Embodiment 1

[0029] A teaching and training system based on a perpetual calendar temperature-humidity single-chip microcomputer, including a single-chip microcomputer, a system clock module, a temperature and humidity sensor module, a key input module, a communication interface module, a calendar clock module, a digital display module, a display driver module, an alarm module and PC, the system clock module, the temperature and humidity sensor module, the button input module, the communication interface module, the calendar clock module, the display driver module, and the alarm alarm module are respectively connected to the Single-chip microcomputer, the display driver module is connected to the digital display module, the PC is connected to the communication interface module, and the teaching and training system also includes a PCB experiment board, the single-chip microcomputer, the system clock module, the calendar The clock module, the temperature and humidity sensor module, the button ...

Embodiment 2

[0037] According to the teaching and training system described in Embodiment 1, the difference is that the desktop computer is connected to the communication interface module through a 3-wire serial cable, and the notebook computer is connected to the communication interface module through a USB-to-serial cable.

Embodiment 3

[0039] According to the teaching and training system described in Embodiment 1 or 2, the difference is that the calendar clock module integrates a trickle current charging circuit inside, and the calendar clock module is externally connected to a button backup battery.

[0040] The advantage of the design here is that the counting year of the calendar clock module reaches 2100, and after the date and time are set correctly, it has an automatic leap year compensation function; the calendar clock module is connected with a button backup battery, and the training system The time-of-day module clock continues to run without loss of time-of-day information.

Abstract

The invention relates to a singlechip microcomputer teaching training system based on a perpetual calendar hygrothermograph. The singlechip microcomputer teaching training system comprises a singlechip microcomputer, a system clock module, a temperature and humidity sensor module, a key input module, a communication interface module, a calendar clock module, a digital display module, a display driving module, an alarm module, a PC and an experimental PCB, wherein the singlechip microcomputer, the system clock module, the calendar clock module, the temperature and humidity sensor module, the key input module, the communication interface module, the digital display module, the display driving module and the alarm module are welded on the experimental PCB. The singlechip microcomputer is high in accuracy, high in reliability, economical, practical and low in cost, is used for daily life and also serves as an item set for singlechip microcomputer training teaching; a student plugs corresponding components according to component mark numbers and attribute values on the experimental PCB and then performs welding, so that the product manufacturing ability and the software / hardware research and development ability of the student are trained.

Description

technical field [0001] The invention relates to a teaching and training system based on a perpetual calendar temperature-humidity single-chip microcomputer, which belongs to the technical field of microcomputers. Background technique [0002] LED digital display perpetual calendar is widely used in various industries of daily life because it is not limited by the influence of daylight. In order to reduce costs, modern LED digital perpetual calendars are developing towards dedicated chips, that is, date, time, temperature, humidity, and display drivers are integrated on one chip, thereby reducing the production process and shortening the production cycle. Today's digital perpetual calendar system has the advantages of small size, low power consumption, accurate timing, stable performance, convenient maintenance, accurate travel time, and convenient portability. [0003] However, due to the confidentiality of its technology and the non-disclosure of the program, the dedicated...
