The remote control terminal analyzes the received heating quantity information and can send control instructions to the heating control valve body through the console therein to open or close the heating control valve body with the corresponding number of each household.

[0043] See also Figures 1-8The control console comprises a cabinet body 1 and a display screen 2 arranged on the cabinet body 1, the display screen 2 is used for displaying the analysis result of the heating amount information sent by the real-time monitoring unit, and further comprises:

[0044] A plurality of rolling wheels 4 are arranged at the bottom of the cabinet body 1 and are used for moving the cabinet body 1 and changing the working position of the remote control end, and a plurality of supporting legs 5 are further arranged at the two sides of the cabinet body 1, the supporting legs 5 are connected with a supporting mechanism arranged at the side of the cabinet body 1;

[0045] A protective plate 3 is movably arranged above the cabinet body 1 and is attached to the display screen 2, the protective plate 3 is connected with a lifting driving mechanism arranged on the cabinet body 1, and a mounting cavity 6 is arranged at the bottom of the protective plate 3, and a rolling cleaning mechanism is arranged in the mounting cavity 6;

[0046] The supporting mechanism can drive the plurality of supporting legs 5 to descend and promote the plurality of rolling wheels 4 to ascend, at the same time, the supporting mechanism drives the lifting driving mechanism to drive the protective plate 3 to ascend, so that the shielding state of the protective plate 3 to the display screen 2 is removed and the rolling cleaning mechanism performs the cleaning action on the display screen 2.

[0047] Specifically, the control console is divided into two modes:
