newest!Chengdu Metro Flood Control "Intelligent Supervision" optimization and upgrade

The subway drainage system, as the "main force" to ensure the smooth drainage of the stations and sections, assumes an important role in ensuring safe operations. As one of the most important drainage equipment, the water pump is one of the important drainage equipment, and the online monitoring and fault diagnosis of real -time and effective operation of it is a necessary means to improve the safety and reliability of equipment operation.

At present, it is the critical period of "seven or eight" flood control. The optimization and upgrading improved the functional and accuracy of the monitoring system.

The new method realizes the real -time "retrieved+collection+update" in real time

"The establishment and operation of the system depends on the support of strong database support. The four principles of" realizing sharing, reducing redundancy, maintaining independence, and centralized control 'are the basic prerequisites. Professionals have re -cleaned the water pump operation time analysis system data pool , Category, reorganize, and clear the historical data of all water pumps that have been stored in the past, and re -accumulate the original data of the analysis according to the line. "The company's relevant person in charge introduced to reporters.

It is understood that when the data pool is accumulated to a certain degree, professionals re -establish a new database by establishing an analytical scenario model. At the same time, in order to keep the data updated in real time, the connection channel between the database and the comprehensive monitoring system has been established, which can be retrieved in real time. Prepare for the analysis work.

The new interface implements hierarchical division key visual monitoring and management

At present, there are 13 operating lines in Chengdu Metro, with a mileage of 558 kilometers. Facing the large -scale and complicated situation of large -scale network operation management, more intelligent, refined, and scientific hierarchical control models can effectively improve risk early warning and emergency response efficiency.

"Based on the existing system functions, professionals have sorted out key content, integrate interface modules, and re -establish scene analysis models to develop a set of visual expressions and more visual and actual availability. The interface. The person in charge said.

So, what functions are the new interface "new"?

"Read red" warning in time. The new interface can not only directly display the operating status of the pump and the control position of the pump. When the device runs abnormally, the corresponding module will turn red, reminding the staff to pay attention to the status of the pump.

Focus on key management and control. After the optimization, the new interface can not only monitor and view the operation of the entire line of water pumps, shows that the total operating time of all water pumps on the entire line of the entire line can be arranged through data integration and calculation. The longest running water pumping group realizes the hierarchical monitoring, control and control and focusing recognition from the line to the specific site and the point. During the flood season, the staff will regularly retrieve the data for analysis. When a certain water pump runs abnormally, it will further analyze the precipitation and drainage system operation of the station area where the pump is located. It depends on the abnormal situation. Cause is caused by equipment failure, which is easy to take targeted measures in a timely manner.

New feature screening query function improves information extraction efficiency

On the basis of the above content, the optimized and upgraded water pump operation time analysis system also adds screening query functions, which can sort and screen for the running time of the pump in any time period. Improve information acquisition efficiency, and helps staff can understand the operation of flood control equipment within the same period of the same period of the previous year, reflecting the ability to bear the amount of precipitation and line drainage system in the flood season of the year, and provide a reference for subsequent flood prevention work.

For example, before the flood season, in order to prepare for flood prevention, staff can retrieve the operating data of the water pump in the same period of the previous two years. Combined with the current precipitation and equipment operation, it is possible to analyze which stations or points need to be focused on. Targeted flood prevention materials or equipment to improve risk prevention capabilities. "Optimized and upgraded the operation time analysis system of the pumping time, which improved the convenience of staff during actual operation. It is the actual application of 'scientific and technological innovation and smart maintenance' in production. The spirit is also the reality of the deep practice of the Chengdu Metro deeply practicing the core values ​​of the "dedication, progress, professional, and integrity 'rail core values." The person in charge said.

It is reported that the subsequent Chengdu Metro will combine the actual usage of the system, summarize and analyze, continue to optimize, use comprehensive monitoring big data platforms to improve maintenance and quality and efficiency, further accelerate the intelligent operation and maintenance and refined management of Chengdu rail transit, and ensure the safety and efficiency of citizens and passengers, and to ensure the safety and efficiency of citizens and passengers. Green and comfortable travel.
