Intelligent digital display temperature transmitter circuit

Abstract

The invention relates to an intelligent digital display temperature transmitter circuit. The temperature transmitter circuit comprises a power protective circuit, a power circuit, a temperature sensing component, a signal processing circuit, a main control circuit, a signal conversion circuit and a display circuit, wherein the power protective circuit is electrically connected with the power circuit, the power circuit is electrically connected with the temperature sensing component, the signal processing circuit, the main control circuit and the display circuit respectively, the temperature sensing component, the signal processing circuit, the main control circuit and the display circuit are electrically connected in sequence, and the signal conversion circuit is electrically connected with the main control circuit and the power circuit respectively. According to the temperature transmitter circuit, the power circuit is protected through the power protective circuit, the power circuitsupplies power to the temperature sensing component, the signal processing circuit and the main control circuit respectively, and the signal processing circuit processes a pressure temperature signaldetected by the temperature sensing component and outputs the pressure temperature signal to the main control circuit to determine a temperature value, so that a monitoring result is stable and reliable, and the anti-interference capability of the product is greatly improved; and the whole circuit is small in size and convenient to install and completely replaces an import product.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an intelligent digital display temperature transmitter circuit. Background technique [0002] There are already many types and styles in the design and development of intelligent digital display temperature transmitters, but the existing intelligent digital display temperature transmitters on the market often have many manufacturers with display parts on site, and even more manufacturers directly adopt Armored integrated temperature sensor, or temperature transmitter equipped with a secondary temperature instrument with communication. This kind of temperature transmitter has poor anti-interference ability, especially in places where the environment is relatively harsh, such as large motors, frequency converters and other interference, the monitoring stability is not good, and the circuit submission is large, which is inconvenient to install, which seriously affects th...
