Kind of instrument, instrument detect watering equipment, and send special messenger to carry out on-site maintenance to the data of instrument, instrument to collect, copy and take,
And it counts, report step by step.The disadvantage is that heavy workload hand-manipulated, operating efficiency is low, and control real-time is poor, it is difficult to meet big model
Enclose the needs of data acquisition.
(6) fire demand water supervision missing
Fire demand water influences entire yard safety, and to offset anti-management of the use of water dynamics inadequate for existing plumbing management, causes
Many fire extinguisher canvas hose hydraulic pressure are too low or even water shortage.
(7) emergency reaction is difficult
It when there is contingency or emergency, needs remotely to control the start and stop of plumbing equipment, and existing gives
Drainage management is difficult to cope in time.Therefore, it is necessary to should promptly stop signal, the confession of long-range line disconnection by central server transmission
It gives, guarantees the safety of monitored target.
(8) managing power consumption lacks
Traditional plumbing operation process management mostly uses " men-to-men defense " way to manage, lacks effective management means, no legally constituted authority
Efficiency, the energy consumption for counting watering equipment, less can be carried out Energy Efficiency Analysis or management；Meanwhile existing plumbing acquisition equipment range is wide,
Quantity and classification are more, and used communication protocol is not quite identical, and administrative department is difficult to all Data Centralized Processings.Cause
This, needs to establish plumbing monitoring management system, carries out supply and drain water system and intelligent monitoring and digital management.
To sum up, current China railways plumbing equipment or structures auto-control degree are lower, and robot control system(RCS)
Software and hardware standard system is different, and building water supply and drainage robot control system(RCS) hardware and software device is directly applied at part station, ignores railcar
