Method, device and system for measuring temperature

Abstract

The invention belongs to a communication technology, and provides a method, a device and a system for measuring the temperature. The method comprises the steps of outputting an audio signal to a power supply management unit through an audio interface by a terminal device after a user temperature measuring command is received; receiving and processing the audio signal by the power supply management unit and outputting direct current voltage; triggering a processing unit to receive a voltage signal output by a temperature sensor after the direct current voltage is output by the power supply management unit, and obtaining target temperature data mapped by the voltage signal; converting the target temperature data into a binary code, adding a check code for the binary code, encapsulating the binary code into a data package, and sending the data package to the terminal device through a microphone; checking the data package after the data package is received by the terminal device, and displaying data passing the check. According to the method, the device and the system, disclosed by the invention, a power supply unit is not needed to be additionally arranged, the starting of a whole temperature measuring process can be triggered through the output of the audio signal, the whole temperature measuring process can be ended when the output is stopped, the device cost is reduced, and a battery does not need to be frequently replaced or charged.

Description

technical field [0001] The invention belongs to communication technology, and in particular relates to a temperature measuring method, equipment and system. Background technique [0002] At present, the existing temperature measurement equipment must communicate through analog signals when connecting with the terminal equipment through the audio interface. The temperature measuring equipment is equipped with a power supply unit to supply power to the temperature measuring equipment. The whole equipment depends on the power supply of the temperature measuring equipment itself when running. The normal use of temperature equipment, and at the same time, when designing and producing temperature measurement equipment, it is necessary to reserve a specific space for placing batteries, which makes the temperature measurement equipment too large, increases the weight of the equipment, and is inconvenient for users to carry. Contents of the invention [0003] The purpose of the em...
