For ease of understanding, each of the modules in the above-described apparatus will be described in detail below.
Firstly, a vehicle-mounted device communication module.
The maintenance service unit interfaces of different vehicle-mounted devices are not uniform, and comprise two communication modes of serial port communication and network TCP connection. In the embodiment of the invention, the communication module of the vehicle-mounted equipment is connected with the maintenance service unit of the vehicle-mounted equipment through the serial port interface or the network port interface, and establishes communication connection, namely two different communication modes (a serial port communication mode and a network TCP communication mode) are simultaneously supported, and switching is carried out according to different interfaces of the vehicle-mounted equipment.
When a serial port communication mode is used, data information in a computer serial port cache region in the vehicle-mounted equipment maintenance server unit is read continuously in a polling mode; when a network TCP communication mode is used, the data information is read by communicating with the vehicle-mounted equipment maintenance server unit through a TCP protocol.
And the vehicle-mounted equipment communication module stores the read data information into a vehicle-mounted binary data queue for the vehicle-mounted data analysis module to call. When the data of the vehicle-mounted equipment does not need to be read, a corresponding command can be sent through the communication module of the vehicle-mounted equipment to inform the maintenance service unit to stop sending the data.
And secondly, a vehicle-mounted data analysis module.
In the embodiment of the invention, the vehicle-mounted data analysis module analyzes the data information received by the vehicle-mounted equipment communication module and extracts effective information in the data information. Specifically, the method comprises the following steps: the vehicle-mounted data is usually coded in a binary format in the communication process, and the vehicle-mounted data analysis module is responsible for restoring the read data information in the binary format into basic information and recording the basic information.
The vehicle-mounted data analysis module reads corresponding binary data from the vehicle-mounted binary data queue through an open interface of the vehicle-mounted equipment communication module, decodes the binary data stream into corresponding information by adopting different protocols according to different types of vehicle-mounted equipment, selects the corresponding decoded and restored information according to different train operation grades, and stores the information into the train running information queue.
And thirdly, a vehicle-mounted data sending module.
In the embodiment of the invention, the vehicle-mounted data sending module extracts corresponding decoded and restored information from the train running information queue of the vehicle-mounted data analyzing module to recombine according to the information type requirement of the high-speed railway train control system simulation test platform, encodes the information into a binary data stream, and transmits the binary data stream to the high-speed railway train control system simulation test platform.
Preferably, in consideration of decoupling and speed, the vehicle-mounted device communication module, the vehicle-mounted data analysis module and the vehicle-mounted data transmission module are respectively allocated with an independent sub-thread, and the three threads do not interfere with each other and communicate by means of interfaces between the threads.
The scheme of the embodiment of the invention mainly has the following beneficial effects:
1) the vehicle-mounted data analysis device is separated from the vehicle-mounted equipment, and universality is high.
The invention can adopt different communication modes (serial communication/network TCP communication) to connect different types of vehicle-mounted equipment and adopts different protocols to analyze. One set of equipment is compatible with multiple vehicle-mounted equipment, and the universality is strong. Besides, the system does not need additional hardware equipment except the computer, and is convenient to deploy.
2) The train control system simulation test platform is directly connected with a vehicle-mounted maintenance unit, has strong flexibility and is more suitable for a train control system simulation test platform of a high-speed railway.
The train operation data acquisition device is directly connected with the vehicle-mounted maintenance unit to acquire all train operation data including train running data and driver operation information, can freely define information sent to the high-speed railway train control system simulation test platform according to different requirements, is high in flexibility, and meets the requirements of the high-speed railway train control system simulation test platform.
3) The vehicle-mounted equipment communication module, the vehicle-mounted data analysis module and the vehicle-mounted data sending module are mutually independent, so that the maintenance is easy, and the expansion is convenient.
The invention distributes three independent sub threads to a vehicle-mounted equipment communication module, a vehicle-mounted data analysis module and a vehicle-mounted data sending module respectively. The three modules are independent from each other, the operation of other modules is not influenced by modifying the internal logic of any one module, and the three modules are easy to maintain and convenient to expand.
It will be clear to those skilled in the art that, for convenience and simplicity of description, the foregoing division of the functional modules is merely used as an example, and in practical applications, the above function distribution may be performed by different functional modules according to needs, that is, the internal structure of the system is divided into different functional modules to perform all or part of the above described functions.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
