The NB-IOT narrowbands are connected to the centralization of the fire emboldens without the need to change the original fire embolism structure. Super low power, easy to retrofit, free of wiring, stable performance, easy to maintain, and well-suited ... Fire embolism 100 mm is common and can be widely applied to all types of municipal fire emboldens.
1. System Functions
Fire-fighting bolts typically have two to three outletes, ranging from 65 mm to 100 mm in diameter. Of these, 65 mm water vents were used to connect the fire-fighting belts, and 100 mm water vents were dedicated to watering fire-fighting vehicles. As a rule, all water exits are covered with smothers to prevent leakages and the corresponding smothers are torn apart by which vents are used.
The anti-flammation lid was installed with a calibre of 100 mm to replace the original 100 mm suffocation. The end-of-fire embolism intellectual suffocation does not require a change in the original fire embolism structure to allow monitoring of the water outage of the fire embolden and the timely transmission of water alarm information from the fire embolden to the main station platform via the NB-IoT. It can also be maintained wirelessly via a mobile phone.
2. Functional characteristics
Water protection:When water is released at 100 mm, when the smart lid device is twisted, the tilt switch in the device deviates from and is channeled, triggering the fire bulging smart lid to reach the main station platform by moving the alert message to the main station platform. When water is released at 65 mm, the detection of the water module within the fire-fighting embolism after the discharge triggers the same device, which sends alert information to the main station platform.
Remote function:The built-in NB-IOT module is dormant at normal intervals, reducing the equipment's effort, and the equipment reports abnormal data in the event of a change in the state of impact, fire bolts, theft of water, etc.
Timeline reporting:Regular daily reporting of equipment status data.
Positioning function:Geographic information systems (GIS) allow rapid location of fire emboldens and the geographic information management of municipal emboldens.
