Description
Technical Field
The utility model relates to the technical field of rail transit, in particular to a method and a system for positioning a parking row position of a motor train unit.
Background
The existing motor train unit position tracking system realizes the positioning and tracking of the motor train unit based on the occupation and the clearing of the track circuit, and the positioning precision is only a single track circuit section. Along with the increase of the running quantity of the motor train units, the motor train sections (units) are forced to store pressure, a plurality of motor train units are often parked on a stock track through setting up a parking mark, and at the moment, the motor train unit position tracking system cannot automatically and accurately position the train units; specific: the motor train unit position tracking system and the computer interlocking system interface acquire the representation information of the station yard, track the moving track of the vehicle in real time according to the conditions of section occupation, route locking, annunciator display and the like contained in the representation information, and therefore the position of the motor train unit in the station yard is judged. However, in the above scheme, the positioning accuracy can only be accurate to the section, the accurate train position of the train set on the section cannot be resolved, and the system is limited by the tracking principle, so that the train set position on the electroless section cannot be analyzed and positioned. Due to the problems of the scheme, in the actual operation process, a station operator and a driver are required to control in a combined mode, the parking position is marked manually, the workload of the operator is increased, and the safety risk exists in the subsequent shunting.
With the construction of inter-city (urban) railways, the running quantity of small-group motor train units is greatly improved, and the situation that a plurality of motor train units are parked on one track section is more common, so that the technology for improving the automatic positioning precision of the train positions of the motor train units is necessary to be researched, the accurate tracking of the positions of the motor train units is completed, and the operation safety is further ensured. At present, the following two schemes are mainly proposed:
scheme one: the existing motor train unit positioning processing method is similar to that in a maintenance warehouse line of a motor train section. And taking a temporary repair warehouse on a stock way where the repair warehouse line is positioned as a center, respectively installing infrared detection equipment on the I row position and the II row position of the repair warehouse, and determining the parking row position of the motor train unit by collecting the occupation and clearing states of the infrared detection equipment to identify the row position. For example, the chinese patent of the utility model, "a system for determining the position of a motor train unit in an inspection warehouse in real time," issued with CN206475890U adopts a technique similar to scheme one.
However, the disadvantage of scheme one is that: (1) The method can only be applied to maintenance warehouse lines, is limited by the deployment mode of the acquisition equipment (the acquisition equipment needs to be installed on a two-layer working platform), and cannot be applied to stock tracks of a parking lot. (2) Only the position of a single short-range motor train unit (8-range) can be analyzed and judged, and the method is not applicable to scenes in which a plurality of motor train units are stored. (3) Limited by the principle of the acquisition equipment, the running situation of the motor train unit cannot be identified, and erroneous judgment is easy to generate when an obstacle shields the running situation. (4) The required collection equipment quantity is more, and the equipment quantity of each row position needs to be more than or equal to 4, and later maintenance management is inconvenient.
Scheme II: the axle counting track circuit is used for detecting and comparing the wheel axle numbers of the wheels of the train entering and leaving the track section and judging the idle and occupied states of the corresponding track section. For example, chinese patent publication number CN201268315Y, axle counting track circuit. The basic working principle is based on the comparison result of the recorded axle number when the train (vehicle) enters and exits the section monitored by the axle counting point, so as to determine the occupied or idle state of the section. When a train enters from one end of the checked section and the wheels drive into the action area of the axle counting sensor, axle pulses are transmitted to the counting unit, the counting unit starts counting, the running direction is judged, and whether the axle number is counted up or counted down is determined. At the moment, the counting result at the other end is zero, and the track plate sends out section occupation information according to the shaft number information after being inconsistent, so as to control the section track relay to fall. When the train passes through the other end, the axle counting sensor counts, the axle number of the display section of the display unit is reduced through the comparison of the track plates, and when the axle numbers of the two ends are consistent, the track plates output section idle information, so that section idle and occupied state detection is realized. And on the basis, judging the parking column position (or the parking position) of the train set on the section by the method of the scheme one.
However, in the second scheme, the number of acquisition devices is large, and the number of devices in each column is 4 or more, which is inconvenient for later maintenance and management.

In the embodiment of the utility model, the identity and the position information of the motor train unit are acquired through an interface with a motor train unit position tracking system.
In the embodiment of the utility model, the identity and position information of the motor train unit comprises: the number, model and grouping of the motor train unit, the position, running direction and the moment of entering into the stock way. Wherein: the motor train unit model number plus the train number (such as CRH 2A-5001) is a unique identifier of the motor train unit and is used for management and external interaction of the motor train unit in software. The position of the motor train unit refers to the running track of the motor train unit, and is mainly used for judging and distinguishing the actual occupied tracks of the motor train unit (a plurality of tracks are usually arranged in a station yard); the moment of entering the stock way mainly indicates that when the whole train of the motor train unit completely enters the stock way, the axle number information of the axle counting sensor is collected and triggered to enter the subsequent positioning logic; the type of the motor train unit can assist in judging the grouping type of the motor train unit, such as CRH380AL, which is certainly a long-length motor train unit, but when in actual implementation, grouping information is generally directly used for logic processing; the grouping information includes grouping types (e.g., 4, 8, 16, etc.) of the motor train units; the running direction indicates the moving direction of the motor train unit.
The preferred embodiment of this step is as follows:
(1) And determining the train position of the stock track initially occupied by the motor train unit according to the shape direction of the motor train unit and the basic information, and determining the train position of the head and the tail of the motor train unit after the motor train unit is stopped by combining the model and the grouping.

In order to more clearly demonstrate the technical scheme and the technical effects provided by the utility model, the method provided by the embodiment of the utility model is described in detail below by using specific embodiments.
1. Summary of the principles.
The axle counting sensor consists of a magnetic head, a transmitter and a receiver, and when the axle of the motor train unit passes over the axle counting sensor, different electric pulse signals are triggered to be generated, so that the detection of the axle number of the passing wheels and the judgment of the running direction are realized. Because the number of wheel pairs of the motor train unit is fixed, the motor train unit is only related to the grouping type (for example, 4 groups of wheel pairs are grouped into 16 groups of wheel pairs, 8 groups of wheel pairs are grouped into 32 groups of wheel pairs, and 16 groups of wheel pairs are grouped into 64 wheel pairs).
The utility model utilizes the characteristic of the axle sensor and combines the information of the stock condition of the stock track, the grouping type of the motor train unit, the deployment position of the axle counting sensor and the like to identify the position of the specific train position of the motor train unit in the stock track. Specific: the axle counting sensor acquires axle number information by sensing the magnetic field change when the wheels pass through the axle counting sensor, respectively records the passing axle number according to the in-out direction and the in-out direction, and can acquire information of entering the stock way and the train position of the motor train unit by combining station field representation information. When the motor train unit enters the stock way, the stock way and the entering direction of the motor train unit can be judged according to the station yard representation information. The axle counting sensor is arranged near a stop mark between two train positions which need to be distinguished on a track, and when the motor train unit runs between the train positions, the wheels trigger the axle counting sensor to count.
As shown in fig. 2, an example of the deployment of the axle counting sensor is illustrated. And the acquisition and transmission of the position information of the motor train unit are realized through equipment such as a shaft counting sensor, a rail side cabinet and the like. The axle counting sensor is arranged on a steel rail at one side of the stock way, and can detect the running direction of the motor train unit and the number of passing wheel pairs. The rail side cabinet contains information acquisition board, power and network equipment, and the information acquisition board is used for acquireing the information that the axle counting sensor sent, then passes through network equipment and conveys to upper strata application server (computer lab application server). In fig. 2, H224 is an H224 junction box; the axle counting represents a corresponding axle counting sensor, and the numbers at the rear are the numbers of the axle counting sensors; the connection line of the axle counting and the H224 is a sensor signal line, the connection line of the H224 and the rail side cabinet represents a signal cable, and the connection line of the rail side cabinet and the machine room application server represents an armored optical cable. Of course, the deployment scenario of fig. 2 is merely an example, and in practical applications, the actual deployment may be performed empirically by the user.
As shown in fig. 3, a row of stations (about 250 meters in length) on the track can accommodate parking an 8-gram train. Because the number of the wheel pairs of each motor train unit is fixed (related to the grouping type, for example, 32 groups of wheel pairs are 8 groups of wheel pairs are 16 groups of wheel pairs are 64 groups of wheel pairs), when the axle counting equipment detects that the axle number passing through the axle counting sensor is 32 for 8 groups of motor train units stored on a stock way, the whole row of motor train units can be judged to pass through the position where the axle counting sensor is located, namely, adjacent row positions are entered; for 16 motor train units, when the count reaches 64, the motor train unit can be judged to completely drive away from the existing area.
The effective length of the tracks used for storing the motor train unit in the motor train unit is about 500 meters, and generally, one track stores 2 short-line or 1 long-line motor train units, and for some special tracks, the length can reach about 1000 meters, the capacity is larger, and the parking condition of the motor train unit is more complex. The axle counting sensor can be arranged at the boundary position of two train track positions, and when the motor train unit runs between the train track positions, the axle counting sensor can be triggered to count. The number of wheel pairs which pass through in the running direction of the motor train unit is obtained by calculating the counting of the shaft sensors, whether the motor train unit completely passes over is judged, and accurate position analysis and positioning of the motor train unit in a stock way are realized.
2. And (3) positioning the parking row position of the motor train unit.
As shown in fig. 4, the relationship between the external system and the device according to the present utility model is shown, and on the one hand, the system interfaces with the external system (the train unit position tracking system) to obtain the identity and position information of the train unit in the yard. On the other hand, the axle number information of the running of the motor train unit acquired by the axle counting sensor is acquired by an interface of the axle counting sensor equipment, and logic judgment processing is carried out on the basis of the axle number information.
1. And establishing mapping and connection relations among the stock tracks, the row positions and the axle counting sensors.
As shown in fig. 5, after installing and disposing the axle counting sensors on the strand (strand object T) with the column position division according to the station situation, numbering each axle counting sensor, establishing the mapping and connection relation among the strand, the column position and the axle counting sensors, and storing the information records as basic information. During operation, the stored basic information is read, and the position information of the motor train unit and the counting information of the axle counting sensor are processed.
2. And acquiring the identity and position information of the motor train unit.
The motor train unit position tracking system can identify the information such as the vehicle type, the vehicle unit number, the marshalling and the like of the motor train unit, acquire the running track of the train through logic operation, and realize continuous tracking of the motor train unit position. The utility model acquires the identity and the position information of a motor train unit by means of an interface with a motor train unit position tracking system, and as shown in fig. 6, the motor train unit position tracking system mainly comprises a motor train unit number, a motor train unit model number, a motor train unit grouping, a motor train unit position, a running direction and a time of entering a stock track, and when the motor train unit enters the stock track, a processing object of the motor train unit is created according to the information, namely a motor train unit object E.
3. And judging the initial train position of the motor train unit and acquiring the reference axle number information.
(1) Mapping relation between short-woven car group and column bit.
According to the generated motor train unit object E, the initial position of the motor train unit on the stock way and the axle number information of the corresponding axle counting sensor can be obtained. As shown in fig. 7, when one motor train unit object E enters from the right side of the track, the initial occupied train position is the rightmost train position of the track, and in combination with the train group type (assumed to be 8 trains) of the motor train unit object E, after the motor train unit object E is stopped, the train heads and the train tails are all on the train position n of the track, at this time, the current shaft numbers of the shaft counting sensors (the shaft counting n-1) adjacent to the left side of the train position n are recorded as the reference shaft numbers, and finally, the mapping relationship between the motor train unit object E and the train position of the track is established so as to acquire the train storage information of the train position. As shown in fig. 8, the motor train unit object E occupies only one column position, that is, the left end and the right end of the motor train unit are both directed to column position n, and column position n is directed to the motor train unit object E.
(2) Mapping relation between long-coded train and column bit.
As shown in fig. 9, when one motor train unit object E enters from the left side of the track, the initial occupied column position is the leftmost column position of the track, and in combination with the grouping type (assumed to be 16 groups) of the motor train unit object E, it is known that two column positions are occupied after the motor train unit object E is stopped, that is, the left end of the motor train unit is at column position 1 of the track, the right end of the motor train unit object E is at column position 2 of the track, and at this time, the current shaft number of the shaft counting sensor (shaft counting 2) adjacent to the right side of the column position 2 is recorded as the reference shaft number. Finally, a mapping relation between the motor train unit object E and the stock track train position is established, as shown in fig. 10, the train unit object E occupies 2 train positions, namely, the left end of the train unit points to the train position 1, the right end points to the train position 2, and the train position 1 and the train position 2 point to the train unit E.
4. And judging the position of the train set based on the initial train position and the reference shaft number.
When the motor train unit walks across the train position, the relative axle counting sensor is triggered to count to change, and the position of the motor train unit can be judged by comparing the difference value between the real-time axle number of the corresponding axle counting sensor and the reference axle number. The utility model only processes the counting information of the axle counting sensor at the outer side of the row position occupied by the train unit object (namely, the front axle counting sensor in the running direction), as shown in fig. 9, when the train unit object E occupies two row positions, only processes the counting information of the axle counting 2, and as the left side and the right side of the axle counting 1 are in the occupied state, the logic judgment processing is not performed on the counting information of the axle counting 1.
In the embodiment of the utility model, the running direction of the motor train unit is usually one direction in default; for example, the forward direction is the shape direction, and the front log sensor in the forward direction is used for subsequent logic judgment; of course, it is also possible that the current motor train unit is in the middle row position, and it can go forward continuously or backward, and the default situation is the same when going forward continuously, and when backward, the backward direction is the shape direction, and the front axle counting sensor in the backward direction will be used for subsequent logic judgment.
As described above, the present utility model is applicable to a scenario in which a plurality of motor train units are stored, and the following description will be made with respect to a scenario in which a single motor train unit and a plurality of motor train units are separately illustrated.
(1) Only one motor train unit object running scene exists in the stock way.
As shown in fig. 11, when the train unit object E enters from the left side of the track, the initial row position is row position 1, and the current count information of the axle counter 1 is acquired and set as the reference axle number (left reference axle number Lb and right reference axle number Rb) according to the connection relation between the row position and the axle counter sensor. In the process that the train unit runs from the row position 1 to the row position 2, the right row count R1 of the axle counting 1 is increased, when the R1 is increased by 32 (compared with the reference count Rb), the train unit can be judged to completely enter the 2 row positions, the initial row position of the train unit object E is updated to the row position 2, meanwhile, the mapping relation between the row position and the train unit object E is reset, the real-time counts L2 and R2 of the axle counting 2 are set as the reference axle numbers, and the specific implementation flow is shown in the figure 12.
(2) There are multiple scenes in the track where the motor train unit objects walk.
When a plurality of motor train unit objects exist in the stock way, if a certain train position is occupied by a driven motor train unit object, other motor train unit objects can not enter the stock way. For example, as shown in fig. 13, a train unit object E1 (group type 16) occupies a column position 2 and a column position 3, and a train unit object E2 occupies a column position 4. In this case, since the motor train units are parked on the left and right side row positions of the counter shaft 2 and the counter shaft 3, the information of the sensors of the counter shaft 2 and the counter shaft 3 is not processed any more, and only the count information of the counter shaft 1 is processed. When the left row count L1 of the gauge shaft 1 is increased by 32 (compared with the reference count Lb), it can be considered that the train unit object E1 left-proceeds to the train position 1, as shown in fig. 14, it can be judged in combination with the grouping type of the train unit object E1 that the train unit object E1 leaves the train position 3, so that the position of the train unit object E1 is updated to the train position 1 and the train position 2, the mapping relation between the train position and the train unit object E1 is reset, and the real-time counts L2 and R2 of the gauge shaft 2 are set as the reference shaft number. The concrete implementation flow is shown in fig. 15.
It should be noted that, in the above scenario example, only counting in a single direction of the axle counting sensor is considered to determine a train position where the motor train unit is located; however, in practical application, the counting in the other direction is collected as an abnormal condition for protection.
