Abstract
The invention relates to a single-chip microcomputer temperature control system. The single-chip microcomputer temperature control system includes a temperature range setting module, a temperature detection module, a temperature rise control module, a temperature information acquisition module, a recording module, a temperature information display module and an overtemperature alarm module. The temperature control and acquisition system is mainly used for carrying out temperature real-time monitoring on a specified region or space, acquiring and recording temperature information in real time, and can realize automatic and intelligent control and regulation of temperature, so as to ensure that the temperature is constantly kept in an expected range. The system of the invention has the advantages of low cost and convenience in use and expansion, and can be widely used in people's daily life, industrial and agricultural production and the scientific research field and provide references for extensive and deep application.
Description
Technical field
The invention belongs to automatic control technology field, be specifically related to a kind of SCM Based temperature control system.
Background technology
In industrial control process, there is higher requirement in the such as field such as Aeronautics and Astronautics, oil to temperature.In reality is measured and is controlled, how to ensure quickly in real time temperature to be sampled, guarantee the correct transmission of data, and measured temperature field can be controlled more accurately according to being actually needed, be one of current temperature control system major issue of needing urgently to pay close attention to and give to solve.
Summary of the invention
Technical problem: the problem existed for above-mentioned prior art, the present invention provides a kind of SCM Based temperature control system.
Technical scheme: the present invention relates to a kind of SCM Based temperature control system, it is characterised in that: include the setting module of temperature-control range, temperature detecting module, control module of heating, temperature information acquisition module, logging modle, temperature information display module and overtemperature alarm module；Temperature controls to be primarily directed to formulate region with acquisition system or space carries out the monitoring that temperature is real-time, in real time acquisition and recording temperature information, and realizes the control of the automatic intelligent to temperature, regulation, in guaranteeing the scope that temperature is always held at estimating.
The temperature in controlled device region can be obtained by the sensing of One Wire digital temperature sensor, by AT89S51 single-chip microcomputer, the voltage signal that digital temperature sensor exports is sent to portable computer by serial ports again, voltage signal is converted to temperature signal by portable computer upper computer software, stamp time labelling, show in real time and store.
The method have the advantages that
1, present system is the most with low cost but also use and extend conveniently, can be widely applied to people's daily life, industrial and agricultural production and field of scientific study, provides reference for application extensively and profoundly.
2, the feature that present system precision is high, highly reliable, flexible operation, extensibility are strong, can be widely applied to industrial control field.
Accompanying drawing explanation
Fig. 1 is present system structured flowchart.
Fig. 2 is temperature signal regulation circuit theory diagrams in the present invention.
Fig. 3 is working-flow figure in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment further illustrates technical scheme.
As it is shown in figure 1, a kind of SCM Based temperature control system, including setting module, the temperature detecting module of temperature-control range, control module of heating, temperature information acquisition module, logging modle, temperature information display module and overtemperature alarm module；Temperature controls to be primarily directed to formulate region with acquisition system or space carries out the monitoring that temperature is real-time, in real time acquisition and recording temperature information, and realizes the control of the automatic intelligent to temperature, regulation, in guaranteeing the scope that temperature is always held at estimating.
The temperature in controlled device region can be obtained by the sensing of One Wire digital temperature sensor, by AT89S51 single-chip microcomputer, the voltage signal that digital temperature sensor exports is sent to portable computer by serial ports again, voltage signal is converted to temperature signal by portable computer upper computer software, stamp time labelling, show in real time and store.
As shown in Figure 2, if temperature signal regulation main circuit is designed according to the feature of K-type thermocouple, owing to K-type thermocouple uses temperature range to be-200～1200 DEG C for using temperature range, its output voltage signal is mV level, therefore, signal conditioning circuit includes signal amplification circuit, filter circuit and cold junction compensation circuit.
As it is shown on figure 3, serial communication modular mainly carries out the communications of data and control command with host computer, host computer sends out a command word every 50ms, it is desirable to data uploaded by single-chip microcomputer；When parameters such as temperature controlling range to be revised, host computer first sends out a command word, send out data again, according to command word and data, serial communication modular first determines whether that the temperature range data of amendment are the most reasonable, if error in data, then to host computer feedback error information, if rationally, then complete to control acquisition operations accordingly.
