The on-board data collector is arranged on a subway train. The on-board data collector is connected with the controller. The displayer is connected with the controller. Compare with prior art, the subway train security data collecting and analyzing system has the advantages that real-time collection of on-board data, mass storage and graphical reflection of conditions of subway trains are achieved, maintenance efficiency is improved and the like.
Description
Technical field
The utility model relates to a kind of data processing system, especially relates to a kind of subway train secure data acquisition analysis system.
Background technology
The subway line has experienced " 4 turn 2 ", " 6 change 8 " and stages such as " new 8 cars " in succession since ATP/ATO (train automatic protection and automatic train operation) function comes into operation in succession, vehicle is many, the train that comes into operation is many, the operation interval is little.And ATC (Automatic Train Control, train is controlled automatically) system introduces from the U.S., because contract and technical know-how do not provide during introduction and the systems technology parameter of runing relevant key equipment, and operation maintenance has been caused certain difficulty.The relevant data of this ground wire cab signal system can only be recorded in the EEPROM of system CPU plate at present, because the finite capacity of EEPROM, system only provides the monitoring of simply preserving the function of some final event recorders reports in the short time and not having intermediate variable, thereby device fails particularly moment occur fault the time, so that service personnel can not find the foundation of dealing with problems, cause the failure analysis difficulty, fault handling time prolongs.Therefore be necessary On-board ATC relevant all key messages, particularly security information are carried out real-time dynamic data monitoring and record.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of realize vehicle-mounted data Real-time Collection and large capacity storage, graphically reflect train status, improve the subway train secure data acquisition analysis system of maintenance efficiency.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of subway train secure data acquisition analysis system, comprise Data Acquisition System for Vehicle, controller and telltale, described Data Acquisition System for Vehicle is arranged on the subway train, and described Data Acquisition System for Vehicle is connected with controller, and described telltale is connected with controller.
Described Data Acquisition System for Vehicle comprises On-board ATC interface, embedded scm, real time clock circuit, storage card, 232 interfaces and power module, described embedded scm connects respectively On-board ATC interface real time clock circuit and storage card, described 232 interfaces connect storage card, described power module connects respectively embedded scm and real time clock circuit, and described 232 Interface and Controler connect.
Described subway train is provided with train 110V power supply, and described power module is connected with train 110V power supply.
Described storage card is the SD card.
Comprise data reading circuit, data transfer and the distributor circuit and the data preservation module that connect successively in the described controller.
Compared with prior art, the utlity model has following advantage:
1) realize vehicle-mounted data Real-time Collection and large capacity storage: system adopts embedded technology, with crossing serial ports Real-time Collection On-board ATC data, and utilize SD card (2G) storage of collected TXT text data, and it is long to have a storage data time, and data format is unified characteristics simply;
2) the graphical playback of vehicle operating: the data after processing by controller can be in telltale graph-based out, can be by position and the status information of time at station field pattern reflection train, shortened the time of failure analysis and location, make failure analysis simple, vivid, improve maintenance efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic flow sheet of the utility model Data Acquisition System for Vehicle;
Fig. 3 is the schematic flow sheet of the utility model controller.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of subway train secure data acquisition analysis system, comprise Data Acquisition System for Vehicle 1, controller 2 and telltale 3, described Data Acquisition System for Vehicle 1 is arranged on the subway train, described Data Acquisition System for Vehicle 1 is connected with controller 2, and described telltale 3 is connected with controller 2.
In the present embodiment, Data Acquisition System for Vehicle 1 comprises On-board ATC interface 11, embedded scm 12, real time clock circuit 13, storage card 14,232 interfaces 15 and power module 16, described embedded scm 12 connects respectively On-board ATC interface 11, real time clock circuit 13 and storage card 14, described 232 interfaces 15 connect storage card 14, described power module 16 connects respectively embedded scm 12 and real time clock circuit 13, and described 232 interfaces 15 are connected with controller 2.Described subway train is provided with train 110V power supply, and described power module 16 is connected with train 110V power supply.Described storage card 14 is the SD card of 2G for capacity, and the data of storing in the card are the TXT text data of uniform layout.In the present embodiment, 232 interfaces 15 are provided with two.
As shown in Figure 2, the data acquisition of Data Acquisition System for Vehicle 1 may further comprise the steps:
1) carries out initialization;
2) whether cycle criterion SD card is plugged, if be plugged, then the SD card is carried out initialization;
3) real time clock circuit reads the current time, and embedded scm is set up catalogue on the same day, is saved to the SD card;
4) embedded scm sends to the On-board ATC interface and begins to take orders, and begins to gather current data, and data is preserved under the corresponding catalogue of SD card.
Comprise data reading circuit, data transfer and the distributor circuit and the data preservation module that connect successively in the described controller 2.Controller 2 can read the data that Data Acquisition System for Vehicle gathers by 232 interface real-time onlines, also can read by the storage card off-line in the Data Acquisition System for Vehicle data that Data Acquisition System for Vehicle gathers.
As shown in Figure 3, the principle of work of controller is: data reading circuit reads the TXT file data that Data Acquisition System for Vehicle gathers; The original data that reads is carried out the conversion of ACSII code 16 systems for data transfer and distributor circuit and data allocations is processed, and with EXCEL document form save data; Data are preserved module and are preserved through each TXT file of allocation process with and by the EXCEL file of after treatment TXT Generating Data File.
Because it is hexadecimal format that Data Acquisition System for Vehicle collects data, we are difficult to the Direct Analysis processing under windows.So the hexadecimal system TXT file conversion that need will gather and produce first becomes the hexadecimal system TXT file of ASCII character, so that whether analyze the data that collect correct; In order to generate the EXCEL document of being convenient to Direct Analysis, the hexadecimal system TXT file that needs to convert ASCII character to distributes combined treatment.
The information that shows in the telltale 3 comprises ATS information, vehicle self information, vehicle interface I/O information, trackside information interface, a control interface and station full figure interface, also can in telltale, carry out the graphical playback of running state of the vehicle, in time fault is analyzed and located, make failure analysis simple, vivid, improved maintenance efficiency.
