Description

Butt joint method of equipment state monitoring system and asset management system of rail transit

Technical Field

The invention relates to the technical field of track traffic real-time signal monitoring, in particular to a butt joint method of a track traffic equipment state monitoring system and an asset management system.

Background

The technology for interfacing the real-time state monitoring system and the enterprise asset management system based on the track traffic signal equipment is a full-period closed-loop management software technology developed for effectively linking the real-time state of the track traffic signal equipment and the asset management system. The existing monitoring systems and asset management systems basically operate independently, the data among the systems are difficult to realize intercommunication and sharing, the operation and maintenance are carried out manually, the maintenance cost is high, and the requirement on automatic intelligent maintenance of the asset equipment cannot be met.

In the prior art, for asset monitoring systems, asset management systems, independent operation and maintenance, and information between systems cannot be shared in the industry. The creation of work order only needs to rely on the field inspection to examine and repair the back and input and just generates, can not pinpoint the trouble problem in real time, and inefficiency is with high costs:

1. The system monitors massive alarm data in the system, fails to discover key equipment fault data of potential safety hazards in time without analysis and processing, and fails to generate a work order in time for maintenance by the asset management system, so that great operation risks exist.

2. A single asset management system has little information available. The information link platform cannot be established, and the equipment state and maintenance effect are not dynamically tracked, fault intelligent analysis and fault real-time maintenance are not performed.

3. The real-time data of the equipment is basically obtained by adopting manual offline, and meanwhile, the data actually required by the asset management system is not personalized.

4. The traditional docking mode is only responsible for providing device status data, and is less concerned about whether the asset management system is data. Meanwhile, the work order data processing result of the asset management system is not processed and displayed synchronously. The mode has linkage singleness, and the full-link closed loop of the two-party system is not really realized.

Because the existing equipment state monitoring system and asset management system of the rail transit cannot be interconnected and communicated, automatic butt joint cannot be achieved, and the two systems cannot be matched efficiently, so that faults cannot be found and processed in time, and fault processing time delay is caused. Meanwhile, the equipment state monitoring system lacks the capability of collecting data analysis based on the special personalized requirements of the asset management system, so that the fault equipment which needs to be notified to the asset management system cannot be pushed accurately.

Therefore, how to avoid the fault handling delay and accurately push the notification to the fault equipment of the asset management system is still a problem to be solved by the person skilled in the art.

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The problem that the fault processing time is prolonged and the fault equipment of the asset management system cannot be accurately pushed and notified due to the fact that the two systems cannot be communicated with each other is common in the existing equipment state monitoring system and the asset management system of rail transit. A method for interfacing a device status monitoring system and an asset management system of rail transit according to the present invention is described below with reference to fig. 1-2. Fig. 1 is a flow chart of a method for interfacing a device status monitoring system and an asset management system of rail transit provided by the present invention, as shown in fig. 1, an execution subject of the method is a device status monitoring system, and the method includes:

Step 110: continuously counting the collected fault information and state values of each device in real time.

Optionally, the method for interfacing the device state monitoring system and the asset management system of the rail transit provided by the invention is realized on a system comprising the device state monitoring system, the asset management system, the trackside asset device and the acquisition device. The trackside asset equipment is arranged in a circuit monitored and managed by the equipment state monitoring system and the asset management system; the acquisition equipment acquires state data and fault information of the trackside asset equipment. One track line corresponds to a set of equipment state monitoring systems and asset management systems and is used for carrying out fault monitoring on all equipment in all stations in the track line. The collecting device uploads the collected device information, the device operation parameters and the device fault information to the device state monitoring system so that the device state monitoring system can carry out statistical analysis on the fault information and the state value which are continuously received in real time, and whether the fault device needing emergency treatment exists or not is judged. The fault information comprises operation parameters of equipment to be monitored, which are acquired by the acquisition equipment, a determined fault level and a state value, wherein the state value is a binary value of 0-1, 0 represents that the disconnection is closed and does not work, and 1 represents that the connection is powered on. And for the equipment state reporting request with the fault level received by the equipment state monitoring system, a snowflake algorithm is adopted to generate a global alarm sequence ID to identify fault information of the equipment, so that the uniqueness of the alarm ID generated by the concurrent request is ensured, and meanwhile, real-time alarm data are stored in an asset state information table for convenient reading during subsequent statistical analysis.

And 120, processing the fault information based on preset rules to obtain the health degree of each device.

Optionally, the device state monitoring system performs statistical analysis on the collected fault information and state information of each device to obtain the health degree of each device based on a preset rule, where the preset rule includes a statistical calculation method of health degree, which physical parameters are required to be adopted in calculation of health degree, and a suspected device which needs to be promptly processed to release faults and needs to be subjected to calculation of health degree is screened out according to a fault level before calculating health degree, so that the preset rule has multiple possibilities, possibly only giving the calculation method of health degree and the physical parameters required to calculate, and possibly giving the calculation method of health degree and the physical parameters required to calculate, and also provides a preset fault level for screening the suspected device which needs to be promptly processed to release faults, where the preset fault level provides a rule that the calculation of health degree and the screening condition are used together as a screening condition, and is not limited in particular herein. The preset rules are provided by a configuration file formulated according to the special requirements of the asset management system, and the preset rules can be modified by modifying the configuration file, for example: for line scenarios with low fault tolerance, the fault level set for filtering is set to be low, i.e. a slight fault of the equipment needs to be screened out for analysis of health degree to determine whether to be pushed to the asset management system as an alarm message for fault handling.

Step 130, screening out equipment needing emergency treatment based on the health degree of each equipment and a preset health degree threshold value, and determining respective maintenance suggestions based on the state value of the equipment needing emergency treatment;

Optionally, after calculating the health degree of each device, comparing the sizes according to the pre-stored health degree threshold value of each device, wherein the device with the health degree lower than the corresponding threshold value is the device needing emergency treatment, and then checking the state value of the device needing emergency treatment, combining the maintenance proposal extracted from the pre-stored maintenance operation manual to obtain the final maintenance proposal which can be used as a guide maintenance personnel and sent to the asset management system.

Step 140, packaging the fault information and maintenance advice of the equipment to be processed in emergency into an alarm message, and sending the alarm message to an asset management system;

The asset management system generates a work order based on the fault information of the equipment needing emergency treatment and the maintenance advice, informs maintenance personnel of processing, and returns the work order.

Optionally, the device state monitoring system determines the device needing emergency treatment after statistical analysis, packages the fault information and maintenance advice of the device into an alarm message, and sends the alarm message to the asset management system. After the asset management system receives the alarm information sent by the equipment state monitoring system, the fault information of equipment needing emergency treatment and the maintenance suggestion generation processing worksheet in the alarm information are extracted and pushed to the mobile equipment of the corresponding maintenance personnel to inform the maintenance personnel to carry out fault elimination processing. The process of generating the work order can be added into a manual checking and judging process, namely, maintenance personnel in the machine room can manually confirm the alarm message sent by the equipment state monitoring system, and after the manual confirmation is passed, the asset management system can generate the work order based on the fault information and the maintenance suggestion in the alarm message. The asset management system then feeds back to the device status monitoring system that the work order has been generated so that real-time synchronization between the two systems is achieved with respect to the status of the work order. Specifically, when the asset management system returns the work order information, the work order information is transmitted through an HTTP protocol, and the work order information is transmitted to the equipment state monitoring system in an API mode.

And step 150, receiving the fault recovery message of the emergency processing equipment, and sending the fault recovery message to the asset management system so that the asset management system can update the work order state and return the updated work order state.

Optionally, the equipment state monitoring system continuously receives the fault information of the equipment to be monitored collected by the collecting equipment in real time, when the fault information of the equipment to be monitored, which is in the process of working order, is found to be recovered to normal, the fault recovery information is sent to the asset management system, so that the asset management system supplements the working order processing process and the fault recovery result on the working order, the updated working order is returned to the equipment state monitoring system after supplementation, so that real-time synchronization of working order state update is realized between the two systems, and the asset management system continuously pushes the updated working order to a mobile terminal of a corresponding maintainer to inform the maintainer that the fault equipment is recovered to normal.

On the basis of the foregoing embodiment, in the method, the processing the fault information based on a preset rule to obtain the health degree of each device includes:

Optionally, a configuration file in the device state monitoring system is stored separately by using a configuration interface module independent of the device state monitoring system, the configuration file stores a fault filtering level, a preset rule for calculating health degree and a preset health degree threshold, and the content in the configuration file is formulated based on the special requirement of an asset management system interacting with an execution main body of the current method, or the configuration file constructed by the asset management system interacting with the execution main body of the current method according to the requirement of the asset management system is sent to the configuration interface module. While it is further defined herein that processing the fault information to derive the health of the devices using preset rules combines fault level filtering screening with health calculations, making the process of finding the devices that need emergency treatment more efficient and less time consuming. The configuration file is stored by adopting an independent configuration interface module to facilitate the subsequent modification and adjustment of the configuration file, and meanwhile, the configuration interface module can be used as a center for acquiring configuration information for different equipment state monitoring systems, and can serve the combination of a plurality of groups of equipment state monitoring systems and asset management systems. Optionally, the fault filtering level, the preset rule for calculating the health degree and the preset health degree threshold in the configuration file may be refined as follows: data screening class, filtering out faults which do not need work order processing on site; configuring a grade type, alarm content, a fault influence range and a fault handling method which correspond to the type of equipment, wherein the grade type is in butt joint with an asset management system; the configuration file also comprises asset information types, asset information of the associated acquisition equipment is acquired, and an asset number and an asset name are acquired through the equipment number, wherein the asset refers to a real object of equipment to be monitored, which is acquired by the acquired equipment and acquires fault information; the preset rule is based on the equipment failure rate, the failure times and the risk level weight as an evaluation standard, the equipment failure data algorithm model design technology is utilized to carry out weighted superposition evaluation to obtain the health degree, and when the health degree is lower than the health degree threshold value in the configuration file, the health degree is recorded in a warehouse and is used as a decision basis of a push asset management system.

On the basis of the foregoing embodiment, in the method, the determining the health degree of the emergency suspected device based on the fault information of the emergency suspected device and the preset rule includes:

h_i＝(S_i-B_i)/S_i,E_i＝LB_i/LT_i

Optionally, when the health degree calculation is performed, the above formula provides a specific calculation method through accurate mathematical description, and it should be noted that α, β and γ as weighting coefficients in the health degree calculation formula can be adjusted according to the actual condition of the line where the system is located under the condition that the sum of the three is ensured to be 1. The process of forming the physical parameters involved in the calculation specifically comprises the following steps: based on the equipment number, acquiring equipment Map from the cache, wherein Map data comprise asset equipment numbers and asset IDs, and acquiring data such as asset numbers, asset names and the like from an asset information table of a related database; and (3) carrying out encapsulation processing on the asset data according to a data format of the docking asset management system, and adopting a MapReduce data model technology, wherein the asset data mainly comprises a Mapper real-time state fault model and a Reducer real-time fault statistical model. The Mapper class is mainly responsible for analyzing and processing the equipment state data and finally converting the equipment state data into an equipment number-equipment state value data pair; the Reduce class mainly acquires the data pair of the equipment number and the equipment state value, and then processes statistics to obtain a result.

The method provided by the invention provides a specific calculation method for the health degree through accurate mathematical description, and further defines the physical parameters contained in the fault information and the calculation rules in the preset rules.

On the basis of the above embodiment, the method, wherein determining the respective maintenance advice based on the status value of the emergency processing equipment is provided, includes:

Optionally, the transverse historical state value and the longitudinal historical state value are respectively interpreted, the transverse historical state value refers to the ratio of the number of faults of the equipment to the number of faults in the line where the equipment is located in a preset historical time period, and the longitudinal historical state data refers to the ratio of the number of faults of the equipment to the number of faults of the equipment in other lines in the preset historical time period, so that a fault maintenance suggestion of the equipment needing urgent treatment is determined, besides a conventional maintenance operation of acquiring a corresponding equipment number by inquiring a pre-stored operation manual, the historical data of the fault maintenance suggestion is further determined by taking the historical data of the fault maintenance suggestion as a reference basis, and the fault can be determined as a common fault from the historical data without manual processing, and therefore, the manual maintenance operation suggestion is not needed. In this case, there is also a method for generating the maintenance advice, that is, the equipment status monitoring system side does not directly generate the maintenance advice and pushes the maintenance advice to the asset management system, but only pushes the fault information and the status value of the equipment needing emergency treatment, the asset management system receives the fault information, extracts the corresponding equipment number, and then sends the corresponding equipment number to the maintenance operation manual stored in the asset management system to query the maintenance method, and determines the final maintenance advice by combining the received lateral historical status value and the received longitudinal historical status value of the equipment needing emergency treatment. Therefore, the maintenance advice displayed on the work order and seen by the maintenance personnel can be judged by the equipment state monitoring system and then sent to the asset management system, the asset management system can judge and generate the maintenance advice based on the original data sent by the equipment state monitoring system, the two sides can judge the maintenance advice, and the asset management system can verify the uniformity of the maintenance advice so as to ensure the accuracy of the generated maintenance advice, and the maintenance advice is not particularly limited.

Optionally, the fault information and the maintenance advice of the emergency processing equipment are packaged and encapsulated into an alarm message, which specifically comprises: creating a docking data model map, setting device state generation time, subsystem identification (which is also referred to as line identification because a line corresponds to a combination of a set of device state monitoring systems and asset management systems), and pushing data thresholds. Firstly drawing a graphic model for push data, then according to a real-time equipment state value, combining a historical state value of slave equipment, comparing a plurality of transverse and longitudinal dimensional analyses of multi-route equipment data to obtain equipment state characteristics including failure occurrence reasons, failure occurrence probability, failure influence range and failure treatment suggestion, and packaging alarm state data to obtain alarm information. And pushing the packaged alarm message to a pushing module independent of the equipment state monitoring system, and forwarding the alarm message to a corresponding asset management system after the pushing module receives the alarm message. The processing process of the pushing module is as follows: an asynchronous control method is created after the alarm message sent by the equipment state monitoring system is received, and the throughput and the stability of the server can be improved by adopting asynchronous processing service. And sending the request to a message queue, creating DiferedResult, placing the request in a map by taking the equipment number as a key and the result alarm information as a value, and sending the data to an asset management system. Fig. 2 is an exemplary diagram of a data structure of an alarm message constructed by a push module according to the present invention, where, as shown in fig. 2, a following field alarmDetailSeq、deviceName、deviceTypeNo、alarmLevel、sysNo、sysName、stationNo、stationName、status、deviceNo、bom、bomName、alarmTime in the data structure sequentially represents a global unique ID, a device name, a device type number, a fault level, a system number of a device, a system name of a device, a site number of a device, a site name of a device, a device state, a device number, a device corresponding asset, the asset name, and a fault occurrence time of a fault in fault information. The push module is also designed with a retry mechanism, if the equipment state monitoring system does not succeed in sending the equipment state data to the asset management system, namely the signal equipment real-time state monitoring system does not receive the ACK of the Broker, so that the final asset management system cannot eliminate the fault, and at the moment, the push component in the push module can automatically retry. MQProducer can set the maximum retry number of message transmission failures, and set the device state monitoring system to retry three times if the transmission is not successful within five seconds. When the asset management system receives and processes the real-time state data of the signal equipment, idempotent design is carried out, and the same state data is ensured to be processed only once.

The method provided by the invention adopts the push module independent of the equipment state monitoring system to send the alarm message, can better realize asynchronous control, ensure that the main process of the equipment state monitoring system for statistically analyzing fault information is not interfered, and can realize a timeout retransmission mechanism to avoid the missed reception of the alarm message.

On the basis of the above embodiment, the present invention provides another method for interfacing a device status monitoring system and an asset management system of a rail transit, where an execution subject is the asset management system, and fig. 3 is a schematic flow chart of the method for interfacing a device status monitoring system and an asset management system of a rail transit, as shown in fig. 3, where the method includes:
