Priority date (The precedence date is an assumption and is not a legal conclusion. The invention discloses an intelligent hydraulic balance management system system primarily based on a datum level tracking method. The control gadget contains: the system contains a principal station controller, a variable-frequency water pump set controller, a cold and heat source controller and water terminal controllers. Each controller is related with every corresponding machine. Each controller is a area management unit, and is connected with the grasp station controller to kind a DCS pc network management system. The controller of the variable-frequency water pump set tracks the most unfavorable end, namely the total load change of the system in real time on the minimum cost; while other controllers management the respective devices to track the respective end load adjustments in real time at minimal price; under the coordinated control of the grasp station controller, all of the devices of the water circulation system operate in accordance with the rule of 'actual-time load tracking and minimum cost', particularly the intelligent function of self-adaption and minimum power consumption.

Thus, the system is in an integrally optimized dynamic hydraulic steadiness state intelligently on a regular basis, and the perfect goal of supplying water on demand at the minimal price is achieved by each water use finish. The invention pertains to the sector of hydraulic steadiness management of a water circulation system. The water circulation system is extensively utilized within the production and life of staff and folks, however the problem of hydraulic imbalance affecting the safety, the operation efficiency and the quality of the water circulation system is at all times plagued in the industry; the hydraulic imbalance is the phenomenon that every finish of the system doesn't have the function of supplying water in line with the need, in order that the chilly and hot of every finish of the system are uneven, the security is reduced, the power consumption is increased, and the operation high quality is lowered; as a result of the standard reduction theory, linear considering, stacking and stacking built-in scientific paradigm and the nonlinear advanced water circulation system are not matched in nature, the formed water circulation system will not be brought on by an inherent wholesome structure.

The normal technique for iTagPro Review solving the hydraulic imbalance is to install a stability valve on a main pipe and a department pipe of a water circulation system. There are two sorts of balancing valves: constant movement kind balance valve and fixed strain sort balance valve. While the inner structure and the intrinsic operation rule of the water circulation system and the roles and features of the balance valves within the system and the adjustments of the general efficiency of the system are not quite clear for developers of the steadiness valves, the developed steadiness valves can solve the problem of hydraulic balance, but convey different issues, as proven in fig. 1 and 2, the stability valves are put in on each branch pipe, every primary pipe and every most important pipe, the balance valves are enormously difficult, each stability valve is manually adjusted to the designed circulate by utilizing costly special instruments, the process is difficult, the adjusted movement is just the designed value but not the precise value, and the distinction of two values at completely different ends can be different, mobile tracking gadget in order that the accuracy of the movement adjustment can also be totally different; in the meantime, the constant present and fixed stress efficiency of the stability valve is modified by consuming 20% -30% of the conveying power of the water pump, and the issues are opposite to the original purposes of hydraulic steadiness energy saving and operation high quality enchancment design, in order that popularization and utility of the steadiness valve are restricted.

Therefore, the standard stability valve has advanced structure, very complex structure for forming a hydraulic steadiness adjusting system, excessive manufacturing value, difficult manual debugging, low vitality saving effectivity and the like. The invention goals to supply an intelligent hydraulic steadiness control system system by a datum level monitoring methodology, which aims to solve the problems of high manufacturing cost, tough guide debugging, low vitality-saving effectivity and the like of a conventional hydraulic balance adjusting system. The variable-frequency water pump set controller, the chilly and hot source controllers and the water terminal controllers are subject control items and are linked with the master station controller by means of a discipline control bus to type a DCS pc community management system; the master station controller is used for receiving the corresponding tools operation info uploaded by each area management unit and sending a coordinated operation control instruction of the DCS pc community control system to each area management unit, in order that the DCS computer network control system, every area control unit and all tools operate in line with the rule of 'actual-time load monitoring and minimal cost'.
