Description

Technical Field

[0001] The present invention relates to the field of automotive electronics manufacturing technology, and in particular to a multi-electronic control flash writing device based on a vehicle off-line. Background Art

[0002] With the development trend of vehicle intelligence, more and more controllers are integrated into the whole vehicle, which puts forward more complex requirements for the flashing of the whole vehicle controller. Compared with the mode of flashing the electronic control in sequence one by one at the previous generation of flashing stations, the Chinese patent document with publication number CN216411899U proposes an online flashing device for engine control unit, which connects the industrial computer with multiple controllers through a connector, and can flash the engine control units of multiple vehicles at the same time.

[0003] However, when the above solution is running, the computing power of an industrial computer must support the flashing process of multiple controllers at the same time, which makes the industrial computer burdened. In addition, when a single controller flashes abnormally, it may affect other controllers, which does not conform to the low coupling and modularization concept of program design. In addition, a flashing station in this solution can only be used for a single type (engine) controller of a single model, and cannot meet the diverse needs of flashing the entire vehicle controller.

[0004] The existing multi-controller flashing test bench is only developed for a single type of controller. This patent supports flashing of multiple types of controllers at the same time through configurable flashing process files.

[0005] The existing solution concentrates the control and execution process of flashing multiple controllers in the same industrial computer. This has two disadvantages: first, the flashing processes of multiple controllers may affect each other, and an abnormality in a single process will affect other processes; second, the control stage and the execution stage are highly coupled, which does not meet the software programming principles. Summary of the invention

[0007] Furthermore, the storage rack is specifically a four-layer stepped storage rack, the top layer is provided with a barcode scanner and a printer, and each of the remaining three layers is provided with two writing slots.

[0008] Furthermore, a lighting lamp group is also arranged on the top of the shelf, and the lighting lamp group is specifically a plurality of groups of LED lamp tubes.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0020] like Figure 1 , Figure 2 As shown, the present invention provides a multi-electric control flashing device based on the whole vehicle off-line, including a barcode scanner, a printer, a display, a stand, a cabinet, a flashing slot, and a relay group; the display is embedded in the upper part of the stand, and the cabinet is fixedly installed at the lower end of the stand, and a shelf is installed between the display and the cabinet; a barcode scanner and a printer are arranged on the top layer of the shelf, and a plurality of flashing slots are arranged under the shelf; the relay group is arranged and installed on the back of the cabinet.

[0021] The rack is a four-layer stepped rack, the top layer is equipped with a barcode scanner and a printer, and the remaining three layers are each equipped with two writing slots. A lighting group is also provided at the top of the rack, and the lighting group is specifically a plurality of LED light tubes.

[0022] The flash slot is a fixture type device that can hold the controller. One end of the device is connected to the interface of the controller, and the other end is connected to the programmable power supply and the lower computer. One flash slot corresponds to one lower computer. A cooling fan is installed on the device to keep the temperature of the controller normal.

[0023] The cabinet is equipped with an industrial computer, power supply components, refrigeration and air conditioning, and switches. There are multiple lower computers under the cabinet. The lower computers are connected to the flashing slots one by one. The industrial computer is used to send flashing tasks and parameter information, process files, and production files related to the tasks to the lower computers. The switch is connected to the lower computer and the industrial computer through a network cable. The relay group is connected to the switch power supply, the lower computer, and the industrial computer respectively. The industrial computer is equivalent to the upper computer and is responsible for sending flashing tasks and parameter information, process files, production files, etc. related to the tasks to the lower computers. One industrial computer can control six lower computers at the same time and is connected to the display. The industrial computer synchronously displays the flashing status information sent by the lower computer on the display.

[0024] The relay group connects the lower computer and the three-color indicator light; the industrial computer controls the relay group through the IO card, thereby controlling the power on and off of the lower computer and the flashing indicator light of the flash slot; the industrial computer controls the power on and off of the ECU controller through the programmable power supply.

[0025] The power supply components specifically include: UPS power supply, programmable power supply, and switching power supply; the UPS power supply is used to provide uninterrupted power supply to the test stand; the programmable power supply is used to power the flash writing slot and is connected to the industrial computer through a USB interface; the switching power supply is used to power the lower computer.

[0026] The lower computer is a communication VCI device that supports CAN, CANFD, DOIP-TX, and DOIP-T1 communications. A cooling fan is provided on the flashing slot to control the temperature change in the flashing slot during flashing. The external power supply voltage of the multi-electric flashing device is specifically 220V.

[0027] The lower computer is essentially a dual-core communication controller. The M core is a single-chip microcomputer that encapsulates the protocol layer program for communicating with the controller and exposes the communication interface to the A core. The A core is a Linux operating system. The flash program in it receives the task information sent by the upper computer and communicates with the vehicle controller through the communication interface. In this way, the flash task is executed while the flash status information is transmitted upward. The upper computer sends the process file of the flash task to the lower computer, and the process file can be configured separately for various flash processes of different controllers.

[0028] The working principle of the device provided by the present invention is specifically as follows: the operator needs to insert the controller into the slot fixture of the flashing station; the upper computer obtains the flashing task and verification task information from the flashing management platform according to the controller type supported by the fixture, and sends the flashing task to the lower computer to execute the flashing, and monitors the flashing progress of the lower computer in real time. After the flashing task is completed, the upper computer collects and organizes the flashing results, and sends the result data back to the upstream flashing management platform. When the flashing is abnormally interrupted, the upper computer supports the flashing task fallback mechanism to ensure that the task information is not lost and the production rhythm is not affected; when the flashing equipment is abnormal, the upper computer can generate early warning information and send it back to the upstream flashing management platform. In addition, the flashing stand supports the flashing of large-size domain controllers, supports docking with the cooling system during flashing, heat dissipation treatment of the controller, and so on.

[0029] The present invention separates the control phase and the execution phase of the flashing process, and places them in the upper computer and the lower computer respectively, so as to realize the modularization and low coupling of the program. At the same time, the present invention realizes that one lower computer corresponds to one controller, and realizes the separation of the execution process of flashing multiple controllers without affecting each other.

[0030] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
