The groundwork of this invention is, carrying out the intelligence grading by the status data to the vehicle critical component handles, the fault of vehicle is divided into elementary (also promptly by driver or ground remote control with regard to soluble fault), region class (also promptly cooperating soluble fault by the certain region resource of driver and ground), centre grade (also promptly cooperating just soluble fault by the more resources of driver and center, ground), corresponding the vehicle working condition on-line monitoring system mainly is divided into vehicle-mounted, regional, center and four parts of network communication transmission system transmission network; Status data can send to ground by the vehicle-ground wireless communication transmission system, thereby can realize that different fault types can be in the timely and effective solution in only place, and realizes the networking of monitoring system and in linearize.Basic process is, handle by the status data of gathering from the critical component of each vehicle being carried out uniform data, then, in vehicle-mounted rank, pick out and to operate primary fault (for example switching to the blocked operation of stand-by facility etc.) that onboard system just can in time solve and information is sent to driver information display system prompting driver operation by vehicle drivers by pretreatment, so that in time solve primary fault; Each vehicle is connected with ground communication by the vehicle-ground wireless communication transmission system of network communication transmission system, thereby can be transferred to ground to the status data of vehicle part, handles to carry out senior monitoring; The area information processor processing is handled information, judges this zone (as the zone, station) the manageable vehicle trouble and the indication of dealing with; Central information disposal system ground, ground central information treater exercises supervision to the operation of whole working condition system, and is responsible for finishing the processing of two burdensome fault contents of rank in the total system zone, above.Simultaneously, at centre grade data base management system and vehicle-state intelligent decision device are set in case of necessity,, vehicle are made fault pre-alarming according to data base management system institute's stored history and current data, in conjunction with carrying out analysis and judgment.
Figure 2 shows that the vehicle working condition on-line monitoring system embodiment scheme drawing of track traffic provided by the present invention.Among this embodiment, the monitoring of working condition system applies is in the daily operation of urban track traffic, and its purpose is the operation conditions of real-time monitor vehicle (perhaps train), and in time instructs the failure problems that solves vehicle, improves track traffic reliability of operation and safety.
With reference to shown in Figure 2, the vehicle working condition on-line monitoring system of this embodiment track traffic comprises vehicle data acquisition module 10, compound sensor 21, vehicle-mounted work information pretreater 22, driver information display system 23, vehicle-ground wireless communication transmission system 30, ground central information treater 51 and area information treater 421,422.Wherein, vehicle data acquisition module 10 is positioned on each Vehicular system; Compound sensor 21, vehicle-mounted work information pretreater 22, driver information display system 23 are positioned on each onboard system, and vehicle-mounted work information pretreater 22 is connected with the driver information display system; Ground central information treater 51 and area information treater 421,422 are arranged in ground system; Equipment such as the compound sensor 21 in the onboard system, vehicle-mounted work information pretreater 22, driver information display system 23 are with In-vehicle networking telecommunication transmission system transmission state data; Equipment such as ground central information treater 51 in the ground system and area information treater 421,422 are by 52 transmission state data and the orders of ground network telecommunication transmission system.Ground network telecommunication transmission system 52, vehicle-ground wireless communication transmission system, In-vehicle networking telecommunication transmission system (not shown among Fig. 2) are formed the network communication transmission system of this on-line operating condition monitoring system jointly.
See also Fig. 2, the vehicle critical component status data when vehicle data acquisition module 10 is used for the operation of real-time collection vehicle.The vehicle critical component is the equipment important relatively to the reliability of vehicle operating, those skilled in the art can be according to the particular case of each vehicle, select parts different on the vehicle as the vehicle critical component, generally, with the relative important components that can react running conditions of vehicle in the vehicle operating process as the vehicle critical component.In this embodiment, the vehicle critical component includes traction system, brake system, central control system, auxilliary inverse system, walking system, train network system, a/c system and door device etc., but should be understood that, the vehicle critical component is not limited to these, for example, can also comprise cab signal system etc.Be to be understood that simultaneously a vehicle has two or more vehicle data acquisition module 10.In this embodiment, vehicle data acquisition module 10 concrete structure examples as shown in Figure 3.
Figure 3 shows that the structure example scheme drawing of vehicle data acquisition module 10.As shown in Figure 3, in this example, the critical component of data acquisition comprises traction system, brake system, central control system, auxilliary inverse system, a/c system and door device etc., each critical component is directly corresponding to be connected with a first order sensor, the initial condition data of each critical component of first order sensor acquisition, because the variety of critical component, cause the variety of the data manifestation that collects, perhaps be the isomery type.Then, the status information transmission of each primary sensor collection is to compound sensor.Can see that above embodiment is the distributed collection mode, promptly from the direct acquisition system equipment operation condition of the network data of the sensor of each critical component.Those skilled in the art it is also understood that, can also adopt and concentrate the pattern of gathering, i.e. " black box " collection vehicle system core parts health data from existing On-Board Diagnostics (OBD) network.
Continue as shown in Figure 2, vehicle critical component status data when compound sensor 21 receives the vehicle operating that vehicle working condition data acquisition modules 10 transmit, these status datas can be cached in 21 the buffer area of recombiner, by finish in the compound sensor 21 to pattern different, form is different, expression has other isomerized data to carry out the isomorphism processing, data after the isomorphismization are convenient to carry out analyzing and processing, are convenient to multiple connection/tap and transmission.Compound sensor further carries out the data coding and transmits and handle then.
Continue as shown in Figure 2, vehicle-mounted work information pretreater 22 receives the status data that compound sensor 21 sends over, and this status data is handled through compound sensor 21 isomorphismizations, coding.Status data at first is stored in the buffer memory in the vehicle-mounted work information pretreater 22, waits pending processing.Vehicle-mounted work information pretreater 22 at first carries out elementary grading to status data to be handled.Because the huge property and the complexity of data, if in vehicle-mounted work information pretreater 22, carry out detailed data grading and carry out complete fault analysis and handling, requirement to vehicle-mounted work information pretreater improves greatly so, its system complexity also will improve, and, the more important thing is, these treating processs often need long wait, thereby can diminish the promptness of the information process analysis of vehicle-mounted work information pretreater 22.Can be to need vehicle-mounted work information pretreater 22 judge indication at once by rapid faults that solves such as driver operations particularly for those.Therefore here, elementary grading is handled and is meant carrying out preliminary classification in the status data, basically the status data of controlling the fault that just can at once handle by the driver is classified out.For example power supply bad contact, car door do not close primary faults such as tight.In a certain example, can be rated two classes to status data, when status data is the primary fault data greater than first threshold, when being less than or equal to second threshold value; Other then is non-primary fault data.This first threshold, second threshold value concrete selected can be set according to the different vehicle situation, for the status data type of critical component not, also can set different first thresholds, second threshold value.After being handled by grading, the primary fault data are further done information analysis, to extract failure message, in this information analysis process, can use data handling procedures such as comprising statistical analysis, generally speaking, because fault is elementary relatively, the information analysis process is also fast simple relatively.Further, the result makes information processing according to information analysis, for example, sends information processing and indicates to driver information display system 23 so that the driver makes the corresponding operating of trouble-shooting fast.In addition, also can send the information processing of alarm message, the indication of reporting to the police (blueness that for example corresponding fault rank is lower is reported to the police) can send to annunciator included in the vehicle mounted failure pretreater 22.Should be appreciated that the elementary grading of data is not limited to the grading of the two-stage classification in this example, need as the case may be, can carry out the grading of the above classification of two-stage or two-stage and handle.
Continue as shown in Figure 2, the status data of compound sensor 21 can further send to vehicle-ground wireless communication transmission system 30 through behind the vehicle-mounted work information pretreater 22.General run of thins, the data that all compound sensors 21 are sent all can transfer to ground by ground wireless communication transmission system 30 again.In this embodiment, ground wireless communication transmission system 30 comprises the vehicle-carrying communication adapter 31 in the onboard system and the ground communication adapter 32 of ground system, also comprises vehicle-mounted transceiver and ground-based transceiver (not shown) in addition.Described status data is sent to vehicle-carrying communication adapter 31 through vehicle-mounted work information pretreater 22, vehicle-carrying communication adapter 31 can carry out handling for the further coding that radio communication is implemented to status data, and same ground communication adapter 32 can be handled the corresponding decoding that status data carries out implementing for radio communication.Wherein 33 is the vehicle-ground wireless communication transmission channel.Status data in time can be sent to ground by vehicle-ground wireless communication transmission system 30, handle so that ground-surface other system carries out timely information analysis.In addition, the status data of a plurality of vehicles can transfer to ground by vehicle-ground wireless communication transmission system 30, thereby can realize In-vehicle networking telecommunication transmission system, the ground network telecommunication transmission system in the vehicle working condition on-line monitoring system, the network integration of vehicle-ground wireless communication transmission system.Be appreciated that also that in addition some directive commands that transmit from the ground network telecommunication transmission system etc. also can transfer to the In-vehicle networking telecommunication transmission system by vehicle-ground wireless communication transmission system 30.
Continue as shown in Figure 2, the ground communication adapter 32 of vehicle-ground wireless communication transmission system 30 can be by In-vehicle networking telecommunication transmission system 52 transmission state data to the area information treater, and this status data is handled through compound sensor 21 isomorphismizations and coding.The area information treater is used to be in charge of the region class analyzing and processing in some zones, and for example, as the case may be, this zone can be defined as a station, also can be for being defined as several stations.Status data at first is stored in the buffer area of area information treater, waits for data handing.The area information treater at first carries out secondary grading to status data to be handled.Here it is that elementary relatively grading is handled that secondary grading is handled.The area information treater will be carried out vehicle-mounted relatively work information pretreater 22 more premium-quality information analyses and handle, therefore, the area information treater can further carry out intermediate data grading with reference to the elementary rating result of the data of vehicle-mounted work information pretreater 22, and the pairing status data of the manageable failure message of area information treater is classified out.In a certain example, can be to the processing of further grading of above-described non-primary fault data, when non-primary fault data are the region class fault data greater than second threshold value, when being less than or equal to the 3rd threshold value; Other then is non-region class fault data.This second threshold value, the 3rd threshold value concrete selected can be set according to the different vehicle situation, for the status data of critical component not, also can set the second different threshold values, the 3rd threshold value.
After secondary grading processing, the region class fault data further done information analysis, to extract failure message, in this information analysis process, can use data handling procedures such as comprising data mining, data fusion, generally speaking, because fault is region class relatively, the information analysis process relatively can be too not complicated, so the region class fault also can in time be solved.Further, the result makes information processing according to information analysis, for example, send the information trouble removal handle indication (for example comprising concrete fault type, the corresponding clearing of a fault pretreating scheme of institute) to the staff (for example station staff) in the institute corresponding region so that carry out carrying out the work of preparing in advance before the trouble removal for the fault vehicle sails the station into.Here, the region class fault mainly be meant outside those primary faults, can wait regional center to separate the decision fault type rapidly AT STATION, for example, by changing the soluble fault of a certain miniature parts.Should be appreciated that concrete region class fault can define according to the different trouble removal ability of regional center.In addition, the area information treater also can send the information processing of alarm message, the indication of reporting to the police (for example only being higher than blue yellow alarm of reporting to the police) can send in the area information treater included or vehicle-mounted in included annunciator.Should be appreciated that the region class grading of data is not limited to the grading of the two-stage classification in this example, needs as the case may be, can carry out the grading of the above classification of two-stage or two-stage and handle.In other example, can be not yet with reference to the elementary grading result of vehicle-mounted work information pretreater.
In embodiment illustrated in fig. 2, two area information treaters have schematically been provided, area information treater 1 and area information treater 2 422 should be appreciated that the vehicle working condition on-line monitoring system can be provided with two or more a plurality of area information treater.In this embodiment, the vehicle working condition on-line monitoring system comprises that also area information represents device, area information represents that device 1, area information represent that device 2 422 is connected with area information treater 2 422 with area information treater 1 respectively, the result of the regional information treater that is used to show that this is regional.
Continue as shown in Figure 2, the ground communication adapter 32 of vehicle-ground wireless communication transmission system 30 can be by ground network telecommunication transmission system 52 transmission state data to ground central information treater 51, and this status data is the data through compound sensor 21 isomorphismizations and coding processing.Ground central information treater 51 is highest level systems of this vehicle working condition on-line monitoring system, and it can carry out failure analysis, trouble removal and failure prediction or the like to all vehicles in the whole vehicle working condition on-line monitoring system.In this embodiment, ground central information treater 51 communicates to connect with ground network telecommunication transmission system 52.Ground network telecommunication transmission system 52 can be transmitted in ground network telecommunication transmission system 52 after receiving the status data that ground communication adapter 32 sends over.For example in this embodiment, the area information treater also is to communicate to connect with ground network telecommunication transmission system 52, and ground network telecommunication transmission system 52 received status datas can be sent to area information treater or ground central information treater 51.Status data can at first be stored in the buffer area of ground central information treater 51, waits for data handing.Ground central information treater 51 at first carries out level grading at end to status data to be handled.Here, level grading processing is that secondary relatively grading is handled, elementary grading is handled eventually.All vehicle-mounted work information pretreaters 21, area information treater can not analyze the fault of eliminating, might get rid of by in vehicle-state monitoring intelligent decision device 51, obtaining analyzing.Vehicle-state monitoring intelligent decision device 51 will be carried out than the more premium-quality information analysis of area information treater and handle, therefore, ground central information treater 51 can the reference zone message handler the secondary rating result of data, further to carry out level data grading at end, the pairing data of ground central information treater 51 manageable failure messages classified out.In a certain example, can be to the processing of further grading of above-described non-region class fault data, when non-region class fault data is non-central level fault data during less than the 3rd threshold value; When non-district level fault data is the centre grade fault data during more than or equal to the 3rd threshold value.The 3rd threshold value concrete selected can be set according to the different vehicle situation, for the status data of critical component not, also can set the 3rd different threshold values.
After the level grading is handled eventually, the centre grade fault data further done information analysis, to extract failure message, in this information analysis process, can use data processing techniques such as comprising data analysis, data mining, data fusion, because fault is centre grade relatively, information analysis process relative complex, so the time course of information analysis may be longer relatively.Further, the result makes information processing according to information analysis, and this information process is mainly: judge the concrete fault type of concrete critical component according to the information analysis result, and provide the exclusion program of corresponding failure type.For example, sending information trouble removal processing prescheme carries out to prepare in advance for the staff (for example station staff) of the fault detection servicing center at center, ground before the troubleshooting effort of fault vehicle so that be.In addition, if for some fault type, vehicle-state monitoring intelligent decision device 51 can not provide the trouble removal scheme, also can manually provide the exclusion program of fault type by the staff.In this embodiment, the centre grade fault is generally relatively large, not recurrent vehicle trouble, therefore the processing time is longer relatively, but in this monitoring system, can fully use the fault analysis and handling ability of ground central information treater, the centre grade fault can obtain unified processing effectively.Should be appreciated that equally concrete centre grade fault can define according to the different trouble removal ability of ground central information treater 51.The information processing that ground central information treater 51 can send alarm message, the indication (for example being higher than the orange warning of yellow alarm) of reporting to the police can send included annunciator in the central information treater 51 of ground.
Further, during the whole level grading of the data of ground central information treater 51 is handled, can also set the 4th threshold value grades to the centre grade fault data, if the centre grade fault data is greater than the 4th threshold value, then vehicle trouble is huge, ground central information treater 51 also can't carry out trouble removal, needs directly vehicle system out of service to be keeped in repair, for example back shop.At this moment, the information processing that ground central information treater 51 sends alarm message, the indication (for example five-star red alarm) of reporting to the police can send included annunciator in the central information treater 51 of ground.Certainly driver information display system 23 also can receive the analysis processing result of ground central information treater 51, area information treater, so that driver operation.
In addition, ground central information treater 51 also communicates to connect with exterior Rail Transit System control center, can realize communicating to connect between vehicle working condition on-line monitoring system and the Rail Transit System control center, to realize mutual coordination between the two.
