Description
Technical Field
The invention relates to the technical field of secondary water supply, in particular to a cloud side end cooperative intelligent water supply control scheduling method.
Background
The secondary water supply system is a system which boosts the water pressure of a municipal tap water pipe network in modes of a booster pump and the like, outputs the water pressure to households in a high-rise residential district, and the like, and ensures that the high-rise households and the like can normally use water. The booster pump of the existing secondary water supply system is generally controlled by adopting a PLC (programmable logic controller), the PLC belongs to a factory production system control method, and the PLC has the advantages of simple application and programming, low cost and high reliability. Although the PLC control water supply mode has certain advantages, the PLC control water supply mode also has the following defects that the storage capacity is limited, the performance is low, an operating system is not provided, the programming mode can only be an algorithm library provided by a manufacturer, meanwhile, the PLC control water supply mode is limited in capacity, not suitable for collecting large data volume, and not capable of completing the algorithm with the aspect of artificial intelligent scheduling. After the PLC control system is put into use, due to the fact that the pre-programmed program and the operation parameters in the PLC control system are fixed and invariable. For example, a large residential district has a long time from the initial residence time to the residence time of a large number of residents, which generally lasts for more than several years, so that the water consumption of the residents in the district also changes from small to large in practical situations; the difference of the water consumption of every day different time frame is also great, has the water height peak condition, and different periods, different periods need adopt different operating parameter, because PLC control system's control parameter etc. can't adjust in real time according to the water consumption, can lead to the water supply pressure, the water supply volume of later stage unstable, and the user water consumption receives the influence, experiences not well, and exists that the energy consumption is high, the operation cost increases, and influences the whole life's of equipment shortcoming. If PLC reprogramming is carried out according to later-stage water consumption data, a professional technician is required to reprogram the PLC, and a plurality of data such as water quantity, water pressure and the like in different time periods are acquired from a field water consumption area by the technician as a programming basis, so that the defects of high investment and inconvenience brought to related technicians exist, and the subsequent water supply effectiveness cannot be ensured based on the manually acquired data (for example, the water consumption of residents is not only influenced by different time periods every day, but also influenced by factors such as seasonality, and the accuracy of water consumption rule data cannot be completely ensured by the water consumption data acquired by the technician). In conclusion, the working mode of the PLC for controlling the secondary water supply system has great limitation.
The edge gateway controls the working mode of the water supply equipment, encrypts data and access authority based on encryption hardware or a block chain technology, has the advantages of large storage capacity, strong performance, high safety and flexible development, combines the advantages of an algorithm and computing capacity, and can improve the reliability and the operation capacity of the control of the water supply equipment. However, the conventional gateway only has a data acquisition function and an analysis function, directly plays a role of a bridge in the PLC and the cloud platform, and does not have a water supply control logic, a data analysis function and an algorithm function. The working mode of controlling the water supply equipment by using the edge gateway alone needs to normally control the electric equipment under the condition that the network is kept smooth, so the method has certain limitation, and has not been applied to the control of a secondary water supply system. Cloud platforms have strong storage and computing capabilities, but are directly applied in water supply management, since water supply requires real-time control, it is costly in terms of large concurrent real-time control, and in case of network instability, it is easy to cause risks of water supply instability or unpredictability. In addition, although the cloud service based on the cloud platform has strong storage and computing capabilities and artificial intelligence deployment advantages, the cloud service cannot be directly connected with the PLC, and a plurality of PLCs cannot be connected with the cloud platform in real time, so that the gateway becomes a bridge between the cloud platform and the PLCs. In summary, it is very necessary to provide a method for controlling the operation of the secondary water supply system based on the advantages of the PLC, the edge gateway and the cloud platform.
Disclosure of Invention
