Wireless Temperature Sensing Sensor

The single-chip microprocessor controlled by the wireless temperature sensor converts the temperature of the measured device into a digital signal, which is then transmitted to the receiver via a wireless transmitter-receiver module. The microprocessor displays the collected temperature information on an LCD screen and uploads it to a PC or mobile device for real-time monitoring via a 485 communication module. Multiple wireless temperature sensors can be distributed within a straight-line distance of 300 meters from the receiver, allowing for the addition, deletion, or movement of temperature measurement terminals within the effective communication range. The control center's computer software monitors the temperature changes of each point in real-time. The temperature monitoring computer collects operational temperature data from the temperature measurement communication terminals, stores it in a database for long-term preservation, displays the temperature change curves of monitoring points in real-time, and analyzes them. Immediate alerts are triggered if the temperature overheats or rises sharply to the set alarm temperature, enabling the control of the entire system's thermal condition without leaving home.

The monitoring system is mainly composed of three parts: the perception layer, the network layer, and the platform layer.。

The perception layer is further divided into two parts: the sensor layer and the monitoring receiver.

Ø  The temperature sensor collects the cabinet node temperature and uploads the data to the monitoring receiver via wireless transmission.

Ø  The monitoring receiver aggregates, performs edge computing, and uploads passive wireless temperature sensor data from within the switch room.

The network layer consists of devices such as access controllers and access gateways, designed to facilitate wide-area data transmission between the perception layer and the platform layer. This layer typically employs mature technologies like power wireless private networks, power APN channels, and power fiber networks to provide high-reliability, high-security, and high-bandwidth transmission channels.

The platform layer is used for managing, coordinating, and monitoring passive wireless temperature sensors and monitoring receivers, as well as for displaying, storing, and managing monitoring data. It features certain data analysis and diagnostic capabilities, actively pushing warning messages upon detecting abnormal signals.
