[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 6As shown, the first embodiment of the present invention provides a plug-in wireless temperature sensor comprising an upper cover 10, a lower cover 20, a power pin module 30, and a wireless temperature acquisition and transmission module 40. The power pin module 30 includes a power pin mounting base and a power pin mounted on the power pin mounting base. The wireless temperature acquisition and transmission module 40 is electrically connected to the power pin. The power pin mounting base is removably fixedly connected to the inner side wall of the lower cover 20, and the power pin extends outside the lower cover 20. The wireless temperature acquisition and transmission module 40 is removably fixedly connected to the inner side wall of the upper cover 10, and the upper cover 10 and lower cover 20 are covered. In this embodiment, the upper cover 10 and lower cover 20 are made of PVC (polyvinyl chloride) insulating and flame-retardant material, which is safe and lightweight. The power pin mounting base is fixed to the inner side wall of the lower cover 20 by screws. The wireless temperature acquisition and transmission module 40 is also fixed to the inner side wall of the upper cover 10 by screws. The power plug uses a standard 86-type three-flat head power plug for plugging into a 220V mains socket and is also used to secure the device. The wireless temperature acquisition and transmission module 40 can utilize existing functional modules, such as LoRa (Long Range Radio), WiFi (Wireless Fidelity), NB-IoT (Narrow Band Internet of Things), and 4G (the fourth generation mobile communication technology) wireless temperature acquisition and transmission modules, all of which are within the scope of protection of this patent.

[0032] Further, see Figures 1 to 6The plug-in wireless temperature sensor proposed in this embodiment has a wireless temperature acquisition and transmission module 40 that includes a temperature sensor, an MCU (Microcontroller Unit), a wireless communication module, and a built-in antenna. The MCU is connected to the temperature sensor and the wireless communication module, which are connected to the built-in antenna. The temperature sensor is used to collect ambient temperature. The MCU is used to wirelessly transmit the ambient temperature collected by the temperature sensor to a corresponding mobile terminal via the wireless communication module and the built-in antenna, allowing personnel to obtain real-time information about the indoor ambient temperature. Preferably, the temperature sensor is a digital temperature sensor, model DS18B20. The wireless communication module is a narrowband Internet of Things wireless communication module. The wireless communication module includes a wireless communication chip, model PAN3031. The wireless communication module includes a radio frequency switch chip, which is connected to the wireless communication chip and the built-in antenna, model CKRF2179MM26. The wireless temperature acquisition and transmission module 40 is electrically connected to the power pin via a power wire. The MCU is model HC32L130J8. The upper cover 10 and lower cover 20 snap together and are secured with screws for easy assembly. The plug-in wireless temperature sensor also includes a power module, which is connected to the power pins and the wireless temperature acquisition and transmission module 40. This module converts the mains power into a normal operating voltage for the wireless temperature acquisition and transmission module 40.

The wireless temperature acquisition and transmission module integrates an MCU, a narrowband IoT wireless communication module, a temperature sensor, and a built-in antenna. The MCU (microcontroller unit), or single-chip microcomputer, is responsible for the module's calculation, storage, digital-to-analog conversion, and control functions. The temperature sensor is responsible for collecting ambient temperature with an accuracy of 0.1°C. The narrowband IoT wireless communication module is responsible for wireless communication transmission, using the standard Mod-Bus serial communication protocol and a low-power dedicated IoT communication chip. The built-in antenna achieves data transmission gain, with a maximum stable communication transmission distance of 500 meters (unobstructed) or up and down through four floors. The wireless temperature collection and transmission module supports functions such as address modification, reading and writing temperature offsets, and reading and writing measured temperatures. A single wireless collector can collect data from up to 255 wireless temperature sensors, enabling efficient, long-term temperature collection over a wide range of environments. The module also incorporates a conflict avoidance mechanism. Upon receiving a signal, it automatically delays its response by a random amount, preventing conflicts when simultaneously collecting data from multiple modules within the network.

[0033] like Figures 1 to 6 As shown, the first embodiment of the present invention proposes a plug-in wireless temperature sensor, the working principle of which is as follows:

[0034] The power module uses a 200V-3.3V AC-DC power module to convert 220V mains electricity into 3.3V to power the wireless temperature acquisition and transmission module 40.

[0035] The temperature sensor in the wireless temperature acquisition and transmission module 40 is used to collect the ambient temperature; the MCU is used to wirelessly transmit the ambient temperature collected by the temperature sensor to the corresponding mobile terminal through the wireless communication module and the built-in antenna, so that the relevant personnel can understand the indoor ambient temperature in real time.
