Various embodiments and examples according to the present invention are described below with reference to the accompanying drawings.
< method examples >
Fig. 1 is a method flow diagram of a method of health assessment of a signal system according to some embodiments of the present disclosure.
As shown in fig. 1, the method may include the following steps S110 to S140.
Step S110: and acquiring information to be evaluated of the target signal equipment.
In embodiments of the present disclosure, a signaling system may include a plurality of signaling devices. The target signaling device is any one of a plurality of signaling devices.
The signal system may be, for example, any of the subsystems described above. For example, the signal system is an ATS system, a CI system, a ZC system, a VOBC system, a DCS, an axle counting system, a power supply system, or a microcomputer monitoring system. The target signal device may be an ATS device, a CI device, a ZC device, a VOBC device, an axle counter device, a power supply device, a microcomputer monitor device, or a DCS device.
Specifically, in the case where the signal system is an ATS system, the signal device (target signal device) is an ATS device; in the case where the signal system is a CI system, the signal device (target signal device) is a CI device; in the case where the signal system is a ZC system, the signal device (target signal device) is a ZC device; in the case where the signal system is a VOBC system, the signal device (target signal device) is a VOBC device; in the case where the signal system is DCS, the signal device (target signal device) is DCS device; in the case where the signal system is an axle counting system, the signal device (target signal device) is an axle counting device; in the case where the signal system is a power supply system, the signal device (target signal device) is a power supply device, and in the case where the signal system is a microcomputer monitoring system, the signal device (target signal device) is a microcomputer monitoring device.
The information to be evaluated may include any of: device status information, device alarm information, and device maintenance information.
The device status information may include information related to the status of the device, such as the number of operations, the operating status, the real-time current value, or the real-time voltage value. Device alarm information such as device related alarm information. The equipment maintenance information may include information related to maintaining equipment, such as equipment on-time (i.e., the total time the equipment is on), equipment length of service, equipment repair times, or equipment overhaul data.
The number of information to be evaluated may be plural. In this case, all the information to be evaluated obtained in step S110 includes at least one device status information, at least one device alarm information, and at least one device maintenance information.
In some embodiments, device status information and device alarm information may be obtained from the MSS, and device maintenance information may be obtained from the asset management system.
For example, the device state information is updated in the MSS, in which case the updated device state information in the MSS may be synchronized to the local database. As another example, the device alarm information is updated in the MSS, in which case the updated device alarm information in the MSS may be synchronized to the local database. As another example, the asset management system has updated device maintenance information, in which case the updated device maintenance information in the asset management system may be synchronized to the local database.
It should be noted that, in some cases, the equipment maintenance information is stored in the work order management system, and in this case, in the case that the work order management system updates the equipment maintenance information, the updated equipment maintenance information in the work order management system may be synchronized to the local database.
Step S120: and performing risk assessment on the information to be assessed, and determining an assessment result.
The evaluation results include: the information to be evaluated has a risk, or the information to be evaluated does not have a risk.
When the information to be evaluated is subjected to risk evaluation, according to the preset risk condition corresponding to the information to be evaluated, the information to be evaluated is determined to have risk under the condition that the information to be evaluated meets the corresponding preset risk condition, and the information to be evaluated is determined to have no risk under the condition that the information to be evaluated does not meet the corresponding preset risk condition.
The preset risk condition may be a threshold determination condition obtained by setting a threshold in various ways, such as equal to, less than or equal to, greater than or equal to, or a value range.
The preset risk condition may be determined according to the device type of the target signal device.
For example, a plurality of risk assessment models corresponding to a plurality of device types one to one may be preset. For any of the plurality of risk assessment models, it may include one or more preset risk conditions. In this case, when performing risk assessment on the information to be assessed, a risk assessment model corresponding to the device type may be determined according to the device type of the target signal device, then a preset risk condition corresponding to the information to be assessed is determined in the risk assessment model, and whether the information to be assessed meets the corresponding preset risk condition is determined. Determining that the information to be evaluated has risks under the condition that the information to be evaluated meets corresponding preset risk conditions; and under the condition that the information to be evaluated does not meet the corresponding preset risk condition, determining that the evaluation result is that the information to be evaluated does not have risk.
The risk assessment model can be set by a person skilled in the art according to actual conditions, and the embodiment of the disclosure is not limited by contrast.
Before determining the risk assessment model corresponding to the device type, a first corresponding relationship between the multiple device types and the multiple risk assessment models may be preset, and in this case, the risk assessment model corresponding to the device type of the target signal device may be determined according to the first corresponding relationship.
When the preset risk condition corresponding to the information to be evaluated is determined, a second corresponding relationship between the plurality of information to be evaluated and the plurality of preset risk conditions may be preset, and in this case, the preset risk condition corresponding to the information to be evaluated may be determined according to the second corresponding relationship.
For example, the device type of the target signal device is a server, and the obtained information to be evaluated is a memory occupancy rate a of a Central Processing Unit (CPU). In this case, in a plurality of preset risk assessment models, a risk assessment model corresponding to the server may be determined according to the first mapping table, and then, according to a second mapping table in the risk assessment model, a preset risk condition corresponding to the information to be assessed is determined as follows: the memory occupancy rate is greater than the CPU memory occupancy rate upper limit B, under the condition, the obtained memory occupancy rate A is greater than the CPU memory occupancy rate upper limit B, and the evaluation result is determined to be that the information to be evaluated has risk; and under the condition that the acquired memory occupancy rate A is less than or equal to the CPU memory occupancy rate upper limit B, determining that the evaluation result is that the information to be evaluated has no risk.
Under the condition that the evaluation result is that the information to be evaluated has risk, the information to be evaluated can be used as first information to be evaluated; and in the case that the evaluation result is that the information to be evaluated has no risk, the information to be evaluated can be used as second information to be evaluated.
Step S130: and obtaining the equipment health degree score of the target signal equipment according to the evaluation result.
In some embodiments, the evaluation result may include: the information to be evaluated has a risk. In this case, the information to be evaluated may be taken as first information to be evaluated, and then the device health score of the target signal device may be obtained based on the preset total health score of the target signal device and the preset score corresponding to the first information to be evaluated (for example, the following cases (1) and (3)).
In some examples, the number of the information to be evaluated is multiple, and the preset total health score of the target signal device is the sum of preset scores corresponding to all the information to be evaluated. For example, the number of the information to be evaluated is N (N is a natural number and N > 2), all the information to be evaluated includes information 1 to N (N = N) to be evaluated, the preset total score of the health degree of the target signal device is 100, the preset score corresponding to the information 1 to be evaluated + the preset score corresponding to the information 2 to be evaluated + \ 8230 \ 8230 + corresponding to the information N to be evaluated. The preset value corresponding to the information to be evaluated 1 to the preset value corresponding to the information to be evaluated n may be set by a person skilled in the art according to an actual situation, which is not limited in the embodiment of the present disclosure.
In this case, the information to be evaluated acquired in step S110 is one of all the information to be evaluated, and in step S120, risk evaluation is performed on the information to be evaluated acquired in step S110, so the evaluation result determined in step S120 is an evaluation result for one of all the information to be evaluated. In the case that the number of the information to be evaluated is multiple, steps S110 to S120 may be performed for each of all the information to be evaluated, and any one of the following results may be obtained: all information to be evaluated is first information to be evaluated; (2) all the information to be evaluated is second information to be evaluated; (3) All information to be evaluated has m (m is a natural number and (n-1) > m > 0) pieces of first information to be evaluated and (n-m) pieces of second information to be evaluated, and the m pieces of first information to be evaluated include: the first information to be evaluated 1 'to the first information to be evaluated M' (M = M).
When the device health score of the target signal device is obtained according to the preset health total score of the target signal device and the preset score corresponding to the first information to be evaluated, the preset score corresponding to all the first information to be evaluated can be deducted from the preset health total score to obtain the device health score of the target signal device.
In the case of the above-mentioned condition (1), since all the information to be evaluated is the first information to be evaluated, the preset score corresponding to all the first information to be evaluated is subtracted from the preset total score of health degrees, and the score of the equipment health degree of the target signal equipment is obtained to be 0.
In the case of the foregoing (2), since all the information to be evaluated is the second information to be evaluated, and there is no first information to be evaluated, the preset score corresponding to all the first information to be evaluated is deducted from the preset total health score, that is, 0 is deducted from the preset total health score, so as to obtain the device health score of the target signal device, that is, the preset total health score.
In the case of the above-mentioned (3), since all the information to be evaluated has M (M is a natural number and (n-1) > M > 0) pieces of first information to be evaluated and (n-M) pieces of second information to be evaluated, the preset score corresponding to all the first information to be evaluated is deducted from the preset total score of health degrees, so as to obtain the device health degree score of the target signal device = the preset total score of health degrees-the preset score corresponding to the first information to be evaluated 1' -the preset score corresponding to the first information to be evaluated 2' -the preset score- \8230; -the preset score corresponding to the first information to be evaluated M '.
Step S140: and outputting a health degree evaluation report of the signal system according to the equipment health degree scores of all the target signal equipment.
In the embodiment of the present disclosure, the system health degree score of the signal system may be obtained according to the equipment health degree score and the preset weight of each target signal equipment. For example, for any one of all target signal devices, a product of the device health score of the target signal device and the target signal device is obtained, the product is used as a first calculated value of the target signal device, the first calculated values of all target signal devices are summed to obtain a second calculated value, and the second calculated value is used as a system health score. In this case, the system health score is used as the first information in the health evaluation report, and the health evaluation report is output. The preset weight of each target signal device may be set by a person skilled in the art according to an actual situation, which is not limited in the embodiment of the present disclosure.
In the embodiment of the present disclosure, the device health score of each target signal device may also be used as the second information in the health assessment report according to the result obtained in step S130, and the health assessment report is output.
In the embodiment of the disclosure, a maintenance suggestion corresponding to the information to be evaluated with risk is determined according to a preset mapping table; the preset mapping table includes mapping relationships between a plurality of preset evaluation information and a plurality of preset maintenance suggestions, and the plurality of preset evaluation information includes the information to be evaluated with risks (i.e., the first information to be evaluated). And then taking the maintenance suggestion corresponding to the risky information to be evaluated as third information in the health degree evaluation report, and outputting the health degree evaluation report. The repair suggestion can be used as reference information to assist a user in repairing or maintaining the related equipment. The relevant device is a device that produces information to be evaluated that is at risk.
The plurality of preset maintenance suggestions and the mapping relationship between the plurality of preset evaluation information and the plurality of preset maintenance suggestions may be set by a person skilled in the art according to actual situations, and the embodiment of the present disclosure does not limit this.
In some examples, in the embodiments of the present disclosure, a plurality of device health levels corresponding to the respective signal devices or device types are also preset for different signal devices or device types. The plurality of equipment health levels correspond to the plurality of first score intervals one by one. In this case, the target first score interval in which the health degree score is located may be determined according to the device health degree score of the target signal device, the health level corresponding to the target score interval may be used as the device health level of the target signal device, and the device health level of the target signal device may be added to the health degree evaluation report.
Similarly, in the embodiment of the present disclosure, a plurality of system health levels may also be preset, and the plurality of device health levels correspond to the plurality of second score intervals one to one. In this case, according to the system health degree score, a target second score interval where the system health degree score is located may be determined, and the health grade corresponding to the target second score interval is used as the system health grade of the signal system, and the system health grade of the signal system is added to the health degree evaluation report.
In some embodiments, after step S140 is executed, the information in the health assessment report may be managed, which may include, for example, retrieval management and ranking management to facilitate retrieval, query and analysis of health information of the signal system and the plurality of signal devices in the signal system by relevant personnel.
For example, all risk factors (i.e., information to be evaluated that is at risk) of the signal system may be uniformly managed, such as being retrievable and viewable by subsystem, status, device type, generation time, and the like. And for example, the system can be searched and sorted according to conditions such as subsystems, equipment types, evaluation time, health grades and the like, and the health degree details of the equipment can be viewed, wherein the health degree details comprise information such as health degree scores, risk factors, maintenance suggestions and the like.
In some examples, when the evaluation result of the information to be evaluated is that the information to be evaluated has a risk, a risk record corresponding to the information to be evaluated is generated, and state identification information corresponding to the information to be evaluated is output according to the risk record, for example, a risk state of the information to be evaluated is marked as present; after that, under the condition that the risk of the information to be evaluated is determined to be eliminated, the risk record corresponding to the information to be evaluated is deleted, and the risk state of the information to be evaluated is marked as solved.
The manner of determining that the risk of the information to be evaluated is eliminated may be set by a person skilled in the art according to practical situations, and is not limited by the embodiment of the present disclosure.
The following takes a signal system as an axle counting system as an example, and the method in the embodiment of the present disclosure is described in detail through a specific example.

Step S220: and acquiring a risk evaluation model of the axle counting equipment, processing the real-time synchronous information to be evaluated in the local database by adopting the risk evaluation model, and determining whether an unresolved risk item (namely the first information to be evaluated) exists.
And for the unresolved risk item, marking the risk state of the risk item as existing, if the production rule of the risk item is judged to be no longer satisfied, indicating that the risk item is solved, and marking the risk state of the risk item as solved.
Step S230: all unresolved risk items of each axle counting device are obtained, the health degree full score of the axle counting device is set to be 100, and the health degree scores corresponding to the risk items are deducted from the health degree full score of the axle counting device in sequence to obtain the device health degree score of the axle counting device.
