Non-contact automatic temperature measurement system and method based on wireless charging

Abstract

The invention discloses a non-contact automatic temperature measurement system and method based on wireless charging. The non-contact automatic temperature measurement system comprises a temperature measuring device, an upper computer and a power supply device, wherein the temperature measuring device is in circuit connection with the power supply device and is in communication connection with theupper computer; the temperature measuring device further comprises an infrared sensor and a signal transmitting module; the signal transmitting module further comprises a single-chip microcomputer and a wireless communication sub-module; and the single-chip microcomputer is in communication connection with the infrared sensor, the wireless communication sub-module and the upper computer. When a person passes by, a generator is treaded to generate electricity to provide electric energy for the temperature measuring device, the infrared sensor starts to collect temperature and transmits the temperature to the single-chip microcomputer, and the temperature is transmitted to the upper computer through the wireless communication sub-module; after the to-be-measured person leaves, the treadingtype generator stops supplying power, and the temperature measuring device is dormant; and a buzzer, an LED display screen and a battery are omitted, energy and manufacturing cost are saved, externalpower supply is not needed, the application scene is wider, manual control is not needed in the temperature measurement process, and labor cost is saved.

Description

technical field [0001] The invention relates to the field of temperature measurement systems, in particular to a non-contact automatic temperature measurement system and method based on wireless charging. Background technique [0002] In the context of the current epidemic, the thermometer has become an indispensable and important prop in the epidemic prevention war. Compared with the usual mercury thermometers and electronic thermometers, infrared thermometers that can measure body temperature in a few seconds are more popular. During the epidemic, we can often see staff holding a forehead temperature gun, measuring the forehead of the person who wants to pass, and the temperature result can be obtained within a few seconds. This forehead thermometer is an infrared thermometer. [0003] The infrared thermometer is mainly composed of the following modules: shell, liquid crystal display, infrared sensor, main control board, buzzer, battery. All objects with a temperature h...

AI Technical Summary

Problems solved by technology

[0004] The currently used temperature measuring devices have the following problems: manual control is required, power consumption is large, and the circuit is not simple enough

At present, there are two main types of infrared thermometers on the market for rapid measurement in public places: the most common is the hand-held forehead thermometer. The problem with this device is that it is battery-driven, and the power cannot be maintained for a long time. For the epidemic prevention work that must be vigilant at all times It is undoubtedly a big disadvantage for personnel

and the need for manual control also limits its use

The second type is a rechargeable thermometer placed on the counter. The temperature sensor of this type of thermometer is quite different from the first type: the infrared sensor of the forehead gun only works when the button is pressed, which is relatively energy-saving. , while the counter type needs to be turned on all the time, the infrared sensor is always in the working state, and the power consumption is very large
