Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit technology, and in particular to a method for refreshing a monitoring display interface of a rail transit station yard, a device for monitoring a rail transit station yard, and a computer storage medium. BACKGROUND

[0002] A station yard diagram is used to display a full-line track layout diagram, train position information, train number information, and the state of main trackside equipment such as turnouts, signals, and track sections in real time. Therefore, the station yard diagram plays a crucial role in monitoring automatic rail trains.

[0003] In related technologies, when performing back-end data processing, for a multi-interlocking station yard diagram, the equipment ID (Identity document, identity number) of the interlocking area is used as a unique identifier, and a hierarchical reference relationship is used to recursively address the unique equipment identifier layer by layer. When refreshing the interface state number, the back-end data creates an array object of the same type of equipment, such as signals and track sections, and then sorts and writes according to the specified order to ensure that the object writing follows a unique sorting method.

[0004] However, using a hierarchical reference will result in excessive repetitive workload in finding the corresponding device state, causing significant resource consumption. In addition, when refreshing the interface, such as refreshing a single signal, other signal states will be attached, thus increasing the power consumption of interface refreshing and requiring a higher display screen. SUMMARY

[0005] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present application is to provide a method for refreshing a monitoring display interface of a rail transit station yard, which does not require hierarchical reference relationships for device addressing, reducing resource waste caused by hierarchical references, and having low refresh power consumption when refreshing the interface.

[0006] A second object of the present application is to provide a computer storage medium.

[0007] A third object of the present application is to provide a device for monitoring a rail transit station yard.

[0008] In order to achieve the above object, the first aspect of the present application provides a method for refreshing a monitoring display interface of a rail transit station yard, wherein the monitoring equipment of the rail transit station yard comprises an OPC (OLE for Process Control) server, and the method is used for the OPC server, and the method comprises the following steps: obtaining original monitoring data of station yard equipment; obtaining identity information and state attribute information of the station yard equipment according to the original monitoring data; determining a target station yard equipment whose state changes according to the state attribute information; obtaining the identity information of the target station yard equipment, and querying a configuration data model library according to the identity information of the target station yard equipment and the state attribute information to obtain a state attribute path of a display interface corresponding to the target station yard equipment; and rewriting a state attribute value of the state attribute path to refresh the display interface corresponding to the target station yard equipment.

By parsing the original monitoring data, a data basis is provided for determining the state attribute path of the display interface corresponding to the station yard equipment.

[0012] In some embodiments, the state attribute information is named according to the name of the state of the corresponding station yard equipment. This facilitates the state attribute path query and makes it easier to rewrite the state attribute value.

[0013] In some embodiments, before rewriting the state attribute value of the state attribute path, the method further includes: obtaining a variable attribute of the state attribute information, wherein the variable attribute includes read-write identification information of the state attribute information; and determining, according to the read-write identification information, that the state attribute information does not have read-write capability and prompting. The error prompt for the non-writable variable enables the user to know that the current state attribute value cannot be rewritten and refreshed, thereby improving the accuracy of monitoring.

[0025] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary, and embodiments of the present application are described in detail below.

[0026] In an embodiment, as shown in FIG. 1, a schematic diagram of monitoring a rail transit station framework according to an embodiment of the present application is shown. Field rail data is collected by a rail external subsystem such as a vehicle-mounted device, an interlocking device, and based on an OPC server, the data is collected and parsed, and state monitoring and real-time refreshing of a station framework display interface is achieved. Figure 1

[0027] The method for monitoring a rail transit station according to an embodiment of the present application is described below with reference to FIG. 2, wherein the equipment for monitoring a rail transit station includes an OPC server, and the method is used for the OPC server. As shown in FIG. 2, the method for monitoring a rail transit station according to an embodiment of the present application includes at least steps S1-S5. Figure 2 Figure 2 The method for monitoring a rail transit station according to an embodiment of the present application includes at least steps S1-S5.

[0028] Step S1, original monitoring data of station equipment is obtained.

[0029] In an embodiment, the original monitoring data is field rail data, and the field rail data is collected by station equipment such as an interlocking device, a vehicle-mounted device, or a signal machine device, and through communication between an interface server of the OPC server and the interlocking device, the vehicle-mounted device, or the signal machine device, the interlocking data, the vehicle-mounted data, or the signal machine data is obtained, and the obtained data is used as the original monitoring data.

[0030] Step S2, identity recognition information and state attribute information of the station equipment are obtained according to the original monitoring data.

[0031] In an embodiment, after the OPC server obtains the original monitoring data, the original monitoring data is parsed, and after the parsing is completed, the identity recognition information and the state attribute information of the station equipment are obtained, for example, the identity recognition information of the signal machine device is obtained, and corresponding state attribute information such as signal machine light state, signal machine blocking or reopening, etc. is obtained.

[0032] Step S3, a target station equipment with a state change is determined according to the state attribute information.

[0033] In an embodiment, by monitoring the state attribute information of the station equipment, when the state attribute information of the station equipment changes, the target station equipment with a state change is determined, for example, when the color of the signal machine light changes from green to red, it is considered that the state attribute information of the signal machine light has changed, and thus the target station equipment is determined to be the signal machine light.

[0034] ​​Step S4, obtaining the identity information of the target station yard device, and querying the configuration data model library according to the identity information and the state attribute information to obtain the state attribute path of the display interface corresponding to the target station yard device.

[0035] In an embodiment, the identity information and the state attribute information of the target station yard device are one-to-one corresponding. After the target station yard device is determined according to the state attribute information, the identity information of the target station yard device is also determined. The obtained identity information and the state attribute information are taken as the configuration data model, and the state attribute path of the display interface corresponding to the target station yard device is determined by querying the configuration data model library.

[0036] Specifically, the configuration data model library includes a plurality of configuration data models. The identity information and the state attribute information of each station yard device correspond to a state attribute path, i.e., a configuration data model. The plurality of configuration data models form the configuration data model library, and the configuration data model library is stored to the OPC server. After obtaining the identity information of the target station yard device, the state attribute path of the display interface corresponding to the target station yard device can be directly determined by querying the configuration data model library according to the identity information and the state attribute information, without the need for cyclic iteration to find the write point, thereby avoiding the problem of large workload in finding the corresponding device state caused by hierarchical reference, so as to reduce resource consumption.

[0037] Step S5, rewriting the state attribute value of the state attribute path to refresh the display interface corresponding to the target station yard device.

[0038] In an embodiment, after the state attribute path of the display interface corresponding to the target station yard device is determined, the state attribute value of the state attribute path is directly rewritten. For example, when the color of a signal lamp changes, the state attribute path of the display interface corresponding to the target station yard device, i.e., the signal lamp, is also determined. At this time, the state attribute value of the state attribute path is directly rewritten according to the path, for example, the state attribute value is changed from 0 to 1, to realize the refresh of the display interface corresponding to the target station yard device, i.e., directly refreshing the color of the signal lamp on the display interface, without the need for any logical processing of the interface, thereby reducing the interface logical processing process, which is conducive to the interface refresh, makes the interface display more smooth, and only rewriting the state attribute value of the state attribute path, only a single signal is refreshed when the display interface corresponding to the station yard device is refreshed, thereby saving the interface refresh power consumption.

[0039] According to the method for refreshing a monitoring display interface of a rail transit station yard provided in the embodiments of the present application, the target station yard device whose state changes is determined according to the state attribute information, and the identity recognition information of the target station yard device is obtained. According to the identity recognition information and the attribute state information of the target station yard device, the state attribute path of the display interface corresponding to the target station yard device is queried in the configuration data model library, that is, the state attribute path of the corresponding display interface is directly determined based on the obtained identity recognition information and the attribute state information of the target station yard device, and the refreshing of the display interface corresponding to the target station yard device is implemented by rewriting the state attribute value of the state attribute path, without using the hierarchical reference relationship for device addressing, thereby avoiding the problem of heavy workload of corresponding device states caused by hierarchical reference, and reducing resource consumption. In addition, only the state attribute value of the state attribute path is rewritten, and when the display interface corresponding to the station yard device is refreshed, single signal refreshing is performed, thereby saving interface refreshing power consumption and making the interface display more smooth.

[0040] In some embodiments, the method for refreshing a monitoring display interface of a rail transit station yard further includes determining the state attribute path of the display interface corresponding to each station yard device according to the state attribute information and the identity recognition information of each station yard device; and all the state attribute paths form a configuration data model library. The unique state attribute path of the display interface corresponding to the station yard device is determined according to the state attribute information and the identity recognition information of the station yard device, for example, the identity recognition information of the train number and the skip-stop state attribute information of the train number form a unique state attribute path, or the identity recognition information of the signal machine and the reopening attribute information of the signal machine form a unique state attribute path, that is, a configuration data model. By setting the configuration data model library, when the state of the first station yard device changes, the state attribute path of the display interface corresponding to the first station yard device is determined according to the identity recognition information and the state attribute information of the first station yard device, and the state attribute value of the state attribute path is rewritten to implement display interface refreshing, without the need for logical processing of the display interface, thereby improving the display interface refreshing efficiency and making the rail transit monitoring more smooth.

[0041] In some embodiments, when the identity recognition information and the state attribute information of the station yard device are obtained according to the obtained original monitoring data, the original monitoring data is converted into JSON format data, and the JSON format data is output to a storage module. The JSON format data is parsed to obtain the identity recognition information and the state attribute information of the station yard device, for example, the identity recognition information and the state attribute information of the signal machine are obtained by parsing the JSON format data, wherein the state attribute information of the signal machine includes signal machine light state, signal machine reopening or blocking state attribute information, and the like. By parsing the original monitoring data, a data basis is provided for determining the state attribute path of the display interface corresponding to the station yard device.

[0042] In some embodiments, the state attribute information is named by the name corresponding to the state of the station yard equipment, for example, the state attribute information of the signal machine is directly named by the signal machine reset, when there are more original monitoring data, the name is directly named, which is convenient for state attribute path query, and the rewriting of the state attribute value is easier.

[0043] In some embodiments, before rewriting the state attribute value of the state attribute path, the variable attribute of the state attribute information is obtained, wherein the variable attribute includes read-write identification information of the state attribute information, that is, by obtaining the variable attribute, the readable and writable information and the non-readable and writable information can be determined, for the non-writable variable information, when it is determined that the state of the first station yard equipment changes, the OPC server will have a corresponding error prompt, that is, according to the variable attribute, it is determined that the state attribute information does not have the read-write property, and the prompt is given. By giving an error prompt for non-writable variable information, the user knows that the current state attribute value cannot be rewritten and refreshed, and the accuracy of track monitoring is improved.

[0044] In some embodiments, after determining the target equipment whose state changes according to the state attribute information, the identity recognition information and the state attribute information of the target station yard equipment are determined as historical record information; the historical state attribute path corresponding to the historical record information is obtained; and the state attribute value of the historical state attribute path is rewritten. It can be understood that when rewriting the state attribute value of the state attribute path of the corresponding display interface, it can be judged whether the identity recognition information and the state attribute information of the station yard equipment are historical record information. If it is historical record information, it means that the state attribute value of the state attribute path has been rewritten, and when rewriting again, the historical state attribute path is directly obtained, and the state attribute value of the historical state attribute path is directly rewritten, and the rewriting process is more convenient.

[0045] In some embodiments, the method for monitoring the rail transit station yard further comprises that the OPC server receives the control instruction, converts the control instruction into a control command in JSON data format, and sends the control command in JSON data format to the target station yard equipment. For example, the monitoring personnel can directly issue a control instruction such as a signal machine reset instruction from the station yard diagram of the display interface, and the signal machine can directly control the reset of the signal machine after receiving the instruction.

[0046] In summary, according to the method for monitoring the rail transit station yard according to the embodiment of the present application, the target station yard equipment whose state changes is determined according to the state attribute information, and the identity recognition information of the target station yard equipment is acquired, the state attribute path of the display interface corresponding to the target station yard equipment is inquired in the configuration data model library according to the identity recognition information and the attribute state information of the target station yard equipment, that is, the state attribute path of the display interface corresponding is directly determined based on the acquired identity recognition information and the attribute state information of the target station yard equipment, and the refreshing of the display interface corresponding to the target station yard equipment is realized by rewriting the state attribute value of the state attribute path, without using the hierarchical reference relationship for device addressing, avoiding the problem that the corresponding device state workload is large due to the hierarchical reference, thereby reducing the resource consumption, and only rewriting the state attribute value of the state attribute path, when the display interface corresponding to the station yard equipment is refreshed, the single signal refreshing is performed, thereby saving the interface refreshing power consumption, making the interface display more smooth.

According to the identity recognition information and the attribute state information of the target station yard device, the state attribute path of the display interface corresponding to the target station yard device is inquired in the configuration data model library, that is, the state attribute path of the display interface corresponding to the target station yard device is directly determined based on the acquired identity recognition information and the attribute state information of the target station yard device, and the refreshing of the display interface corresponding to the target station yard device is realized by rewriting the state attribute value of the state attribute path. The device addressing does not need to be performed by using the hierarchical reference relationship, and the problem that the corresponding device state workload is large due to the hierarchical reference is avoided, so that the resource consumption is reduced, and only the state attribute value of the state attribute path is rewritten, and the single signal refreshing is performed when the display interface corresponding to the station yard device is refreshed, so that the interface refreshing power consumption is saved, and the interface display is more smooth.
