Embodiment
Adopt the structure of vehicular-mounted transceiver and ground control centre transceiver, adopt the two-way simulation and verification platform of design of facing assembly.By vehicular-mounted transceiver by the order after group bag, data and information are sent to ground control centre by wire/radio network, the order of vehicular-mounted transceiver can process by ground control centre, call in scheduler handler, enter wait sequence, after order reaches beginning constraints, be sent to hardware emulator immediately, and start emulation, at regular intervals simultaneously, hardware emulator sends it back simulation status information, Straight simulation terminates, ground control centre or vehicular-mounted transceiver receive simulation result, and by process, send to ground control centre or vehicular-mounted transceiver, display simulation result.
As shown in Figure 1, be vehicle-mounted end transceiver architecture.On transmission data direction, in vehicle-mounted control sending and receiving end part, information type is divided into three types, command configuration file, data configuration file and source data.The effect of command configuration file is that the overall situation controls whole simulation process, and the effect of data configuration file is how configuration data processes, and source data is exactly data to be processed.Meanwhile, some train essential informations, and task indicates, and will be added in transport stream equally.These information spinners will be divided into allocating task number, and client-side information.The effect of allocating task number is, to the independently identification of each task matching, to be conducive to the tracking of data, and analysis.Client-side information is for indicating train information.Both combine and just can distinguish Data Source and with source place different task situation.
On reception data direction, data are received, and are reduced into client-side information and data and order three major types data.One by one after client-side information processing module processes, compare with source data, final formation comparison report.
When data configuration file carries out data processing and data packing, for reducing the demand to vehicle key message memory requirement and real-time, have employed the minimum of correction and carry out data compression with iterative algorithm, then this algorithm and scheduling strategy are combined, to reduce memory space and implementation complexity.First this algorithm only stores two values in the renewal of each check-node: the absolute value of minimum value, sub-minimum and minimum value position; And then store each sign bit (size equals the sum of " 1 " in check matrix).
As shown in Figure 2, be ground control centre framework.Data are received, and unpack, and are reduced into client-side information and data and order three major types data.Customer information is kept in client queue, when all data simulated good after, be that simulation result is packed together.Load in scheduler handler by data and order, wait task distributes.When task be assigned to corresponding hardware emulates time, data can be repeatedly mutual between queue and emulator, constantly to collect emulated data, final emulation is complete, result is put into end queue, wait pending data, order and client-side information packing send it back vehicle-mounted end transceiver.
As shown in Figure 3, multi-clock, multi code Rate of Chinese character, many compile modes changing method schematic diagram, for the exchange of mass data between vehicular-mounted transceiver and ground control centre, for ensureing the effective, quick of exchange, adopt multi-clock herein, multi code Rate of Chinese character, many compile modes changing method.Before coded data enters coding/decoding module, be introduced into a barrel-shaped buffer module, this module effectively can solve multi-clock, multi code Rate of Chinese character, when many compile modes switch, and the confusion of coding and decoding result.
The height of this barrel-shaped buffer module can be decided by code check and compile mode, because different code checks is not identical with the block size of compile mode.The spilling frequency of bucket is by clock, and code check and coding and decoding mode determine jointly, and data rate is determined by clock frequency.When bucket is full, data is packed together and be sent to encoder, effectively can solve the situation becoming clock, the dynamic change that bucket is high simultaneously, is solving multi code Rate of Chinese character, while the difficulty that many compile modes switch, does not lower efficiency.
