[0023] Figure 1 This is a block diagram of a smoke and gas sensing system with remote alarm function according to this utility model. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to specific embodiments. The description is for explanation and not limitation of the present invention.

[0025] This utility model discloses a smoke and gas sensing system with remote alarm function, referring to... Figure 1A smoke gas sensing system with remote alarm function includes a signal amplifier, multiple smoke detectors, and a terminal alarm box. The multiple smoke detectors are respectively installed at various monitoring locations indoors (such as office corridors), and the terminal alarm box is installed at locations where people gather (such as offices or building entrances and exits). Each smoke detector includes a housing, in which a smoke sensor, a processing chip, a first alarm, and a battery are disposed. The smoke sensor, processing chip, and first alarm are all connected to the battery. The probe of the smoke sensor extends out of the housing and is located on the outside of the housing. The output terminal of the smoke sensor is connected to the input terminal of the processing chip, and the output terminal of the processing chip is connected to the input terminal of the first alarm. The first alarm includes a first audible alarm and an indicator light, and the input terminals of the first audible alarm and the first indicator light are both connected to the output terminal of the processing chip.

[0026] The smoke sensor can respond quickly and accurately measure the surrounding smoke concentration. When the smoke concentration exceeds a preset threshold, the sensor immediately transmits a signal to the processing chip. Upon receiving the signal, the processing chip quickly analyzes and judges the data. Once a fire risk is confirmed, it immediately activates the first alarm. The first alarm includes a first audible alarm and an indicator light, both working synchronously. The audible alarm emits a piercing alarm sound, while the indicator light flashes to provide a visual warning, ensuring that on-site personnel can immediately perceive the danger and take appropriate measures.

[0027] The input terminal of the signal amplifier is connected to the output terminal of the processing chip, and the input terminal of the signal amplifier is also connected to the output terminal of the terminal alarm box. The signal amplifier can receive signals from multiple smoke detectors and amplify these signals to ensure that they are not attenuated or lost during long-distance transmission. The signal amplifier also has several alarm linkage positions, allowing the system to be easily expanded to meet the monitoring needs of locations of different sizes. Its low upgrade and spare parts costs, as well as its maintenance-free nature, greatly reduce the system's operating costs.

[0028] The terminal alarm box includes an outer casing. Inside the casing are a transmitter, receiver, terminal processing chip, second alarm, control panel, communicator, intercom button, and power supply. The power supply provides power to the transmitter, receiver, terminal processing chip, communicator, control panel, and second alarm. The transmitter's input is connected to the signal amplifier's output, the receiver's input is connected to the transmitter's output, and the receiver's output is connected to the terminal processing chip's input. The control panel, second alarm, and communicator's inputs are all connected to the terminal processing chip's output. The control panel displays the status of each smoke sensor, and the communicator is used to make emergency calls. The communicator can also make calls via the intercom button, allowing direct voice communication in emergencies and improving emergency response efficiency. The second alarm includes a second audible alarm and a second indicator light. The inputs of both the second audible alarm and the second indicator light are connected to the terminal processing chip's output, employing a dual alarm system of sound and indicator light to ensure the intuitiveness and effectiveness of the alarm.

[0029] In this embodiment, a mounting bracket is fixed inside the housing. The terminal processing chip is fixed on the mounting bracket, and the power supply is located below the mounting bracket. The mounting bracket ensures the stable installation of key components such as the terminal processing chip, effectively preventing the chip from loosening or being damaged due to vibration or external impact. It also ensures that the heat generated by the chip during operation can be dissipated in a timely manner, extending the service life of the device. The power supply is located below the mounting bracket, which avoids interference with other components and facilitates heat dissipation and maintenance.

[0030] The outer casing is equipped with a charging port, which connects to a power supply for charging. To prevent dust or debris from entering the charging port when not in use, a flexible plug is provided at the charging port. One end of the flexible plug is rotatably connected to the outer casing, and the other end is movablely connected to the outer casing.

[0031] This utility model discloses a smoke and gas sensing system with remote alarm function. Smoke detectors are installed in key fire prevention areas, and terminal alarm boxes are installed in densely populated places. When the smoke detector detects that the smoke concentration exceeds the threshold, it will trigger both local and remote alarms, and automatically call the contact person to notify them. This solves the problem of incomplete protection that may occur at night when there are few people around.

[0032] Specifically, the smoke sensor monitors the surrounding smoke concentration in real time through a probe extending from its housing. Once an anomaly is detected, the signal is immediately transmitted to the processing chip for analysis and processing. Subsequently, the first alarm is triggered, and the signal is also sent to the signal amplifier. The signal amplifier receives the signals from each smoke alarm, amplifies them, and then transmits them to the terminal alarm box. The receiver receives the amplified signal, and the terminal processing chip analyzes it and determines whether to activate the second alarm according to preset logic, thus realizing remote alarm. With its comprehensive monitoring capabilities, efficient signal transmission and processing capabilities, and flexible alarm mechanism, it provides a reliable security solution for various venues.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the technical solution of the present utility model in any way. Those skilled in the art should understand that, without departing from the spirit and principles of the present utility model, the technical solution can be modified and replaced in several simple ways, and these modifications and replacements are all within the scope of protection covered by the claims.
