System functions:
1: This system is a set of unmanned monitoring stations that can continuously collect and record temperature and humidity changes at monitoring points in real-time 24 hours a day. It displays and records monitoring information in real-time through various methods such as digital, graphic, and image, and can expand up to thousands of monitoring points.
2: Temperature and humidity alarm upper and lower limits can be set for each monitoring point, and an alarm signal can be automatically issued when abnormal data occurs at the monitored point. The alarm methods include on-site multimedia audio, sound and light alarm, network client alarm, telephone alarm, mobile SMS alarm, etc. Upload alarm information and conduct local and remote monitoring. The system can notify different duty personnel at different times;
3: The temperature and humidity monitoring software of the temperature and humidity monitoring system adopts a standard Windows 98/2000/XP fully Chinese graphical interface, which displays and records the temperature and humidity values and curve changes of each monitoring point in real time, collects historical data, * * values, * values, and average values of temperature data, accumulates data, and displays alarm screens.
4: The system can be expanded with various recording data analysis and processing software, which can draw bar charts, pie charts, perform curve fitting and other processing. It can output in TEXT format and also enter office software such as EXCEL spreadsheets for data processing.
5: The monitoring host can use monitoring software to print temperature data and operation reports at any time.
6: Powerful data processing and communication capabilities, utilizing computer network communication technology, allow any computer within the local area network to access the monitoring computer and view temperature and humidity changes at monitoring points online, achieving remote monitoring. The system can not only be monitored in the duty room, but also conveniently viewed and monitored by leaders in their own offices.
7: When the monitoring computer is turned off or damaged or paralyzed, the temperature and humidity data recorded by the temperature and humidity acquisition device for several hours has not been lost. It is stored in the acquisition device for easy retrieval, analysis, and viewing by temperature and humidity monitoring software.
8: Functional system: The data concentrator and touch screen tablet provide ports with signal output protocols, which can be connected to communication devices (GPRS DTU, etc.) for wireless transmission.
