[0002] Linear beam smoke detectors are widely used in large public buildings, industrial plants, and warehouses to monitor for potential fires. However, because these detectors often operate in complex power supply environments, interference between the power supply and electrical signals becomes a significant factor affecting smoke alarms. Traditional smoke detectors often fail to effectively address false alarms, malfunctions, or instability caused by power supply interference, thus impacting overall safety and reliability. Utility Model Content

[0005] Furthermore, the transceiver power supply includes a receiving power supply and an output power supply respectively arranged on the left and right sides.

[0006] Furthermore, the circuit board is connected to the receiving power supply and the output power supply respectively.

[0007] Furthermore, one of the power output channels is connected to the signal module, and each of the power output channels is respectively connected to the receiving power supply and the output power supply.

[0008] Furthermore, the circuit motherboard is powered by 12V, and the signal module is powered by 9V.

[0009] In summary, the advantages of this utility model over the prior art are:

[0010] This utility model provides a power isolation device for a linear beam smoke detector. In use, an external power supply is connected to the detector body via the transceiver power supply. The user can install a DC-DC converter module and a DC-DC converter module on the transceiver power supply. The DC-DC converter module provides overcurrent and polarity protection for the detector body. Simultaneously, the DC-DC converter module converts the voltage from 24V to the main circuit board's operating voltage of 12V. After the power isolation device receives a 12V operating voltage at its input, it converts the 12V operating voltage into an independent 9V operating voltage, which is then transmitted through… The power isolation device outputs a 9V operating voltage to the signal module, powering it. Data isolation ensures effective separation between transmitted and received signals, preventing mutual interference. Signal isolation effectively separates transmitted and received signals to prevent interference from transmitted signals, ensuring normal circuit operation. Compared to existing technologies, this device can separately power the circuit board and the signal module. Data isolation ensures voltage independence, communication data independence, and control signal independence during operation, effectively isolating external signal interference, strong electrical interference, and coupling interference. This results in a clean working environment for the beam smoke detector, high detection accuracy, good stability, and optimal sensitivity and stability. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 4The linear beam smoke detector power isolation device shown is characterized by comprising: a detector body 1, transceiver power supplies 2 disposed on the left and right sides of the detector body 1, a circuit board 3 disposed below the detector body 1, a power isolation device 4 and a signal module 5 disposed on the circuit board 3, power output channels 6 symmetrically disposed on the power isolation device 4, and data isolation 7 and signal isolation 8 disposed on the circuit board 3, wherein the transceiver power supply 2 comprises a receiving power supply 21 and an output power supply 22 disposed on the left and right sides respectively, the circuit board 3 is connected to the receiving power supply 21 and the output power supply 22 respectively, one of the power output channels 6 is connected to the signal module 5, and each of the power output channels 6 is connected to the receiving power supply 21 and the output power supply 22 respectively.

[0017] The above-described linear beam smoke detector transceiver power isolation device, in use, connects an external power supply to the detector body 1 via a receiving power supply 21. The user can install a DC-DC converter module and a DC-DC converter module on the receiving power supply 21. The DC-DC converter module provides overcurrent and polarity protection for the detector body 1. Simultaneously, the DC-DC converter module converts the voltage from 24V to the operating voltage of the main circuit board 3 (12V). After the power isolation device 4 receives the 12V operating voltage, it converts it into an independent 9V operating voltage, which is then transmitted through the power isolation device 4. The output terminal conducts the 9V operating voltage to the signal module 5. The power isolation device 4 is connected to the signal module 5 through the power output channel 6 to power the signal module 5. The transmit and receive data isolation 7 ensures effective separation between the transmitted and received signals to prevent mutual interference. The transmit and receive signal isolation 8 effectively separates the transmitted and received signals to prevent the transmitted signal from interfering with the received signal, ensuring the normal operation of the circuit. Compared with the existing technology, it can supply power to the circuit motherboard and the signal module separately, ensuring the voltage independence, communication data independence, and control signal independence of the two during operation. This effectively isolates external signal interference, strong electrical interference, and coupling interference, making the beam smoke detector work in a clean environment, with high detection accuracy and good stability, and in the most sensitive and stable working state.
