Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] Example 1

[0034] This embodiment provides an easy-to-install embedded temperature and humidity controller for remotely monitoring and controlling the temperature and humidity of equipment boxes in a substation.

[0035] In this embodiment, Figure 1 As shown, the controller includes: multiple sets of temperature and humidity acquisition devices and temperature and humidity adjustment equipment, as well as background monitoring devices and multiple sensor signal collection terminals.

[0036] In this embodiment, Figure 1 As shown, each equipment mechanism box is equipped with: a preset number of temperature and humidity acquisition devices, a preset number of temperature and humidity adjustment devices; each sensor signal collection terminal is installed in the corresponding control cabinet; and the background monitoring device is installed in the control room.

[0037] In this embodiment, Figure 1 As shown, each sensor signal collection terminal LoRa is wirelessly connected to: a temperature and humidity acquisition device and a temperature and humidity adjustment device used in a preset area.

[0038] In this embodiment, Figure 1 As shown, a transmission center node and multiple transmission sub-nodes are provided between the background monitoring device and the sensor signal collection terminal; each transmission center node corresponds to a sensor signal collection terminal;

[0039] like Figure 1 As shown, the sensor signal collection terminal is connected to the corresponding transmission center node based on 485 to LoRa; each transmission center node is wirelessly connected to the transmission center node; the transmission center node is connected to the background monitoring device based on 485 to USB.

[0040] In this embodiment, combined with Figure 1 As shown, each sensor signal collection terminal acquires and stores in real time: the equipment mechanism box-temperature and humidity data collected by the temperature and humidity collection device within a preset range;

[0041] Combine Figure 1 As shown, the background monitoring device obtains the device mechanism box-temperature and humidity data stored in one or more sensor signal aggregation terminals, and combines the preset temperature and humidity prediction module and temperature and humidity thresholds to start the corresponding temperature and humidity adjustment device in a timely manner; It should be noted that the aforementioned temperature and humidity prediction module is constructed based on the background monitoring device and the temperature and humidity historical data;

[0042] Combine Figure 1 As shown, regarding the aforementioned “starting the corresponding temperature and humidity control equipment in a timely manner”, it is necessary to explain that:

[0043] The background monitoring device obtains temperature and humidity prediction data based on the temperature and humidity prediction module and the real-time temperature and humidity data; if the temperature and humidity prediction data exceeds the temperature and humidity threshold, the background monitoring device sends a debugging instruction to the corresponding sensor signal collection terminal; the sensor signal collection terminal receives the debugging instruction of the background monitoring device and uses the corresponding debugging temperature and humidity adjustment device to adjust the temperature and humidity of the corresponding equipment mechanism box until the temperature and humidity return to within the temperature and humidity threshold range.

[0044] In this embodiment, the structure of the temperature and humidity collection device is as follows: Figure 2 As shown in structure A, its transmission method is wireless Lora, its transmission frequency is 433MHz, its transmission distance is ≤500m, its power supply method is 3.6V lithium-ion battery, 4000mAh; its standby current is ≤2uA, and its working life is greater than 5 years; its sending methods include: 1) sending when the collected temperature / humidity fluctuation is ≥ the set value; 2) setting the time to force the current collected value to be sent regularly; its measurement range is: temperature -40 degrees Celsius to 125 degrees Celsius (accuracy is 1 degree Celsius), humidity 0% RH to 99.9% RH (accuracy is 3%); its shell is IP67 waterproof plastic shell, and its size is 90*50*42mm. The assembly diagram of the temperature and humidity acquisition device is as follows Figure 3 As shown, structure A represents a temperature and humidity collection device, and the temperature and humidity collection device is assembled by adhesive backing installation.

[0045] In this embodiment, the screen display of the sensor signal collection terminal is as follows: Figure 4 As shown, its communication interfaces include: LoRa (connected to the temperature and humidity acquisition device), RS485 (connected to the transmission center node); its communication protocol: Modbus (RTU) (connected to the transmission center node); its power supply is AC220V, and its power consumption: <5W.

[0046] In this embodiment, the structure of the LoRa signal relay device is as follows: Figure 5 As shown in Structure B, the LoRa signal relay device is installed in the control cabinet and control room to use LoRa signals for wireless communication; its transmission method is wireless LoRa, its transmission frequency is 433MHz, its transmission distance is ≤1000m, its communication interface is RS485, its communication protocol is Modbus (RTU), its power supply is AC 220V, and its power consumption is <2W;

[0047] In this embodiment, it's important to note that the sensor signal aggregation terminal, combined with the LoRa signal relay device, is installed in the corresponding control cabinet. This requires an AC 220V power source and a separate circuit breaker. The LoRa signal relay device's antenna is connected to the cabinet's vents and placed outside to ensure LoRa signal transmission. Signal relay devices in adjacent areas also serve as signal relays, allowing for self-organized network expansion and extension, ensuring network data security without incurring any network communication costs.

It has the characteristics of good scalability and ease of use.

[0049] For the easy-to-install embedded temperature and humidity controller described in the first embodiment, each sensor signal aggregation terminal is wirelessly connected to the temperature and humidity collection device and temperature and humidity adjustment equipment used in a preset area. Compared with the traditional "one-to-one temperature and humidity collection device and data transmission medium" temperature and humidity collection method, the number of "sensor signal aggregation terminals" as transmission media is reduced, thereby reducing the cost of temperature and humidity monitoring.

[0050] Each sensor signal collection terminal acquires and stores in real time: the equipment mechanism box-temperature and humidity data collected by the temperature and humidity collection device within the preset range; the background monitoring device acquires the equipment mechanism box-temperature and humidity data stored by one or more sensor signal collection terminals, and combines the preset temperature and humidity prediction module and temperature and humidity thresholds to start the corresponding temperature and humidity adjustment equipment in a timely manner; based on the above, it is possible to remotely perform selective temperature and humidity monitoring of the equipment mechanism boxes in the entire area. Compared with traditional manual scheduled inspections, it not only ensures the temperature and humidity monitoring coverage, but also reduces the difficulty of temperature and humidity monitoring.
