Passive wireless temperature sensing sensor

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

 The monitoring system is primarily composed of three components: 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 transmits 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. Typically, the network layer employs mature technologies like power wireless private networks, power APN channels, and power fiber networks, offering 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, and upon detecting abnormal signals, actively pushes out early warning information.
