Abstract
The working environment of equipment has a great impact on the performance of equipment; therefore, it needs to be monitored and managed effectively. Based on the Internet of things (IoT), this study analyzed the monitoring of the campus network equipment environment. A monitoring system was designed, the design methods of software and hardware were analyzed, and the system was tested. The test results showed that the sensor used in the system had high accuracy, the temperature error was ± 0.5 ℃, the humidity error was within 0.5% RH, the data transmission performance was good, the transmission delay was between 8 ms and 9 ms, and the average packet loss rate was 0.7%. The test results verify the effectiveness of the designed system, and the system can be popularized and applied in the actual campus network.
Highlights
With the development of technology, the way of information acquisition has developed from manual to automatic
Jaco et al [12] designed a vehicle positioning system combining radio frequency identification (RFID) technology with a global system for mobile communication (GSM) technology, which obtained a reading range of about 31 cm in the lowfrequency communication range
A complete Internet of things (IoT) mainly includes three parts: (1) perception layer: it takes equipment such as a single-chip microcomputer as the terminal node, carries various sensors, and configures the communication module to realize the communication between nodes, and it provides data to the upper later via the hardware interface; (2) network layer: it uploads the data obtained by the hardware interface to the application center through communication technology or transmission control protocol/internet protocol (TCP/IP) port; (3) application layer: it integrates technologies such as database and uses the interface provided by the lower layer to realize the control of the terminal node
Summary
With the development of technology, the way of information acquisition has developed from manual to automatic. Ray et al [13] proposed a thermal comfort index measurement system based on IoT, which intelligently integrated sensors and cloud services. They found that the system realized heterogeneous network communication and low power consumption, showing good performance. Based on the IoT, this study designed a campus network equipment environment monitoring system, which realized the collection and monitoring of equipment environment data and the intelligence and informatization of network equipment environment management through ZigBee and sensor technology. 2 Design of environment monitoring system for campus network equipment based on IoT
