Addressing Industry Issues
The water supply and drainage system is out of control, with a high risk of water interruption/flooding
Ordinary instruments have poor reliability, are prone to corrosion and blockage, resulting in a shortage of domestic water supply, insufficient fire water, underground parking garage flooding, equipment damage, and high compliance risks.
Multiple system interference, unstable BAS network
There are many building equipment, complex electromagnetic environment, signal jumping, network interruption, system paralysis, monitoring failure, and passive operation and maintenance.
Data island, unable to link various systems
Incompatible protocols and data interoperability among different brands of equipment, independent operation of HVAC/plumbing/fire protection, inability to coordinate optimization, high energy consumption, and low management efficiency.
Operation and maintenance rely on manual labor, with low efficiency and high costs
There are many building locations and wide distribution, manual inspection/recording is time-consuming and laborious, data lag, late fault detection, and high maintenance costs.
Fire compliance risks, difficult to pass acceptance
Inaccurate pressure monitoring of fire water tanks/pipelines, no alarm traceability, non-compliance with fire regulations, failure to pass acceptance, and facing fines for rectification.
Lack of energy consumption data, no basis for energy-saving optimization
No precise energy/water consumption data, inability to locate high energy consuming links, blind energy-saving measures, poor effectiveness.
