Off-line water control has a distinct advantage that it does not require wiring. Its network construction cost is low, and the system can be infinitely scalable and stable. Customers generally choose the offline water control system largely for the following reasons.
For example, in the bathhouse and boiling water room, they have water control subsystems. In addition to controlling these, they also need to control the faucets in the washing machines, drinking fountains, student apartments, and even relatively scattered areas such as electricity in apartments. When using any type of water controller, it is necessary to consider its scalability, and in this regard, the networking type will be far behind, especially the water control device implemented by the large one-card system. It is based on the library, if the system has a certain place. Problems or communication breaks. Short circuit, the entire system can not be used. This is also a major drawback of the networked type, so many customers generally prefer to purchase an off-line water control system when setting up a large-scale system.
The difference between the offline water control system and the networked water control system is that the former has no consumption details and cannot report the card function. It must use a capture card to collect the total consumption of each water control machine. The latter is obviously opposite to the former and can be used for detailed consumption, report loss, etc., and the data can be collected in real time. So why do many people choose to go offline?
