Referring to fig. 4, when the forehead temperature gun of this embodiment works, the core control chip sequentially switches between six modes, that is, an initial mode, a waiting mode i, a temperature measuring mode, a waiting mode ii, a recording mode, and a waiting mode iii, as follows:

1) in an initial mode, the control chip is powered on and performs self-checking, at the moment, a WiFi hotspot is established on a mobile phone of a worker and serves as a transmission source of a WiFi signal, the Ethernet module searches for the WiFi signal, after the WiFi signal is successfully added into the mobile phone and an IP address is obtained, pins 10 and 11 of the control chip output high levels, the LED I LED1 and the LED II LED2 are lightened, meanwhile, pin 12 of the control chip outputs PWM waves with a certain duty ratio, the buzzer BEEP sounds according to the frequency I, the process lasts for 1s, all pins 10, 11 and 12 of the control chip output low levels, the LED I LED1 and the LED II LED2 are extinguished, the buzzer BEEP stops sounding, and the control chip enters a waiting mode I. If the WiFi is not added to the Ethernet module of the control chip after the control chip is powered on, the 12 pins of the control chip output PWM waves with a certain duty ratio at intervals of 2s and continue for 1s, and the buzzer BEEP at intervals of 2s buzzes for 1s according to the frequency II to remind that the WiFi is not accessed. The control chip continuously searches wifi in the process, and the process continues until the control chip searches signals.

2) After entering the waiting mode I, the control chip waits for the short-press operation of the KEY I KEY 1. The forehead temperature gun is aimed at the forehead of a tested person by a worker, when the worker presses a KEY I KEY1, the level of an 8 pin of a control chip jumps from a low level to a high level, when the KEY I KEY1 is released, the level of the 8 pin of the control chip jumps from the high level to the low level, when the first jump is monitored, the control chip starts timing, and when the second jump is detected, the control chip stops timing. When the timing time is less than one second, the button I KEY1 is judged to be finished by one short pressing operation. After detecting the short-time pressing operation of the KEY I KEY1, the control chip enters a temperature measuring mode. In this state, the 10 pins of the control chip continuously output high level, and the light emitting diode I LED1 is continuously lighted. The control chip receives temperature data of the infrared temperature sensor, displays the data on the OLED display screen, and transmits the data to the network through the Ethernet module, after the data are successfully transmitted, the control chip outputs PWM waves with a certain duty ratio lasting for 1s at 12 pins of the control chip, the buzzer BEEP can buzz for 1s according to the frequency I, then the control chip enters a waiting mode II, 10 pins of the control chip output low level, and the LED I1 is turned off. If the data transmission is not successful, the control chip uploads the data again every 1s until the data is successfully uploaded. If the control chip detects the long-press operation of the KEY I KEY1 at any time in the temperature measurement mode and the waiting mode II, namely after the KEY I KEY1 is pressed, the level of an 8 pin of the control chip jumps from low level to high level, the control chip starts timing after the first jump is monitored, and after the KEY I KEY1 is released, the input level of the 8 pin of the control chip jumps from high level to low level, the control chip stops timing, the time is more than 1s, and the KEY I KEY1 is judged to finish the long-press operation. The control chip will immediately return to the waiting mode i and delete the data generated in the temperature measurement mode.

3) After entering the waiting mode II, the control chip waits for the short-press operation of the KEY II KEY2 (the principle is the same as that of the short-press operation of the KEY I KEY 1). After the staff presses the KEY II KEY2, the tested person reports 'name + district + house number'. When the short-time pressing operation of the KEY II KEY2 is detected, the control chip enters a recording mode. In this state, the 11 pin of the control chip continuously outputs high level, and the light emitting diode ii LED2 is continuously lighted. In the mode, audio information collected by the microphone micro is uploaded through the Ethernet module, when the data transmission is successful, the control chip outputs PWM waves with a certain duty ratio lasting for 1s at the 12 pins, and the buzzer BEEP rings for 1s according to the frequency I. If the data transmission is not successful, the control chip uploads the data again every 1s until the data is successfully uploaded. The audio information after successful uploading is subjected to voice recognition at the cloud end, the control chip downloads voice recognition content from the cloud end and displays the voice recognition content on the OLED display screen after uploading for 2s, the control chip enters a waiting mode III, 11 pins of the control chip output low levels, and the light emitting diode II LED2 is turned off. If the control chip detects the long-press operation of the KEY II KEY2 (the principle is the same as the long-press operation of the KEY I KEY 1) at any time in the recording mode and the waiting mode III, the control chip immediately returns to the waiting mode II and deletes the data generated in the recording mode.

4) And after the control chip enters the waiting mode III, the control chip continuously waits for 5s, and if the staff does not have key operation within 5s, the acquisition is completed. And the control chip enters a waiting mode I to wait for next acquisition.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
