Intelligent Temprature And Humidity Control System Design Based On SCM

With the rapid development and popularization of science and technology, more and more high performance equipment, all walks of life is becoming more and more high to the requirement of temperature and humidity. In order to solve the traditional temperature and humidity test in the past mainly based on human, rely on artificial turn on each other, artificial circuit to check the way to measure and record the environmental conditions such as the mode of information, avoid many of the catastrophic accidents caused by human factors, solve the problem of low efficiency for talent make full use of, make the measurement more scientific, in this paper, design a set of convenient and high precision measurement and control system.In this paper, by adopting single chip microcomputer as main controller in the system, and use SHT10 temperature and humidity sensor to collect the temperature and humidity in warehouse data, and will be collected after the analog signal by A/D conversion, sent to the main controller is analyzed to realize the monitoring of the warehouse temperature and humidity are appropriate. Finally, this system is applied to the GSM warehouse temperature and humidity control, when the measurement and the warehouse temperature and humidity value resulting from the conversion is improper, will produce a warning, alarm through TC35 GSM module and send text messages to the user, so that users can get the information in time and make the appropriate processing operations. It effectively improved the efficiency and accuracy of measurement and control, realized the support the remote control of the warehouse.This system is designed by four modules, including temperature and humidity acquisition module, the central control module, control module and sending alarm command sending module. Main function is to analyze the temperature and humidity data collected, and judge according to the results of the analysis to perform the operation, so as to realize the precise detection of temperature and humidity of warehouse and timely adjustment, and send the alarm to the user, when the user deems it necessary, can be forced to switch the external control system, thus to realize the effective control of temperature and humidity in the warehouse.In this article, we use the STC89C52 as the SCM, It is through the C language programming to achieve the measurement data analysis and processing. Temperature and humidity acquisition using SHT10 sensors, The alarm is sent by GSM module adopts the TC35 module, due to the GSM network on a global scale to achieve the networking and roaming, need not to form a special communication network, so for the traffic system to design not quite, choose a short message based on GSM network data communication is optimal.
