Description
Technical field
The present invention relates to train supervision field.
Background technology
Along with CBTC (Communication Based Train Control, communication-based train control) development of technology, VOBC (Vehicle On-Board Control, vehicle control syetem) dynamic data also increasingly sophisticated property and integrality, an independently-powered LDC (Local Data Collector, datalogger) is used to become a kind of inevitable trend.For the transformation of data recording fashion, following several conditions must be met:
1) suitable installation site is designed.The method of existing collection dynamic data is the special notebook of use one, be unfavorable for that client secure is runed, therefore existing ATC (Auto Train Control is not being changed, driverless train controls) under subrack condition, need design one independently datalogger LDC and independently power and design an installation site, ensure that existing ATC equipment is not affected.
2) communication protocol reasonable in design.The dynamic data length of existing VOBC is fixed, and comprise several variablees, and variable not can customize.On the basis not affecting the existing communication protocol of VOBC, define a new agreement, user can the length of online modification dynamic data, and can custom variable.
3) suitable security.Mobile unit, vehicle control syetem concerns the safety of passenger, and therefore LDC needs to have high security.
4) suitable economy.Product development cost can not be too high, otherwise be unfavorable for promoting and producing.
Summary of the invention
The object of the present invention is to provide a kind of vehicle-mounted data recorder, to coordinate vehicle control syetem.
The present invention also aims to the container structure providing a kind of vehicle-mounted data recorder, specification structure, reduces volume and cost.
The technical scheme realizing above-mentioned purpose is:
A kind of vehicle-mounted data recorder, external VOBC, comprise central processing unit, and the ethernet module be connected with described central processing unit respectively, USB (USB (universal serial bus)) module, RS232 module, power module, RS422/485 module, external memory module, FLASH (flash memory) module and ID (identify label number) module, wherein:
Described ethernet module connects described VOBC, for transmission and mutual dynamic data;
