Temperature and humidity monitor monitoring software: This is the main software for system work. It patrols each terminal through the network, and the resulting temperature/humidity measurements are displayed on the PC's screen in real time. Since the contents of the 600 terminals cannot be simultaneously displayed on the screen of the PC, the monitoring software adopts a group display method and is divided into 10 groups. Each group of 60 terminals is displayed separately. The monitoring software patrols at the rate of one terminal per second. The monitoring data is stored in the hard disk every 10 minutes according to different terminal file names for future analysis. The monitoring software uses a one-to-many master-slave control method in the workflow. All terminals constantly monitor the temperature and humidity values, and the monitoring data is stored in the microcontroller RAM. Each data communication process is initiated by the master PC. The PC master issues the measurement and control commands and the terminal number. After receiving the instruction, the terminal sends the data in the RAM of the microcontroller to the master computer in the specified format. Inside the terminal, the F873 microcontroller uses interrupts to handle communication events. Normally, the main program of the single-chip microcomputer in the terminal continuously monitors the temperature and humidity and displays the LED. After the communication event occurs, the single-chip microcomputer immediately enters the interrupt service status. After the communication is completed, the single-chip microcomputer exits from the interrupt and returns to the main program to continue monitoring and display. Because the entire interrupt service communication process is short, only tens of milliseconds, the end user generally does not feel this process.
The temperature and humidity monitor is the same as browsing the webpage. You can use any browser to check the satellite data. Since all files are stored in a binary format in the database, it avoids the accumulation of a large amount of document data in different directories, and the query and management of access is convenient and quick. Only the dates and channels and areas need to be established to achieve historical and real-time data without any difference.
Real-time research advantages of temperature and humidity monitor
For human daily activities, the indicator of temperature and humidity is an important basic indicator for measuring the quality of the public environment and monitoring specific production and living environments. Aiming at the above activities, a real-time multi-point monitoring system for temperature and humidity monitoring was developed to require real-time monitoring of the temperature and humidity values ​​of hundreds of points within a certain range. The data was saved in real time, and the temperature and humidity changes at each measurement point were analyzed in real time. Provide monitoring services for industrial production sites, workplaces, and social and public events.
