In the drawings:

[0011] Figure 1 is a whole view of a vehicle lamp batch flashing or diagnosis system based on a Mesh network. DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0013] Unless otherwise defined, all the technical and scientific terms used in the present application have the same meanings as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The term "and / or" used in the present application includes any and all combinations of one or more related listed items.

[0014] The present application provides a vehicle lamp batch flashing or diagnosis system based on a Mesh network, as shown in Figure 1 The PC end and the vehicle lamp unit with Bluetooth Mesh technology are wirelessly connected, the connected vehicle lamp units form a Bluetooth mesh network, the PC end synchronously transmits the flashing / diagnosis information to each vehicle lamp unit in a broadcast form, and batch flashing / diagnosis of the vehicle lamp units is realized.

[0015] When matching, the vehicle lamp units that need to be matched can be manually selected through the PC end, the connected vehicle lamp units form a Bluetooth mesh network, each vehicle lamp unit is an internal node of the Bluetooth mesh network module, the PC end sends the flashing / diagnosis information to all nodes in a broadcast form, so as to uniformly send the flashing / diagnosis information and realize targeted batch processing.

[0016] The vehicle lamp unit includes a vehicle lamp module and a Bluetooth device, the vehicle lamp module is wirelessly connected with the PC end through the Bluetooth device, and data intercommunication between the PC end and the vehicle lamp module is realized. The vehicle lamp module includes a plurality of vehicle lamp groups and a vehicle lamp control module, the vehicle lamp control module stores a vehicle lamp program, when the vehicle lamp program has a problem, the vehicle lamp groups cannot normally operate, and need to be diagnosed or flashed to ensure normal operation of the vehicle lamp groups.

[0017] The car light control module is in data intercommunication with the car light group and the Bluetooth device through the CAN bus, and the car light control module can control different car light groups to act respectively, and can also be in data intercommunication with the Bluetooth device.

[0018] The Bluetooth device comprises a CAN-to-Bluetooth module, a Bluetooth-to-CAN module, a power module and a Bluetooth mesh network module. The Bluetooth mesh network module is used to match with the PC end, receive or send wireless signals using the Bluetooth Mesh protocol, and realize data intercommunication with the PC end; the Bluetooth-to-CAN module is used to convert the Bluetooth signals received by the Bluetooth mesh network module into CAN signals and transmit the CAN signals to the car light control module; the CAN-to-Bluetooth module is used to convert the CAN signals output by the car light control module into Bluetooth signals and send the Bluetooth signals through the Bluetooth mesh network module; and the power module is used to power the Bluetooth device.

[0019] The working principle and working process of the utility model are as follows:

[0020] Matching: the PC end is matched to the to-be-flashed / diagnosed car light module in the Bluetooth mesh networking through the Bluetooth device, and each to-be-flashed / diagnosed car light module is a car light node;

[0021] Broadcasting: the PC end sends flashing / diagnosing broadcast information to all the matched car light nodes in the Bluetooth Mesh network, so as to inform the car light nodes to act and make them send available flashing / diagnosing data;

[0022] Reply: when the to-be-flashed / diagnosed car light node receives the flashing / diagnosing broadcast information, the car light node determines whether it needs to receive the flashing / diagnosing operation; if yes, the to-be-flashed / diagnosed car light node is determined, and the to-be-flashed / diagnosed car light node sends the information needing to accept the flashing / diagnosing to the PC end based on the Bluetooth Mesh protocol; if no, the flashing / diagnosing broadcast information is ignored;

[0023] Flashing / diagnosing: when the nodes in the to-be-flashed / diagnosed car light node group under the Bluetooth mesh network receive the broadcast information needing to accept the flashing / diagnosing, the nodes perform flashing / diagnosing on the to-be-flashed / diagnosed car light node, and in the flashing / diagnosing process, the to-be-flashed / diagnosed car light node performs transmission of the flashing / diagnosing data through the CAN protocol.

[0024] Feedback: after all the to-be-flashed / diagnosed car light nodes complete the flashing / diagnosing, the node flashing / diagnosing feedback information is fed back to the PC end again through the Bluetooth Mesh protocol of the Bluetooth device, and the PC end collects the flashing / diagnosing feedback information of all the nodes.

[0025] The embodiments of the present application are described in detail above, but the content is only the preferred embodiments of the present application, and cannot be considered to limit the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the scope of the present patent.
