NB-IOT intelligent temperature control integrated system

Abstract

The invention relates to an NB-IOT intelligent temperature control integrated system which comprises a radiator, an ultrasonic heat meter, an NB-IOT electric control valve, an indoor water inlet pipe and an indoor water return pipe. One end of the radiator is connected with the indoor water inlet pipe; the other end of the radiator is connected with the indoor water return pipe; the ultrasonic heat meter is installed on the indoor water inlet pipe; and the NB-IOT electric control valve is installed on the indoor water return pipe. The NB-IOT intelligent temperature control integrated system has the following beneficial effect that the arrangement and coverage of NB-IOT equipment in a signal blind region are implemented. The heat supply household metering and room temperature regulation and control integrated system integrates metering, data acquisition and processing, control and management, and is a solution designed by taking energy saving, consumption reduction, cost saving and automatic control as the starting points.

Description

technical field [0001] The invention relates to an NB-IOT intelligent temperature control integrated system, which belongs to the technical field of heating systems. Background technique [0002] At present, my country's heating energy consumption index is 3-5 times that of developed countries under similar climate conditions, and the heating effect is far inferior to other developed countries. Due to the backward form of my country's heating system, lack of control and energy-saving means, it generally operates under low load and low efficiency. The actual heating area is only about 40% of the equipment capacity on average, and energy waste is very serious. At the same time, there are still the following problems in my country's heating system: [0003] 1. The indoor thermal environment is poor. In developed countries, the indoor temperature is 22°C, while in my country it is only 16-18°C; [0004] 2. The heating quality is also very poor, and there is a serious imbalance...

AI Technical Summary

Problems solved by technology

[0003] 1. The indoor thermal environment is poor. In developed countries, the indoor temperature is 22°C, while in my country it is only 16-18°C;

[0004] 2. The heating quality is also very poor, and there is a serious imbalance between the water supply power and the heat power, which makes the room temperature uneven;

[0005] 3. The heating charging system is unreasonable, charging according to the area, and there is no temperature control equipment in the room, and users cannot adjust the room temperature. These all lead to users' lack of awareness of energy conservation and serious waste of heat energy;

[0006] 4. The existing wireless technology cannot well meet the needs of heat meters to automatically report data through wireless in terms of coverage and power consumption

[0008] 1. The NB-IOT electric control valve needs an external power line, and the installation and construction are cumbersome

[0009] 2. It needs to be wired to the intermediate data transmission equipment for data transmission, and the wiring is complicated

[0010] In addition, traditional control valves need to be opened and closed manually, which requires high labor costs. At the same time, the existing control valves are mainly cast, with low production efficiency, low cost, low intelligence, and inconvenient operation.

At the same time, the key to control the opening and closing of the control valve is the variable speed motor installed above the ball valve. The variable speed motor is connected to the valve stem. Due to the frequent rotation and movement of the valve stem, wear and tear will occur continuously, which will cause the valve to be damaged under long-term working conditions. The wear of the inner seal causes the position of the electric control ball to deviate, resulting in the failure of normal opening and closing. After this failure occurs, it cannot be quickly troubleshooted, and the operating cost is high
