Background
The existing regulating method for building heat supply comprises the following steps:
(1) and quality adjustment, namely, only changing the water supply temperature of the network at the heat source along with the change of the outdoor temperature, and keeping the designed flow constant for the circulating flow of the network. The pipe network leveling is time-consuming and labor-consuming, the return water temperature is mainly seen, the adjustment is lagged, the waste is caused, and the tail end of the outer pipe network is lack of a regulation and control means.
(2) The quantity is adjusted, the flow of the network is rapidly reduced along with the rise of the outdoor temperature, so that the heating system can generate serious vertical heat imbalance, meanwhile, the flow of the network is continuously changed along with the change of the outdoor temperature in the actual operation, the operation technology is complex, the hysteresis is large, and the time consumption is long. A heat dissipation and temperature rise link exists between the water temperature and the room temperature, and under the combined action of variable weather conditions and different building heat storage conditions, the accuracy of room temperature response is difficult to guarantee according to the empirically determined water temperature setting, so that the room temperature of a user is often higher or lower.
The existing heating system is backward and lacks of control means. The heating system only has simple adjusting means, and the phenomena of horizontal maladjustment and vertical maladjustment are serious.

The technical problems to be solved by the invention are as follows: the intelligent energy-saving control system for building heat supply is provided to solve the problem of rapid adjustment by using heat source adjustment and tail end direct control.
In order to solve the existing technical problems, the technical scheme adopted by the invention is as follows: the intelligent energy-saving control system for building heat supply comprises a sensor, an intelligent regulating valve, a building controller, a cloud server and a terminal server, wherein the intelligent regulating valve is installed on a water return pipeline of a building pipe network; the building controller is connected with the intelligent regulating valve and the sensor and is responsible for uploading information of the intelligent regulating valve and the sensor to the cloud server and controlling and executing a control strategy issued by the cloud server of the intelligent regulating valve; the cloud server is used for receiving the control command of the terminal server and the information uploaded by the building controller and issuing a generated control strategy to the building controller; and the terminal server is used for modifying the differentiated control requirements of the heat supply tail end of the building.
Meanwhile, the invention also discloses a control method of the intelligent energy-saving control system for building heat supply, which is divided into a constant temperature control mode, a coordination control mode, a remote network control mode and a manual control mode, and is characterized in that:
the constant temperature control mode is that a cloud server control strategy is set through a terminal server according to outdoor weather temperature change and a user activity rule, and an intelligent adjusting valve of a building is dynamically adjusted through a building controller to provide heat, so that the indoor temperature of a user is basically constant;
the coordination control mode is that a heat supply area is divided into a high-temperature area, a low-temperature area and a normal area through a cloud server, all buildings in each area are numbered, and all buildings are coordinated according to a well-programmed work sequence diagram according to the heat supply condition of each area, so that the differentiated distribution of heat is realized;
the manual control mode realizes the functions of manual flow regulation and heat regulation by manually regulating the parameters of the heat supply time and the valve opening of the intelligent regulating valve;
the remote network control mode is that remote service software is installed on a computer capable of surfing the internet, so that the operation parameters of each device can be monitored and controlled at any time, and the timeliness and accuracy of regulation and control are realized.
The intelligent energy-saving control system for building heat supply is set and controlled according to outdoor weather temperature change and user activity rules, dynamically adjusts the heat supply amount of the building, and enables the indoor temperature of a user to be basically constant. The phenomenon that a plurality of people in one building are overheated and a plurality of people are not hot is avoided, so that people can work and live in a warm environment. The heat supply of the building is changed from the original distribution mode to the demand-based access mode, so that the balance of the building without under supply and over supply is achieved, and the load heating area can be increased by 15-30%.
Advantageous effects
The invention uses heat source adjustment and tail end direct control to realize rapid adjustment; the triple adjustment of time, temperature and flow is introduced, so that the method is more accurate; and the energy is saved by performing differentiation adjustment.
(1) And a heating regulation and control mode of dynamic heat regulation is realized. The heat supply of the system changes with the change of the outdoor temperature at every moment, the outdoor temperature rises, the heat supply correspondingly reduces, and a dynamic heating state according to the requirement is kept, otherwise the same is true. The system heat supply quantity is matched with the heat supply requirement, and heat is supplied according to the requirement, namely more heat is required and more heat is supplied, and less heat is required and less heat is supplied.
(2) The problem of hydraulic balance of a pipe network is effectively solved. The heat supply of the building is changed from the original distribution mode to the demand-based access mode, so that the balance of the building without under supply and over supply is achieved, and the load heating area can be increased by 15-30%.
(3) The application of the building constant temperature regulating system increases the circulation flow of the pipe network and relieves the phenomenon of pipe network imbalance. Because the buildings are not put into the water supply system at the same time, the water supply flow at the same time is reduced, and the system resistance is correspondingly reduced, so that the flow of the outer pipe network is increased by 5-20%, the temperature difference of the supply water and the return water is reduced, and the terminal hydraulic imbalance with poor circulation is relieved.
