[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combine the following Figure 1-Figure 6 The present invention describes the rain and snow pattern detection method, device, equipment, medium and computer program product.

[0026] Figure 1 is one of the flow charts of the rain and snow mode detection method provided by the present invention, such as Figure 1 As shown, the method includes the following: Step 100: Generate an idling slip alarm based on the received train idling slip state change information; the change information is generated by the train tracking service module based on the train idling slip alarm information; the train idling slip alarm information is reported by the onboard controller; The present application provides a train rain and snow mode detection method and system based on a fully automatic operation (FAO) system. The train automatic monitoring system (ATS) provided in the present application includes a train linkage control module, a train tracking service module, and a control display terminal.

[0027] The train tracking service module is used to collect and forward the train idling slip alarm information reported by the onboard controller of the (mainline operation) train. The onboard controller encapsulates the train idling slip alarm information in the alarm information frame and periodically sends it to the train tracking service module. The train tracking service module detects changes in the train idling slip alarm information, that is, compares the alarm information of the previous cycle stored in the train tracking service module with the alarm information of the current cycle. When a change in the alarm information is detected, the train tracking service module sends the train linkage control module information on the change in the train idling slip state, that is, the change information of the train idling slip state in this embodiment.

[0028] Step 200: encapsulate the train unit information and the idling slip alarm into metadata, and store the metadata; After the train linkage control module receives the change information of the train idling slip status reported by the train tracking service module, it detects that the train has an idling slip alarm, determines the station section to which the train currently belongs according to the section where the train is currently located, encapsulates the current train's vehicle group information and current time into a metadata, and stores the metadata in the train idling slip information storage data structure corresponding to the station section.

[0029] Step 300, receiving the rain and snow mode determination parameter sent by the control display terminal; The control display terminal provided in this application can be used to set the rain and snow mode judgment parameters, and three rain and snow mode judgment parameters are used as examples for explanation: 1. The threshold value of the number of trains that experience idling slip in the rain and snow mode; 2. The threshold value of the number of station sections where trains experience idling slip; 3. The time threshold for idling slip. Relevant personnel can set the above three rain and snow mode judgment parameters on the control display terminal according to regulations and needs. After the setting is completed, the control display terminal sends the rain and snow mode judgment parameters to the train linkage control module in real time. The train linkage control module stores the rain and snow mode judgment parameters to determine whether it is necessary to output a prompt to set the rain and snow mode to the control display terminal.

[0030] Step 400: Based on the metadata and the rain and snow mode judgment parameters, send the rain and snow mode detection result to the control and display terminal.

[0031] The train linkage control module periodically polls the data structure storing the train idling slip information, takes out all metadata of idling slip, and judges whether the following judgment conditions are met based on the rain and snow mode judgment parameters: 1. Whether the difference between the time when the train idling slip occurs and the current time is less than the idling slip time threshold set by the control display terminal. If it exceeds the idling slip time threshold, the metadata is deleted from the data structure storing the train idling slip information; 2. The metadata is classified with the train vehicle group information as the key value, and it is judged whether the number of all trains with idling slip alarms is greater than the idling slip train number threshold set by the control display terminal; 3. The metadata is classified with the station yard interval as the key value, considering that the same section may belong to different station yard intervals. If the vehicle group information and alarm time in the metadata of the train idling slip alarm in different intervals are the same, the metadata is only classified into the station yard interval with the largest total number of metadata. It is judged whether the number of station yard intervals with train idling slip alarms is greater than the number threshold of station yard intervals with idling slip set by the control display terminal. If the above three judgment conditions are met at the same time, the train linkage control module sends a prompt to set the rain and snow mode to the control display terminal, that is, the rain and snow mode detection result in this embodiment.

[0032] The control display terminal pops up a dialog box to report the station section information and train information where the train idling and slipping occurred, and prompts relevant personnel to set the rain and snow mode. After the prompt is completed, in order to avoid repeated prompts, the train linkage control module will clear all stored train idling alarm information.

[0033] This embodiment realizes accurate detection of rain and snow mode through a train automatic monitoring system composed of a control display terminal, a train tracking service module, and a train linkage control module. Among them, the control display terminal is used to set the rain and snow mode judgment parameters and provide them to the train linkage control module; the train tracking service module receives the train idling slip alarm information sent by the on-board controller, and generates the train idling slip state change information based on the train idling slip alarm information, and sends the change information to the train linkage control module; the train linkage control module generates an idling slip alarm based on the train idling slip state change information, encapsulates the idling slip alarm and the train vehicle group information into metadata and stores them, and finally sends the accurate rain and snow mode detection results to the control display terminal by comparing the rain and snow mode judgment parameters and the stored metadata.

[0034] In one embodiment, the rain and snow mode detection method provided in the embodiment of the present application may also include: the change information is generated by the train tracking service module when the change detection result indicates that the train idling slip alarm information has changed; the change detection result is obtained by the train tracking service module performing change detection on the train idling slip alarm information.

[0035] The rain and snow mode detection method provided in the embodiment of the present application may also include: if the train idling slip alarm information is reported by the on-board controller at different time points, then determining that the change detection result obtained by performing change detection on the train idling slip alarm information indicates that the train idling slip alarm information has changed.

[0036] According to the above content, the train tracking service module can receive the train idling slip alarm information reported by the on-board controller, and perform change detection based on the train idling slip alarm information of the previous cycle stored in the train tracking service module. If the train idling slip alarm information reported by the on-board controller changes at different time points, the train tracking service module generates the change information of the train idling slip state based on the change detection result representing the change of the train idling slip alarm information, and sends the change information of the train idling slip state to the train linkage control module, and the train linkage control module generates an idling slip alarm based on the received change information of the train idling slip state.

[0037] This embodiment analyzes the train idling state through the interaction between the train tracking service module and the train linkage control module, providing a data basis for accurately detecting the rain and snow mode.

[0038] Figure 2 FIG. 2 is a flow chart of the rain and snow mode detection method provided by the present invention. Figure 2 As shown, the method may also include: Step 410: determining idling slip data based on the metadata; the idling slip data includes train idling slip time, the number of idling slip trains, and the number of station sections where idling slip occurs; Step 420, comparing the idling slip data with the rain and snow mode judgment parameter to obtain a comparison result; Step 430: Send the rain and snow mode detection result to the control and display terminal according to the comparison result.

[0039] The rain and snow mode detection method provided in the embodiment of the present application may further include: Step 431: When the train idling slip time is greater than the time threshold, the number of idling slip trains is greater than the train number threshold, and the number of station intervals is greater than the interval number threshold, a rain and snow mode detection result is sent to the control and display terminal; the rain and snow mode detection result indicates that a rain and snow mode setting prompt message is sent to the control and display terminal.

[0040] The specific process of the algorithm for detecting rain and snow mode in the train linkage control module is as follows: 1. The train linkage control module receives the change information of the train idling slip status in real time, and encapsulates the train unit information and idling slip alarm into metadata, and stores it in units of the station section where the train is currently located.

[0041] 2. The train linkage control module receives the rain and snow mode judgment parameters set by the control display terminal in real time, such as the number threshold of trains that experience idling slip, the number threshold of station sections that experience idling slip, and the time threshold for idling slip, and stores the set rain and snow mode judgment parameters.

[0042] 3. Regularly poll the metadata of all train slip alarm information stored on the main line.

[0043] 4. Retrieve the metadata of all train slip alarm information stored on the main line.

[0044] 5. Check whether the time interval between the alarm time in the metadata and the current time is less than the set time threshold.

[0045] 6. The alarm information that does not meet the time threshold (exceeds the idling slip time threshold) is deleted from the storage data structure.

[0046] 7. Classify the train alarm information metadata that meets the time threshold using the station interval as the key value.

[0047] 8. Considering the impact that the same section may belong to different station intervals, if the train set information and alarm time in the train slip alarm metadata in different intervals are the same, the metadata will only be classified into the station interval with the largest total number of metadata.

[0048] 9. Check whether the number of station sections where air slip alarm occurs is greater than the set section number threshold.

[0049] 10. If the threshold condition of the number of station intervals is not met, exit and wait for the next polling detection.

[0050] 11. Classify the metadata of train alarm information using train set information as the key value.

[0051] 12. Check whether the number of trains with air slip alarm is greater than the set train number threshold.

[0052] 13. If the train quantity threshold condition is not met, exit and wait for the next polling test.

[0053] 14. If the above three conditions are met, the train idling and slipping status information and the train station section information will be reported to the control and display terminal, and the setting of the rain and snow mode will be prompted to the control and display terminal.

[0054] 15. After the prompt to the terminal is completed, in order to avoid repeated prompts, all stored train slip alarm information metadata will be cleared.

[0055] 16. This polling test is completed.

[0056] It can be seen that the judgment order of the rain and snow mode judgment parameters in the algorithm for detecting the rain and snow mode by the above-mentioned train linkage control module is not limited, and the embodiment provided in this application takes the three rain and snow mode judgment parameters as an example for illustration, and does not limit the conditions for other parameters to be met. The combination judgment method of other parameters is within the scope disclosed in the embodiment of this application.

[0057] This embodiment sends accurate rain and snow mode detection results to the control and display terminal by comparing the rain and snow mode judgment parameters with the stored metadata.

[0058] In one embodiment, the rain and snow mode detection method provided in the embodiment of the present application may further include: Step 10: Based on the line information between two adjacent train natural stations, the section between the two adjacent train natural stations is divided into a plurality of station yard sections; Step 20: Create a storage data structure corresponding to each station area.

[0059] like Figure 3 and Figure 4 As shown, the present application proposes a method for dividing train yard sections. In the main line yard diagram, the entire line section is divided according to the natural stations of the trains, and the section between every two adjacent natural stations of the trains is divided into two or more yard sections.

[0060] According to the direction of train operation, it can be divided into the upward station yard section and the downward station yard section. For ordinary stations, all sections between natural station 1 and natural station 2 can be divided into the following two station yard sections: the section from natural station 2 to natural station 1, including section 1 and section 2; the section from natural station 1 to natural station 2, including section 3 and section 4. For special station types composed of sections such as turnouts and storage lines, so that some sections can be used for both upward and downward trains, the section can be allowed to belong to both the upward station yard section and the downward station yard section. All sections between natural station 1 and natural station 2 are divided into the following two station yard sections: the section from natural station 2 to natural station 1, including section 1, section 2, section 3, section 7 and related turnout sections; the section from natural station 1 to natural station 2, including section 4, section 5, section 6, section 7 and related turnout sections.

[0061] After determining the station yard interval division between natural stations of the train, a storage data structure corresponding to each station yard interval is created in the train linkage control module to store the train idling slip alarm information occurring in each station yard interval.

[0062] This embodiment reasonably divides the station yard intervals between natural train stations and creates a storage data structure corresponding to each station yard interval, thereby eliminating the station yard interval factors that affect the idling and slipping of trains and improving the accuracy of rain and snow mode detection.
