploads the reads D021, FD08, FDXX DID read to the JMC PDCS Portal. The PDCS needs to receive the values of D021, FD08, FDXX.
