Problems solved by technology

[0002] As we all know, in the current centralized heating system, most of the charging methods for heating are calculated according to the usable area of ​​the house. When the room temperature is too high, the user can only open the doors and windows to cool down or close the gate, which is a waste of energy and unscientific. It is harmful to the country and the country. Users are unfavorable. At present, my country has put forward the mandatory reform policy of "household metering and room temperature adjustment" in the heating reform. There is a kind of heat meter at home and abroad, which has large errors and large maintenance, and the measurement is seriously affected. Domestic and foreign The heat meters are all flow multiplied by temperature difference heat meters. The user's heating system must form a closed loop to measure the hot water flow. Because of the influence of water quality, the measurement is inaccurate. At present, there is a digital smart heat meter in China, which can be connected with a computer. Networking, automatic remote meter reading, and centralized management, but only one meter per household, so the cost is high and users are unacceptable

Embodiment 1

[0013] Take the single-pipe heating system as an example, such as figure 1 , shown in Fig. 2: the present invention is made of temperature sensor 1 and 2, transmission cable 3, 16 road analog switches 4, amplifier 5, A / D analog-to-digital converter 6, single-chip microcomputer 7, multi-user time-sharing liquid crystal display 8, interface 9 , a voltage converter 10, a remote transmission device 11 and a power supply 1.5V (DC) 12. The design principle of this heat meter is the same as that of the ZL03258472.5 heat meter. In the medium, the heat flow at any point is transferred along the direction of temperature, and the heat Q transferred per unit time is proportional to the temperature drop and the cross-sectional area perpendicular to the heat conduction direction, that is

[0014] Q=-λgradt F (W)

[0015] For unit area

[0016] q = Q F = - λ grad t ...

Embodiment 2

[0022] Take the double-pipe heating system as an example, such as figure 1 , shown in Fig. 3: design principle and working principle, advantage are all identical with embodiment 1.

Abstract

The invention relates to a multi-user time-division display energy-saving heat meter. It uses the temperature sensor 1, 2, the transmitting cable 3 to transmit the collected temperature parameter of each user to the 16 path analog switch 4, the it in order chooses different user by the setting order used time dividing method by the single chip machine 7 and sends it to the LCD 8 after the data processing of amplifier 5, the A / D transferor 6 and the single chip machine 7; the display time of each user is arranged by the single chip machine 7.

Description

Technical field: [0001] The invention relates to a heat meter, in particular to an energy-saving heat meter with multi-user time-sharing display. Background technique: [0002] As we all know, most of the charging methods for heating in central heating are calculated according to the use area of ​​the house. When the room temperature is too high, users can only open the doors and windows to cool down or close the gate, which is a waste of energy and unscientific. It is harmful to the country and the country. Users are unfavorable. At present, my country has put forward the mandatory reform policy of "household metering and room temperature adjustment" in the heating reform. There are a kind of heat meter at home and abroad, with large errors and large maintenance, and the measurement is seriously affected. Domestic and foreign The heat meters are all flow multiplied by temperature difference heat meters. The user's heating system must form a closed loop to measure the hot wate...
