Embodiment Construction
[0038] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings. Apparently, the described embodiments are some, not all, embodiments of the present invention. Here, the exemplary embodiments of the present invention and their descriptions are mainly used to explain the present invention, but not to limit the present invention.
[0039] At present, a complete set of train overspeed protection equipment is relatively complicated, and generally consists of multiple boards, such as a main board, a communication board, an output board, an input board, etc.; each board has at least one processor ( Also referred to as CPU in the present invention). Form a hierarchical relationship between a plurality of boards, wherein, define "first-level board" as an external device tha...

The invention discloses an automated multiprocessor program update system comprising a primary board card and at least one secondary board card connected to primary board card; each of the board cardscomprises at least one processor; when a primary processor detects that there is any peripheral at ports of connecting lines with peripherals, the primary processor enters a wait state and commands secondary processors in a wait state, and identifies whether a target file name stored in the external is the same as a program name in each processor and the processor to which the program of the samename belongs; the target file with the same name is obtained from the peripheral to update and replace the program with the same name in the processor; after programs with the same name have been replaced and replaced, the processors at all levels resume a working state, and the primary board card will send out prompt signals to the outside. The invention also discloses an automated multiprocessor program update method. The technical scheme of the invention can avoid the problems of tedious work, low efficiency, easy error and the like in the process of manually updating different programs toa multi-processor.
Description
technical field [0001] The invention relates to a multiprocessor program update system and a program update method in a train overspeed protection system in a railway and urban rail transit operation control system, in particular to an automatic multiprocessor program update system and a program update method. Background technique [0002] Train overspeed protection system ATP (Automatic Train Protection) is one of the components of high-speed railway, subway and urban rail transit operation control system. operating under the standard. The on-board equipment for train overspeed protection is an important part of the train overspeed protection system. It is a safety guarantee equipment for real-time speed supervision of trains based on the train operation control commands received from the train overspeed protection ground equipment. [0003] At present, a complete set of train overspeed protection equipment is relatively complicated, and generally consists of multiple boar...
