Embodiment 1
[0048] Embodiment 1 of the present invention proposes a remote calibration method for sensor production lines, which can be applied to the remote calibration system for sensor production lines described in Embodiment 1 to realize LDW (lane departure warning system), MRR (medium range radar monitoring system), Sensor calibration for automotive ADAS modules or systems such as BSD (Blind Spot Monitoring System).
[0049] figure 1 It is a flowchart of a remote calibration method for a sensor production line in Embodiment 1, see figure 1, the method includes the following steps S101 to S106:
[0050] Step S101 , when the vehicle needs to be calibrated, the device server obtains the calibration parameters according to the model number of the vehicle, and controls the calibration device to run to a designated location.
[0051] For example, during the final assembly of the car in the step, the vehicle enters the calibration station, that is, the testing station, and the device serv...
Embodiment 2
[0095] Such as Figure 4 As shown, Embodiment 2 of the present invention proposes a sensor production line remote calibration system, which is used to implement the sensor production line remote calibration method described in Embodiment 1. The system includes a device server 1, a calibration device 2, and a TBOX server 3 and vehicle TBOX4.
[0096] In a preferred embodiment, as Figure 5 As shown, the system further includes: RFID device 5 and RFID server 6 .
[0097] The RFID device 5 is used to identify the RFID beacon on the vehicle to obtain the vehicle VIN code when the vehicle enters the calibration station, and judge whether the vehicle is a legal vehicle according to the vehicle VIN code, and if it is legal, then the vehicle VIN code Send to RFID server 6.
[0098] The RFID server 6 is used to judge whether the vehicle is a legal vehicle according to the VIN code of the vehicle, and if it is a legal vehicle, then send a vehicle arrival signal to the device server 1...

Abstract
The invention relates to a sensor production line remote calibration method and system, and the method comprises the steps that when a vehicle needs to be calibrated, an equipment server obtains calibration parameters, controls calibration equipment to run to a designated position, and transmits an equipment in-place signal and the calibration parameters to a TBOX server; the TBOX server generates a calibration diagnosis instruction according to the equipment in-place signal and the calibration parameter and sends the calibration diagnosis instruction to the vehicle TBOX; the vehicle TBOX forwards the calibration diagnosis instruction to the ECU; the target ECU calibrates the sensor according to the calibration diagnosis instruction to obtain a calibration result, generates a calibration result instruction according to the calibration result and returns the calibration result instruction to the vehicle TBOX; and the calibration result instruction TBOX server analyzes the calibration result instruction and sends an analysis result to the equipment server for display. According to the invention, the problem of mistake proofing of the remote calibration station of the sensor production line and the limitation problem of burning the calibration instruction to the TBOX for remote calibration in advance can be solved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a remote calibration method and system for a sensor production line. Background technique [0002] With the development of the intelligent connection function of the vehicle, more and more sensors are equipped in the vehicle, and these sensors need to be calibrated before leaving the factory. Whether the vehicle needs to be calibrated is determined by the employees themselves through the information such as the instrument, which increases the risk of missing the standard. For vehicles that need to be calibrated, employees first scan the barcode of the vehicle, and the equipment recognizes the barcode to judge the model and start the calibration. This manual operation method prolongs the calibration time of the station, and at present, employees directly scan the barcode in the vehicle before performing calibration. There is no verification mechanism on the equipment side, an...
