Problems solved by technology

[0005] When the key parameters of the existing LonWorks gateway device such as the configuration address of the LonWorks gateway device itself, the addressing address of the implicit destination device, and the size of the converted data change, it is necessary to use proprietary third-party software and hardware to communicate between the LonWorks communication unit and the CPU data processing unit. Burn the program separately for reconfiguration, the burning time is long, the operation is very inflexible, and cannot adapt to the current large number of trains and the frequent modification of configuration file parameters on the LON side due to scheduling
At the same time, due to the diversity of customer needs for train communication, different communication requirements protocols need to change key parameters such as the address of the LonWorks gateway device and the size of the converted data, and constantly change the key configuration parameters of the LonWorks gateway device for on-site applications according to the diverse project requirements Personnel maintenance update brings great inconvenience

Embodiment 1

[0022] The invention discloses a configuration method of a Lonworks gateway device, such as figure 1 shown, including:

[0023] Step S1, creating a configuration file on the CPU side for modifying parameters on the LON side.

[0024] In this step, the configuration file can be in XML format, and the key parameters that can be modified in the configuration file include but are not limited to any one or any combination.

[0025] Step S2, the CPU end initiates a negotiation to synchronize the configuration file to the LON end.

[0026] In this step, the specific negotiation can be divided into: the CPU side judges whether the LON side is online; then, after judging that the LON side is online, the CPU side transmits the configuration file to the LON side, and judges whether the LON side reads the configuration file successfully. After the reading is successful, after the CPU end assigns the corresponding configuration parameters in the configuration file to the corresponding a...

Embodiment 2

[0038] Corresponding to the foregoing method embodiments, this embodiment discloses a Lonworks gateway device that executes the foregoing methods.

[0039] The system of this embodiment includes: a CPU end, which is used to create a configuration file for modifying parameters on the LON end, and initiates a negotiation that the configuration file is synchronized to the LON end; The corresponding configuration parameters are assigned to the corresponding application interface functions. Optionally, the RS232 bus is used for data transmission between the FT-5000 protocol chip on the CPU side and the LON side. The specific configuration file can be in XML format. The key parameters that can be modified in the configuration file include but are not limited to the configuration address of the LonWorks gateway device itself, Any one or any combination of implicit destination device addressing address and converted data size.

[0040] Preferably, after the negotiation fails, each ap...

Abstract

The invention relates to the technical field of rail transit and discloses a Lonworks gateway device and a configuration method thereof so as to improve the flexibility and the convenience of configuration modification. The method of the invention comprises that a CPU end creates a configuration file for modifying the parameters of a LON end; the CPU end initiates the negotiation of synchronizingthe configuration file to the LON end; if the negotiation is successful, the LON end assigns the corresponding configuration parameters in the configuration file to a corresponding application interface function; and if the negotiation fails, the application interface functions of the LON end use the existing configuration.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a Lonworks gateway device and a configuration method thereof. Background technique [0002] A train usually includes a motor car / control car and a trailer, wherein the motor car / control car is a carriage with driving force, and the trailer is a carriage without traction. At present, the motor car / control car usually uses MVB (Multifunction Vehicle Bus, multifunctional vehicle bus) for interconnection of related devices, while the trailer usually uses LonWorks (a field bus) for interconnection of related devices. [0003] The LonWorks gateway device is based on the LonWorks bus. Its proprietary FT-5000 protocol chip converts other bus-type data and LonWorks data. For example, it converts the MVB data of the motor car / control car on the train and the LonWorks data of the trailer. [0004] For the existing LonWorks gateway equipment, refer to the patent No. 201620903543.9, whi...
