Embodiment Construction

[0009] : The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0010] After plug wire 1 is inserted into mains 27, the circuit works normally. At this time, LED indicator 8 is on, LCD1602 liquid crystal will display the current temperature value, preset minimum temperature alarm value, preset maximum temperature alarm value, buzzer 19 does not The buzzer alarm indicator 21 does not flash, and the electrical appliance 26 with a rated voltage of 220V does not light. When the external environment temperatu...

Abstract

Provided is a main chip circuit control module for a temperature real-time monitoring alarm control system. The invention relates to a relay control circuit and an MAX232 serial communication circuit. A direct current circuit part of a relay circuit is communicated with a main control circuit of a single-chip microcomputer, and a guillotine circuit of a relay is communicated with a mains supply. An extraction circuit of temperature signals, an alarm circuit and a temperature value display circuit are communicated with the STC52 single-chip microcomputer of a main control chip. An LCD1602 liquid crystal display is connected with the STC52 single-chip microcomputer through a resister pack to finish corresponding data display tasks. A DS18B20 temperature sensor is connected with the STC52 single-chip microcomputer to be used for collecting temperature information. An LED lamp first is in parallel connection with a buzzer and is connected with an emitting electrode of a PNP triode to be used for finishing light-emitting warning and light warning tasks. The STC52 single-chip microcomputer is connected with a 9-pin serial port through an MAX232 chip to finish tasks of communication with a computer terminal. An accompanying diagram is a logic structure diagram. The main chip circuit control module is formed by 11, 24 and 25 in the diagram.

Description

[0001] Technical field: computer and network technology [0002] The invention relates to the field of computer and network technology, in particular to information collection technology. Background technique: [0003] In the existing technology industry, there are many types of products for real-time monitoring of temperature data, but most of them collect some fixed temperature information, and cannot be synchronized with the computer terminal in time.
