STONE HMI ESP32 Line Count and Alarm

[caspar]

With the continuous development of a single-chip microcomputer, the counting equipment tends to be automatic. It needs an automatic technical device with real-time, high efficiency, and accuracy to meet the counting requirements of the modern production line. Through the design of esp32 MCU as the core processor to meet the above requirements, in addition to the application of infrared sensor and smoke alarm function, it has the characteristics of small size, strong function, high reliability, and high-cost performance.
The design idea of this application is that the infrared transmitting tube emits infrared rays, and the infrared receiving tube receives the infrared ray. When the infrared receiving tube is irradiated by infrared rays, the resistance will change, and the single-chip microcomputer can collect this change; so is the smoke sensor. When the smoke concentration in the surrounding environment fluctuates, it will produce a level change, and the single-chip microcomputer can also collect it, The system uses a stone TFT LCD serial port screen, which is very convenient to develop. It only needs to complete the communication through the serial port. The MCU naturally adopts esp32.
This application can help the production line to realize the automatic piece counting function, and has the function of fire recording. When there is a fire, the number of occurrences is recorded, and this function can expand the alarm function.

Project Overview
Here we do the production line counting application, after boot, stone TFT The LCD serial port screen will have a start interface. After a short stay, it will jump to the specified page 1 and display the time setting. At this time, it is necessary to set the current time. Another option is to have a record of the number of fires, which will be added one each time, which can be used as the basis for fire control on the production line. After the time setting is completed, it will be displayed on the next interface, and click OK Enter the set production target as the assessment basis. After setting, click OK to enter the counting interface. Here, the data uploaded to esp32 through the sensor, and then transmitted to the stone TFT LCD serial port screen through esp32. One will be added each time. The current output rate will be calculated according to the target quantity, and the data will be updated every time an object is detected.

The communication functions are as follows:

The serial port screen of stone TFT LCD realizes the function of button switching interface;
The serial port screen of stone TFT LCD realizes the function of an automatic jump when starting up;
The serial port screen of stone TFT LCD realizes time setting;
The serial port screen of stone TFT LCD realizes data variable distribution;
STONE TFT LCD serial port screen realizes serial command communication.
Modules required for the project:

STONE TFT LCD；
Arduino ESP32；
Infrared detection module;
④ Smoke detection module.
