On the one hand the train running information can be obtained from serial communication bus between the monitoring device main machine and display, at the same time the the information can be transferred into all the module units, on the another hand the informations fed back from all the module units can be real-time recorded.
Description
Train operation monitoring and recording device (hereinafter to be referred as control monitor unit) is is generally installed and used in the electric locomotive of railway as the safety protection equipment of train operation, no matter be locomotive check implement or information transmission equipment, all wish to obtain the relevant essential information of train operation by control monitor unit, as time, kilometer post, speed, train number etc., and carry out various detection recording of informations as reference coordinate with these information.In recent years, some auxiliary security information relevant with locomotive operation detect and information transmission equipment is come out one after another, and begin test or local utilization, as track dynamic check implement, bow net check implement, train dispatching radiophone locomotive station voice recording equipment, TMIS and DMIS train running information transmission equipment etc.But these equipment are produced or trial-production by different research institutes respectively, have a style of one's own, and disperse to install on locomotive, and systematicness is not strong, and the wasting of resources is big; Moreover owing to do not combine, do not have to overlap floor control system support preferably again, cause the information availability of record poor, be not easy to analyze and unified management with the information such as time, kilometer post, speed and train number of train operation.For this reason, necessary with these equipment centralization, systematization, and set up unified workplatform, various check implements and information transmission equipment are placed workplatform with the standard feature modular unit.And control monitor unit is a key equipment of guaranteeing train operating safety, and its performance mainly is to prevent that train from advancing rashly and exceed the speed limit, and the security information of real time recording train operation is so that analyze.If achieve the above object by the hardware and software of transforming control monitor unit, certainly will the control monitor unit system be soft, the complexity of hardware with increasing, reduce the system reliability index, finally cause influencing original monitoring of control monitor unit and writing function, jeopardize train operating safety, this is never desirable! Moreover the software and hardware resources of control monitor unit is restricted to a great extent, transform on this basis, the expansion capacity, to increase function impossible substantially.
The objective of the invention is to propose a kind of common platform that has at the deficiency of existing engine monitoring apparatus, equipment centralization, systematization can not damage various check implements and information transmission equipment concentrated controling management the co-platform modularized multi-function locomotive safety information comprehensive monitor system of the hardware and software of control monitor unit simultaneously again.
The objective of the invention is to realize by following technical proposals, between control monitor unit and various check implement and information transmission equipment, set up unified workplatform, various check implements and information transmission equipment are placed workplatform with the standard feature modular unit.Total system is except that power subsystem unit, and all the other each unit all have the multicomputer system of multistage serial communication.System adopts the multicomputer serial communication mode to control, and in this workplatform a basic functional units, i.e. communication log unit is set.It obtains train running information from the serial communication bus between control monitor unit main frame and telltale on the one hand, simultaneously obtaining information is real-time transmitted to each functional module elements in the device by another grade communication, thereby does not influence any soft, the hardware of control monitor unit; Each functional module elements feedack of real time recording again on the other hand.The inner mode of operation of taking by the power subsystem unit centrally connected power supply of device, the circuit and the associated external equipment (as: sensor, locomotive label etc.) thereof that provide multiple power supplies to export to each unit by power subsystem unit.Each unit therefrom selects for use any power supply all must take mode and system power supply isolation such as DC-DC changer, to improve the functional reliability of system power supply.The communication log unit is the core of device, obtains the operation information of control monitor unit by it, finishes the information of each functional unit feedback information and the dump of outbound data.Each unit plug-in unit adopts 48 unified core plugs in the device, by 48 core sockets on the motherboard in the case and track each unit is linked to each other.
Principal feature of the present invention is:
(1) adopt 4U standard PC case and bound cell mode to carry out structure design.So both meet the requirement of open workplatform structure, also be convenient to normalisation, the modularization of device, helped Device Testing, maintenance, function expansion and standardized administration.
(2) adopt separate multistage serial communication mode exchange message.So both can guarantee not influence original hardware and software of control monitor unit, improve real-time, availability and the unitarity of record data again.
(3) adopt the data record format compatible fully with engine monitoring apparatus.Can make full use of the dump of original control monitor unit and Ground analysis equipment like this and analyze data with management accounts, save investment.
(4) adopt advanced flash memory technology.Like this can be without battery, and record data can preserve (more than 10 years) for a long time, have improved reliability of data storage simultaneously.
(5) each functional unit adopts isolation technology in the device.Isolate and external input/output signal isolation technology as isolated from power, communication interface, improved reliability, safety and the anti-interference resistance of device.
(6) device is the open platform structure, and each functional unit adopts unified hardware specification and soft communication agreement.Help the cooperative development of functional unit and the expansion of what's new like this.
The invention will be further described below in conjunction with drawings and Examples
