Problems solved by technology

[0005] Due to the long distance between the heat exchange station and the residential building, the heat will be exchanged with the surrounding environment and lost during the process of heating along the transmission pipeline to the residential building. Therefore, the heating obtained by the residential building closer to the heat exchange station is generally The temperature is higher. On the contrary, the heating temperature obtained by the residential buildings farther away from the heat exchange is lower, resulting in the temperature difference between the users at the end of the far heat source and the end of the near heat source, and it is impossible to provide uniform heating to the users of each building.

Embodiment 1

[0018] Such as figure 1 As shown, the heating supply control system includes a remote monitoring center 3, a plurality of control terminals 1, and at least one convergence point device 2, and the control terminal 1 and the convergence point device 2 establish a wireless link for communication through an ad hoc network; the convergence The point device 2 is connected to the remote monitoring center 3 through the RS485 bus or the RS232 interface or the RS422 interface or the USB interface or the M-BUS bus. The remote monitoring center 3 is installed in the heat exchange station; the main air intake road of each building is provided with an electric control valve 4, a temperature sensor 5 and a pressure sensor 6, and a control terminal is also installed beside the main air intake road of each building 1.

[0019] The control terminal 1 includes a microprocessor 11, an electric regulating valve control unit 12 for controlling the electric regulating valve 4, a signal acquisition ...

Embodiment 2

[0025] In this embodiment, on the basis of Embodiment 1, a relay 7 is also connected between the control terminal 1 and the convergence point device 2, which is more reliable than when the distance between the control terminal 1 and the convergence point device 2 is longer. communication to ensure the stability of the system.

Abstract

The invention discloses a control system for central heating supply, and the control system for central heating supply comprises a remote control centre, a control terminal and a rendezvous point device, the control terminal and the rendezvous point device build the wireless link for communication; the rendezvous point device is connected to the remote control centre; the air inflow main pipe for each building is provided with an electric adjusting valve, a temperature sensor, a pressure sensor and a control terminal; the control terminal comprises a microprocessor, an electric adjusting valve control unit, a signal collecting unit, a wireless communication unit and a storing unit, the electric adjusting valve control unit is connected to the coil of the electric adjusting valve, the signal collecting unit is connected to the temperature sensor and the pressure sensor; the heat exchanging station can collect the temperature and pressure of the gas supplying pipeline of the building in a remote mode and exactly adjust the electric adjusting valve in a wireless mode for balancing the temperature for the heat source far end and heat source near end and supplying the heat evenly. The cost for heat supplying system is low, the energy is saved and the consumption is reduced.

Description

[0001] technical field [0002] The invention relates to the technical field of automatic control, in particular to a heating supply control system. Background technique [0003] How to cope with global climate change is one of the important issues at present. Even subtropical regions may have low temperature weather, especially in northern my country, where there are more low temperature and freezing weather every year. In order to cope with the extremely cold weather, the general public will generally equip their homes with heaters In the north of my country, the central heating system is generally used for central heating, so the heating system is a common energy supply system in the north. [0004] In the heating supply system, each household in the residential building is equipped with a heating pipeline, and the heating from the heat exchange station is transported to each residential building through the heating pipeline, and then sent to each user's home. [0005] D...
