Priority date (The precedence date is an assumption and isn't a authorized conclusion. The invention discloses an intelligent hydraulic balance control system system based mostly on a datum point tracking technique. The management gadget consists of: the system includes a foremost station controller, a variable-frequency water pump set controller, a chilly and heat supply controller and water terminal controllers. Each controller is linked with every corresponding machine. Each controller is a area control unit, and is connected with the master station controller to type a DCS pc network management system. The controller of the variable-frequency water pump set tracks probably the most unfavorable end, particularly the total load change of the system in actual time on the minimum price; while other controllers management the respective units to trace the respective finish load adjustments in real time at minimal price; below the coordinated management of the grasp station controller, all of the devices of the water circulation system operate in accordance with the rule of 'real-time load monitoring and minimal price', namely the intelligent operate of self-adaption and minimal power consumption.

Thus, the system is in an integrally optimized dynamic hydraulic steadiness state intelligently all the time, and the ideal purpose of supplying water on demand at the minimal price is achieved by every water use end. The invention relates to the sector of hydraulic balance management of a water circulation system. The water circulation system is widely applied within the production and life of workers and people, however the issue of hydraulic imbalance affecting the safety, the operation effectivity and the quality of the water circulation system is always plagued within the trade; the hydraulic imbalance is the phenomenon that every finish of the system does not have the function of supplying water in accordance with the need, so that the cold and sizzling of every end of the system are uneven, the security is lowered, the vitality consumption is increased, and the operation high quality is decreased; as a result of the typical reduction concept, linear considering, stacking and stacking built-in scientific paradigm and the nonlinear complicated water circulation system aren't matched in nature, the formed water circulation system will not be brought on by an inherent healthy structure.

The traditional technique for solving the hydraulic imbalance is to install a balance valve on a essential pipe and a department pipe of a water circulation system. There are two kinds of balancing valves: fixed flow sort steadiness valve and fixed strain kind stability valve. While the internal structure and the intrinsic operation rule of the water circulation system and the roles and capabilities of the steadiness valves in the system and iTagPro Product the modifications of the general efficiency of the system will not be quite clear for builders of the balance valves, the developed balance valves can clear up the problem of hydraulic steadiness, but carry other issues, iTagPro Product as shown in fig. 1 and 2, the stability valves are put in on each branch pipe, every primary pipe and each predominant pipe, the balance valves are vastly difficult, each balance valve is manually adjusted to the designed circulate by utilizing expensive particular devices, the process is sophisticated, the adjusted circulation is barely the designed worth but not the actual value, and the distinction of two values at completely different ends can be totally different, so that the accuracy of the circulation adjustment can be different; in the meantime, the fixed current and constant strain efficiency of the balance valve is modified by consuming 20% -30% of the conveying energy of the water pump, and the problems are opposite to the unique purposes of hydraulic steadiness vitality saving and operation high quality enchancment design, in order that popularization and software of the steadiness valve are restricted.

Therefore, the normal steadiness valve has advanced construction, very advanced structure for forming a hydraulic balance adjusting system, high manufacturing value, tough guide debugging, low energy saving effectivity and the like. The invention goals to offer an intelligent hydraulic balance control system gadget by a datum point tracking method, which aims to unravel the problems of excessive manufacturing price, tough guide debugging, low power-saving effectivity and the like of a conventional hydraulic balance adjusting system. The variable-frequency water pump set controller, the chilly and scorching supply controllers and the water terminal controllers are discipline control units and are related with the master station controller by a field management bus to type a DCS computer network management system; the master station controller is used for receiving the corresponding equipment operation info uploaded by each discipline control unit and sending a coordinated operation management instruction of the DCS computer network control system to every discipline control unit, so that the DCS pc community management system, every subject management unit and all gear function according to the rule of 'real-time load tracking and minimal price'.
