Automatic range-measuring control device of radiator

Abstract

The invention discloses an automatic range-measuring control device of a radiator. The automatic range-measuring control device of a radiator includes a radiator body on a housing and radiating holesin the housing, and also includes a temperature sensing module, an infrared range-measuring circuit, a pre-amplification circuit, a control circuit and a display circuit, wherein the temperature sensing module is used for obtaining the current temperature of the housing; the infrared range-measuring circuit is used for detecting a human body in the area where the housing is to obtain an analog signal, and then the analog signal is amplified by the pre-amplification circuit and then is input into the control circuit; the control circuit is used for obtaining the range value according to the received amplified human body analog signal, and controlling the display circuit to display the current temperature of the housing according to the range value; and the pre-amplification circuit includesfirst to fourth capacitors, first to fourth resistors, a first amplifier and a second amplifier. The automatic range-measuring control device of a radiator utilizes the simple circuit structure to realize two-stage amplification effect, can effectively suppress the noise in the circuit, can intelligently realize range-measuring and prompting, and can improve the safety.

Description

technical field [0001] The invention relates to an automatic ranging control device for a radiator, belonging to the technical field of heating devices. Background technique [0002] The radiator is a kind of heating equipment mainly for heating. It is mainly used in the northern regions where the winter is cold, and it has the function of keeping warm. In the past, cast iron radiators were often used, but now radiators with more materials have been developed. [0003] Cast iron radiators have gradually withdrawn from the market stage. New radiators such as steel radiators, copper-aluminum composite radiators, and aluminum radiators are superior to cast iron radiators in terms of material and manufacturing process, and have become the most mainstream in the market. Radiator. From the aspect of production, the production materials of steel heat sinks are easy to obtain, can be reused, the production conditions are good, and the operation is pollution-free. It has become a n...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an automatic ranging control device for radiators to solve the problem that when the existing radiators are in use, the temperature of the shell is too high due to heat dissipation, and when the human body approaches It cannot play the role of distance measurement and display reminder, which makes the shell easy to touch the human body and cause burns, which leads to the safety hazard of the shell
