Description

Technical Field

[0001] The utility model relates to the technical field of fire monitoring, in particular to a smart campus fire early warning monitoring device. Background Art

[0002] As we all know, the smart campus fire protection system mainly includes three modules: fire monitoring, monitoring management, decision-making and alarm. The three modules can be comprehensively managed through the fire Internet of Things platform to achieve real-time monitoring of campus fire safety and timely handling after accidents. Among them, the fire monitoring module needs to rely on fire hydrant monitoring devices, smoke monitoring devices, network cameras and other equipment to achieve multi-location and multi-faceted monitoring effects. Such equipment requires regular inspection and maintenance during long-term use.

[0003] The most common existing smoke monitoring device is a smoke alarm. When in use, the smoke alarm is installed on the ceiling of the fire escape. The smoke alarm includes three parts: a base, a card holder and a smoke sensor.

[0004] Existing smoke alarms may be blocked when in use, for example: 1. When stacking items, if the items are stacked too high, the smoke alarm may be blocked; 2. It is also possible that students intentionally block the smoke alarm due to mischief. When the smoke alarm is blocked, it loses its detection effect, posing a safety hazard. To address this problem, a smart campus fire early warning monitoring device can be proposed. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a smart campus fire early warning monitoring device, which has the following beneficial effects:

[0015] This kind of smart campus fire warning monitoring device, through the setting of photoelectric sensors, the photoelectric sensors can check the baffle plate. When an object approaches the photoelectric sensor, the photoelectric sensor will be triggered. After the photoelectric sensor is triggered, it will feedback an electrical signal to the controller. After the controller receives the signal, the controller controls the alarm to sound an alarm, thereby effectively preventing the smoke alarm from being blocked and avoiding safety hazards.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3The utility model is a smart campus fire early warning monitoring device, including a shell 1, the shell 1 is provided with an installation cavity 2 with an opening on one side, a smoke sensor 6, a controller 7 and an alarm 8 are installed in the installation cavity 2, a baffle 4 is installed at the opening of the installation cavity 2, a plurality of ventilation holes 5 are provided on the baffle 4, and a photoelectric sensor 9 is provided on the baffle 4. When an object approaches the photoelectric sensor 9, the photoelectric sensor 9 will be triggered. After the photoelectric sensor 9 is triggered, an electrical signal is fed back to the controller 7. After the controller 7 receives the signal, the controller 7 controls the alarm 8 to sound an alarm to prevent the smoke alarm 8 from being blocked.

[0022] The photoelectric sensor 9 and the smoke sensor 6 are both connected to the signal input end of the controller 7 , and the alarm 8 is connected to the signal transmission end of the controller 7 .

[0023] The controller 7 is internally provided with a signal sending module.

[0026] In summary, in this smart campus fire early warning monitoring device, when in use, the smoke sensor 6 plays the role of detecting smoke. When the smoke concentration reaches the standard, the smoke sensor 6 will be triggered. After the smoke sensor 6 is triggered, it will feedback an electrical signal to the controller 7. After the controller 7 receives the signal, the controller 7 controls the alarm 8 to sound an alarm.
