Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings.
[0040] The main parameters of the present invention depend on the clock chip and the temperature sensor. The system specifically includes a calendar clock module, a temperature detection module, a key module, a display module, and the like.
[0041] The DS1302 chip is used to realize the real-time calendar clock function. The chip provides information including seconds, minutes, days, months, years, etc. The leap year can be adjusted by itself, and it is connected to the pins of the single-chip microcomputer through three wires for data transmission. And use DS18B20 sensor to collect temperature value for processing and conversion and A / D signal conversion. The temperature data is obtained through the DS18B20 temperature sensor, which is powered by an external vehicle power supply. 16 common-cathode LED digital tubes managed by two HD7279s...

The invention discloses a vehicle-mounted calendar clock and temperature measurement system based on a single-chip microcomputer, relates to a vehicle-mounted electronic display system, and designs an intelligent vehicle-mounted calendar clock and temperature measurement system by taking an AT89S52 single-chip microcomputer as a core. The core function of the vehicle-mounted calendar clock and temperature measurement system is to realize the functions of accurate operation and temperature measurement of the calendar clock. Parameters are transmitted mainly depending on a clock chip and a temperature sensor. The system mainly comprises a calendar clock, a temperature detection part, keys, a display part and the like. According to the system, the real-time display function of a clock is achieved through the clock circuit chip, environment temperature collection and A / D signal conversion are achieved through the temperature sensor, and the environment temperature and the A / D signal are sent to a nixie tube to be displayed through the single-chip microcomputer. The system can rapidly detect and reflect on the nixie tube, the measurement precision is + / -0.5 DEG C, the measurement precision is high, reading is convenient, more daily parameters are provided for drivers and passengers, and various information needing to be known at any time in life is facilitated.
Description
technical field [0001] The invention relates to a vehicle-mounted electronic display system, in particular to a vehicle-mounted calendar clock and temperature measurement system based on a single-chip microcomputer. Background technique [0002] Single-chip electronic products have entered the "home of ordinary people", and now in the application field of electronic information, designers can realize more abundant functions in a small area. [0003] In daily life, although people have no special requirements for the accuracy of temperature measurement, they also put forward new requirements for real-time reflection of ambient temperature. [0004] For example, "Single-chip microcomputer-based temperature alarm" (Liu Wenjing, Electronic Test, 2020(03):5-7) [1]. [0005] Ordinary temperature measurement equipment cannot meet people's requirements for real-time reflection of temperature, and it is even more necessary to design an ideal temperature measurement system.
