Wireless Temperature Measurement Master Unit

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 computer 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 flexible 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, and displays the temperature change curves of monitoring points in real-time, analyzing them. An immediate alarm is triggered if the temperature overheats or rises sharply to the set alarm temperature, enabling the user to monitor the entire system's thermal condition without leaving their home.

The monitoring system is primarily 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 data from passive wireless temperature sensors within switch rooms.

The network layer consists of devices such as access controllers and access gateways, which are used to enable wide-area data transmission between the perception layer and the platform layer. The network 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 data 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, it actively pushes out early warning information.
