Description

A fire prevention electrical protection device and method based on the Internet of Things Technical Field

[0001] This application relates to the field of electrical protection technology, and in particular to an Internet of Things-based fire prevention electrical protection device and method. Background Technology

[0002] To ensure electrical safety, residual current circuit breakers (RCCBs) serve as a new type of electrical safety protection device. When the leakage current exceeds a preset value, it disconnects the circuit to prevent electrical accidents. Under normal circumstances, the vector sum of the three-phase currents is zero. Leakage from the appliance casing can cause current imbalance. To monitor current balance, RCCBs are equipped with a zero-sequence current transformer. When the transformer detects that the residual current in the circuit reaches a set value, the RCCB automatically cuts off the power. Many electrical circuits are equipped with RCCBs. Existing RCCBs only trigger power disconnection when the leakage current exceeds a threshold. When heat causes a small leakage current or a short duration, the RCCB detects the leakage and triggers power disconnection with a delay. Furthermore, RCCBs are incompatible with systems where the power supply neutral point is not grounded.

A first clamp block and a second clamp block are hinged together via an opening and closing mechanism. A first through slot and a second through slot are symmetrically arranged. The clamp assembly clamps the power supply wire between the first and second through slots using the first and second clamp blocks, utilizing the hinged action of the opening and closing mechanism for holding. The infrared sensor's detection head faces into the first through slot, ensuring that the infrared sensor can penetrate the rubber to sense the surface temperature of the power supply wire. The infrared sensor's detection head is flush with the inner wall of the first through slot, which facilitates accurate measurement. The microprocessor of the infrared-thermal sensing module receives, processes, and analyzes the data collected by the infrared sensor and the temperature sensor to determine the temperature change of the power supply wire and the temperature of the surrounding environment. The infrared sensor is an infrared temperature sensor used to measure the infrared radiation temperature of an object's surface.

[0035] The temperature sensor is used to obtain the external ambient temperature. The sensor head is flush with the outer edge of the second clamp block.

[0036] The infrared thermal sensing module is used to determine whether to generate a power outage warning mechanism and execute a command based on the temperature of the power supply wires and the external ambient temperature. The infrared thermal sensing module is also used to control the number of fans turned on in a fan array.

[0037] The infrared-thermal induction module is clamped on the power supply wire at the front end of the electrical load through a chuck assembly to monitor the temperature change of the power supply wire and the temperature of the surrounding environment.

[0038] The fan array is used for heat dissipation.

[0039] The wireless module is connected to multiple Internet of Things-based fire prevention and electricity protection devices in the building automation system.

The Internet of Things module connects to the microprocessor of the infrared-thermal induction module to receive the status and data of the infrared-thermal induction module and transmit them externally. The Internet of Things module includes a processor, a radio frequency module, a memory, an interface, etc. The Internet of Things chip 8 is connected to the Internet of Things module for data processing and data transmission.

[0043] A building automation system applied to the Internet of Things-based fire prevention and electricity protection device provided in this embodiment is shown in Figure 3.

The method includes: obtaining the temperature of the power supply wire and the external environment temperature. Determining the number of fans to be turned on in the fan array and whether to generate a power-off warning mechanism execution instruction according to the temperature of the power supply wire and the external environment temperature. The infrared-thermal induction module is also used to control the number of fans to be turned on in the fan array.

[0045] Infrared sensors monitor the temperature inside the conductor in real time, transmitting data to the microprocessor when an abnormal temperature rise is detected. Simultaneously, an ambient reference temperature is preset. The microprocessor collects and analyzes data from the infrared and temperature sensors: if the conductor surface temperature exceeds the ambient reference temperature, a warning power-off mechanism is triggered. When the warning power-off mechanism is triggered, the IoT chip controls the IoT module to transmit alarm information to external systems and handle potential fire risks.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
