As shown in fig. 2, as a preferred embodiment of the present invention, the status information acquisition module 100 includes:
a travel time identification unit 1001 for: judging the travelling time period of the train according to the travelling speed information of the train and the distribution information of crowd in the carriage; or acquiring the travelling time period of the train according to the outbound time and the inbound time in the train schedule;

The preposed time period at least ensures that the instruction is issued in time when the advancing time period starts;
Further, the starting to issue the instruction to the corresponding carriage in the pre-period specifically includes:
s10: starting from a carriage at the non-head end and the tail end, synchronously sending indication instructions to two sides, wherein the indication instructions carry carriage number identification streams which are distributed at intervals; the distance of the interval distribution is at least one carriage; the carriage at the non-head end is preferably the middle carriage, namely, when the number of the carriages is even, one of the two middle carriages, and when the number of the carriages is odd, the carriage is the middle carriage;
S11: sequentially conveying instruction instructions to two sides according to the arrangement sequence of the carriage number identification streams, wherein each carriage corresponding to the carriage number identification streams stores a plurality of carriage numbers at adjacent positions of the two sides; in this way, the instruction sent from the carriages at the non-head and tail ends can not directly reach each carriage one by one, but indirectly reach the carriages corresponding to the carriage number identification flows which are distributed at intervals, so that the number of the carriages which directly establish communication connection with the carriages at the non-head and tail ends can be reduced on one hand, the number of main communication ports is reduced, the failure rate is reduced, and on the other hand, the length of a communication transmission route (compared with the length of a line which directly establishes communication connection with each carriage in the prior art) can be greatly shortened;
S12: after receiving the indication instruction, each carriage corresponding to the indication carriage number identification stream distributes the indication instruction to a plurality of carriages corresponding to carriage numbers at adjacent positions on two sides of the indication instruction. The carriages corresponding to the carriage numbers of the adjacent positions comprise carriages within a set range; because each carriage corresponding to the carriage number identification flow is relatively close to the carriage positions corresponding to the carriage numbers at the adjacent positions on the two sides of the carriage number identification flow, the carriage which is not in the head end and the tail end is not required to directly establish communication connection with each carriage, the length of a communication line is greatly shortened, and the communication line comprises a wireless line and/or a wired line.
For example, the number of cars in the interval distribution is identified as C3-C6-C9-C13, the non-head-tail car is MC7 (C represents the normal car, MC represents the middle car), then the adjacent car corresponding to C3 is: c1, C2, C4, C5; the adjacent cars corresponding to C6 are: c4, C5, C8; c9 corresponds to the adjacent car: c7, C8, C10, C11, C12; c13 corresponds to the adjacent car: c10, C11, C12. If a certain carriage receives the instruction from the same batch of two carriages, the instruction should be executed only once, and the arrangement of the partial overlapping issuing can also ensure that the omission of the issuing instruction is avoided as much as possible.
The communication between the cars in the present embodiment is understood to be communication between devices having a communication function corresponding to the cars, such as a communication terminal; a device having a communication function can be understood as a part of a vehicle cabin;
It can be understood that this embodiment provides a method capable of issuing an instruction to a corresponding carriage within a lead time, and implementing according to this method can ensure that the non-missing issuing of the instruction is ensured while the transmission route is as short as possible, and in addition, the feedback of the instruction and the issuing of the instruction are in reverse order, which will not be described in any more.
As shown in fig. 3, as a preferred embodiment of the present invention, the foreign matter distribution detection module 200 specifically includes:
an acquisition and comparison unit 2001 for: the method comprises the steps of obtaining original state information of a hidden characteristic area, and comparing the original state information with real-time state information, wherein the original state information is confirmed foreign object-free state information before departure;
A foreign matter distribution determination unit 2002 for: when detecting that the difference degree between the real-time state information and the original state information reaches a preset difference degree, judging that the hidden characteristic area is in a foreign matter distribution state.
When the embodiment is applied, as the original state information is the confirmed foreign object-free state information before departure, when the difference between the real-time state information and the original state information reaches the preset difference, the presence of foreign objects in the hidden characteristic area is indicated. The state information (including original state information and real-time state information) can be image information, and the corresponding preset difference degree is picture difference degree; the distance detection information may also be distance detection information, if the detection distance reaches a preset distance, the preset distance is smaller than a normal distance at the moment, which indicates that the foreign matter occupies part of the space, and the detection distance becomes smaller.
As a preferred embodiment of the present invention, the identifying the kind of the ectopic object specifically includes:
s20: comparing the real-time state information corresponding to the foreign matter distribution state with the pre-stored state information of the carriage part; considering that cabin components, particularly components within the cabin, may scatter into the feature area for some reasons, such as components on the seat, components on the window, etc., these components may interfere with the identification of the dropped items;
s21: and when the real-time state information corresponding to the foreign matter distribution state does not contain any similar feature corresponding to the state information of the carriage component, judging that the type of the ectopic object belongs to a non-train internal object, and otherwise, judging that the type of the ectopic object belongs to a train internal object. Further, when the type of the ectopic object is judged to be an object in the train, prompt information is directly sent to a supervision center of the carriage, and the prompt information is used for representing that parts in the train are shifted.
It should be understood that the real-time status information may be at least one of image information and thermal imaging information, where the image information generally includes video and/or image information, and when any similar feature corresponding to the status information of the cabin component is included, that is, the status information of the cabin component and the real-time status information reach the corresponding similar threshold condition, it indicates that the foreign object corresponding to the real-time status information is likely to be the cabin component or include the cabin component, and at this time, prompt information should be directly sent to the supervision center of the cabin, otherwise, if any similar feature is not included, the category of the ectopic object is a non-train internal object.
As shown in fig. 4, as a preferred embodiment of the present invention, the acquiring the circulation track of the ectopic object in the carriage, and tracing the state switching bit of the ectopic object according to the circulation track of the ectopic object in the carriage specifically includes:
S30: acquiring original image information containing all the ectopic objects, wherein the original image information is acquired at equal time intervals; the purpose of the equal time interval acquisition is to: whether the distance to the feature points reaches the first distance is convenient to recognize more quickly, because if the ectopic object is not subjected to external force, the ectopic object should remain in the original state, and the distance between the feature points should be uniform instead of reaching the first distance; this embodiment obviously includes a scenario in which feature recognition can be performed on at least one ectopic object;
S31: screening out image information of the same ectopic object contained in the original image information according to the characteristic information of the ectopic object, and generating first image information; the characteristics of the ectopic object generally include one or more of partial or total appearance characteristics, volume characteristics, odor characteristics, etc.;
S32: sequencing the first image information according to the sequence of the time stamps to generate second image information; since the first image information may contain different states of the ectopic object, the states of the ectopic object at different time nodes can be distinguished by the time stamp;
S33: according to the distribution of the same ectopic object in the second image information, constructing a circulation track of the same ectopic object; the circulation track is used as a substrate, and a gridding reference interval can be formed on the substrate, so that the first distance can be more conveniently and intuitively judged, and the circulation track can be convenient for subsequent investigation;
s34: marking characteristic points of the same ectopic object in the circulation track of the same ectopic object; the feature points may be virtual points corresponding to points on the physical outline features of the ectopic object, and the virtual points may be one or a plurality of virtual points; it is preferably a stable feature point, i.e. a feature point that is not easily deformed;
s35: judging whether the distance between every two feature points reaches a first distance;
s36: and if the distance between every two feature points reaches a first distance, marking the sub-areas corresponding to the two feature points as feature sub-areas, wherein the state switching bit comprises the feature sub-areas.
It should be understood that, considering that when an ectopic object exists in the hidden characteristic area, during the circulation process, there may be a situation that the circulation is interrupted, and the circulation interruption is most likely caused by external forces, where the external forces mainly include one or more of manual actions (mainly including pick-and-put actions and unintentional kick actions), acceleration and turning actions of the train, and in these situations, there may be irregular variation in circulation of the ectopic object, so that a situation that the distance between the characteristic points reaches the first distance may occur, where the situation may most likely cause a change in morphology of the ectopic object (but still be in a range that can be accurately identified), and for this situation, there may be a great deal of problems related to identification and liability disputes of the ectopic object, and thus by recording sub-areas corresponding to the characteristic points caused in these situations, it is possible to correspondingly obtain the characteristic sub-areas, and provide a decision basis for circulation supervision of the ectopic object by the subsequent management center.
As shown in fig. 5, as a preferred embodiment of the present invention, the tracing the state switching position of the ectopic object according to the circulation track of the ectopic object in the carriage specifically further includes:
s40: identifying initial sites and terminal sites corresponding to the ectopic objects in the circulation track;
S41: and respectively positioning at least one sub-region corresponding to the initial site and the terminal site according to the physical positions of the initial site and the terminal site in the carriage, and generating a positioning sub-region, wherein the state switching position comprises the positioning sub-region.
The present embodiment provides a method for tracing the status switching position of an ectopic object directly according to the initial position and the end position of the ectopic object, because at the initial position, there is a high possibility that the ectopic object falls off, and at the end position, there is a high possibility that the ectopic object is picked up or remains, that is, there is a possibility that the status switching position, and the intuitive "coming pulse-out" of the ectopic object is facilitated by the positioning sub-areas generated by the initial position and the end position.
As a preferred embodiment of the present invention, the determining the coordinate of the ectopic object according to the state switching bit specifically includes:
S50: and identifying the coordinate corresponding to the state switching bit according to the distribution corresponding relation between the pre-constructed sub-region and the functional region in the carriage.
Generally, the functional areas in the car mainly include a (passenger) seat area, an aisle, a public area, etc., which may be represented by a multi-level code, where the multi-level code includes a combination of a primary code, a secondary code, and a tertiary code, for example, the primary code represents a car number, and specifically, for example, in the distribution correspondence, the sub-areas are 3-02-22A,3 represent No. 3 car, and 02 represent a seat area, 22A, represent a 22 nd row a seat, so that the meaning is: the coordinates to which the state switching bits correspond are: carriage No. 3, seat zone at row 22a seating position, and most likely in the area covered by the seat.
As shown in fig. 6, still further, in order to enhance the practical application effect of the present application, the platform further includes a notification module 500, where the notification module 500 is specifically configured to: generating notification information according to the belonging coordinates of the different objects, and sending the notification information to at least the management and control center corresponding to each carriage.
