Operation management is handled unit 9 by CPU formations such as (Central Processing Unit), respectively constitutes the unit according to the railway vehicle operation management programming control of present embodiment, and obtains the needed various data of operation management, carries out operation in good time and handles.The main processing of operation management processing unit 9 is as follows: the gps signal that receives according to gps signal receiving element 6 calculates the gps data relevant with vehicle, grasp at the actual operating state that moves predetermined vehicle according to this gps data and operation tentation data, be used to support the operation management of chaufeur, therefore can remind the unusual generation in the operation in early days.
Then, the structure that the operation management that carries out foregoing processing is handled unit 9 describes.Operation management is handled unit 9 mainly by operation data obtaining section 91, gps signal obtaining section 92, gps data calculating part 93, systems inspection portion 94, gps signal receives number judging part 95, revise with data obtaining section 96, predict the distance calculation portion 97 of travelling, predicted position data computation portion 98, can not time of reception judging part 99, position data is judging part 100 relatively, correction is with position data employing portion 101, vehicle location employing portion 102, abnormal running judging part 103, data preservation portion 104 when unusual, the checkpoint arrives judging part 105, operation guiding efferent 106, operation actual achievement data preservation portion 107 and next route data judging part 108.
Operation obtains the needed various data elements of operation of vehicle with data obtaining section 91.Specifically, obtain route from route data memory cell 2 and determine position data, checkpoint location data and secondary checkpoint location data, and obtain the operation tentation data from operation tentation data memory cell 3.
Gps signal obtaining section 92 obtains the gps signal that gps signal receiving element 6 receives.In the present embodiment, obtain gps signal, offer gps data calculating part 93 then with 1 second interval.In addition, gps signal is made of the signal of the multiple information such as orbit information of the position with time information, expression gps satellite.
The gps signal that gps data calculating part 93 is obtained according to gps signal obtaining section 92 calculates the gps data that the absolute fix data relevant with vehicle, time data, speed per hour data, direct of travel data and altitude information etc. constitute.
Specifically, at first according to the time of reception in time information in the gps signal and the gps signal receiving element 6, calculating is in order to receive the time of advent that gps signal spends, according to the propagation speed of this time of advent and gps signal, calculate the distance between gps satellite and the gps signal receiving element 6.Because the distance of this distance and the position of receiving position that is connected gps signal receiving element 6 and gps satellite equates, so by the equation with two unknowns establishment of three variablees (latitude, longitude, highly) formation.Therefore, when the gps signal that receives more than 3, can calculate correct absolute fix data (latitude, longitude) and altitude information.In addition,, then height setting can be become steady state value,, also can calculate correct to a certain extent absolute fix data (latitude, longitude) even the reception number of gps signal is two if the height of hypothesis vehicle does not change substantially.On the other hand, the reception number of time data, speed per hour data and direct of travel data and gps signal is irrelevant, can obtain correct data all the time.
The running-active status of 94 pairs of railway vehicle operation management systems 1 of systems inspection portion is checked, comes detection failure.Specifically,, obtain the absolute fix data that latitude relevant with the departure place of vehicle and longitude data and gps data calculating part 93 calculate, judge whether both are consistent if when setting out.Then, if both unanimities then are judged as native system and normally move.On the other hand, in inconsistent situation or do not receive under the situation of gps signal, the route data mistake that reads from the 7 output expressions of operation guiding output unit or the misinformation of gps signal receiving element 6 faults.In addition, the latitude of departure place and longitude data can manually be imported by chaufeur when outbound, also can come automatically to determine latitude and longitude data by the title that is chosen in the predefined place of starting in route data and the operation tentation data.
In addition, in the present embodiment, even systems inspection portion 94 has in the process of moving, the also function of the running-active status of OBD (On-Board Diagnostics) native system.Specifically, obtain checkpoint location data and gps data, judge whether vehicle follows the trail of (trace) each checkpoint in order.Then, only when correctly following the trail of, be judged as the native system regular event.On the other hand, confirm to have when unusual output error message.
In addition, in the vehicle of present embodiment, be provided with the gyrosensor Sj in the orientation of measuring vehicle.Therefore, the systems inspection portion 94 of present embodiment judges according to the bearing data of the vehicle of being obtained by this gyrosensor Sj and the bearing data between the checkpoint whether both are consistent.Then, if both always, are judged as the native system regular event.On the other hand, if inconsistent, then output error message.In addition, according to the checkpoint location data, the bearing data between the calculating inspection point.
Gps signal receives the reception number that number judging part 95 is judged gps signal.As mentioned above, the precision of gps data along with the difference of the reception number of gps signal difference.Therefore, in the present embodiment,, carry out the correcting process of position data described later rightly according to the reception number of gps signal.
Revise and obtain needed data in the correcting process of vehicle position data with data obtaining section 96.In the present embodiment, obtain not long ago correction with position data, time data and speed per hour data from operation actual achievement data storage cell 4.Herein, correction not long ago with position data be meant the absolute fix data that calculate when the gps signal that receives more than 3 or the reception number of gps signal continue specified time be 2 absolute fix data when following when equating substantially with predicted position data described later these absolute fix data or this predicted position data in up-to-date data.That is, be the position of determining up-to-date vehicle location in the high vehicle location of reliability, in the present embodiment, with this position as correction position.
Prediction travel distance calculation portion 97 can't obtain the high vehicle location of reliability during, if calculate the prediction operating range that vehicle travels.Specifically, according to revising correction not long ago position data and the time data of obtaining with data obtaining section 96, calculate from revising the elapsed time that the starting position begins, according to the prediction operating range of this elapsed time and speed per hour data computation vehicle.
The predicted position of vehicle is calculated by predicted position data computation portion 98.Specifically, determine that by revising the route of obtaining with data obtaining section 96 position data determines the railway route, obtain along this route as the predicted position data and advanced and predict the latitude longitude of the predicted position of operating range from revising the starting position.
For example, when the prediction operating range is L, calculate to connect revise starting position and nearest bend and determine the 1st linear position of point, when the length of the 1st straight line is L when above, obtain on the 1st straight line from revising the advanced position of L, starting position as predicted position.On the other hand, in the length of described the 1st straight line during, calculate and connect the 2nd straight line that next bend determines that point and nearest bend are determined less than L.Then, obtain on the 2nd straight line, from the definite latitude longitude of putting the position of advanced [L-(length of the 1st straight line)] of nearest bend as the predicted position data.
Can not time of reception judging part 99 be to judge because through reasons such as blind areas, the reception number of gps signal is whether the state below 2 has continued specified time.In the present embodiment, set this time length for 5 seconds, but be not limited to this, can suitably set by the user, in addition, suppose that reception number at gps signal is the situation that state below 2 has passed through the checkpoint before through 5 seconds, can discern this moment near the checkpoint is positioned at, do not wait for that 5 seconds ground executes the correcting process of vehicle position data described later.
The predicted position data that absolute fix data that 100 pairs of gps data calculating parts 93 of position data comparison judging part calculate and predicted position data computation portion 98 calculate compare judgement.In the present embodiment, when the absolute fix data are positioned at the predicted position the effective scope of measuring the zone that to be benchmark set by the Effective width of stipulating, are judged to be the predicted position data and equate substantially with the absolute fix data.On the other hand, when the absolute fix data are outside the scope of effectively measuring the zone, these absolute fix data are considered as the off-square data.
Correction is used to revise the correction position data of the position data of vehicle with position data employing portion 101.Specifically, be three and the absolute fix data that gps data calculating part 93 calculates use position data as revising when above receiving reception number that number judging part 95 is judged as gps signal by gps signal, and be stored in and move in the actual achievement data storage cell 4.In addition, even when the reception number reduces to 2, also send correct location information sometimes.Therefore, by the reception number that can not time of reception judging part 99 be judged as gps signal be state below 2 continuous specified time, and be judged as the predicted position data when equating substantially with the absolute fix data by position data comparison judging part 100, these predicted position data or this absolute fix data are used data as revising, and be stored in the operation actual achievement data storage cell 4.
Vehicle location employing portion 102 obtains high absolute fix data of reliability or predicted position data as the position data of vehicle.Specifically, the absolute fix data that adopt with position data employing portion 101 or the predicted position data position data as vehicle will be revised.Therefore, in the present embodiment, the reception number of being not only gps signal is the situation more than 3, even receiving number is 2 when following, at this state continuance specified time, and under absolute fix data and the situation that the predicted position data equate substantially, some with in these absolute fix data or the predicted position data as vehicle position data.Even this is to have utilized when the reception number is 2, the error of absolute fix data is not necessarily big.
Abnormal running judging part 103 judges whether the operation conditions of vehicle is normal.Specifically, obtain operation tentation data and gps data, and compare both.Then, calculate deviation or the actual deviation of passing through speed and predetermined speed of passing through constantly and pass through predetermined instant in the reality of the checkpoint of stipulating, judge whether not above the allowed value of stipulating.
In addition, in the vehicle of present embodiment, be provided with the three dimension acceleration sensor Sa of the acceleration/accel of measuring three-dimensional.Abnormal running judging part 103 is obtained all the time from the acceleration simulation data of three dimension acceleration sensor Sa output, judges whether these data do not surpass the allowed value of the regulation of expression conventional operation scope.And, in the present embodiment, even under the situation that ATS (Automatic Train Stop) system moves, also detect the situation that anomalous behavior takes place in service at vehicle.
Data preservation portion 104 is when vehicle in service detects anomalous behavior when unusual, and data are kept at the unit in the abnormal data memory cell 5 during various unusual before and after this anomalous behavior is taken place.In the present embodiment, data storage image data, gps data and ATS data etc. when unusual.The image data that is photographed by operation conditions image unit 8 temporarily is stored in not shown video memory etc. successively, begins to delete in order from becoming data of a specified duration.Therefore, data preservation portion 104 is being detected by abnormal running judging part 103 when unusual when unusual, the generation that obtains this anomalous behavior constantly and obtains image data between the front and back two minutes in this generations moment from video memory, and is stored in the abnormal data memory cell 5.
The checkpoint arrives judging part 105 and judges whether vehicle has arrived the checkpoint.In the present embodiment, the checkpoint arrives the error that judging part 105 is considered vehicle position data, has set with cooresponding checkpoint, each checkpoint and has measured zone (hereinafter referred to as " CP measures the zone ").Then, in the time of in vehicle location is included in this CP mensuration zone, is judged as vehicle and has arrived this checkpoint.
Specifically, as shown in Figure 3, CP measures the zone and is made of following: with the position determined according to the checkpoint location data is benchmark (center), the cardinal principle of setting by the efficient range of regulation foursquare main measure the zone and with this master measure regional adjacent setting, be benchmark (center) with the position determined by secondary checkpoint data, the cardinal principle of setting by the efficient range of regulation foursquare secondary measure regional.Therefore, definite CP measured the zone after arrival judging part 105 in checkpoint was obtained checkpoint location data and secondary checkpoint location data from route data memory cell 2, and obtained by vehicle location and adopt the vehicle position datas of 102 employings and CP mensuration zone to compare.
In addition, the size that CP measures the zone it is desirable to set according to the speed of vehicle, in the present embodiment, suppose that vehicle travels with 60km/h (about 18m/s), measure the zone and the secondary zone of measuring is set square that a limit is 36m and two summits on route main.Therefore, in each measures zone, receive gps signal, therefore,, obtain obtaining at least 4 times the chance of gps signal for a checkpoint with about ± 1 second error limit.
Operation guiding efferent 106 is the unit to the operation guiding of operation guiding output unit 7 output regulations.Specifically, be judged as vehicle when having arrived the checkpoint of regulation, obtain and the cooresponding various information in this checkpoint from operation tentation data memory cell 3 when arrive judging part 105 by the checkpoint.Then, vehicle by loud speaker voice guide reality passes through the deviation of passing through predetermined instant of the moment for this checkpoint, the actual purport that speed changes for the deviation of predetermined speed, next bus stop or checkpoint title or limited speed etc. of passing through perhaps shows guiding in telltale.
Operation actual achievement data preservation portion 107 will move the actual achievement data and be kept in the operation actual achievement data storage cell 4.Specifically, be judged as vehicle when having arrived the terminal point in the fixed course arriving judging part 105 by the checkpoint, will be stored in the operation actual achievement data storage cell 4 at the gps data that passes through constantly, obtains of the vehicle of each checkpoint etc. by per second.
When next route data judging part 108 is through with the operation of a railway route at vehicle, judge in the operation tentation data whether have the railway route that then move.If the result who judges is when having the railway route that then move, then continue to make the railway vehicle operation management system 1 of present embodiment to carry out operation management, on the other hand, if there is not the railway route that then move, then make railway vehicle operation management system 1 end process.
Below, the effect of the railway vehicle operation management system of carrying out by the railway vehicle operation management program of present embodiment with reference to Fig. 4 and Fig. 5 explanation 1.
At first, when the railway vehicle operation management system 1 by present embodiment begins the operation management of vehicle, the operation that route is taken in corresponding chaufeur input, operation obtains route data relevant with the railway route of this vehicle operating and operation tentation data (step S1) with data obtaining section 91.Then, as gps signal obtaining section 92 (step S2) when gps signal receiving element 6 is obtained gps signal, calculate various gps datas (step S3) by gps data calculating part 93.According to this gps data and route data and operation tentation data, systems inspection portion 94 checks the running-active status (step S4) of railway vehicle operation management system 1.
If the result who checks is in system acting not unusual (step S4:OK), wait for that then the operation of vehicle begins (step S5); On the other hand, if find unfavorable condition (step S4:NG), then to operation guiding output unit 7 output error message (step S6).Thus, chaufeur can prevent to use wrong route data or operation tentation data, perhaps can prevent from not bring into play operational vehicle under the state of function at gps signal receiving element 6.
Then, when beginning the operation of vehicle (step S5:YES), during moving on the railway route by route data and operation tentation data regulation, obtain vehicle location (step S7) at any time by vehicle position data correcting process shown in Figure 5.
At this, the vehicle position data correcting process of using Fig. 5 explanation in step S7, to carry out.During vehicle operating, gps signal obtaining section 92 obtains gps signal (step S21) with about 1 second interval from gps signal receiving element 6, and gps data calculating part 93 calculates gps data (step S22) according to this gps signal.In addition, in the present embodiment, operation conditions image unit 8 begins to take in the operation beginning, and image data is stored in the video memory.
Then, gps signal receives number judging part 95 is judged the gps signal that receives in step S21 reception number (step S23), receiving number is 3 when above (step S23:YES), being judged as the absolute fix data that calculate in step S22 is high-precision data, enters among the step S29 described later.
On the other hand, at the reception number of gps signal is 2 when following (step S23:NO), at first, revise with data obtaining section 96 and obtain not long ago correction, predict the prediction operating range (step S25) of distance calculation portion 97 that travel according to these data computation vehicles with position data, time data and speed per hour data (step S24).Then, predicted position data computation portion 98 determines position data according to this prediction operating range and route, calculates the predicted position data (step S26) of vehicle.
Then, the reception number of the gps signal of judging in step S23 is 1 o'clock (step S27:NO), because therefore absolute fix data mal returns among the step S21, waits for receiving gps signal once more.On the other hand, be 2 o'clock (step S27:YES) at the reception number of gps signal, absolute fix may not mal.Therefore, when by can not time of reception judging part 99 have judged the reception number of gps signal be below 2 state continuance during specified time (step S28:YES), by position data relatively judging part 100 judge the homogeneity (step S29) of absolute fix data and predicted position data.
At this moment, in the present embodiment, the feature of utilizing railway vehicle to travel on the pre-determined route that is predetermined along the route between the definite point of adjacent bend, has been set effective mensuration zone of Rack.Then, according to effectively measuring in the zone whether detect the absolute fix data, judge the homogeneity of absolute fix data and predicted position data at this.Thus, the required calculation process of the judgement of both homogeneity is simplified, and alleviates the relatively load of judging part 100 of position data when keeping correctness.
Then, be to be judged as the absolute fix data when equating substantially (step S29:YES) in the judged result of position data comparison judging part 100 with the predicted position data, it is correct substantially to be estimated as these absolute fix data or this predicted position data.Therefore, some data wherein are adopted as to revise with position data employing portion 101 by correction uses position data, and is stored in the operation actual achievement data storage cell 4 (step S30).Adopt the predicted position data that calculate in the present embodiment in principle.Similarly, when the reception number of gps signal is 3 when above (step S23:YES), because therefore the accuracy height of the absolute fix data that calculate in step S22 uses position data with this absolute fix The data for revising, and be stored in the operation actual achievement data storage cell 4 (step S30).
Then, has precision in the scope of allowing as mentioned above by revising the absolute fix data that adopt with position data employing portion 101 or predicted position data, so, adopt (step S31) as vehicle position data by vehicle location employing portion 102.As previously discussed, the reception number that is not limited to gps signal is 3 when above, at the state continuance below 2 during specified time, because absolute fix data or predicted position data that reliability is high adopt as vehicle position data, so in the precision of the position data that keeps vehicle, improved the probability of obtaining of position data.
On the other hand, be state below 2 when continuing specified time (step S28:NO) at the reception number of gps signal, return among the step S21, wait for receiving gps signal once more.In addition, when having negated the homogeneity of absolute fix data and predicted position data (step S29:NO),, wait for receiving gps signal once more because the reliability of absolute fix data is low, thereby gets back among the step S21.
When having obtained vehicle position data by above-mentioned vehicle position data correcting process, the flow process of getting back to Fig. 4 once more.In step S8, abnormal running judging part 103 is judged the operation conditions of vehicle according to operation tentation data and gps data.Then, at the operation tentation data, only when vehicle normally moves (step S8:YES), handle entering into step S9 in the scope of the allowed value of regulation.On the other hand, when in the operation conditions of vehicle, identifying anomalous behavior (step S8:NO), image data and gps data before and after data preservation portion 104 takes place this anomalous behavior constantly when unusual are kept at back (step S10) in the abnormal data memory cell 5, make to handle to enter into step S9.Thus, preserve the data that front and back take place anomalous behavior automatically, be used to study the reason of this anomalous behavior, prevent to take place once more.
In addition, in the present embodiment, abnormal running judging part 103 irrespectively monitors the acceleration simulation data that obtain from three dimension acceleration sensor Sa all the time with operation tentation data, gps data, so can judge paroxysmal accident or vehicle abnormality that the relatively judgement by operating data and gps data may postpone immediately.Specifically, when the chaufeur emergency brake, when vehicle is pressed onto the foreign matter of placing on the line (stone of placement, round log, bicycle etc.) or owing under the situations such as the fitful wind vehicle tilts artificially, be created in the acceleration/accel of can't see in the conventional operation, therefore detect abnormal running.Thus, even taking place under the situation that chaufeur also is difficult to the abnormal accident reason discovered in advance, also preserve the data of this abnormal accident before and after taking place.
Then, in step S9, arrive judging part 105 by the checkpoint and judge whether vehicle has arrived certain checkpoint.In the present embodiment, detecting the vehicle position data that in step S7, obtains when having arrived CP and measuring in the zone, be judged as the checkpoint (step S9:YES) that vehicle has arrived setting in this CP measures the zone.So, use the CP of the efficient range with regulation to measure the zone and judges, therefore the omission that arrives of the vehicle in each checkpoint is surveyed and is reduced, and prevents to move mispriming.On the other hand, only when not arriving any one checkpoint (step S9:NO) returns among the step S7, and repetitive cycling is handled till arriving the checkpoint.
When being judged as vehicle when having arrived some checkpoints (step S9:YES), systems inspection portion 94 checks the running-active status (step S11) of native system according to the tracking situation of each checkpoint, the azimuth information of gyrosensor Sj.If the result of this inspection then enters step S12 for do not confirm unusual (step S11:OK) in the action of system.On the other hand, if confirm that unusual (step S11:NG) arranged, output error message (step S13) in operation guiding output unit.Thus, native system can make chaufeur, operation management person one side identify this fault and take suitable countermeasure then when contingency break down in the process of moving immediately.
If not unusual in native system, then operation guiding efferent 06 is from the operation guiding (step S12) of operation guiding output unit 7 output regulations.In the present embodiment, except the deviation of passing through predetermined instant passed through constantly for this checkpoint to the chaufeur voice guide reality of vehicle, outside the actual deviation of moving velocity for limited speed, also the purport that changes of next bus stop name of station of voice guide or limited speed etc. perhaps shows in telltale.
Then, as long as vehicle does not arrive the terminal point of operating railway route, repeat processing (step S14:NO) from step S7 to S12, when having arrived terminal point (step S14:YES), the various data storage that operation actual achievement data preservation portion 7 will obtain in operation management is handled are in operation actual achievement data storage cell 4 (step S15).Then, till about the whole railway route end of runs in the operation tentation data, next route data judging part 108 repeats the processing (step S15:YES) from step S1 to S15, about the whole railway route end of run of operation in the tentation data time (step S16:NO), the operation management of this railway vehicle operation management system finishes.
The specific embodiment of present embodiment then, is described.
